MAINTENANCE LUBRICATION ENGINE VACUUM FAN SHAFT (For machines below serial number 007006) Check the engine oil level daily. The engine should be lubricated with SAE--SE/SF rated engine oil. Change the engine oil and oil filter after every 50 hours of operation. Change the engine oil more frequently if the environment is extremely dusty. The following oil grades are recommended for engines operating in the ambient temperatures listed.
MAINTENANCE MACHINE PIVOT SCRUB HEAD PIVOT There are four grease fittings which are used to lubricate the machine pivot assembly. There is an upper bearing grease fitting, a lower bearing grease fitting, and a grease fitting on each rod end of the steering cylinder. Apply grease to these fittings after every 50 hours of operation. Use a Lubriplate EMB grease (TENNANT Part No. 01433--1).
MAINTENANCE SCRUB HEAD HINGES SCRUB BRUSH IDLER PLUGS There are two grease fitting which are used to lubricate the scrub head hinges. One grease fitting is located on the underside of each of the hinges. Apply grease to these fittings after every 50 hours of operation. Use a Lubriplate EMB grease (TENNANT Part No. 01433--1). There are two grease fittings which are used to lubricate the brush idler plugs. They are located in the center of each idler plug and are covered with plastic caps.
MAINTENANCE HYDRAULICS HYDRAULIC FLUID HYDRAULIC FLUID RESERVOIR The quality and condition of the hydraulic fluid plays a very important role in how well the machine operates. TENNANT’s hydraulic fluid is designed to meet the special needs of its machines. Hydraulic fluid is stored in the hydraulic fluid reservoir. (For machines below serial number 007006) the reservoir holds up to 11.5 gal (44 L) of hydraulic fluid. (For machines serial number 007006 and above) the reservoir holds up to 14.
MAINTENANCE Check the hydraulic fluid level after every 100 hours of operation. It should be above the “add” mark on the dipstick, but not above the “full” mark when the hydraulic fluid is at operating temperature. C B ADD 4 QT. TO DRAIN THE HYDRAULIC FLUID RESERVOIR FULL A HYDRAULIC FLUID LEVEL DIPSTICK NOTE: Change the hydraulic fluid, filter, and suction strainer after every 800 hours for ALL machines that have NOT consistently used TennantTrue premium hydraulic fluid or equivalent. 02355 1.
MAINTENANCE ATTENTION! Use only new-approved hydraulic fluid to fill the hydraulic fluid reservoir. NOTE: Discard all hydraulic fluid drained from the system. Drained hydraulic fluid may contain foreign material harmful to the hydraulic system. 5. Check the hydraulic fluid level in the reservoir with the reservoir dipstick. 5. Apply a thin coat of hydraulic fluid to the seal of the new hydraulic fluid filter elements. 6.

MAINTENANCE ENGINE LUBRICATION Check the engine oil level daily. The engine should be lubricated with SAE--SE/SF rated engine oil. Change the engine oil and oil filter after every 50 hours of operation. Change the engine oil more frequently if the environment is extremely dusty. The following oil grades are recommended for engines operating in the ambient temperatures listed.
MAINTENANCE AIR INTAKE SYSTEM The importance of maintaining an air filter cannot be overemphasized. Dirt ingested through improperly installed, improperly serviced, or inadequate air filter elements wears out more engines than long hours of operation. Even a small amount of dirt will wear out a set of piston rings in just a few hours. Operating with a clogged air filter element also causes the fuel mixture to be richer, which can lead to formation of harmful sludge deposits in the engine.
MAINTENANCE 9. TO REPLACE AIR FILTER ELEMENT -CONTINENTAL ENGINES (For machines below serial number 006409) 1. Stop the engine and set the machine parking brake. FOR SAFETY: Before Leaving Or Servicing Machine; Stop On Level Surface, Set Parking Brake, And Turn Off Machine. Install the new filter element so the fins on the element are at the intake end of the air cleaner. Use care so the fins are not damaged. Tighten the wing nut attaching the element. 10.
MAINTENANCE TO REPLACE AIR FILTER ELEMENT -- GM ENGINES (For machines serial number 006409 and above) 1. Stop the engine and set the machine parking brake. FOR SAFETY: Before Leaving Or Servicing Machine; Stop On Level Surface, Set Parking Brake, And Turn Off Machine. 10. (Machines serial number 007006 and above) have a heavy duty safety element inside the standard element. Replace this element, do not clean it, after the regular element has been damaged or changed three times. 11.
MAINTENANCE CARBURETOR The carburetor has three basic adjustments. They are idle fuel mixture, fixed high speed jet, and idle speed adjustment. The idle fuel-air adjusting needle controls the idle mixture. Turning the idle adjusting needle clockwise results in a leaner mixture. Turning the idle adjusting needle counterclockwise results in a richer mixture. The high speed jet is not adjustable.
