SERVICEHANDBUCH - Knott Brake Company

1. INTRODUCTION
The instructions for use and maintenance given below,
with operating regulations, relate to KNOTT chassis
components. They form a part of our warranty conditions.
In addition, the relevant operating regulations of
the vehicle manufacturer must be complied with.
To ensure continuing reliability and road safety in traffic,
the maintenance tasks have to be performed at the
prescribed intervals.
Maintenance, repairs and replacement of wearing parts
for the chassis and the braking system may only be
performed by a qualified garage.
Only original KNOTT spares may be used in order to
a) ensure proper functioning and safety,
b) preserve all rights under the guarantee and warranty,
c) prevent the operating licence from becoming invalid
under national and international
regulations.
The braking system, particularly the over-run hitch
and the wheel brakes, plus the draw poles, have been
tested according to the relevant EC guidelines and may
only be used in the licensed combination.
KNOTT chassis consist of the ball coupler, the over-run
hitch, the transmission system, the wheel brakes in
conjunction with KNOTT rubber, torsion thrust spring
and torsion spring axles, plus the drawgear, the draw
poles and/or the side bars as the case may be.
2. BALL COUPLERS
All KNOTT ball couplers are equipped with a safety
check indicator. This consists of clearly embossed
symbols to which a red-green-red label with the same
symbols has been glued, and an indicator button. If the
label is damaged, it can be removed and the embossed
symbols used, or the label can be replaced, in which
case the lines dividing the zones on the label and the
embossing must be aligned.
2.1 Uncoupling
To open, pull the coupling handle upwards and then
turn it forwards.

The trailer must never be driven in this
position!
!Caution:
Never insert your fingers in the open ball
coupler. Even slight pressure on the
sphere can trigger the spring-load closing
mechanism and result in injury to the fingers.
2.2 Coupling
To couple the trailer, place the open ball coupler (X position)
on the ball of the towing vehicle so that it clicks
into place audibly.
When the ball coupler has clicked properly into place,
the indicator jumps to the green zone marked "+”.

After coupling, it is essential to use the indicator check
that the ball coupler has clicked into place on the ball
correctly.
If the indicator is in the green "+” zone, the ball coupler
is correctly closed and locked, and the ball on the
vehicle still has sufficient wearing reserves.

towing vehicle and the trailer unless this
