5. SAFETY FEATURES
5.1.
THERMAL RELIEF VALVE
5.1.1.
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.
5.2.
TRIGGER LOCK
5.2.1.
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.
5.3.
LOW OIL SHUTDOWN
5.3.1.
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 8.2.

increase may damage sealing system.
6.1.
MANUAL STARTING PROCEDURE
6.1.1.
Check engine and pump oil level before each use.
6.1.2.
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.
6.1.3.
Release gun trigger safety catch and depress trigger to allow
any air left in the system to escape, hold until there is a steady
flow of water coming out and release the trigger.
6.1.4.
Rotate the engine switch clockwise to the ON position. See fig.8.
6.1.5.
Fig.7 shows the fuel tap in the OFF position. Push the fuel tap up
to the right to the open position.
6.1.6.
If the engine is cold move the choke lever to the left to close
the choke.
6.1.7.
Move the throttle lever slightly to the left, fig.7 shows the
throttle in the full throttle position.
6.1.8.
Turn the engine switch to the ON position.
Take hold of the recoil starter handle (see fig.1) and pull it
slowly until you feel resistance, then let it return slowly.
6.1.9.
Now pull the starting handle hard and fast all the way out. Use
two hands if necessary.
6.1.10.
If the engine doesn't start repeat the process from 6.1.9.
6.1.11.
Once started adjust throttle valve to the required setting and
return the choke to the open position when the engine is warm.
6.2.
CLEANING
6.2.1.
Only apply detergent using the BLACK low pressure nozzle.
6.2.2.
Depress the trigger to apply the detergent to the dry surface
which is to be cleaned.
6.2.3.
Vertical surfaces should be cleaned from the bottom upwards.
6.2.4.
When detergent application is complete remove the syphon tube
from the detergent container and place it in a container of clean
water. Run the washer at low pressure to purge the gun of
detergent.
6.2.5.
Leave the detergent to act for 1-2 minutes, but DO NOT allow
the surface to dry.
The detergent should be rinsed off using either the YELLOW
or WHITE high pressure nozzles depending on the spray angle
required. Do not use the RED nozzle as the aggressive
spray action may erode the surface being cleaned. Always
lock the gun trigger before changing nozzles.
5.2.6.
Hold the gun firmly with both hands and commence washing
with high pressure clean water. When rinsing work from the
top to the bottom to avoid streaks.
Note: Care should be taken when selecting the nozzle for the job in hand. The distance from the nozzle to the surface being cleaned
will depend on the condition of that surface. Always start further away and slowly move closer until the level of cleaning required is
achieved.
SHUT DOWN PROCEDURE
6.3.
6.3.1.
When cleaning has finished and the unit is no longer required allow the engine to run unloaded for 2 minutes before shutting down.
6.3.2.
Stop the engine by pushing the throttle lever fully to the right. (See fig.7) and turn the engine switch to the OFF position.
