SECTION 1 SAFETY & GENERAL INFORMATION
This manual is provided as a supplement to the equipment manufacturer’s manuals.
This symbol calls your attention to instructions concerning your personal safety. Be sure
to observe and follow these instructions. This symbol accompanies a signal word. The
word DANGER indicates an imminently hazardous situation which, if not avoided, will
result in death or serious injury. WARNING suggests a potentially hazardous situation
which, if not avoided, could result in death or serious injury. CAUTION refers to potentially
hazardous situations which, if not avoided, may result in minor or moderate injury to
persons or equipment. Read all safety instructions before operating this equipment and
observe all safety warnings!
1.1 Safety Measures
The overruns are specially design for the new AL-KO wheel generation according to the
toxic substance regulation and EC directive.
When parking a towing vehicle with the trailer hooked on, one must apply the handbrake
of the trailer. If the trailer is disconnected from the vehicle, additional safety is given when
using two wheel chocks.
DANGER! The braking system may not function if used
with different wheel brakes.

1-2 TRdoc053121 Safety & General Information
1.2 Fitting and Adjustment
DANGER! Do not remove the spring hook of the
breakaway cable (safety for transport) until the overrun
device is mounted and the brake rod attached to the
transmission lever. Non-observance will mean the
handbrake does not work.
DANGER! The breakaway cable enables the trailer to
brake, should it become detached from the towing vehicle.
Loop the breakaway cable through the neck of the towball
and fasten with safety hook on the cable. Do not attach the
safety hook directly onto the hook.
DANGER! The breakaway cable automatically operates
the handbrake lever in the event that the trailer should
become detached from the towing vehicle. The driver is
therefore required to ensure that the cable is correctly
attached before every journey.
DANGER! Chock the trailer wheels to prevent movement
before unhitching it from the towing vehicle. Failure to do so
may result in serious injury or death.
DANGER! Be sure that the hitch and safety chains are
secure before towing the sawmill. Check all lights and
signals for correct operation. Check to see tires are
properly inflated and surge brakes are working before
towing the sawmill.
WARNING! Always check trailer tires for proper inflation
before towing sawmill.
CAUTION! Always keep away from tailer axle to avoid
being caught between the axle and moving saw carriage.

SECTION 2 MAINTENANCE
Replacing Dampers in 161 S / 251 S Overruns
Please ensure that a genuine AL-KO damper is fittied, which will automatically return the
drawbar after the braking process.
See Figure 2-1. The main components of the overrun device are shown below.
FIG. 2-1

DISMANTLING
1. Slacken off and remove screw (1).
2. Remove bellows (8) from the ball coupling (9).
3. Slacken off and remove screws (3).
4. Remove the defective shock absorber from the rear.
MOUNTING
1. Push the new shock absorber into the draw tube from the rear. Damper lug must be
parallel to drawbarholes in drawshaft.
2. Push screw (3) through the damper lug and lock check operating of coupling.
3. Push damper (6) in from rear and secure using screw and plate.
4. Locate bellows (8) on the screw(3). Torque: 86 Nm

SECTION 3 Adjusting the Braking System
3.1 Adjusting the braking force of the left and right wheel
Friction linings of the left and right wheel drums must be adjusted in such a way that the
braking force of the left and right wheel (or left and right wheels in case of two-axle
trailers) is the same.
1. To adjust the braking force of the brake drum, the wheel to be adjusted should be lifted
using a jack so that it can be freely rotated.
2. When the wheel is already lifted, remove the green cap located on the inside of the wheel
to expose the adjustment hole.
See Photo 3-1

3. Set the wheel in rotation as when travelling forward and use e.g. a screwdriver to move
the teeth in the adjustment hole in the direction indicated by the arrow until the wheel is
blocked.
See Photo 3-2
4. Then loosen the shoes by moving approx. 10 teeth in the adjustment hole in the opposite
direction until the wheel rotates freely.
5. Secure the adjustment hole using the cap removed earlier.
6. Repeat the steps described above for the second wheel (or remaining wheels in case of a
two-axle trailer).
