Safety instructions

The high frequency spindle is a state of the art product and is safe to operate.

However, the HF spindle may pose a risk in the following cases:

q

If it is installed by untrained personnel.

q

If it is used incorrectly.

q

If it is not used in accordance with its intended use.

The high frequency spindle may only be installed, commissioned, and main-
tained by specialist personnel.

Definition:

Specialist personnel are persons who are familiar with the assem-

bly, installation, commissioning, and operation of the product and have the
relevant qualifications for their area of activity. The operator must closely con-
trol the responsibility, training, and monitoring of these personnel.

DANGER: Due to explosion.

HF spindles are not approved for use in areas at risk of explosion. Use in such
areas may result in explosions.

u

Do not use the HF spindle in potentially explosive atmospheres.

DANGER: Due to flying parts.

The HF spindle operates at high speeds and may therefore be flung away by
these.

u

Operate the HF spindle only if it is installed in the machine or system in a
fixed manner.

Note: Adhere to the limit values.

u

Observe the limit values specified in the technical data.

Note: Take account of the machine.

u

Observe the manual of the machine in which the HF spindle is installed.

u

Observe all safety instructions specified by the machine manufacturer.

u

Ensure that the machine does not cause any hazards (e.g. uncontrolled
movements). Do not install the HF spindle in the machine until this has
been done.

Note. Do not damage the HF spindle.

u

Any damage reduces the accuracy of the HF spindle.

u

Any damage restricts the functionality of the HF spindle.

u

Any damage shortens the service life of the HF spindle.
