REPAIRS AT THE UNIT
10.5
REPLACING THE POWER CABLE
This may only be carried out by a skilled elec-
trician. No liability is assumed for incorrect
installation.
Switch the unit off.
Before all repair work: Unplug the power
plug from the outlet.
Do not dismantle the sealed pressure control
valve (1) so as to ensure that the pressure set-
ting is retained.
To remove the pump, move it to an upright
position. Open the oil lock screw (5) to re-
lease any excess pressure that has built up in
the hydraulic oil housing.
1. Completely unscrew the pressure control valve (1) (span-
ner width 17 mm).
2. Remove the front cover (2) by loosening the 5 screws
using an Allen key (SW 3).
3. Loosen the cable threaded joint (3).
4. Loosen the wires in the mains terminal (4).
5. Replace the unit connecting line.
(only an approved power cable with the designation H07-
RNF with a splash-proof plug may be used).
6. Connect the green/yellow wire to the contact with the PE
sign.
7. Remount the covers carefully (do not squeeze any cables!)
8. Replace the pressure control valve in the housing and
screw into position.

TYPICAL WEAR PARTS
Despite the use of high-quality materials the highly abrasive
effect of the paints means that wear can occur at the follow-
ing parts:
Inlet valve (spare part Order No.: 0341247)
For replacing refer to Section 10.2
(failure becomes noticeable through performance loss and/or
poor or no suction)
Outlet valve (spare part Order No.: 0341702)
For replacing refer to Section 10.3
(failure becomes noticeable through performance loss and/
or poor suction) The outlet valve is usually considerably more
durable than the inlet valve. Thorough cleaning may already
help here.
