2.14 BREAKING-IN A NEW TRAILER
Retighten Lug Nuts at First 10, 25 & 50
Miles
Wheel lugs can shift and settle quickly after being first
assembled, and must be checked after the first 10, 25
and 50 miles of driving. Failure to perform this check
could result in a wheel coming loose from the trailer, caus-
ing a crash leading to death or serious injury.
CHECK LUG NUTS FOR TIGHTNESS ON A NEW TRAILER OR
WHEN WHEEL(S) HAVE BEEN REMOUNTED AFTER THE FIRST
10, 25 AND 50 MILES OF DRIVING. REFER TO SECTION 4 FOR
TORQUE SEQUENCE AND TORQUE VALUES.
Adjust Brake Shoes at First 200 Miles
Brake shoes and drums experience a rapid initial wear.
The brakes must be adjusted after the first 200 miles of
use, and each 3,000 miles thereafter. The brakes are
adjusted manually. (Refer to section 4 for manual brake
adjustment).
Synchronizing the Brake Systems
Trailer brakes are designed to work in synchronization
with the brakes on the tow vehicle. Do not use either brake
system alone to stop the combined tow vehicle and trailer.
When the tow vehicle and trailer braking systems are syn-
chronized, both braking systems contribute to slowing,
and the tongue of the trailer will neither dive nor rise
sharply.
ROAD TEST THE BRAKES IN A SAFE AREA AT NO MORE THAN
30 M.P.H. BEFORE EACH TOW.
To ensure safe brake performance and synchronization,
read and follow the axle/brake and the brake controller
manufacturers’ instructions. If you do not have these
instructions, call your dealer or JLG to obtain a copy.
A hard stop is used to:
a. Confirm that the brakes work.
b. Confirm that the trailer brakes are properly syn-
chronized with the tow vehicle brakes.
