Pressure Relief
Procedure
WARNING
INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you
DAre instructed to relieve the pressure
DStop spraying for more than 10 minutes
DCheck or service any of the system equipment
DInstall or clean the spray nozzle
1. Engage the gun trigger safety latch.
2. Turn the sprayer off, and remove the ignition cable
from the spark plug.
3. Shut off the water supply.
4. Disengage the trigger safety latch, and trigger the
gun to relieve pressure. Then engage the trigger
safety latch.
If you suspect that the spray tip or hose is clogged or
that pressure has not been fully relieved after following
the steps above: Disengage the trigger safety latch,
and trigger the gun to relieve pressure. Wrap a rag
around the hose end coupling, and VERY SLOWLY
loosen the coupling to relieve pressure gradually. Then
loosen it completely. Then clear the tip or hose.

4824111
Operation
Startup
Always use this start-up procedure to ensure that the pressure washer is started safely and properly.
DAlways engage the gun trigger safety latch when
you stop spraying even for a moment. This reduces
the risk of fluid injection or splashing in the eyes or
on the skin if the gun is bumped or triggered
accidentally.
DAlways observe the CAUTIONS in this section to
avoid costly damage to the pressure washer.
DIf you use the Sandblaster Kit, see the Sandblaster
Kit manual for detailed cleaning information.
1. Check the oil level.
NOTE: All pressure washers are equipped with a
low-oil sensor that shuts the engine off if the oil
level falls below a certain level. If the engine stops
unexpectedly, check both the oil and the fuel
levels. Check the oil level each time you refuel.
2. Check the 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 gasoline. Close
the fuel shutoff valve during refueling.
3. Turn on the water supply.
CAUTION
Never run the pressure washer without water.
Costly damage to the pump will result. Always be
sure the water supply is completely turned on
before you run the pressure washer.
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 cable is pushed firmly onto the spark plug.
Put the switch in the START position, and put the
throttle in the RUN position.
CAUTION
Do not allow the pressure washer to idle for more
than 10 minutes. Doing so could cause the
recirculating water to overheat and seriously
damage the pump. Turn off the pressure washer if
it will not be spraying at least every 10 minutes. If
heated inlet water is used, reduce this time more.
Do not operate the pressure washer with the inlet
water screen removed. The screen helps keep
abrasive sediment out of the pump, which could
clog the pump or damage the cylinders. Keep the
screen clean. Do not pump caustic materials; such
materials could corrode the pump components.
6. Pull the starter rope to start the engine. Brace one
foot on the pressure washer chassis, and pull the
starter rope out quickly. Pull and return the rope
until the engine starts.
CAUTION
Do not allow the starter rope to snap back against
the engine. Let the rope recoil gently to prevent
damage to the recoil.
NOTE: For easier starting, have one person start
the pressure washer while another person triggers
the gun.
If the engine is cold, start the engine with the
choke completely closed. In cool weather, you
might have to let the engine run with the choke
closed for the first 10 to 30 seconds. In warm
weather, open the choke completely as soon as
the engine starts.
If the engine is warm, start the engine with the
choke completely open or partially closed. When
the engine starts, open the choke completely.

Operation
Trigger Safety Latch
WARNING
To reduce the risk of serious bodily injury, including
fluid injection and splashing in the eyes or on the
skin, always engage the trigger safety latch when
you stop spraying even for a moment. When
engaged, the trigger safety latch prevents the gun
from being triggered accidentally by hand or if it is
dropped or bumped. Be sure the latch is pushed
fully down, or it will not prevent the gun from being
triggered. See Fig. 1.
Fig. 1

Trigger Safety Latch
Chemical Injector Operation
1. Relieve the pressure.
See page 3.
2. Insert the chemical filter (attached with clear tubing
to the chemical injector) into the container of
chemical.
3. Install the black large-orifice chemical tip. See
Installing and Changing Spray Tips at right.
This causes a drop in pressure that actuates the
chemical injector. Changing back to a small diameter
spray tip deactivates the chemical injector and
produces high pressure for rinsing. The chemical filter
can be left in the chemical container during high
pressure use. To regulate the flow rate of the chemical,
turn the chemical adjustment knob on the injector.
Maximum chemical flow is a full two turns
counterclockwise from the CLOSED (clockwise)
position.
Installing and Changing Spray Tips
Spray tips have 4- or 5-digit numbers on them. The
first two digits are the spray angle. Select the spray tip
appropriate for your application. Tip holding holes are
provided on the chassis.
Spray Tip Number Spray Pattern Fan Angle
00XXX 0_blaster (red)
15XXX 15_(yellow)
25XXX 25_(green)
40XXX 40_(white)
NOTE: The chemical injector tip is brass and has a
large opening and a black plastic cap.
1. Relieve the pressure.
See page 3.
2. Point the gun and wand away from yourself and
anyone else.
3. Without holding your hand over the spray tip (A),
pull back the quick coupler ring (B). Remove the
current tip and/or install a different one, and then
push back the ring. See Fig. 2.
4. Pull on the tip to be sure it is secure before you
spray again.
CAUTION
To avoid blowing the O-ring out of the quick coupler
due to the high pressure in the system, never
operate the pressure washer without a tip securely
mounted in the quick coupler.
