OPERATION

FILLING THE FUEL TANK

See Figure 2.

nClean the surface around the fuel cap to prevent con- tamination.

nLoosen the fuel cap slowly.

nCarefully pour the fuel mixture into the tank. Avoid spill- age.

nPrior to replacing the fuel cap, clean and inspect the gasket.

nImmediately replace the fuel cap and hand tighten. Wipe up any fuel spillage.

NOTE: It is normal for the engine to emit smoke during and after the first use.

ADDING BAR AND CHAIN OIL

See Figure 3.

Use HOMELITE Bar and Chain Oil. It is designed for chains and chain oilers, and is formulated to perform over a wide temperature range with no dilution required. Chain saw should use approximately one tank of oil per tank of fuel.

NOTE: Do not use dirty, used, or otherwise contaminated oils. Damage may occur to the oil pump, bar, or chain.

nCarefully pour the bar and chain oil into the oil tank.

nFill the oil tank every time you fuel the engine.

OPERATING THE CHAIN BRAKE

See Figures 4 - 5.

Check the operating condition of the chain brake prior to each use.

nUsing the back of your left hand, engage the chain brake by pushing the chain brake lever/hand guard toward the bar while the chain is rotating rapidly.

nReset the chain brake back into the RUN position by grasping the top of the chain brake lever/hand guard and pulling toward the front handle until you hear a click.

WARNING:

If the chain brake does not stop the chain immediately, or if the chain brake will not stay in the run position without assistance, take the saw to an authorized service center for repair prior to use.
