Safety instructions for cordless rotary hammer

WARNING!

Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference.

■ Wear ear protectors. Exposure to noise can cause hearing loss.
■ Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
- Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.

Safety instructions when using long drill bits with rotary hammers

■ Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
■ Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend, causing breakage or loss of control, resulting in personal injury.

Additional safety rules

• Secure the workpiece. Clamping devices or a vise will hold the workpiece in place better and more safely than holding it by hand.
  ■ Do not drill, fasten or break into existing walls or other blind areas where electrical wiring may exist. If this situation is

unavoidable, disconnect all fuses or circuit breakers feeding this worksite.

■ Position yourself to avoid being caught between the tool or side handle and walls or posts. Should the bit become bound or jammed in the work, the reaction torque of the tool could crush your hand or leg.
■ Use suitable detectors to detect concealed power supply cables or consult your local supply company. Contact with electric cables may result in a fire and/or electric shock. A damaged gas pipe may cause an explosion. Cutting into a water pipe will cause damage to property or may cause an electric shock.
■ When working, hold the power tool firmly with both hands and ensure that you have a secure footing. The power tool is controlled more securely if held with both hands.
■ Only use tools with SDS-plus tool holder. Pull on the tool to check that it is locked properly.
■ Dust released from materials, such as lead paints, some types of wood, minerals and metal, may be hazardous to the operator or people in the vicinity. Inhaling or touching such dust may result in respiratory diseases and/or allergic reactions.

– Ensure the workplace is well-ventilated.
- If possible, use external dust extraction.
- It is recommended to wear a respirator mask belonging to filter class P2.

■ Do not work on materials which release hazardous substances (e.g. asbestos).
■ Use only original batteries with the voltage indicated on the type plate of your power tool. The use of other batteries, e.g. imitations, reconditioned batteries or other makes, increases the risk of injury and damage to property by exploding batteries.
■ Recharge batteries only with chargers recommended by the manufacturer. A charger that is suitable for one type of battery may create a fire hazard when used with another battery.
■ The battery may be damaged by pointed objects such as e.g. nails or screwdrivers or by external application of force. This may give rise to an internal short circuit,

causing the battery to burn, smoke, explode or overheat.

■ Before carrying out any work on the power tool, move the direction preselector switch to the middle position.
■ Operate the direction preselector switch only when the tool is stopped.
■ Identify the power tool with stickers only. Do not drill any holes into the housing.

Noise and vibration

The noise and vibration values have been determined in accordance with EN 62841.

The A-weighted noise level of the power tool is typical:

– Sound pressure level L_pA : 87 dB(A);
- Sound power level L_WA : 95 dB(A);
- Uncertainty: K = 3 dB.

Total vibration value when hammer drilling:

• Emission value a_h : 8.7 m/s
• Uncertainty: K = 1.5 m/s

CAUTION

The indicated measurements refer to new power tools. Daily use causes the noise and vibration values to change.

NOTE

The declared vibration total value(s) and the declared noise emission level given in this information sheet has been measured in accordance with a measurement method standardized in EN 62841 and may be used to compare one tool with another.

It may be used for a preliminary assessment of exposure. The specified vibration emission level represents the main applications of the tool. However, if the tool is used for different applications, with different cutting accessories or poorly maintained, the vibration emission level may differ.

This may significantly increase the exposure level over the total working period.

To make an accurate estimation of the vibration exposure level, it is also necessary to take into account the times when the tool is switched off or running but not actually in use.

This may significantly decrease the exposure level over the total working period.

Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the

cutting accessories, keep the hands warm, organization of work patterns.

WARNING:

• that the vibration and noise emissions during actual use of the power tool can differ from the declared value depending on the ways in which the tool is used especially what kind of workpiece is processes; and
• of the need to identify safety measures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time).

CAUTION!

Wear ear defenders at a sound pressure above 85 dB(A).

i NOTE

It is recommended to use the variable-speed feature for a short time only. Do not continuously operate the tool at different speeds. It may damage the switch.

WARNING

Please start the tool for 2-3 minutes first before use, while the temperature is below zero and there is no impact phenomenon after you turn on the tool.

Hole drilling (see figure P)

When attempting to drill a large diameter hole, it is sometimes best to start with a smaller drill bit then work up to the required size. This prevents overloading the drill. If the drill bit snags, switch off immediately to prevent permanent damage to the drill. Try running the drill in reverse to remove the bit. Keep the drill in line with the hole. Ideally, the drill bit should enter at right angles to the work. If the angle is changed during drilling, this could cause the bit to snap off blocking the hole and perhaps causing injury.

Reduce pressure as the drill is about to break through the item being drilled.

Don't force the tool, let it work at its own pace.

Keep the bit sharp.

Drilling wood (see figure Q)

For maximum performance when drilling larger holes, use auger bits or spade bits for wood drilling.

■ Set the tool to the drill mode.
■ Begin drilling at a very low speed to prevent the bit from slipping off the starting point. Increase the speed as it bites into the wood.
■ When drilling through holes, place a block of wood behind the work piece to prevent ragged or splintered edges on the back of the hole.

Drilling metals

For maximum performance, use HSS drill bits for metal drilling.

■ When drilling metals, use light oil on the drill bit to keep it from overheating. The oil will prolong the life of the bit and increase the drilling efficiency.
■ Set the tool to the drill mode.
■ Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
■ Maintain a speed and a pressure that allow cutting without overheating the bit.

Applying too much pressure will:

• Overheat the tool.
• Wear the bearings.
• Bend or burn bits.

- Produce off-center or irregularly shaped holes.

Drilling masonry (see figure R)

For maximum performance, use high quality carbide-tipped masonry drill bits when drilling holes in brick, tile, concrete etc.

■ Maintain a speed and a pressure that allow cutting without overheating the bit or tool.
Applying too much pressure will:
- Overheat the tool.
- Wear the bearings.
- Bend or burn bits.
– Produce off-center or irregular-shaped holes.
■ Apply light pressure and medium speed for best results in brick. Apply additional pressure for hard materials such as concrete.
- When drilling holes in tile, practice on a scrap piece to determine the best speed and pressure. To prevent the drill bit from skidding/ sliding, first apply two pieces of masking tape to create an "X" shape over the intended drilling spot.
■ Begin drilling at a very low speed to prevent the bit from slipping off the starting point.

Maintenance and care

WARNING

Remove the battery before carrying out any work on the tool.

Cleaning

■ Clean the power tool and grille in front of the vent slots regularly. Frequency of cleaning is dependent on the material and duration of use.
■ Regularly blow out the housing interior and motor with dry compressed air.
