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” (see p. 7).
Study the entire manual before you use the product for the first 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 recommendations:
 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 personnel-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.
