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.

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.

Use Instructions:
Only trained, designated persons should use the fork attachment. “Designated person” means someone selected by his employer to use the device. Trainees under the direct supervision of a designated person also may use the S-Fork. Maintenance personnel also may use the S-Fork when necessary to perform employment duties.
Step 1 The user should perform an “Inspection[s] Before & During EVERY Lift” on p. 5, prior to connecting the attachment to the tine of a fork truck. Proceed to the next step ONLY IF the attachment passes the inspection
Step 2: Connect S-Fork to a fork truck tine. Slide the device over the end of a tine; then position the S-Fork at the desired point along the length of the fork tine
Step 4: Connect the load to the load hook. Position the S-Fork above the load and adjust the vertical position as necessary. Follow the lifting/hoisting procedures applied at your worksite to properly attach the load to the S-Fork hook.
otherwise reorienting when it is lifted from the ground. The swinging motion could result in serious injuries to the fork lift operator or other persons in the area.
Step 5 Tell every person in the area to clear the usage area including the travel path and then raise the forks sufficiently to elevate the load just a few inches. Verify that the connection is sound by leaving the load suspended for a moment. Proceed to the next step ONLY IF the connection is stable.
the ground and adjust the connection; then repeat step 5. If the connection still is not stable, return the load to the ground and select a different lifting device to lift and move the load.
Step 6 Slowly drive the forklift to the desired location and adjust the driving speed to minimize the degree of drum swing. Always follow the procedures applied at your worksite for safely hoisting material and operating a forklift
NOTE 1: The load will swing more significantly the greater the driving speed. Drive slowly to minimize movement
NOTE 2: The load will tend to swing opposite the direction of a turn and will swing out in front of the forklift during
Step 7 Only set the load on a flat, level surface to prevent unintended or uncontrolled movement as the load settles. Before lowering the load, make sure that it is not swinging or rotating. Slowly lower the forks until the load contacts the ground. Continue to lower the load to create slack between the shackle and load hook (of the S-Fork), and then disconnect the load from the hook. DO NOT disconnect the load from the hook until the load from rolling, falling over, or otherwise moving in an uncontrolled manner.

carriage of the fork truck WITHOUT slack and connect the snap hook (at the end of the strap) to the strap. Remove any slack in the strap by pulling it tight. Pull the strap from the end that connects to the cold shut (see FIG. 1 on p. 3). Verify that the S-Fork cannot slide off of the tine by tilting the fork truck mast forward. The S-Fork should be positioned on the tine as shown in Photo 1. NOTE: The S-Fork can still slide

Maintenance & Inspections:
A designated person must verify that the S-Fork complies with all regulations, codes, and standards that apply to hoisting devices in the location where it is used. A person designated to conduct inspections by your employer must do so before the S-Fork is used for the first time and prior to EACH
Inspections:
DO NOT use an S-Fork that is structurally damaged. Structural damage includes, but is not limited to,
bending, warping, cracking or other deformation of one or more of the following components: shackle; tension arm weldment; or fork tube weldment (see FIG. 1, p. 3). Restore the S-Fork to normal operating condition BEFORE using it again.
Inspections Before & During EVERY lift lift. In particular, the operator should:
1. Inspect for and remove all debris on load surfaces of the load hook, especially debris that might interfere with or prevent the S-Fork from adequately engaging the load; AND
2. Inspect the S-Fork to confirm that all parts are in normal operating condition.
Frequent Inspections
: maintenance personnel or other designated person(s) should visually inspect the S-Fork at least
once per month for:
1. Deformations, cracks, or excessive wear of any inspect the load hook, follow the recommendations of ASME B30.10-2005;
2. Loose or missing fasteners;
3. Excessive wear and tear to the safety strap or snap hook (at the free end of the strap).
Maintenance: the end-user must implement a maintenance program to ensure the proper function and safety of the S­Fork. A qualified person may, OF COURSE, establish a program used in preference to the maintenance procedures described below. However, if you apply the procedure that follows, complete EVERY step each performed.

The reader should understand the significant difference between Adjustments” or “Repairs,” and
“Modifications”.
An adjustment or repair refers to a simple correction that restores the S-Fork to normal operating condition, such as
tightening loose fasteners, or removing debris from the surface of the device. DO NOT use the S-Fork if adjustments and/or repairs are incomplete! Return the S-fork to service ONLY after finishing all necessary repairs and adjustments.
A modification is a change that alters the S-Fork from normal operating condition, like bending the structural
members. NEVER modify the S-Fork. Modifications may render the device unsafe to use.
: Perform a periodic inspection.
