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, firmly grasp the ring and turn the

sleeve in the counterclockwise direction.

(4) When the sleeve does not become loose any further,

fix the side handle to retaining ring, hold side handle

firmly, then turn the sleeve to loosen by hand. (Fig. 3)

6. Check the rotational direction (Fig. 4) (DV13VSS,

DV16VSS only)

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

firmly 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

mark).

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

⅜ 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 efficiency,

but may also damage the drill tip.

⅜ 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)

⅜ When the trigger is depressed, the tool rotates. When

the trigger is released, the tool stops.

⅜ 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.

<DV13VSS, DV16VSS only>

⅜ 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

efficiency 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.

CAUTION

In continuous operation, conduct no-load operation

for five 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 efficiency, 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 HITACHI

AUTHORIZED SERVICE CENTER.

5. Replacing supply cord

If the replacement of the supply cord is necessary,

this has to be done by Hitachi Authorized Service

Center in order to avoid a safety hazard.
