ON position. To turn it OFF, slide the on/off switch to the
OFF position.
OPERATING THE POWER CARVER
See Figures 5 - 6, page 10.
Learning to use the power carver:
 Hold the tool in your hand and get used to its weight,
balance, and the taper of the housing. This taper permits
the tool to be grasped like a pencil or in a "golf grip"
method.
 Examine the power carver accessories carefully. Damaged
accessories can fly apart as they come up to speed and
should not be used. The use of damaged accessories
can result in serious personal injury.
 Practice on scrap materials first to see how the tool
operates. Keep in mind that the work is done by the speed
of the tool and by the accessory in the collet. You should
not lean on or push the tool into the work.
