Setup
Check for Shipping Damage
Check the unit for any damage that may have occurred
in shipping. Notify the carrier immediately if there is
any damage.
Set Up
Charge the battery. Be sure the battery connections
are correct and secure. Connect the fuel line to the
engine using the quick coupler provided. Squeeze the
priming bulb 3 to 5 times. If you are using a downstream chemical injector, install it between the pump
unloader and the high pressure hose, using the quick
couplers provided.
Connect the high pressure hose between the pump
outlet and the gun inlet. Both of these connections are
made with quick couplers.
CAUTION
Up to 100 ft (30 m) of high pressure hose may
be used. Longer hoses may affect sprayer performance, and chemical injector performance, if used.
Install the appropriate spray tip on the wand. See
Installing and Changing Spray Tips. If you are using a
sandblaster kit, see its separate manual for installation
instructions.
Connect to Water Supply
CAUTION
Before attaching to the water supply, check your
local plumbing code regarding cross–connection to
the water supply. Use a backflow preventer if
required by local code.
Do not exceed 160_F (70_C) inlet water temperature.
Connect a hose with at least a 3/4 inch (19 mm) ID
from the water supply to the unit’s 3/4 inch garden
hose inlet. The supply hose should not be more than
50 ft (15 m) long.
NOTE: The water source at the unit must have a
minimum flow rate equal to that of the unit (see
Technical Data, inside back cover).

Operation
Pressure Relief Procedure
WARNING
INJECTION HAZARD
System pressure must be manually
relieved to prevent system from starting
or spraying accidentally. Fluid under high
pressure can be injected through skin and cause
serious injury. To reduce risk of injury from injection, splashing fluid, or moving parts, follow Pres-
sure Relief Procedure whenever you:
D are instructed to relieve pressure,
D stop spraying for more than 10 minutes,
D check or service system equipment,
D install or clean spray nozzle.
1. Engage trigger safety latch.
2. Turn sprayer off.
3. Remove ignition cable from spark plug.
4. Remove siphon tube from water supply.
NOTE: This pressure washer is equipped with a
low–oil sensor that shuts the engine off if the oil
level falls below a certain level. If the unit stops
unexpectedly, check both the oil and the fuel
levels. Check the oil level each time the unit is
refueled.
2. Check fuel level.
WARNING
FIRE HAZARD
Do not refuel a hot engine. Refueling a
hot engine could cause a fire. Use only
fresh, clean regular or unleaded gaso-
line. Close fuel shutoff valve during refueling.
3. Turn on the water supply.
CAUTION
Never run unit dry. Costly damage to pump will
result. Always be sure water supply is sufficient
before operating.
4. Trigger the gun until water sprays from the tip
indicating that the air is purged from the system.
5. Open the fuel shutoff valve. Be sure the spark plug
ignition cables are pushed firmly onto the spark
plugs. Put the ignition shutoff switch in the “on”
position and the throttle in the “run” position.
5. Disengage trigger safety latch and trigger gun to
relieve pressure. Engage trigger safety latch.
6. If spray tip or hose is completely clogged, or
pressure has not been fully relieved after following
steps above: Disengage trigger safety latch and
trigger gun to relieve pressure. Wrap rag around
hose end coupling and VERY SLOWLY loosen
coupling to relieve pressure gradually, then loosen
completely. Now clear tip or hose.
Startup
1. Check oil levels.
D Engine: Add SAE 30 or 10W–30 weight deter-
gent oil as necessary.
D Pump: Add SAE 20 or 30 weight non–deterg-
ent oil.
6. Start the engine.
NOTE: For easier starting, have one person start the
pressure washer while another person triggers
the spray gun.
If the engine is cold, completely close the engine
choke. Press the start button. In cool weather, the
choke may have to be kept closed for 10 to 30
seconds before opening it to keep the engine
running. Otherwise, open the choke as soon as the
engine starts.
If the engine is warm, leave the choke open or
partially closed. Start the engine as described in the
preceding paragraph. When the engine starts, be
sure to open the choke completely.
7. ALWAYS engage the gun’s trigger safety latch
whenever you stop spraying, even for a moment,
to reduce the risk of fluid injection or splashing in
the eyes or on the skin if the gun is bumped or
triggered accidentally.
8. ALWAYS observe the following CAUTIONS to
avoid costly damage to the pressure washer.
3085326
Operation
CAUTION
Pressure washer is equipped with a thermal relief
valve. If pressure washer is operated without
spraying for an extended period (approximately 10
minutes) the valve will expel hot water.
Do not operate pressure washer with inlet water
screen removed. Keep screen clean. Screen keeps
abrasive sediment out of pump, Abrasive sediment
can clog pump or damage cylinders.
Do not pump caustic materials; such materials may
corrode pump components.
9. See the chemical injector or sandblaster kit manual for detailed cleaning information if these accessories are used.
Trigger Safety Latch
WARNING

TRIGGER SAFETY LATCH SHOWN ENGAGED
Figure 2a
To reduce risk of serious bodily injury, including
fluid injection, splashing in eyes or on skin, always
engage trigger safety latch when spraying is
stopped, even for a moment. In engaged position,
trigger safety latch prevents gun from being triggered accidentally by hand or if dropped or
bumped. Be sure to push down latch fully to engage it. If latch not fully engaged, gun can accidentally trigger. See Figures 2a and 2b.
