10 Maintenance, Repair and Storage

10.1 Warnings and Instructions

WARNING
￭ There are no user-authorized repairs for the battery or
pole pruner. To reduce the risk of fire, electric shock or
other personal injury and property damage:
– Users may carry out only the cleaning and
maintenance operations described in this manual.
– Strictly follow the cleaning and maintenance
instructions in the appropriate sections of this
instruction manual.
– STIHL recommends that all repair work be
performed by authorized STIHL servicing dealers.
￭ Unintentional starting may result in personal injury or
property damage. To reduce the risk of personal injury
and property damage from unintentional starting:
– Remove the battery before inspecting
the pole pruner or carrying out any
cleaning, maintenance or repair work,
before storing, and any other time it is
not in use.
￭ The bar and chain are the only user-serviceable parts of
the pole pruner. Proper maintenance will help maintain
cutting performance and reduce the risk of personal injury
caused by chain derailment and reactive forces.
– Wear gloves when handling the saw chain.
– Keep the chain, guide bar and sprocket clean.
– Replace the chain and guide bar when they become
worn or damaged.
– Keep the chain sharp and at proper tension.
– Tighten all nuts, bolts and screws after each use.
￭ Return the pole pruner 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 pole pruner and battery, and an increased risk of
fire, electric shock and other personal injury or property
damage.
– Remove the battery from the pole pruner before
storing.
– Never store the pole pruner or charger with the
battery inserted.
– Store the pole pruner and battery indoors in a dry,
secure place that cannot be accessed by children or
other unauthorized users.
– Never store the battery in the pole pruner, in the
charger, in a metal container or in a container with
metal objects (e.g., paper clips, nails, coins, keys).
NOTICE
Always release tension on the chain after finishing work. The
chain contracts as it cools down. If it is not slackened, it can
damage the drive shaft and bearings. Properly re-tension
the chain before using the pole pruner again.
