DEATH or INJURY can occur from improper use or care.
1. Sling users shall be trained Do not use this sling unless you are properly trained.
See page 6 for training.
2. Read and follow all instructions and warnings in this manual.
3. Check tag to conrm that sling is adequately rated for the load. See page 7 for chart.
4. Inspect sling for damage including:
• Missing or unreadable Identication Tag
• Ensure Check-Fast® External Warning Indicator or tell-tail indicators extend past
the tag area of each sling
• If ber optics are installed, ensure light transmits from end to end
• Holes, tears, cuts, abrasive wear or snags
• Ensure inner red cover is not visible
• Acid or caustic burns
• Exposed core yarn
• Broken or damaged core yarn
• Weld splatter or heat damage
• Fittings that are pitted, corroded, cracked, bent, twisted, gouged or broken
• Any other condition, including visible damage, that causes doubt as to the
continued use of the sling
Inspection Frequencies
1. All slings and rigging shall be inspected before each use.
2. Documented periodic inspections shall be completed at least annually or more frequently
depending on service.
• Refer to ASME B30.9 and / or contact manufacturer for recommendations for
guidance on service intervals.
IF ANY OF THESE ARE DETECTED - SLING SHALL BE REMOVED FROM SERVICE IMMEDIATELY

1. Determine the weight and center of gravity of the load. For special lifts consult
manufacturer for additional support and/or suggested products.
2. Check the sling tag to conrm that the sling is rated adequately for the load in the
manner or hitches that it will be used. Refer to load angle, choke angle and other relevant
charts.

LOAD ANGLE CHART
Angle factor must be applied to calculate the reduced sling
capacity when lifting force is not at 90˚ to the plane of the load!
Multiply angle factor x sling’s vertical rated load to
calculate the reduced capacity at the angle.

PERCENTAGE OF SLING RATED
CAPACITY IN A CHOKER HITCH
Use caution with lifts at angles less than 45˚and do not make lifts with slings at less than 30˚. When
possible, use longer slings to minimize angular tension by increasing the angle. Severe angles can
greatly reduce sling strength.

3. Check chemical resistance. Twin-Path® slings are generally resistant to common chemicals.
Resistances in this chart are based on common concentrations at room temperature. Elevated
concentrations and temperatures may aect chemical resistance. Contact Slingmax for more
information when using in environments with elevated concentrations of chemicals and/or
temperatures.

Hydraulic Fluid Excellent Chlorine bleach Poor
Crude Oil Excellent Sodium Hydroxide Fair

Some chemicals on this chart (including those rated as“Excellent”) can damage the sling
cover. Contact Slingmax® for more information.

USE (Continued)
To avoid injury, it may be necessary to use multiple persons or an overhead
lifting device to lift the slings and rigging.
7. Protect sling from abrasive surfaces, pinch hazards, and edges. Use abrasion
protection for abrasive surfaces and cut protection for edges on the
hardware or load.
See page 5 for Cut and Abrasion Protection.
8. Ensure sling paths are smooth in the hitch without any twisting or bunching.
Sling shall not be twisted, tied into knots, or joined by knotting.

4. Be sure warning indication devices are operable.
Do not drag sling over any surface.
Do not expose to damaging chemicals and/or temperatures over 180˚F/82˚C.
Refer to manufacturer for additional information.
5. Select compatible ttings.
6. Center the sling and the load on the hardware being used. Avoid bunching the
sling. Do not fold sling, rather, push together.

USE (Continued)
9. Equalize the slack by hand. Do not equalize the sling by using the crane or hoist to
create tension.
Keep hands clear when the sling is being tightened.
10. Carefully lift the load.
Balance, maintain control and avoid sudden movement or jerking of the load.
Be alert for snagging of the load.
STAND CLEAR OF LOAD AT ALL TIMES.
DO NOT RIDE ON SLING OR LOAD.
STOP THE LIFT IMMEDIATELY if the load does not lift evenly, the external warning
indication devices react, or any other observed failure of the rigging is detected.
DISPOSAL
Before disposing of Twin-Path® slings, the slings shall be cut in half to prevent
inadvertent use.
Waste must be disposed of in accordance with national and local
environmental regulations.
CARE
Store slings to prevent contact with possible mechanical damage, corrosion, dust, grit
and extreme temperatures.
To clean: use mild soap and water and allow to air dry before storing.
Do not machine wash or dry, to avoid damaging the sling.
REPAIR
Field repair is not permitted. Return sling to a Slingmax® Dealer for repairs. Visit
www.slingmax.com for list of authorized Slingmax® Dealers.
Attempting to repair sling can result in sling failure, load drop, and death or serious
injury.

The CornerMax®Pad creates a “tunnel” of cut
protection which is known as the No Touch Zone.
The corner of the load does not come in contact
with the pad or the sling. The CornerMax®Pad is
specically designed to be used in 90˚angle
applications. Rated for 25,000 lbs per inch of sling
width.
CornerMax® Sleeve is made from tough high
performance ber that is specically woven to
provide cut protection for a variety of edges and
surfaces. CornerMax®Sleeves can be used in
many dierent angles and applications. Rated for
25,000 lbs per inch of sling width.
Synthetic Armor Pads protect slings from
abrasion damage that can be caused by contact
with rough surfaces such as concrete beams and
structures. They are also used to protect nished
or painted loads from marring. Synthetic Armor
can be made to t any length or width sling.
The pin area of a shackle can damage synthetic
slings. Placing synthetic slings on the pin should
be avoided. Shackles may have a sharp edge
where the pin goes through the shackle ear. If the
sling is rigged on this area, it could become
severely damaged. If you must rig on the pin,
protect your sling with a Shackle Pin Pad.
CUT AND ABRASION PROTECTION
Slings in contact with edges, corners, protrusions, abrasive surfaces or connecting hardware
shall be protected with a material of sucient strength, thickness and construction to prevent
damage. Cut protection shall be rated and labeled for its intended use.
Failure to use proper protection can result in sling failure, load drop, and death or serious
injury.
Available Abrasion Protection
Additional cut & abrasion protection information available from the manufacturer.
