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 can 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 can
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.
Felling The Tree
A falling tree can seriously damage anything it may hit - a car, a
house, a fence, a power line, or another tree. There are ways to
make a tree fall where you want it, so first decide where that is!
