WARNING
ELECTRIC SHOCK HAZARD
To reduce the risk of serious injury,
including electric shock, DO NOT touch
any moving parts or electrical parts with
your fingers or a tool while inspecting the repair.
Shut off the sprayer and unplug it as soon as you
complete the inspection. Reinstall all covers,
gaskets, screws and washers before operating the
sprayer.
3. If sprayer does not operate properly, review
repair procedure again to verify that everything
was done correctly. If necessary, see Trouble-
shooting Guide, pages 11 – 15, to help identify
other possible problems and solutions.
WARNING
EXPLOSION HAZARD
During operation, the motor and drive
housing become very hot and could burn
your skin if touched. Flammable materi-
als spilled on the hot, bare motor could cause a fire
or explosion. Always have the motor shield in place
during regular operation to reduce the risk of burns,
fire or explosion.
CAUTION
Do not run the sprayer dry for more than 30 seconds
to avoid damaging the pump packings.

of sprayer and replace if damaged. The cover
directs cooling air around the motor to help prevent
overheating. It can also help reduce the risk of
burns, fire or explosion; see preceding WARNING.
