400Q Stabiliser Fitting Instructions

Adjustments.
1) Once fitted check that the springs are completely retained in the plastic slippers and
do not catch any part of the caravan or trailer when vehicle is on full lock.
2) The stabilisers are factory set but may need adjustment after use.
3) To adjust the friction damper assembly you will require the
following tools:
●A set of bathroom scales or suitable spring balance.
●Two open ended 19mm spanners.
Note. Adjustment is carried out with quick release locked i.e. pressure applied to friction
discs.
IMPORTANT!
Please DO NOT use torque wrench as the torque needed on the 12mm adjusting bolt and nut (4) is very small.
4) Insert the damper pivot bracket (3) into the slot in the car plate (1) and secure with locking stud(2).
5) Apply the scales to the end of the spring arm and push. You are looking for a reading on the scales of
approximately 75lbs (33kg). It is emphasised that this is NOT a torque figure but the horizontal push/pull force at the
end of the spring arm.
6) Adjustment is made by releasing the thin lock nut on the 12mm centre bolt and tightening up the special type lock nut
until the appropriate reading is obtained on the scale. Finally, firmly lock up the special nut and thin lock nut together
using the two spanners. Take care not to move the special nut on the bolt or you may lose the correct setting. Check
tightness of the thin lock nut after 50 miles.
7) DO NOT USE ANY OTHER METHOD FOR CHECKING THE STABILISER.
If you have any doubt about servicing your stabiliser please contact your nearest dealer or telephone Bulldog for
assistance.

WARNING!
After fitting and prior to commencing your journey, please check tightness of the locking stud holding the
stabiliser into the car bracket. A secondary safety and security feature of the Bulldog stabiliser is the provision of
a hole in the end of the damper pivot plate (3). This is to facilitate the use of a padlock (not supplied).
When Boarding Ferries or Off Road on Uneven Ground.
It is advisable to remove stabilisers to avoid damage to the spring arm.
Heavy Trailers.
When reversing very heavy trailers it is recommended that the stabilisers are removed prior to carrying out tight manoeuvres.
Failure to do so may result in damage to the stabiliser or car plate.
When Not In Use.
Remove locking stud. Apply grease in the thread car bracket and fit Red Cap. To remove cap just unscrew.
