Using as short a length of hose as practicable, connect one end to the water
inlet, using the hose adaptor supplied, then fill or prime the hose with water before
placing the other end into the water supply.
Take special care to see that no foreign matter is likely to be drawn up into the
hose. If necessary, use some form of filter (not supplied) to prevent this from
happening.
HIGH PRESSURE CONNECTION
The high pressure hose (Item 1) is supplied already connect to the trigger assembly
(Item 6). The other end of the hose is fitted with an adptor which should be carefully
connected to the high pressure outlet (Item 9). Tightening the connector by hand
is normally sufficient to ensure a proper seal.
The front end of the operating lance is referred to as the vario nozzle (Item 7) and
this connects to the rear assembly containing the trigger by means of a simple
bayonnet fitting.
Once all the water connections are complete and if you are using a positive
feed system, turn on the water supply and operate the trigger to ensure a flow
through can be obtained.
N.B.A safety catch is fitted to the handle of the trigger assembly. When this is
engaged it prevents the trigger from being operated.
This facility should be used if the operator has to relinquish control of the lance for
any reason, whilst the engine is running.
OPERATION
Before starting the engine and with the machine on a level surface, check the oil
level sight-glass on the power washer pump to ensure that it is around the mid-
way mark. If necessary top up the oil level using SAE2O/30 oil, but do not overfill.
Now refer to the engine manufacturers handbook and complete all the preliminary
checks including oil and fuel levels before starting the engine.
If using feed water supply, this should be turned on before starting the engine, If
using suction feed, ensure that everything is in place, so that water will be drawn
up quickly into the pump.
To prevent possible damage to the pump, turn the engine off if the water supply
fails for any reason.
Once the machine is up and running, there are two adjustments which can be
made to the vario nozzle (Item 7) to vary the pattern and intensity of the spray.
The front portion can be turned to adjust between a direct jet and a fan spray.
Also by gripping the sleeve portion of the vario nozzle and following the directions
of the white arrows, the assembly may be pushed forward (INJECTION) for a low
pressure washing spray or pulled back (PRESSURE) for maximum cleaning effect.
The pressure gauge fttted to the pump provides a general indication of the
operating pressure which should be 1500 psi (100 bar). This is the maximum
