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.
