Operation
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
D
Are instructed to relieve the pressure
D
Stop spraying for more than 10 minutes
D
Check or service any of the system equipment
D
Install or clean the spray nozzle
1. Engage the trigger safety latch.
2. Turn the engine off.
3. Pull the plug wire off the spark plug.
4. Shut off the water supply.
5. Disengage the trigger safety latch, and trigger the
gun to relieve pressure. Then engage the trigger
safety latch again.
If you suspect that the spray tip or hose is completely
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, and clear the tip or
hose.
WARNING
PRESSURE INDICATED ON GAUGE
The pressure gauge (shown in Fig. 1) indicates the
spraying pressure
when the gun is triggered and
the
bypass pressure
when the gun is not triggered.
Pressure at the gun may be significantly higher
than the bypass pressure indicated on the pressure
gauge. Therefore, always follow the
Pressure
Relief Procedure above regardless of the
pressure indicated on the gauge.
Operating Cautions
Always observe the following
CAUTIONS when
operating the pressure washer to avoid costly damage
to the pressure washer.
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 for 10 minutes.
If heated
inlet water is used, reduce this time further .
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
through the pump; such materials could corrode the
pump components. However, it is safe to pump
antifreeze through the pump for cold-weather
transport and storage.
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. In the
engaged position, 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 to prevent the gun from being
triggered. See Fig. 2.
