WARNING:
When servicing, use only identical replacement
parts. Use of any other parts could create a
hazard or cause product damage.
WARNING:
Always wear eye protection with side shields
marked to comply with ANSI Z87.1, along with
head protection. Failure to do so could result in
objects being thrown into your eyes and other
possible serious injuries.
WARNING:
Before inspecting, cleaning, or servicing the
unit, stop the motor, wait for all moving parts
to stop, and remove the battery pack. 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 could
result in serious personal injury.
All pole saw service, other than the items listed in
these maintenance instructions, should be per-
formed by competent pole saw service personnel.
(For example, if improper tool is used to hold the
flywheel in order to remove the clutch, structural
damage to the flywheel could occur and subse-
quently could cause the flywheel to burst).
CHAIN TENSION
See Figures 12 - 13.
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 protec-
tive gloves when performing maintenance to
the chain.
Stop the motor and remove the battery pack
before setting the chain tension. Make sure
the chain cover screw 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. 12.
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, as shown in
fig. 13.
FLATS
APPROX .050 in.
