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.

IMPACT DRILL SAFETY WARNINGS

Safety instructions for all operations

a) Wear ear protectors when impact drilling.

Exposure to noise can cause hearing loss.

b) Use the auxiliary handle(s).

Loss of control can cause personal injury.

c) 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. 12).

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. Drilling

○ When drilling, start the impact drill slowly, and gradually

increasing speed as you impact 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 impact 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

impact drill. This can damage the impact drill.

○ The larger the drill bit diameter, the larger the reactive

force on your arm.

Be careful not to lose control of the impact drill because

of this reactive force.

To maintain ﬁ rm control, establish a good foothold, use

side handle, hold the impact drill tightly with both hands,

and ensure that the impact 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

impact 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.

6. Check the rotational direction

○ Actuate the rotational change lever only when the

machine is at a standstill.

The rotational change lever is used to reverse the

rotational direction of the machine.

However, this is not possible with the On/Oﬀ switch

actuated.

○ Operating the tool with the rotational change lever in

mid-position may result in damage.

When switching, make sure that you shift the rotational

change lever to the correct position.

○ Always use the impact drill with clockwise rotation, when

using it as an impact drill.

7. IMPACT to ROTATION changeover

○ Do not use the impact drill in the IMPACT mode if the

material can be bored by rotation only. Such action will

not only reduce drill eﬃ 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.

8. RCD

The use of a residual current device with a rated residual

current of 30 mA or less at all times is recommended.
