Portable Pressure Washer
If you must store your pressure washer in a location where the temperature is below
freezing, you can minimise the chance of damage to your washer with the following
instructions.
1. Shut off the water supply and relieve pressure in the spray gun by depressing the
trigger. Disconnect the garden hose from the pressure washer, but leave the high
pressure hose connected.
2. Tip the unit on its side with the inlet connection pointing up.
3. Insert a small funnel (to prevent spilling) into the inlet and pour in approximately
1/4 cut of RV antifreeze.
4. Disconnect spark plug wire.
Prior to restarting, thaw out any possible ice from the pressure washer hoses, spray
gun and wand.
Another method of reducing the risk of freeze damage is to drain your pressure
washer as follows:
1. Stop the pressure washer and detach the supply hose and the high pressure hose.
Squeeze the trigger of the discharge gun to drain all water from the wand
and hose
2. Restart the pressure washer and let it run briefly (about 5 seconds) until water no
longer discharges from the high pressure outlet.
When the pressure washer is not being operated or is being stored more than one
month, it is recommended that you turn off and disconnect the power supply and
rotate the motor by hand several times so as to avoid excessive current draw on the
motor and power supply.
