► Attach the safety chain in such a way
that the machine moves away from
the operator in the event of slipping.
► Lay the safety chain as tightly as
possible around the handle of the
machine.
► Check the secure fitting of the safety
chain and lock before starting work.
► Use the protective equipment

The magnetic clamping force is dependent
on the condition of the substrate. The
clamping force is significantly reduced by
paint, zinc and scale coatings and rust.
The substrate must satisfy the following
conditions in order to achieve sufficient
magnetic clamping force:
■ The substrate must be magnetic.
■ The clamping surface and the magnetic
foot (9) must be clean and grease-free.
■ The clamping surface must be
completely smooth and level.
NOTE
► Clean the substrate and the magnetic
foot (9) of the machine before use.
► Remove any unevenness and loose
rust from the substrate.
► The CS Unitec range of accessories
includes special holding devices.
The best clamping effect is obtained on
low-carbon steel substrate with a thickness
of at least 3/4" (20 mm).

When drilling into low thickness steel, an
additional steel plate (minimum dimensions
4" x 7-7/8" x 3/4" [100 x 200 x 20 mm})
must be placed under the workpiece.
Secure the steel plate to prevent it from
falling.
