OPERATING INSTRUCTIONS
PRIMING THE PUMP:
1. It is essential to prime the pump on initial start-up and each time the water
supply is disconnected from the unit after initial use.
2. Lay the high pressure hose out to remove any loops. Water ow will constrict
the hose, creating tight loops if the hose is not straight.
3. Securely connect the gun assembly to the high pressure hose.
NOTE: The nozzle should NOT be connected to the gun assembly at this time.
See "Nozzle Connection" pg. 14.
4. With the trigger gun locked in the "OFF" position, turn the water supply
completely on. Pointing the gun in a safe direction, unlock the trigger gun
and squeeze the trigger.
5. Low pressure water will begin owing from the hose/gun assembly. This
allows the unit to prime and purge any air from the system. The unit is
primed when water ow is uninterrupted by air.
6. Once the unit is primed, release the trigger and lock the gun in the "OFF"
position. Securely connect the nozzle assy. (See "Nozzle Connection" pg.
14.)
START-UP:
1. Refer to the "Safety Precautions" pgs. 4-7 before starting the unit.
2. Locate the Safety Decals on your unit and heed their warnings.
3. With the gun locked in the "OFF" position, point the trigger gun away from
yourself or anyone else. Ensure water supply is turned completely on.
4. Disengage the safety lock-off on the gun and squeeze the trigger. Low
pressure water will begin owing from the nozzle.
5. Before starting the unit, brace yourself as the gun will kickback from the
high pressure created by the pump once the unit has started.
6. Move the switch to the "ON" position. This switch includes a circuit breaker
for protection of the motor. In case of excess load, the circuit breaker will
automatically move the switch to the "OFF" position. To restart, move the
On/Off Switch to the "ON" position again.
7. Once the unit is turned on, perform the following procedures with the gun
open:
a. Inspect for system water leaks and oil leaks. If a leak is found, TURN
UNIT OFF IMMEDIATELY! Be sure that all damaged parts are replaced
and that the mechanical problems are corrected prior to operation of
the unit. If you require service, contact Mi-T-M Customer Service.
b. Inspect high pressure hose for kinking cuts and leaks. If a cut or leak is
found, DO NOT TOUCH HOSE AT CUT OR LEAK!!! TURN UNIT OFF
IMMEDIATELY! Replace hose before restarting the unit. Be sure that
all damaged parts are replaced and that the mechanical problems are
corrected prior to operation of the unit. If you require service, contact
Mi-T-M Service.
c. Inspect electrical cord for cuts. If a cut is found, DO NOT TOUCH OR
USE ELECTRICAL CORD! Replace cord before starting the unit.
8. Trigger the gun several times. Be certain to LOCK the trigger gun in the
"OFF" position whenever changing the nozzle. NEVER look directly into
the nozzle! High pressure water creates a risk of severe injury!
9. Do not allow unit to operate in bypass mode (with trigger closed) for more
than three minutes without triggering the gun. Failure to follow this simple
rule can cause premature failure of pump packing seals, resulting in costly
pump repair.
10. Because your pressure washer delivers a high pressure spray and a variety
of spray patterns, there are many cleaning jobs that can be done without
the use of detergents. If a cleaning agent is required, see "Cleaning With
Detergents" pg. 17 for the correct procedures.
