CAUTION

•DO NOT leave the saw unattended until the engine/motor is off and the blade has stopped spinning.

Gasoline Engine

1.Decrease the throttle to the slowest position for several minutes.

2.Hold down the stop button (on the control panel) to stop the engine (applicable models). Note: This action does not permanently stop the engine.

3.Turn off the engine switch (applicable models). Note: Turning off the switch will stop the engine permanently and will prevent the blade from spinning unexpectedly.

4.Turn the ignition key to Off and remove the key (applicable models).

5.Close the fuel shutoff valve (if desired).

Electric Motor

1.Press the stop button on the starter box.

2.Disconnect the power cord from the saw and from the outlet or generator.

Hydraulic Motor

1.Decrease the hydraulic flow on the hydraulic power unit.

2.Push the ball valve on the saw up 90° to close the valve and stop the motor.

3.Decrease the hydraulic flow to the minimum (or stop position) on the hydraulic power unit.

4.Turn off the hydraulic power unit.

5.Disconnect the hydraulic power unit’s pressure hose from the pressure line quick disconnect on the saw.

6.Disconnect the hydraulic power unit’s return hose from the return line quick disconnect on the saw.

Concrete Cutting

WARNING

•DO NOT expose yourself or anyone else to the direct line of the blade when operating the saw.

•Turn off all electricity, gas, and water around the direct work area prior to cutting.

•When using an electric motor saw, be aware of all active electrical lines if using power from the direct work area to operate the saw.

Helpful Hints Prior to Cutting

Keep the following things in mind for greater efficiency when cutting:

•Use just enough handle pressure to guide the saw on the cutting line. DO NOT forcibly direct (twist) the saw from side-to-side when cutting.

•Avoid sawing excessively deep to preserve the blade and reduce sawing costs.

•Moving too quickly when cutting may stall the saw or may cause the blade to climb out from the cut. If the saw stalls at any time, move the speed control lever to Neutral (self-propelled model), raise the blade from the cut, and restart the engine/motor.

•DO NOT lower the blade too quickly or move the saw forward too quickly when finishing a partial-cut to avoid forcing the blade into the concrete.

Tasks Prior to Cutting

Complete the following tasks prior to cutting:

•Raise the blade to provide proper clearance between the blade and the ground when maneuvering the saw.

•Align pointer assembly with the blade.

•Clearly mark the cutting line.

•Be sure the work area does not contain any buried or embedded electrical, gas, or water lines.

Making a Cut

1.Turn on the water valve. Note: Always use a proper water pressure and flow when cutting.

2.Turn on the water pump (as necessary).

3.Align the blade and front pointer with the cutting line.

4.Lower the blade into the concrete slowly, in two-inch increments, to reach the desired cutting depth. DO NOT cut any deeper than required.

5.Use the speed control lever (self-propelled model) or push (push model) the saw forward, at a proper speed, to continue down the cutting line. Cut as fast as the blade allows; if the blade climbs out of the cut reduce the forward speed and/or cutting depth. Raise and lower the blade as necessary while cutting.

Continuing a Partial-Cut

1.Align the blade with the previous cut and lower the blade back into the cut. DO NOT move forward unless the blade is properly aligned within the cut.

2.Use the speed control lever (self-propelled model) or push (push model) the saw forward, at a proper speed, to continue down the cutting line. Raise and lower the blade as necessary while cutting.

Finishing a Cut

1.Place the speed control lever at Neutral (self- propelled model), or stop the saw (push model).

2.Raise the blade from the cut (high enough for proper ground clearance).

3.Turn off the water valve.
