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.
• Rinse with clean water and dry metal surfaces.
• Apply a light coating of engine or bar and chain oil to metal parts after
they are cleaned.
• Install and properly tension guide bar and chain. Run engine for one
minute alternating engine speed between full throttle for 5 seconds and
idle for 5 seconds to coat metal parts with additional protective chain oil.
◆ Do not run a chainsaw not under cutting load at wide open
throttle longer than 5 seconds or engine damage may
occur.
◆ Keep chain properly tensioned during operation to prevent
the chain from jumping out of the guide bar rail slot and
damaging metal engine parts.
