STORAGE & MAINTENANCE
SPECIFIC 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. Use Mi-T-M pump oil AW-
4085-0016 and fill only to the center of the oil sight glass. DO NOT OVER-
FILL!
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.)
BELT TENSION ADJUSTMENT: To maintain peak performance of your
pressure washer, it may be necessary to adjust the belt tension on occasion.
Follow the procedure outlined below.
1. Remove the belt guard and loosen the four bolts on the pump
(Reference A).
2. Turn the cap screw (Reference B) clockwise until a 1/2 inch belt deflection
is noticed between the pulleys.
3. Tighten the bolts. (Reference A)
4. Put a straight edge across both pulleys. If necessary, loosen one set of
pulley screws and adjust in or out to properly align. Tighten the pulley
screws and check the tension again.
5. Replace the beltguard and tighten the fasteners securely.
