CONCRETE SAW OPERATING INSTRUCTIONS
3. Turn off water valve. If saw is equipped with the optional
electric water pump, make sure it is turned off.
4. Close engine throttle to idle position. Let engine cool down
before stopping.
5. Do not leave the saw until the blade and saw has completely
stopped.
TO TRANSPORT SAW
1. When transporting the saw from location to location, be sure
the transmission drive system is engaged. The speed control
handle must be in the neutral position.
2. Lower the saw completely (by pressing the push button on
the right side of the speed control handle) to relieve the
weight on the front axle assembly and depth stop.
3. For prolonged hauling, the saw should be blocked and
chained to prevent undue stress and strain on the propelling
drive mechanism.
MAINTENANCE INSTRUCTIONS
1. Lubricate the blade shaft bearings daily! Lubricate when
sawing is finished for the day. Do not lubricate while the saw
is in operation. Note, when cutting dry, lubricate blade shaft
bearing two or three times daily. Use only premium lithium-
based grease conforming to NLGI No. 2 consistency. All
other fittings should be greased after every 40 hours of
operation.
2. Check the engine oil daily. Keep oil clean and at proper
level. Since the engine often operates at an angle, check
the engine oil level (with the engine horizontal) frequently to
ensure that the oil level never fails below the minimum mark
on the dip stick. Follow the engine manufacturer’s
recommendations for changing oil.
3. Clean air filter outer element when the restriction indicator
red signal appears. Do not clean inner safety element!
Replace inner element annually or if it becomes damaged.
Clean pre-cleaner dust bowl when dust accumulates.
4. Check hydrostatic transmission oil daily. Check level in
transparent oil reservoir. When adding oil use SAE 30 API
classification SE, CC, CD or better. Do not use multiple
viscosity oils. For Eaton transmission, DEXRON II automatic
transmission fluid should be visible in clear tube. If low, add
fluid to hydraulic lifting pump.
5. Hydraulic lifting pump. Check oil level periodically. Add
DEXRON II transmission fluid to bring oil level to full. Do not
overfill, or fluid will be expelled through fill cap when lowering
saw. System capacity is 1.25 quarts.
6. Blade shaft V-belts tension: This model concrete saw is
equipped with 3VX premium V-belts. These belts are
properly tensioned at the factory. Severe damage or even
breakage of the crankshaft might occur if the belts are
tensioned too tight. Check belt tension as set on the new
saw and never set belts beyond original factory tension. Not
enough tension will result in poor saw performance and short
belt life. Belts should never be allowed to slip. After four
hours of use, re-tension belts to make up for initial stretch.
To re-tension the belts, turn engine off. Loosen the four bolts
on the front of engine base clockwise until the belts are tight.
Re-tension the four belts on the engine base. Continue to
check the belt tension on a daily basis, and re-tension as
necessary. To obtain accurate V-belt setting, a V-belt
tension tester should be used. Check the setting on a single
belt of a matched set of V-belts. Apply load on the center of
the span. Deflection should 5/16” with a 5 to 6 lb. load.
7. Hydrostatic transmission cooling fins: Do not allow the
fan or cooling fins of the transmission to become covered, or
clog with dust or dirt. This will not allow proper cooling of the
transmission oil.
8. Loose chain drive: The chain drive will stretch during
normal operation. It can be tightened by loosing the four
transmission attaching bolts and moving the transmission up
in the slots of the transmission platform. Do not over tighten
chain, but allow a slight amount of slack. Lubricate chain
with oil to reduce chain wear.
9. Tighten fasteners regularly: Nuts and bolts may become
loose particularly after the first few hours of operation.
10. Engine care: See engine manual, clean dust and dirt from
cooling fans daily, or as required, to provide adequate
cooling.
CUTTING DEPTHS
BLADE SIZE MAXIMUM DEPTH
14” 4-5/8”
20” 7-5/8”
26” 10-5/8”
