TO THE READER
This Workshop Manual has been prepared to provide servicing personnel with information on the mechanism,
service and maintenance of KIOTI tractors CH20, CK20J, CK20H and CK20HJ. It is divided into two parts, “Mecha-
nism” and “Servicing” for each section.
„
„
„
„
„ MECHANISM
Information on the construction and functions are included. The part should be completely understood before
proceeding with troubleshooting, disassembling or servicing.
„
„
„
„
„ SERVICING
In this section you will find general precautions, maintenance and special tools. The are other sections which
include troubleshooting, servicing, specifications lists, disassembling, assembling and servicing that explains in
detail procedures, precautions, factory specifications and acceptable limits.
This manual contains the latest production information on illustrations and specifications based on the most up to
date production information available at the time of publication.
We reserve the right to make changes throughout the entire manual at any time without notice.

SAFETY STARTING
1. Always use the safety start switch to start the en-
gine and never by any other means.
2. Do not alter or remove any part of machine safety
system.
3. Before starting the engine, make sure that all shift
levers are in neutral positions or in disengaged
positions.
4. Never start the engine unless you are in the
operator’s seat.

This symbol, the industry’s “Safety Alert Symbol”, is used throughout this manual and the decals on the machine
itself to warn of the possibility of personal injury. It is essential that you read the instructions and safety regulations
before you attempt to repair or operate this unit. Read these instructions carefully.

DESCRIPTION
This mark indicates hazardous situation which, if not observed, may
result in death or fatal injury.
This mark should be indicated for most dangerous situations only.
This mark indicates potentially hazardous situation which, if not
observed, may result in death or moderate injury.
This mark indicates potentially hazardous situation which, if not
observed, may result in minor or moderate injury. And this mark can be
used as a warning against unsafe activities.
This mark indicates emphasis on notable characteristics in working
procedures or information on working procedures and technology for
convenient use.
NOTE Gives helpful information.
BEFORE SERVICING AND REPAIRING
1. Read all safety instructions in this manual and be
aware of the safety decals on your machine itself.
2. Thoroughly clean your work area and the machine.
3. Make sure the machine is on firm and level ground
and that the parking brake is set.
4. Lower the implement to the ground.
5. Stop the engine and remove the key.
6. Disconnect the negative battery cable.
7. Place a “DO NOT OPERATE” tag in operator station.

S196-WOO Jul. 2003
SAFETY WORKING
1. Do not operate or service the machine while under
the influence of alcohol, medication, or other
substances.
2. Never wear loose fit clothing and always use safety
equipment appropriate to the job.
3. Never use improvised tools, parts or procedures.
Use only recommended tools appropriate to the
work.
4. Be careful to perform all work safely when servicing
is done by two or more people.
5. Always support the machine by safety stands. Never
work under the machine that is supported solely by
a jack.
6. Do not touch any rotating or hot parts while the en-
gine is running.
7. Never remove the radiator cap while the engine is
running, or immediately after stopping. Only remove
radiator cap when cool enough to touch with bare
hands. Slowly loosen the cap to relieve pressure
before removing completely.
8. Escaping fluid (fuel or hydraulic oil) under pressure
can penetrate the skin causing serious injury.
Relieve pressure before disconnecting hydraulic or
fuel lines. Tighten all connections before applying
pressure.
196W003A
196W004A
AVOID FIRES
1. Never smoke or allow flames or sparks in your work-
ing area, as fuel is extremely flammable and explo-
sive under certain conditions.
2. Always disconnect the negative battery cable first
and reconnect it last to avoid sparks from an acci-
dental short circuit.
3. Battery gas will ignite. Keep sparks and open flame
away from the top of battery, especially while
charging.
4. Be careful not to spill fuel on the engine.
196W005A

DISPOSE OF FLUIDS PROPERLY
1. Observe relevant environmental protection regula-
tions when disposing of oil, fuel, coolant, electro-
lyte and other harmful waste. Never pour fluids into
the ground, down a drain, or into a stream, pond, or
lake.
196W008A
VENTILATE WORK AREA
1. Exhaust contains poisonous carbon monoxide so
you should never run the engine in a closed area. If
the engine must be running while performing
maintenance, make sure the area is well ventilated.
PREVENT ACID BURNS
1. Sulfuric acid in battery electrolyte is poisonous. It is
strong enough to burn skin, clothing and cause
blindness if splashed into eyes. Keep electrolyte
away from eyes, hands and clothing. If you spill elec-
trolyte on yourself, flush with water, and get medi-
cal attention immediately.

(5) Reciprocating
(6) Rotating
1. Place the tractor on the flat surface for adjustment
or service.
2. Please work with the engine stop except for the case
that must be worked with the engine running.
3. Arrange each part properly on the clean space for
disassembly. For bolts and nuts, tighten manually
by hand to its original position.
4. Use only the approved special tool. For the tool that
is not used often, use the tool made by each ser-
vice workshop.
5. Use only part cleaning agent for manufacturing
when any part needs to be clean. Do not use the
diesel oil for cleaning to prevent any pollution. Use
only approved fluid oil for cleaning any hydraulic part.
6. Be careful not to attach any dust or metal chip etc.
for disassembly and assembly of any hydraulic part.
7. For measuring any part, remove any oil or polluted
material before performing the measurement.

moving or installing the live components.
9. Use only the DAEDONG genuine part for replace-
ment to maintain the performance and safety.
10.Replace the packing bearing and O-ring as new
part. Apply the grease properly for O-rings and oil
seals before assembly.
• Use the packing bond as three bond 1208D or
LOCTITE product.
• For using any packing bond, remove any re-
mained bond in the part before apply.
• Apply the bond in center of the flange between
bolt holes of the contact surface and apply the
inner surface for bolt hole portion.
• Perform the assembly within 10 minutes after
apply and inject oil after passing 30 minutes
above.
