Tasks Prior to Starting the Engine/Motor

Make sure to complete the following tasks prior to starting the engine/motor:

•Fill all liquids to appropriate levels for proper saw operation.

•Turn off water valve.

•Turn off water pump.

•Set speed control lever at Neutral (self-propelled model).

•Disengage transmission (self-propelled model).

•Set engine throttle to slowest position (gas saw).

•Turn off hydraulic ball valve (hydraulic motor saw).

•Remove tools from work area.

•Raise blade off ground.

Starting the Engine/Motor

Gasoline Engine

1.Open the fuel shutoff valve or move the fuel shutoff lever to the open or on position.

2.Close the choke. Note: When restarting a warm engine, open the choke.

3.Increase the throttle by approximately 1/3 (Honda engine). Increase the throttle to FAST (Briggs Vanguard engine).

4.Turn on the engine switch (applicable models).

5.Pull the recoil starter handle backward slowly until resistance is felt, and then pull the handle backward quickly (applicable models). Gently return the handle and repeat if the engine does not start. Note: Refer to the engine manual for troubleshooting recommendations after several failed attempts.

6.Insert the key into the ignition, turn the key to Start, and release the key when the engine starts (applicable models). If the engine does not start, release the key and try again shortly. Note: Refer to the engine manual if the engine does not start after two attempts.

7.Decrease the throttle to the slowest position. Gradually open the choke while the engine warms up.

8.Increase the throttle to the fastest position and adjust the throttle as necessary for maximum efficiency. DO NOT exceed the maximum recommended cutting speed when operating the saw.

Electric Motor

1.Plug the saw into an outlet or generator. Refer to Diamond Products for a list of recommended power cord gauges. Note: DO NOT supply less power or more power, through the power source, to the motor than what the motor is rated for.

2.Press the start button on the starter box.

Hydraulic Motor

1.Connect the return hose from the hydraulic power unit to the return line quick disconnect on the saw.

2.Connect the pressure hose from the hydraulic power unit to the pressure line quick disconnect on the saw. Note: The motor will not start if the hoses are improperly connected.

3.Turn on the hydraulic power unit.

4.Push the ball valve on the saw down 90° to open the valve and start the motor. Adjust the flow control on the hydraulic power unit to increase/decrease the motor speed. DO NOT exceed the maximum recommended blade speed when cutting. DO NOT use a hydraulic power unit that will supply less power to the hydraulic motor than required.

Stopping the Engine/Motor

WARNING

•DO NOT disconnect hydraulic hoses when the saw is running.
