Electrical Connection - Kärcher HD 9/20-4 S ST Classic Bedienungsanleitung

Upright machine
4. Place the device on a level, horizontal and solid sur-
face on the four feet.
Connection of the high-pressure side to a
permanently installed pipeline network
Note
The applicable national regulations for permanently in-
stalled high-pressure cleaning systems must be ob-
served.
During installation, the specifications of the VDMA
standard sheet 24416 "High-pressure cleaners; perma-
nently installed high-pressure cleaning systems; terms,
requirements, installation, testing" must be observed
(available from Beuth Verlag, Cologne, www.beuth.de).
ATTENTION
Risk of damage due to pressure loss!
If the pressure loss in the high-pressure pipeline net-
work is greater than in the 10 m standard high-pressure
hose, the high-pressure pump can be damaged by
overloading.
Fit a correspondingly larger high-pressure nozzle to
compensate for the greater pressure loss.
1. Lay the pipeline network to be permanently installed
with as few changes of direction as possible.
Note
Observe the minimum cross-section of the pipelines:
DN 15 (½").
2. Route the pipeline network using padded loose and
fixed clips to compensate for pressure and thermal
expansion.
ATTENTION
Risk of damage due to vibration!
If the device is connected to the high-pressure pipeline
network with a rigid pipe, vibrations may cause damage
to the device or the high-pressure pipeline network.
Only connect the device to the high-pressure pipeline
network using a high-pressure hose line.
3. Connect the device to the pipeline network with a
high-pressure hose line.
Note
Observe the minimum cross-section of the high-pres-
sure hose line:

Installing an oil dipstick with breather valve
ATTENTION
Risk of damage due to under- or overpressure!
If the plug is not replaced with the dipstick with breather
valve before the initial startup, the high-pressure pump
may be damaged.
Be sure to replace the plug with the dipstick with breath-
er valve.
1. Unscrew the plug and dispose of it.

Checking / correcting the high-pressure
ATTENTION
Risk of damage due to insufficient lubrication or un-
suitable lubricants!
Too little oil or the use of unsuitable lubricants can dam-
age the high-pressure pump.
Before the initial startup, ensure that the oil level in the
high-pressure pump is sufficient and only fill with suita-
ble lubricants.
ATTENTION
Risk of damage due to water in the oil!
If the oil is milky, there is water in the oil, which damages
the high-pressure pump.
Do not operate the device with milky oil.
Contact Kärcher Service.
1. Set up the device horizontally, see chapter Attach or
set up the device.
Check the high-pressure pump oil level at the oil
level indicator
2. Check the oil level on the oil level indicator, it must
be in the middle of the sight glass.
If necessary, slowly top up oil, for specifications see
chapter Technical data.
Check the high-pressure pump oil level with the dip-
stick with breather valve
3. Unscrew the dipstick with breather valve and wipe
with a clean, lint-free cloth.
4. Insert the dipstick with the breather valve into the
bore, do not screw it in.
Illustration C
5. Pull out the dipstick with the breather valve and read
the oil level, it must be between the MIN and MAX
marks.
If necessary, slowly top up oil, for specifications see
chapter Technical data.
6. Wash your hands thoroughly with soap and water
after each contact with oil.
Installing accessories
Note
The EASY!Lock system connects components quickly
and safely via a single turn of the quick-release thread.
1. Connect the spray lance to the high-pressure gun
and teh union nut and hand-tighten (EASY!Lock).
Illustration D
2. Plug the high-pressure nozzle onto the spray lance.
3. Fit the union nut and hand-tighten (EASY!Lock).
4. Connect the high-pressure hose to the high-pres-
sure gun and high-pressure connection of the de-
vice and tighten hand-tight (EASY!Lock).

Electrical connection

DANGER
Risk of injury from electric shock
Use a plug to connect the device to the mains grid. Per-
manent connection to the mains grid is prohibited. The
plug is used for mains isolation.
Only connect the device to an AC power source.
Use an extension cable with sufficient diameter (see
"Technical data").
Unwind the extension cable completely from the cable
drum.
1. Unwind the mains cable and place on the ground.
