storage & maintenance
specific maintenance:
pump:
Change the pump oil after the first 25 hours of operation. After 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 Mi-T-M pump oil (#AW-4085-006)
and fill only to
the center of the oil sight glass.
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 attached, it may be blown out occasionally.
Simply insert a replacement o-ring to correct the leak. (New o-rings
can be purchased from your dealer.)
nozzles:
Water flow through the quick-connect 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.
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.
. Remove the belt guard and loosen the two nuts on each side
of the pump. (Reference A) There are a total of 4 nuts.
2. Turn the cap screw (Reference B) clockwise until a 1/2 inch belt
deflection is noticed between the pulleys.
. Tighten the side nuts. (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.
