SCHEDULED MAINTENANCE
Scheduled maintenance and periodic inspec-
tions are two very ilnportant functions which
every owner and/or operator must follow to as-
sure the rnaxirnurn performance of the unit.
Scheduled
POINT OF INSPECTION

LUBRICATION
Thorough lubrication service performed at
definite intervals and according to an established
routine will aid greatly in prolonging the life of
the tractor equipment and in reducing operating
expense. In the "LUBRICATION GUIDES" the
recommended intervals between lubrication per-
iods are approximate, based on average operat-
ing conditions. The type of work being done,
load, ground and weather conditions are all fac-
tors to consider in frequency of lubrication. The
life and performance of a machine depend on the
care that it is given. - .P}'oper lubrication is the
most important maintenance service for your
equipment. ~
Regular lubrication at recommended inte r-
vals also pr'ovide:s an opportunity for a general
routine inspection of the equipment.
Periodic.
Inspect for wear or kinking, Refer to
"REEVING, "
Inspect for loose or broken cap screws, nuts
or pins,
Inspect for wear, Refer to "CUTTING EDGES
AND END BITS,II
Tighten.
More frequent lubrication is required under
adverse operating conditions such as excessive-
ly high or low temperatures, continued opera-
tion in sand or dust, immersion in water or ex-
posure to moisture. Anyone of these conditions
may quickly destroy the protective qualities of
the lubricants.
All lubrication fittings are 1/8 inch fittings.
At all temperatures
use a chassis lubricant to
lubricate all fittings. Before applying the lu-
bricant, clean all the fittings to avoid forcing
dirt or abrasives into the working parts. Ap-
ply the new lubricant until the old lubricant is
forced through the bearing and starts to seep
out the edges, of the bearing lubricated.
