Your shindaiwa chain saw is designed to provide
many hours of trouble free service. Regular
scheduled maintenance will help your chain saw
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 ask your shindaiwa
Dealer for repairs.
Skill Levels
Level 1 = Easy to do. Common tools may be
required.
Level 2 = Moderate difficulty. Some specialized
tools may be required.
