NOTE:
A hole a little longer than predetermined may be

WARNING:
Never attempt to enlarge a hole with the cutter
•
chain still within the hole. This will cause
unstable and dangerous operation.
Never angle the cutter chain when cutting the first
•
hole, or a dangerous kickback may result. Always
have the cutter chain set to the perpendicular
position when cutting the first hole.
Lap joints up to 130 mm can be cut with this tool.
