iTF series manual hydraulic lift table is new type of scissor lift table. It is is the fully manual table lifter that provides assistance in lifting material so that the task could be done in a safer way even when lifting heavy materials. This unit mobile scissor lift table has single scissor and double scissors. New hydraulic system increases safety and protects your goods, tepless rate of lowering system remains irrespective of the weight of the load.
Two swivel castors with brake can help to stop the manual hydraulic platform truck at a certain position during loading and unloading, preventing the danger caused by the platform truck sliding away. Front wheel with anti-collision frame can prevent contact objects from being injured.
The manual hydraulic lift table has models: iTF15, iTF30, iTF50, iTF75, iTF100, iTFD35 and iTFD70. This hand lift table truck is manual moving and manual lifting. iTF15, iTF30 are foldable handle and the others are fixed handle.
PLEASE CHECK"Electric scissor Lift Table" IF YOU NEED ELECTRIC MODEL.
- It is necessary to repeatedly step on the pedal to make the cargo rise to the required height with the work surface;
- Slowly lift the handle, open the check valve to make the work surface slowly descend;
- Please turn on the brake before moving the lift table.

Attention and maintenance:
- The unit manual table lifter is specially designed and operated by the user;
- It is strictly forbidden to use overload or unbalanced load;
- During the operation, it is strictly forbidden to stand on the platform;
- It is strictly forbidden to place your hands and feet under the lowering table;
- When the goods are being loaded, the brakes should be braked to prevent the hydraulic lift table from moving;
- The goods should be placed in the center of the countertop and placed in a stable position to prevent slippage;
- When the cargo is lifted, the platform truck cannot be moved;
- When moving, be sure to hold the handle to move the lift table;
- Use the manual lift table on a flat, hard ground, and do not use it on slopes or bumps.
After the operation is completed, the goods should be unloaded to avoid deformation of the platform truck caused by heavy load for a long time;
When maintaining, be sure to support the scissor arm with the support rod to avoid the lowering of the table during the work of the operator.
Common Failure and Solutions of the manual lift table :
（一）The mobile lift table is weak or unable to lift
Reasons and elimination methods:
- Cause: overload
Elimination method: reduce the load can be eliminated
- Reason: the oil return valve is not closed
Elimination method: tighten the return oil valve can be eliminated
- Reason: the one-way valve of the manual pump is stuck and fails
Elimination method: unscrew the oil pump valve port bolt, overhaul, clean, replace clean hydraulic oil can be eliminated
- Reason: manual pump, gear pump serious oil leakage
Elimination method: replace the oil pump seal ring can be eliminated
Reason: gear pump damage, hit the oil without pressure
Elimination method: replace gear pump can be eliminated
- Reason: insufficient hydraulic oil
Elimination method: add enough hydraulic oil to eliminate
- Reason: circuit break
Exclusion method: check the button contactor and fuse can be excluded
- Reason: clogged filter
Elimination method: replacement or cleaning can be eliminated
- Reason: support valve or electromagnetic reversing valve action failure, there are two cases: A, electromagnetic coil input voltage is less than 220V.B. solenoid coil burns out c. valve core is stuck
Elimination method: maintenance or replacement can be eliminated
（二）The lifting platform of the mobile lift table drops naturally
Causes and elimination methods
- Reason: one-way valve discharge
Exclusion method: check the one-way valve in the valve group.If there is dirt on the sealing surface of the one-way valve. Clean check valve.
- Reason: the descending valve is not tightly closed
Elimination method: check whether there is electricity in the descending valve, if there is no electricity, remove the fault of the descending valve itself or replace the descending valve.The slide valve of the descending valve must be kept clean and movable.
- Cause: leakage in the oil cylinder
Elimination method: replace cylinder seal
（三）The lifting platform of the mobile lift table does not descend
- Reason: the descending valve fails
Elimination method: in the case of pressing the drop button, check whether the drop valve has electricity.If there is no electricity, try to eliminate it.If there is electricity, remove the falling valve itself fault, or replace the falling valve.The slide valve should be kept clean and lubricated.
- Reason: the descending speed control valve is out of balance
Elimination method: adjust the control valve of falling speed, if the adjustment is invalid, replace the new valve.
