WARNING
■ The risk of kickback is increased if you use the
chainsaw with one hand. If kickback occurs,
the saw may be thrown up in the direction of
the operator. The operator can lose control of
the saw and be seriously or fatally injured.
► Do not cut with the upper quadrant of the
bar nose.
► Never support yourself on the limb being
cut.
► Never attempt to hold falling limbs.
The saw may be used with one hand if the fol‐
lowing conditions apply:
– Two-handed cutting is not possible.
– The working position means that one hand is
required for support during the cut.
– The saw can be held firmly with one hand.
– All parts of your body are clear of the cutting
attachment.
