SAFE OPERATION
34. Replace damaged or illegible safety labels. See
following page for required labels.
35. Do not modify, alter, or permit anyone else to modify
or alter the loader, any of its components, or any
loader function without first consulting a KUBOTA
Dealer.
36.Assemble, remove and reinstall the loader only as
directed in this manual. Failure to do this could result
in serious personal injury or death.
37.When operating another implement on a hillside, be
sure to remove the loader to reduce the risk of roll
over.
38. Never lift or pull any load from any point of the loader
with a chain, rope, or cable. Doing so could cause a
roll over or serious damage to the loader.
39.When a front loader is mounted on the tractor, enter
and exit the operator's seat only from left side of the
tractor.

REAR BALLAST
CAUTION
To avoid personal injury:
o For tractor stability and operator's safety, rear
ballast should be added to the rear of the tractor in
the form of 3-point counter weight and rear wheel
ballast. The amount of rear baltast will depend on
the application.
lmplement as Counter Weight
6'Box Scraper Approx. 450 kg (990 lbs.)
Rotary Tiller Approx. 240 kg (530 lbs.)
Back Hoe Approx. 770 kg (1690 lbs.)
ILiquid ballast in reartires
Water and calcium chloride solution provides a safe and
economical ballast. Used properly, it will not damage tires,
tubes or rims. The addition of calcium chloride is
recommended to prevent the water from freezing. Use of
this method of weighting the wheels has full approval o{
the tire manufacturers. See Vour tire dealer for this
service.
Liquid weight per tire (75 Percent filled)
IMPORTANT:
. Do not fill tires with water or solution more than 75% ot

Insure that the tractor tires are properly inflated.
Refer to the tractor operator's manual for optional tires.

TEST OPERATION
6 CAUTION
To avoid serious personal injury:
. Keep engine speed at low idle during the test
operation.
a Escaping hydraulic fluid under pressure can
have sufficient force to penetrate skin, causing
serious personal injury.
Before disconnecting lines, be sure to relieve
all pressure.
Before applying pressure to system, be sure all
connections are tight and that lines, tubes and
hoses are not damaged.
Fluid escaping from a very small hole can be
almost invisible, Use a piece of cardboard or
wood, rather than your hands to search for
suspected leaks.
lf injured by escaping fluid, see a doctor at
once. Serious infection or allergic reaction will
develop if proper medical treatment is not
administered immediately.
NOTE:
o When the lever is at each corner position marked by
asterisk (-), boom and bucket cylinders work at the
same time. However, the position marked is not
recommended for scooping because of insufficient lift
force.
To begin test operation, slightly move the control lever
from the "N" position. Slowly raise the loader boom just
enough for the bucket to clear the ground when fully
dumped. Slowly work through the dump and roll back
cycles.
IMPORTANT:
o lf the boom or bucket does not work in the directions
indicated on the label, lower the bucket to the ground,
stop the engine, and relieve all hydraulic pressure.
Recheck and correct all hvdraulic connections.

PRE-OPERATION CHECK 11
REMOVING AIR FROM HYDRAULIC
SYSTEM
Repeat raising and lowering the boom and bucket
operations until all the air is removed from the system and
the system responds properly.
IMPORTANT:
. Do not move the control lever into float position when
the bucket is off the oround.

OPERATING THE LOADER
12 OPERATING THE LOADER
The loader should be operated with the tractor engine
speed depending on the application and the operator's
level of experience. Excessive speeds are dangerous,
and may cause bucket spillage and unnecessary strain on
the tractor and loader.
When operating in temperatures below -'1 'C (30 "F ), run
the tractor engine below 1200 rpm until the oil
temperature exceeds -1 'C (30'f ).
The following text and illustrations offer suggested loader
and tractor operating techniques.
A CAUTION
To reduce the possibility of roll over:
a lt is not recommended that the loader be
attached when operating another implement on
, ^ hillside.
IMPORTANT:
t When operating the loader in rough terrain,
remove the mower to avoid damage to the mower.
FILLING THE BUCKET
Approach and enter the pile with a level bucket
Ease control lever toward you and then back to rollback
and lift the bucket.
The rollback and lifting of the bucket will increase
efficiency because a level bucket throughout the lifting
cycle resists bucket lift and increases breakaway effort.
NOTE:
. Do not be concerned if the bucket is not completely
filled during each pass. Maximum productivity is
determined by the amount of material loaded in a
given period of time. Time is lost if two or more
attempts are made to fill the bucket on each pass.
