• Some illustrations in this manual may show doors,
guards and shields open or removed for illustrative pur­poses only. BE SURE all doors, guards and shields are
in their proper operating positions BEFORE starting the
engine to operate the machine.

• To ensure safe operation, replace damaged or worn-out
parts with genuine Gehl service parts.

• Gehl units are designed and intended to be used ONLY
with Gehl Company attachments or approved referral
attachments. The Gehl Company cannot be responsible
for operator safety if the unit is used with non-approved
attachments.

• The terrain, engine speed, load carried, and abrupt con­trol movements can affect machine stability. If misused,

any of the above factors can cause the machine to tip,
throwing the operator forward or out of the unit,
causing death of serious injury. Therefore, ALWAYS

wear the seatbelt when operating the equipment.
Operate the controls smoothly and gradually at an appro­priate engine speed which matches the operating condi­tions.

• For additional stability when operating on inclines or
ramps, ALWAYS travel with the bucket and blade
towards the top of the incline.

* DO NOT raise or lower a loaded bucket suddenly.

Abrupt movements under load can cause serious instabil­ity.

• NEVER attempt to bypass the keyswitch to start the
engine. Use only the jump-starting procedure detailed in
the Maintenance section of this manual.

• NEVER use your hands to search for hydraulic fluid
leaks; use a piece of paper or cardboard. Escaping fluid
under pressure can be invisible and can penetrate the
skin and cause serious injury. If any fluid is injected
into your skin, see a doctor at once. Injected fluid MUST
be surgically removed by a doctor or gangrene may
result.

• Do not operate too close to an excavation or ditch. BE
SURE that the surrounding ground has adequate strength
to support the weight of the machine and the load.

• DO NOT smoke or have any spark producing equipment
in the area while filling the fuel tank or while working
on the fuel or hydraulic systems.

SAFETY INFORMATION

The GEHL®Company, in cooperation with the
Society of Automotive Engineers, has adopted

this Safety Alert Symbol to pinpoint precautions
which, if NOT properly followed, can create a safety haz­ard. This symbol means ATTENTION! BECOME
ALERT! YOUR SAFETY IS INVOLVED! It stresses an
attitude of “Heads Up For Safety” and can be found
throughout this Operator’s Manual and on the machine.

Before you operate this equipment, read and study the
following safety information. In addition, be sure that
every individual who operates or works with this equip­ment, whether family member or employee, is familiar
with these safety precautions.

The Gehl Company always considers the operator’s safety
when designing its machinery, and guards exposed moving
parts for the operator’s protection. However, some areas can­not be guarded or shielded in order to assure proper opera­tion.

The following safety words and symbols are used throughout
the manual and on the machine to warn of dangerous situa­tions.

DANGER

DANGER indicates an imminently hazardous
situation which, if not avoided, will result in
death or serious injury.

WARNING

WARNING indicates a potentially hazardous sit­uation which, if not avoided, could result in
death or serious injury.

CAUTION

CAUTION indicates a potentially hazardous sit­uation which, if not avoided, may result in
minor or moderate injury. May also alert
against unsafe practices.

GENERAL SAFETY INFORMATION

Safety Symbols & Terminology Safety Reminders

PRINTED IN U.S.A. 2-1 908147/0999

• When driving on or across roads, the machine must be
equipped according to the road/traffic laws, and these
laws must be observed.

• Adapt working speed to local visibility.

• The driving speed must be adapted to the road and
ground conditions.

• Particular attention is required when working on slopes.
Angle of inclination of machine for all directions of trav­el: for brief operation (2-3 minutes)–maximum of 30°;
for continuous operation–maximum of 25°.

• Unauthorized personnel must not start-up the machine.

• No one but the operator must be on the machine when in
use. PASSENGERS PROHIBITED!

• Use the towing bracket provided for towing the machine.

• The operating area, steps, and grips must be free of oil,
dirt, ice and unsecured objects.

• The proper working condition of the lighting system
must be checked before and while working in darkness.

• Always keep the windshield and windows clean. Poor
visibility can cause accidents.

• Operate the machine from the operator’s seat only. Wear
seatbelt which is provided.

• Control the machine cautiously and gradually until you
are fully familiar with all the controls and handling.

• Pay attention to all movements of machines and
machines in the working area.

• Personnel must not be in the working area. Never oper­ate equipment above people.

• Always wear appropriate protective clothing: hard hat,
work gloves, strong work shoes, reflective clothing.

• Make sure you have sufficient knowledge of the working
area; location of utility lines (water, gas, electric, etc.)
and load bearing capacity of the ground.

• Before working in the area of utility lines, contact the
proper authority to determine the measures required for
safety.

• Never dig underneath the machine. Support walls prop­erly when excavating or working in, or close to, trench­es.

• Never drive long distances with the working equipment
fully raised. Lowering the working equipment produces
improved visibility and improved weight distribution.

Safety Reminders (continued)

• Never drive across the incline on sloping ground.
Extreme caution is required when working across an
incline or changing direction.

• Never use the weight of the machine to obtain more
force when excavating. There is a risk overturning.

• Before starting up the machine or setting it in motion,
warn any personnel in the area.

• Attach a clearly visible, legible OUT OF SERVICE sign
when repair and adjustments are being performed on the
machine.

• Unless necessary for servicing the engine, the engine
hood must not be opened while the engine is running.

• Be familiar with the machine safety devices.

• The machine is not to be used to lift equipment or trans­port personnel.

• The excavator arm is not a ramming tool. Never attempt
to use the working equipment to drive piles or similar
items into the ground, or to flatten the ground.

• Never excavate while the machine is travelling. Never
move the machine to dig. Never slew with lowered
working equipment and never move the machine when
the working equipment is resting on the ground.

The machine has several components that operate at high
temperature under normal operating conditions, primarily the
engine and exhaust systems. Also, the electrical system, if
not properly maintained or is damaged, can arc or produce
sparks. These conditions make it extremely important to
avoid conditions where explosive dust or gasses can be ignit­ed by arcs, sparks or heat.

The machine must be cleaned on a regular basis to avoid the
buildup of flammable debris such as leaves, straw, etc.
Accumulated debris, particularly in the engine compartment,
poses a fire hazard.

The spark arrestor muffler is designed to control the emission
of hot particles from the engine and exhaust system, but the
muffler system still gets hot during operation. For this rea­son, it is extremely important not to operate the machine in
an area where explosive dust or gasses can contact the hot
exhaust.

• Do not use the machine where explosive gasses or dust
can be ignited by arcs, sparks, hot components or
exhaust gasses.

• The operator cab, engine compartment and engine cool­ing system must be inspected every day and cleaned if
necessary to remove any flammable debris.

Fire Prevention

PRINTED IN U.S.A. 2-2 908147/0999

Mandatory Safety Shutdown Procedure

Before leaving the machine:

1. Lower the working equipment to the ground and support
it securely.

2. Reduce throttle and turn off the engine.

3. Lock out controls by raising left control console.

4. Remove the ignition key and take it with you.

• Check all electrical wiring and connections for damage.

• Check fuel and hydraulic tubes, hoses and fittings for
damage and leakage. Tighten or replace any parts that
show leakage. Always clean fluid spills.

• Always the clean the machine before performing any
welding. Cover rubber hoses, battery and all other flam­mable parts. Keep a fire extinguisher near the machine
when welding.

• Stop the engine and let it cool before adding fuel.
