PRODUCT INTRODUCTION:
Thank you for purchasing a fork-mounted Lift Master boom (“boom”, “product” or simply “LM”) made by Vestil
Manufacturing Corporation (“Vestil”). Our booms are durable, high-quality products that combine safetyconscious design features and rigorous engineering. Although operation and use procedures are relatively
intuitive, all persons who might use or operate of this product must familiarize themselves with the instructions
provided in this manual
Standard design features include: 2 fork pockets that receive the tines (forks) of a fork truck; 2 load attachment
points (hooks); and either a safety chain or safety strap to wrap around the fork carriage and prevent the boom
from sliding off of the forks during use. Dimensions of offered models, as well as other product specifications
appear in the following table:

Vestil Manufacturing Corp. created this manual to acquaint owners and operators of our fork-mounted booms
with safe operation and maintenance procedures. Employers are responsible for instructing employees to
use the product properly. Employees and any other person, who might foreseeably assemble, use,
repair, or perform maintenance on the boom must read and understand every instruction BEFOREHAND.
Boom operators should have access to the manual at all times and should review the directions before each
use. Contact Vestil for answers to any question you have after reading the entire manual.
Although Vestil diligently strives to identify foreseeable, hazardous situations, this manual cannot address
every conceivable danger. The end-user is ultimately responsible for exercising sound judgment at all times.

LM-series fork-mountable booms 01/11 rev. 11/14/2013
SAFETY PRINCIPLES:
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.
Identifies a hazardous situation which, if not avoided, WILL result in DEATH or
Identifies a hazardous situation which, if not avoided, COULD result in DEATH or
Indicates a hazardous situation which, if not avoided, COULD result in MINOR or
Identifies practices likely to result in product/property damage, such as operation that might
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.

p
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.

All Lift-Master booms share the features identified in the diagram below.

The center of gravity has a vertical component as well as a horizontal component. The vertical center of gravity is
located 15.5 in. (~39.4cm) above the bottom edges of the fork pockets. The horizontal component ranges from 31
inches to 47 inches measured from the outer edges of the fork pockets. As shown in the diagram above:
Retracted horizontal center of gravity (RHCG): boom fully retracted with a load attached at position A, the
center of gravity is located 31 inches (~79 cm) from the outer edges of the fork pockets;
Extended horizontal center of gravity (EHCG): fully extended with a load attached at position J, the center of
gravity is located 47 inches (~119 cm) from the outer edges of the fork pockets.
All other combinations (of boom extension and load position) yield horizontal centers of gravity located at or
between RHCG and EHCG.
