See Product Manual for

General Safety Information

1. Slide handle over legs and secure

with bolts provided.

2. Insert removable spray tips and

rubber grommets into holes pro­vided on frame (if applicable).

3. Connect the clear plastic chemical

suction tube with filter to chemical
injector hose barb on the pump.

4. Connect the high-pressure hose to

the pump outlet.

5. Connect the high-pressure hose to

the gun.

6. Attach lance with nozzle to the

gun.

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 in a warm room
before starting. DO NOT pour hot
water on or into the pump; internal
parts will be damaged.

TRIGGER SAFETY LATCH

In the engaged position, the trigger
safety latch prevents the gun from
being triggered accidentally. Push
latch fully down to engage (See Figure

2). Always engage trigger safety latch
when unit is not in use.

1. Check oil levels. Add oil as necessary.
NOTE: Some units are equipped with a

low-oil sensor that shuts engine off if
oil level falls below a certain level. If
unit stops unexpectedly, check both oil
and fuel levels. Check oil level each
time unit is refueled.

2. Check fuel level.

DO NOT refuel a

hot engine.
Refueling a hot engine could cause a
fire. Use only fresh, clean regular or
unleaded gasoline. Close the fuel
shutoff valve during refueling.

3. Attach garden hose to inlet side of

pump and connect to water supply.
Hose should have an I.D. of 5/8” and
not be longer than 50 ft. (15 M).

back to step 7 and repeat until
engine starts.

1. Be sure all detergent is flushed
from system.

2. Turn off engine.

3. Turn off water supply.

4. After engine and water supply are
turned off, trigger the gun to
depressurize the system.

NEVER turn the

water supply off
before turning the engine off. Serious
damage could occur to the pump
and/or engine.

NEVER disconnect

the high pressure
discharge hose from the machine
while the system is pressurized. To
depressurize, turn engine off, turn
water supply off and squeeze gun
trigger 2-3 times.

5. After each use, wipe all surfaces of

the pressure washer with a clean,
damp cloth.

NOTE: A winterizing kit,
(PW104200AJ) is available for long
term storage.

Some local plumb-

ing codes require
backflow prevention when connecting
to a fresh water supply. Install back­flow preventer upstream from the
pump if necessary.

a. If inlet water pressure is over 100

psi (7 bar) a regulating water
valve must be installed 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 on the water supply.

Never run the unit

dry. BE SURE water
supply is completely turned on before
operating unit.

5. Trigger gun until water sprays from

onto spark plug. On units equipped
with an ignition shutoff switch, put
switch in the “ON” position and put
throttle in the “RUN” position.

7. Start engine.

If engine is cold, completely close
engine choke. Grasp starter rope,
brace one foot on chassis then pull
rope rapidly and firmly. Continue
holding rope as it returns. Pull and
return the rope until engine starts.
In cool weather, the choke may have
to be kept closed for 10 to 30 sec­onds to keep the engine running.
Otherwise, open choke as soon as
engine starts.

If engine is warm, leave choke open
or just partially closed. Start engine
then open choke completely.

Never let starter

rope return by
itself. This could jam the recoil system.
