permifted pressure of the machine.
A large pressure control knob is fitted to the pump head. Under normal usage this
will not require any adjustment. We strongly recomment that pressure adjustments
are always made at the high pressure lance. as previously explained.
Also do not make any adjustment to the engine in an attempt to create higher
pressure, otherwise serious damage may occur.
CHEMICAL INJECTION
To improve the cleaning affect of the machine, it is possible to inject chemical
cleaning agents into the spray, but only when it is working at the low pressure
setting. This makes the machine particularly useful for washing away the traffic
film from vehicles, cleaning greasy engine parts and removing oil and grease
from concrete and other surfaces.
The chemical solution should always be applied first and allowed sufficient time
to react, before finally being cleaned off with a high pressure jet. Connect the
polythene detergent tube (Item 13) to the chemical inlet port which can be found
next to the high pressure outlet on the power washer pump. Fit the chemical/
detergent filter to the other end of the tube and then imerse this into the cleaning
agent. With the machine running normally, and the vario nozzle set to low pressure
spray (INJECTION) chemical will be drawn up and mixed with the water.
The brass ring on the chemical inlet connection can be rotated to vary the amount
of chemical pick-up. Turn clockwise to REDUCE, anti-clockwise to INCREASE.
To discontinue the chemical feed simply remove the tube from the chemical
container or push the sleeve on the vario nozzle back to the (PRESSURE) position.
MAINTENANCE
Some aspects of maintenance have already been referred to in this booklet and
others can be found in the accompanying engine manufacturers handbook.
Here we mention some which are particularly important.
1.
After each use ensure that the entire system is flushed through with clean
water particularly if chemicals have been used.
Ideally, all the equipment should be stored in a frost free location, but if this is
not possible, then anti-freeze should be mixed with the flushing water, or
otherwise the machine must be completely drained. To assist in the removal
of water the engine may be run for a maximum of 15 seconds after the water
supply has been turned off. Do not run for any longer period otherwise
damaged may occur to the pump.
2.
Regularly check the oil levels in both the pressure washer pump and the
petrol engine. We recommend that the oil in the high pressure pump be
changed affer approximately each 100 hours of operation. Do not mix oils of
