10. RCD
The use of a residual current device with a rated residual
current of 30mA or less at all times is recommended.
PRACTICAL HANDLING PROCEDURES
1. Pressure
Drilling will NOT be accelerated by placing heavy
pressure on the drill. Such action will only result in a
damaged drill bit, decreased drilling effi ciency, and/or
shortened service life of the drill.
2. Using a large diameter drill bit
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.
3. When drilling completely through the material
When the drill bit bores completely through the
material, careless handing often results in broken drill
bit or damage to the drill body itself due to the sudden
movement of the drill.
Always be alert and ready to release pushing force
when drilling through the material.
4. Switch operation
(1) Trigger switch
By pulling the trigger switch and depressing the
stopper, the switch is held in the ON position for
continuous drilling. To turn the drill OFF, pull the trigger
switch again and release.
(2) Reversing switch
This drill can rotate both clockwise (for drilling)
and counterclockwise (for releasing the drill bit) by
operating the reversing switch.
CAUTION
Never change the direction of rotation while the motor is
rotating. Turn the power switch off before changing the
direction of rotation.
5. Precautions on boring
The drill bit may become overheated during operation;
however, it is suffi ciently operable. Do not cool the drill
bit in water or oil.
6. Caution concerning immediately after use
Immediately after use, while it is still revolving, if
the Drill is placed on a location where considerable
ground chips and dust have accumulated, dust may
occasionally be absorbed into the drill mechanism.
Always pay attention to this undesirable possibility.
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. Inspecting the carbon brushes
The motor employs carbon brushes which are
consumable parts.
When the brushes are worn down, motor trouble may
result. When the brushes are worn down to the limit line,
replace the brushes with new ones. Keep the brushes
clean, so that they smoothly slide into the brush holders.
When replacing the brushes with new ones, be sure to
use a pair of brushes for HiKOKI ELECTRIC DRILL Type
D13 corresponding to the illustrated number. Auto-stop
carbon brushes automatically cut off the electric circuit,
when it is worn down to the wear limit.
This indicates the replacement time of the brush and
prevents damage of the commutator.
4. Replacing carbon brushes
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
5. 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.
6. 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
Repair, modifi cation and inspection of HiKOKI Power
Tools must be carried out by a HiKOKI Authorized
Service Center.
This Parts List will be helpful if presented with the tool to
the HiKOKI Authorized Service Center when requesting
repair or other maintenance.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
MODIFICATION
HiKOKI Power Tools are constantly being improved
and modifi ed to incorporate the latest technological
advancements.
Accordingly, some parts (i.e. code numbers and/or
design) may be changed without prior notice.
