removing accessories, before adjusting
or changing set-ups or when making
repairs. Be sure the trigger switch is in
the OFF position. An accidental start-up

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.
LUBRICATION
All of the bearings in this tool are lubricated with a
sufficient amount of high grade lubricant for the life
of the unit under normal operating conditions.
Therefore, no further lubrication is required.
