III. INSTRUCTIONS FOR USE:
1) Safety Instructions:
WARNING: Before using your Little Giant Lifter Automatic,
please confirm the surfaces of the slab to be lifted are flat,
smooth, and free from dust, oil, or any kind of such harmful
substances which allow slipping for lifting.
a) For the Little Giant LifterAutomatic:
Cautions:
- Carefully consider and follow all the safety regulations and
applicable laws in your country for the operations.
- It is strongly recommended that only employees who are
highly trained or experienced are allowed to operate this device.
Safety rules and regulations must be strictly respected and
followed.
- Lift up the slab slowly. If the slab is not balanced, lower the
lifter, adjust the alignment and lift again.
- Before lifting any product, the Swivel Shackle should be
carefully inspected for its wear, any damage, cotter/snap pins
loosening / lost, or nut loosening. If the Shackle gets any
damage, it should not be used until repaired or replaced.
WARNINGS:
- Inspect the lifter carefully and thoroughly. If the rubber pads
of clamp plates are worn-out or damaged, do not use, replace
with new pads.
- This Little Giant Lifter Automatic is designed for lifting slabs
ranging from to 1 (10 to 50 mm). Determine the weight⅜” ¹⁵⁄₁₆”
of the slab to be lifted. Do not exceed the WLL (Work Load
Limit) shown on page 2.

- Make sure to check the rubber pads are free from dirt. Grease
and other substances that may reduce their effectiveness. Clean
the rubber pad surfaces by water. Then wait till dry and use the
device after.
- Do not lift wet slabs. The grip depends on friction. Lifting wet
slab may cause the rubber pads to lose their grips.
- No more than one piece should be lifted at any time.
- Position the lifter at the center of the slab to be lifted, so that the
load is balanced.
- Make sure that the slab is inserted to the full depth into the
opening of the lifter (Figure available at page 13).

2) Device usage:
Preliminary Safety Checks:
“Competent Person” shall check the following before each use.
WARNING:
Check the following before and after operations:
- The Little Giant LifterAutomatic is correctly installed/hung
in the right manner described in this paragraph and to be
operated in safe working conditions.
- The swivel shackle is correctly and securely installed and
tightened accordingly.
Automatic locking latch
Cam wheel
c) Automatic locking latch system:
- Automatic locking latch system consists of a cam wheel which
could be rotated when the device was lifted up to clamp the
stone slab.
- Please mind that this Automatic Locking System engages
Lifting pin with Main body to avoid Clamp plates to close for
clamping.
- In this condition, when lifting the Lifter, the Clamp plates are
free from clamping, so that the Lifter can be released from the
slab lifted before and to be moved to another.
- Make sure that no dust is inside the automatic locking latch,
regularly check and lubricate oil to ensure the proper operation.

Step 1: Hook the Little Giant Lifter Automatic to a forklift
boom or to a crane hook (figure 1.1).
Step 2: Use slab wedges* to make a gap between the outer slab
and the inner slab (figure 2.1).
Figure 1.1
Figure 2.1

Warning: Place the device at a safe place, then crane hook or
Forklift boom has to approach the lifter for installation.Avoid
lifting the lifter by hands in order to avoid dropping the lifter
unintentionally.
* Slab wedges (optional)

Step 3: Clamp the slab:
- Lowering the lifter to be perpendicular to the slab and place at
the center of the slab. (Figure 3.1)
Note: Position the lifter securely at the center of the slab so that
the load is balanced. Make sure that the slab is inserted in full
depth to the opening of the lifter (Refer the Appendix, page 13)
-Lift the stone slab slowly to ensure the weight balance. During
lifting, the locking latch system allows the Lifting pinautomatic
to keep clamping plates closed to grip the stone slab tightly.
Then, stone slabthe system releases the when the stone slab
touches the ground.
Note: If the clamp do not grip the slab firmly and securelyplates
when lifting, lower the lifter, recheck the status, and lift it up
again.

safety area while slab is being lifted or moved. Do not allow
yourself or anybody to go under the lifted slab.
Figure 4.1
Step 5: Remove the lifter out of the stone slab.
Lower the lifter slowly until the lifter and swivel shackle are
disengaged, the locking latch will lock the Lifting pin to the
Main housing automatically then the clamp plates are remained
open to release the slab. Then move the lifter away from the
slab.
Cautions:
- Before lowering the slab to the stand or rack, make sure that
there are no obstacles to interfere.
- If the lifter still grips the stone slab, do all the steps again by
moving up and down to unlock the locking latch.
