DA7000 SERIES GENERATORS — TRAILER SAFETY
TIRE SAFETY
Unsafe Tires, Lug Nuts or Wheels
Trailer tires and wheels are more likely to fail than car tires
and wheels because they carry a heavier load. Therefore, it
is essential to inspect the trailer tires before each tow.
If a tire has a bald spot, bulge, cuts, is showing any cords,
or is cracked, replace the tire before towing. If a tire has
uneven tread wear, take the trailer to a dealer service center
for diagnosis.
Uneven tread wear can be caused by tire imbalance, axle
misalignment or incorrect inflation.
Tires with too little tread will not provide adequate tracking
on wet roadways and can result in loss of control, leading to
death or serious injury.
Improper tire pressure causes an unstable trailer and can
result in a tire blowout and loss of control. Therefore, before
each tow you must also check the tire pressure. Tire
pressure must be checked when tires are cold.
Allow 3 hours cool-down after driving as much as 1 mile at
40 m.p.h. before checking tire pressure. NOTE: Trailer tires
willbe inflated to higher pressures than passenger vehicle
tires.
Since trailer wheels and lug nuts (or bolts) are subjected to
greater side loads than automobile wheels, they are more
prone to loosen. Before each tow, check to make sure they
are tight.
The proper tightness (torque) for lug nuts is listed in the lug
nut tightening section of this manual. Use a torque wrench
to tighten the lug nuts. If you do not have a torque wrench,
use a lug wrench (from your tow vehicle) and tighten the
nuts as much as you can. Then have a service garage or
trailer dealer tighten the lug nuts to the proper torque.
Metal creep between the wheel rim and lug nuts will cause
rim to loosen and could result in a wheel coming off,
leading to death or serious injury.
Tighten lug nuts before each tow.
WARNING - Lug Nut Tightening
Lug nuts are also prone to loosen after first being assembled.
When driving a new trailer (or after wheels have been
remounted), check to make sure they are tight after the first
10, 25 and 50 miles of driving and before each tow
thereafter.
Failure to perform this check can result in a wheel parting
from the trailer and a crash, leading to death or serious
injury.
Lug nuts are prone to loosen after initial installation, which
can lead 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.
WARNING - Lug Nut Loosening
Improper lug nut torque can cause a wheel parting from
the trailer, leading to death or serious injury.
Be sure lug nuts are tight before each tow.
WARNING - Improper Lug Nut Torque
Improper tire pressure can result in a blowout and loss of
control, which can lead to death or serious injury.
Be sure tires are inflated to pressure indicated on side
wall before towing trailer.
