ground before floating the lift arms. Floating the lift
arms when the bucket is raised could cause an
accident or injury from the bucket falling.
A Never move forward when the lift arms are in the
"float" position.
19.Never dig or shovel at high speed, which could cause
the operator to be thrown from the operator's cabin or
cause injury from hitting something when the machine
stops suddenly. Always operate the machine at low
speed, carefully checking the area in front of the load
you will be moving.
20.Never operate the machine with the bucket raised over
the heads of people. Accident or injury may occur from
objects falling from the bucket or the bucket itself
falling.
21.Beware of material falling from the bucket. Unstable
material in the bucket such as round, cylindrical, or
stacked items could fall from the bucket, causing
injury. Always move an unstable load with the bucket
lowered.
22.Any sudden movements of the machine such as
lowering or stopping of the attachment may cause it to
recoil and rollover. Pay particular attention when the
bucket is loaded.
23.Never exceed the maximum loading capability of the
bucket or put loads off-center of the bucket, which can
cause the machine to become unstable and rollover.
Page 12
SAFE OPERATION-4
24.Never attempt to undercut a high embankment.

could cause the ground to cave-in.
A Never operate in areas where there is a possibility of
falling rock.
A Never attempt to operate or drive the machine on
unstable surfaces such as cliffs, shoulder of roads,
deep trenches, etc. The machine could lose stability
from unstable ground or vibration underneath, causing it to rollover or fall.
(1) Ground surfaces are especially unstable after
heavy rain or explosions.
(2) Embankments and trenches may cause instabil-
ity of the ground around the area.
25.Always operate the machine a safe, low speed,
especially in congested or closed in areas where there
is a danger of hitting or running into something. Pay
close attention to obstructions
26.Pay particular attention when passing through tunnels
or moving the machine near high walls to avoid hitting
it and causing accident or injury.
Always check height and width dimensions of the
machine against tunnels or any other narrow spaces
through which the machine is to be moved in order to
avoid accident or injury from hitting an obstruction.
27.The machine is NOT designed for operation with
hanging loads and has no safety features for such
circumstances. Never operate in conjunction with a
crane or other such device, which could cause serious
injury.
C Safety for children
Tragedy can occur if the operator is not alert to the

A Make sure any loose connections are secure properly
before using the machine.
29.Fire prevention
Compact Track Loader and some attachments have
components that are at high temperatures under
normal operating conditions. The primary source of
high temperatures is the engine and exhaust system.
The electrical system, if damaged or incorrectly
maintained, can be a source of arcing or sparks.
The following fire prevention guidelines will help to
keep your equipment up and running efficiently and
keep the risk of fire to a minimum.
A Blow off all accumulated debris near hot engine
exhaust components such as turbocharger and
exhaust manifold as well as exhaust pipes and muffler
more frequently when working in severe conditions.
A Clean out all accumulated flammable debris such as
leaves, straw, pine needles, branches, bark, small
wood chips and any other combustible materials from
inside the machine belly pans or lower unit structures
as well as from area in proximity to the engine.
A Inspect all fuel lines and hydraulic hoses for wear or for
deterioration. Replace them immediately if they begin
to leak.
A Examine electrical wiring and connectors frequently
for damage. Repair any wires that are loose or frayed
before operating the machine. Clean all electrical
connections and tighten all electrical connections as
necessary.
A Inspect the exhaust system daily for any signs of
leakage. Check for broken pipes and muffler and also
for loose or missing bolts, nuts and clamps. If any
exhaust leaks or fractured parts are found, repairs
must be completed prior to operation.
A Always keep a multipurpose fire extinguisher on or
near the machine. Be familiar with the operation of the
fire extinguisher.
30.Take care when working around hot and pressurized
components.
A Always allow the engine to cool sufficiently before
performing any maintenance, inspection or repairs.
A Never touch any parts such as the engine, muffler,
radiator, hydraulic lines, sliding parts, etc. as they may
be very hot immediately after the machine has been
running and can cause burning. Allow these parts to
cool sufficiently before touching.
A Always use sufficient care whenever removing the
caps and plugs on the coolant, oil and hydraulic fluid
as they are hot and pressurized and can causing
burning and injury from spraying of hot fluid.
