2.6 BATTERY MAINTENANCE
TO AVOID INJURY FROM AN EXPLOSION, DO NOT SMOKE OR
ALLOW SPARKS OR A FLAME NEAR BATTERY DURING SERVIC-
ING.
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
cover.
5. Machine is provided with a jump start stud, located
on the battery tie down bracket. (See Diagram
Below)
2.7 TRACK ADJUSTMENT - ADJUST
PERSONAL INJURY OR DEATH CAN RESULT FROM GREASE
UNDER PRESSURE.
GREASE COMING OUT OF THE RELIEF VALVE UNDER PRES-
SURE CAN PENETRATE THE BODY CAUSING INJURY OR DEATH.
DO NOT WATCH THE RELIEF VALVE TO SEE IF GREASE IS
ESCAPING. WATCH THE TRACK OR TRACK ADJUSTMENT CYL-
INDER TO SEE IF THE TRACK IS BEING LOOSENED.
LOOSEN THE RELIEF VALVE ONE TURN ONLY.
IF TRACK DOES NOT LOOSEN, CLOSE THE RELIEF VALVE AND
CONTACT YOUR JLG DEALER.
NOTE: Keeping the track properly adjusted will increase the
service life of the track and drive components.
The track tension must be set according to the cur-
rent operating conditions. Keep the track as slack as
possible if the soil is heavy.
Before adjusting the track, ensure the machine is on
firm, level ground.
Make sure there are no objects under the tracks
which would make the adjustment measurements
inaccurate.
NOTE: For accurate measurements, the machine should be
driven forward before taking measurements.
Make sure the tracks are positioned properly on the
track carrier roller for accurate measurements.Refer
