D4777 ½" Router Collet Extension Instructions
Serious cuts, amputation, entanglement, or
death can occur from contact with spinning
router bit. Improperly secured bits or spindle
parts/fasteners can fly off and strike nearby
operators or bystanders with great force. Flying dust or debris from cutting operation can
cause eye injuries or blindness. To minimize
risk of getting hurt or killed, anyone operating router MUST completely heed all hazards
and warnings in this instruction manual.
Extending router bits increases the strain
on the bit and the collet. It is important
that you verify the bit is securely installed
in the collet before using the router, or
serious personal injury could result from
the router bit or flying debris. When using
an extended router bit, decrease the cutting depth and make additional passes on
the workpiece.
