The information in this Operator’s Manual was written to give the owner/operator assistance in preparing, adjust-

ing, maintaining and servicing of the Telescopic Handler. More important, this manual provides an operating plan

for safe and proper use of the machine. Major points of safe operation are detailed in the SAFETY chapter of this

manual.

GEHL Company asks that you read and understand the contents of this manual

COMPLETELY and become familiar with the machine, before operating it.

This Telescopic Handler is primarily intended for use as a material handler. However, it may be equipped with an

optional system: the Personnel Work Platform (PWP) System, which is intended for use when lifting personnel.

When there is no other practical option available, this machine, when equipped with the PWP System, is approved

for use to lift personnel, but only with an approved work platform, with the PWP System activated, and in full com-

pliance with the “Mandatory Work Platform Safety Rules” (see SAFETY chapter).

The use of this Telescopic Handler is subject to certain hazards that cannot be eliminated by mechanical means,

but only by the exercise of intelligence, care and common sense. It is therefore essential to have competent and

careful operators, who are not physically or mentally impaired, and who are thoroughly trained in the safe opera-

tion of the equipment and the handling of the loads.

Throughout this manual information is provided that is set in italic type and introduced by the word IMPORTANT

or NOTE. Be sure to read carefully and comply with the message or directive given. Following this information

will improve operating and maintenance efficiency, help to avoid breakdowns and damage, and extend the

machine’s life. A chart of standard hardware torques is located in the back of this manual.

A storage pocket in the back of the seat is provided for storing the Operator’s Manual. After using the manual,

please return it to the pocket and keep it with the unit at all times! If this machine is resold, GEHL Company rec-

ommends that this manual be given to the new owner.

If this machine was purchased “used,” or if the owner’s addrress has changed, please provide your GEHL dealer

or GEHL Company Service Department with the owner’s name and current address, along with the machine model

and serial number. This will allow the registered owner information to be updated, so that the owner can be noti-

fied directly in case of an important product issue, such as a safety update program.

“Right” and “left” are determined from a position sitting on the seat and facing forward.

The wide GEHL dealership network stands ready to provide any assistance that may be required, including gen-

uine GEHL service parts. All parts should be obtained from or ordered through your GEHL dealer. Give complete

information about the part and include the model and serial number of the machine. Record the serial number in

the space provided on the previous page, as a handy record for quick reference.

GEHL Company reserves the right to make changes or improvements in the design or construction of any part

without incurring the obligation to install such changes on any unit previously delivered.

INTRODUCTION

GEHL Company, in cooperation with the Society of Automotive

Engineers, has adopted this

Safety Alert Symbol

to identify potential safety hazards, which, if not properly avoided, could

result in injury. When you see this symbol in this manual or on the

machine itself, you are reminded to BE ALERT! Your personal safety is

involved!

SAFETY

DANGER

“DANGER” indicates an imminently haz-

ardous 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. It may also alert to

unsafe practices.

Gehl Company ALWAYS takes the operator’s safety

into consideration when designing its machinery, and

guards exposed moving parts for his/her protection.

However, some areas cannot be guarded in order to

assure proper operation. Further, this Operator’s

Manual,and Safety Manual and decals on the machine

warn of additional hazards and should be read and

observed closely.

REMEMBER! It is the owner’s responsibility for com-

municating information on the safe use and proper

maintenance of this machine! This includes providing

understandable interpretations of these instructions

for operators who are not fluent in reading English.

It is the responsibility of the operator to read and

understand the Operator’s Manual and other informa-

tion provided and use the correct operating procedure.

Machines should be operated only by qualified opera-

tors.

MANDATORY SAFETY SHUTDOWN

PROCEDURE

BEFORE cleaning, adjusting, lubricating or ser-

vicing the unit:

1. Stop machine on a level surface. (Avoid parking

on a slope, but if necessary, park across the

slope and block the tires.)

2. Fully retract the boom and lower the attach-

ment tool to the ground. Idle engine for gradual

cooling.

3. Place controls in neutral and apply parking

brake.

4. Shut off the engine and remove the key.

ONLY when you have taken these precautions can

you be sure it is safe to proceed. Failure to follow

the above procedure could lead to death or serious

bodily injury.

The above Safety Alert Symbol means ATTENTION!

ALWAYS BE 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 itself.

Before operating this equipment, read and

study the following safety information. In

addition, be sure that everyone who operates

or works with this equipment is familiar with

these safety precautions.
