The manufacturer’s engine manual provides further instructions and details of operation and servicing.
CHOOSING PROPER BLADE SIZE CHOOSING PROPER BLADE SIZE Proper blade selection is a product of: ■ Understanding the capability of your saw ■ Understanding the specifications of the engine ■ Understanding the blade shaft speed of your saw ■ Understanding diamond blade operating limitations ■ The depth of cut required ■ Cutting conditions ■ Desired cutting performance requirements Engine (RPM) and Surface Feet per Minute (SFPM) Speeds This saw uses a belt drive system to propel the diamond blade.
CHOOSING PROPER BLADE SIZE Blade RPM vs. Surface Feet Per Minute (SFPM) CAUTION When choosing a blade for your cutting conditions, follow the blade manufacturer’s recommendations. Match the blade speed (blade shaft RPM) to the recommended blade surface feet per minute (SFPM). See Table 8. Verify the engine start switch is OFF before removing or installing a blade. Tighten the 5/8" blade-mounting bolt to 125-175 ft. lbs. of torque.
SPECIFIC TOOLS / SAW BLADES SPECIFIC TOOLS TO BE USED This saw is to use tools (blades) as follows: Steel core segmented or continuous diamond rim cutting wheel Any other type of tool is not to be used. SAW BLADES WARNING — Inspect Diamond Blade Failure to thoroughly inspect the diamond blade (Figure 8) for operational safety could result in damage to the blade or the saw and may cause injury to the user or others in the operating area. Discard damaged or worn blades and replace with fresh blade.
INSTALLING THE BLADE INSTALLING THE BLADE The blade can be mounted on either side of the saw to accomodate different cutting jobs. With the proper sized blade selected, reference the following procedure to install the new blade. Ensure the flange faces are kept clean and smooth as well as the inside diameter of the blade shaft. 1. Raise the saw so the blade will clear the ground when installed. 2. Remove the blade flange bolt.
INSTALLING THE BLADE CAUTION — Improper Torque An improperly torqued mounting bolt can cause the inside diameter of the blade, blade shaft, and flange bushing to quickly wear. This can result in poor cutting characteristics or premature failure of these parts requiring replacement and machine “downtime.” 2 Stacking Blades for Wide Cuts Combining, or stacking blades together to make wide cuts requires an optional bushing extension kit.
BLADE GUARDS BLADE GUARD The blade guards can be mounted on either side of the saw to accomodate different cutting jobs. The saw utilizes a tapered blade guard mounting clip that, during operation, settles in the taper by the weight of the guard locking itself into place providing a rigid, rattle-free fit. 2.
BLADE GUARDS Installing a Blade Guard: INSTALLING THE FLANGE GUARD 1. Slide the blade guard straight downward to engage the tapered mounting clip (Figure 16). The flange guard protects the blade flange when not in use. 1. Slide the flange guard onto the guard mounting tab on the frame (Figure 18). 2. Verify that the blade flange not in use is secured to the blade shaft by tightening the mounting bolt. Figure 16. Tapered Mounting Clip 2. Connect the water delivery hose to the blade guard (Figure 14).
WATER DELIVERY SYSTEMS WATER DELIVERY SYSTEM (OPTION) CAUTION When storing the saw where temperatures may drop below freezing, blow out the water lines to prevent damage to the water delivery system. 1. Connect the water supply hose to the water inlet (garden hose) fitting on the left side of the saw (Figure 5, Item 21). 2. Verify that the water hose on the saw is connected to the blade guard (Figure 14), and that the water hoses or tubes are pointed into both blade flanges. 3.
BATTERY BATTERY SETUP WARNING — Battery hazards Always recharge the battery in a wellventilated area to avoid risk of a dangerous concentration of combustible gases. Battery electrolyte contains corrosive, toxic chemical (dilute sulfuric acid). Avoid contact with eyes and skin. Figure 19. Battery and Battery Box WARNING — Shock hazards Disconnect battery cables before inspecting electrical system and never “spark” battery terminals to test for charge.
FUELING THE SAW FUELING THE SAW Priming the Fuel System This saw features a 6 gallon, clear, molded plastic fuel tank for ease of checking the fuel level. It has a central drain and a shutoff valve. The fuel tank cap is located at the front of the control panel console and a fuel gauge tube is featured on the front of the console. The saw utilizes a fuel primer bulb (Figure 21, item A) or button (item B), when fueling the saw for the first time or refilling after running out of fuel.
COLD WEATHER OPERATION/POINTER ADJUSTMENT COLD WEATHER OPERATION Block Heaters CAUTION — Block Heaters DO NOT leave optional block heaters plugged in for extended periods when temperatures may rise above 20oF (-6.67oC). The oil could “cook” inside the crankcase and damage to the engine could result. 3. Adjust the pointer rod (Item 5), by loosening the lock knob (Item 4).
RAISE-LOWER CONTROLS RAISE - LOWER CONTROLS SETTING THE DEPTH STOP The MQ SP4030 saw uses a 24-volt motor and hydraulic cylinder to raise and lower the saw. The raise-lower function is controlled by the operator through a 3-position toggle switch on the raise-lower control handle located on the operator’s control panel. The SP4030 saw uses a controlled depth stop to position and set the blade at a desired cut depth (Figure 26). Figure 24. Raise-Lower Control Toggle Switch 1.
RAISE-LOWER CONTROLS/WHEEL DRIVE SYSTEM To control the depth of cut with saw running and blade mounted: 1. Set depth indicator as outlined on previous page. 2. Loosen pointer knob (Figure 27, item 1). 3. Rotate pointer to desired depth (Figure 27, item 2). 4. Re-tighten pointer knob to lock-in cutting depth. WHEEL DRIVE SYSTEM The 4030 Series features a cable-controlled hydraulic powered gear motor system with infinite Forward-NeutralReverse (F-N-R) speed adjustment.
OPERATION STARTING AND STOPPING THE ENGINE WARNING DO NOT leave the saw unattended while the engine is running. NEVER start, park, or leave the saw unattended on a slope. CAUTION Allow the engine to warm up before increasing engine speed. DO NOT stop the engine abruptly when hot. Reduce the throttle to idle and allow the engine to run one or two minutes before turning the ignition switch off. This allows the engine to cool down preventing damage to the Turbo charger.
