Operator’s Manual

INTRODUCTION
This Operator’s Manual gives the owner/operator information about
maintaining and servicing SL3635 and SL3935 skid steer loader models.
More importantly, 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.
We ask that you read and understand the contents of this manual completely
and become familiar with your new machine before operating it. See your
authorized Gehl dealer if you have any questions concerning information in
the manual, require extra manuals or for information concerning the
availability of manuals in other languages.
Throughout this manual, information is provided which is set in italic type
and introduced by the word Note or Important. Read carefully and comply
with the message — it will improve your operating and maintenance
efficiency, help avoid breakdowns and damage, and extend your machine’s
life.
A manual storage box in the operator’s compartment holds the Operator’s
Manual and EMI Safety Manual. Please return the manuals to this box and
keep them with the unit at all times. If this machine is resold, we recommend
that these manuals be given to the new owner.
The attachments and equipment available for use with this machine have a
wide variety of potential applications. Read the manual provided with the
attachment to learn how to safely maintain and operate the equipment. Be
sure the machine is suitably equipped for the type of work to be performed.
Do not use this machine for any applications or purposes other than those
described in this manual or applicable for approved attachments. If the
machine is to be used with special attachments or equipment other than those
approved by Gehl Company, consult your Gehl dealer. Any person using
non-approved attachments or making unauthorized modifications is
responsible for the consequences.
The Gehl dealership network stands ready to provide you with any assistance
you may require, including providing genuine Gehl service parts. All service
parts should be obtained from your Gehl dealer. Give complete information
about the part and include the model and serial numbers of your machine.
Record these numbers in the space provided on the Table of Contents page, as
a handy reference.
Please be aware that Gehl strives to continuously improve its products and
reserves the right to make changes and improvements in the design and
construction of any part without incurring the obligation to install such
changes on any unit previously delivered.

SAFETY
This safety alert symbol 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 be guarded 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-resistant front door. Be
sure you know the job site hazards and equip your machine as needed.
“DANGER” indicates an imminently hazardous
situation which, if not avoided, will result in death or serious
injury.
“WARNING” indicates a potentially hazardous
situation which, if not avoided, could result in death or serious
injury.

DANGER
WARNING

“CAUTION” indicates a potentially hazardous
situation which, if not avoided may result in minor or moderate
injury. May also alert against unsafe practices.
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 18).
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
ÜDo not modify the ROPS/FOPS unless instructed to do so in installation
instructions. Modifications such as welding, drilling or cutting can weaken
the structure and reduce the protection it provides. A damaged
ROPS/FOPS cannot be repaired — it must be replaced.
ÜTo ensure safe operation, replace damaged or worn-out parts with genuine
Gehl service parts.
ÜGehl skid steer loaders are designed and intended to be used only with Gehl
attachments or approved referral attachments. Gehl cannot be responsible
for operator safety if the loader is used with a non-approved attachment.
ÜRemove all trash and debris from the machine each day, especially in the
engine compartment, to minimize the risk of fire.
ÜAlways face the loader and use the hand holds and steps when getting on
and off the loader. Do not jump off the loader.
ÜNever use starting fluid (ether).
ÜWalk around the machine and warn all nearby personnel before starting the
machine.
ÜAlways perform a daily inspection of the machine before using it. Look for
damage, loose or missing parts, leaks, etc.
