Noise/Vibration Information; Technical Data - Proxxon BFW 40/E Manual

Translation of the Original Operating
Instructions BFW 40/E
Dear Customer,
With the BFW 40/E you have purchased a machine
which is ideal for milling and drilling metal, plastic and
wood. This machine is equipped with:
- a high-quality, quiet running permanent magnet DC
motor with a high tractive force throughout the entire
speed range;
- high-performance voltage supply unit with low voltage
safety feature;
- stepless speed control for optimal adaptation of speed
to different materials and tools;
- continuous spindle for true-running precision
with / " external thread for mounting collet chucks

or drill chuck;
- Ø 43 mm spindle neck for mounting in drilling or milling
stands according to European standards;
- 6 steel collet chucks from 2.35 to 6 mm for optimal
true-running.
WARNING!
Read all safety warnings and instructions. Fail-
ure to follow all safety warnings and instructions
listed below may result in electric shock, fire and/or seri-
ous injury.
KEEP ALL SAFETY WARNINGS AND INSTRUCTIONS
FOR THE FUTURE !

Noise/vibration information

The information on vibration and noise emission has
been determined in compliance with the prescribed stan-
dardised and normative measuring methods and can be
used to compare electrical devices and tools with each
other.
These values also allow a preliminary evaluation of the
loads caused by vibration and noise emissions.
Warning!
Depending on the operating conditions while operating
the device, the actually occurring emissions could differ
from the values specified above!
Please bear in mind that the vibration and noise emis-
sion can deviate from the values given in these instruc-
tions, depending on the conditions of use of the tool.
Poorly maintained tools, inappropriate working methods,
different work pieces, too high a feed or unsuitable work
pieces or materials or unsuitable bits and cutters (here:
saw blade) can significantly increase the vibration load
and noise emission across the entire work period.
To more accurately estimate the actual vibration and
noise load, also take the times into consideration where
the device is switched off, or is running but is not actu-
ally in use. This can clearly reduce the vibration and
noise load across the entire work period.
Warning:
• Ensure regular and proper maintenance of your tool
• Stop operation of the tool immediately if excessive vi-
bration occurs!
• Unsuitable bits and cutters can cause excessive vibra-
tion and noises. Only use suitable bits and cutters!
• Take breaks if necessary when working with the de-
vice!
