NOTE: Mark "1"is Low speed position, mark "2" is High speed position that moulding
onto the button of two speed selector .
• The drill has a two-speed gear train designed for drilling at 1 (LOW) or 2 (HIGH) speed. A
gear selector is located on top of the drill to select either low or high speed. When you
push the button forward and select low speed range, the speed will decrease but will
provide more power and torque. When using drill in the high speed range. Speed will
increase but will provide less power and torque. Use low speed for high power and
torque application and high speed for fast drilling applications.
Important: NEVER adjust this two speed selector whilst the drill is running. Always let it
come to a complete stop first.

LED Light

The LED work-light ( J in the functional description) can light prior to motor running if you
press the switch lightly, which keep the work area to be lighted for checking clearly at first,
and it lights also during your operation.
WARNING:
Do not stare directly at the light beam. Never aim the beam at any person or an object
other than the work piece.
Do not deliberately aim the beam at personnel and ensure that it is not directed towards
the eye of a person for longer than 0.25s.
Installing And Removing A Bit And A Drill
Center the rotation direction knob to prevent the motor accidentally starting.
To insert a drill bit or other accessory:
• Grasp the rear half of the chuck (A) with one hand and use your other hand to rotate the
front half in the counterclockwise direction, as viewed from the chuck end.
• Insert the bit or other accessory fully into the chuck, and tighten securely by holding the
rear half of the chuck and rotating the front portion in the clockwise direction as viewed
from the chuck end.
WARNING: Never attempt to tighten drill bits or any other accessory by holding the front
part of the chuck and turning the tool on - damage and/or personal injury can result.

Drilling
• Only use sharp drill bits.
• Secure work properly; do not try to hold object by hand. (Refer to Safety Instructions)
• Be sure to wear appropriate, required safety equipment. (Refer to Safety Instructions)
• Make sure work area is safe and secure. (Refer to Safety Instructions)
• Start drilling slowly, using light pressure to start the hole and prevent the bit from
slipping out of it.
• Drill in a straight line, applying enough pressure to keep the bit biting, but not too
much to stall the motor or deflect the bit.
• HOLD THE DRILL FIRMLY WITH TWO HANDS TO CONTROL THE TWISTING ACTION.
can damage the drill.
• Minimize stalling upon breakthrough by reducing applied pressure and reducing speed
through the last part of the hole.
• Once the hole is drilled, keep the motor running as you pull the drill bit out of the hole
to reduce jamming.
• When drilling metals (except for cast iron and brass) use a cutting lubricant such as
sulphurized cutting oil or lard oil. Note: cast iron and brass should be drilled dry.
• Drilling wood builds up chips in the flutes of twist drill bits. Frequently pull the bit out
of the wood and clear the woods chips from the bit flutes during use.
- Drilling in wood
• Holes in wood can use the same twist drill bits that you would use for metal (or spade
bits). Make sure the bits are sharp and frequently stop to clear the wood particles from
the flutes.
- Drilling in metal
• When drilling metals (except for cast iron and brass) use a cutting lubricant such as
sulphurized cutting oil or lard oil. Note: cast iron and brass should be drilled dry.
- Drilling in masonry
• Use carbide tipped masonry bits {refer to Drilling Section). Drill evenly keeping a
uniform force on the drill, but not too much or you can crack the brittle material. If you
are experiencing a smooth, even flow of dust, that indicates a good drilling rate.
