11 Before Starting Work

￭ 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 function properly,
it must be properly maintained. 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 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 STIHL
replacement parts be used for repair or
maintenance.
￭ 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 and battery, 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
chain saw before storing.
– Never store the chain saw or charger with the battery
inserted.
– Store the chain saw and battery 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).
