Operating the Concrete Cutter
Operators must be trained in the use of the concrete cutter and maintain practiced skill. It is
dangerous to operate this machine improperly or by an untrained person. An operator should read
and understand the manual and follow its directions.
Do not stop the engine when the concrete cutter is at high speed or the engine temperature will rise
suddenly, possibly causing engine parts to jam or the oil to deteriorate. Minimize the engine speed
and allow it to idle for a few minutes before stopping it.
Start the Engine
1. Ensure that the saw blade is off the ground. If not, turn the height adjust handle clockwise to
raise the blade off the ground.
2. Check that the throttle switch is pushed fully away from the operator.
3. Open the fuel valve on the engine.
4. Turn the engine switch to ON.
5. Choke the engine. A warm engine may not need to be choked.
6. Pull the starter rope to start the engine.
7. Open the choke and allow the engine to warm up at slow speed for 5 minutes.
Operation
Start Cutting
1. Turn the height adjust handle clockwise raise the saw blade off the ground and move the cutter to
the cutting area.
2. Align both saw blade and the guide wheel on the cutting line.
3. Pull the throttle lever back toward the operator to increase the speed of the engine.
4. Turn the height adjust handle counter-clockwise to lower the saw blade until the blade reaches
the desired depth as shown on the gauge pin.
5. Slowly push the cutter forward keeping the guide roller on the cutting line.
Stop Cutting
1. Turn the height adjust handle clockwise raise the saw blade off the ground.
2. If the engine has been running for a while and is hot, push the throttle lever fully away from the
operator to minimize the engine speed and allow the engine to idle for a few minutes to cool.
3. Set the engine switch to OFF.
4. Close the fuel valve on the engine.
