mounted into the end of the collet.
4. Rotate the collet nut while depressing
the collet lock to secure the bit. Only
tighten 1/3 of a turn with the collet
wrench.
Low RPM Uses
Low RPM's are best for grinding and cut-
ting materials that have low melting points.
Plastics in particular often melt from the
heat generated by high speed bits. Low
RPM's are also best for polishing and buff-
ing with the felt accessories included.
Failure to wear safety glasses while
operating the grinder could cause
serious personal eye injury.
Use low RPM settings when work-
ing with plastics or other materi-
als with low melting points. Melted
plastics can liquefy, be thrown into
the air, and stick to the operator,
causing serious personal injury.
Using The Grinder
The Model H6156 is best suited for high
RPM, low torque applications.
Always test the bit and RPM combination
on a scrap piece of material similar to the
workpiece. Trial and error is the best way
to determine the ideal setup.
To use the grinder:
1. Grasp the grinder with a secure grip.
2. Rotate the speed lever to turn ON the
mini grinder.
3. Adjust the speed lever to change the
RPM.
4. Firmly grasp the grinder and ease it
against the workpiece using light pres-
sure.
