5. Push the drill bit up through chisel,
and into the opened jaws of the
chuck as far as it will go, then
back off approx. 1/16”(2mm).
6. Secure the drill bit in this position,
by tightening the jaws using the
chuck key provided.
Note:
It is important that the drill bit bottoms out on the CHISEL and NOT the chuck,
before setting the 1/16” (2mm) clearance.
IIf the bit does bottom out in the chuck first, slacken off the grub screw securing
the chisel and lower it approx. 1/16” (2mm) and try again.
• Alternatively, grind off a portion of the drill shank.
This adjustment is IMPORTANT to ensure a proper clearance is provided
between the cutting tips of the bit and the points of the chisel.
For certain types of wood, it may be necessary to increase this distance up to
a maximum of 3/16" (5mm). This will become obvious when cutting
commences and chips are not being ejected satisfactorily.
