Troubleshooting - AL-KO 580 460 Manual Del Usario

CAUTION: If the handbrake is not fully applied as
detailed above there is a danger that the trailer
could roll backwards!
CAUTION: The brake rod must not be under
tension/bowed when the handbrake is disengaged,
otherwise the brakeaway mechanism will not
function.
Hand-brake lever with spring cylinder (Fig. 4):
Apply handbrake fully ensuring that handbrake is in
the vertical position.This will ensure that the spring
cylinder energy store is fully loaded and will
automatically re-apply the wheel brakes if the trailer
starts to roll backwards.
CAUTION: If the handbrake is not fully applied as
detailed above there is a danger that the trailer
could roll backwards!
To release:
Press the hand-brake push button fully home and
firmly press the handbrake lever back into the off
position (handbrake horizontal).
Automatic hand-brake lever (Fig. 5):
Ensure handbrake is fully applied (as
highlighted).This will ensure that the gas strut or
spring cylinder will automatically re-apply the wheel
brakes if trailer starts to roll backwards.
CAUTION: If the handbrake is not fully applied as
detailed above there is a danger that the trailer
could roll backwards!
To release:
Firmly push the handbrake lever back into the off
position (handbrake horizontal).
Hand-brake lever with spring cylinder and gas strut
(Fig. 6):
Ensure handbrake is fully applied (as
highlighted).This will ensure that the gas strut or
spring cylinder will automatically re-apply the wheel
brakes if trailer starts to roll backwards.
CAUTION: If the handbrake is not fully applied as
detailed above there is a danger that the trailer
could roll backwards!

Release:
Press the hand-brake push button fully home and
firmly press the handbrake lever back into the off
position (handbrake horizontal).
Servicing
Every 10 000 - 15 000 km or every 12 months:
Lubricate /grease all sliding and moving parts of the
overrun device as shown in Fig.7.
Recommended lubricant : General purpose grease to
DIN 51825 KTA 3K4
Servicing and care of hot dip galvanized parts:
The formation of white rust is only a surface coating
and has no adverse effect on the anti-corrosion
properties of galvanising. In order to minimise the
potential for the formation of white rust the following
precautions should be taken:
Ensure there is an adequate air circulation when
storing hot dip-galvanised parts.
After winter journeys it is recommended that surfaces
are washed with clean water.

Troubleshooting

Fault
Poor braking
Brake overheating during towing
Handbrake force low
Uncomfortable ride
Trailer brakes applied during
deceleration or downhill travel
Spare Parts
Replacement parts are safety critical parts. Should
parts other than original AL-KO spare parts be used
then warranty and product liability becomes void, i.e.
we as manufacturers will not be liable for any faults
that may occur following fitment of non AL-KO
spares. If repair work or servicing is required AL-KO
have a large network of AL-KO service stations
throughout Europe. A list of service centres can be
requested direct if required. Please bear in mind that
repairs should only be carried out by trained and
qualified workshops/personnel. To establish the
correct spare parts required for your overrun device
you should always quote the model and type of
overrun device in question along with the ETI No.
which is stamped into the overrun device housing
(See Fig. 8). The ETI information for the Euro overrun
can be found on the handbrake lever (see fig. 5a).
Please have this information readily available when
ordering spare parts.
Cause
Overrun shaft/linkages tight
Overrun shaft corroded
Damage to body housing
Hand-brake not fully released
Wheel fouls brake rod.
Gas strut defective
Axle shock absorbers defective
Overrun damper defective
Elimination
Grease transmission system and all
moving parts
Release hand-brake
Check transmission system operates smoothly
Check overrun lever moves freely
Slacken locking handle and repossition
accembly correctly.
Replace gas strut
Replace shock absorbers
Replace overrun damper
