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. SAFETY PRINCIPLES Page 2 of 27 Copyright 20 Vestil Manufacturing Corp.

3 LM-series fork-mountable booms 0/ Vestil manufactures models of Lift Master booms. The 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: ) 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 SERIOUS INJURY. Use of this signal word is limited to the most extreme situations. Identifies a hazardous situation which, if not avoided, COULD result in DEATH or SERIOUS INJURY. Indicates a hazardous situation which, if not avoided, COULD result in MINOR or MODERATE injury. Identifies practices likely to result in product/property damage, such as operation that might damage the boom. SAFETY RECOMMENDATIONS: Failure to read and understand the instructions included in this manual before using or servicing the boom constitutes misuse. Study the entire manual before you use the product for the first time and before each subsequent use. Read the manual to refresh your understanding of the safe operation, inspection and maintenance procedures explained on p If questions remain after you finish reading the manual, contact Vestil for answers. DO NOT attempt to resolve any problems with the boom unless you are authorized to do so and are certain that it will be safe to use afterwards. 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. Your use of the boom must always conform to OSHA material handling regulations (29 CFR section 90 Subpart N). Subpart N includes 2 sections that regulate the use of forkmounted boom-type devices: section 90.78, Powered industrial trucks, and section 90.79, Overhead and gantry cranes (see 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 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. 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 (continued from p. ) DO NOT allow people to ride on either the boom or the load.

4 LM-series fork-mountable booms 0/ DO NOT use the boom if any product label (see p. 2) is unreadable, damaged, or absent. Contact Vestil to order a replacement label(s). 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 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.

Material handling is inherently dangerous; improper use of this product might result in serious personal injuries. To reduce risk: Verify that the load weighs less than the maximum rated load of your boom model AND that your fork lift is rated to safely lift both the boom and the load. Agency rule (not law) compels you to contact the manufacturer of your fork lift truck BEFORE using a boom to request:. Written approval to use boom with your lift truck [29 CFR 90.78(a)()]; AND 2. Markings (labels) for the lift truck that: Identify your LM-boom; AND Provide the approximate net weight of the forklift truck and boom at the maximum fork elevation with laterally-centered load. [29 CFR 90.78(a)()]. DO NOT use the boom UNTIL the lift truck manufacturer provides adjusted maximum rated load tags for your fork lift. DO NOT attempt to lift more than the rated load of the boom or lift truck, whichever is smaller. The information presented in the tables that appear with Figures B, D, 2B, 2D, B, D, B & D 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. Strictly adhere to safe load-lifting rules applied at your worksite. Attach the load to the boom following OSHA-recommended practices for Hoisting equipment, 29 CFR 90.79(h). ONLY use rigging having maximum load ratings that exceed the load weight. DO NOT connect a load to only hook, if the load is likely to rotate during lifting and/or transport operations. A load should connect to both hooks simultaneously: Attaching load to both hooks limits load rotation Single-hook (circled) load likely to rotate (continued Load from p. 9) Load Page 2 of 27 Copyright 20 Vestil Manufacturing Corp.

24 LM-series fork-mountable booms 0/ 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:. Load sliding in rigging; or 2. Boom sliding towards tips of forks. If you notice either # 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 -8 inches from the ground, but adjusted to avoid obstacles along the travel path. DO NOT exceed approximately.mi./hr (2.km/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 Stabilizing 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 -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 -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 on p. 2 BEFORE backing out of the fork pockets.

25 LM-series fork-mountable booms 0/ Inspections & Maintenance: 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 (visit and navigate to Regulations section 90.79). Paraphrased, relevant portions appear below:. 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: 2. Frequent inspection [29 CFR 90.79(j)()(ii)(a)] Daily to monthly intervals. 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:. Dirt or other matter on the surface of the boom. 2. Pivot point wear (if applicable);. Looseness or wear of any parts that move during boom operation;. Integrity of hardware and fasteners, including but not limited to bolts, nuts, pins, knobs, shackles, and hooks;. Normal operability of manually (by hand or foot) operated mechanisms;. Abnormal or noisy movement during use; 7. Excessive wear of, damage to, or indications of metal fatigue in any portion of the fork pockets, support frame, boom or boom sleeve; 8. Damaged or unreadable labels; 9. Thinned regions or tears in the safety strap, or stretching, thinning, or twisting of any link(s) in the safety chain; 0. Evidence of corrosion or rust-related metal erosion. [Inspect daily (visually) and at least once per month inspect and make a certification record, which includes the date of inspection, the signature of the person who performed the inspection and the serial number (or other identifier) of the hook inspected] Hooks with deformation or cracks. Immediately discard cracked hooks or hooks whose throat opening is more than percent wider than the normal throat opening, or that are twisted more than 0 from the plane of the unbent hook. [Inspect daily (visually and at least once per month inspect and make a certification record which includes the date of inspection, the signature of the person who performed the inspection and an identifier of the chain which was inspected] Hooks and shackles, including end connections, for excessive wear, twist, stretch. Disconnect any hook or shackle found to exhibit these problems and discard them. [Inspect weekly] 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 excessive wear.. Periodic inspection [29 CFR 90.79(j)()(ii)(b)] -to-2 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.

26 LM-series fork-mountable booms 0/ Loose bolts or rivets. Worn, cracked or distorted parts such as pins, shackles, hooks. Boom not in regular use: For each of the 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 month (or longer), but less than months, shall be given a Frequent inspection before returning it to service. A boom which has been idle for longer than 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; inspection each 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 90.79, 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 : Tag the boom, Out of Service. Step 2: Remove any dirt or other matter from all surfaces. Step : Conduct a Before each use inspection. If deformity, corrosion, rusting, or excessive wear of structural members is found, DO NOT use the product. Step : 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 : Make a dated record of any repairs, adjustments and/or replacements.
