MAINTENANCE

SPECIFIC MAINTENANCE

ENGINE: The engine instructions that accompany your unit detail specific procedures for maintenance of
the engine. Following the engine manufacturer's recommendations will extend the engine's life and ensure
the best possible performance.
PUMP: Change the pump oil after the first 50 hours of operation. After the initial change, every 3 months
or 250 hour intervals are recommended. If oil appears dirty or milky, changes may be required in greater
frequency. Use SAE 30 non-detergent pump oil and fill only to the center of the oil sight glass.
DO NOT overfill.
NOZZLE: Water flow through the spray nozzle will erode the orifice over time, making it larger. This will
result in a reduction of pressure. Nozzles should be replaced whenever pressure is less than 85% of the
maximum. The frequency of replacement will depend upon such variables as mineral content in the water
and number of hours the nozzle is used. Every 3-6 months tends to be a standard interval for replacement.
PRESSURE WASHER PUMP & COIL SAVER TOOL
This tool utilizes compressed air to clear any remaining water from the pump and hot water coil in your
pressure washer. To use the Pump & Coil Saver Tool, ensure your air compressor's regulator is set to a max
pressure of 60 PSI. Leave your hose and gun connected to your pressure washer, but remove the nozzle
from the end of the wand. For hot water pressure washers, it is recommended that all water be removed
from the pump and coil after every use. This will prolong their life and prevent possible freezing damage in
cold weather. Follow the steps below to use the Pump and Coil
Saver Tool:
1. Thread the blow out tool into the inlet of the pump
2. Ensure air compressor regulator is set to 60 PSI or less
3. Connect air line from air compressor to blow out tool
4. Hold trigger of pressure washer gun open
5. (If applicable) squeeze bypass hose several times to help remove water from the
unloader bypass system
6. Once there is no more water coming out of the tip of the gun, disconnect the
airline from the blow out tool, squeeze trigger of the pressure washer gun to relieve
any remaining air pressure
