GENERAL INFORMATION CONCRETE MIX DESIGN Mix design is most important to achieve maximum pumpability. Pumpability is affected by, among other factors, the type and gradation of aggregate used. Natural aggregates make a more workable mix and pump more readily than crushed aggregates. A blend of natural and crushed aggregates will produce a workable mix. The type and gradation of aggregates is equally important for workability as the size and percentage of coarse aggregates in the mix.
GENERAL INFORMATION REGIONAL DIFFERENCES Concrete is made by mixing locally available rock and sand with cement and water. For this reason there are great differences in the pumpability of concrete from one region of the country to another. It is impossible to define a specific mix for each region that the concrete pump be will working in. Therefore, the mixes listed in Appendix - Concrete Mix Information will provide a basic guideline for establishing the proper mix design for your area.
HOW IT WORKS The following is a brief explanation of how the concrete cylinders, hydraulic cylinders, shuttle tube, valves and hopper work in sequence to pump concrete. The hydraulic pressure is generated by a variable volume, pressure compensated, axial piston pump that is driven by a diesel engine. The rod sides of the drive cylinders are hydraulically connected together creating a “slave circuit,” which allows hydraulic oil to transfer from one piston to the other.
PUMP COMPONENTS Figure 5. Major Pump Components PAGE 18 — MAYCO LS300 CONCRETE PUMP • OPERATION AND PARTS MANUAL — REV.
PUMP COMPONENTS Figure 5 illustrates the location of the major components for the LS300 Concrete Pump. The function of each component is described below: 1.

Turn knob counterclockwise to disengage the stop button. Ignition Switch – Insert the ignition key here to start the engine. Turn the key clockwise to the ON position, then continue turning clockwise to the START position and release. To stop the engine turn the key fully counterclockwise to the STOP position.
DIGITAL READOUT SCREEN PRIMARY SCREEN Screen 1 Indicates the various modes of the switch settings. Monitors engine RPM - Idle speed 900, High speed 2550. Battery charge indicator - Normal charge 13+ volts. Indicates electrical malfunction - Refer to Troubleshooting section. Screen 5 Displays the ON/OFF electrical signal status of the various 12 volt solenoids (Swing A circuit, Main A circuit, Main B circuit).
ENGINE COMPONENTS Figure 7. Deutz TD2009L04 Diesel Engine Components INITIAL SERVICING The engine (Figure 7) must be checked for proper lubrication and filled with fuel prior to operation. Refer to the manufacturer's engine manual for instructions and details of operation and servicing. 1. Fuel Filter – Service the fuel filter as recommended in the maintenance section of this manual. 2. Oil Filter – Prevents dirt and other debris from entering the engine.
INSPECTION CAUTION - GENERAL SAFETY GUIDELINES FUEL CHECK 1. NEVER operate the pump in a confined area or enclosed area structure that does not provide ample free flow of air. Check the fuel gauge built into the fuel tank cap (Figure 8) to determine if the pump's engine fuel is low. Refuel as needed. WARNING - EXPLOSIVE FUEL Diesel fuel is extremely flammable, and its vapors can cause an explosion if ignited. DO NOT start the engine near spilled fuel or combustible fluids.
INSPECTION ENGINE OIL CHECK 1. Remove the engine oil dipstick from its holder (Figure 10). 6. The oil listed in Table 4 is recommended to ensure better engine performance. Use class CD or higher grade motor oil. Figure 10. Engine Oil Dipstick 2. Make sure pump/engine is placed on level ground. HYDRAULIC OIL CHECK 3. Pull the engine oil dipstick (Figure 11) from its holder. 1. Determine if the hydraulic oil level is low by observing the level of the oil in the Hydraulic Oil Sight Glass (Figure 12).
INSPECTION 2. If the hydraulic oil level is low, remove the cap just above the oil level sight glass (Figure 13) and add the correct amount of hydraulic oil to bring the hydraulic oil level to a normal safe operating level. (Use Shell oil Tellus 68 or Mobil oil DFE26). Figure 13. Hydraulic Oil Filler Hole 3. Check the oil level in the lubrication box. If low, fill with up to 3 gallons of SAE #30 motor oil (Figure 14). The oil level must be checked daily.
SET-UP LOCATION OF PUMP 1. Place the pump in the best location on the site to pump concrete efficiently. 2. Lay down the hose in the shortest distance possible. REAR STABILIZER JACKS To reduce excessive vibration and rocking of the pump, set the rear stabilizers as follows: 1. Locate both the left and right rear stabilizer jacks (Figure 15). Figure 17. Rear Stabilizer Stand Deployment WARNING - REAR STABILIZER SAFETY NEVER place feet under jack while operating.
