WARNING
: Before inspecting, cleaning or servicing the unit, stop the motor, wait
for all moving parts to stop, and disconnect from power supply. Failure to follow these
instructions can result in serious personal injury or property damage.
General maintenance
Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to
damage from various types of commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, oil, grease, etc.
WARNING
: Do not at any time let brake fluids, gasoline, petroleum based
products, penetrating oils, etc., come in contact with plastic parts. Chemicals can
damage, weaken, or destroy plastic, which may result in serious personal injury.
All chain saw service, other than the items listed in the instruction manual maintenance
instructions, should be performed by competent chain saw service personnel.
Chain tension
WARNING:
To avoid possible serious injury, never touch or adjust the chain while
the motor is running. The saw chain is very sharp; always wear protective gloves when
performing maintenance to the chain. Stop the motor and disconnect from power
supply before setting the chain tension. Make sure the guide bar nut is loose to finger
tight, turn the chain tensioning screw clockwise to tension the chain. Refer to Replacing
the Bar and Chain for additional information.
NOTE:
A cold chain is correctly tensioned when there is no slack on the underside
of the guide bar, the chain is snug, but it can be turned by hand without binding.
Chain must be re-tensioned whenever the flats on the drive links hang out of the bar
groove as shown in Fig.10. During normal operation, the temperature of the chain will
increase. The drive links of a correctly tensioned warm chain will hang approximately
.050 in out of the bar groove.
NOTE:
New chain tends to stretch; check chain tension frequently and tension as
required.
CAUTION
: Chain tensioned while warm, may be too tight upon cooling. Check
the ‚cold tension“ before next use.
Chain oiler
Only use Premium Bar and Chain Lubricant. It is designed for chains and chain oilers
and is formulated to perform over a wide temperature range with no dilution required.
