Vestil manufactures 5 models of Lift Master booms. The 5 variants are distinguishable by boom length,
whether the boom length is adjustable or fixed, and maximum rated load. Each unit conforms to the generalized
specifications disclosed in this manual and fulfills our demanding standards for quality, safety and durability.
Vestil Manufacturing Corp. recognizes the critical importance of workplace safety. Each person who might
participate in the operation or maintenance of the product must read this manual. Read the entire manual and
fully understand the directions BEFORE using or performing maintenance on the boom. If you do not
understand an instruction, contact Vestil for clarification. Failure to adhere to 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 may result in property damage, serious
personal injury or death, and also are not the responsibility of Vestil.
This manual classifies personal injury risks and situations that could lead to property damage with SIGNAL
WORDS. These signal words announce an associated safety message. The reader must understand that the
signal word chosen indicates the seriousness of the described hazard.

Safety Recommendations:
Vestil diligently strives to identify foreseeable hazards associated with the use of its products. However,
material handling is inherently dangerous and no manual can address every conceivable risk. The end-user
ultimately is responsible for exercising sound judgment at all times.
SERIOUS INJURY. Use of this signal word is limited to the most extreme situations.
SERIOUS INJURY.
MODERATE injury.
damage the boom.
Electrocution might result if the boom contacts electrified wires. Reduce the likelihood that an
operator or bystander might be electrocuted by applying common sense:
DO NOT contact electrified wires with the boom;
DO NOT use the boom in an area where it will contact electrified wires;
DO NOT operate the boom close to electrified wires or other sources of electricity;
Before using the boom, always inspect the usage area for unusual conditions that require special precautions.
Material handling is dangerous. Improper or careless operation might result in serious personal
injuries sustained by the boom operator(s) and bystanders. Always conform to OSHA material handling
regulations (29 CFR section 1910 Subpart N). Subpart N includes 2 sections that regulate the use of forkmounted boom-type devices: section 1910.178, “Powered industrial trucks,” and section 1910.179, “Overhead
and gantry cranes” (see http://www.osha.gov/). In addition to regulatory requirements, boom operators should
conform to the following:
DO NOT use a damaged boom. Inspect the boom before each use according to the inspection instructions on
p. 22-23. DO NOT use the boom unless it passes every part of the inspection.
DO NOT use the boom if the safety chain/strap is damaged or absent. The only purpose of the safety chain is
to prevent the boom from sliding off of the forks—it is NOT intended or designed to bear the full load rating.
DO NOT use a malfunctioning or structurally compromised boom.
DO NOT lift the boom until it is securely connected to the carriage of the fork truck with the restraint strap.
DO NOT attempt to lift a load weighing more than the boom’s maximum rated load (see Table, p. 2).
DO NOT stand beneath or travel under the boom at any time, and especially not when a load is suspended.
DO NOT permit any person to stand beneath or travel under the boom or the load.
Inform all persons in the area that you are going to use the boom; instruct them to stay clear of the device and
the supported load during operation.
Failure to read and understand the instructions included in this manual before using or servicing the boom
constitutes misuse
DO NOT allow people to ride on either the boom or the load.
DO NOT use the boom if any product label (see p. 24) is unreadable, damaged, or absent. Contact Vestil to
order a replacement label(s).
(continued from p. 3)
ALWAYS apply proper (fork) lift operation practices learned during your training program. Before raising the
boom from the floor AND before attaching the load to the boom, tilt the fork lift mast away from the boom to
ensure that the boom will not slide towards the tips of the forks.
ALWAYS load the boom according to the instructions that appear on p. 20-21. Failure to properly position a
load might cause the load to swing, which might result in the operator(s) or other persons sustaining serious
personal injuries.

