SECTION 5.
REGULAR
MAINTENANCE
GUIDE
To keep your tractor operating
in
the
top
condition and
to
assure
its
proper performance and reliability for a long
period
of
time, periodic inspection
is
indispensable.
If
your
tractor
is
not periodically serviced, the result will
be
such
that
its
performance and operating life will
be
reduced.
Also a major breakdown
is
more likely
to
occur, which will
entail much more expense
what
you would pay for regular
maintenance.
Maintenance and servicing are very important, however,
the procedure
is
very simple. Carry
out
daily checking,
greasing and periodic service
by
carefully following the
instructions given
in
this manual. I n addition
to
daily
inspection the following servicing must
be
carried out:
50-hour service
to
be carried
out
on
a new tractor.
A-service
..................
Service every 50 hours
B-service
..................
Service every 100 hours
C-service
..................
Service every 200 hours
D-service
..................
Service every
400
hours
NOTE
The tractor should always
be
kept clean. Before
greasing or removing the
oil
pan plug and filter cap,
be sure to wipe the surface clean. When using tools for
repairing inside the engine, transmission, fuel tank or
hydraulic unit, clean the tools before use.
Be
careful
especially when refueling.
If
dust or water gets
in
the
fuel, engine trouble
will
be
experienced, resulting
in
loss of power and the unexpected necessity of parts
replacement. The tractor should
be
serviced indoors
where there
is
plenty of room and it
is
as
clean
as
possible.
SERVICE SCHEDULE
Observe the following service schedule. This service
schedule
is
applied to tractors which are operated under
normal conditions. When your tractor
is
frequently operat-
ed
in
muddy places, greasing must
be
carried
out
more
frequently and when the tractor
is
often operated
in
dusty places, clean the air cleaner element and fuel filter
more frequently. Extra servicing must
be
carried
out
according
to
particular situation.
