h) Keep handles and grasping surfaces dry, clean
and free from oil and grease.
Slippery handles and grasping surfaces do not
allow for safe handling and control of the tool in
unexpected situations.
5) Service
a) Have your power tool serviced by a qualifi ed
repair person using only identical replacement
parts.
This will ensure that the safety of the power tool is
maintained.
PRECAUTION
Keep children and infi rm persons away.
When not in use, tools should be stored out of reach of
children and infi rm persons.
DRILL SAFETY WARNINGS
Safety instructions for all operations
a) Use the auxiliary handle(s).
Loss of control can cause personal injury.
b) Hold the power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring or its own cord.
Cutting accessory contacting a "live" wire may make
exposed metal parts of the power tool "live" and could
give the operator an electric shock.
Safety instructions when using long drill bits
a) Never operate at higher speed than the maximum
speed rating of the drill bit.
At higher speeds, the bit is likely to bend if allowed to
rotate freely without contacting the workpiece, resulting
in personal injury.
b) Always start drilling at low speed and with the bit tip
in contact with the workpiece.
At higher speeds, the bit is likely to bend if allowed to
rotate freely without contacting the workpiece, resulting
in personal injury.
c) Apply pressure only in direct line with the bit and do
not apply excessive pressure.
Bits can bend causing breakage or loss of control,
resulting in personal injury.
ADDITIONAL SAFETY WARNINGS
1. Make sure to securely hold the tool during operation.
Failure to do so can result in accidents or injuries.
(Fig. 15)
2. Ensure that the power source to be utilized conforms
to the power requirements specifi ed on the product
nameplate.
3. 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, which could cause a serious
accident.
4. 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.
5. Hold the drill and side handle securely with both hands
when using.
6. Do not wear gloves made of stuff liable to roll up such as
cotton, wool, cloth or string, etc.
7. Prior to drilling into walls, ceilings or fl oors, ensure there
are no electric cables or conduits inside.
8. 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,
use side handle, hold the drill tightly with both hands,
and ensure that the drill is vertical to the material being
drilled.
○ 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.
○ 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.
9. Attaching the angle unit. (Optional accessory for D13VF
and D13VG)
(1) Removing chuck from drill (Fig. 10)
○ If the chuck cannot be removed by striking the wrench,
don't strike the wrench forcibly and send the drill to a
HiKOKI AUTHORIZED SERVICE CENTER.
(2) Removing chuck from angle unit (Fig. 12)
○ The chuck can be removed from angle unit in the same
manner it was removed from the drill; however, ALWAYS
REMOVE ANGLE UNIT FROM THE DRILL BEFORE
ATTEMPTING TO LOOSEN CHUCK. This will prevent
damage of drills gear. Use open end wrench provided to
hold angle unit spindle before attempting to loosen chuck.
○ If the chuck cannot be removed by striking the wrench,
don't strike the wrench forcibly and send the drill to a
HiKOKI AUTHORIZED SERVICE CENTER.
10. When the power tool is used with a hook fi xed to it, pay
attention to the following points:
○ Before hanging the main unit from the waist belt, make
sure that the drill has come to a complete stop.
While it is suspended from the waist belt, the power plug
must be disconnected from the power source.
○ Do not walk about with the power tool hanging from the
waist belt.
○ In the case of operation in a high place, it is dangerous
to drop the tool accidentally. If the hook is deformed or
hung from the wrong position, there is danger that the
hook will slip off and the tool will fall.
Be careful to avoid danger.
○ In making a through hole, the power tool sometimes
shakes violently when the workpiece is pierced, from
example. Be careful you are not hurt by the hook even if
such situation happens.
