2.11 Emissions
The noise level (emission) of the drilling-milling machine is below 78 dB(A). If the drilling-mil-
ling machine is installed in an area where various machines are in operation, the acoustic
influence (emission) on the user of the drilling-milling machine may exceed 85 dB(A) at the
workplace.
We recommended the use of soundproofing ear protection. Remember that the duration of the
noise pollution, the type and characteristics of the working area and operation of other machi-
nes influence the noise level at the workplace.

Machine parts falling off forklift trucks or other transport vehicles could cause very
serious or even fatal injuries. Follow the instructions and information on the transport
case:
• centres of gravity
• suspension points
• weights
• means of transport to be used
• prescribed shipping position
WARNING!
Use of unstable lifting equipment and load suspension devices that break under load can
cause very serious injuries or even death.
Check that the lifting and load suspension gear has sufficient load capacity and that it is
in perfect condition.
Observe the rules for preventing accidents.
Hold the loads properly.
Never walk under suspended loads!
3.3 Storage
ATTENTION!
Improper storage may cause important parts to be damaged or destroyed.
Store packed or unpacked parts only under the intended environmental conditions.
“Environmental conditions“ on page 14
Consult the company if the drilling-milling machine or
accessories have to be stored for a period of more than three months or under different environ-
mental conditions than those given here.

Page 16
3.4 Installation and assembly
3.4.1 Requirements of the installation site
The working area for operation, maintenance and repair work must not be hindered.
The mains plug of the drilling-milling machine must be freely accessible.
3.4.2 Load suspension point
WARNING!
Danger of crushing and overturning. Proceed with extreme caution when lifting, installing and
assembling the machine.
Secure the load suspension device around the drill-mill head. Use a lifting sling for this pur-
pose.
Clamp all the clamping levers at the drilling-milling machine before lifting the drilling-milling
machine.
Make sure that no add-on pieces or varnished parts are damaged due to the load suspen-
sion.
3.4.3 Installation
Check the horizontal orientation of the base of the drilling-milling machine with a spirit level.
Check that the foundation has sufficient floor-load capacity and rigidity. The total weight
amounts from 103 to 115 kg.
ATTENTION!
Insufficient rigidity of the foundation leads to the superposition of vibrations between the
drilling-milling machine and the foundation (natural frequency of components). Insuf-
ficient rigidity of the entire milling machine assembly also rapidly causes the machine to
reach critical speeds, with unpleasant vibrations, leading to bad milling results.
Position the drilling-milling machine on the intended foundation.
Attach the drilling-milling machine using the provided recesses in the machine base.
WARNING!
The quality of the substructure and the kind of fixture of the machine stand to the sub-
structure has to assimilate the loads of the drilling-milling machine. The substructure
needs to be even. Please check the horizontal alignment of the substructure of the dril-
ling-milling machine.
Fix the drilling-milling machine to the substructure at the provided recesses at the stand. When
using an optionally available machine substructure, it also needs to be anchored safely and
firmly. We recommend the use of shear connector cartridges or heavy-duty bolts.
