MAINTENANCE
Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects
away from all openings. Always stop engine, disconnect spark plug, and make sure all moving parts
have come to a complete stop before removing obstructions, clearing debris, or servicing unit.
Allow unit to cool before performing service. Wear gloves to protect hands from sharp edges and
hot surfaces.
Your SHINDAIWA unit is designed to provide many hours of trouble free service. Regular scheduled maintenance
will help your unit achieve that goal. If you are unsure or are not equipped with the necessary tools, you may want
to take your unit to an SHINDAIWA Service Dealer for maintenance. To help you decide whether you want to
DO-IT-YOURSELF or have the SHINDAIWA Dealer do it, each maintenance task has been graded. If the task is
not listed, see your SHINDAIWA Dealer for repairs.
