7.1 Setting up
Place of installation The working area around the metal bandsaw should be arranged in accor-
dance with local safety regulations.
In order to achieve good functionality and a long service life for the metal
bandsaw, the place of installation should meet the following criteria.
- The machine may only be installed and operated in dry, ventilated rooms.
- Avoid places near machines that cause chips or dust.
- The place of installation must be vibration-free, i.e. away from presses,
planers, etc..
- The underground must be suitable for sawing work. Pay attention to the
load-bearing capacity and evenness of the ground.
- The underground must be prepared in such a way that the cooling lubri-
cant used cannot penetrate into the ground.
- If necessary, protruding parts, such as stops, handles, etc., must be se-
cured by on-site measures so that persons are not endangered.
- Provide sufficient space for set-up and operating personnel and material
transport.
- Also consider accessibility for adjustment and maintenance work.
- Provide adequate lighting (minimum value: 300 lux)
ATTENTION!
Before setting up the machine, have the load-bearing capa-
city of the underground checked by a specialist. The bottom
or the hall ceiling must support the weight of the machine
plus all additional parts and units, as well as the operator
and materials stored. If necessary, ensure that the ground is
reinforced.
NOTE!
Material damage due to uneven ground!
An uneven surface causes deformations within the work-
shop press. This results in inaccurate machining of the
workpieces.
- Place the metal bandsaw on a flat, vibration-free and even
surface.
