3. Store all other parts so that they are pro-
tected from damage.
1. Keep dry in storage, avoid drastic tempera-
ture change.
2. Do not pile up the motors too high, this may
result in damage of package of the motors at
bottom.
3. Avoid up side down or incline of motor in
storage and transportation.
STORAGE PROCEDURE
Water should not remain in the unit for long
periods of time. Sediments or minerals can
deposit on pump parts and "freeze" pump
action. If you do not plan to use the pressure
washer for more than 30 days, follow this pro-
cedure:
1. Flush chemical injection hose by placing
filter into a pail of clean water while running
pressure washer in low pressure mode. Flush
for one to two minutes.
2. Remove high pressure and garden hoses,
then run the motor for 10 seconds to discharge
the water that remain in the pump.
4. Ensure pump is clean and empty to prevent
corrosion build up and freezing of pump com-
ponents.
5. Store unit in a clean, dry area.

the minimum required: Check the mains power
supply is adequate.
The pump is stuck or frozen: Check by turning
the motor manually as described in instruc-
