SYMPTOMS
REASON
REMEDY
Motor will not start.
1. Loose or diconnected plug.
2. Tripped pressur
e washer thermal switch.
1. Reconnect plug.
2. Allow to cool and restart unit.
Circuit breaker trips or fuse blown.
1. Circuit Overload.
2. Extension cord too long or wire size too
small.
3. Nozzle partially blocked, causing
excessive pressure.
1. Check that the circuit is rated 13amps or
greater. Disconnect all loads on the circuit.
2. Use proper extension cord as
recommended in section 1.
3. Clean nozzle as described in maintenance
section.
Water or oil leaking from bottom of pump.
1. A small amount of leakage is normal.
1. If excessive leaking occurs contact
authorised service agent.
Trigger will not move.
1. Gun safety lock engaged.
1. Release safety lock.
Unit will not stop when trigger is released.
1. Trigger system not operating properly.
1. Contact authorised service agent.
Motor running but pump not building
maximum pressure or has irregular pressure.
1. Water supply not turned on.
2. Unit has been stored in freezing
temperatures.
3. Water inlet screen clogged.
4. Kink in supply hose.
5. Nozzle worn out.
6. Air in pump.
7. Suction or discharge valves clogged or
worn out.
1. Turn on water supply.
2. Thaw out unit completely including hose,
gun and attachments.
3. Clean screen as described in maintenance
section.
4. Straighten hose.
5. Replace nozzle.
6. Let pressure washer run with gun open
and lance removed until a steady stream
of water is released.
7.Contact authorised service agent.
5.4
Operating the machine.
5.4.1 Hold the spray gun firmly to counteract the recoil caused by the high pressure of the water. Before switching on ensure that the lance
is not directed at people, objects or animals prior to being directed at the object to be cleaned.
5.4.2 It is recommended that the trigger is depressed before switching on the unit before every use. This reduces the back pressure and
amperage draw which prevents fuses blowing.
5.4.3 Switch the machine on by turning the switch to the 'On' position as shown in fig.1. Release the handle safety catch (fig.6). Point the
lance at the object to be cleaned and fully depress the trigger. When the trigger is released the motor will automatically switch off.
5.5
Adjusting spray pattern.
The fan nozzle attachment can be continuously varied from a fine pencil jet to a fan pattern by rotating the
body of the nozzle as indicated in fig.5.
Caution!
The pencil point setting is very aggressive. It is recommended that for most cleaning applications, a twenty degree spray angle is
used to avoid damage to the surface being sprayed.
Note:
The pressure of the spray on the surface you are cleaning increases as you move the nozzle closer to the surface.
5.5.1 For the high pressure Turbo spray fit the turbo nozzle (fig.1.8). This nozzle is intended for maximum cleaning affect.
5.6
Using detergent.
Use only detergents approved for use in pressure washers.
5.6.1 Remove the nozzle that is attached to the gun and attach the soap dispenser (fig.1.12).
5.6.2 Remove the bottle and check that the tube is not blocked.
5.6.3 Fill with detergent suitable for use with a pressure washer and screw on the bottle. The detergent will automatically be mixed with the
water and discharged through the nozzle.
5.6.4 Dirt is dissolved by applying detergent to the dry surface.
On vertical surfaces, work from the bottom upwards.
5.6.5 Leave the detergent to act for 1-2 minutes, but
DO NOT
allow the surface to dry out.
5.6.6 To wash down select the Variable spray jet nozzle (fig.1.9) set on the wide fan setting (fig.5A).
5.6.7 When you have finished the soap application, remove the bottle and flush clean water through the tube until it is thoroughly cleaned.
Note:
Failure to clean properly will cause the injection system to become clogged and inoperable.
5.7
When washing is completed.
5.7.1 Switch the power supply off by turning switch to 'Off' position.
5.7.2 Turn off the water supply tap.
5.7.3 Discharge residual pressure by pressing the trigger until no more water comes out of the nozzle.
WARNING!
Failure to discharge pressure could result in personal injury.
5.7.4 Disconnect the inlet and high pressure outlet hoses.
5.7.5 Wipe the machine clean and dry and store in a clean, safe, dry, childproof location.
Note:
a)
DO NOT
leave motor switched on for more than 15 minutes without operating trigger.
b) If the water pressure drops (i.e. someone else using the same water supply), the washer will not operate correctly.
Immediately switch off the motor and wait until the pressure is restored.
c) Should the motor stop and fail to restart, the built in thermal cut-out may have tripped. Check to ensure that the washer is
connected correctly to electrical and water supplies (also see Section 6 Troubleshooting). Wait 5 minutes for the cut-out
to reset and re-start the motor. If the motor continues to cut out contact your authorised service agent.
