6.DO NOT slid the load on or off the table. The lift may move allowing the load to fall. SEVERE PERSONAL INJURY and PROPERTY DAMAGE could result.
7.DO NOT use lifter with unstable, unbalanced or loosely stacked load. Unbalanced loads may become unstable and fall. SEVERE PERSONAL INJURY and PROPERTY DAMAGE could result.
8.ALL lifter service must be performed by qualified personnel only.
9.ALWAYS keep feet, hands and fingers away from casters, load wheels and all moving components. SEVERE INJURY could result.
10.ALWAYS perform maintenance and inspections with lifter unloaded.
11.Prolonged continous working might cause damage of power pack.
12.Stop operation if temperature of hydraulic oil is too high.
The lifter is NOT waterproof and is intended to be used in a dry environment.
NOTE
The table is equipped with an aluminum guard to avoid accidental danger.
If aluminum guard strikes an object while the table lowers, stop operation and check the lift table. After making sure no any abnormality, strike the UP button slightly and then the electric system will function as before.
3. DAILY INSPECTION
Daily inspection is effective to find the malfunction or faulty on the lifter. Check the lifter on the following points before the operation.
CAUTION |
DO NOT use lifter if any malfunction or faulty is found. |
(1)Check scratch, bending or crack on the lifter.
(2)Check smooth movement of the wheels.
(3)Check if there is oil leakage.
(4)Check vertical creep of table.
(5)Check the function of brake.
(6)Check if all the bolts and nuts are tightened firmly

How to use thebrake.
CAUTION |
Brake lift table when not moving it in order to prevent sudden movement. |
The brake is equipped with the swivel caster on the right side.
(1) Braking the wheel, press the brake pedal.
(2) Releasing the brake, lift up the brake pedal.
6. LIFTING UP FORKS
CAUTION |
1.DO NOT overload lifter. Stay within its rated capacity. 2.Prolonged continous working might cause damage of hydraulic power pack. 3.Step operation if temperature of hydraulic oil is too high. |
Push the button “UP”and the table lift up.
7.LOWERING TABLE
CAUTION |
DO NOT lower table with load too fast and stop suddenly. Impact load could be created and lifter could be damaged. |
Push the button DOWN and the table lower.
8.MOVING THE LIFTER
WARNING |
DO NOT move lifter on slope or inclined surface, otherwise lifter become uncontrollable and create danger. |
(1)Make the load stable to prevent it to fall.
(2)Lower the table down.
(3)Release the brake and move the lifter.
CAUTION |
KEEP watching the condition of load. Stop operating lifter if load become unstable. |
9.CHARGING THE BATTERY
(1)Check the quantity of Battery fluid. If it is insufficient, add the battery solution according to battery operation manual.
(2)Disconnect the battery socket.
(3)Connect the charging port of battery socket to the battery charger.
10.REGULAR INSPECTION
Perform the regular inspection for the safety operation.
(1)Check the items expressed in daily inspection (daily).
(2)Lubricate with grease the guides where roller moves. Also, lubricate the grease nipples. (Every month)
(3)Lubricate all the pivoting points and axles. (Every 6 months)
(4)Replace the hydraulic oil for the first time: Accumulated working ten hours’
(5)Replace the hydraulic oil. (Every 12 months)
