Overheat Thermal Protection

If the temperature of the motor gets too high, the thermal protection will shut the motor down. The switch

must be first shut off and then restarted. When this happens, do not immediately start cutting after restarting

the motor. Always run the machine at no load for a few minutes to return to a normal operating temperature

before continuing.

CAUTION: The motor will be damaged if it is repeatedly overloaded or overheated. Always cool the

motor by running at no load for a few minutes whenever it stops from either overheat or overload.

LEVELS

There are two spirit levels on the tool which allow the operator to align

the tool in the vertical and horizontal planes

OPERATION

Before operating, first check for:

• Proper chain tension and ensure guide bar nuts are tight

• Good condition of the chain, guide bar, and drive sprocket

• Connect the water supply, check for leaks and for proper water flow to the chain

• Ensure all safety equipment is in place and functioning normally

• Mark the line of cut before beginning.

WARNING: A new operator should perform some practice cuts under controlled conditions to become

familiarized with concrete chain saw techniques. Experience with a wood cutting chain saw does NOT

qualify an operator to use a concrete chain saw.

WARNING: Position the power supply cord so that it will not become caught on worksite obstacles.

CAUTION: Do not attempt to enter a kerf which is narrower than the chain. This will damage the

diamond segments.

CAUTION: Avoid the chain being pinched in the kerf. Plan the cut, and support the workpiece if

necessary, to avoid the keft closing down on the chain as cutting progresses.

NOTE: When cutting concrete with embedded rebar, always cut in such a way that the chain is cutting

both concrete and rebar at the same time. The concrete will help to keep the diamond segments sharp.

Begin the cut with the nose of the guide bar:

When beginning the cut, start with the nose of the guide bar, since the nose contains a sprocket, which

will offer the minimum friction for the chain. Since there is less water flow into the kerf with the nose of

the bar, the remainder of the cut should be performed by cutting with the guide bar fully plunged into

the kerf.
