the weight of the truck and boom combination, and show the capacity of the truck with the boom at
maximum elevation with the load laterally centered. Use the LOAD TEST RECORD
page at the end of this
manual to record the weight used to load test your boom based on the rerated capacity.
INSPECTIONS
Inspections and repairs should only be performed by qualified persons. Compare the results of each
inspection to the RECORD OF SATISFACTORY CONDITION
(the “RECORD”). Do not use the boom unless all parts
are in satisfactory condition. Replace parts that are not in satisfactory condition before using the boom again.
DON’T GUESS! If you have any questions about the condition of your boom, contact the
TECHNICAL SERVICE
department. The phone number is provided on the cover page of this manual. Never make temporary repairs
of damaged or missing parts. Only use manufacturer-approved replacement parts. Replace the entire unit if it
cannot be restored to satisfactory condition.
WARNING
Immobilize the boom before conducting inspections and performing maintenance. If an inspection reveals
problems, restore the boom to satisfactory 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, or boom sleeve.
1. Before each use — Visually examine the boom for cracks, severe rusting/corrosion, damaged hooks and/or
shackles, and damaged support leg.
2. Monthly inspection — At least once per month, and before using the boom for the first time, inspect the
following components for conditions that might interfere with normal operation.
Frame and fork pockets — Fork pockets should be square and solid. Each pocket should be rigidly welded to
the frame. Look for significant wear, damage, or indications of metal fatigue to any portion of the fork
pockets, support frame, boom, or boom sleeve.
Boom — Check all welds. The boom should be straight and undamaged, i.e. no cracks, punctures, warps, etc.
Telescoping models should slide without binding inside the receiver/sleeve.
Safety chain — All links of the chain should be intact and of equal dimensions. Chains should be securely
attached to the frame by means of a lap link. The snap hook at the end of the chain should close completely
and automatically.
Hooks and shackles — Examine the end hook & the stabilizing hook. Record a measurement of the throat
opening of each hook. Compare the measurements with those taken during the very first inspection. Replace
a hook if its throat opening is more than 15 percent wider than the original throat opening measurement, or if
the hook is twisted more than 10° from the plane of the unbent hook. Discard damaged hooks. The latch of
the end hook should close automatically. Shackles should be securely attached to the underside of the boom.
Examine all pins that attach shackles to the boom for cracks and warps.
Locking bolt (telescoping models) — Confirm the locking bolt can solidly engage the top of the boom.
Support leg — Inspect the support leg. It should be straight, undamaged (no cracks or deformations), and
securely attached to the underside of the boom.
Labeling — The product should always be labeled as shown in the LABELING DIAGRAM on p. 23. Replace any
label that is damaged, significantly faded, or not easily readable from a reasonable distance.
3. Annual Lift Test – At least once per year, perform a LOAD TEST (p. 21) of the boom. Afterwards, conduct a
MONTHLY INSPECTION. Confirm SATISFACTORY CONDITION before returning it to service.
MAINTENANCE
Implement a maintenance program to ensure that the boom remains in normal operating condition. The
following steps should be utilized in conjunction with maintenance procedures applicable to fork truck
attachments provided in the most recent edition of ANSI B56.1.
Step 1: Tag the boom, “Out of Service.”
Step 2: Remove dirt and other matter from all surfaces.
Step 3: Conduct a Monthly inspection. If severe deformities, corrosion, rusting, or excessive wear of structural
members is found, DO NOT use the product.
Step 4: Perform all necessary adjustments, replacements and/or repairs but DO NOT modify the boom.
WARNING
DO NOT return the boom to service until all necessary adjustments and repairs are complete! An adjustment is a
simple correction that restores the boom to SATISFACTORY CONDITION, such as tightening loose fasteners or
removing debris from surfaces. Repair means removal of worn parts and installation of replacement parts. NEVER
modify (alter) the boom, e.g. bend a structural member or remove a part or parts.
Step 5: Make a dated record of all repairs, adjustments, and replacements performed.
