3.3 Intended use
DCH 300
The product described is an electric cutter designed to be used with diamond cutting discs for dry-
cutting mineral materials.product.
DCH 300–X
The product described is an electric cutter designed to be used with diamond cutting discs for cutting
mineral materials with or without use of water.
When dry-cutting mineral materials, you must use a dust removal system complete with the appropriate filter
e.g. the Hilti VC 300–17 X universal industrial vacuum cleaner.
Use a vacuum cleaner with anti-static suction hose to avoid electrostatic effects.
Optionally, the product can also be used with synthetic resin-bonded abrasive cutting discs for metal-cutting
without water. Special accessories (80 mm diameter flange assembly, consisting of clamping flange and
reversible flange) are required for this application.
Use the product in push mode only (cutting disc count-rotating).
Operate the product only when it is connected to a power source providing a voltage and frequency in
compliance with the information stated on the type identification plate.
3.4 Possible misuse
Do not use the product in environments where there is a risk of explosion.
Do not use the product for roughing down or grinding.
Do not use the product to work on hazardous or flammable materials (e.g. asbestos, magnesium, wood).
DCH 300
Do not use the product for cutting with water.
3.5 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.
3.6 Restart interlock
The diamond cutter does not restart by itself after an interruption in the electric supply. The on/off switch
must first be released and then pressed again after approx. 1 second.
3.7 Electronic overload protection
The cutter is equipped with an electronic overload protection system that monitors current input.
If the current drawn by the motor is too high, e.g. due to application of excessive pressure by the user, the
electronic overload protection system switches the power tool off.
To switch the power tool on again, release the on/off switch and then press it again.
The user should aim to work continuously with the tool without activation of the automatic cut-out.
The user can prevent activation of this automatic cut-out by reducing the pressure applied to the tool.
3.8 Service indicator
The diamond cutter is equipped with a visual (LED) service indicator.
