Technical Service Bulletin SIL 850 — 2020 ALTEC SERVICE BODY

The body compartment wiring on certain Altec aerial devices, digger derricks, and body-only units built from 2014 to 2021 contains an in-line fuse located close to the lighting in the compartment, while other units are fused upstream, closer to the power source. Altec has learned that the units affected should have an in-line fuse close to the lighting, but this fuse was not installed on some units. In addition, some units may have exposed terminals at the end of certain portions of the wiring in the body. If the exposed terminals contact each other or with ground, the resulting direct short could damage the body compartment lighting. Inspect the body compartment lighting circuit at the unit's next scheduled service interval or within six months of receiving the SIL, whichever comes first. Use the Inspection Procedure or contact Altec to perform the inspection. 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.
