The chuck and exposed metal
surfaces of the tool may become “live” if the tool
drills into wiring in a wall. The operator must
always ensure that the area being drilled dose
not conceal electrical wiring or plumbing.

OPERATING
Never cover air vents. They must always be open for proper
motor cooling.
DRILLING IN WOOD
(Fig 6.)
To prevent ugly splits around the drillhole on the reverse side of
the workpiece, place a scrap piece of timber beneath the material
to be drilled.
DRILLING IN METAL
(Fig 7.)
Metals such as steel, brass, aluminium sheets, stainless steel
and pipe may also be drilled. Mark the point to be drilled with a
nail or a punch before drilling.
DRILLING IN CONCRETE
(Fig 8.)
Rock and masonry are generally drilled in the hammer mode.
When drilling delicate materials such as wall tiles, it is essential
to start with ordinary drilling and once the tile is pierced, to
continue with hammer drilling. In deep boreholes the drill bit
should be pulled out occasionally in order to remove the dust
and chips from the hole.
AUXILIARY HANDLE AND DEPTH STOP
Install the auxiliary handle on the head of the housing and insert
the depth stop in the hole provided. The auxiliary handle can
swivel 360
°
for the most comfortable position and easiest
operation. The depth stop helps keep an accurate depth when
drilling holes.
MAINTENANCE
1. Do not make any adjustments while the motor is in motion.
2. Always disconnect the electric cord from the power source
before mounting the drill bit, changing brushes or lubricating.
3. After use, check your tool to keep it in top condition.
4. Clean out accumulated dust.
5. When the carbon brushes are worn to the standard line, they
must be replaced.
