[7] Unloader valve
This device is used to adjust pressure. If the water jet has been stopped during the operation, the pump
pressure (load) is reduced. Even after reducing the pressure (load) of the pump, high-pressure water is
sealed in the high-pressure hose, and spray gun. The unloader valve also serves as a safety valve.
Caution
 Do not adjust the pressure as it has been adjusted at the factory. It may cause breakdown.
 Tightening the adjusting screw of the unloader beyond the adjustable range may disable its
function as a safety valve and create dangerous situations. Do not forcibly tighten to screw of the
unloader valve.
[8] Water drain/air bleeder knob
When starting the machine, use this knob to bleed air from the water suction hose and pump to facilitate
suctioning water. Keep the knob open when the machine is restarted after a period of suspending
operation, as it makes easier to start the engine.
Use the knob to drain water before storing the machine.
Caution
 Be sure to close the knob once the engine has started. Failure to do so may cause the pressure
does not increase due to water leakage.

or burns.
 Do not tilt the machine more than necessary or take your hands off the machine while moving.
The machine may tip over and cause injuries.
[12] Speed control lever
