Stopping The Saw, Incidents During Sawing

The saw WILL NOT lower to any depth greater than the position set on the BLADE DEPTH STOP SWITCH (1Q). Therefore, if a deeper cut is required, the Blade Depth Indicator MUST be turned to the new depth position. Or you can simply push the Blade Depth Stop Switch (1M) to “0” OFF to override the Depth Stop Feature.

7 Stopping The Saw

(See Figures 1-2)

For EMERGENCY STOP, press down the RED PALM SWITCH (1K) on the cowl. This will stop the engine and disconnect power to all electrical items except lights. Reset the RED PALM SWITCH (1K) by pulling out until it pops up, then restart engine.

•Move the Control Lever (1O) to the STOP (1BB) position.

•Raise the Diamond Blade (2E) out of the cut by pressing the Raise/Lower Switch (1P) on the Control Lever (1O) upward until the Diamond Blade (2E) clears the surface.

•Disengage the Blade Clutch Switch (1V) if equipped with clutch.

•Turn the Engine Throttle (1F) to the LOW IDLE position.

•Turn off the Water Valve (1T).

•Let the Engine run at idle for a few minutes before shutting off.

•STOP the engine by turning the Engine Start Switch (1H) to the “0” (OFF) position.

8 Incidents During Sawing

(See Figures 1-2)

If ENGINE STOPS during sawing, check the following:

•Engine out of fuel—Check Fuel Gauge (1X).

•Lack of water signals the Water Safety Switch (1L) to stop the engine. Set Switch (1L) to “0” (OFF) and then restart the engine.

•Excessively fast cutting speed will stall engine.

•Red Palm Emergency Switch (1K) has been pressed down. Reset by pulling toggle switch until it pops upward.

•Circuit Breaker is blown (1Z). Push to Reset

If the Diamond Blade (2E) STOPS during sawing, check:

•Drive belt tension is inadequate.

•The clutch switch has been pushed to “0” OFF

•The clutch has an electrical failure or blown fuse.

SAW LOWERS TOO FAST:

•The lowering rate of the saw can be adjusted using the Flow Control Valve (1U) at the rear or the saw. If the saw falls too quickly, turn the knob on the Flow Control Valve (1U) CLOCKWISE until an adequate lowering rate is set.

If the ENGINE or BLADE STALLS for any reason, raise the blade completely from the cut, inspect the machine thoroughly before restarting the engine. When lowering the blade into a partial cut, align the blade exactly with the cut to prevent damage to the blade.

Entrust all repairs to your authorized dealer only.

9 Adjustments: Straight Line Sawing

(See Figures 1 and 4)

While cutting, the saw may steer to the right from the required straight line marked on the cutting surface (if the Diamond Blade (2E) is installed on the right hand side). If this occurs, the Rear Axle (4E) of the saw can be pivoted to compensate for this situation.

Saw with EASYTRACK option.

•Push Axle Adjustment Switch (1J) to the LEFT. Small short adjustments make large changes.

•Adjustments can be made while sawing or not sawing.

•Visually confirm the axle movement and direction.

Saws with Manual Axle Adjustment

•The axle (4E) is adjusted by turning the M12 Adjustment Bolt (1CC) located at the rear lower left of saw frame.

•If the saw steers to the RIGHT while sawing, Turn the Adjustment Bolt COUNTERCLOCKWISE.

•If the saw steers to the LEFT while sawing, Turn the Adjustment Bolt (1CC) CLOCKWISE.
