8. IMPACT to ROTATION changeover (Fig. 6)
Shift the change lever between the right and left
positions to switch easily between IMPACT (rotation and
impact) and ROTATION (rotation only), respectively.
To bore holes in hard materials such as concrete,
stone and tiles, shift the change lever to the right-hand
position (as indicated by the mark).
The drill bit operates by the combined actions of impact
and rotation.
To bore holes in metal, wood and plastic, shift the
change lever to the left-hand position (as indicated by
the mark). The drill bit operates by rotational action
only, as in the case of a conventional electric drill.
CAUTION
○ Do not use the Impact Drill in the IMPACT function
if the material can be bored by rotation only. Such
action will not only reduce drill e ffi ciency, but may
also damage the drill tip.
○ Operating the Impact Drill with the change lever
in mid-position may result in damage. When
switching, make sure that you shift the change lever
to the correct position.
9. High-speed/Low-speed changeover:
Prior to changing speed, ensure that the switch is in the
OFF position, and the drill has come to a complete stop.
To change speed, rotate the gear shift dial as indicated
by the arrow in Fig. 7 . The numeral “1” engraved on the
drill body denotes low speed, the numeral “2” denotes
high speed.
If it is hard to turn the gear shift dial, turn the chuck
slightly in either direction and then turn the gear shift
dial again.
HOW TO USE
1. Switch operation
○ When the trigger is depressed, the tool rotates. When
the trigger is released, the tool stops.
○ The rotational speed of the drill can be controlled by
varying the amount that the trigger switch is pulled.
Speed is low when the trigger switch is pulled slightly
and increases as the trigger switch is pulled more.
○ The desired rotation speed can be pre-selected with
the speed control dial.
Turn the speed control dial clockwise for higher speed
and counterclockwise for lower speed. ( Fig. 8 )
○ Pulling the trigger and pushing the stopper, it keeps
the switched-on condition which is convenient for
continuous running. When switching o ff , the stopper
can be disconnected by pulling the trigger again.
CAUTION
If the L-side of push button is pressed for reverse bit
rotation, the stopper cannot be used.
2. Drilling
○ When drilling, start the drill slowly, and gradually
increasing speed as you drill.
○ Always apply pressure in a straight line with the bit. Use
enough pressure to keep drilling, but do not push hard
enough to stall the motor or de fl ect the bit.
○ To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the
last part of the hole.
○ If the drill stalls, release the trigger immediately, remove
the bit from the work and start again. Do not click the
trigger on and o ff in an attempt to start a stalled drill.
This can damage the drill.
○ The larger the drill bit diameter, the larger the reactive
force on your arm.
Be careful not to lose control of the drill because of this
reactive force.
To maintain fi rm control, establish a good foothold,
use side handle, hold the drill tightly with both hands,
and ensure that the drill is vertical to the material being
drilled.
MAINTENANCE AND INSPECTION
1. Inspecting the drill bits
Since use of an abraded drill bits will cause motor
malfunctioning and degraded e ffi ciency, replace the
drill bits with a new one or resharpening without delay
when abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws
be loose, retighten them immediately. Failure to do so
could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very “heart” of the power
tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
4. Inspecting the carbon brushes
For your continued safety and electrical shock
protection, carbon brush inspection and replacement
on this tool should ONLY be performed by an Authorized
Service Center.
5. Replacing supply cord
If the supply cord of Tool is damaged, the Tool must be
returned to Authorized Service Center for the cord to be
replaced.