31.Make certain pressure from all of these systems is
sufficiently released before performing any
maintenance or repairs. Oil or other fluids could be
released when caps or filters are removed before the
pressure has been stabilized in the hydraulic system.
A Gradually release internal pressure build-up by
standing out of the line of any possible spray and
slowly removing plugs, screws or disconnect hoses.
Page 17
32.Always use care whenever handling grease that is
pressurized.
A Always follow the proper procedure to adjust tension.
Grease in the track adjuster is pressurized and
improper release can cause the discharge valve to fly
off, causing personal injury or death.
A Always loosen the discharge valve for the grease
slowly.
A Avoid standing in front of, or putting any parts of the
body in the line of the grease discharge valve.
A If no grease is released when discharge valve is
loosened, the machine has a malfunction. DO NOT
attempt to make any repairs yourself and contact the
nearest dealer for repairs. Any operation of the
machine under these conditions can be very
dangerous.
-9SAFE OPERATION
35.To avoid the possibility of battery explosion, do not use
or charge the refillable type battery if the fluid level is
below the LOWER (lower limit level) mark. Check the
fluid level regularly and add distilled water as required
so that the fluid level is between the UPPER and
LOWER levels.
36.To avoid sparks from an accidental short circuit,
always disconnect the battery's ground cable (-) first
and reconnect it last
33.Always carefully check the machine after performing
any maintenance or repairs. Confirm that no oil, water,
etc., is leaking from any parts that had been serviced
by carefully inspecting the parts. Gradually speed up
the engine from a low speed to higher speed to check
operation.
34.Waste material
A Always make sure any material and waste products
from the repair and maintenance of the machine are
collected into proper containers using a funnel, or
other device. Dispose of waste material properly to
avoid pollution and contamination of the environment.
A Consult local regulations and codes when disposing of
oil, fuel, engine coolant, refrigerant, solvents, filters,
batteries, and any other potentially harmful and
hazardous material or substance.

OPERATION OF THE MACHINE
RUNNING-IN OF THE MACHINE
The operation and care of the new machine influences its
life span. Your new machine has been carefully checked
and tested before leaving the factory. In spite of this, all
movable components must run-in during the first 50 work
hours. Do not work with full rpm's and full loads during this
period. It is most important to run-in your machine
properly in order to achieve its full performance and
longevity. During the running-in, the following points
should be adhered to in all cases.
BDo not Work with Full Engine Rpm's or
Full Loads during the First 50 Working
Hours
A Let the engine warm up sufficiently in the cold season.
A Do not let the engine rev-up more than necessary.
BOil Change in the Run-in Stage
The lubrication oil plays a specific and important role
during the run-in phase of the machine. The numerous
movable parts are not yet run-in, so many fine metal
particles can be generated and may cause damage and

41OPERATION OF THE MACHINE
IMPORTANT INFORMATION ON MACHINE
OPERATION
A Do not operate machine on loose rock or gravel (hard
or soft).
A Avoid moving machine when lift arms and bucket are
in the raised position. If you must move the machine
when they are raised, take care to travel at low speeds
in order to maintain control of the machine at all times.
A Always avoid working on an incline as the machine
can become unstable and rollover, causing serious
injury or death.
A Whenever the machine is in motion, keep the bucket
as close to the ground as possible. Never change
directions when the bucket is in the raised position.
A Always move the machine at speeds that are
appropriate to the conditions. Take particular care if
you are ever moving through areas where view may be
obstructed or when transporting hazardous material.
A Never operate the machine in the vicinity of explosive
gases. Always keep exhaust from machine away from
any combustible material.
A Never turn or spin the machine at high speed.
A Never approach an incline horizontally, which can
cause the track to slide off and cause excessive
wearing of tracks.
A Never exceed the operating capacity of the machine.
A Never use the machine to move material or perform
work that exceeds the capacity of the bucket or
attachments.
A Never use the bucket as a hammer to drive poles or
studs into the ground.
A Never attempt to dig too deeply with the bucket, which
can damage the bucket or lift arms.
A Avoid hitting the bucket against rocks or similar solid
material, which will damage the bucket or bucket
cylinder.
A Never fully extend cylinders to perform an operation.
Working while cylinders are fully extended can cause
damage from excessive force.
