INTRODUCTION
The information in this Operator’s Manual was written to give the owner/operator assistance in preparing,
adjusting, maintaining and servicing of the paver. 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.
The use of this asphalt paver (referred to as paver throughout the rest of the manual) 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 operation of the equipment.
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. Fol-
lowing 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. “Right” and “left” are determined from a position standing on the screed and facing forward.
A storage compartment is provided on the unit for storing the Operator’s Manual. After using the manual,
please return it to the storage compartment and keep it with the unit at all times! If the machine is resold,
GEHL Company recommends that this manual be given to the new owner.
If this machine was purchased "used," or if the owner's address 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 notified directly in case of an important product issue, such as a safety update program.
The wide GEHL dealership network stands ready to provide any assistance that may be required, including
genuine 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 in “Model/Serial Number Information” on page 6, 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.
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
The above safety alert symbol means
ATTENTION! BE ALERT! SAFETY IS
INVOLVED! It stresses an attitude of “safety
awareness” and can be found throughout this
operator’s manual and on the paver.
Before operating the paver, read and study the
following safety information. In addition,
anyone who operates or works with the paver
must be familiar with these safety precautions.
Gehl Company always takes operator’s safety into
consideration during the design process. Guards
and shield are provided, protecting the operator
and bystanders from moving parts or other hazards.
Owners and operators must be alert, however,
because some areas cannot be guarded or shielded
without preventing or interfering with proper
operation. Additionally, this operator’s manual and
decals on the paver warn of additional hazards and
should be read and observed closely.
DANGER
“DANGER” indicates an imminently hazardous
situation that, if not avoided, will result in death
or serious injury.
WARNING
“WARNING” indicates a potentially hazardous
situation that, if not avoided, could result in
death or serious injury.
CAUTION
“CAUTION” indicates a potentially hazardous
situation that, if not avoided, may result in
minor injury or property damage. It also alerts
users to unsafe practices.
REMEMBER: It is the owner’s responsibility to
communicate information about the safe use and
proper maintenance of the paver! This includes
providing understandable interpretations of these
instructions for operators who are not fluent in
reading English.
Pavers should be operated only by qualified
operators. It is the responsibility of the operator to
read and understand this operator’s manual and to
follow correct operating procedures.
MANDATORY SAFETY
SHUTDOWN PROCEDURE
BEFORE cleaning, adjusting, lubricating or
servicing the paver:
1. Bring paver to full stop on a level surface.
NEVER park on a slope or hillside, but if it
is not possible to avoid, park across the
slope and block the tracks at both ends.
2. Place all controls in neutral.
3. Move the throttle to low idle.
4. Shut off the engine and remove the key.
5. Lower the hopper and screed assembly to
the “full down” position. Allow the screed
to cool before lowering for transport.
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 injury.
Safety Reminders
• User/operator safety practices are included in
this operator’s manual and are intended to
promote the safe operation of the paver. These
guidelines do not preclude the use of good
judgment, care and common sense as indicated
by the specific jobsite work conditions.
• It is essential that operators be physically and
mentally fit and free of mind-altering drugs
and chemicals.

918215/CP0407 16 Printed in U.S.A
SAFETY
(Continued)
• It is essential that operators be thoroughly
trained in the safe operation of the paver. Such
training should be presented completely to all
new operators and not condensed for those
claiming previous experience.
• Some illustrations in this manual may show
doors, guards and shields open or removed.
This is for illustration purposes only. Be sure
that all doors, guards and shields are in their
proper operating positions before starting the
engine to operate the paver.
Pre-operation Safety Reminders
• Always wear personal protective equipment
appropriate for the job and working conditions.
Hard hats, safety glasses, protective shoes,
gloves, reflective vests, respirators and ear
protection are examples of types of equipment
that may be required. Do not wear loose-fitting
clothing, long hair, jewelry or loose personal
items while operating or servicing the paver.
• Always check the job site for obstructions and
bystanders.
• Always perform a daily inspection of the paver
before using it. Look for damage, loose or
missing parts, leaks, etc.
• Walk around the paver and warn all nearby
personnel before starting the paver.
Operation Safety Reminders
• Do not use ether or other starting fluids to start
the paver engine. Doing so may void the
engine warranty.
• Do not attempt to move hot asphalt mix with
your hands or feet. Contact with hot asphalt
can cause serious skin burns.
• Do not allow minors or any unqualified
personnel to operate or be near the paver
unless properly supervised.
• Do not operate the paver in an enclosed area
without adequate ventilation. Internal
combustion engines deplete the oxygen supply
within enclosed spaces and may create a
serious hazard unless the oxygen is replaced.
• Do not leave the paver unattended with the
engine running. Always lower the hopper to
“full down” position, shut off the engine, and
place all controls in neutral before leaving the
paver.
• Do not jump off the paver. Do not dismount
from the paver while it is moving.
• Check paver for proper functioning of controls
before operating. Observe all gauges and
instruments, and correct any malfunctions
before operating.
• Do not lift the hopper if pushing a dump truck
with the paver. Damage to the paver/truck may
result.
Service Safety Reminders
• Never use your hands to search for hydraulic
fluid leaks. Use a piece of paper or cardboard
instead. 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 familiar
with this type of injury or gangrene may result.
• Never attempt to bypass the keyswitch to start
the engine. Only use the jump starting
procedure described in this manual. See
“Jump-starting” on page 57.
• Never use fuel for cleaning purposes.
• Always position the safety props up when
leaving the hopper raised for inspection,
cleaning or service.
