STANDARD ACCESSORIES

○ Chuck wrench (Spec. only for keyed chuck) ................1
Standard accessories are subject to change without notice..

APPLICATIONS

○ Boring holes in metal, wood and plastic.

PRIOR TO OPERATION

1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specifi ed on the product
nameplate.
2. Power switch
Ensure that the power switch is in the OFF position. If the
plug is connected to a receptacle while the power switch
is in the ON position, the power tool will start operating
immediately, inviting serious accident.
3. Extension cord
When the work area is removed from the power source.
Use an extension cord of suffi cient thickness and rated
capacity. The extension cord should be kept as short as
practicable.
4. Selecting the appropriate drill bit:
○ When boring metal or plastic
Use ordinary metalworking drill bits.
○ When boring wood
Use ordinary woodworking drill bits.
However, when drilling 6.5 mm or smaller holes, use a
metalworking drill bit.
5. Mounting and dismounting of the bit
For keyed chuck (Fig. 1)
(1) Open the chuck jaws, and insert the bit into the chuck.
(2) Place the chuck wrench in each of the three holes in the
chuck, and turn it in the clockwise direction (viewed from
the front side). Tighten securely.
(3) To remove the bit, place the chuck wrench into one of
the holes in the chuck and turn it in the counterclockwise
direction.
For keyless chuck (Fig. 2)
(1) Open the chuck jaws, and insert the bit into the chuck.
To open the chuck jaws, hold the ring while turning the
sleeve in the counterclockwise direction (viewed from the
front side).
(2) Firmly grasp the ring and turn the sleeve in the clockwise
direction. Tighten securely.
(3) To remove the bit, fi rmly grasp the ring and turn the
sleeve in the counterclockwise direction.
(4) If it is hard to loosen the sleeve, fi x the spindle using the
open-end wrench, hold the sleeve fi rmly, and turn it in the
loosening direction (counterclockwise when viewed from
the front). (Fig. 3)
6. Check the rotational direction (Fig. 4)
The bit rotates clockwise (viewed from the rear side) by
turning the rotational change lever to R-mark.
The rotational change lever is returned to the L-mark to
turn the bit counterclockwise.
(The and marks are provided on the body.)
7. RCD
The use of a residual current device with a rated residual
current of 30 mA or less at all times is recommended.

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.
○ 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. (Fig. 5)
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 defl 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 off 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, 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 effi 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 a HiKOKI AUTHORIZED
SERVICE CENTER.
5. Replacing supply cord
If the replacement of the supply cord is necessary, it has
to be done by HiKOKI Authorized Service Center to avoid
a safety hazard.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