MAINTENANCE FUEL SYSTEM -- LPG E C A LPG FUEL SYSTEM The liquid withdrawal LPG fuel system is made up of five components which are: the LPG fuel tank, pressure relief valve, fuel filter lock, vaporizer-regulator, and the carburetor or electronic fuel injection system. Liquid LPG fuel flows from the LPG tank, under its own pressure, to the pressure relief valve. This valve is normally closed, preventing LPG fuel from escaping into the atmosphere.
MAINTENANCE Never operate an LPG powered machine if the LPG fuel system is leaking, or if any component in the fuel system is malfunctioning. Operating the machine under either of these conditions may cause a fire or explosion. Check for frosting. If frosting occurs on or near any LPG component, there is a possibility of an LPG fuel leak or a malfunctioning component. To locate the leak, apply a soapy water solution to the suspected area. Watch for bubbles forming in the suspected area.
MAINTENANCE Similar precautions should be taken in storing machines fitted with LPG fuel tanks. The machines may be stored or serviced inside buildings, provided there are no leaks in the fuel system and the tanks are not overfilled. While machines are being repaired inside a building, the shut-off valve on the tank must be closed, except when the engine must be operated. Changing the tank is a chance for the machine operator to carefully check the tank, fittings, and the fuel lines and fittings.
MAINTENANCE FUEL FILTER LOCK The fuel filter lock filters the LPG fuel. The fuel filter lock also stops the flow of LPG fuel to the engine when the engine is not operating, or when the engine oil pressure is less than 4 psi (30 kPa). Replace the fuel filter lock filter pack with the filter pack replacement kit every 400 hours or if diminished gas flow indicates the filter is clogged. A drain plug is provided for purging the filter bowl. Clean out the bowl when replacing the filter pack.
MAINTENANCE LPG FUEL TROUBLESHOOTING Problem Cause Remedy Engine will not start Out of fuel Replace fuel tank with full one Service valve opened too quickly -- engaging safety valve Close valve and reopen slowly Plugged fuel filter Replace filter Kinked or restricted fuel line Straighten or replace fuel line Engine out of tune Tune-up engine Oil pressure switch failure Replace oil pressure switch Fuel lock valve failure Repair or replace fuel filter lock Vaporizer-regulator failure Repair
MAINTENANCE GOVERNOR -- CONTINENTAL ENGINES (For machines below serial number 006409) The cam gear governor differs from a conventional centrifugal governor, mainly in the round steel balls used as the actuating force producer instead of pivoting masses of weight. When the governor is driven at increasing speeds by the engine, the hardened steel balls move outward forcing the conical upper race and lever assembly toward a closed throttle position.
MAINTENANCE ELECTRICAL SYSTEM DISTRIBUTOR SPARK PLUGS Clean or replace and adjust spark plugs after every 200 hours of operation. A wire gauge is best for checking the spark plug gap. A flat gauge should not be used unless the electrode surfaces have been been dressed with a small file to get parallel surfaces between the center and side electrodes. Set the spark plug gap by bending the side electrode. All spark plugs, new or used, should have the gaps checked and reset if necessary.
MAINTENANCE DISTRIBUTOR IGNITION TIMING There are two methods of checking ignition timing: with or without a timing light. The preferred method is to use a timing light in the following sequence: NOTE: Painting a line on the front pulley will make the timing mark more legible under the timing light. 3. Connect the black primary negative lead to the cylinder head cap screw or the alternator bracket.
MAINTENANCE CYLINDER HEAD BOLT TIGHTENING -GM ENGINES (For machines serial number 006409 and above) CYLINDER HEAD CYLINDER HEAD BOLT TIGHTENING -CONTINENTAL ENGINES (For machines below serial number 006409) A three-stage torque procedure should be used when reassembling the cylinder head. The cylinder head cap screws and risers must be tightened in the proper sequence after the first 50 hours of operation and after every 400 hours of operation. Snug down cap screws and risers in the proper sequence.
MAINTENANCE PCV SYSTEM Check the PCV system after every 200 hours of operation. Check all connections. They are to be airtight. To service the system, clean the PCV valve and the air inlet. Check all hoses for wear or plugging. TUNE-UP CHART -- CONTINENTAL ENGINES (For machines below serial number 006409) Idle speed, no load 600 + 50 rpm Maximum governed speed 2400 + 50 rpm Spark plug gap 0.035 in (0.
