Demon International HURRICANE D1 SALT WATER, Operation Manual

Page: 4 / 21

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, tighten where necessary.
Leaving the pressure washer on by-pass for prolonged periods without operating 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.
WHEN USING CLEANING AGENTS
a.
Set machine up for water only.
b.
Connect detergent hose to machine and place filter 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 automatically injected into the water.
c.
On completion of work, flush through hose and gun with clean water to remove any residual
detergent.
SERVICING
The Storm range require little 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 dipstick, 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 ineffective contact the service depart-
ment to ascertain the correct remedial repair work.
If using sea water flush after use with fresh water and spray any 3 way valves with silicone spray to
lubricate valve.
