SAFETY PRECAUTIONS
No welding is permitted on AL-KO Axles.
It is important that the wheel and hub/brake drum are
compatible. This means that the PCD, wheelbolts and inset
must all be compatible with both the hub/brake drum and
the wheel rim. Particular attention must be paid to the
recommended torque gures for the wheelbolts (page 16).
The axle type details shown on axle type plates must not be
obscured or made illegible by application of any additional
surface nish.
OPERATING INSTRUCTIONS
Service Brake
When the towing vehicle is braking or travelling down hill,
the overrun device shaft is pushed in (dependent on the
magnitude of the thrust on the shaft) and presses on the
overrun lever. This acts on the Bowden cables and expander
mechanism, which in turn expands the brake shoes applying
the wheel brakes.
Reversing
When the towing vehicle is reversing, the overrun device shaft
is pushing in, applying the brakes via the overrun lever, brake
rod system, Bowden cables and the expander mechanism. The
backwards rotation of the brake drum causes the secondary brake
shoe to collapse cancelling out the braking effect, allowing the
trailer to move backwards. At the same time the transmission lever
swings back and compensates for the entire travel.
Hand Brake
With the Euro Hand Brake, pull the lever until upright. The caravan
is then braked.
IMPORTANT NOTE
Please note that with the handbrake fully applied, the caravan/
trailer is able to move backwards by 25 cm until the spring
cylinder/gas spring takes effect.
