EQUIPMENT AND ACCESSORIES

Due to safety reasons always use additional handle when operating the demolition hammer. Additional handle can be xed at any point on the hammer casing circumference and features stepped adjustment of its position.

• Loosen the locking knob for additional handle (7).

• Rotate the additional handle (6) on the hammer casing circumference to the most comfortable position considering the work at hand.

• Pull the additional handle away from the hammer casing and set up in appropriate position (g. A).

• Tighten the locking knob for additional handle (7) to x it securely.

INSTALLATION AND REPLACEMENT OF WORKING TOOLS

The demolition hammer is designed to operate with working tools with SDS Max shanks. Clean the hammer chuck and working tool before installation. Apply thin layer of grease onto shank of the working tool. Disconnect the power tool from power supply.

• Hold the xing sleeve (2) of the SDS Max chuck (1) and overcome the spring resistance to pull it to the back.

• Insert working tool shank into the chuck and slide it to mechanical stop (it may be necessary to turn the working tool so it can reach appropriate position) (g. B).

• Release the xing sleeve (2), it will nally lock the working tool.

• If the xing sleeve does not return to its default position, remove the working tool and repeat the whole operation. Working tool is properly seated if it cannot be removed without pulling o the xing sleeve. High eciency of the demolition hammer operation can be achieved by using sharp and undamaged working tools.

DEINSTALLATION OF WORKING TOOL

Just after the operation is nished, the working tool may be hot. Avoid direct contact and use appropriate protective gloves. Clean the working tool after removal.

• Pull the xing sleeve (2) to the back and hold.13

• Remove the working tool with your second hand by pulling it to the front (g. B). OPERATION / SETTINGS

SWITCHING ON / SWITCHING OFF

The mains voltage must match the voltage on the rating plate of the demolition hammer. Switching on – press the switch button (4) and hold in this position. Switching o – release pressure on the switch (4). Do not use the demolition hammer when the switch is faulty.

HAMMER OPERATION, DEMOLITION

Hold the hammer rmly with both hands and switch it on. To achieve the best eciency possible during operation, apply stable and moderate (not excessive) pressure on the demolition hammer (excessive pressure would lead to eciency loss). The hammer is factory lubricated and is ready for operation. Demolition hammer lled with solid grease requires some time to heat up, depending on the surrounding temperature. New demolition hammer requires some time to work before it achieves full working eciency. If the demolition hammer is not used for a long time, or operates in low temperature, allow the hammer to work with no load for 3-5 minutes. Sharp working tools improve work eciency. Ventilation holes with no dirt reduce risk of motor overheating. During operation small quantities of grease may come up from between the working tool and tool holder. This is normal.

OPERATION AND MAINTENANCE

Disconnect the tool from power supply before starting any regulation, maintenance or repair.

• Soft brush or compressed air are best for cleaning the demolition hammer.

• Do not clean the hammer with water or chemical cleaning agents.

• Store the hammer in dry place, beyond reach of children.

• Keep ventilation holes of the motor unobstructed.

• In case of excessive commutator sparking have the technical condition of carbon brushes of the motor checked by a qualied person.

• Entrust replacement of power cord and other repairs only to authorized service workshop. GEAR GREASING It is recommended to check grease in the gear every 40 hours of the demolition hammer operation and lling up or changing grease according to needs.

• Unscrew the xing screws and remove the cover (3).

• Use special key to unscrew lubrication inlet plug (8) (g. C).

• Rell or replace used grease, use a cloth to remove it.

• Fill the gear with new grease (approximately 30 g).

• Install lubrication inlet plug (8) and the cover (3). When changing grease do not use more grease than approx. 30 g. Otherwise the demolition hammer will not work properly. After the supplied grease ends, use another available grease that is resistant to high temperature.

REPLACEMENT OF CARBON BRUSHES

Replace immediately worn out (shorter than 5 mm), burnt or cracked motor carbon brushes. Always replace both carbon brushes at a time.

• Unscrew xing screws (9) and remove the motor cover (5) (g. D).

• Unscrew the carbon brush covers (10) and remove worn out carbon brushes (g. E).

• Remove any carbon dust with compressed air.

• Insert new carbon brushes (carbon brushes should easily move into brush holders) (g. F).

• Install carbon brush covers (10) and the motor cover (5). After the carbon brushes are replaced, start the hammer with no load and wait until the carbon brushes t to the motor commutator. Entrust replacement of carbon brushes only to a qualied person. Only original parts should be used.14 All faults should be repaired by service workshop authorized by the manufacturer.

nformation regarding noise and vibration The following levels of emitted noise, such as emitted acoustic pressure LpA and acoustic power level LwA and measurement uncertainty K have been given in the instruction manual as dened in the EN 60745 standard. The following vibration value (acceleration value) ah and measurement uncertainty K have been determined as dened in the EN 60745 -2-6 standard. The vibration level provided in this instruction manual have been determined according to the measurement procedure as dened in the EN 60745 standard and can be used for comparison of power tools. This can be used for preliminary assessment of exposure to vibrations. The provided vibration level is representative for main applications of the power tool. If the power tool is used for other applications or with other working tools, and if it is not suciently maintained, the vibration level may vary. The aforementioned reasons may increase the exposure to vibrations during the entire operating period. In order to precisely estimate the exposure to vibrations, periods should be accounted for, in which the power tool is switched o, or when it is switched on, but not operated. Thus, the total exposure to vibration may prove considerably lower. Additional safety measures should be taken to protect the user against eects of vibrations, such as: maintenance of the power tool and its working tools, ensuring proper temperature of the hands and proper organisation of work.
