Mi-T-M CD-1002/1502-3MUH/3MUH1 Operator's Manual
SPECIFIC MAINTENANCE:
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 OVERFILL!
NOZZLES: Nozzle
orifices
should be kept clean and free of obstructions. If
the nozzle becomes clogged, the pump pressure will increase.
Therefore, should the nozzle become clogged, the nozzle orifice
must be cleaned immediately. Follow the procedure listed below
to clean nozzle orifice: (See
WARNING
, left.)
1. Disconnect the wand from the gun.
2. Insert the nozzle cleaner (supplied with unit) into the nozzle and
rotate.
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 (supplied with the unit) into the
nozzle.
2. Rotate the wrench counterclockwise to remove the nozzle.
3. Inspect the nozzle and clean or replace before re-inserting.
WINTERIZING:
For storage and transportation purposes in subfreezing ambient temperatures,
it will be necessary to winterize this unit. This unit must be protected to the
lowest incurred temperature for the following reasons:
1. If any part of the pumping system becomes frozen; excessive pressure may
build up in the unit which could cause the unit to burst resulting in possible
serious injury to the operator or bystanders.
2. The pumping system in this unit may be permanently damaged if frozen.
FREEZE DAMAGE IS NOT COVERED BY WARRANTY.
If you must store your unit in an area where the temperature may fall below 32°F,
you can protect your unit by following the procedure outlined below.
1. Gather the following items:
a. Two 5 gallon containers.
b. One gallon of antifreeze. (Mi-T-M recommends an environmentally safe
antifreeze.)
c. Water supply.
d. Three foot hose, 1/2-3/4 I.D. with a 3/4 inch male garden hose fitting.
2. Procedure:
a. To start winterizing, unit must be run and primed according to the "Start-
up Procedures" listed on page 14.
b. After running and priming, shut off the unit and water supply.
c. Relieve system pressure by pointing the trigger gun in a safe direction
and squeezing the trigger until water flow ceases to exit the nozzle.
d. Lock the trigger gun in an OFF position and remove the nozzle.
e. Remove the water supply hose from the unit and attach the 3 foot hose
securely to the inlet connection.
f. Shut off the detergent injector if applicable.
g. Fill one 5 gallon bucket with water.
