6. MAINTENANCE (WASHER)
6.2
Check and clean the water inlet filter every 50 operating
hours. The filter is moulded into a rubber washer. Unscrew
the brass connector from the black fitting on the water inlet on
the pump. Push the black fitting backwards which will eject
the filter/washer and then clean the filter washer. If the filter is
damaged in any way it should be replaced.
6.3
Check and clean the detergent filter at the end of the
detergent input tube on a regular basis.
6.4
WINTER STORAGE:
Fill the pump with an antifreeze
mixture before storing in a frost free, safe, dry area for the
winter. Introduce the antifreeze by the following method.
6.4.1
Shut off the water supply and disconnect the supply hose.
Relieve pressure within the pump by squeezing the gun
trigger. Remove the high pressure hose and let all water drain
from it. Hold gun/lance with nozzle downwards and pull
trigger until all water has drained out.
6.4.2
Connect a short length of garden hose to the water inlet and
using a funnel pour an antifreeze mixture into it.
6.4.3
Pull the recoil starter several times to circulate the antifreeze
through the pump. Continue to add antifreeze and pull the
recoil until antifreeze is expelled from the pump.
5.1.
MANUAL 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
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.
5.1.4
Rotate the engine switch clockwise to the ON position. See fig.8.
5.1.5
Fig.7 shows the fuel tap in the OFF position. Push the
fuel tap up to the right to the open position.
5.1.6
If the engine is cold move the choke lever to the left to close
the choke.
5.1.7
Move the throttle lever slightly to the left, fig.7 shows the
throttle in the full throttle position.
5.1.8
Turn the engine switch to the ON position.
5.1.9
Take hold of the recoil starter handle (see fig.1) and pull it
slowly until you feel resistance, then let it return slowly.
5.1.10 Now pull the starting handle hard and fast all the way out. Use
two hands if necessary.
5.1.11 If the engine doesn’t start repeat the process from 5.1.9.
5.1.12 Once started adjust throttle valve to the required setting and
return the choke to the open position when the engine is warm.
5.2.
CLEANING
5.2.1. Only apply detergent using the BLACK low pressure nozzle.
5.2.2. Depress the trigger to apply the detergent to the
dry surface
which is to be cleaned.
Vertical surfaces should be cleaned from the bottom upwards.
5.2.3
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.
5.2.4. Leave the detergent to act for 1-2 minutes, but
DO NOT
allow the surface to dry.
fig.7
fig.8
fig.9
5.2.5. 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.
5.3. SHUT DOWN PROCEDURE.
5.3.1
When cleaning has finished and the unit is no longer
required allow the engine to run unloaded for 2 minutes
before shutting down.
5.3.2
Stop the engine by pushing the throttle lever fully to the right.
(See fig.7) and turn the engine switch to the OFF position.
5.3.3
Turn off the fuel tap. (See fig.7)
5.3.4
Turn off the mains water supply.
5.3.5
Discharge residual pressure from the washer by pressing the
trigger until no more water comes out of the nozzle.
5.3.6
Engage the gun trigger safety catch.
5.3.7
In an emergency turn the engine switch to the OFF position.
CAUTION!
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 the washer
will not operate correctly. Switch the engine off
immediately and wait until the pressure is restored.
Maintenance should only be performed with the engine turned
off and the unit disconnected from the mains water supply.
6.1
CLEANING THE NOZZLES:
Pull back the brass sleeve on
the end of the lance and pull out the nozzle. Clean the nozzle
with wire provided (fig 9). If this does not improve the flow
from the nozzle it should be replaced.