MAINTENANCE ELECTRICAL SYSTEM BATTERY The battery is rated at 12 V, 540 ccA. The battery is located in the engine compartment. When removing battery cables, remove the negative (--) cable before the positive (+) cable. Do not allow the battery to remain in discharged condition for any length of time. Do not operate the machine if the battery is in poor condition or only 25% of the charge is left. Clean the top surface and the terminals of the battery periodically.
MAINTENANCE BELTS AND CHAINS VACUUM FAN DRIVE BELT (For machines below serial number 007006) ALTERNATOR AND RADIATOR FAN BELT The vacuum fan drive belt tension should be checked after every 50 hours of operation. The proper belt tension for gasoline and LPG machines is obtained when the midpoint of the belt deflects 0.34 in (9 mm) from a force of 7 to 8 lb (3.2 to 3.6 kg). TO ADJUST VACUUM FAN DRIVE BELT The alternator and radiator fan belt tension should be checked after every 100 hours of operation.
MAINTENANCE SCRUB HEAD SCRUB HEAD The scrub head houses the two scrub brushes and the brush drive mechanisms. The scrub head has two adjustments; scrub head height, and scrub brush pattern. 3. Adjust the nut so that the top front of the head is 13.62 in to 13.75 in (345 to 350 mm) from the floor. The scrub head height adjustment sets the minimum scrub head height. The height adjustment should not be changed unless, due to a major parts replacement or collision, the head adjustment may have been altered.
MAINTENANCE 5. The rear brush polish mark is the most critical and should be adjusted first. If the polish mark is uneven or cone shaped from one end to the other, the brush leveling spring located at the operator side of the head lift, should be adjusted. The spring compensates for the weight of the brush drive motors. Loosen the top nut first to make the adjustment. 6. The polish mark of the front brush should match the polish mark of the rear brush.
MAINTENANCE 7. Recheck the brush polish marks to see if the front and rear match, and are even across the full length of the brush. 8. The width of the rear brush polish mark can vary more than the desired 2 to 3 in (50 to 75 mm). There are adjusting knobs located on the drive side of the scrub head. Turn the knob clockwise to decrease the width of the polish mark and counterclockwise to increase the width of the polish mark. The polish mark should not exceed 3 in (75 mm).
MAINTENANCE 6. Repeat steps 4 and 5 to remove other brush. 7. Insert one end of brush through access door and push the brush in until it touches the drive plug. It is helpful to have a second person guide the other brush end onto the drive plug while you are pushing and turning the brush until it engages the drive keyway on the plug. 8. Install the brush arm with the hex head bolt. A E D C B REPLACING BRUSH A. B. C. D. E. 00287 Door Brush Arm Brush Brush Drive Plug Raised Scrubber Head 9.
MAINTENANCE SOLUTION SYSTEM RECOVERY TANK The recovery tank has a capacity of 120 gal (455 L). When the tank is full, a ball float will rise and shut off the vacuum to the tank. A 48 in (220 mm) long drain hose for the recovery tank is located on the front of the tank. You can determine the water level in the recovery tank by lowering the hose end until water appears -- this will then be the water level in the tank, (engine must be off; this stops vacuum).
MAINTENANCE SRS WATER SPRAY DEFLECTOR A The SRS solution tank has two spray deflectors; a lower spray deflector located on the rear squeegee discharge tube inside the tank, and a top spray deflector located in the top rear of the tank. The spray deflectors deflect the spray of water and small debris away from the walls of the solution tank. The deflectors should be checked for wear after every 200 hours of operations.
MAINTENANCE SRS SOLUTION TANK The tank has a capacity of 265 gal (1000 L). When the tank is full, a ball float will rise and shut off the vacuum to the tank. A 72 in (1830 mm) long drain hose for the recovery tank is located on the front of the tank. You can determine the water level in the tank by lowering the hose end until water appears--this will then be the water level in the tank, (engine must be off; this stops vacuum). To drain the tank, lower the hose and place in suitable floor drain.
MAINTENANCE Motor Operates, But No Pump Discharge SOLUTION DISPENSING TUBE The solution dispensing tube has a flushing connection built in. The flushing connection is the tee fitting next to the solution control valve. This allows a garden hose to be threaded into the dispensing system to flush the system. Flush the system after every 50 hours of operation. 1. Damaged bellows. 2. Restriction in cleaning solution lines. 3. Air leak in intake line. 4. Unprimed pump.
MAINTENANCE SQUEEGEES SIDE SQUEEGEES The side squeegees control scrub brush water spray. They consist of a squeegee blade, backup strip, band, and clamp. Check the side squeegee blades for damage or wear daily. Replace squeegee blade by opening the quick-release latch and removing the band. Remove the bracket, old blade, and backup strip. Replace the squeegee blade and backup strip if the blade is worn. Lower the head and adjust the squeegee so that the blade deflects 0.50 in (13 mm).
