e) Fully unwind the power cord when in use, to prevent overheating.
f) Use only extension cables with the same number of conductors as those of the machine
cable (including the earth) and with a suitable plug/socket for the cable to be used.
g) Only use extension cords designated for outdoor use. Such cables are marked “Suitable
for outdoor use.” This extension cord must be stored indoors when not in use.
h) Do not use a damaged extension cord. Cables should not be located near sources of
heat, sharp edges or water. Always disconnect the plug from the socket before
removing the extension cord from the product.
START UP
Before starting up the machine, ensure that it’s positioned on flat ground or leaning against a
stable support and that the resisting surface is level or with a minimum slope.
It is ESSENTIAL that you ensure the suction filter / inlet filter is clean before use (see

d) Check that pump has correct oil content –check sight glass. Oil should be half way up
sight glass. Also check breath hole in oil cap is clear. To stop oil from spilling when
transporting machine the breath hole may be closed by a pin, adhesive tape or a sealed
cap. Remove pin, adhesive tape or replaced sealed cap with dip stick cap, so that
breath hole is clear.
e) Set the pressure to zero by turning the knob anti-clockwise.
f) Turn on water supply. Maximum inlet water temperature must not exceed 60° C.
g) Check that there are no water leaks and ensure that the hose has no kinks or twists.
h) Before starting, point the lance to a safe position and open the gun trigger to release
any built-up pressure in the system. CHECK water is flowing through the machine and
out the lance prior to starting.
i) Once all checks have been completed, plug the unit into the electrical mains supply.
With single phase machines an earth leakage device is recommended.
Never let electric cords lie in pools of water
Keep plugs and motor dry at all times
DO NOT use long extension cords
j) Turn machine switch to the “ON”position while holding the trigger on the shut off gun
open to relieve back pressure.
k) Releasing the trigger will shut off the water flow.
a) Adjust the machine to your required pressure and then begin water blasting.
l) After turning unit off ALWAYS release pressure in gun. DO NOT leave pressure built up
in the hose gun.
To eliminate any impurities or air bubbles from the water circuit we advise starting the cleaner
for the first time without the lance and letting the water run out for a few seconds. Impurities
could block the nozzle and cause malfunction.
ALWAYS TURN OFF POWER SUPPLY AT THE WALL SOCKET AFTER USE, OR IF
MACHINE FAILS TO OPERATE.
WARNINGS:
Never let the unit run for more than 1 to 2 minutes with the gun
closed. Water will recycle within the pump head and heat up, causing
damage to seals.
Never let pump run dry of water as this can cause catastrophic
damage to the pump.
When your water blaster is not in use, close the safety device on the
handle (FIG 1).

GENERAL CARE & MAINTENANCE
INSTRUCTIONS FOR STORAGE & PRECAUTIONS AGAINS FREEZING
This machine should be cleaned daily after use, and checked for any maintenance
requirements. After using the detergent system it should be flushed with clean water. Simply
stand the detergent intake in a clean bucket of water and run the machine with the pump
nozzle or valve open for one minute.
Release any pressure in the hoses by depressing the trigger on the gun. Drain surplus water
from hoses and check for damage before storage. If the hoses are damaged in anyway,
replace immediately. Make sure hoses are stored with no kinks in them.
Check oil levels in both pump and motor. Allow motor to cool down before storage.
Store your water blaster indoors and in a dry area. Never leave equipment outside unprotected
from the elements. In particular do not leave equipment in low or sub-zero temperatures. In
very cold conditions it may be necessary to protect equipment by flushing it with antifreeze.
When storing the cleaner for long periods we also recommend the use of antifreeze solution in
order to avoid corrosion and drying up of the pump seals.
To do so:
a) Mix up antifreeze mixture in a separate container, as per manufacturer’s instructions.
b) Couple the container to the intake of the machine and gravity feed to pump.
c) Run machine for one minute to ensure system is primed with antifreeze mixture.
d) On stopping the machine, release pressure in hose by pulling trigger.

Remember: If the machine is operated in an area where freezing occurs, always check that
water lines are not frozen and take precautions to ensure that water does not freeze with the
pump. Before starting check that the water flow is normal. If in doubt do not use the
machine.
If in doubt about low temperatures or any long length of storage
time, we suggest you turn the motor with the key provided before
starting up. This activity helps to release any possible blockages
like ice or a buildup of lime scale deposits. Taking these
precautions before starting will avoid damage being caused to
the unit.
Remember to always remove the key before switching the
machine on.
OIL CHANGE
a) Regularly check the oil level to ensure it sits at the half way point in the sight glass, top
up as required.
b) Oil must be changed after the first 20 hours of operation of the machine. Subsequent oil
changes must be carried out every 150 hours of machine operation. It must be changed
at least once a year.
c) Used oil must be collected in containers and disposed of in special centers according to
current standards. It must not be discarded into the environment.
CLEANING THE INLET FILTER
Before using the machine it is important to make sure the filter is clean. Wash the filter under a
clean water tap or blow it with air to remove any dirt and debris. A well cleaned filter will help to
improve your water blaster’s performance and prolong the life of your machine.
