The machine is used for four functions: drill, hammer,
hammer drill, chisel, vari-lock and rotation stop．
Hammer drilling mode can destroy the structure of the
machine when used for fastening or drilling without SDS
Plus bits.
Use bits only with hard metal and SDS Plus shaft only.
When hammer drilling, do not apply too much pressure.

DRILL

1. Examine the direction of rotation selector for the correct
setting (forward or reverse).
2. Attach the material to be drilled in a vise or with clamps
to keep it from turning.
3. Hold the drill tightly and put the bit at the correct
poiistion.
4. Push the switch trigger to start the drill.
5. Move the drill bit into the workpiece and apply only
sufficient pressure to keep the bit cutting. Do not force
the drill or apply side pressure to elongate a hole.
6. When drilling on hard or smooth surfaces, use a center
punch to identify the necessary hole location. This can
prevent the drill bit from moving from the center.
7. When drilling metals, use a light oil on the drill bit to
keep it from overheating. The oil can prolong the life of
the bit and increase the drilling action.
8. If the bit jams in the workpiece or if the drill stalls, stop
the machine immediately. Remove the bit from the
workpiece and determine the reason for jamming.
Dill 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 of
control can result in possible serious injury.
