b) Secure the chain into the pump block using cotter pins and the axle.
4.4.2 Securing the chain into the chassis groove:
Using two washers, put the bolt into the the middle of thread groove and then tighten the nut.
4.4.3 Clip the chain on the handle.
4.4.4. Once assembled, the lift table will activate, lift and lower easily when the lift handle is released. If the
table will not lower, please adjust using steps a) or b)
a) Loosen the up and down nuts, pull the release wire up for a snug fit, and then tighten the nuts until the
table lowers smoothly.

6-1. How to use the brake.
CAUTION
Ensure that the brake for the lift table is set when it is not in use to prevent sudden movement.
The brake is located on the right side of the swivel caster.
(1) To set the brake, press the brake pedal.
(2) To release the brake, lift up the brake pedal.
6-2. Lifting the table
WARNING
1. DO NOT overload the lift table; ensure the load is within its rated capacity.
2. All loads must be distributed evenly on at least 80% of the table area. DO NOT set loads to the side
or ends of the lift table surface.
Press the lifting pedal several times until the table reaches the desired position.
The table does not elevate once it has reached the highest possible position even if the lifting pedal is
continually pressed.
The table lowers slightly after reaching the highest position.
NOTE:
The hydraulic cylinder is designed to hold the table. As is the nature of the hydraulic system, the table lowers
very slowly over an extended period of time, Please note the table will not stay at the same position
indefinitely.
6-3. Lowering table
