D. Pinch Points.
1. Due to the mechanical nature of the Multilift®, extreme care must be taken
to avoid placing hands, limbs, hair, or clothing on or near the lifter while in
operation.
2. Extreme care must be taken while adjusting the legs of the lifter. Keep
fingers, clothing, etc. clear of the gap(s) formed between the leg and core
structures.

Section IV. Setup.
A. Check the lifter for any signs of damage incurred during shipping.
B. Record model and serial #of assembly and components.
C. Check all bolts for snugness.
D. Attach Multilift® to hoist.
1. Use as few rigging components (shackles, slings, chain, etc.) as possible.
2. ALL RIGGING COMPONENTS MUST HAVE A WORKING LOAD
LIMIT THAT IS EQUAL TO OR GREATER THAN THE COMBINED
WEIGHT OF INTENDED LOAD PLUS THE KENLIFT®.
3. UNDER NO CIRCUMSTANCES SHOULD ANY COMPONENT USED
AS RIGGING TO THE MULTILIFT® BE OF A RATED CAPACITY
LESS THAN THAT OF THE KENLIFT®.
4. DO NOT RIG UNPROTECTED NYLON SLINGS OR WIRE ROPE
DIRECTLY THROUGH LIFT BAIL.
5. IF USING EQUIPMENT OTHER THAN A CRANE: USE RIGGING OF
SUFFICIENT LENGTH TO PREVENT CONTACT BETWEEN
MULTILIFT® AND EQUIPMENT.
Section V. Grip Adjustment
CAUTION: The procedures that follow are intended as guidelines. They are to be
carried out by qualified mechanics possessing knowledge of general procedures
and practices involved with the maintenance of heavy machinery.
IMPORTANT: Wear appropriate protective clothing and personal safety
equipment including safety glasses, hard hat, gloves, protective shoes, hearing
protection, and any special equipment called for by the job conditions.
WARNING: Failure to observe standard safety practices could result in personal
injury. Service personnel and operators must be fully conversant with the
maintenance and operating procedures.
A. Place Multilift® on object to be lifted to determine grip.
1. Pads should have a minimum of ½’’ and maximum of 3’’ clearance with
object.

B. Place Multilift® on an object narrower than grip and with sufficient height to
provide clearance for leg assemblies for adjustment. DO NOT ATTEMPT TO
ADJUST LEG ASSEMBLIES WHILE Multilift® IS HANGING.
1. Care must be taken to ensure that the lifter remains stable and
balanced during adjustment.
C. Leg assemblies are attached to the core using ADJ. HANDLE in the following
manner:
1. Outer Leg Assembly is latched to OUTER CORES.
2. Inner Leg Assembly is latched to INNER CORE.
D. Leg assemblies are referenced to their respective core member by the spacing of the
TOOTH BLOCKS inside the leg assembly. The leg referenced to the INNER
CORE has (1) TOOTH BLOCK indexed to contact INNER CORE, the leg
referenced to the OUTER CORES has two (2) TOOTH BLOCKS indexed to
OUTER CORES.
E. Adjust legs for a level pick.
F. Ensure that the lifter’s components (leg assemblies, lift core, and lift assembly)
do not bind and have travel remaining after adjustment.
G. Multiple Leg Configurations:
1. Legs can be reversed for inside-out gripping.
2. Legs can be used in multiples for open ended boxes. *
3. Lift assembly can be positioned to either side of the leg assemblies to handle “L’’
shaped objects.*
4. Custom leg and pad configurations available (extended legs, hardened points, ball
joint, etc).*
5. Custom core lengths available.*
*Required additional hardware not included with standard unit.

Section VI. Operation.
Before attempting to use the Multilift® device ALWAYS perform
a test lift on the intended object(s) to confirm proper operation.
DO NOT use a Multilift® to handle objects beyond the rated
capacity or range.
DANGER
!
Manipulation of the Multilift® by ground personnel for the
purpose of alignment with load shall only be done with Multilift®
suspended above the wall. KEEP ALL HANDS AWAY FROM
MULTILIFT® DURING OPERATION.
DANGER
!
Surfaces of the load that come into contact with the gripping
surfaces must be free of any foreign material or coating that
could compromise the grip.
DANGER
!

A. Operation:
1. Ensure that the Multilift®’s capacity and range are appropriate to
the object being handled.
2. Ensure pads are clean and free of debris or contamination.
3. Position Multilift® at or near center of object to be lifted while
keeping the pads parallel to the gripping surfaces.
4. Lower Multilift® onto object, taking care to minimize impact.
5. Ensure pads do not grip surfaces more than eleven degrees in any
direction from vertical.
6. Ensure that all persons are clear of Multilift® and object.
7. Release tension on lift cable.
8. Raise Multilift® and load in a smooth motion; do not “jerk”.
9. Deposit at desired location.
10. Release tension on lift cable. (Note: avoid undue slamming of the
Multilift® into open position to prolong actuator life.)
11. Remove Multilift® (Multilift® is latched in open position
automatically).
12. Refer to Kenco.com for videos and tutorials on usage of the
Multilift®.
B. AVOID JARRING, WEINGING, AND OTHERWISE
UNNECESSARY MANIPULATION OF THE LOAD.
C. DO NOT ALLOW PADS TO GRIP SURFACES ANGLED MORE THAN
ELEVEN DEGREES IN ANY DIRECTION FROM VERTICAL.
DAMAGE TO THE LIFTER MAY RESULT.
D. AVOID HANDLING OF LOADS OFF CENTER.
E. DO NOT USE THE MULTILIFT® TO PICK MULTIPLES OF ITEMS
IN A SINGLE PICK.
F. OBSERVE ALL SAFETY PRACTICES ASSOCIATED WITH
OPERATION OF HOIST MACHINERY.
G. DO NOT USE MULTILIFT® TO DRAG LOADS.
H. DO NOT ALLOW LOAD TO CONTACT ANY SURFACE/OBJECT
WHILE BEING HANDLED.
Tip: The majority of wear on the Multilift® will result from shock loading, impacting,
and poor alignment of the Multilift® with the load. Minimizing these incidents will
greatly extend the life of the Multilift® and consumables.

The Multilift® wall handling device produces grip proportional
to and dependent on the weight of the load. It is for this reason
that while in operation the Multilift® and wall NEVER be
allowed to contact other items.
Section VII. Maintenance
A. Daily:
1. Visually inspect Multilift® for signs of stress and wear.
2. Check that bolts and nuts are snug.
3. Ensure free movement of all components.
4. Ensure that all warning labels are present and readable.
5. Check that actuator mounting screws are snug and seated.
6. Lubricate all moving mechanisms with penetrating OIL.
7. LUBRICATE ACTUATOR WITH LIGHT PENETRATING OIL ONLY
(WD40™)
8. For Pads:
a.Check that all pad mounting bolts and nuts are tight.
b.Verify freedom of rotation for pad angle.
c.Ensure that pad material is sound, and not de-laminated from backing plates.
d.Ensure that pad mounting bolts heads are min.3/32’’ below the surface of the pad.
(see ill.)
e.Ensure pads are clean and free of any foreign material or substance.
