SYSTEM 920/400
GB
7
IMPORTANT!
The system is designed for use only with statio-
nary vehicles. When the hose nozzle has been
connected to the vehicle exhaust pipe, the vehicle
must not be moved. A = 1,5 - 2,5 m, depending on
hose length and the mounting height of the rail
(see picture on top of page 2).
Ratchet mechanism
See picture bottom left of page 2. System 920/400 with
balancer is delivered with a ratchet mechanism which
retains the hose in the required outdrawn position.
The ratchet will disengage if the hose is drawn out a
little further. The hose then returns automatically but
should be held by hand
until it has moved to its rest
position.
Damper function
See picture bottom left of page 2. System 920/400 can
be fitted with a mechanical damper which automati-
cally opens when the hose is drawn out. The damper
closes when the hose has returned to its rest position.
A
= closed position,
B
= open position.
Adjusting the lifting power
of the balancer
See picture bottom right of page 2. The balancer has
a factory set lifting power. It is possible to adjust the
lifting power according to the following description.

1.
Loosen the stop ball (
C
)
2.
Unscrew the safety screw (
A
).
3.
Use a locking handle (
B
) and turn anti-clockwise
one revolution at a time. Each revolution is marked
with a "click" position. Turn until the hose has moved
to required resting position.
4.
Push the stop ball (
C
) up to the stop clamp adjusting
screw (
D
). Fasten the stop ball in this position.
5.
Turn the locking handle one revolution more.
6.

clamp and that the damper is closed. If not, screw
the adjusting screw (
D
) downwards a little.
7.
Fasten the safety screw (

If necessary, adjust the stop ball position on
the cord.
Checking of procedure
1.
Make sure the safety screw (

2.
Pull the hose to its maximum extent and check
that the balancer winds the hose to its normal position
at an even and steady pace. Hold the hose by hand
while it returns.
