2 Description

2.1 Use of the product as directed

The DCH 300 is an electrically powered diamond cutter for professional use in the construction industry.

It is designed for cutting mineral materials with diamond discs without use of water.

When cutting mineral materials, a dust removal system equipped with the corresponding filter must be used, e.g. the

Hilti VCU 40, VCU 40‑M or VCD 50 vacuum cleaner.

In order to avoid electrostatic effects, a vacuum cleaner equipped with an antistatic hose should be used.

Use only diamond cutting discs approved for use at a peripheral speed of at least 80 m/sec.

The power tool is to be used exclusively in pushing mode (counter rotation).

The use of liquids, e.g. to cool the disc or suppress dust, is not permissible.

Do not use the power tool for cutting with cutting tools of a type not specified in these operating instructions (e.g.

circular saw blades) or for grinding.

When equipped with synthetic resin-bonded fiber-reinforced abrasive cutting discs, the power tool can also be

used for cutting metals. For this application, use only synthetic resin-bonded fiber-reinforced abrasive cutting discs

approved for use at a peripheral speed of at least 80 m/sec.

The working environment may be as follows: construction site, workshop, renovation, conversion or new construction.

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

Observe the safety rules and operating instructions for the accessories used.

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

The machine 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 machine

and its ancillary equipment may present hazards when used incorrectly by untrained personnel or when used not as

directed.

Themachinemaybeusedonlyinadryenvironment.

Printed: 06.02.2015 | Doc-Nr: PUB / 5127727 / 000 / 01

The machine 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.

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

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

Observe the national health and safety requirements.

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

2.2 Switches

On/off switch with switch-on interlock

2.3 Starting current limitation

The starting current drawn by the power tool is several times higher than its rated current. The electronic starting

current limiter reduces the starting current drawn by the power tool and thus prevents the mains fuse blowing. It also

allows the power tool to start smoothly, without a jolt.

2.4 Restart interlock

The power tool does not restart by itself after an interruption in the electric supply. The switch must first be released

and then pressed again after approx. 1 second.

2.5 TPS theft protection system (optional)

The power tool may be optionally equipped with the TPS theft protection system. If equipped with this feature, the

power tool can be unlocked and made ready for operation only through use of the corresponding TPS key.

2.6 LED indicators

Service indicator LED (see section “Care and maintenance”)

Theft protection system indicator (optional) (see section “Operation”)

2.7 Guard (hood) with guide wheels

Cutting and slitting work on stone may be carried out only when the power tool is equipped with a dust hood with

wheels.

2.8 Electronic overload protection

This power tool is equipped with electronic overload protection.

The electronic overload protection system monitors the current input and thus prevents overloading of the tool during

use.

The power tool switches itself off automatically when excessive pressure is applied resulting in excessively high

electric current input.

After releasing the on / off switch, the power tool can be restarted.

The user can prevent activation of this automatic cut out by reducing the pressure applied to the tool.

The user should aim to work continuously with the tool without activation of the automatic cut-out.

2.9 Using extension cords

Use only extension cords of a type approved for the application and with conductors of adequate gauge. The power

tool may otherwise lose performance and the extension cord may overheat. Check the extension cord for damage at

regular intervals. Replace damaged extension cords.

Recommended minimum conductor gauge (cross section) and max. cable lengths

Conductor cross section 1.5 mm² 2.0 mm² 2.5 mm² 3.5 mm²

Mains voltage 100V -30 m -50 m

Mains voltage 110-120 V --40 m -

Mains voltage 220-240 V 30 m -50 m -

Do not use extension cords with a conductor cross section of less than 1.5 mm².

Printed: 06.02.2015 | Doc-Nr: PUB / 5127727 / 000 / 01

2.10 Using extension cords outdoors

When working outdoors, use only extension cords that are approved and correspondingly marked for this application.

2.11 Using a generator or transformer

This tool may be powered by a generator or transformer when the following conditions are fulfilled: The unit must

provideapoweroutputinwattsofatleasttwicethevalueprintedonthetype identification plate on the power tool.

The operating voltage must remain within +5% and -15% of the rated voltage at all times, frequency must be in the 50

– 60 Hz range and never above 65 Hz, and the unit must be equipped with automatic voltage regulation and starting

boost.

Never operate other power tools or appliances from the generator or transformer at the same time. Where applicable,

use a generator or transformer designed for simultaneous power tool and vacuum cleaner operation. Switching other

power tools or appliances on and off may cause undervoltage and / or overvoltage peaks, resulting in damage to the

power tool.

2.12 Depth gauge (optional)

The power tool can be fitted with an optional depth gauge. This improves dust removal performance for cutting mineral

materials. The maximum cutting depth can be set with the aid of the cutting depth scale on the hood extension.

2.13 The items supplied as standard include:

1 Power tool with DCH‑EX 300 hood

1 Reversible flange 60 mm dia.

1 Clamping flange, 60 mm dia.

1 Clamping nut, M16 x 1.5

1 Clamping nut wrench, 24 mm AF / 10 mm AF

2.14 Cutting disc specifications

Diamond cutting discs in compliance with the requirements of EN 13236 are to be used with the power tool.

Synthetic resin-bonded fiber-reinforced cutting discs in compliance with EN 12413 (straight, not offset, type 41) may

also be used with this power tool for working on metals. In this case, the appropriate DCH 300 ABR disc mount (see

accessories) must be used with the power tool.

The mounting instructions issued by the disc manufacturer must also be observed.

NOTE

The sound pressure and vibration values given in these instructions have been measured in accordance with a

standardized test and may be used to compare one electric tool with another. They may be used for a preliminary

assessment of exposure. The data given represents the main applications of the electric tool. However, if the electric

tool is used for different applications, with different accessories or is poorly maintained, the data may vary. This may

significantly increase exposure over the total working period. An accurate estimation of exposure should also take into

account the times when the tool is switched off, or when it is running but not actually being used for a job. This may

significantly reduce exposure over the total working period. Identify additional safety measures to protect the operator

from the effects of noise and/or vibration, for example: maintaining the tool and the accessories, keeping the hands

warm, organization of work patterns.

Noise information (as perEN 60745‑1):

Typical A-weighted sound power level 117 dB (A)

Typical A-weighted emission sound pressure level 106 dB (A)

Uncertainty for the given sound level 3 dB (A)
