Additional remarks:

Because different materials are used, every plaster or plastic cast has different properties.
While working, try to determine the optimum speed for the respective material.

A lower speed is advantages when cutting through plastic casts. This prevents the plastic from
starting to melt due to friction heat generated during cutting.

Where possible, avoid cutting through plaster casts without wadding when using the HEBU
oscillating cast cutting saw. Injuries can result if the skin has become stuck to the plaster, and
so does not oscillate with the saw blade. Where a plaster cast close to the skin is preferred,
we recommend laying a knitted or felt strip along one side of the arm or leg and drawing a line
precisely above this strip on the surface of the plaster cast using indelible ink. When sawing
open the cast, this line can be used as guiding mark.

When applying a plaster cast following surgery, the position of the operation wound should be
marked on the surface of the plaster cast. This will allow a window to be cut subsequently in
the plaster for removing stitches and observation of the wound.

Cutting a window in the plaster also simplifies the extraction of bone nails and also facilitates
any necessary punctures or incisions.

Metal rails inserted in the plaster cast should not be cut.

While serving, check the retaining screw for a firm fit and if necessary tighten.

Used and blunt saw blades place excessive stress on the motor and should consequently be
continuously checked and exchanged in good time.

To ensure even wear of the saw blade, open the retaining screw and turn the saw blade by
90°.
8 Cleaning and maintenance
Danger of injury through unintentional
activation.
Remove accumulator before cleaning and
maintenance
The following measures should be performed once a week or more often if the saw is used
frequently:
Clean the cooling slots to ensure sufficient ventilation for cooling the motor.
Clean the motor compartment from the outside with a jet of dry compressed air.
Wipe disinfection is suitable for motor housing, accumulator and all accessories, such as saw blades and
an open-end wrench. For this purpose, we recommend products with a pH-value within 9-10, e.g.
MediClean forte from Dr. Weigert.
It is important to ensure that the disinfecting liquid does not enter the interior of the motor.
