WARNING
ALWAYS use this start up procedure to
ensure that the unit is started safely
and properly.
If water has
frozen in the pres-
sure 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).

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.

WARNING
!
CAUTION
Some local plumb-
ing codes require
backflow prevention when connecting
to a fresh water supply. Install back-
flow 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 gar-
den 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
tip indicating all air is purged from

6. Open fuel shutoff valve (if unit is
equipped with valve). Be sure spark
plug ignition cable is pushed firmly
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 sec-
onds 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.
