STORAGE & 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 engine work life.
PUMP:
The pump oil must be changed after the first 25 hours of operation.
Once the initial oil change hasbeen 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. Use Mi-T-M pump oil #AW-4085-0016 and fill only to
the center of the oil sight glass. DO NOT OVERFILL!
NOZZLES: Water flow through the spray nozzle will erode the orifice,
making it larger, resulting in a pressure loss. 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.
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.)
