The pintle lock lever must be able to rotate freely
and automatically snap into the latched position.
Oil the pivot points, sliding surfaces, and spring
ends with SAE 30W motor oil. Keep the ring
pocket and latch mechanism clean. Dirt or
contamination can prevent proper operation of the
latching mechanism.
When replacing a pintle, the load rating must match
or exceed the GVWR of the trailer.
8.2.7 Landing Leg or Jack
If a grease fitting is present, you must use a grease
gun to lubricate the jack mechanism. Grease the
gears in the top of hand-cranked jacks once a year,
by removing the top of the jack and pumping or
hand packing grease into the gears.
8.2.8 Lights and Signals
Before each tow, check the trailer taillights,
stoplights, turn signals and any clearance lights for
proper operation.
^ WARNING
To avoid collisions, taillights, stoplights
and turn signals must work.
8.2.9 Accessory Battery
Your trailer may be outfitted with an accessory
battery that operates lighting, electric landing gear,
slide-outs or other accessories. An accessory
battery may be kept charged either by the tow
vehicle or by the generator or shore power. See the
manual for the accessory battery.
A disconnect switch may be provided to disconnect
the accessory battery when you do not plan to be
using the trailer for an extended period, such as
seasonal storage. If there is no disconnect switch,
then remove the cables from the battery terminals.
The accessory battery must be kept in a charged
condition during storage. The battery could freeze
and break if it becomes discharged.
8.2.10 Tires
Before each tow, be sure the tire pressure is at the
value indicated on the Certification / VIN label.
Tire pressure must be checked while the tire is cold.
Do not check the tire pressure immediately after
towing the trailer. Allow at least three hours for a
tire to cool, if the trailer has been towed for as much
as one mile. Replace the tire before towing the
trailer if the tire treads have less than 2/32 inch
depth or the telltale bands are visible.
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.
^ WARNING
Worn, damaged or under-inflated tires can
cause loss of control, injury and damage.
Check tires before each tow.
8.2.11 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.
Never install aftermarket wheels or lug nuts on
your trailer
. Use only original equipment wheels
and lugs nuts. Aftermarket wheels and lug nuts
may not meet the load carrying requirements,
pressure capacity and offset as the original
equipment.
8.2.12 Wheel Liners (Simulators)
Your trailer may be equipped with wheel liners
(simulators). See figure 8-2. To remove the liners
to access the wheel lugs:
1.
Locate the two removable jam nuts (1). These
nuts will have a crimp mark on every other hex
and are 180 degrees apart.
2.
Remove the jam nuts. Do not use power tools
on jam nuts.
3.
Remove the hub cover (2), wheel liner (3),
spacers (4) and stud extenders (5).
