OPERATION
1.Connect the saw to your water source and start the engine as described in the previous section.
2.Rotate the throttle lever (Figure 22) to full throttle.
3.Turn the water valve to start the flow of water and ensure sufficient water supply is directed to both sides of the diamond blade.
4.Release Parking Brake by pulling Lever UP.
Figure 24. Parking Brake
5.To begin sawing, rotate the Raise/Lower Wheel until the desired depth is referenced on the Depth Indicator Ring.
6.When the blade has reached the desired depth of cut, flip the Depth Stop Latch down into position within the Raise/Lower Wheel.
7.Walk the saw slowly forward at a rate that permits the diamonds to grind without losing optimum blade RPM.
8.When cutting is complete, turn the engine OFF using the ENGINE STOP TOGGLE SWITCH on the handlebars and wait for the blade to stop rotating.
9.Set the engine ON/OFF switch to the OFF position.
10.Place the water valve in the OFF position (as required).
11.Push the Parking Brake Lever downward to apply braking pressure to the wheels.
Restarting After Intervention
If cutting is interrupted where the engine stops or is turned off while the blade is still in the cut:
1.Turn Engine Off switches to OFF
2.Raise the blade out of the cut
3.Restart the engine as described in the previous section.
4.Recheck the integrity of the diamond blade.
CAUTION
The only acceptable method for freeing a stuck blade is to remove the saw from the stuck or pinched blade. DO NOT try to get the blade unstuck using the Raise/ Lower system or by lifting the saw by the lifting bale, etc.
If cutting is interrupted where the blade is stuck in the cut:
1.Turn Engine Off switches to OFF.
2.Remove the blade guard.
3.Remove blade mounting bolt and outer flange.
4.Maneuver the saw away from the stuck blade.
5.A parallel cut made next to the blade may be necessary to free it.
6.Once the blade is freed inspect the blade for damage; discard if damaged.
7.Ensure an undamaged, useable blade is installed on the saw before cutting is resumed with that saw.
