DA7000 SERIES GENERATORS — TIRE SAFETY
Make sure your tire valves have valve caps.
ALWAYS check tire pressure on tow vehicle and trailer
before towing. Check tire pressure at least once a month.
DO NOT overload tow vehicle. Check the tire
information and loading placard for safe allowable tire
loading conditions.
Tire Repair
The proper repair of a punctured tire requires a plug for the
hole and a patch for the area inside the tire that surrounds
the puncture hole. Punctures through the tread can be
repaired if they are not too large, but punctures to the sidewall
should not be repaired
. Tires must be removed from the
rim to be properly inspected before being plugged and patched.
Replacing Worn or Damaged Tires
Replace the tire before towing the trailer if the tire treads
have less than 1/16 inch depth or the telltale bands are
visible. Check inflation pressure weekly during use to insure
the maximum tire life and tread wear. A bubble, cut or bulge
in a side wall can result in a tire blowout. Inspect both side
walls of each tire for any bubble, cut or bulge; and replace a
damaged tire before towing the trailer.
Table 10 below will help pinpoint the causes and solutions of
tire wear problems.
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
replacedas complete units.
ALWAYS
wear safety glasses when
removing or installing force fitted parts
DO NOT attemp to repair or modify a
wheel. DO NOT install an inner-tube to
correct a leak through 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
NOTE
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.
