WARNING:
• Never attempt to enlarge a hole with the cut-
ter 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 perpen-
dicular position when cutting the first hole.
Lap joints up to 130 mm (5-1/8") can be cut with this
tool.
NOTE:
• Lap joints can be cut only on the front (side
away from you) of the workpiece.

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspec-
tion or maintenance.
