5-4. Preventive Maintenance Checks and Service
5-4.1 Introduction
These checks and services have been provided to help you keep your equipment in good operating condition and
in service.
The preventive maintenance section is intended to formally maintain and document the aerial device on a regular
schedule. This schedule is intended as a minimum and is greatly dependent on operating conditions. Heavy use
and extreme environmental conditions such as heat, cold, sand, or salt spray will demand increased inspection and
maintenance.
This preventive maintenance section is not intended to replace or negate any routine pre-operation safety
inspections. The aerial operator must be aware of the condition of the aerial equipment before
operating. A pre-
operational visual safety inspection should always
be performed, including checking stabilizers, aerial pivot pins &
retaining hardware, cables, sheaves, basket pivot pins, retaining hardware, etc.
An Equipment Inspection and Maintenance Worksheet should be completed each time an inspection is performed.
A blank worksheet follows this section of the manual. (Additional worksheets may be photocopied.) A copy of the
completed worksheet should be retained by the customer as a permanent record of the maintenance actions
performed.
During the warranty period, and thereafter, inspections and maintenance schedules must be performed according
to the specified Pierce Manufacturing Inc. standards.
Failure to comply with these requirements will be considered grounds or conditions that may void the warranty on
individual components, assemblies, or the entire Pierce aerial device.
