c) If necessary, use a handsaw or second chain saw to release the trapped
saw by cutting a minimum of 30 cm away from the trapped saw.
Whether a handsaw or a chain-saw is used to free a trapped saw, the
release cuts should always be outboard (toward the tips of the branch), in
order to prevent the saw being taken with the section and further
complicating the situation.
Using a mechanical basket (where possible) is still the safest solution to
ensure the optimal operation of the chain saw (see fig.38).
