SAFETY

This safety alertsymbol 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 decals on the machine.

Before operating this machine, read and study the following safety information. In addition, be sure that everyone who operates or works with this machine, whether family member or employee, is familiar with these safety precautions. It is essential to have competent and careful operators, who are not physically or mentally impaired, and who are thoroughly trained in the safe operation of the machine and the handling of loads. It is recommended that the operator be capable of obtaining a valid motor vehicle operator’s license.

The use of skid steer loaders is subject to certain hazards that cannot be eliminated by mechanical means, but only by exercising intelligence, care and common sense. Such hazards include, but are not limited to, hillside operation, overloading, instability of the load, poor maintenance and using the equipment for a purpose for which it is not intended or designed.

Gehl

ALWAYS considers the operator’s safety when designing its machinery

and guards exposed moving parts for the operator’s protection. However, some areas cannot beguarded or shielded in order to assure proper operation. Furthermore, this Operator’s Manual and the decals on the machine warn of additional hazards and they should be read and observed closely.

Some photographs in this manual may show doors, guards and shields open or removed for illustrative purposes only. Be sure that all doors, guards and shields are in their proper operating positions before starting the engine to operate the unit.

Different applications may require optional safety equipment, such as a back-up alarm, horn, mirror, strobe light or an impact-resistantfront door. Be sure you know the job site hazards and equip your machine as needed.

DANGER

Mandatory Safety Shutdown Procedure

Before cleaning, adjusting, lubricating, servicing the unit or leaving it unattended:

1. Move the drive control handle(s) to the neutral position.

2. Lower the lift arm and attachment completely. If the lift arm must be left

in the raised position,

BE SURE to properly engage the lift arm support

device (page 17).

3. Move the throttle to the low idle position, shut off the engine and remove the key.

4. Before exiting, move the lift/tilt control(s) to verify that the controls do not cause movement of the lift arm and hitch.

Safety Reminders

Before Starting

Ü Do not modify the ROPS/FOPS unless instructed to do so in installation

instructions. Modifications such as welding, drillingor cutting can weaken the structure and reduce the protection it provides. A damaged ROPS/FOPS cannot be repaired — it must be replaced.

Ü To ensure safe operation, replace damaged or worn-out parts with genuine

Gehl service parts.

Ü Gehl skid steer loaders are designed and intended to be used onlywith Gehl

attachments or approved referral attachments. Gehl cannot be responsible for operator safety if the loader is used with a non-approved attachment.

Ü Remove all trash and debris from the machine each day, especially in the

engine compartment, to minimize the risk of fire.

Always face the loader and use the hand holds and steps when getting on and off the loader. Do not jump off the loader.

Never use starting fluid (ether).

Walk around the machine and warn allnearby personnel before starting the machine.

Always perform a daily inspection of the machine before using it. Look for damage, loose or missing parts, leaks, etc.

During Operation

Machine stability is affected by: the load being carried, the height of the load, machine speed, abrupt control movements and driving over uneven terrain.

LOADER TO TIP, THROWING THE OPERATOR OUT OF THE SEAT OR LOADER, RESULTING IN DEATH OR SERIOUS INJURY. ALWAYS operate with the seatbelt fastened and the restraint bar lowered.

DISREGARDING ANY OF THESE FACTORS CAN CAUSE THE

Therefore,

Do not exceed the machine’s Rated Operating Load. Carry the load low. Move the controls smoothly and gradually, and operate at speeds appropriate for the conditions.

908274/BP1202 6

Always travel with the heavier end of the loader toward the top of the

incline for additional stability when operating on inclines or ramps. Do not raise or drop a loaded bucket or fork suddenly. Abrupt movements

under load can cause serious instability. Never push the lift control into the “float” position with the bucket or

attachment loaded or raised, because this will cause the lift arm to lower rapidly.

Do not drive too close to an excavation or ditch; be sure that the

surrounding ground has adequate strength to support the weight of the loader and the load.

Never carry riders. Do not allow others to ride on the machine or

attachments, because they could fall or cause an accident. Always look to the rear before backing up the skid steer loader.

Operate the controls only from the operator’s seat.

Always keep hands and feet inside the operator’s compartment while

operating the machine.

Ü New operators must operate the loader in an open area away from

bystanders. Practice with the controls until the loader can be operated safely and efficiently.

Ü Exhaust fumes can kill. Do not operate this machine in an enclosed area

unless there is adequate ventilation.

Ü When you park the machine and before you leave the seat, check the

restraint bar for proper operation. The restraint bar, when raised, deactivates the lift/tilt controls and auxiliary hydraulics, and applies the parking brake.

Maintenance

Never attempt to by-pass the keyswitch to start the engine. Use only the jump starting proceduredetailed in theOperation chapter ofthis manual.

Never use your hands to search for hydraulic fluid leaks. Instead, 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.

Always wear safety glasses with side shields when striking metal against metal. In addition, it is recommended that a softer (chip resistant) material be used to cushion the blow. Failure to heed could lead to serious injury to the eyes or other parts of the body.

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.

Potential Hazards

A skid steer loader operator must

ALWAYS be conscious of the working

environment. Operator actions, the environmental conditions and the job at hand require thefull attention ofthe operator sothat safetyprecautions can be taken.

ALWAYS maintaina safe distance from electric power lines andavoid contact

with any electrically charged conductor or gas line. Accidental contact or rupture can result in electrocution or an explosion. Contact the North American One CallReferral System at(888) 258-0808 forthe local "Digger's Hotline" number or the proper local authorities for utility line locations

BEFORE starting to dig!

Exposure to crystalline silica (found in sand, soil and rocks) has been associated with silicosis,a debilitating andoften fatal lung disease. A Hazard Review (Pub. No. 2002-129) by the U.S. National Institute for Occupational Safety and Health(NIOSH) indicates a significant risk of chronicsilicosis for workers exposed to inhaled crystalline silica over a working lifetime. NIOSH recommends an exposure limit of 0.05 mg/m

as a time-weighted average for up to a 10-hr workday during a 40-hr workweek. NIOSH also recommends substituting less hazardous materials when feasible, using respiratory protection and regular medical examinations for exposed workers.

Safety Decals

The skid steer loader has decals that provide safety information and precautions around the loader. These decals must be kept legible. If missing or illegible, they must be replaced promptly. Replacements may be obtained from your Gehl dealer. New equipment must have all decals specified by the manufacturer affixed to their proper place.

New Decal Application

Surfaces must be free of dirt, dust, grease and foreign material before applying the decal. Remove the smaller portion of the decal backing paper and apply the exposed adhesive to the clean surface, maintaining proper position and alignment. Peel the rest of the backing paper and apply hand pressure to smooth out the decal surface. Refer to the following pages for proper decal location. Text decals begin on page 9; no-text decals begin on page 12.