Review “Safety Guidelines” on p. 2-3 before using the boom.
1. Insert fork truck tines into the fork pockets and drive as far forward as possible; then lower the forks completely.
The drawings below demonstrate this step:
Safety chain/strap
wrapped around fork
carriage & snap hook
fastened to cold shut
2. Securely connect the boom to the carriage of the fork truck with the safety chain.
Wrap the safety chain (or strap) around the fork carriage so that it cannot slide free of the carriage; then fasten
the hook to the chain/strap. There should be no slack in the chain/strap. The only purpose of the safety chain is to
prevent the boom from sliding off of the forks—it is NOT intended or designed to bear the full load rating.
3. [Telescoping models only] Adjust the boom length:
a. Loosen the X-handle locking bolt (“locking bolt”), by turning it counterclockwise.
b. Grasp the adjustment handle at the end of the boom and pull the boom to the desired length.
c. Tighten the locking bolt by turning it clockwise. Turn the locking bolt until it cannot be tightened more.
4. [LM-OBT-4k, 6k & 8k Models] Adjust the pitch of the boom as required by the size/shape of the
intended load. To safely perform the adjustment process requires at least 2 people:
4. [OBT models] Adjust the boom angle:
a. 1 person must grasp the red pitch handle with one hand
b. while the other person pulls out the locking pin; then
c. both persons press down on the angle-adjusting handle until the desired angle is achieved;
d. The person who removed the locking pin should reinsert the pin through the openings in the
adjustment brackets and through the locking pin channel.
Verify that the load weighs less than the maximum rated load of your boom model AND that your fork lift is rated to

laterally-centered load. [29 CFR 1910.178(a)(5)].
presented in the tables that appear with Figures 1B, 1D, 2B, 2D, 3B, 3D, 4B & 4D is the maximum rated load of the
specified BOOM ONLY; you MUST compare the appropriate table entry with the adjusted maximum rated load label
provided by the fork truck manufacturer.
(continued from p. 19)
Test the stability of the load attachment. Raise the forks slowly to minimize load movement. Raise the forks until the
load is entirely suspended from the boom. Watch the load and boom closely for either of the following issues:
1. Load sliding in rigging; or
2. Boom sliding towards tips of forks.
If you notice either #1 or #2 occurring, immediately lower the forks until the load is completely supported by the
ground; then adjust the rigging. Retest the stability of the load in the rigging. If a stable lift cannot be performed, DO
NOT use the boom.
While transporting a load with the boom, the load should only be 6-8 inches from the ground, but adjusted to avoid
obstacles along the travel path.
DO NOT exceed approximately 1.5mi./hr (2.4km/hr) while transporting a load with the boom, and travel ONLY on
smooth, level surfaces. Execute turns slowly and smoothly.
a. Connect the load to appropriate rigging;
b. Attach the rigging to the end hook or to both the end hook and the stabilizing hook;
End hook

hook
c. Verify that the load attachment is stable (see “Test the stability of the load attachment” in the warning
messages above);
d. Raise the load until it is elevated no more than 6-8 inches above the ground (entirely suspended from
the boom).
e. Slowly transport the load to the desired unloading location;
f. Slowly lower the load until it is entirely supported by the ground, and there is slack in all rigging.
g. Disconnect the rigging from the hooks;
h. Lower the forks until they are no more than 6-8 inches above the ground;
i. Transport the boom to its storage location.
NOTE: Users of OBT and OBNT model booms should return the boom to the fully
lowered (horizontal) position by reversing Step 4 on p. 23 BEFORE backing out of
the fork pockets.
Inspection and maintenance personnel should immobilize the boom before either conducting
inspections or performing maintenance. The boom is properly immobilized if it cannot tip over.
If one or more problem is discovered during an inspection, restore the boom to normal operating
condition BEFORE using it again. DO NOT use a boom that is structurally damaged in any way. Structural
damage includes, but is not limited to, cracked welds, warping or deformation of the fork pockets, support leg,
frame members, boom, boom sleeve, hooks or shackles.
Lift Master booms function like a hoist-less crane: instead of using a hoist to lift loads, the bridge girder rises
and lowers through the movement of the forks of a lift truck. Therefore, boom owners/end-users should inspect
the boom regularly following an established process. An example of an inspection procedure appears in 29 CFR
1910.179 (visit http://www.osha.gov/ and navigate to “Regulations” section 1910.179). Paraphrased, relevant
portions appear below:
1. Initial inspection — before a new or modified crane (boom) may be used for the first time, it must be inspected
to insure normal condition.
After the first use, the boom end-user/owner must conduct the following 2 types of inspection:
The following items shall be inspected for defects at the intervals specifically indicated, including observation
during operation for any defects which might appear between inspections. All deficiencies such as those listed
shall be carefully examined to determine whether they constitute a safety hazard:
[Inspect daily] All functional operating mechanisms (boom, X-handle locking bolt, boom sleeve, base
frame weldment, safety chain/strap, fork pockets, support arm, and all fasteners) for maladjustment or
damage that might interfere with proper operation. Inspect the boom for:

