PARKING
AUTO REVERSING BRAKED TRAILERS
a)
Apply handbrake fully (if energy stores is fitted to rear of coupling then apply further
pressure to the handbrake to compress the spring which is fitted within the energy
store component). This ensures that should brake roll-off occur when a trailer is
parked with the rear facing down an incline that the brakes will automatically be re-
applied. If the unit is fitted with a power assisted handbrake, then no further action
is required as the handbrake will automatically take up any further movement
should roll-off start to occur when parked on a slope.
b)
If towing eye is fitted instead of ball head, remove pin from towing jaw and reverse
towing vehicle until eye enters jaw. Then replace pin and locking pigtail or other
securing device.
c)
Continue to wind up jockey wheel until fully retracted and wheel is no longer free to
rotate. Loosen jockey clamp and raise jockey wheel up into chassis with wheel
facing rearwards and re-tighten clamp firmly ensuring wheel is well clear of brake
linkage.
Please remember brake linkage must be free to move fully during overrun braking
when on the road. Also handbrake so that breakaway cable can apply brakes if
trailer should part company with towing vehicle.
d)
Check condition of breakaway cable. If frayed or kinked at all replace immediately
before use. Then connect breakaway cable to towing attachment on towing
vehicle. The cable must be free of knots.
e)
Check the load is distributed to give the correct nose weight for the coupling (max
allowable HU2
– 75kg, all HU3 units – 100kg, HU12 – 120kg) a positive nose
weight is strongly recommended to ensure stable towing. Also ensure nose weight
is within limit of towing vehicle.
f)
If towing with a car transporter vehicle or any other vehicle, which has a long rear
overhang, extra forces can be applied to the coupling and towing device causing
rapid wear and damage. Please consult our Sales Department.
g)
Loosen jockey clamp and lower jockey wheel to ground. Firmly re-tighten clamp
(by hand). Press back trigger with thumb and lift handle on coupling head. At the
same time raise front of trailer by use of jockey wheel until head is fully clear of ball
on towing vehicle.
h)
Disconnect breakaway cable from towing vehicle.
i)
Drive towing vehicle clear of trailer. (In the case of a coupling fitted with an eye
follow above instructions except in respect of the final disconnecting of the towing
vehicle in which case the instructions supplied with the towing jaw of hook should
be used accordingly).
j)
As extra security it is strongly recommended that the wheels of the trailer should be
chocked as an additional safeguard.
