SAFETY

Introduction
Safety is the most important element of any repair
procedure. Knowledge of the procedure to be performed
and safe work habits are essential to preventing death,
personal injury, or property damage. Use the following
statements as a common-sense guide to proper work
and tool-use habits.
Prepare for the Job
Preparation is essential to complete a procedure in a
safe and efficient manner.
• Wear proper clothing. Loose or baggy clothing could
become tangled in moving parts.
• Use eye/face protection. Always use proper eye/face
protection to protect your eyes from flying debris or
chemical splatters.
• Wear protective footwear. Wear safety shoes
(steel-toe) to protect your feet from falling objects.
• Use gloves when handling parts. Parts may have
sharp edges or may be hot.
• Remove jewelry prior to servicing electrical systems.
• Prepare proper tools and equipment. Always use the
correct tool for the job. Improper or homemade tools
can cause injury or machine damage.
• Prepare needed parts and materials. Gather the
needed parts and materials before beginning the
procedure.
• Allow machine to cool. Many components can get hot
during operation. Be sure to allow enough time for
components to cool before beginning service.
• Prepare proper work-space lighting. A well-lit work
area can make the job easier.
• Follow procedures and safety warnings. Service
procedures are written to be as safe and efficient as
possible. Never take shortcuts.
• Be prepared for emergencies. Accidents can happen,
even under the best conditions. Fire extinguishers
and first aid kits should be well maintained and easily
accessible.
