CHECK AND MAINTENANCE
1. Lubricating loader
KUBOTA recommends the high quality grease
designated as the extreme pressure and containing the
Molybdenum disulfide. Recommended grease may
specify “
Moly EP ” on its label.
1. Lubricate all grease fittings every 10 hours of
operation. Also, lubricate the joints of the control-
lever-linkage every 10 hours.
2. Daily before operation, check the hydraulic fluid
level of the tractor. If the hydraulic fluid level is low,
add the hydraulic fluid as described in the
tractor
operator's manual . Also change the filter element
and the hydraulic fluid as recommended in the
tractor operator's manual .
2. Re-tightening main frame bolt
and nut
NOTE
• Before finally tightening all mounting hardware
of the loader, start the engine and apply down
pressure to the bucket until the loader raises
the front wheels slightly. Make sure that you
can rotate the mounting pins easily, and then
tighten all bolts and nuts.
After 20 to 30 hours of initial loader operation, re-
tighten all mounting bolts and nuts to the required
torque value as follows.
