Checklist - Gerni G3H Mode D'emploi

G3H
To obtain the optimum performance and the
longest possible life for your high pressure
cleaner it is important to maintain the machine.
We recommend that you follow the following
directions and refer to the check list on the
next page.
OIL LEVEL/PUMP
Add oil in level with the lower edge of the oil
filling hole (for oil type and quantity please see
the technical data).
Water filter
Clean the water filter (2.9) as needed.
Disconnect the water inlet hose and remove
the water filter.
FUEL FILTER
We recommend that you change the filter once
a year or as the need arises.
If water is found in the fuel filter (4.36) change
the filter. Empty the fuel tank (2.11) Clean the
tank.
To prevent lime scale deposits from blocking
pipes, hoses and nozzles water softener is
added to the water which is fed into the tank
(3.32).
DESCALING
Even though the high pressure cleaner is
equipped with a water softener device we
recommend that the machine be regularly
descaled. Descaling is required if you find a
pressure increase of 5 bar or more over operat-
ing pressure.
1. Place the detergent pipe (2.34) into the des-
caling acid.
2. Dismount the lance (2.27) from the pistol
(2.26).
3. Start the cleaner and let it run for 1/2 min.
4. Close the pistol (2.26) a few times so the
cleaner is also descaled in the by-pass sys-
ACTION WHAT/WHO

tem.
5. Stop the cleaner and let the descaling acid
work for 5 min.
6. Restart the cleaner.
If the pressure is not down to the operating
pressure the process is repeated. After descal-
ing the system must be with clean water to
remove acid residues. Close the pistol a couple
of times so that the by-pass system of the
cleaner is flushed clean. The cleaner is then
ready for use again.
NOTE! Descaling acid is corrosive; wear facial
protection, protective gloves, etc.
FROST PROTECTION
The best frost protection is to place your high
pressure cleaner in a frost free environment. If
this is not possible the high pressure cleaner
must be frost protected as follows:
1. Remove the cover and turn off the water sup-
ply.
2. Turn on the machine, activate the pistol and
let the machine empty the water tank.
3. Add 4 liters of antifreeze mix to the water
tank (2.7).
4. Start the machine by turning the switch
(2.28) to pos. "AUT", activate the pistol
and let the machine run with the pressure
regulation handle in the open position until
antifreeze comes out of the nozzles (2.1) and
(2.2). Release the pistol trigger a couple of
times to frost protect the by-pass and safety
valve.
The antifreeze can be collected and used
again.
CHECK LIST
WHEN/HOW OFTEN
Before operator uses high pressure cleaner
During daily use
During daily use
Daily - by means of detergent
Weekly/as needed
As needed
Every other month
Twice a year/ as needed
Yearly/as needed
For pressure increase over 5 bar
Every other month
CLEANING
Always keep your high pressure cleaner clean.
This increases the life and function of the indi-
vidual parts considerably.
REPLACEMENTS/DESTRUCTION
All replaced parts such as water filter, fine sand
filter, as well as contaminated oil and antifreeze
must be handed in to the local approved
authority/institution for deposit/destruction.
When the high pressure cleaner is no longer
to be used, the detergent as well as pump and
stator oil must be drained off and delivered in
accordance with the above instructions. The
high pressure cleaner must likewise be handed
in to the local, approved institution for destruc-
tion.
Any replaced parts from service visits may be
given to the service personnel who will deliver
them to the proper authority.
