7.0 Care And Maintenance – [cont’d]
7.2 Equipment Maintenance Log
The importance of frequent inspections along with
regular maintenance and accurate record keeping
cannot be overemphasized. Keep records of
equipment maintenance and services performed.
This is helpful if warranty coverage is ever in
question. Records should include:
Date of service and hour meter reading
Details of the service, maintenance or repair
performed.
Names of persons performing the service,
maintenance or repair
Copy of the purchase order or invoice, including
part numbers used in the repair
7.3.1 Housing Box Inspection – Daily Start of Shift
Inspect the housing box for cracks and wear.
Frequent raking of material will lead to a higher rate
of wear. Build-up worn areas and promptly repair
cracks to prevent further spreading. Neglecting or
delaying repairs will lead to further damage and
increased repair costs.
7.3.2 Vibration Dampening Inspection
Fig. 7-1 Buffers, Wear Plates
A system of buffers, dampers and guide plates help
minimize vibrations to the carrier and unwanted noise
by isolating the breaker from the housing box.
With guide plates in good condition, the breaker has
minimal movement inside the housing box. The
operator must actively monitor for excessive
movement. Never allow the breaker to contact the
housing. Worn isolators must be replaced
immediately. Minimize wear of these abrasion
resistant plates by using proper operating techniques
and keeping dust plugs and covers in place.

7.4 Front Head Inspection – Description of Parts
The aim of regularly inspecting these parts is to spot
problems and correct them in their early stages.
Ignoring inspections or failure to complete
maintenance when repairs are minor can quickly
escalate into extensive damage and higher repair
costs.
