OPERATION (GASOLINE)

4.Rotate the throttle lever (Figure 27) halfway between fast and slow for starting. All cutting is done at full throttle. The engine governor speed is factory set to ensure optimum blade operating speeds.

6.If the engine has started, slowly return the choke lever (Figure 26) to the "OPEN" position. If the engine has not started repeat steps 1 through 5.

7.Before the saw is placed into operation, run the engine for severalminutes. Checkforfuelleaks,andnoisesthatwould associate with a loose guards and/or covers.

8.Gradually move the engine throttle lever toward the fast position. (All cutting should be done at full throttle).

9.Squeeze the water pump priming bulb (Figure 29)until water begins to flow through the

water lines. If the pump is working correctly, the cutting blade should be covered with a steady water mist. This will keep the blade cool.

WARNING

ALWAYS cut with the saw at FULLTHROTTLE. Attempting to cut with the saw at less than full throttle could cause the blade to bind or stop abruptly in the slab resulting in serious injury to the operator or others in the area.

DANGER

ALWAYS be alert to the fact that there is a rotating blade on the saw and be extremely aware of your body position - especially your hands in relationship to the rotating blade.The possibility exists of severe bodily harm even death if your body comes in contact with the rotating saw blade.

10.Push the conveyor cart with the material, slowly and evenly until the cut is complete. Move the cart back and remove the cut pieces.

11.Avoid overloading the engine when cutting. In the event that the engine becomes overloaded, turn the engine ON/OFF switch to the OFFposition and allow the engine to cool before attemptingtorestart.

STOPPING

WARNING

DO NOT

NEVER

1. Set the engine throttle lever to slow speed and let the engine idle for 3-5 minutes.

2.Turn the engine ON/OFF switch to the "OFF" position.

3.Place the fuel valve lever in the closed position.

4.Let the engine cool.

5.Using a soft cloth, clean any excess debris or residue that may have accumulated on the saw.

6.Store saw in a clean dry location where it will be out of the reach of children.
