AVOIDING PULL-IN
Pull-in can occur when the bottom of the chain is used for
cutting and is stopped suddenly by hitting a foreign object
or getting pinched. This pulls the chainsaw forwards and
may cause the user to lose control. Pull-in can also occur
when the chain is not running at full speed when contact is
made with the wood and if the bumper spike is not held
securely against the wood being cut.
• Ensure the chain is rotating at full speed and the bumper
spike is correctly positioned when making a cut.
AVOIDING PUSHBACK
Pushback can occur when the top of the chain is used for
cutting and is stopped suddenly by hitting a foreign object
or getting pinched. This pulls the chainsaw towards the
user and may cause the user to lose control.
• Take care not to twist the chainsaw as it is removed
when bucking from underneath the log.
•
Do NOT
cut more than one log at any one time.
• Be aware of situations that may cause the chain to pinch
or pull.
BUMPER SPIKE
This is used to help secure the tree or limb when cutting
and should be used at all times when positioning the
chainsaw. It will help prevent pull-in, pushback, kickback
and loss of control.
