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.
5. Attach the load to the boom.

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:
1. Written approval to use boom with your lift truck [29 CFR 1910.178(a)(4)]; 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 1910.178(a)(5)].
 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 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.
 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 1910.179(h).
 ONLY use rigging having maximum load ratings that exceed the load weight.
 DO NOT connect a load to only 1 hook, if the load is likely to rotate during lifting and/or transport operations. A load
should connect to both hooks simultaneously:
