See manufacturer’s documentation for maintenance inspection intervals,
fluid type and requirements.
❑ Check brakes for proper operation.
Any problems with the brakes must be repaired immediately. Do not use
the trailer.

❑ Inspect electrical cable harnesses to ensure they are in good condition
and that all connectors are correctly assembled and secured - repair and /
or replace accordingly.
Operate tail lights and turn signals and observe for proper operation.
Replace bulbs as needed.
Tires / Wheels
Also see SAFETY Section, heading 1.4 “Trailer Assembly” on page 19.
❑ Check tires for cuts, incorrect pressure, embedded foreign material or
excessive tread wear. Note any apparent loss of air. Repair and / or
replace accordingly.
See manufacturer’s documentation for pressure requirements.
❑ Inspect wheels for missing lug nuts and ensure they are torqued to manu-
facturer’s specifications.
Lug nuts are prone to loosen after being first assembled. Death or seri-
ous injury can result. Check lug nuts for tightness on a new trailer and
after remounting a wheel at 10, 25 and 50 miles.

Trailer
Also see SAFETY Section, heading 1.4 “Trailer Assembly” on page 19.
❑ Check the hitch ball, pintle hook and lunette eye for wear, corrosion and
cracks. Replace if worn, cracked or corroded.
❑ Check the break-away system regularly. An ineffective break-away sys-
tem can result in a runaway trailer, if the coupler or ball hitch fails, leading
to death or serious injury.
❑ Check the safety chain for integrity, not damaged, opened links, etc. A
defective safety chain can result in loss of control of the trailer and tow
vehicle leading to death or serious injury, if the trailer uncouples from the
tow vehicle.
