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
䡬
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 efficiency,
but may also damage the drill tip.
䡬
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.
HOW TO USE
1. Switch operation
䡬
When the trigger is depressed, the tool rotates. When
the trigger is released, the tool stops.
䡬
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.
䡬
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. 7
)
䡬
Pulling the trigger and pushing the stopper, it keeps
the switched-on condition which is convenient for
continuous running. When switching off, the stopper
can be disconnected by pulling the trigger again.
2. Drilling
䡬
When drilling, start the drill slowly, and gradually
increasing speed as you drill.
䡬
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 deflect the bit.
䡬
To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the
last part of the hole.
䡬
If the drill stalls, release the trigger immediately,
remove the bit from the work and start again. Do not
click the trigger on and off in an attempt to start a
stalled drill. This can damage the drill.
䡬
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 firm 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 efficiency, 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.
