HYDRAULIC:
The optional hydraulic trailer jack is equipped with a pilot operated check valve to eliminate bleed down of the
hydraulic cylinder.
NOTE: FOR ELECTRIC OVER HYDRAULIC SYSTEMS, THE ENGINE NEEDS TO BE
RUNNING TO RAISE THE JACK.
MANUAL:
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.

Trailer tires may be worn out even though they still have plenty of tread left. This is because trailer tires have
to carry a lot of weight all the time, even when not in use. It is actually better for the tire to be rolling down the
road than to be idle. During use, the tire releases lubricants that are beneficial to tire life. Using the trailer tires
often also helps prevent flat spots from developing.
The main cause of tire failure is improper inflation. Check the cold tire inflation pressures at least once a week
for proper inflation levels. “Cold” means that the tires are at the same temperature as the surrounding air, such
as when the vehicle has been parked overnight. Wheel and tire manufacturers recommend adjusting the air
pressure to the trailer manufacturer’s recommended cold inflation pressure, in pounds per square inch (PSI)
stated on the vehicle’s Federal Certification Label or Tire Placard when the trailer is loaded to its gross vehicle
weight rating (GVWR). If the tires are inflated to less than the recommended inflation level or the GVWR of the
trailer is exceeded, the load carrying capacity of the tire could be dramatically affected. If the tires are inflated
more than the recommended inflation level, handling characteristics of the tow vehicle/trailer combination
could be affected. Refer to the owner’s manual or talk to your dealer or vehicle manufacturer if you have any
questions regarding proper inflation practices.
Tires can lose air over a period of time. In fact, tires can lose 1 to 3 PSI per month. This is because molecules
of air, under pressure, weave their way from the inside of the tire, through the rubber, to the outside. A drop in
tire pressure could cause the tire to become overloaded, leading to excessive heat build up. If a trailer tire is
under-inflated, even for a short period of time, the tire could suffer internal damage.
High speed towing in hot conditions degrades trailer tires significantly. As heat builds up during driving, the
tire’s internal structure starts to breakdown, compromising the strength of the tire. It is recommended to drive
at moderate speeds.
Statistics indicate the average life of a trailer tire is about five years under normal use and maintenance
conditions. After three years, replacing the trailer tires with new ones should be considered, even if the tires
have adequate tread depth. Some experts claim that after five years, trailer tires are considered worn out and
should be replaced, even if they have had minimal or no use. This is such a general statement that it may not
