2.6 TORQUE REQUIREMENTS
The Torque Chart (See Figure 2-7.) consists of standard
torque values based on bolt diameter and grade, also
specifying dry and wet torque values in accordance with
recommended 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
inspection or during operation until the proper service per-
sonnel can be notified. The Service and Maintenance
manual provides specific torque values and periodic
maintenance procedures with a listing of individual com-
ponents. Utilizing this Torque Chart in conjunction with the
preventive maintenance section in the Service and Mainte-
nance manual, will enhance safety, reliability and perfor-
mance 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-
ING.
ALWAYS WEAR EYE PROTECTION WHEN SERVICING BATTER-
IES, BATTERY POSTS, AND BATTERY TERMINALS. WASH
HANDS AFTER HANDLING BATTERY COMPONENTS.
Battery Maintenance
1. The battery is maintenance free except for occa-
sional battery terminal cleaning, as noted in the fol-
lowing.
2. Remove battery cables from each battery post one
at a time, negative first. Clean cables with acid neu-
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).
4. When all cables and terminal posts have been
cleaned, ensure all cables are properly positioned
and are not pinched. Close battery compartment
