Maintenance Contract; Frost Protection - Kärcher HDI 60/10 Bedienungsanleitung

Maintenance contract

You can enter into a maintenance contract
with the concerned Kaercher Sales Office
for the machine.
Cleaning the sieve
 Shut off water supply.
 Screw on the dirt catcher and remove
the sieve.
 Clean sieve.
 Assemble it back in the reverse se-
quence.

Frost protection

The machine should be stored in frost-free
rooms. In case there is frosting risk, for e.g.
if the machine is installed in open areas,
then the machine must first be emptied and
flushed using an anti-freezing agent.
Drain water
 Screw off water supply hose and high
pressure hose.
 Operate device for max. 1 minute until
the pump and conduits are empty.
Flush device with anti-freeze agent
Note: Observe handling instructions of the
anti-freeze agent manufacturer.
 Fill in normal anti-frost agents in the
swimmer tank right until the top.
 Place the collection trough under the
high pressure exit.
 Switch on the appliance and let it run
until the safety mechanism against lack
of water in swimmer tank gets activated
and the machine is switched off.
A certain corrosion protection is achieved
with this as well.
Descaling
Calcium deposits in the water system of the
high pressure cleaning system lead to in-
creased pipeline resistance and possibly to
the failure of calcified components.
DANGER
Risk of explosion due to combustible gas-
es! Smoking strictly prohibited during de-
calcification. Ensure proper ventilation.
DANGER
Risk of chemical burns on account of acid!
Wear protective glasses and protective
gloves.
According to statutory requirements, only
tested and approved boiler decrusting
agents may be used.
– RM 100 (Order No. 6.287-008) dis-
solves chalk and simple compounds of
chalk and detergents residues.
– RM 101 (Order No. 6.287-013) dis-
solves the deposits that cannot be dis-
solved using RM 100.
These agents match with the materials
used in the system. We recommend rinsing
the system with an alkaline solution to neu-
tralise the acid residue after the decalcifica-
tion (pH value 7-8).
The application and accident prevention
regulations must be adhered to (concentra-
tion must comply with the values on the
bulk label).
Procedure:
 Remove the high pressure hose from
the network supply and hang it in the
storage reservoir. Fill 7 percent decalci-
fication solution into the storage reser-
voir. Drive briefly in circulation mode, let
it sit, rinse.