START-UP PROCEDURE 4. Place the Direction Control Switch to the FORWARD position (Figure 22). STARTING PROCEDURE WARNING - GENERAL SAFETY GUIDELINES DO NOT attempt to operate this concrete pump until the Safety, General Information and Inspection sections have been read and understood. REVERSE Figure 22. Direction Control Switch (FORWARD) 5. To start the engine, insert the key (Figure 23) into the ignition switch and turn the key to the ON position. e nc y S erg to p Em 1.
OPERATION HOSE LUBRICATION Before pumping, it is necessary to lubricate the hose. PUMPING WARNING - SAFETY GLASSES This procedure prevents separation and blockages in the hose. Inspect the lines at all times to prevent problems. Safety glasses MUST be worn at all times when operating the pump. Failure to follow safety guidelines can result in serious injury.
OPERATION 3. Scroll through the Digital Readout Screen with the scroll switch to go to Screen 7 (Figure 28). This screen will show the volume in strokes per minute. THROTTLE ON 7 STROKES: 100 STROKES/MIN 10.0 YDS/HR 0.0 Figure 28. Strokes Per Minute Display 4. Let the pump cycle until the hydraulic oil temperature (Figure 29) is approximately 50° to 60° F.
OPERATION REMOTE CONTROL (OPTIONAL) 4. Reinstall the control panel and tighten the 2 screws. The LS300 Concrete Pump has a remote control feature that allows the pump to be remotely controlled. If desired, the pump can be operated via a receiver/transmitter (radio) or a hardwire method, which utilizes a 25-ft. extension cable. Contact MQ Sales Department to order remote control. 5.

Press the ON/OFF button on the radio (wireless) remote control to turn on the power. Hold down the RESET switch. The display will now show: RADIO ADDRESS 9 NOW SCANNING FOR NEW TRANSMITTER 2.
PUMPING INFORMATION REMIXTURES Remixtures that are designed into the concrete mix by the redi-mix company or an architectural engineering company. This section lists common admixtures and a brief explanation of their functions: A. Pozzolith 300 – or the equivalent acts as a water retarder and a lubricant. On a lean mix, long pushes, stiff mixes, and vertical pushes, Pozzolith 300R helps pumpability. B. MBVR – air entraining, acts as a lubricant. C. Calcium Chloride – commonly referred to as C.C.
PUMPING INFORMATION The use of 2 -1/2” I.D. hose in these extreme cases reduces line pressures or the addition of slight amounts of water to the mix, if permissible, will permit easier pumping. The use of certain pumping admixtures may help.
PUMPING INFORMATION Using this procedure will make it easier to pump through the clean hose. Note: Once the concrete has reached the end of the hose, do not apply any more water in this manner as this procedure is used for starting only. 6. Hose sizing is very important: We strongly recommend on harsh mixes, vertical pushes, stiff concrete, shotcrete, long pushes, that a 2 -1/2” line be used as far as possible.
PUMPING INFORMATION CLEARING SHUTTLE TUBE BLOCKAGE The shuttle tube is plugged if volume at the discharge end of the hose stops and the hydraulic oil pressure gauge reads 3100 PSI or more. To clear a plug in the shuttle tube, great care must be taken as a dangerous condition will exist from pressure build-up inside the shuttle tube. (With the shuttle valve, the concrete can be pumped in reverse.) Use the following procedures to clear the shuttle tubes.

Clean Hydraulic Filters Axle Crank X 2100 hrs. X Grease Shuttle Tube Zerk Points X 2 h rs Check System Pressure X 40 hrs. Check Hardware for Tightness X 40 hrs.
MAINTENANCE (PUMP) 5. Add water to the hopper. Pump and flush clean the entire hopper, shuttle tube and discharge elbow with water. 6. Scoop out 12 inches of concrete from the inboard end of the delivery hose. “Cork screw” a 6" x 6" x 8" sponge into the end of the first hose section. Reconnect the hose to the discharge elbow. 7. Fill hopper with water. Pump until sponge and clean water come out the discharge end of the hose and line system. 8.
MAINTENANCE (PUMP) BATTERY MAINTENANCE CAUTION - BATTERY MAINTENANCE SAFETY Wear safety glasses or face mask , protective clothes, and rubber gloves when working with battery. Mishandling of the battery shortens the service life of the battery and adds to maintenance cost. When handling the battery do the following: Be careful not to let the battery electrolyte come in contact with your body or clothing.
MAINTENANCE (PUMP) CYLINDER LUBRICATION BOX WARNING - FREEZING CONDITIONS When using the pump during freezing conditions, completely drain the water box and cover the hopper after pumping. Frozen liquid will restrict the piston travel and cause severe damage to the pump. CAUTION - SAFETY GUIDELINES Before checking lubrication level, stop the engine and remove the engine starter key. 1.
