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 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 could
result in serious personal injury.
Only the parts shown on the parts list are intended
to be repaired or replaced by the customer. All
other parts should be replaced at an Authorized
Service Center.

WARNING:
To avoid possible serious injury, never touch or

tive gloves when performing maintenance to
the chain.
