being sprayed immediately, leading to unexpected
accidents.
Do not point the nozzle at people or animals.
Failure to observe this may result in injury.

Set the switch to “OFF” immediately if the hose becomes
detached from the faucet or washer, and if water is no
longer being fed to the washer.
Failure to observe this may result in immediate
malfunctions (dry operations.)
Set the switch to “OFF” without fail when temporarily
suspending operations.
Failure to observe this may result in the motor

Commence initial washing approximately 2 to 3 meters
away from the targeted item, and then move gradually
closer while checking the level of cleaning until you reach
a distance in which soiling is e ectively washed away.
The pressure of the spray from the washer is
approximately 20-times greater than tap water. High-
pressure water jets may therefore damage or peel the
coating from the items being washed.
There are cases when the water spray will appear
unstable owing to the fact that air that has built up in
the pump and hose is purged together with the water
immediately after use. In this event, allow the water to
ow out until it stabilizes.
Leave two or more seconds gap between pulling and
releasing the trigger.
Failure to observe this may result in the pressure switch
malfunctions.
Do not use the washer for more than thirty consecutive
minutes without giving it a break.

amount of water from the nozzle with just the pressure
from the tap water. Check to make sure that no water is
leaking.

Do not switch the washer on with the faucet turned o .
Failure to observe this may result in malfunctions.
2. Set the switch to the “ON” position (Fig. 21)

Hold the trigger gun rmly in both hands, point the nozzle
at the item to be washed, and then pull the trigger.
The high-pressure water jet will spray out.
