SPRINGPOLES
See Fig.22.
A springpole is any log, branch, rooted stump, or sapling
which is bent under tension by other wood so that it springs
back if the wood holding it is cut or removed. On a fallen
tree, a rooted stump has a high potential of springing back
to the upright position during the bucking cut to separate
the log from the stump. Watch out for springpoles, they are
dangerous.
WARNING
Springpoles are dangerous and could strike the operator,
causing the operator to lose control of the chainsaw.
This could result in severe or fatal injury to the operator.
WARNING
To avoid serious personal injury, always remove
the battery pack from the product when cleaning or

with hearing and head protection. Failure to do so could
result in objects being thrown into your eyes resulting in
possible serious injury.

commercial solvents and may be damaged by their use.

Do not at any time let brake fl uids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which could result in serious personal
injury.
REPLACING BAR AND CHAIN

Remove the battery pack from the chainsaw and make
sure the chain has stopped before you do any work on
the saw. Failure to do so may result in accidental starting
and possible serious injury.

To avoid serious personal injury, read and understand all
the safety instructions in this section.
Never touch or adjust the chain while the motor is
running. The saw chain is very sharp; always wear
protective gloves when performing maintenance to the
chain to avoid possible serious lacerations.
