Causes and operator prevention
of pull-in (Fig. 5):
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 saw forward
and may cause the operator to lose control,
which, in turn, may cause serious or fatal
injury.
Pull-in usually occurs when the bucking
•
spikes of the saw are not held securely
against the branch or limb and the chain is not rotating at full speed before it contacts the
wood.
