LS600 PUMP —TRAILER SAFETY GUIDELINES

WARNING - Flying Objects

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.

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.

NEVER! use an pneumatic air gun to tighten wheel lug nuts.

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. DONOT 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.

TABLE 8. TIRE TORQUE REQUIREMENTS

Wheel Size	First Pass	Second Pass	Third Pass
	FT-LBS	FT-LBS	FT-LBS
12"	20-25	35-40	50-65
13"	20-25	35-40	50-65
14"	20-25	50-60	90-120
15"	20-25	50-60	90-120
16"	20-25	50-60	90-120

WARNING - Lug Nut Tightening
Over-tightening lug nuts will result in breaking the studs
or permanently deforming the mounting stud holes in
the wheels.
WARNING - Lug Nut Inspection
Lug nuts are prone to loosen after initial installation,
which can lead to death or serious injury. Check all
wheel lug nuts periodically.	Figure 59. Wheel Lug Nuts Tightening
