9.2.4 SPARE WHEEL

The spare wheel is located on a bracket on
the side of the trailer. This is of the same
type as the wheel/tyres fitted to the trailer
and is secured in place using two of the
standard wheel bolts. These bolts should be
fitted opposite to each other, e.g. Position
1&2 or 3&4.
9.3 BRAKES & COUPLING
Your trailer is fitted with Knott brakes and
coupling. Supplied within the user manual
pack is a Knott Maintenance & Servicing
information leaflet which covers the
following maintenance procedures:
• Replacing brake assembly complete.
• Replacing brake shoes.
• Brake adjustment.
• Replacing brake cable (Bowden cable).
• Replacing breakaway cable.
• Replacing coupling head & bellow.
• Replacing the coupling damper.
These procedures must be carried out by
competent persons. If you have any doubts
about your ability to complete any
of the procedures we recommend
these tasks are performed
by your local distributor.
Brake drum removal and replacement
requires the axle nut to be removed and
refitted. A new axle end nut must be fitted
every time it is removed and refitted.
Tighten to a torque of 350Nm and lock
into both sides of the stub axle groove as
shown adjacent.
