The tool holder
without the need for a chuck key.
Pull collar
back. Insert the bit. It may be necessary to
rotate the bit to ensure it engages correctly. Release the
collar to lock the bit in place. Check by pulling the bit to
see if it's firmly seated.
IMPORTANT: Always clean and lightly grease the tool
shaft before inserting into the chuck.
Take care that the dust protection cap is not damaged.
Allowing dust and debris inside the holder will cause
problems in the future.
To remove a bit, slide the collar
out the tool.
WARNING: Bit will be hot after use.
9.7 DUST AND SWARF:
A correctly fitted dusk mask, suitable for the activity and
in accordance to the relevant standard, must be worn.
For work activities involving exposure to fine wood dust,
a mask rated to at least FFP2 should be used.
Swarf produced by metal drilling is extremely sharp. Take
precautions when clearing swarf. The burr left on the
hole is also sharp and should be removed with a suitable
tool.
9.8 DRILLING WOOD AND PLASTIC
(Pneumatic SDS Hammer disengaged)
To prevent splitting around the drill holes on the reverse
side, place a piece of scrap timber under the material to
be drilled.
9.9 DRILLING METAL
(Pneumatic SDS Hammer disengaged)
Metals such as sheet steel, aluminium and brass may be
drilled. Mark the point to be drilled with a centre punch
to help the drill bit tip to locate. A drop of oil on area will
aid cutting and help prolong the life of the bit.
