Mounting Frame Inspection
Altec is committed to providing our customers with safe and reliable products from initial delivery
throughout the useful life of the unit.
Altec has discovered that the affected units may have square inside corners rather than rounded inside
corners on a mounting frame side plate. The square corners can cause excessive stress levels in the side
plate. Over time this could cause cracking of the side plate. Altec has redesigned the mounting frame side
plate to have rounded corners, and has developed an update process using a template to add a radius to the
corners on units in the field.
Altec requires the mounting frame to be inspected on each unit no later than the next preventive maintenance interval or 90 days from the receipt of this SIL, whichever comes first. Use the Inspection Procedure
beginning on page 2. If the inspection confirms the mounting frame side plate has square corners, call
1-877-GO ALTEC (1-877-462-5832) option 1 to order the Mounting Frame Update Template Kit, part
number 991344673. Use the kit to update the mounting frame upon receipt.
This inspection and repair are covered under the Altec Warranty Policy and can be performed by Altec, the
customer, or the customer’s warranty provider. Altec will perform the work for free at an Altec facility. If
the customer or the customer’s warranty provider performs the work, a warranty claim must be submitted
to be reimbursed for the cost of the parts and/or labor. Altec will allow up to $45 for the labor to perform
the inspection and up to $90 for the labor to perform the repair.
Call 1-877-GO ALTEC (1-877-462-5832) option 3 to schedule the work to be done by an Altec Mobile
Service technician or option 2 to schedule the work to be done at an Altec facility. Customers are responsible for the travel costs of an Altec Mobile Service technician if the technician performs the inspection
and/or repair at the owner’s location.
