CAUTION! The chain brake level should not be
used for starting and stopping the saw during normal
operation.
Kickback is the sudden backward/upward motion of the
chain saw, occurring when the chain (at the tip of the chain
bar) comes in contact with a log or wood, or when the chain
becomes jammed.
When kickback occurs the chain saw reacts unpredictably
and can cause severe injuries to the operator or bystanders.
Particular attention must be given when sawing sideward,
slanted or during length cuts, as the spiked bumper usually
can not be applied.
To avoid kickback:
- Saw with guide bar at a flat angle:
- Never work with a loose, widely stretched or the heavily
worn out chain:
- Ensure chain is sharpened correctly:
- Never saw above shoulder height:
- Never work with the tip of the guide bar:
- Always hold the chain saw firmly with both hands:
- Always use a low kickback chain:
- Apply the metal gripping teeth for leverage:
- Ensure correct chain tension:
