16.1 Wheels/Brake System
1) Tire pressure should be set at 2.8 bar (ato) (40 psi) cold.
2) Check that all wheel lug nuts are tight. (Torque: 10 kgm / 100 Nm / 75 lb.ft.)
3) Ensure that all nuts, bolts and pins are secured on all exposed parts of the brake system (i.e.
all parts that move when the handbrake is pulled).
4) Check brake adjustment to ensure that trailer will stop its own weight and not push the tow
vehicle: First check brake shoes adjustment:
release hand brake completely
jack up one side of the trailer, so that the wheel(s) can be rotated by hand
tighten (clockwise) the 8 mm adjustment nut (on the rear (i.e., the inner side) of the
wheel hub), until the wheel gets very hard to turn
turn wheel in direction of travel to centre brake shoes
loosen again the adjustment nut only so much that the wheel turns freely
repeat above procedure for the other wheel(s)
check for uniform brake response in both sides of the trailer.
If trailer now pushes tow vehicle, then adjust (shorten) pull rod behind hand brake, so that
hand brake travel decreases. Hand brake should become active when pulled a few “clicks”.
5) Grease inertial brake system every 5.000 km (3,000 miles). Two grease fittings are located
by the hand brake. Use high quality grease.
16.2 Drop Weight Subassembly
1) Check that the rubber stabilizers for the load plate are not broken or otherwise damaged, or
loose. In case of an (optional) 4-segment loading plate, apply silicone oil or grease into the
4 segment swivel bearings periodically.
2) All exposed nuts and bolts should be periodically checked and retightened if necessary.
3) Inner parts of catch surfaces may be lubricated using a DRY spray lubricate such as Teflon
of silicon.
4) FWD ONLY: The two external weight guide rollers may be lubricated using a dry spray
lubricate such as Teflon or silicon.
