PUMP MAINTENANCE

PUMP: Change the pump oil after the first 50 hours of operation. After the initial change, every
12 months or 500 hour intervals are recommended. If oil appears dirty or milky, changes may be
required in greater frequency. Use SAE 30W non-detergent pump oil and fill only to the center of
the oil sight glass. DO NOT overfill.
Oil Condition

Then Change after
If oil is milky in color, then water has leaked into the crankcase. Further inspections will be needed,
including pump seals and ceramics plungers.
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.
HEATER COIL: After every use flush with cold water to cool the coils down. Then flush out all the
water with the coil saver tool as described on Page 19. This will minimize scale build up.
Scale build-up in the coil results when the water is 'hard', which means it has calcium, magnesium
and other dissolved minerals. The heating and cooling process of will cause these minerals to
solidfy and bind to the inside of the coils. Left too long, the minerals will turn to scale and restrict
water flow. Excessive scale build up will need to be removed with a coil cleaner solution.
Do not expose to rain or excessive moisture.
HOSES AND SPRAY WAND: Drain of water after every use. Store in a safe, dry location.
FITTINGS: Inspect for leaks and damage. Replace parts as needed.
