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 clothes to
remove dirt, dust, oil, grease, etc.
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
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 cordless pole chain saw 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
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.
Chain tensioned while warm, may be too tight upon cooling. Check the “cold tension” before
next use.
Chain Oiler
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.
Remove the cap and carefully pour approximately 2.54oz of bar and chain lubricant into the bar
lube reservoir.
Replace the cap and tighten securely.
Check and refill the bar lube reservoir every time the pole saw is used.
NOTE
:Do not use dirty, used, or otherwise contaminated lubricants. Damage may occur to the
oil pump, bar, or chain.
Chain Maintenance
For smooth and fast cutting, the chain needs to be maintained properly. The following
conditions indicate that the chain requires sharpening:
Wood chips are small and powdery.
Chain must be forced through the wood during cutting.
Chain cuts to one side. During maintenance of the chain, consider the following:
Improper filing angle of the side plate can increase the risk of a severe kickback.
Depth gauge (or raker clearance) setting determines the height the cutter enters the wood and
the size of the wood chip that is removed. Too much clearance increases the potential for
kickback. Too little clearance decreases the size of the wood chip thus decreasing the chain’s
cutting ability.
If cutter teeth have hit hard objects such as nails and stones, or have been abraded by mud or
sand on the wood, have service dealer sharpen chain.
