coupling up (euro-overrun devices)
Fully retract Jockey Wheel inner tube so that it
locks against Jockey Wheel outer tube.
Slacken Jockey Wheel Clamp handle and raise
complete assembly through cutout in body
to its highest position (ensure it doesn’t come
into contact with the brake rod assembly), fully
tighten Jockey Wheel Clamp handle to ensure the
Jockey Wheel is firmly held in position (Fig. 45).
uncoupling (all types)
Secure caravan/trailer by chocking both wheels.
Apply handbrake fully. There are 4 different
handbrake systems (See Figs 42-46). With all
four systems please observe the following:
Handbrake lever With Gas strut (Fig . 42)
Ensure handbrake is fully applied (as
highlighted). This will ensure that the gas strut
will automatically re-apply the wheel brakes if
the trailer starts to roll backwards.
to release
Press the handbrake push button fully home
and firmly press the handbrake lever back into
the off position (handbrake horizontal).
caution: If the handbrake is not fully applied
as detailed above, there is danger that the
trailer could roll backwards!
caution: the brake rod must not be under
tension/bowed when the handbrake is
disengaged, otherwise the breakaway
mechanism will not function .
Handbrake lever With spring cylinder (Fig . 43)
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
caution: If the handbrake is not fully applied
as detailed above, there is danger that the
trailer could roll backwards!
automatic Handbrake lever (Fig . 44)
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 the trailer starts to roll backwards.
Caution: If the handbrake is not fully applied
as detailed above, there is danger that that the
trailer could roll backwards!
to release
Firmly push the handbrake lever back into the
off position (Handbrake horizontal).
Handbrake Lever With Spring Cylinder and Gas
Strut (Fig. 46), normally fitted to commercial units:
Ensure handbrake is fully applied (as
described). 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 danger that the trailer
could roll backwards!
to release
Press the handbrake push button fully home
and firmly press the handbrake lever back into
the off position (handbrake horizontal).
