CS-400 OPERATION
Do not let the tip of the bar
touch anything while the
engine is running. At cutting
speed the chain is moving at a
high rate of speed. Should the
tip contact a limb or log while
the chain is moving, the tip
will be pushed upward with
considerable force. This is
known as kickback. Avoid it!
In all circumstances the operation of the chain saw is a one-man job. It is
difficult at times to take care for your own safety, so don’t assume the
responsibility for a helper as well. After you have learned the basic techniques
of using the saw, your best aid will be your own good common sense.
The accepted way to hold the saw is to
stand to the left of the saw with your left
hand on the front handlebar and your
right hand on the rear handle so you can
operate the throttle trigger with your right
index finger. Before attempting to fell a
tree, cut some small logs or limbs.
Become thoroughly familiar with the
controls and the responses of the saw.
Start the engine, see that it is running
properly. Squeeze the trigger to open the
throttle wide open and start the cut. If the
chain is properly sharpened, the cutting
should be relatively effortless. It is not
necessary to press down hard to make
the saw cut. Pushing the saw too hard will
slow the engine and cutting will actually
be more difficult.
Sap from palm trees may corrode metal parts unless proper saw
maintenance is performed. Make sure to clean metal parts from palm
sap immediately after use.
Remove sprocket cover. Clean wood chips and sawdust from cover and
engine crankcase.
Never use metal tools for cleaning which may scratch the metal paint and
allow corrosion to develop.
Clean sap accumulation from metal parts with cloth and warm water with
soap.
