￭ Like an automobile brake, the chain brake on your chain
saw incurs wear each time it is engaged. In order for the
chain brake on your STIHL chain saw to properly perform
its function of reducing the risk of kickback and other
injuries, it must be properly maintained. For the proper
and effective operation of the chain brake, return the chain
saw to your STIHL servicing dealer for periodic inspection
and servicing of the brake system according to the
following schedule:
– Heavy Usage: every 3 months
– Moderate Usage: every 6 months
– Occasional Usage: every 12 months
￭ Return the chain saw immediately for maintenance
whenever the brake system cannot be thoroughly cleaned
or there is a change in its operating characteristics.
￭ Use of parts that are not authorized or approved by STIHL
may cause serious or fatal injury or property damage.
– STIHL recommends that only identical authorized
STIHL replacement parts be used for repair or
maintenance.
￭ To reduce the risk of electric shock:
– Unplug the charger from the electrical outlet before
inspecting or cleaning the charger.
– Regularly check the charger and ensure that the
insulation of the power cord and plug are in good
condition and show no signs of aging (brittleness),
wear or damage.
– Replace the charger if the power supply cord
becomes worn or damaged. The power supply cord
cannot be repaired or replaced.
￭ To reduce the risk of short circuit and fire:
– Keep the battery guides free of foreign matter. Clean
as necessary with a dry cloth or soft, dry brush.
￭ Improper storage can result in unauthorized use, damage
to the chain saw, battery and charger, and an increased
risk of fire, electric shock and other personal injury or
property damage.
– Engage the chain brake by moving the front hand
guard forward to and remove the battery from the
chain saw before storing.
– Never store the chain saw and charger with the
battery inserted.
– Before storing, always unplug the charger from the
electrical outlet and remove the battery.
– Store the chain saw, battery and charger indoors in
a dry, secure place that cannot be accessed by
children or other unauthorized users.
– Never store the battery in the chain saw, in the
charger, in a metal container or in a container with
metal objects (e.g., paper clips, nails, coins, keys).