(base frame weldment), safety chain/strap, fork pockets, support arm, and all fasteners) for excessive
wear.
3. Periodic inspection [29 CFR 1910.179(j)(1)(ii)(b)] — 1-to-12 month intervals.
Complete inspections of the crane (boom) shall be performed at intervals depending upon its activity, severity
of service, and environment, or as specifically indicated below. Perform all of the applicable “Frequent
inspection” steps and carefully examine the boom for any the problems that appear below () to determine
whether they constitute a safety hazard:
Deformed, cracked, or corroded members.
Loose bolts or rivets.
Worn, cracked or distorted parts such as pins, shackles, hooks.
Boom not in regular use:
For each of the 3 bullet points below, in addition to the inspections, any boom, which has been idle for a period of
a month or more due to shutdown or storage of the boom, must be given a thorough inspection before it is used
again. An appointed person, whose approval is required before the boom may be used, must inspect the boom for
all types of deterioration. A certification record must be available for inspection. The record must include at least
the date of inspection, the signature of the person who performed the inspection and an identifier for the rope
inspected.
A boom which has been idle for a period of 1 month (or longer), but less than 6 months, shall be
given a “Frequent inspection” before returning it to service.
A boom which has been idle for longer than 6 months shall be given a “Periodic [complete]
inspection” before placing it in service.
Standby booms shall be given a frequent inspection at least semi-annually (twice per year; 1
inspection each 6 months).
Annual performance evaluation: At least once per year, authorized inspection personnel should verify the
soundness of the boom. Use the LM to lift a maximum rated load. Afterwards, conduct a “Frequent inspection” to
verify that the product is in normal operating condition.
Maintenance:
The end-user, i.e. operators and operators’ employer, must implement a maintenance program to ensure that the
product functions properly and is adequately maintained. OSHA “General Industry” standards applied to
“Overhead and gantry cranes,” 29CFR 1910.179, describe official, recommended maintenance procedures. The
following steps should be utilized in conjunction with those recommendations.
The end-user is responsible for selecting and training employees to work on the boom. “Work on”
refers to operating, loading, cleaning, servicing, maintaining, or repairing the product. ONLY trained, authorized
maintenance personnel or contractors should perform inspection, maintenance, or repair work.
Step 1: Tag the boom, “Out of Service.”
Step 2: Remove any dirt or other matter from all surfaces.
Step 3: Conduct a “Before each use” inspection. If deformity, corrosion, rusting, or excessive wear of structural
members is found, DO NOT use the product.
Step 4: Perform all other necessary adjustments, replacements and/or repairs. DO NOT modify the boom.
The reader should understand the significant difference between necessary adjustments and
repairs, and modifications.
An “adjustment” is a simple correction that restores the boom to normal operating condition, such as tightening
loose fasteners, or removing dirt or other debris from the surface. “Repair” refers to removing worn parts and
installing replacement parts.
DO NOT use the Lift-Master boom if adjustments and/or repairs are incomplete! Return it to service ONLY
after finishing all necessary repairs and adjustments.
A “modification” is a change that alters the boom from normal operating condition, like bending the structural
members or removing a part or several parts. NEVER modify the boom without the express, written approval of
Vestil. Modifications may render the device unsafe to use.
Step 5: Make a dated record of any repairs, adjustments and/or replacements.
