LS600 PUMP — TRAILER SAFETY GUIDELINES
Lug Nut Torque Requirements
It is extremely important to apply and maintain proper wheel
mounting torque on the trailer. Be sure to use only the
fasteners matched to the cone angle of the wheel. Proper
procedure for attachment of the wheels is as follows:
1. Start all wheel lug nuts by hand.
2. Torque all lug nuts in sequence. See Figure 59.
DO NOT
torque the wheel lug nuts all the way down. Tighten each
lug nut in 3 separate passes as defined by Table 9.
3. Check to see if the lug nuts are tight after the first 10,
25 and 50 miles of driving and before each tow thereaf-
ter.
Wheel Rims
If the trailer has been struck, or impacted, on or near the
wheels, or if the trailer has struck a curb, inspect the rims
for damage (i.e. being out of round); and replace any
damaged wheel. Inspect the wheels for damage every year,
even if no obvious impact has occurred.
Wheels, Bearings and Lug Nuts
A loose, worn or damaged wheel bearing is the most
common cause of brakes that grab.
To check wheel bearings, jack trailer and check wheels for
side-to-side looseness. If the wheels are loose, or spin
with a wobble, the bearings must be serviced or replaced.
Check inflation pressure weekly during use to insure the
maximum tire life and tread wear. Most trailer axles are
built with sealed bearings that are not serviceable. Sealed
bearings must be replaced as complete units.
ALWAYS
wear safety glasses when
removing or installing force fitted parts
DO NOT
attempt to repair or modify a
wheel.
DO NOT
install an inner-tube
to correct a leak through the rim. If
the rim is cracked, the air pressure in the inner tube
may cause pieces of the rim to explode (break off) with
great force and cause serious eye or bodily injury.
WARNING
-
Flying Objects
Lug nuts are prone to loosen after initial installation,
which can lead to death or serious injury. Check all
wheel lug nuts periodically
.
WARNING
-
Lug Nut Inspection
NEVER!
use an pneumatic air gun
to tighten wheel lug nuts.
Over-tightening lug nuts will result in breaking the studs
or permanently deforming the mounting stud holes in
the wheels.
