Bosch Power Tools

Reversing the rotational direction (see figure M)

The rotational direction switch 10 is used to reverse the rota-

tional direction of the machine. However, this is not possible

with the On/Off switch 8 actuated.

Right rotation: Push the rotational direction switch 10

rightward to the stop.

Left rotation: Push the rotational direction switch 10

leftward to the stop.

Set the direction of rotation for hammer drilling, drilling and

chiselling always to right rotation.

Switching On and Off

–To start the machine, press the On/Off switch 8.

–To lock the On/Off switch, keep it pressed and additionally

push the lock-on button 7.

–To switch off the machine, release the On/Off switch 8.

When the On/Off switch 8 is locked, press it first and then

release it.

To save energy, only switch the power tool on when using it.

Setting the Speed/Impact Rate

The speed/impact rate of the switched on power tool can be

variably adjusted, depending on how far the On/Off switch 8

is pressed.

Light pressure on the On/Off switch 8 results in low speed/im-

pact rate. Further pressure on the switch increases the

speed/impact rate.

Preselecting the Speed/Impact Frequency

The required speed can be preselected with the thumbwheel

9 (also while running).

Due to the limitation, the On/Off switch 8 can only be pulled

through to the preset limit.

Gear selection, mechanical (PBH 3000-2 FRE)

Two speed ranges can be preselected with the gear selector

13.

1st gear:

Low speed range; for hammer drilling, chiselling, drilling with

large drilling diameter, screwdriving and thread cutting.

2nd gear:

High speed range; for drilling with small drilling diameter.

– To change gear, push the release button 11 on the mode

selector switch 12 and turn the mode selector switch to

the “drilling” position. Then push the release button 14 on

the gear selector 13 and turn the gear selector to 2nd gear.

Note: The mode selector switch 12 may only be turned when

the machine is switched off. The machine should also be

switched off when turning the gear selector 13.

Hammer drilling and chiselling is possible only in 1st gear. In

these operating modes, the special shape of the gear selector

13 and mode selector switch 12 do not allow switching to

2nd gear.

Before changing the operating mode from drilling to hammer

drilling, Vario-Lock or chiselling, the gear selector

13 must be

set back to 1st gear.

Safety Clutch

 If the tool insert becomes caught or jammed, the drive

to the drill spindle is interrupted. Because of the forces

that occur, always hold the power tool firmly with both

hands and provide for a secure stance.

 If the power tool jams, switch the machine off and loos-

en the tool insert. When switching the machine on with

the drilling tool jammed, high reaction torques can oc-

cur.

Working Advice

Rotation Direction for Chiselling

For chiselling, always set the rotation direction to right rota-

tion. This prevents increased wear of the carbon brushes.

Changing the Chiselling Position (Vario-Lock)

The chisel can be locked in 36 positions. In this manner, the

optimum working position can be set for each application.

– Insert the chisel into the tool holder.

– Turn the mode selector switch 12 to the “Vario-Lock” posi-

tion (see “Setting the operating mode”, page 19).

– Turn the tool holder to the desired chiselling position.

– Turn the mode selector switch 12 to the “chiselling” posi-

tion. The tool holder is now locked.

– For chiselling, set the rotation direction to right rotation.

Inserting Screwdriver Bits (see figure N)

 Apply the power tool to the screw/nut only when it is

switched off. Rotating tool inserts can slip off.

To work with screwdriver bits, a universal bit holder 33 with

SDS-plus shank (accessory) is required.

– Clean the shank end of the adapter shank and apply a light

coat of grease.

– Insert the universal bit holder with a turning motion into

the tool holder until it automatically locks.

PBH 3000-2 FRE
