Read the operating insstructions and ac
accordingly. Keep the operating instruc-
tions for general use.
Obey the safety information and the
warnings on the device.

Safety Precautions
• No welding is permitted on AL-KO axles.
• It is most important that the wheel and hub/brake
drum are dimensionally compatible. This means
that the P.C.D., wheel bolts 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 figures for the wheel bolts.
• The axle type details shown on axle type shield
must not be obscured or made illegible by the
application of any additional surface finish.
• Remember! After driving for at least 20 km and at
the most 100 km it is vitally important that the
wheel nuts are tightened!
Operating Instructions
Function:
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 pushed in, applying the brakes via
the overrun lever, brake rod system, bowden cables
and the expander mechanism. The backwards rota-
tion 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 com-
pensates for the entire travel.
Parking Brake:
With the gas strut version pull the hand-brake lever
over top dead centre.
With the spring cylinder version pull the hand-brake
lever right up to the last tooth. The trailer is then
braked.
Important Note
Please note that with the handbrake fully applied
the trailer is able to move backwards by 25cms until
the spring cylinder/gas spring takes effect.
Maintenance and Cleaning:
Maintenance of Euro-Plus
Euro-Compact
Euro-Delta semi-trailing arm axle
The AL-KO Euro-Plus / Euro-Compact and the
Euro-Delta semi-trailing arm axles come fitted with
maintenance free wheel bearings (greased and sea-
led for life) and no adjustment is necessary.
N.B. The hub bearing is not protected against water
ingress.
Check wheel brake linings for wear every 10 000
kilometres or every 12 months via the inspection
hole (Fig. 2/1). Adjust if necessary. Where conti-
nuous travel in hilly regions or high mileage is expe-
rienced earlier inspection and adjustment may be
necessary.
Note that travel of more than 60% of total overrun
device shaft movement is indicative that brake
adjustment is required.
N.B. All necessary service work should only be car-
ried out by trained personnel in specialist
workshops.
“Standard axle” maintenance - taper roller bea-
ring
After 1500 km or 6 months;
- have the axial play of the hub bearing checked
and adjusted, if necessary.
After 10000 km or 12 months
- check quantity and quality of grease, renew if
necessary.
- With boat trailers which are driven into water or
sea water the hub bearing should be regreased
shortly after contact with the water (with the
exception of waterproof hubs).
- Check the wear of the wheel brake linings every
10 000 kilometres or every 12 months through
inspection hole and have adjusted, if necessary.
Where continuous travel in hilly regions or high
