General Maintenance; Nozzle Maintenance - Milwaukee 4555-22 Manual Del Operador

When servicing, use only identical replacement
parts. Use of any other parts may create a hazard
or cause product changes.
To reduce the risk of injury, always shut off engine
and relieve system pressure before performing any
maintenance. Never disassemble the machine.

GENERAL MAINTENANCE

NOTE: The Honda GX390 engine has a separate warranty
found in the engine manual (included with this product).
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.
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.
Never 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 per-
sonal injury.
