Pull-in
WARNING
■ Pull-in occurs when the chain on the bottom of the bar is
suddenly stopped or significantly slowed when it is
pinched, caught or encounters a foreign object in the
wood. The reaction of the chain pulls the garden pruner
forward and may cause the operator to lose control,
which, in turn, may cause serious or fatal injury.
■ Pull-in usually occurs when the bumper of the garden
pruner is not held securely against the branch or limb and
the chain is not rotating at full speed before it contacts the
wood.
■ To reduce the risk of pull-in:
– Cut with a sharp, properly tensioned chain.
– Always start a cut with the chain rotating at full speed
and with the bumper in contact with the wood.
– Use caution when cutting small-size brush,
branches and saplings which may easily catch the
chain, spring towards you or pull you off balance.
– Do not use the garden pruner with a damaged or
missing guard.
