Altec Industries, Inc. has developed a product improvement which relates to certain AT37G, AT237,

Refer to SIL 745 for items covered under the warranty policy. Altec will supply necessary parts to correct
this condition.
In order to determine if your unit is affected by SIL 745, compare the serial number of your unit with the list of
affected units as described on the SIL. The product improvement can be performed by the customer or you may
contact Altec at 1-877-GO-ALTEC (1-877-462-5832) for further assistance.
At any time, you may contact Altec at 1-877 GO ALTEC (1-877-462-5832) with your unit’s serial number to

Units Affected: Certain aerial devices built from November 2017 to September 2019
					
(see attached list)
Boom Rest Reinforcement
Altec is committed to providing our customers reliable products from initial delivery throughout
the useful life of the machine.
The affected units were manufactured with a clamp-style boom rest socket that is attached to
the subbase of the unit. Altec has discovered that cracks may develop in the bottom plate of the
boom rest socket.
Altec has designed reinforcement plates to be installed on the boom rest socket structure. These
are used to repair units which have developed cracks and to prevent cracks from occurring on
units which have not developed cracks. Clamp Boom Rest Reinforcement Kits are available
containing these parts for specific unit models. The kit part numbers are shown below. Altec requires that the appropriate kit be installed on each unit no later than the next regular maintenance
interval but no later than 90 days from the receipt of this SIL.
