Trailer Jack
MasterCraft recommends using the trailer jack to lift the coupling
of a loaded trailer from the hitch ball. Rotate the trailer jack to the
vertical position and engage the locking pin before placing a load
on the trailer jack.
Like any mechanical assembly, the trailer jack requires
maintenance to continue to function properly. The drive gear and
the rack-and-pinion should be greased, and the caster and wheel
bearings should be oiled frequently.
triple-axle trailer, repeat the bleeding procedure on the rear axle(s)
brakes for a second time to assure purging of all air in the system.
7. Push down on the safety release bracket to ensure that the push
rod is in the released position.
8. After the bleeding is completed, recheck the fluid level in the master
cylinder. Fill the master cylinder reservoir to 1/8” from the bottom
of the threads on the reservoir cap. Do not overfill.
9. As a final check after bleeding is completed, stroke the push rod
and check to be sure the brake system is pressurized. This is done
by attempting to rotate a tire around. It is highly recommended to
check the function of the brakes prior to running down the road.
Attempt to back-up the trailer (preferably up and incline) without
the wiring harness connected. This should activate the brakes to
verify they are working as expected. If an incline is not available, and
with the wiring harness disconnected, attempt to back-up the trailer
against a wheel chock hard enough to slide the actuator rearward
into the frame and engage the brakes. Remove the wheel chock and
continue to back up to verify the brakes are engaging.
Important: Do not use brake fluid drained from the brake system
to refill the master cylinder reservoir as such fluids contain
contaminants from the system that may result in brake failure or
costly repairs.
Failure to swing up the trailer
jack and snap into towing
position before towing may
result in damage to the trailer.
To ensure the jack is locked in
the up or down positions, there
will be an audible “click” when
the locking pin is fully engaged.
Check that the jack is locked
by trying to move the jack out
of place.
