TIPS FOR EXTENDING THE LIFE OF
YOUR PRESSURE WASHER
1. Never operate the unit without water.
2. Your pressure washer is not meant to
pump hot water. Never connect your
pressure washer to a hot water supply
as it will significantly reduce the life of
the pump.
3. Running the unit for more than one
minute without spraying water causes
heat to build up in the pump.
Running the unit without spraying
water can damage pump components.
Maintenance
Observe regular maintenance intervals to
ensure maximum performance and life
from the pressure washer. Refer to the
schedule for recommended maintenance.
If you operate the pressure washer in
dusty conditions, perform maintenance
checks more often.
ENGINE OIL CHANGING INSTRUCTIONS

engine or equipment
to drain oil, drain fuel from the fuel tank.

the spark plug.
2. Locate and remove the engine oil
drain plug (See Figure 15).
3. Drain old oil.
