STORAGE & MAINTENANCE
ENGINE: The engine instructions that accompany your unit detail specific
procedures for maintenance of the engine. Following the engine manufac-
turer's recommendations will extend engine work life.
PUMP: The pump oil must be changed after the first 25 hours of operation.
Once the initial oil change has been completed, it is recommended the oil
be changed every 3 months or 250 hour intervals. If oil appears dirty or
milky, changes may be required at a greater frequency. Add pump oil and fill
only to the center of the sight glass (Refer to the parts listing for the correct
pump oil). DO NOT OVERFILL!
NOZZLES: Water flow through the spray nozzle will erode the orifice, mak-
ing it larger, resulting in a pressure loss. Nozzles should be replaced when-
ever pressure is less than 85% of the maximum. The frequency of replace-
ment will depend upon such variables as mineral content in the water and
number of hours the nozzle is used.
QUICK COUPLERS: There is an o-ring seal inside the female quick coupler.
This o-ring will deteriorate or, if the unit is allowed to pump without the high
pressure hose or nozzle attached, the o-ring may be blown out occasionally.
Simply insert a replacement o-ring to correct the leak. (Additional o-rings
can be purchased from your dealer.)
