INTRODUCTION
The information in this Operator’s Manual was written
to give the owner/operator assistance in preparing,
adjusting, maintaining and servicing the Compact
Excavator. More important, this manual provides an
operating plan for safe and proper use of the machine.
Major points of safe operation are detailed in Chapter 2
– Safety.
Read and understand the contents of this manual com-
pletely and become familiar with the machine before
attempting to operate it. Contact your dealer to obtain
additional manuals.
Throughout this manual, information is introduced by
the word Note or IMPORTANT. Be sure to read the
message carefully and comply with the message. Fol-
lowing this information will improve operating and
maintenance efficiency, help to avoid breakdown and
damage and extend the service life of the machine.
Do not use the machine for any application or purpose
other than described in this manual. Consult your
dealer before using special attachments or equipment
not approved for use with the machine. Any person
making unauthorized modifications is responsible for
the consequences.
The Gehl dealer network stands ready to provide any
assistance you may require, including genuine Gehl
service parts. All service parts should be obtained from

All table values are in lbs. (kg) and for a machine in a horizontal position on
firm ground without bucket.
If equipped with a bucket or other implements, lift capacity or tilt load is
reduced by bucket or implement weight.
Calculation basis: According to ISO 10567.
The excavator's lift capacity is restricted by the settings of the pressure relief
valves and the hydraulic system's stabilizing features.
Neither 75% of the static tilt load nor 87% of the hydraulic lift capacity is
exceeded.

All table values are in lbs. (kg) and for a machine in a horizontal position on
firm ground without bucket.
If equipped with a bucket or other implements, lift capacity or tilt load is
reduced by bucket or implement weight.
Calculation basis: According to ISO 10567.
The excavator's lift capacity is restricted by the settings of the pressure relief
valves and the hydraulic system's stabilizing features.
Neither 75% of the static tilt load nor 87% of the hydraulic lift capacity is
exceeded.

CHAPTER 2 – SAFETY
DANGER
WARNING
CAUTION
IMPORTANT
SAFETY ALERTS
Manitou Americas, Inc., in cooperation with the Society of Automotive Engineers (SAE), has adopted this
safety alert symbol: This warning symbol, used
with a “signal word,” indicates situations or conditions
that can cause injury or death if precautions are not followed. The signal words used with the safety alert symbol are:
“IMPORTA NT” is used to draw atten tion to
a procedure that must to be followed to prevent machine damage.
GENERAL SAFETY RULES
“CAUTION,” “WARNING,” and “DANGER,”
which indicate the level of risk and severity of hazards.
All three levels indicate that safety is involved.
Observe the precautions whenever you see the safety
alert symbol, no matter which signal word is used.
The following signal words are used throughout this
manual and on decals on the machine to warn of potential hazards:
The word “DANGER” indicates an imminently hazardous situation that, if not
avoided, will result in serious injury or
death.
The word “WARNING” indicates a potentially hazardous situation that, if not
avoided, could result in serious injury or
death.
Before operating the machine, first read and study the
safety information in this manual. Be sure that anyone
who operates or works on the machine is familiar with
the safety precautions. This includes providing
translations of the warnings and instructions for
operators who are not fluent in reading English.
It is essential that operators be thoroughly trained in the
safe operation of the machine and handling loads.
Operators must not be physically or mentally impaired.
Do not allow minors or unqualified personnel to
operate the machine, or to be near the machine unless
they are properly supervised. It is recommended that
the operator be capable of obtaining a valid motor
vehicle operator’s license.
Only trained and authorized personnel, with a full
awareness of safe procedures, should be allowed to
operate or perform maintenance or service on the
excavator.
Read the operator’s manual provided with each attachment before using it.
Use of the machine is subject to certain hazards that
cannot be eliminated by mechanical means, but only by
exercising intelligence, care and common sense. Such
hazards include: hillside operation, overloading, load
instability, poor maintenance, and using the machine
for a purpose for which it was not intended or designed.
The word “CAUTION” indicates a potentially hazardous situation that, if not
avoided. may result in minor or moderate
injury.
918070/FP0811 2-1 Printed in U.S.A.
Manitou Americas, Inc, always takes operator’s safety
into consideration during the design process. Guards
and shields are provided, which protect the operator
and bystanders from moving parts and other hazards.
Operators must be alert, however, because some areas
cannot be guarded or shielded without preventing or
interfering with proper operation.
Different applications may require optional safety
equipment. Users must evaluate the worksite hazards
and equip the machine and the operator as necessary.
The information in this manual does not replace any
applicable safety rules and laws. Before operating the
machine, learn the rules and laws for the local area.
Make sure the machine is equipped as required
according to these rules/laws.
Remember that some risks to your health may not be
immediately apparent. Exhaust gases and noise
pollution may not be visible, but these hazards can
cause permanent injuries.
Some photographs in this manual may show doors,
guards and shields open or removed for the purposes of
illustration only. Be sure all doors, guards, shields and
panels are in the proper operating positions before
starting the engine to operate the machine.
Do not modify the Falling Object Protective Structure
(“FOPS”) unless instructed to do so in approved installation instructions. Modifications, such as welding,
drilling or cutting, can weaken the structure and reduce
the protection it provides. A damaged protective structure cannot be repaired – it must be replaced.
For safety reasons, use only genuine service parts. For
example, using incorrect fasteners could lead to a condition in which the safety of critical assemblies is dangerously compromised.
The machine is designed and intended to be used only
with approved attachments. To avoid possible personal
injury, equipment damage or performance problems,
use only attachments that are approved for use on and
within the rated operating capacity of the machine.
Contact your dealer or the Manitou Americas, Inc. service department for information about attachment
approval and compatibility with specific machine models. Manitou Americas, Inc. cannot be responsible if
the machine is used with non-approved attachments.
For safety reasons, use only genuine replacement service parts. For example, using incorrect fasteners could
lead to a condition in which the safety of critical
assemblies is dangerously compromised.
Attachment Precautions
Optional kits are available through your dealer. Contact
your dealer or the Manitou Americas, Inc. service
department for information on available one-way (single-acting) and two-way (double-acting) piping/valving/auxiliary control kits. Because Manitou Americas,
Inc. cannot anticipate, identify and test all of the attachments that owners may want to install on their
machines, please contact Manitou Americas, Inc. for
information on approval of attachments, and their compatibility with optional kits.
MANDATORY SAFETY
SHUTDOWN PROCEDURE
Before leaving the machine:
1. Bring the machine to a complete stop on a level
surface. Avoid parking on an incline or a hillside,
but if this is not possible, park across the slope.
2. Lower the working equipment to the ground and
support it securely.
3. Run the engine at idle speed for a few minutes to
allow systems to cool after operation at full speed.
4. Turn the key fully counter-clockwise to shut off the
engine. Wait for all movement to stop.
5. Move the joysticks in all directions to verify the
hydraulic system is de-pressurized.
6. Lock out controls by raising left control console.
