RAPTOR MANUAL - HIGH PRESSURE CLEANER
the throttle to the full open position. Allow the engine
to warm up. Release the trigger soon after the engine
starts.
7. With the wand pointed in a safe direction, squeeze
the wash wand trigger. If applicable; turn the unloader
valve while monitoring the pressure gauge to adjust
the pressure as desired. Do not exceed the machine
pressure rating. Release the wash wand trigger.
8. (If Applicable) Apply choke before starting.
9. Proceed to start engine (note may need to hold trigger
gun open during pull start).
10. Open the water control valve (high pressure gun).
Following the starting instructions supplied in the
engine operator manual, start the engine. Set the
throttle to the full open position (If Applicable). Confirm
that water flows freely through the nozzle. Close the
trigger on the high pressure gun. When the water
control valve is closed and the unit is running, the
unloader valve will recirculate water back to the pump
head or tank (If Applicable). Allow the engine to warm
up.
11. If needed, turn the unloader valve while monitoring
the pressure gauge on the unloader valve to adjust
the pressure as desired (If Applicable) (clockwise to
increase pressure, counter-clockwise to decrease
pressure). Do not exceed the machine pressure rating.
Do not force the unloader valve or use wrenches or
tools to turn. This will damage the unloader valve.
If the unit will not generate the rated pressure or is erratic
• Ensure that all in one vario nozzle head is clipped into
high pressure position.
• Make sure the engine throttle is properly adjusted to
the full open position.
• Turn unloader valve clockwise to increase pressure. Do
not force.
• Inspect system for leaks. Use caution during inspection
to prevent injury. If leaks are found, shut unit OFF
before fixing.
• Turn the unit OFF. Check the inlet hose and filter and
make sure that they clear of debris.
• Make sure there is adequate water flow to the unit.
• Turn the unit OFF. Remove the nozzle and clean the
orifices with the nozzle cleaning tool.
• Ensure correct nozzle orifice size is used and no signs
of excessive wear are evident.
• Activate trigger and run the unit to remove air or debris
from the system. Turn the unit OFF before removing or
attaching the lance/nozzle.
6. Assume a proper operating position.
• Be sure you can control the ON/OFF action of a water
control valve. Do not turn the valve ON yet. In case of
emergency you must be able to turn off water flow.
• Be sure that you have good balance and do not have
to overreach.
• You must be able to place one hand on the gun at all
times to control and support the lance.
This operating position will help to maintain control of the
gun and lance.
Pressure Washer operation
1. When using as a pressure washer use both hands
to grip and direct the wash wand for greater control.
Never direct the wash wand at people. High pressure
fluid can inject under skin resulting in serious injury.
Never direct wash wand at electrical equipment or
wiring to reduce the risk of electrical shock.
2. Control the flow of water with the trigger. Use care
when using the pressure washer. Holding the nozzle
too close to a surface can damage it. Test a small,
inconspicuous area to confirm the settings work as
desired.
3. Do not allow the jetter to run for extended period of
time with the trigger OFF. When the trigger is OFF,
water recirculates and it causes the water to heat up.
4. Once pressure washing is complete, release the trigger
and turn OFF the engine as directed in the engine
manual. Squeeze the trigger and ensure all water
control valves are also in open position to release
system pressure. Never leave the system pressurized.
Machine Shut Down Procedure
1. When high pressure cleaning task is complete, release
high pressure trigger.
2. Return to the unit controls.
3. Idle down unit RPMs via throttle control (if applicable)
4. Proceed to power down the engine via kill switch or
key switch (if applicable). Refer to engine operator
manual.
5. Turn water supply OFF.
6. Release system back pressure by pressing the trigger
on the spray gun (if applicable).
7. Disconnect high and low pressure hoses and coil the
assembly for safety and proper storage.
