TRAILER INFORMATION ~
Maintaining the trailer ~
Galvanised trailers are coated in a galvanised finish. This chemical process bonds very hot liquid zinc to the trailer and its
components. The zinc covering forms a barrier that protects the steel under the zinc. The environment in which the trailer
is used, stored and maintained determines the level of deterioration of the zinc. In areas of high humidity, high salinity or
poor water quality, it is common for the zinc finish to deteriorate very quickly. A high level of care is required in these
environments.
Trailers must be washed thoroughly after use and stored in a dry, well ventilated area. Salt residues may drop onto your
trailer from the hull above while in storage. If this occurs, wash as soon as possible.
It is normal as the zinc surface ages that a white powder (calcium carbonate) forms on the galvanised components.
Calcium carbonate is normally evident in the low drainage points of the trailer where salt residues collect.
Couplings
Connect the coupling to the tow bar by placing the coupling directly over the ball, pull up the handle and let the coupling
slide down over the ball then release the handle letting it bottom out on the top of the coupling. Mechanical, hydraulic and
standard couplings need to be greased every six months or when there is no grease present on the shafts.
Safety chains
Connect the safety chain to the vehicle with D shackle supplied with the trailer. Do not use a padlock between the safety
chain and the car while travelling.
Jockey Wheels
When manoeuvring the trailer on either concrete, lawn or a soft surface, the jockey wheel should be in its wound down
position. This enables easier manoeuvring of the trailer.
Axles and springs
It is recommended that the suspension components be inspected at least twice yearly for any evidence of loose u-bolts,
bolts and corrosion or breakage of the leaf springs. Painted and galvanised suspension components should be sprayed
regularly with products such as lanolin based sprays.
Wheel bearings
Wheel bearings should be checked at least every 90 days and before putting the boat away for any lengthy period. They
should be replaced every 6 months depending on trailer use.
For a quick check, jack up the wheel and give it a wobble from side to side:
• If there is slack in the bearing you will need to retighten the axle hex nut and give the wheel a spin.
• If it is noisy you will need to change the bearings.
• If you re-assemble the hub and there is evidence of water, this will also render the bearings unfit for use and
require replacement.
Routinely check the wheel hubs whenever you stop for fuel or refreshments. If the hub feels abnormally hot, inspect the
bearings before continuing. On extended trips, carry spare wheel bearings, seals and races.
Brakes
If your trailer is braked, the braking system is a disc brake over-ride system with either mechanical (cable operated) or
hydraulic (fluid operated) brakes.
