4-6. Preventive Maintenance Checks and Service
4-6.1 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 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 operator must be aware of the condition of the equipment before
operating. A pre-operational visual
safety inspection should always
be 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 device.
