NOTE: These starting instructions are general guidelines only. Since many engine options are available,
consult the Engine Manual included with this unit for specic instructions.
CAUTION: Gasoline Engines: To improve the engine service life, allow the engine to idle without load for
(2) to (5) minutes before shutting it down. When the idling period is up, use the stop switch located on the
engine and turn it to stop. Close the fuel valve under the gas tank. Engine ooding can occur if the valve
is left open during transport
TO START CUTTING
1. Start engine and let engine warm up. AII cutting is done at full throttle.
2. Align blade and cutter with cut If wet cutting. Open water valve and turn water safety switch on
3. Step on the left side of PEDAL untiI hear a “click”, then turn on the WHEEL HANDLE on the top
of the machine to remove the equipment forward and reverse step down the right side of PEDAL to
change to “push” driving system.
4. Lower blade into cut slowly.
5. Cut as fast as blade will allow If blade climbs out of cut reduce forward speed or depth of cut.
6. Use only enough side pressure on cutter handles to follow cutting line.
Cutting/Belts & Pulleys
CUTTlNG
Lower the blade into concrete to required depth by turning the tilt crank counterclockwise. Ease the saw
slowly forward. Slow forward pressure if the saw begins to stall.
NOTE: For deeper cuts (4 inches/102mm or more) several cuts should be made in incremental steps of
1-1/2 inch (38mm) to 2 inches (51 mm) until the desired depth is reached.
Push the saw steadily forward using the front pointer as a guide. Exert enough forward pressure so that the
engine/motor begins to labor,but does not slow down. If the saw begins to stall, retard forward movement
until full RPM is restored to the blade. If saw stalls, raise the blade out of the cut before restarting. Avoid
excessive side pressure or twisting of the blade in the cut.
BELTS & PULLEYS
NEVER MAKE ADJUSTMENTS TO V7 BELTS AND PULLEYS WHILE ENGINE IS
RUNNlNG
1. The best tension for a v-belt drive is the lowest tension at which the belts will not slip under full load.
2. Take up tension until the belts are snug in the grooves. Run the drive for about ve (5) minutes to “sear”
the belts. The impose the peak load. If the belts slip tighten them until they no longer slip at peak load.
Most new belts will need additional tensioning after seating.
3. Remember, too much tension shortens belt and bearing life.
4. Check the belt tension frequently during the rst day of operation. Check the belt tension periodically
thereafter and make any necessary adjustments.
