Preparaon
Water Supply:
a. Ensure there is an adequate water supply either from the mains or a reservoir.
NOTE: ONLY CLEAN FILTERED WATER SHOULD BE USED.
Hoses:
a. Aach the high pressure hose to the pump connecon.
b. Aach the spray gun to opposite end of the high pressure hose.
c. Ensure that the regulator nozzle on the end of the spray lance is CLOSED.
OPERATION
(Check that electric motor is switched ‘OFF’)
a. Plug into a suitable electrical source. (Not an extension lead)
b. Turn on water supply.
c. Ensure that the trigger is ‘OPEN’ to vent air from the pump.
d.Switch ‘ON’ electric motor.
e. Open regulator nozzle slightly and direct lance on surface to be cleaned. Press
operang trigger.
f. Adjust pressure regulator as required to obtain working pressure.
g. NOTE: The high pressure water will cause the gun to ‘kick’. Make sure you have a
rm grip of the gun and lance.
h. On compleon of the operaon switch ‘OFF’ electric motor and unplug from power
supply.
i. Turn ‘OFF’ water supply.
j. Release residual pressure in gun and lance by operang trigger.

OPERATING HINTS
a. During very cold weather it is most important to protect the machine against freezing. DO
NOT operate machine should it become frozen. Move it to a warm area and allow to thaw
naturally.
b. Check all hoses and couplings for leaks, ghten where necessary.
WHEN USING CLEANING AGENTS
a. Set machine up for water only.
b. Connect detergent hose to machine and place lter end into detergent reservoir. Unscrew the
adjustable nozzle on the end of the lance to reduce the pressure to 500psi. The chemical will
now be automacally injected into the water.
c. On compleon of work, ush through hose and gun with clean water to remove any residual
detergent.
SERVICING
The Storm range require lile maintenance apart from checking the oil level at least every week and
changing the oil should it turn white or it is six mouths old. If the oil turns white it is due only to water
entering the pump via the dipsck, which has a breather hole drilled through. The design of the pump
does not allow water from the pump to gain access to the gearbox drive.
Should the performance be reduced to a level where the jet is ineecve contact the service depart-
ment to ascertain the correct remedial repair work.
If using sea water ush aer use with fresh water and spray any 3 way valves with silicone spray to
lubricate valve.
WARNING
Leaving the pressure washer on by-pass for prolonged periods without operang the lance will cause
the water in the pump to heat up. This heat build up may damage the seals and valves in the pump.

OPERATING INSTRUCTIONS
SAFETY
i. A Residual Current Device (R.C.D.) or Earth Leakage Trip must be used with this machine.
ii. Water at high pressure is dangerous and can cause serious injury. This machine is to be used
with great cauon.
a. NEVER point the high pressure spray jet at any person, animal, glass or any other material which
may shaer.
b. PREVENT any over-spray from injuring other people or damaging property.
c. DO NOT even try to use a pressure washer on machinery or electrical equipment that is
connected in any way to the mains supply. (all switches in the o posion, pull out all plugs and if
possible remove fuses). Cover or seal electric motors and ngs to prevent entry of water.
d. ALWAYS when using machine:-
- wear safety goggles and helmet or helmet with a visor.
- wear waterproof clothing and gloves.
- take parcular care with detergents and chemicals.
e. NEVER aempt to disconnect any hose with pressure in it or allow the hose to be aened or
f. DO NOT use a high pressure hose from a ladder. Use a plaorm tower or proper scaolding.
g. CHECK that your supply voltage agrees with that shown on the machine.
h. Demon do not recommend the use of an extension lead using an extension lead will result in
switch failure or motor damage. Demon strongly recommend the use of extension hoses as
opposed to extension leads. Warranty claims for damaged switches and motors used on extension
leads will not be allowed. Ask the service department if in doubt.
I. DO ALL you can to keep plugs and sockets in a dry place or covered to prevent entry of water.
j. Where a cable is found to be damaged, the power must be switched o and the plug removed
before aempng to remove the equipment.

FAULT CAUSE REMEDY
Machine stops suddenly
Or will not start. Blown fuse.
Check mains power supply, re-
place fuse. Wait unl unit cools
down before reseng switch.
Sudden pressure loss. Water supply failed. Check water supply.
Low pressure
HP nozzle worn or
unloader set
Incorrectly.
Replace HP nozzle. Set unloader
to correct seng.
Low pressure with noise and
vibraon.
Valves worn or
blocked. Piston seals
worn.
Pump sucking air.
Clean/replace as required.
Replace.
Check water supply pipe and un-
ions.
Pump will not by-pass. Non return valve
dirty or jammed. Clean or replace.
Water drips from pump box. Pump seals worn. Replace.
Oil drips from pump boom. Oil seal worn. Replace.
Oil is milky in colour.
