Frequently Asked Questions - CHE 5-40 SDS-max Flex

What type of tool is the Flex CHE 5-40 SDS-max?

It is a professional rotary hammer and chipping hammer intended for drilling masonry and concrete, as well as for light chipping work.

How to change the working mode?

Turn the working mode selector (reference 3) to the desired position: rotary hammer, chipping hammer, or chisel position adjustment. Perform this adjustment only when the tool is at a standstill.

How to adjust the chisel position?

Place the selector on the chisel adjustment position (corresponding symbol). Turn the chisel to the desired angle (12 positions, every 30°). Then return the selector to chipping mode.

How to change the tool (drill bit or chisel)?

Pull the locking sleeve backward, remove the used tool. To insert a new tool, clean and lightly grease the shank, insert it while turning until it locks. Check by pulling on it.

What protective equipment to wear during use?

Always wear safety glasses, ear protection, and light respiratory protection. Use protective gloves to handle hot tools.

What to do if the safety clutch activates?

Immediately turn off the tool. The clutch activates in case of overload (torque limit exceeded). After cooling, you can resume working by reducing pressure.

How to maintain the tool?

Regularly clean the device and the ventilation slots with dry compressed air. The carbon brushes are self-cutting: when the tool stops, have them replaced by an authorized service center. Do not unscrew the gear housing during the warranty period.

When to replace the carbon brushes?

The tool stops automatically when the brushes are worn. Replace them only with original parts from the manufacturer via an authorized service center. Watch for excessive sparks on the commutator.

What is the maximum drilling diameter in concrete?

The maximum drilling diameter in concrete is 40 mm. For masonry (hard metal core bit), it can reach 90 mm.

What is the power of this tool?

The rated power input is 1150 W. The maximum impact energy is 10 J according to EPTA procedure 05/2009.

Protection class II (completely insulated)

Important safety information

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.

Before using the power tool, please read and follow:

– these operating instructions,
- the "General Power Tools Safety Rules" in the enclosed booklet (leafletno.: 315.915),
– the currently valid site rules and the regulations for the prevention of accidents.

This power tool is state of the art and has been constructed in accordance with the acknowledged safety regulations.

Nevertheless, when in use, the power tool may be a danger to life and limb of the user or a third party, or the power tool or other property may be damaged. The power tool may be operated only if it is

• as intended,
  – in perfect working order.

Faults which impair safety must be repaired immediately.

Intended use

The hammer drill and chisel hammer CHE 5-40 SDS-max is designed

– for commercial use in industry and trade,
– for hammer drilling in masonry and concrete for compound/injection anchor attachment and through-holes,

– for simple trimming work to remove plaster, masonry and light concrete,

– to be used with suitable tools recommended by the manufacturer for this power tool.

Safety instructions for hammers

■ 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 power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. 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 instructions

■ Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to explosion. Penetrating a water line causes property damage or may cause an electric shock.

■ When working with the machine, always hold it firmly with both hands and provide for a secure stance. The power tool is guided more secure with both hands.

- Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.

■ Do not use the power tool if it has a damaged power cord. Do not touch the damaged power cord and pull out the mains plug if the power cord is damaged during work. Damaged power cords increase the risk of an electric shock.

■ Only use tools with SDS-max tool holder. Pull on the tool to check that it is locked properly.
■ Have a damaged dust cap replaced immediately. The dust cap prevents the ingress of dust into the tool holder.
■ 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).
■ Identify the power tool with stickers only. Do not drill any holes into the housing.
■ The mains voltage and the voltage specifications on the rating plate must correspond.

Noise and vibration

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

The A evaluated noise level of the power tool is typically:

– Sound pressure level L _pA : 96 dB(A);

– Sound power level L _WA : 107 dB(A);

– Uncertainty K: 3 dB.

Total vibration value:

• when hammer drilling:
  – Emission value a_h : 8.9 m/s 2
  – Uncertainty K: 1.5 m/s ^2

- when chiselling:

• Emission value a_h : 14.2 m/s
  – Uncertainty K: 1.5 m/s ^2

ATTENTION!

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

NOTE!

The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 62841 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.

The declared vibration emission level represents the main applications of the tool. However if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period.

For a precise estimation of the vibration load the times should also be considered during which the power tool is switched off or even 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 accessories, keep the hands warm, organisation of work patterns.

CAUTION!

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