INTRODUCTION
This repair manual provides the technical informa-
tion needed to properly service and maintain the
Models LS120 and LS125 skid steers. Use it
in
conjunction with the operator's manual which is
supplied with the skid steer. Keep both manuals
available for ready reference.
The LS120 and LS125 have many similarities with
the major differences being engine horsepower and
lifting capacity.
Whenever working on New Holland equipment, left
and right sides of the machine are determined by
standing behind the unit, looking in the direction
of
travel.
The easiest and least time-consuming removal,
disassembly, and reassembly procedures are
detailed
in
the manual. Modifying these procedures
i~
not recommended.
NewHolland skid steersaredesigned with emphasis
on safety for operator protection. However, careless
and negligent operation can still result
in
serious
injury to persons or damage to property. Be sure to
read and follow all safety instructions

following safety precautions at all times:
1.
For servicing, the skid steer should be on level
terrain, engine stopped with the wheels blocked
or
the entire skid steer solidly supported with
the wheels offthe ground before servicing any
component
of
the drive train.
2.
For servicing under the operator's seat,
remove the seat and pan assembly from the
skid steer.
3. Do
not
operate the skid steer unlesstheseat
is
in the operate position.
4.
Do
not
service the skid steer with a raised
boom unless the boom

debris.
Do not store oily rags; they can ignite and burn
spontaneously.
Keep a first aid kit and fire extinguisher handy.
Keep emergency numbers for doctors, ambulance
service, hospital, and fire department near your
telephone.
USE CARE AROUND HIGH-PRESSURE FLUID
LINES
Escapingfluid underpressurecan penetrate theskin
causing serious injury.
Avoid the hazard by relieving pressure before
disconnecting hydraulic or other lines.
Tighten all line connections before applying
pressure.
00-7
Check for leaks with a piece of cardboard.
Protect hands and body from high-pressure fluids.
Ifan accident occurs, see a doctorimmediately. Any
fluid injectedintotheskin mustbesurgicallyremoved
within a few hours or gangrene may result. Doctors
unfamiliar with this type of injury should reference a
knowledgeable medical source.
AVOID HEATING NEAR PRESSURIZED FLUID
LINES
Flammable spray can be generated by heating near
. pressurized fluid lines, resulting
in
severe burns to
yourself and bystanders.
Do not heat by welding, soldering, or using a torch
near pressurized fluid lines.
Pressurized lines can be accidentally cut or
damaged when heat goes beyond the immediate
flame area.
USE CARE IN HANDLING AND SERVICING
BATTERIES
Prevent Battery Explosions
Keep sparks, lighted matches, and open flame away
from the top ofthe battery. Battery gas can explode.
Nevercheck batterycharge byplacing ametal object
across the posts. Use a voltmeter or hydrometer.
Do notcharge afrozen battery; itmayexplode. Warm
the battery to 16° C (60° F).
A WARNING A
If any servicing or adjustments require the
battery to be disconnected, or welding is
required on the skid steer, disconnect the
(-)
negative ground cable. Failureto disconnectthe
battery
may
result in damage to the restraint
system and other electrical components.
If
welding on an attachment is required, first
remove the attachmentfrom the skid steer boom
attaching plate.

SECTION 00 -GENERAL INFORMATION
A WARNING A
Starting an engine with a booster battery
requires extreme care as batteries produce
explosive gases. The slightest spark can cause
an
explosion.
Followthese safety tips:
1. Always shield your eyes when charging
or
working near a battery. Always provide good
ventilation.
2.
Cover the battery with a piece
of
carpet
or
other heavy material.
Do
not
remove the
battery vent caps.

(-)
negative
terminal of the stronger battery.
5. Connectthe remaining
(-)
negativecable end
to the engine block or starter .ground
terminal.
6. Reverse this procedure when disconnecting
the booster.
USE SAFE SERVICE PROCEDURES
Wear Protective Clothing
Wear close-fitting clothing.
Wear safety glasses orface shield as required:
Wear other safety equipment appropriate to the job.
Wear earplugs or earmuffs as required.
SERVICE MACHINE SAFELY
Use caution when working around moving parts.
If
seNicing requires the boom to be
in
the raised
position, remove any attachment from the boom
mounting plate and support the boom on the boom
lock pins. If servicing requires the complete skid
00-8
steerto be
in
the supported position, supportthe unit
with adequate jack stands or blocking with all four
wheels off the ground.
Ifservicing requires the engine to be operated, raise
the machine and properly support the unit with
adequatejackstands or blocking with all four wheels
off the ground.
