• K uncertainty = 1.5 m/s2

Additional information for electric power tools Warning!
The specified vibration value was established in accordance with a standardized testing method. It may change according to how the electric equipment is used and may exceed the specified value in exceptional circumstances. The specified vibration value can be used to compare the equipment with other electric power tools. The specified vibration value can be used for initial assessment of a harmful effect.
Keep the noise emissions and vibrations to a minimum.

• Only use appliances which are in perfect working order.
• Service and clean the appliance regularly.
• Adapt your working style to suit the appliance.
• Do not overload the appliance.
• Have the appliance serviced whenever necessary.
• Switch the appliance off when it is not in use.

1. Lung damage if no suitable protective dust mask is used.
2. Damage to hearing if no suitable ear protection is used.
3. Health damage caused by hand-arm vibrations if the equipment is used over a prolonged period or is not properly guided and maintained.

Before starting the equipment

Before you connect the equipment to the mains supply make sure that the data on the rating plate are identical to the mains data. Always pull the power plug before making adjustments to the equipment.

Fitting the additional handle (Fig. 2-3/Item 8)
The additional handle (8) enables you to achieve better stability whilst using the hammer drill. Do not use the tool without the additional handle. The additional handle (8) is secured to the hammer drill by a clamp. During the handle clockwise tightens this clamp. Turning it anti-clockwise will release the clamp.

• The supplied additional handle (8) must first be fitted. To do this, the clamp must be opened by turning the handle until it is wide enough for the additional handle to be slid over the chuck (1) and on to the hammer drill.
• After you have positioned the additional handle (8), turn it to the most comfortable working position for you.
• Now turn the handle in the opposite direction again until the additional handle is secure.
• The additional handle (8) is suitable for both lefthanded and right-handed users.

Fitting and adjusting the depth stop (Fig. 4/Item 2)
The depth stop (2) is held in place by the additional handle (8) by clamping. The clamp can be released and tightened by turning the handle.

• Release the clamp and fit the depth stop (2) in the recess provided for it in the additional handle.
• Set the depth stop (2) to the same level as the drill bit.
• Pull the depth stop back by the required drilling depth.
• Turn the handle on the additional handle (8) until it is secure.
• Now drill the hole until the depth stop (2) touches the workpiece

Fitting the drill bit (Fig. 5-6)

• Always pull the power plug before making adjustments to the equipment.
• Release the depth stop (2) as described in 5.2and push it towards the drill handle. This provides free access to the chuck (1).
• Undo the chuck by turning it anti-clockwise with the supplied chuck key (9).
• To ensure that it is perfectly positioned the drill bit or tool should be inserted as far as possible into the chuck. After inserting the drill bit or tool, tighten the chuck (1) by turning the chuck key (9) clockwise until the drill bit or tool is secure. Check that the drill bit is secure in the chuck (1).
• Check at regular intervals that the drill bit or tool is secure (pull the mains plug).

Starting up

Important.
To prevent all danger, the machine must only be held using the two handles (6/8). Otherwise, there may be a risk of suffering an electric shock if you drill into cables.
Switching on and off (Fig. 1)

• To switch on:
• Press the control switch (4).
• To switch off:
• Release the control switch (4).

Hammer stop facility (Fig. 7)
The hammer drill has a hammer stop facility for gentle initial drilling.

• Turn the rotary switch for the hammer stop facility (5) to position (B) to switch off the hammer facility.
• To switch on the hammer facility again the rotary switch for the hammer stop facility (5) must be turned back to position (A).

Rotation stop facility (Fig. 8 / 9)
The rotation function of the hammer drill can be switched off for chiseling jobs.

• To do this, press the button (C) on the rotary switch (3) whilst at the same time turning the rotary switch (3) into position A (see Fig. 8).
• To switch on the rotation facility again, press button (C) on the rotary switch (3) whilst at the same time turning the rotary switch (3) into position B (see Fig. 9).

Important.
Please note that it is not possible to operate the hammer drill with the hammer stop and rotation stop facilities both active at the same time
