Safety Guidelines:

Failure to read and understand the instructions included in this manual before using or servicing this fork attachment
constitutes misuse of the product. Product misuse automatically voids the “Limited warranty”

Study the entire manual before you use the product for the fi

rst time and before each subsequent use as necessary to
refresh your understanding of the use, inspection and maintenance procedures explained on p. 4 & 5. Each person, who
will or might use or maintain the attachment, should read the entire manual and fully understand the directions BEFORE
using or performing maintenance on the device. If you do not understand an instruction, ask your employer/supervisor for
clarification, because failure to apply the directions in this manual might lead to serious personal injury or even death

Vestil is not liable for any injury or property damage that occurs as a consequence of failing to apply either: 1) the
instructions that appear in this manual; or 2) the information disclosed on labels affixed to the product. Furthermore,
failure to exercise good judgment and common sense while using or maintaining the product could result in property
damage, serious personal injury or death.

Electrocution hazard: DO NOT contact electrified wires with any part of the fork attachment (S-Fork), the

fork lift, or the attached load. Always inspect the area where the device will be used prior to use.

Improper use might result in serious personal injuries. Therefore, EVERY PERSON who might use,
perform maintenance on, or service the fork attachment must understand and apply all of the following recommendation s :
 DO NOT attempt to resolve any problem with the fork attachment unless: 1) you are authorized to do so; AND 2) you

are certain that it will be safe to use afterwards.

 Inspect the attachment before each use if necessary to recall “Use instructions” (p. 4).
 DO NOT use the device unless it is in satisfactory condition! If you observe any significant damage to, for instance, the

fork tube weldment, tension arm, hook or shackle (see FIG. 1 on p. 3), immediately tag the unit “Out of Service” and
inform authorized maintenance personnel about your observations. DO NOT use the attachment until it is restored to
normal condition.

 This device is designed for material handling only. DO NOT use the attachment in conjunction with personn el-conveying

equipment, such as work platforms.

 DO NOT leave an elevated load unattended. Lower the forks until the load is fully supported by the ground, and

disengage the load from the hoist hook before leaving it unattended.

 DO NOT alter the device from its original configuration. Unauthorized modifications might make the fork attachment

unsafe to use. If injuries and/or property damage occurs AFTER modifying (altering from original form) the
product without authorization from Vestil, fault belongs exclusively to the person who modified the product.

 DO NOT use the fork attachment to lift and move a load that cannot be adequately stabilized when lifted with the S-

Fork. ALWAYS apply the relevant lifting practices implemented at your worksite.

 DO NOT sit on or apply any weight/pressure to a suspended load.

(see p. 7).

 DO NOT attempt to lift a load that weighs more than the rated load of the attachment OR the lift truck, whichever is

smaller. ALWAYS make sure that the net weight applied to the fork attachment does not exceed the rated load of the

attachment OR the lift truck, whichever is smaller.

 DO NOT lift a load higher than necessary. (See “Use Instructions” on p. 4).
 DO NOT raise a load above a person(s) or allow anyone to stand or reach beneath a suspended load.
 NEVER use the device to lift a load over people or to lift any apparatus that supports people, such as a work platform.

To maximize the service life of the fork attachment:

 Use only replacement parts supplied or approved by the manufacturer.
 ALWAYS store the S-Fork in a dry location that shelters it from the elements to prevent damage that might occur if

contact with water or other liquids occurs.

 Maintain the product as suggested in “Maintenance & Inspections” on p. 5.
