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 recomendations 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 200 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 (15) Approximately 7 oz. DO NOT OVERFILL!
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.)
NOZZLES:
Quick Connect, Adjustable & High/Low 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.
Adjustable Nozzle:
Nozzle orifices should be kept clean and free from obstructions.
Follow the procedures listed below to clean nozzle orifice: (See
WARNING, left.)
1.
Disconnect the wand from the gun.
2.
Insert the nozzle cleaner (supplied with the unit) into the
nozzle and rotate. (See drawing, left.)
3.
Flush the nozzle with water.
4.
Reconnect the wand and gun assembly.
5.
Turn the unit "ON". Point the gun in a safe direction and
trigger the gun to begin spraying. Adjust spray pattern
to 0°. If spray pattern is still distorted, repeat steps
1-4. If you are unable to thoroughly clean the nozzle
using this procedure, then the nozzle must be replaced.
To remove or replace adjustable nozzle:
1.
Insert a 2.0 mm allen wrench into the nozzle.
2.
Rotate the wrench counterclockwise to remove the nozzle.
3.
Inspect the nozzle and clean or replace before reinserting.
