4.1
THERMAL RELIEF VALVE.
4.1.1 A thermal relief valve is fitted to protect the machine from
overheating if the gun remains closed for an extended
period of time or if the nozzle becomes blocked. To prolong the
life of the washer every effort should be made to avoid
overheating. It is recommended that if the unit is not going to
be used for two minutes or more it should be switched off.
4.2
TRIGGER LOCK.
4.2.1 To prevent accidental starting of the pressure washer the
trigger can be locked as shown in fig.4 by hinging out the
lever built into the back of the trigger and pressing it until it
locks into position. To release the locking lever flex the trigger
handle forwards and flip the lever out and fold it back into the
trigger. The trigger should be locked whenever the washer is
not in use.
4.3
LOW OIL SHUTDOWN.
4.3.1 The engine on this washer is equipped with a low oil shutdown
feature which stops the engine if the oil drops below a
specified level. Should the engine cut out, first check that it is
standing on a level surface. If the oil level is still low top it up
as described in Section 7.2.

3. ASSEMBLY / PRE-OPERATION
Unpack contents and check to ensure all parts are in good
condition. If you experience any problems contact your
dealer immediately.
3.1
ASSEMBLY. (See fig.1.)
3.1.1 Screw together the two halves of the lance as shown in fig.2.
3.1.2 Select an appropriate nozzle from the nozzle stowage area. Pull
back the spring loaded sleeve at the end of the lance and insert the
nozzle. Let go of the sleeve and check that the nozzle is firmly
gripped in the fitting. The nozzle selection is colour coded and offers
the following options.
BLACK
Low pressure wide angle spray for use with detergent.
RED
High pressure, 0° degree spray,
Very Aggressive
. Use
with extreme caution to prevent damage to the surface
being cleaned or injury to persons or animals.
YELLOW High pressure, 15° Spray angle, normal cleaning,
provides a wide coverage and powerful water stream.
WHITE
High pressure, 40° Spray angle, normal cleaning and
rinsing, provides a less powerful stream of water and is
suitable for most general cleaning jobs.
3.1.3 To attach the high pressure hose to the water inlet on the gun,
push it into the inlet on the gun until it is fully seated and tighten
as shown in figs.4 & 5.
3.1.4 Attach the other end of the high pressure hose to the pump
outlet as shown in fig.6. Push the end of the hose into the
pump outlet until it is fully seated and then tighten to secure.
3.1.5 Connect either a mains water supply hose or the siphon hose
to the pump inlet as shown in fig.6. USE COLD WATER ONLY.
Note:
The water supply hose must be reinforced and have an internal
diameter of 13mm (1/2”). The minimum water supply rate must
be at least equal to the washer flow rate.
The siphon pipe may require priming if drawing water from a
level lower than the pump.
3.2
DETERGENT DELIVERY.
3.2.1 Attach the BLACK low pressure nozzle to the end of the lance.
Remove the cap from a bottle of detergent and place the bottle
in the detergent holder.
3.2.2 On the top of the pump outlet is a brass siphon injection fitting.
Push the detergent input pipe onto the fitting (fig.6) and place the
filter on the other end into the container of detergent ensuring
that it goes all the way to the bottom. When used with the low
pressure black nozzle detergent will be drawn from the
container by siphonic action and will mix automatically with the
water from the pump. Use Sealey General Purpose Detergent,
AK130 (25ltr)
or
AK131 (5ltr)
. Traffic Film Remover is also
available,
AK132 (25ltr)
or
AK133 (5ltr)
.
