Chuck Cleaning:
Once disassembled, clean all parts with a type of
oil-less solvent such as Automotive Break Cleaner.
Chuck Re-assembly:
Reassemble in reverse order.
Point Split Tube Cavity:
Routinely vacuum and using a dry cloth, wipe out
the inside of the Point Split Tube. Removing
grinding dust will help produce consistent split
point drills by retaining the ID dimensions of the
tube and reducing early wear.
Sharpening Tube Cavity:
Using a dry cloth, wipe out the inside of the brass
tube, removing grinding dust. Over time it may be
necessary to replace the sharpening tube. The
sharpening tube is threaded into the housing
using right-handed threads. To remove, rotate
tube counterclockwise using a spanner wrench.
Replace as needed.
Wheel Housing Cavity:
While grinding wheel is out of machine and before
replacing wheel, vacuum out wheel housing and
wipe around the hub area.
External Machine Castings:
Wipe down external machine castings with a
mild household cleaner.
Grit Tray/Vacuum Port Connection:
Grit tray
At the back of the
machine, located
underneath the
grinding motor is the
grit tray. Drill grindings
will accumulate inside
the grit tray. The grit
tray has a magnetic
liner to attract and hold
these dust particles. Do
not let the tray become more than 1/3 full. To
remove tray, unscrew brass thumb screw.
Remove tray and dump contents. Wipe excess
dust from the tray with a rag.
Vacuum Port Connector (Optional)
The grit tray has
a knock out plug
that can be
removed by hand
and replaced with
the vacuum tube
(SA16030TA).
Use this port to
connect a vacuum
hose to the
XT3000. This method of extracting dust
particles from the machine will keep it cleaner
and is recommended.
Oil Lubrication:
Never use an oil-based lubricant on any part
of this machine! Oil-based lubricant will collect
grinding dust particles. Powdered graphite
may be applied to any sliding parts located on
the machine.
