manual provides recommendations for safe and efficient approaches to problem situations.
If an operating problem should arise, turn to the TROUBLESHOOTING GUIDES and attempt to isolate what is
causing the malfunction. The GUIDES are listed by symptoms and follow with suggestions as to the most probable
cause of the problem.
Once you have pinpointed the source of the problem, turn to the appropriate "How To..." section and review the
proper procedures for removing, replacing or adjusting a part. The "How To..." sections are organized by
replaceable part (or assembly) name and each page lists the “Special Tools Required“ to complete the specific
task.
Refer to COMPONENT IDENTIFICATION in the front part of this section to locate and identify in order service
repair parts for your machine.

SPECIAL SERVICE TOOL REQUIREMENTS
Unless otherwise specified, only basic hand tools are required to perform service procedures
outlined in this section. Some of these standard tools should consist of: Philips and Straight-
Blade Screw Drivers, Torx Set, Pliers, Rubber Mallet, Pry Bar, Snap Ring Pliers (internal and
external), Standard and Metric size Socket Set (3/8 or 1/2 drive), and Standard and Metric size
Combination, open-end, or Box Wrenches.
Specialized tools will be listed after the sub-heading Special Service Tools:, which appears
below the Service Procedure Heading at the top of the page. If no specialized tools are
