Operating instructions

23
Storing
To reduce the possibility of contamination of
component parts of the AKS 3004 the stabilising
handle should be closed.
Towing ball
The automobile towing ball should measure 50mm
maximum and 49mm minimum diameter (DIN
74058). If the ball is below 49mm diameter it
should be replaced immediately.
Overrunning device
The device housing is packed with grease on
assembly, but will require periodic maintenance to
ensure smooth operation of the braking system.
i. Regrease the shaft bearings via the grease nipples
provided at 3000 mile intervals, and before storage.
ii. Ensure correct functioning of all pivot pins and
levers and oil regularly.
iii. Ensure correct functioning of handbrake ratchet
and oil regularly.
Jockey wheel
Lubricate wheel and screw thread periodically with
grease.
Brake linkage
All moving parts should be lubricated periodically to
ensure their satisfactory operation.
Corner steadies
The screw and pivot pins should be lubricated
periodically to ensure their satisfactory operation.
Braking system adjustment
(At 500 miles, then every 3,000 miles or 1 year)
i. Ensure the towing shaft with coupling heads is
pulled fully forward (g. 8).
ii. Release the handbrake to the fully off position.
If the handbrake will not go down the whole way
because of the fairing or any other obstruction; then
the fairing must be cut away and/or the obstruction
removed to achieve this desired position. It will not
be possible to set up the braking system properly
when the handbrake is not in the fully off position
(g .8).
iii. Jack up one side of the caravan (see Jack
Operation Instructions).
iv. Remove the inner plastic bung from the backplate
to expose the ‘starwheel’ adjuster access (gs. 8 &
9).
v. Always rotating the road wheel in the forward
direction – never backwards; adjust the starwheel
with a suitable screwdriver, in the direction of the
arrow embossed on the backplate until there is
resistance in the wheel rotation (g. 9).
vi. Slacken off the starwheel adjuster until the road
wheel turns freely in the forward direction (g. 9).
vii. Check the adjustment at the end of the brake
cable where it is secured to the abutment (bracket)
welded to the centre of the axle. When the inner
cable is pulled out it should extend between 5 and
8 mm (g. 8). (On tandem axles a double abutment
is tted to the front axle only).
viii. Repeat for other wheel or wheels.
ix. Ensure the balance bar (compensation) is being
pulled evenly. This bar (double on tandem axles)
should always be paralleled with the axle tube when
pulled (gs. 8 & 10). Adjust M8 lock and ball nuts, if
necessary, to achieve correct parallel position (g.
10).
x. Check the brake rod support bracket, (xed to
the oor) is supporting the brake rod evenly. The
brake rod must always run straight, never bent or
curved under any ttings. On tandem axles, using
the double balance bar, a brake rod support tube
(Part No. 228827) must always be tted on the
end of the brake rod, passing through the centre
aperture on the abutment.
