it. (See Figure 16)
Always engage the trigger safety latch when the unit is not in
use.

Operation
! IMPORTANT !
This pressure washer is equipped with a microswitch
sensitive to water flow. This Instant Start/Stop switch
(ISS) senses water flow in the pump. When the trigger is
released, water stops flowing through the pump. The ISS
then automatically turns the motor off to protect pump
from overheating.
OPERATION
1. Turn on water.
2. Pull trigger on gun.
3. Turn the "ON/OFF" switch to "ON".
4. Release trigger. The pressure washer motor will stop running.
5. To spray again, pull trigger and motor and pump will restart.
NOTE: Occasionally the motor may run for a short time
to bring fresh, cool water into the pump even if trigger is
released. This is part of normal operation and will not damage
the unit.
Always turn the "ON/OFF" switch to
"OFF" then trigger gun to release hose
pressure before unplugging power cord.
Risk of equipment damage. Always make
sure the "ON/OFF" switch on the unit is
"OFF" and unit is unplugged prior to storage.
Risk of Injection. Unit will start spraying
when trigger is squeezed if ON/OFF switch is
in "ON" position. Always point gun in safe direction.
SURFACE PREPARATION
The following cleaning procedure will help you organize your
cleaning task and ensures that you will achieve the best results in
the shortest amount of time. Gallons Per Minute (GPM), the more
water per minute can mean faster cleaning, especially when
washing off materials like mud and road tar. GROUND FAULT
CURRENT INTERRUPTER (GFCI) protects user from accidental
electrocution (for electric powered pressure washers only).

Trigger
Safety Lock
Remember to use the spraying / cleaning techniques mentioned
in the following section.
Before starting a pressure washer cleaning job, prepare the
surface you intend to clean. Clear furniture from the area and
make sure that all windows and doors are closed tightly. Also,
protect all plants and trees near the cleaning area with a drop
cloth. A covering ensures that your plants won't be sprayed by
the detergents.
START UP
ALWAYS use this start up procedure to ensure that the unit is
started safely and properly.
If water has frozen in the pressure washer,
thaw the pressure washer in a warm room
before starting. DO NOT pour hot water on or into the pump;
internal parts will be damaged. Check for leaks.
1. Ensure that the power switch is in the "OFF" position.
2. Attach a garden hose to the inlet side of the pump and
connect it to the water supply. Use a hose with an internal
diameter (I.D.) of 5/8 in. (1.58 cm) and a length of 50 ft. (15 m)
or less.
Some local plumbing codes require backfl ow
prevention when connecting to a fresh water
supply. Install a backfl ow preventer upstream from the pump if
necessary.
a. If inlet water pressure is over 100 psi, install a regulating
water valve at the garden hose connection.
b. Do not exceed 100˚ F (38˚ C) inlet water temperature.
NOTE: The inlet water supply must have a minimum flow rate of
5 gpm (19 lpm).
4. Turn the water supply ON.
Never run the unit dry. Be sure the water
supply is completely turned on before
operating the unit.
5. Trigger the gun until water sprays from the nozzle indicating
that all air is purged from the system. Set the trigger safety
latch.
6. Plug the power cord into a grounded 120V outlet, that is on a
dedicated circuit. Do not use extension cord. Press the reset
button on the GFCI plug adapter. This must be done each
time the unit is plugged into an outlet. (Figure 17)
SYSTEM CONNECTION
(See page 5 for Assembly Instructions)
1. Plug the power cord into a grounded 120V outlet.
2. Turn water on.
3. Unlock trigger lock by moving lock right to left.
4. Depress and hold the trigger on the gun for one minute to
release pressure and remove any air trapped in the system.
5. Turn the "ON/OFF" switch to the "ON" position.
