Frequently Asked Questions - TE 70 ATC HILTI

How do I change the drill bit on the Hilti TE 70 ATC?

To change the bit, first ensure the tool is unplugged. Pull back the chuck sleeve (SDS Max) and insert the bit, then release the sleeve to lock it in place.

What does ATC stand for and how does it work?

ATC stands for Active Torque Control. It automatically shuts off the motor if the bit binds, preventing injury and tool damage.

Can the TE 70 ATC be used for chiseling?

Yes, it has a chiseling mode. Use the mode selector to switch to chiseling. For chisel positioning, rotate the selector to the positioning setting.

What is the maximum drilling diameter in concrete?

The TE 70 ATC can drill up to 40 mm in concrete using a carbide bit.

How do I maintain the tool?

Regularly clean the air vents and the chuck. Replace carbon brushes when worn. Have the tool inspected by a Hilti service center annually.

What type of chuck does the TE 70 ATC use?

It uses an SDS Max chuck, which is standard for heavy-duty rotary hammers.

Is the depth gauge adjustable?

Yes, the depth gauge can be adjusted without tools. Loosen the side handle, set the desired depth, and tighten.

What should I do if the ATC activates frequently?

Frequent activation may indicate a dull bit or excessive pressure. Use a sharp bit and let the tool do the work. If persistent, check for damage.

Can I use the TE 70 ATC with a dust extraction system?

Yes, it is compatible with Hilti dust extraction systems. Attach the adapter to the rear of the tool.

Where can I find replacement parts?

Replacement parts are available through Hilti service centers and authorized dealers. Use only genuine Hilti parts.

2 Description

2.1 Use of the product as directed

The power tool is an electrically-powered rotary hammer (TE 70-D/AVR) or combihammer with pneumatic hammering mechanism. The ATC (Active Torque Control) function incorporated in the TE 70-ATC/AVR and TE 80-ATC/AVR provides greater operating comfort while drilling

The power tool is designed for drilling in concrete, masonry, metal and wood and can also be used for chiseling (not the TE 70-D/AVR).

The power tool may be used to work only on non-flammable materials.

Under certain conditions, the power tool is suitable for use for mixing (see "Tools, accessories" and "Operation").

Working on materials hazardous to the health (e.g. asbestos) is not permissible.

Nationally applicable industrial safety regulations must be observed.

The power tool is designed for professional use and may be operated, serviced and maintained only by trained, authorized personnel. This personnel must be informed of any special hazards that may be encountered. The power tool and its ancillary equipment may present hazards when used incorrectly by untrained personnel or when used not as directed.

The working environment may be as follows: construction site, workshop, renovation, conversion or new construction. The power tool may be used only in a dry environment.

Do not use the power tool where there is a risk of fire or explosion.

The power tool may be operated only when connected to a power supply providing a voltage and frequency in compliance with the information given on its type identification plate.

Modification of the power tool or tampering with its parts is not permissible.

To avoid the risk of injury, use only genuine Hilti accessories and insert tools.

Observe the information printed in the operating instructions concerning operation, care and maintenance.

3. Plug the supply cord into the power outlet
4. Set the desired drilling power (optional).

NOTE Afterconnecting the supply cor tric supply, the power tool is always set power.

NOTE To set the power tool to reduced power (depends on version), press the reduce-power button. The reduced-power LED lights indicate reduced power. Press the reduced-p button again to switch to full power. The power LED then goes out.

1. Position the power tool and drill bit at the where the hole is to be drilled.
2. Press the control switch slowly (drill at a until the drill bit centers itself in the hole).
3. Press the control switch fully to continue with full power.

NOTE Do not apply excessive pressure. This will not increase the power tool's hammering performance. Lower pressure extends the life of the insert tool.

1. Reduce drilling speed shortly before breaking through in order to avoid spalling.

7.2.2 Active Torque Control (TE 70-ATC/AVR and TE 80-ATC/AVR)

In addition to the mechanical safety slip clutch, the tool is also equipped with the Active Torque Control tem. This system offers additional comfort while drilling as it causes rapid shutdown upon sudden rotation of the power tool about the drill bit axis, e.g. when t drill bit sticks due to hitting a rebar or when the eyes and is tilted unintentionally. When the torque control system has become activated, the power tool can be restarted releasing the control switch and re-engaging it after t motor has stopped rotating (a "click" indicates that t power tool is again ready for operation). Always chow working position in which the electric tool is free to in a counterclockwise direction (as seen by the oper. If this rotation is not possible, the ATC system will unable to react.
