When enlarging a hole both transversely and longitudinally, cut the holes in the
006012
order indicated from No.(1) to (6) as shown. This makes for more easy and
1
efficient hole enlargement.
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.
006013
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 inspection or maintenance.
