Operation
Note: The scissor lift table comes pre-assembled
and ready to use. However, during transit air may
have seeped into the pump. To bleed air out of the
hydraulic system, raise and lower the table several
times to work any air bubbles out of the pump.
1. The table is raised by pumping the foot lever
(B, Figure 1).
2. To lower the table, slowly pull the release lever
fully. This allows the table to lower in a slow,
controllable manner.
3. Before loading, always lock the caster brake
by pressing the lock (A, Figure 1).
Folding Handle
1. Lower the table.
2. Push the rod (C, Figure 1) back.
3. Fold the handle flat across the table.
Maintenance
1. Lubricate each friction point monthly with #2
tube grease.
2. Check the movement and wear of wheels.
3. Check for oil leakage from the hydraulic
cylinder. Add hydraulic oil as needed.
4. Always store with table in lowered position
when not in use.
