ELECTRICAL CONNECTIONS
Before switching the product on, make sure that the voltage of your electricity
supply is the same as that indicated on the rating plate. This product is
designed to operate on 230VAC 50Hz. Connecting it to any other power
source may cause damage.
This product may be fitted with a non-rewireable plug. If it is necessary to change the
fuse in the plug, the fuse cover must be refitted. If the fuse cover becomes lost or
damaged, the plug must not be used until a suitable replacement is obtained.
If the plug has to be changed because it is not suitable for your socket, or due to
damage, it should be cut off and a replacement fitted, following the wiring instructions
shown below. The old plug must be disposed of safely, as insertion into a mains socket
could cause an electrical hazard.
• The wire which is coloured Blue must be connected to the terminal
which is marked Nor coloured Black.
• The wire which is coloured Brown must be connected to the terminal
which is marked Lor coloured Red.
• The wire which is coloured Yellow and Green must be connected to
the terminal which is marked E ( ) or coloured Green.

mains supply.
3. Release the trigger lock.
• The pressure washer is now
ready for use.
4. Press the start switch (‘I’).

ADJUSTING THE SPRAY
The nozzle is adjustable to allow you to adjust the spray from a narrow jet of
water to a wide spray.
To adjust the nozzle, proceed as
follows:
1. Hold the shaft of the lance in one
hand.
2. Twist the nozzle with the other
hand.
3. To vary the spray between narrow
and wide, turn the nozzle
anticlockwise through 180o.
ADJUSTING THE PRESSURE
There are three ways to adjust the
pressure of the water:
1. Slide the nozzle forwards to lower
the pressure.
2. Back away from the surface
being cleaned. The further away
you are the less the pressure will
be on the surface being cleaned.
3. Adjust the spray to a wider angle.
APPLYING CHEMICALS AND CLEANING SOLVENTS
1. Ensure the trigger is locked.
2. Remove the cap from the detergent container.
3. Fill the container with a suitable bio-degradable detergent.
4. Replace the cap.
5. Squeeze the trigger.
6. Pull the adjusting sleeve forward to set the required spray pressure.

pulsate. Clean the nozzle immediately as follows:
1. Turn off the power washer and turn off the water supply.
2. Pull the trigger to relieve any water pressure.
3. Disconnect the lance from the spray gun.
4. Remove any obstructions by directing water supply into the end of the
lance for 30 seconds to back flush loose particles.
5. Reconnect the lance to gun and turn on water supply.
REMOVING THE SPRAY GUN FROM THE HOSE
The gun can be disconnected from the hose for cleaning or to unblock the
spray gun/hose by disconnecting the connection using a 17 mm spanner.
Pull the hose away from the spray gun.
CLEANING THE WATER INLET FILTER
This filter should be checked periodically and cleaned if necessary.
1. Remove filter from the water inlet
of the pump as shown.