A Never scoop or grade areas while the tilt cylinders are
fully extended
Extremely heavy loads apply excessive traction force
to the bucket cylinders and can cause damage. Avoid
loads that are too heavy.
BCaution While Traveling
A Running over large debris (rocks, stumps, blocks, etc.)
may cause such debris to fly up and damage the
machine. Avoid such debris whenever possible.
A If obstacles cannot be avoided, travel slowly over them
with the bucket in the lowered position. Approach the
obstacles so it is at the center of the tracks.
Page 66
OPERATION OF THE MACHINE42
BPrecaution When Traveling in High Speed
A Whenever traveling over uneven ground surfaces,
travel at low speed. Avoid any sudden movements
with the machine such as accelerating, stopping, or
turning quickly.
BPrecautions for Use of Machine Near
Water
A Whenever working near water, pay particular attention
not to submerge any part of the machine especially the
rear where the radiator fan could be exposed to water,
damaging the parts. Always take care to keep working
machine parts out of water, especially when coming
out of a shoreline, for example, at a sharp angle.
A Permissible water depth:
Never allow the machine to become submerged in
water above the bottom of the body.
A Never allow the main body of the machine to become
submerged in water or sand. Contact your Kubota
Dealer or Service Outlet if the main body of the
machine is exposed to water.
BPrecaution When Traveling on Inclines
To avoid personal injury or death:
A Know and understand the machine capabilities
and operating conditions, and never exceed
any of these conditions. Keep in mind that poor
or difficult working conditions may reduce the
capability of the machine, requiring a reduction
in speed to maintain stability.
A Always lower the bucket to a height of 20 to 30 cm
from the ground whenever traveling on an incline.
Lower the bucket completely to the ground and stop
the machine in case of emergency.
A Always travel at low speed when moving on an incline.
Reduce the engine speed (rpm) when moving down
and incline and set the engine stroke to half or less
using the left control lever.
Traveling too fast down an incline can lead to loss of
control and accident or injury.
A Always make sure the heavy end of the machine is
facing up the incline when traveling either direction on
a hill having a gradient of 15 degrees or more.
A Whenever traveling on an incline, be careful of the
possibility of sliding sideways or rolling over.
A Never travel down an incline in reverse.
A Never approach an incline horizontally or diagonally.
Always return to a flat surface and redirect the
machine.
A Beware of unstable and slippery surfaces such as
grass, leaves, wet metal or ice. The machine can slide
very easily even on low grade inclines.
A If parts that require lubrication are exposed to water for
long periods of time, make sure they are re-lubricated
with grease to remove old grease.
A After working in the mud and in the water, make sure
that there is no invasion of the soil inside the frame.
If soil is deposited, you should clean the internal frame.
(See page 69, "Cleaning Inside of Main Frame".)
C Orientation of machine when traveling on an
incline
Page 67
A Braking is automatic with the HST system when the
left control lever is in the neutral position. Raise
armrests for parking brake.
C What to do when engine stops suddenly
A If the engine stops suddenly when moving down an
incline, put control levers into neutral, stop the
machine and then restart in the normal manner.
BParking on an Incline
A It is best to park the machine on firm, level ground
using the parking brake but if you must park the
machine on an incline, make sure you block it to
prevent any movement.
A Make sure the machine is highly visible when parking
near streets by using barriers, appropriate caution
signs, lights, etc. to avoid any accident or collision with
other vehicles.
A Always raise the armrests to the "RAISED" position
and stop the engine before leaving the operator's seat.
A Never leave the machine running unattended or with
the lift arms raised. Whenever lift arms are raised, they
MUST always be restrained using the lift arm stopper.
A Whenever leaving the machine, perform the following
procedure:
A Put control levers into neutral.
A Return the throttle lever to idle.
A Lower the bucket to the ground.
A Move armrest in the "RAISED" position.
A Turn off the engine and remove the key.
BProhibited Actions
Actions that MUST NOT be performed with the machine:
A Never move, transport material or operate the
machine in the following places:
Mud, broken stone, jagged or unstable base rock, iron
beams, iron scrapes, iron sheets, etc. Navigating,
turning and moving the machine over sharp material
may damage or break the tracks.
A Traveling on riverbeds and other areas where loose
gravel can get into the tracks, causing them to slip off
or become damaged.