MAINTENANCE (PUMP) WEAR PLATE AND CUTTING RING Due to the abrasive nature of concrete, it is normal for the cutting ring to wear on its sides as it shears through the concrete inside the hopper. The metal-to-metal friction and the abrasiveness of the concrete will cause extreme wear and reduce sealing capability between the cutting ring and wear plate. If the two components do not properly seat against each other, slurry will pump into the hopper rather than out the discharge line. See Figure A.
MAINTENANCE (PUMP) CHANGING THE CONCRETE CYLINDER PISTON CUPS 6. The Rubber piston cups will occasionally require replacement depending on the following factors. Remove the three 3/8 – 16 x 3” bolts from the piston. Remove the front faceplate. 7. Install two the 3/8’ 16x3” bolts back into the piston – do not tighten. Use the two bolts as leverage to remove the rubber piston cup and rear components. 8.
MAINTENANCE (PUMP) CHANGING THE WEAR PLATE AND RING Wear Plate Installation Due to the swinging motion of the Nun-plate and the abrasive nature of concrete, it is normal for the cutting ring to wear on the side that shears through the concrete inside the hopper. If the wear ring and wear plate do not fully seat against each other the concrete slurry will pump into the hopper. This condition can be easily observed by the sudden change of the level of concrete inside the hopper during each stroke. 1.
MAINTENANCE (PUMP) WHEEL BEARINGS PRESSURE TEST After every 6 months of operation inspect the wheel bearings. Once a year, or when required, disassemble the wheel hubs remove the old grease and repack the bearings forcing grease between rollers, cone and cage with a good grade of high speed wheel bearing greases (never use grease heavier than 265 A.S.T.M. penetration “No. 2.”). 1. To determine the pressure of the Hydraulic System, set the Cylinder Stroke Control Switch (Figure 42) to the JOG position.
MAINTENANCE (TRAILER) The following trailer maintenance guidelines are intended to assist the operator in preventive maintenance. Trailer Brakes Properly functioning brake shoes and drums are essential to ensure safety. The brakes should be inspected the first 200 miles of operation. This will allow the brake shoes and drums to seat properly. After the first 200 mile interval, inspect the brakes every 3,000 miles. If driving over rough terrain, inspect the brakes more frequently.
MAINTENANCE (TRAILER) Periodically check the actuator mounting fasteners for damage or loosening. Inspect the actuator for worn or damaged parts. As you are towing your trailer, be aware of any changes in braking quality. This could be an early warning of brake or actuator malfunction and requires immediate attention. Consult a certified brake specialist to make necessary adjustment or repairs.
MAINTENANCE (TRAILER) Danger - Raising the Trailer NEVER crawl under the trailer unless it is on firm and level ground and resting on properly placed and secured jack stands. The possibility exists of the trailer falling thus causing equipment damage and severe bodily harm even death! Torsion Suspension The mounting bracket (Figure 49) of the torsion suspension assembly is bolted directly to the trailer frame.
TRAILER SAFETY GUIDELINES TRAILER SAFETY INFORMATION ■ ALWAYS use lower gears for climbing and descending grades. Safety precautions should be followed at all times when operating this equipment. Failure to read, understand and follow the Operating Instructions could result in injury to yourself and others. Loss of control of the trailer or tow vehicle can result in death or serious injury. ■ DO NOT ride the brakes while descending grades, they may get so hot that they stop working.
TRAILER SAFETY GUIDELINES CAUTION - Local Towing Regulations Check with your county or state safety towing regulations department before towing your trailer. Driving Conditions When towing a trailer, you will have decreased acceleration, increased stopping distance, and increased turning radius (which means you must make wider turns to keep from hitting curbs, vehicles, and anything else that is on the inside corner).
TRAILER SAFETY GUIDELINES Reporting Safety Defects If you believe that your vehicle has a defect that could cause a crash or could cause injury or death, you should immediately inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying us. Trailer Towing Tips Driving a vehicle with a trailer in tow is vastly different from driving the same vehicle without a trailer in tow. Acceleration, maneuverability and braking are all diminished with a trailer in tow.
TRAILER SAFETY GUIDELINES Some drivers place their hands at the bottom of the steering wheel, and while the tow vehicle is in reverse, “think” of the hands as being on the top of the wheel. When the hands move to the right (counterclockwise, as you would do to turn the tow vehicle to the left when moving forward), the rear of the trailer moves to the right.
TRAILER SAFETY GUIDELINES Tow Vehicle The towing hitch attached to your tow vehicle must have a capacity equal to or greater than the load rating of the trailer you intend to tow. The hitch capacity must also be matched to the tow vehicle capacity. Your vehicle dealer can provide and install the proper hitch on your tow vehicle. Suspension System Sway bars, shock absorbers, heavy duty springs, heavy duty tires and other suspension components may be required to sufficiently tow the trailer and pump.
