2.1 Use of the product as directed
The DD 120 is an electrically-powered, rig-type diamond core drilling machine for drilling through-holes and blind
holes in (reinforced) mineral materials using diamond core bits and the wet drilling technique (hand-held use is not
permissible).
The machine must be adequately secured to the working surface with an anchor or vacuum base plate before use.
To avoid injury, use only genuine Hilti core bits and DD 120 accessories.
Observe the safety rules and operating instructions for the accessories used.
Observe the information printed in the operating instructions concerning operation, care and maintenance.
Nationally applicable industrial safety regulations must be observed.
The machine, accessories and cutting tools may present hazards when handled incorrectly by untrained personnel or
when used not as directed.
Use of the water collection system in conjunction with a wet-type industrial vacuum cleaner is a mandatory requirement
for working overhead.
An additional means of securing the drill stand must be employed when the machine is secured with the vacuum base
plate (accessory) for horizontal drilling.
Do not strike the base plate with a hammer or other heavy object when making adjustments to it.
Tampering with or modification of the machine, drill stand and accessoriesisnotpermissible.

Do not use extension cords with 1.25 mm² conductors. Use only extension cords equipped with an earth conductor.
2.8 Using a generator or transformer
This machine may be powered by a generator or transformer when the following conditions are fulfilled: The unit must
provideapoweroutputinwattsofatleasttwicethevalueprintedonthetype identification plate on the machine. 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.
NOTE
Switching other machines or appliances on and off can cause undervoltage and/or overvoltage peaks which could
damage the machine. Never operate other machines from the generator/transformer at the same time.

NOTE
The vibration emission level given in this information sheet has been measured in accordance with a standardised test
giveninEN61029andmaybeusedtocompareonetoolwithanother.Itmaybeused for a preliminary assessment
of exposure. The declared vibration emission level represents the main applications of the tool. However if the tool is
used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total working period. An estimation of the level of exposure to
vibration should also take into account the times when the tool is switched off or when it is running but not actually
doing the job. This may significantly reduce the exposure level over the total working period. Identify additional safety
measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep
the hands warm, organisation of work patterns.
