2. Description

2.1 Use of the product as directed

The DCH 230 is an electrically‐powered diamond cutter and the DCH 180‑SL is an electrically‐powered diamond slitting tool, both designed for professional use in the construction industry. The DCH 230 is designed for cutting mineral materials using diamond cutting discs without water and can also be used for cutting metals when fitted with a synthetic resin‐bonded fiber‐reinforced cutting disc. The DCH 180‑SL is designed for slitting mineral materials using diamond cutting discs without water. A vacuum cleaner with the appropriate filter, e.g. Hilti VCD 50 vacuum cleaner, must be used when cutting mineral materials. In order to avoid electrostatic effects, a vacuum cleaner equipped with an antistatic hose should be used. Use only diamond cutting discs with a maximum permissible peripheral speed of at least 80 m/sec (16000 ft/min) or synthetic resin‐bonded fiber‐reinforced cutting discs with a maximum permissible peripheral speed of at least 80 m/sec (16000 ft/min). 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. 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. The machine may be used only in a dry environment. 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. 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 / service indicator”) Theft protection system indicator (optional) (see section “Operation / TPS theft protection system (optional)”)

2.7 Guard (hood) with guide wheels

Cutting and slitting work on mineral materials may be carried out only when the power tool is equipped with a dust removal hood with guide wheels.

2.8 Electronic overload protection

The electronic overload protection system monitors current input and thus protects the power tool from overload. If the motor is overloaded through application of excessive working pressure, the power tool’s performance drops noticeably or it may come to a complete standstill. A standstill should be avoided. Permissible overload cannot be given as a specific value as it depends on the temperature of the motor. If the power tool has been overloaded, release the pressure applied and then allow it to run under no load for approx. 30 seconds.

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 14 AWG 12 AWG

Mains voltage 110‐120 V

Do not use extension cords with 16 AWG conductor cross section.

125 ft

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 provide a power output in watts of at least twice the value printed on the type 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 (option for the DCH 230)

The DCH 230 can also be fitted with an optional depth gauge. This improves dust removal performance for cutting mineral materials. The desired maximum cutting depth can be set with the aid of the cutting depth scale on the hood extension. The depth gauge is standard equipment with the DCH 180‑SL.
