ISEKI TRACTORS MODEL TU320F & TU324F
OPERATION MANUAL

TU320F & TU324F
Introduction
This operator's manual is intended to provide necessary information for operating and main-
taining your tractor. Its primary purpose is to offer you guidance in the lubrication and adjust-
ment
of your tractor during daily and seasonal operation.
We especially wish to call your attention to the many safety advisories listed in this manual.
Although your tractor is designed with safety of operation in mind, the risk
of accidents cannot
be completely eliminated unless you understand and practice all safety precautions.
Timely service saves costly repairs and valuable time lost because of breakdowns. When it
becomes necessary to make repairs or replacements to your tractor, be sure to insist on genuine
ISEKI parts. These parts are designed specially for your tractor under controlled specifications,
to provide satisfaction and the long lasting service to which you are entitled. Your dealer can
supply you with the parts you require. Use
of other than genuine ISEKI parts may jeopardize
our normal warranty. For additional information consult your dealer.
By the way, we want to understand that the contents of this manual may be somewhat different
from the standards pertaining to the machine that you actually own. This is because we are
always aiming to improve our technical and qualitative standards, and we are very quick to
introduce into our machines
of the improvements.
Please adhere strictly to instructions given in the text accompanied by this
mark as well as "GENERAL PRECAUTIONS." Failure to do so could lead to
physical injuries.

8. Parking and storing the
machine
I) Park the machine on hard,
level ground and provide
sufficient safety measures by
grounding the implement, re-
moving the key, applying the
parking brakes, etc.
2) After operation, inspect and
service the machine for the
next operation.
If the previous
operation has required the use
of fire, be sure that the fire has
been extinguished completely.
3) When storing the machine,
take measures to prevent it
from moving accidentally.
The machine should be stored
in a garage or covered with
tarpaulin or the like to prevent
access to it.
When covering the machine
with tarpaulin, wait until the
heated parts like the muffler
have cooled down completely.

There are two brake pedals to
control each brake independ-

pedal is depressed, the brake
on the right-hand rear wheel is
applied. Conversely, the left-
hand pedal operates the brake
on the left-hand rear wheel.
