1.1. ELECTRICAL SAFETY
WARNING! It is the responsibility of the owner and the operator to read, understand and comply with the following:
You must check all electrical products, before use, to ensure that they are safe. You must inspect power cables, plugs, sockets and any other
connectors for wear or damage. You must ensure that the risk of electric shock is minimised by the installation of appropriate safety devices. A
Residual Current Circuit Breaker (RCCB) should be incorporated in the main distribution board. We also recommend that a Residual Current
Device (RCD) is used. It is particularly important to use an RCD with portable products that are plugged into a supply which is not protected
by an RCCB. If in any doubt consult a qualified electrician. You may obtain a Residual Current Device by contacting your Sealey dealer.
You must also read and understand the following instructions concerning electrical safety.
1.1.1. The Electricity at Work Act 1989 requires all portable electrical appliances, if used on business premises, to be tested by a qualified
electrician, using a Portable Appliance Tester (PAT), at least once a year.
1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of those appliances
and the safety of the appliance operators. If in any doubt about electrical safety, contact a qualified electrician.
1.1.3. Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply. See 1.1.1. and 1.1.2.
and use a Portable Appliance Tester.
1.1.4. Ensure that cables are always protected against short circuit and overload.
1.1.5. Regularly inspect power supply cables and plugs for wear or damage and check all
connections to ensure that none is loose.
1.1.6. Important: Ensure that the voltage marked on the appliance matches the power supply
to be used and that the plug is fitted with the correct fuse - see fuse rating at right.
1.1.7. DO NOT pull or carry the appliance by the power cable.
1.1.8. DO NOT pull the plug from the socket by the cable.
1.1.9. DO NOT use worn or damaged cables, plugs or connectors. Immediately have any faulty
item repaired or replaced by a qualified electrician. When an ASTA/BS approved UK
3 pin plug is damaged, cut the cable just above the plug and dispose of the plug safely.
Fit a new plug according to the following instructions (UK only).
a) Connect the GREEN/YELLOW earth wire to the earth terminal ‘E’.
b) Connect the BROWN live wire to the live terminal ‘L’.
c) Connect the BLUE neutral wire to the neutral terminal ‘N’.
d) After wiring, check that there are no bare wires, that all wires have been correctly
connected, that the cable outer insulation extends beyond the cable restraint and that the restraint is tight.
Double insulated products, which are always marked with this symbol , are fitted with live (brown) and neutral (blue) wires only.
To rewire, connect the wires as indicated above - DO NOT connect either wire to the earth terminal.
1.1.10. Products which require more than 13 amps are supplied without a plug. In this case you must contact a qualified electrician to ensure
that a 30 amp supply is available. We recommend that you discuss the installation of an industrial round pin plug and socket with your
electrician.
1.1.11. If an extension reel is used it should be fully unwound before connection. A reel with an RCD fitted is preferred since any appliance
plugged into it will be protected. The cable core section is important and should be at least 1.5mm², but to be absolutely sure that the
capacity of the reel is suitable for this product and for others which may be used in the other output sockets, we recommend the use
of 2.5mm² section cable.

Important! The washer motor will stop as soon as the gun trigger is released and will restart when the trigger is squeezed.
Always allow at least 5 seconds between releasing the trigger and restarting.
5.1. Primary checks. Check that the inlet filter is clean; pump delivery and pressure will be reduced if blocked. Never use the machine
without a filter ( which is fitted inside the hose connector, see fig.2-1). Ensure that the water supply, high pressure hose and gun are
correctly connected, and that air can freely circulate around the washer.
5.2. Operation of safety catch. To prevent inadvertent operation of the unit the safety catch should always be engaged when the gun is
not in use. Swing the catch into position over the end of the trigger as shown in fig.8-3. To release the catch press it above the trigger
as indicated in fig.8-1.
5.3. Operating the machine. 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.
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. Switch the machine on by pressing the button marked ‘I’ as shown in fig.7 above.
Release the safety catch (see fig.8-1). 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).

 WARNING! Ensure you read, understand and apply Section 1 safety instructions.
 WARNING! Dry running can seriously damage the unit.
 WARNING! DO NOT leave washer switched on for more than 15 minutes without operating trigger.
Original Language Version PC3455 Issue No.2 19/08/10

5.4. Adjusting spray pattern and pressure. (Variable Nozzle, see contents, item 10) The spray pattern can be continuously varied from
a fine jet to a fan pattern by rotating the body of the nozzle as indicated in fig.9. Furthermore the pressure can be switched between
high and low by pushing or pulling the nozzle along the axis of the lance. Shifting the nozzle forwards selects low pressure as shown
in fig.10. Shifting the nozzle backwards selects high pressure as shown in fig.11.
5.5. Using detergent. (Variable Nozzle, see contents, item 10) Use only detergents approved for use in pressure washers. (See fig.12)
For soap application use the low pressure setting on the lance. (If the high pressure setting is selected detergent solution will not be
discharged.) Remove the plug from the detergent reservoir situated at the back of the machine and fill it with a suitable cleaning
solution. Select the low pressure setting on the nozzle. The chemical will be automatically mixed with the water and discharged
through the nozzle.
5.5.1. Dirt is dissolved by applying detergent to the dry surface.On vertical surfaces, work from the bottom upwards.
5.5.2. Leave the detergent to act for 1 - 2 minutes, but DO NOT allow the surface to dry out.
5.5.3. To wash down select the high pressure setting on the lance.
5.5.4. The rotary nozzle (see contents, Item 11) gives a high torque cleaning effect on larger areas (ideal for vehicle washing and
removing grime from patio surfaces). Apply the high pressure jet keeping the end of the nozzle approximately 25cm (10”) from
the surface.
5.6. When washing is completed.
5.6.1. Switch the power supply off by pressing the button marked ‘O’ as indicated in fig.7.
5.6.2. Turn off the water supply tap.
5.6.3. Switch the motor back on to discharge residual pressure by pressing the trigger until no more water comes out of the nozzle.
5.6.4. Switch the motor off, engage the trigger safety catch and unplug the machine from the electrical mains power supply.
5.6.5 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.
d) If storing the washer for a long period during winter, operate the washer with a non-corrosive, non-toxic anti-freeze before storage.
Store detergents according to instructions on the container label.
 WARNING! Ensure the pressure washer is switched off and unplugged from the mains electrical power supply and turned off at the
mains water tap before performing any maintenance tasks.
7.2. Check, clean or renew the inlet filter ( which is fitted inside the hose connector, see fig.2-1) after every 50 hours of use.
