SIGNAL WORDS

This manual classifies personal injury risks and situations that might cause property damage with “Signal

words”. Signal words indicate the seriousness of injuries that might result if a particular act or omission occurs.

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

Safe Use Recommendations:

Vestil strives to identify all foreseeable hazards associated with the use of its products. However, material handling is dangerous and no manual can address every possible risk. The most effective means for avoiding injury is for the end user to apply sound judgment whenever using this device.

Material handling is dangerous. Improper or careless operation might result in serious personal injuries. Acquire a copy of the latest version of ANSI B56.1, which is freely downloadable on www.ITSDF.org. Apply all relevant portions of Part II “For the User”. The following recommendations are intended to complement the guidance provided in B56.1.

 Always use this boom in compliance with all rules applied to fork truck attachment at your worksite.  Failure to read and understand the instructions included in this manual before using or servicing the boom

constitutes misuse.  DO NOT use a damaged boom. Inspect the boom before each use according to the relevant inspection instructions

that appear on p. 25-26 to determine whether the boom is in normal operating condition.

 DO NOT contact electrified wires with the boom.  DO NOT use the boom if the safety chain is damaged or missing. 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 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. Load ratings for all boom

variants appear on pages 4, 6, 8, 10, 12, 14, 16, 18, 20, and 22.

 NEVER lift this boom over people.  DO NOT permit any person to stand beneath or travel under the boom or the load.  Inform everyone in the area that you are going to use the boom. Instruct them to stay clear of the boom and the

supported load during use.

 DO NOT allow people to ride on either the boom or the load.  DO NOT use the boom if any product label (see p. 27) is unreadable, damaged, or missing. Contact Vestil to order

a replacement label(s).

 ALWAYS apply proper (fork) lift operation practices learned during your training program.  Always make sure that shackle pins (see shackles in exploded parts diagrams, pp. 3-22) are secure before applying

a load to the load hook. Tighten the screw pin before each use.

 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 follow the loading and use instructions that appear on p. 23-25. Failure to properly position a load might

cause a dangerous degree of load swing when the boom is elevated.

 Only use the boom to lift loads. DO NOT use the boom to drag items.  Transport loads with the bottom of the load and the forks as low as possible.  Drive suspended loads at low speed. Brake and turn slowly cautiously.  DO NOT modify the boom in any way. Modifications automatically void the limited warranty (see p. 28) and might

make the boom unsafe to use.

SERIOUS INJURY. Use of this signal word is limited to the most extreme situations.

SERIOUS INJURY.

MODERATE injury.

The center of gravity of the boom changes as boom length changes. As shown in the diagram below, the

horizontal center of gravity may be located at any point from RHCG to EHCG:

 Retracted horizontal center of gravity (RHCG): boom fully retracted and unloaded. RHCG is measured from

the “origin point” of the above diagram (edges of the fork pockets);

 Extended horizontal center of gravity (EHCG): boom fully extended and unloaded. EHCG is also measured

from the “origin point” of the above diagram (edges of the fork pockets);

 All other combinations of boom extension and load position produce a horizontal center of gravity located

somewhere between RHCG and EHCG.

The center of gravity of the boom changes as boom length changes. As shown in the diagram below, the horizontal

center of gravity may be located at any point from RHCG to EHCG:

 Retracted horizontal center of gravity (RHCG): boom fully retracted and unloaded. RHCG is measured from the

“origin point” of the above diagram (edges of the fork pockets);

 Extended horizontal center of gravity (EHCG): boom fully extended and unloaded. EHCG is also measured from

the “origin point” of the above diagram (edges of the fork pockets);

 All other combinations of boom extension and load position produce a horizontal center of gravity located

somewhere between RHCG and EHCG.
