Unauthorized Modifications; Attachment Precautions; Mandatory Safety Shutdown Procedure; Operation Safety - Gehl 503Z Operator's Manual

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 instal-
lation instructions. Modifications, such as welding,
drilling or cutting, can weaken the structure and reduce
the protection it provides. A damaged protective struc-
ture cannot be repaired – it must be replaced.
For safety reasons, use only genuine service parts. For
example, using incorrect fasteners could lead to a con-
dition in which the safety of critical assemblies is dan-
gerously 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. ser-
vice department for information about attachment
approval and compatibility with specific machine mod-
els. Manitou Americas, Inc. cannot be responsible if
the machine is used with non-approved attachments.
Do not use the machine for any application or purpose
other than described in this manual.

Unauthorized Modifications

Any machine modification made without authorization
from Manitou Americas, Inc. could create a safety haz-
ard, for which the machine owner would be responsi-
ble.
Printed in U.S.A.
For safety reasons, use only genuine replacement ser-
vice parts. For example, using incorrect fasteners could
lead to a condition in which the safety of critical
assemblies is dangerously compromised.

Attachment Precautions

your dealer or the Manitou Americas, Inc. service
department for information on available one-way (sin-
gle-acting) and two-way (double-acting) piping/valv-
ing/auxiliary control kits. Because Manitou Americas,

ments that owners may want to install on their

patibility with optional kits.
