OPERATION
VARIABLE SPEED (Fig.4)
Your drill has a variable speed control
mechanism designad to allow the operator
to have control and adjustment of speed and
torque limits. The speed and torque of your drill
can be increased or decreased by rotating the
variable speed control button. lt is advisable to
start the drill at low speed so that the drill does
not move from the intended centre.
HAMMER MECHANISM (Fig.5)
The hammer mechanism can be operated with
the machine running. When drilling materials
that are liable to break, such as tiles, it is
advisable to start the drill without impact. For
deep holes, frequently remove the tool to
exhaust chips from the hole. To drill with impact,
only use drill bits with a carbide tip and negative
cut angle on the lip. Carbide tip dill bits should
only be sharpened with silicone carbide wheeis.
To work WITHOUT HAMMER, as a normal drill,
turn the lever to the point where a drill is printed.
To work WITH HAMMER, push the lever to the
position where a hammer icon is printed.
WARNING:
The chuck and exposed metal surtaces of the tool may become `live´ if the
tool drills, in to wiring in a wall. The operator must always ensure that the area
being drilled does not conceal electrical wiring or plumbing.
