This manual contains information that
is very important to know and understand. This information is provided for
SAFETY and to PREVENT EQUIPMENT
PROBLEMS. To help recognize this information, observe the following symbols.
Danger indicates
an imminently
hazardous situation which, if not
avoided, WILL result in death or serious injury.
Warning indicates
a potentially hazardous situation which, if not avoided,
COULD result in death or serious
injury.
Caution indicates
a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate
injury.
Notice
indicates important information, that if not followed,
may cause damage to equipment.
Remove the equipment and all parts
from the carton. The carton should
contain the following:
One (1) Pressure washer (pump,
engine, cart base)
One (1) Cart handle Assembly
One (1) Basket (not included with
all models)
One (1) Spray gun
One (1) Lance with nozzle
Five (5) Spray tips (not included
with all models)
One (1) High pressure hose
One (1) Pack of nuts, bolts,
manuals and Chemical Suction
Tube with Filter
If any parts are missing, DO NOT
return unit to the retailer. Know
model number (located on serial number tag on frame) and call 1-800-3300712 for replacement.
After unpacking the product, inspect
carefully for any damage that may
have occurred during transit. Make
sure to tighten fittings, bolts, etc.,
before putting unit into service.
Do not operate
unit if damaged
during shipping, handling or use.
Damage could result in bursting and
cause injury or property damage.
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).

up in the high pressure hose. Go
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.
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
tip indicating all air is purged from
system. Set trigger safety latch.
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 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.
8. If engine does not start after 2-3
pulls, squeeze the gun trigger to
release the pressure that has built
