Socket extension.
Things to remember:
Do not tighten bolts until they are all correctly fitted.
Most nuts are captive nuts to speed up assembly.

1. Start with the floor pan upside down and fit the axle to the floor pan.
2. Fit the drawbar to the axle.
3. Attach the drawbar to the floor pan.
4. Fasten the light bar to the floor pan using the single bolt in the middle.
5. Attach the cables to the lights.
6. Fasten the wheels on.
7. Tighten all bolts under the trailer except the centre bolt on the light panel.
8. Turn the trailer the correct way up.
9. Fit a side panel.
10. Fit the front panel.
11. Fit the other side panel.
12. Fit the tailgate.
13. Fit the mudguards.
14. Tighten all Bolts.
Please note: Due to vibration bolts can rattle loose, all bolts MUST be checked after 60 miles.
It is also recommended to check lights, couplings, wheels, and wheel bearings BEFORE every long journey.
1. Start with the floor pan upside down and fit the axle to it.
Fit the axle to the floor pan
There are pre-drilled holes on each side of the floor pan to make this easier. Use a 17mm socket to tighten these four bolts.
2. Remove the bolt from the drawbar, then attach the drawbar to the centre support of the axle.
Connect the drawbar to the axle

Thread the two colored wires through the drawbar before slotting it into the centre support of the axle. The large bolt from the drawbar passes through both parts and is secured with a lock nut. You will need a 17mm spanner and socket to tighten this. Remember this is the pivot point for the trailers tipping feature, so don’t over tighten it.

3. Attach the drawbar to the floor pan using the tipping bracket.

The tipping bracket must be fitted to the

underside of the floor pan as shown below. At the centre point of the front edge are pre-drilled holes where it mounts. A 13mm socket/spanner is required for this.

4. Fasten the rear light bar to the floor pan.
Fit the rear light panel

It helps to fit the rear light bar at an angle and then straiten it up when you get it into the correct position. At this time a single dome head screw though the centre of the bar will hold it in place.

5. Attach the colour coded cables to the corresponding sockets on the reverse of the rear light bar. Each socket is marked with a coloured sticker.

Slot the cables into the sockets and then twist the coloured sheath clockwise to lock it in place. The cable will only slot into the socket in one direction, so don’t force it.

6. Fit the wheels.
Wheel nuts face rounded ends inwards

Remember that the rounded ends of the wheel nuts face inwards. If they are fitted facing outwards you will not be able to tighten them up correctly. A 17mm socket or wheel wrench is needed here.

7. Tighten all bolts under the trailer except the centre bolt on light panel.
8. Turn the trailer the correct way up. This may require two people.
9. Fit a side panel. It is easiest to mount it at the back first and then lower the front into position.
Fit the side panels back end first

Locate the small stud on the rear of the side panels. There is a small hole on both sides of the light bar, one for each panel. Hook this stud into the hole before lowering the side panel into position.

Fit side panel from back to front
Lower the front of the side panels into position.
Side panel in place

A 13mm bolt at the front and rear of the side panel will hold it in place. A smaller 10mm bolt must also be fitted underneath the rear edge where the side panel hooks into the light bar.

10. Slot the front panel into place, do not bolt it down completely at this stage.

11. Fit the other side panel in the same way as before.
12. Fit the tailgate.
Tailgate hinge apart
The tailgate hinge simply slides together.

13. Fit the mudguards.
Fit mudguard reinforcement plate
Remember to fit the mudguard reinforcement plates. These prevent bolt heads from pulling through the thin metal of the mudguards.
Fit the mudguards

The mudguards mount onto pre-drilled holes in the side of the floor pan, located just above the wheels. A 13mm socket with extension is needed to reach these bolts.

14. Tighten all Bolts.

Again, remember to perform a thorough check of all nuts, bolts, wheels, bearings and lights after the first 60 miles. Vibrations can cause slackening of nuts and bolts in new trailers, so it is very important you perform this check.
