2.6 TORQUE REQUIREMENTS
The Torque Chart (Figure 2-7.) consists of standard torque
values based on bolt diameter and grade, also specifying
dry and wet torque values in accordance with recom-
mended shop practices. This chart is provided as an aid
to the operator in the event a condition is noticed that
requires prompt attention during the walk-around inspec-
tion or during operation until the proper service personnel
can be notified. The Service and Maintenance manual
provides specific torque values and periodic maintenance
procedures with a listing of individual components. Utiliz-
ing this Torque Chart in conjunction with the preventive
maintenance section in the Service and Maintenance
manual, will enhance safety, reliability and performance of
the machine.
2.7 BATTERY MAINTENANCE
TO AVOID INJURY FROM AN EXPLOSION, DO NOT SMOKE OR
ALLOW SPARKS OR A FLAME NEAR BATTERY DURING SERVIC-

tralizing solution (e.g. baking soda and water or
ammonia) and wire brush. Replace cables and/or
cable clamp bolts as required.
3. Clean battery post with wire brush then re-connect
cable to post. Coat non-contact surfaces with min-
eral grease or petroleum jelly (Vaseline).

cleaned, ensure all cables are properly positioned
and are not pinched. Close battery compartment
cover.
