General power tool safety warnings entering a power tool will increase the risk of electric shock. d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
This enables better control of the power tool in unexpected situations. f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of these devices can reduce dust-related hazards. g) Use the power tool, accessories and tool bits etc.

Accessories This tool may cause hand-arm vibration syndrome if its use is not adequately managed. Warning: To be accurate, an estimation of exposure level in the actual conditions of use should also take account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle but not actually doing the job. This may significantly reduce the exposure level over the total working period. • • Helping to minimize your vibration exposure risk.
Operating instructions Note: Before using the tool, read the instruction book carefully. INTENDED USE The machine is intended for hammer drilling in concrete, brick and stone. It is also suitable for drilling without impact in wood, metal, ceramic and plastic. A BEFORE PUTTING INTO OPERATION A) CHARGING THE BATTERY PACK The battery pack charger supplied is matched to the Li-Ion battery installed in the machine. Do not use another battery charger.
1 OPERATION INSERTING AND REMOVING DRILL BIT IN SDS Take care that the dust protection cap (2) is not damaged when changing tools. — INSERTING Clean and lightly oil the bit before inserting. Insert the dust-free bit into the bit holder with a twisting motion until it latches. The bit locks itself. Check the locking by pulling on the tool. — REMOVING A Retract back the bit holder locking sleeve (3) and pull out the bit.
A B 4 ON/OFF SWITCH (See Fig. C) 10 Depress the On/Off switch(5) to start and release it to stop your tool. — ON/OFF SWITCH WITH VARIABLE SPEED CONTROL Depress the On/Off switch to start and release it to stop your tool. This tool has a variable speed switch(5) that delivers higher speeds with increased trigger pressure - speed is controlled by varying the pressure applied to the switch. 5 SWITCH LOCK (See Fig. C) C The switch trigger can be locked in the OFF position.
machine is switched off by means of a protective circuit: The inserted tool no longer rotates. For simultaneous drilling and impacting of concrete or masonry, choose the Hammer drilling position. Working hints for your tool For drilling into steel, wood and plastics choose the Rotary drilling position. If your power tool becomes over heated, set the speed to maximum and run no load for 2-3 minutes to cool the motor. SDS-plus tungsten carbide drill bits should always be used for concrete and masonry.
Disposal of an exhausted battery pack prolonged time will reduce the battery pack working time. This can be corrected after several charge and discharge operations by charging & working with your drill. Heavy working conditions such as large screws into hard wood will use up the battery pack energy faster than lighter working conditions. Do not re-charge your battery pack below 0oC and above 30oC as this will affect performance.
