WARNING
OVERSPEEDING
Do not operate machine at over 1450rpm.
Over speeding can cause serious pump damage.
EXCESSIVE BYPASS
Do not run on excessive bypass. Switch machine off within five minutes of ceasing operation as
excessive bypass can cause heat build-up in pump and subsequent damage. Excessive bypass
running voids warranty.
HIGH PRESSURE SETTING
The high pressure pump is factory set to operate at its rated pressure.
DO NOT ADJUST
. Tampering
with the pressure regulator will void warranty and can be
DANGEROUS
.
CHECK NOZZLE MONTHLY
If pressure drops off, check nozzle for wear. Nozzles should be replaced on a regular basis (every
month for machines in regular use, every three months for machines used intermittently). Using the
machine with the incorrect nozzle size or worn nozzle will void warranty and can be
DANGEROUS
to
the operator.
PRESSURE CLEANER DAILY CHECK LIST
IMPORTANT:
Check pump oil level (A).
.
NB.
Pump oil level should be level with the middle of the side oil plug or
sight glass. Do not overfill. If necessary, top up with SAE30W oil.
Do not mix different grades of oil as this may affect the machine’s
performance. If alternative oil is used, first empty out existing oil by
unscrewing drain plug in bottom of machine.
Check nozzle for wear.
Check all high pressure components for leaks:
(a) Gun/Lance. (b) HP hose. (c) All fittings.
Check water filter and clean if necessary.
Check unloader, safety valve and thermal dump for leaks.
Warning:
Ensure top mounted breather plug is kept clean. Blocked breather can result in pressurisation
of the oil chamber and blown seals.

involved should include the motor manufacturer’s recommendations (see separate Manual) and
the following:
Change pump oil
