4. SAFETY FEATURES
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 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.4B by hinging out the lever built
into the back of the trigger and pressing it until it snaps into an
indent in the handle. To release the locking lever flex the trigger
handle forwards and flip the lever out of the indent 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 the
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.
5. OPERATION
 WARNING! RISK OF FLUID INJECTION. This washer
operates at fluid pressures and velocities high enough to
penetrate human and animal flesh. If there is an occurrence
of fluid injection seek medical help immediately.
 WARNING! Ensure you read, understand and apply
Section 1 safety instructions.
 WARNING! Dry running can seriously damage the unit.
 WARNING! DO NOT leave motor running for more than
2 minutes without operating the trigger, as
temperature/pressure increase may damage sealing system.
5.1. STARTING PROCEDURE.
5.1.1. Check engine oil level before each use.
5.1.2. Check that the mains water feed hose is laid straight, and
then fully open the water tap. Check to ensure there are no
leaks from hoses or connections.
5.1.3. Place the detergent input tube into the detergent container
(fig.2) ensure that the filter goes to the bottom of the
container.
5.1.4. Release gun trigger safety catch and depress trigger to allow
any air left in the system to escape, hold for 10 seconds and
release.
5.1.5. Rotate the engine switch clockwise to the ON position. See fig.7.
5.1.6. Fig.8 shows the fuel tap in the OFF position. Push the fuel tap
lever to the right to the ON position.
5.1.7. If starting the engine from cold move the choke lever fully to
the left. Fig.8 shows the lever in the OFF position.
5.1.8. Fig.8 shows the throttle lever in the slow running position.
Move the throttle lever to the left by a small amount.
5.1.9. To start the engine give a steady pull on the starting handle
whilst keeping the trigger pressed until the engine starts and
water flows from the nozzle.
5.1.10. As the engine warms up move the choke lever right into the
‘run’ position.
5.1.11. Adjust the speed
of the engine
using the throttle
lever.
5.2.
NOZZLE SPRAY
ADJUSTING (FIG 6).
Adjust the nozzle
pressure and spray
pattern as described in
section 3.3.
 CAUTIONS!
a) Avoid sudden
bursts of water as
this will cause the
water pressure to
drop and put
extreme pressure
on the hoses and
connections.
b) If another person
is using water from
the same supply as
the washer, the
water pressure will
drop and correctly.
Switch the engine
off mmediately and
wait until the
pressure is
restored.
