When ddlling hard smooth surfaces use acenter punch

to mark desired hole location. This will prevent the drill

bitfrom slipping off center as the holeis started. How-

ever, the low speed feature allows starting holes without

center punching if desired. Toaccomplish this, simply

operate yourdrill ata lowspeed untilthe hole is started.

The material tobe drilled should be secured in a vise or

with clamps to keep it from turning as the drill bit rotates.

Hold tool firmly and place the bit at the point to be drilled.

Depress the switchtrigger to start toot.

Move the drill bit into the workpiece applying only

enough pressure to keep the bitcutting. Donot force or

apply side pressure to elongate a hole.

,_ WARNING: Be prepared for binding or bit

breakthrough. When these situations occur, drill

has a tendency to grab and kick opposite to the

direction of rotation and could cause loss of

control when breaking through material. If not

prepared, this loss ofcontrol can result in

possible serious injury.

When drilling metals, use a light oil on the drill bit to

keep itfrom overheating. The oil will prolong the life of

the bit and increase the drilling action.

If the bit jams in workpiece or if the drill stalls, release

switch trigger immediately. Remove the bit from the

workpiece and determine the reason for jamming.
