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.
Status Meaning
The service indicator lights red. • End of service interval – servicing is due. After
the LED lights for the first time, the diamond
cutter can continue to be used for several hours
(running time) before the automatic cut-out is
activated.
• Return the product to Hilti Service for servicing
in good time in order to ensure that it is always
ready for use.
The service indicator blinks red. • The product is defective. Have the product
repaired by Hilti Service.
3.9 Depth gauge
The depth gauge is not one of the items supplied with the DCH 300 diamond cutter, but it is available
as a retrofit (accessory).
The desired maximum cutting depth can be set with the aid of the cutting depth scale on the depth gauge.
The depth gauge also improves dust removal performance.
