8.0 Operating instructions
Important: During shipment and handling, air
sometimes gets into the hydraulic system causing
poor lifting performance. Before initial operation,
purge any air from system by fully opening pump
release valve (turn handle counter-clockwise).
Then, while holding saddle down, pump handle
rapidly several times.
8.1 Raising the jack
1. Close release valve by turning handle
clockwise until resistance is felt. Do not over
tighten.
2. Place jack directly under object to be lifted,
and pump handle to raise saddle to contact
point. Make sure saddle accepts weight firmly
and centrally.
3. Check positioning under slight load to confirm
jack or load will not slip, or move suddenly.
4. Raise jack by pumping handle until desired
height is reached.
5. After lifting, secure and transfer load to jack
stands or other appropriate means. Do not
use jack as the only means of support.
8.2 Lowering the jack
Slowly turn handle counter-clockwise. Speed of
descent is controlled by amount release valve is
turned.
9.0 Maintenance
Store jack in a safe and dry environment, away
from children or unauthorized personnel. Always
store jack in fully lowered position, with handle in
upright position.
