A locking screw is required for 1 nozzle op-
eration (see accessories).
* Standard
Note: The use of a dirt filter in the high-
pressure line is recommended, but the
sieve should be cleaned regularly.
DANGER
Risk of fatal injuries on account of electric
voltage! Required electrical work must only
be performed by an electrical specialist.
– The socket must be secured through a
residual current device (RCD) with a
triggering current of 30 mA.
– This socket must be located close to the
work station so that the plug can be
pulled immediately in case of an emer-
gency.
1 Screwed sealing plug
2 Bevel wheel
3 Axle stub
4 Drum screws or hole cone
Loosen the locking screw.
Remove the disc and the circular blank.
Pull off the bevel wheel.
Unscrew axel stub by means of a round
tool (2.8 mm diameter).
Insert or replace drum screws or hole
cone.
Coat the axle stub with sealant (Loctite
no. 500, order no. 6.869-002) and
screw it in.
Attach bevel wheel.
Mount the disc and the circular blank.
Lubricate locking screw with sealant
and screw it in.
DANGER
Risk of injury on account of the escaping
water jet that could be hot!
– Only use the interior cleaner in closed
containers.
– Only insert the interior cleaner into a
container or switch it into another con-
tainer while the separate high pressure
pump and internal drive are turned off.
Note: Try to arrange the interior cleaner
centrally.
Screw the interior cleaner onto the ob-
ject to be cleaned using the screw con-
nection on the support pipe; or, with the
hole cone model, insert and adjust the
immersion depth.
Connect the high pressure pump to the
interior cleaner via a high pressure
hose.
Plug in the mains plug.
Open the cleaning liquid supply.
Switch on the separate high pressure
pump.
Note: With almost all cleaning tasks, 2 noz-
zles will achieve a good cleaning result.
With very large and extremely dirty contain-
ers, 1 nozzle is used; the other one is
locked with a screw.
Advantage:
– Better cleaning result by larger spray
width and impact force of the cleaning
jet.
Disadvantage:
– The bearings and seals are stressed
more and will wear faster.
– Extension of the cleaning time.
