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.)

CAUTION

Always use the impact drill with clockwise rotation,

when using it as an impact drill.

7. Fixing the side handle (Fig. 5)

Attach the side handle to the mounting part.

Rotate the side handle grip in a clockwise direction to

secure it.

Set the side handle to a position that is suited to the

operation and then securely tighten the side handle

grip.

To attach a depth gauge on the side handle, insert the

gauge into the U-shaped groove on the side handle,

adjust the position of the depth gauge in accordance

with the desired depth of the hole, and ﬁ rmly tighten the

side handle grip. (Fig. 6)

8. IMPACT to ROTATION changeover (Fig. 7)

Shift the change lever between the right and left

positions to switch easily between IMPACT (rotation and

impact) and ROTATION (rotation only), respectively.

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

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

○ 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 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.

HOW TO USE

1. Switch operation (Fig. 8)

○ When the trigger is depressed, the tool rotates. When

the trigger is released, the tool stops.

○ 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.

○ 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.

2. When using as a Drill or an Impact Drill

(1) Pressing force of the drill

You cannot drill holes more quickly even if you press

the drill with a stronger force than necessary. It not only

damages tip of drill bit and decreases the eﬃ ciency of

operation, but also shortens the life of the drill tip.

(2) In case of penetrating holes

Drill bits can be broken when the material being drilled

is penetrated. It is important to decrease pressing force

just before penetrating.

mark).

CAUTION

In continuous operation, conduct no-load operation for

ﬁ ve seconds after completing a drilling job.

(3) When a thick drill bit is used

Your arm is subjected to larger reaction force when a

thicker drill bit is used. Be careful not to be moved by

the reaction force. For this, establish a foothold, hold

the unit tightly with both hands perpendicularly 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.

CAUTION

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