A Do not use near the oceanfront where salt water can
corrode the various parts of the machine.
A Always prevent fuel, oil, salt or other chemical agents
from getting into the tracks, which can cause corrosion
to the metal track cores. If the track and its parts are
exposed to such material, immediately remove by
using water.
A Always avoid traveling on roads directly after they
have been resurfaced or other hot surfaces such fire
or metal surfaces under direct sunlight. Excessive
heat can cause irregular wear and damage to tracks.
A Do not attempt to move material where the surface is
unstable and could cause slippage in the tracks.
Unnecessary and excessive slipping of tracks will
damage and cause abnormal wearing of the tracks.
43OPERATION OF THE MACHINE
To avoid personal injury:
A Whenever operating the machine, do the
following:
1) Always avoid sudden changes in direction, or
spinning on concrete surfaces. Excessive
friction on the tracks will cause them to wear
out or become damaged.
2) Always avoid sudden impact to the tracks
such as allowing the machine to drop down or
hit objects.
3) Chemical such as salt, potassium chloride,
ammonium sulfate, potassium sulfate, triplesuper phosphate of lime, etc., can damage the
track belts. If the tracks are exposed to any of
these substances, immediately wash
thoroughly with water.
4) Avoid scraping the rubber tracks along
concrete, and other rough surfaces.
5) Take particular care when operating,
transporting material or traveling in snowy
conditions or on ice as tracks may slip.
6) Operate the machine between -20 C and
+50 C (-4 to 122 F) for proper functioning of
rubber track belts.
7) If machine must be stored for 3 months or
longer, keep it indoors, out of direct sunlight
and prevent exposure to the elements to
prevent wear on the rubber tracks.
BPreventing Slippage of Rubber Tracks
Always do the following to prevent slippage of rubber
tracks:
A Make sure tracks are kept at the proper tension. Never
change directions when there is excessive slack in the
track belts.
A When ascending an incline, never change direction at
the base of the incline.
A Always avoid operating the machine with one track on
a different surface than the other track, or with one
track partially on an incline. Make sure both tracks are
on stable, firm surfaces when in motion.

BChecking Battery Condition
To avoid the possibility of a battery explosion:
For refillable type battery, follow the instructions
below.
A Do not use or charge the refillable type battery
if the fluid level is below the LOWER (lower limit
level) mark. Otherwise, the battery component
parts may prematurely deteriorate, which may
shorten the battery's service life or cause an
explosion. Check the fluid level regularly and
add distilled water as required so that the fluid
level is between the UPPER and LOWER levels.
To avoid personal injury:
A Never remove the vent caps while the engine is
running.
A Keep electrolyte away from eyes, hands and
clothes. If you are spattered with it, wash it
away completely with water immediately and
get medical attention.
A Wear eye protection and rubber gloves when
working around the battery.
A Before inspection or dismounting the battery,
be sure to turn off the engine and turn the
starter switch to the "OFF" position.
A When removing the battery, always disconnect
the negative ground cable first. When installing
a battery, always connect the ground cable
last. This prevents a possible explosion caused
by sparks.
A Always wear eye protection when working with
the battery.
The factory-installed battery is of non-refillable type.
If the indicator turns white, do not quick charge the
battery but replace it with new one.
Mishandling the battery shortens the service life and adds
to maintenance costs.
The original battery is maintenance free, but needs some
servicing.
If the battery is weak, the engine will be difficult to start
and the lights will be dim. It is important to check the
battery periodically.

from the battery at all times, especially when
charging the battery.
A When charging the battery, ensure the vent
caps are securely in place. (if equipped)
A When disconnecting the cable from the battery,
start with the negative terminal first.
When connecting the cable to the battery, start
with the positive terminal first.
A Never check battery charge by placing a metal
object across the posts.
Use a voltmeter or hydrometer.
1. To slow charge the battery, connect the battery
positive terminal to the charger positive terminal and
the negative to the negative, then recharge in the
standard fashion.
2. A boost charge is only for emergencies. It will partially
charge the battery at a high rate and in a short time.
When using a boost-charged battery, it is necessary to
recharge the battery as early as possible.
Failure to do this will shorten the battery's service life.
3. The battery is charged if the indicator display turns
green from black.
