DCH 300–X
The product described is an electric cutter designed to be used with diamond cut-off wheels for cutting
mineral materials with or without use of water.
For dry-cutting mineral materials, a dust removal system complete with the appropriate filter must be used.
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 cut-off wheels 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 (cut-off wheel counter-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.
