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 release any kinks. Water flow 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 assembly should NOT be connected to the gun assembly at
this time. (See "Trigger Gun", pg. 11)
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 flowing from the hose/gun assembly. This allows
the unit to prime and purge any air from the system. The unit is primed when
water flow 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 assembly. (See "Trigger Gun", pg. 11)

START-UP:

1. Refer to the "Safety Precautions" pgs. 4-7 before starting the unit.
2. Find the Safety Decals on your unit and heed the warnings. (8, 9, 12 & 15)
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 flowing from the nozzle. Before starting the unit, brace yourself
as the gun will kickback from the high pressure created by the pump once the
unit has started.
5. Move the On/Off 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.
6. Once the unit is turned on, perform the following procedures:
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 Nilfisk-Advance Customer Service.
b. Inspect high pressure hose and electrical cord for kinking, cuts or leaks.
If a cut or leak is found, DO NOT TOUCH HOSE OR CORD AT CUT OR
LEAK!!! TURN UNIT OFF IMMEDIATELY! Replace hose or cord before
SPRAY
restarting the unit. See "Miscellaneous Safety Precautions #6,pg. 6. 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
Nilfisk-Advance Customer Service.
7. Trigger the gun several times and try adjusting the spray pattern. Be certain
to LOCK the trigger gun in the "OFF" position whenever moving the adjustable
nozzle. NEVER look directly into the nozzle! High pressure water creates a
risk of severe injury!
8. 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.
9. 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. 15 for the correct procedures.
