OPERATING
Starting
Start the engine
• Open the fuel valve.
• Raise the blade by pushing down on the handle bar with
both hands to the full and locked position.
• Turn the switch to the 'ON” ('1” position) to start the
engine. The blade starts to rotate when the engine is
turned on.
• Move the speed lever 1/3 of the way to the open position.
• Close the engine choke lever.
The closed choke position enriches the fuel mixture for
starting a cold engine.
The open choke position provides the correct fuel mixture
for operation after the engine starts and for restarting a
warm engine.
• Pull the starter handle.
• After the engine starts, slowly open the choke. Allow the
engine to warm for a few minutes.
Start cutting
• Open the engine throttle lever to full open position for
maximum engine speed.
• Line up the saw with the cut line using the white wheel on
the front guide and the triangle pointer on the back of the
blade block.
• Push down on the saw handle and pull the blade release
lever to lower the blade in the concrete slowly.
• Push the saw forward to cut keeping the front guide wheel
in the cut line.
• Push the saw at about half speed for the first 50 feet to
allow the blade to develop good diamond exposure.
• Increase the forward speed of the saw until the blade and
engine are working at maximum efficiency. Do not force
the saw.
• When approaching a wall, raise the front guide and use
the triangle guide at the back of the blade block to cut the
last few feet.
• Do not hit the blade block assembly against any object.
Damage may result.
Stopping
• Raise the blade by pushing down on the handle bar with
both hands to the full and locked position.
• Move the engine throttle lever to the full closed position.
• Turn the switch to the 'OFF” ('O” position).
• Close the fuel valve.
• Clean the machine.
