3 Month Check

After a 3month period, or approximately 400km of use, start at the front of the trailer and re-tighten all nuts and bolts. It is the nature of zinc

to be a very soft material and after a short period of time , the bolts and retainers work into the soft zinc and require retensioning. This will

retension any bolts and fasteners.

Couplings.

Connect the coupling to tow ball on the car 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 as shown in Fig 1. If the coupling handle does not

bottom out,

check the towball anti-rattle bolt on the front of the coupling is not screwed to far in and stopping the coupling from going

completely down over the ball.

Do-not get into the habit of using the spring loaded catch to hold the plunger in the up position when connecting to your vehicle as shown

in Fig 2. Around 80% of trailer users drive off with the coupling in this position, it then can come off the ball , drops down on to the trailers

safety chain and does a lot of damage to the towing vehicle. Not to mention the safety aspect of the situation.

Mechanical, hydraulic and standard couplings as shown in Fig 2 & 3. need to be greased at the points arrowed every six months or when

there is no grease present on the shafts, at the same time all the bolts and nuts need to be checked for tightness.

Connect the safety chain to the vehicle with "D" shackle supplied with the trailer, do not use a key pad lock between the safety chain and

the towing vehicle while travelling.
