How to operate TrestleJacks:
Example: Lifting one side of an axle of a heavy load trailer:
1. Identify an even and hard surface for the lifting process. Always be aware of safety and your
surroundings.
2. Apply parking brakes, turn off ignition, chock the wheels and apply trailer brakes before any
preparation work is started.
3. Place the TrestleJacks 30T TJ470 unit in the loading position underneath the trailer axles as
close to the troubled wheel as possible. Position the jack cup as close to the axel as possible
with the least amount of play, this will ensure the Jacks do not slide while lifting. Ensure that
the TrestleJacks cup is positioned against the axle utilizing a clear space that is free from axle
mounted components. Move any wiring out of the way that could potentially be damaged
during the lifting process.
4. In the event where the entire axle needs to be lifted, two TrestleJacks per axle must be used

are secured and before axle lifting procedure starts.