TRAILER SAFETY GUIDELINES Coupler Types The trailer is shipped from the factory with a 2-inch ball coupler. Ball Hitch Coupler A ball hitch coupler (Figure 52) connects to a ball that is located on or under the rear bumper of tow vehicle. This system of coupling a trailer to a tow vehicle is sometimes referred to as “bumper pull.” A ball hitch trailer may be fitted with a tongue jack that can raise and lower the coupler. The tongue jack is mounted to the A-frame (front, or tongue) part of the trailer.
TRAILER SAFETY GUIDELINES WARNING - Defective Hitch Ball A worn, cracked or corroded hitch ball can fail while towing, and may result in death or serious injury. 2-INCH TRAILER COUPLER TOW VEHICLE Before coupling trailer, inspect the hitch ball for wear, corrosion and cracks. Replace worn or damaged hitch ball. WARNING - Uncoupled Hitch Ball A loose hitchball nut can result in uncoupling, leading to death or serious injury. Be sure the hitch ball is tight to the hitch before coupling the trailer.
TRAILER SAFETY GUIDELINES Attaching Safety Chain TOW VEHICLE TRAILER TONGUE IMPORTANT! SAFETY CHAIN MASTER LINK Breakaway Brake System If the coupler or hitch fails, a properly connected and working breakaway brake system (Figure 55) will apply the hydraulic brakes on the trailer. The safety chains will keep the tow vehicle attached and as the brakes are applied at the trailer’s axles, the trailer/tow vehicle combination will come to a controlled stop.
TRAILER SAFETY GUIDELINES Connecting Trailer Lights Connect the trailer lights to the tow vehicle’s electrical system using the electric connectors at the front of the trailer (tongue). Refer to the wiring diagram shown in the trailer wiring diagram section of this manual. Before towing the trailer check for the following: Running lights (turn on tow vehicle headlights). Brake Lights (step on tow vehicle brake pedal). Backup Lights (place tow vehicle gear shift in reverse).
TRAILER SAFETY GUIDELINES Lug nuts are also prone to loosen after first being assembled. When driving a new trailer (or after wheels have been remounted), check to make sure they are tight after the first 10, 25 and 50 miles of driving and before each tow thereafter. Failure to perform this check can result in a wheel parting from the trailer and a crash, leading to death or serious injury.
TRAILER SAFETY GUIDELINES Step 1. Locate the statement, “The weight of cargo should never exceed XXX kg or XXX lbs.,” on your vehicle’s Tire and Loading Information placard (Figure 56). This figure equals the available amount of equipment load capacity. Step 2. Determine the weight of the equipment being loaded on the tow vehicle. That weight may not safely exceed the available equipment load capacity.
TRAILER SAFETY GUIDELINES P: The “P” indicates the tire is for passenger vehicles. Next number: This three-digit number gives the width in millimeters of the tire from sidewall edge to sidewall edge. In general, the larger the number, the wider the tire. Next number: This two-digit number, known as the aspect ratio, gives the tire’s ratio of height to width. Numbers of 70 or lower indicate a short sidewall for improved steering response and better overall handling on dry pavement.
TRAILER SAFETY GUIDELINES Reference Figure 58 for additional tire information for light trucks. Make sure your tire valves have valve caps. ALWAYS check tire pressure on tow vehicle and trailer before towing. Check tire pressure at least once a month. DO NOT overload tow vehicle. Check the tire information and loading placard for safe allowable tire loading conditions.
TRAILER SAFETY GUIDELINES WARNING - Flying Objects ALWAYS wear safety glasses when removing or installing force fitted parts DO NOT attempt to repair or modify a wheel. DO NOT install an inner-tube to correct a leak through the rim. If the rim is cracked, the air pressure in the inner tube may cause pieces of the rim to explode (break off) with great force and cause serious eye or bodily injury.
TRAILER SAFETY GUIDELINES Figure 60. Trailer to Tow Vehicle Wiring Diagram Lights and Signals Before each tow, check the trailer taillights, stoplights, turn signals and any clearance lights for proper operation. Replace any broken or burned-out lamps as necessary. Check the wire harness for cuts, fraying or other damage. If it needs replacing, contact your dealer. WARNING - Trailer Lights Improper operating taillights, stoplights and turn signals can cause collisions. Check all lights before each tow.

APPENDIX — CONCRETE MIX INFORMATION The following information has been extracted from actual testing laboratory reports. The purpose of this printing is only to help create a better understanding of the importance of uniform gradation and proportioning of materials which affect pumpability of concrete mixes. These weights and proportions illustrate that when the sieve analysis is ideal, the sand/rock ratio can be adjusted (65% sand 35% rock) and pumpability should be excellent.
