Installation and setting up:

Note:

The machine must mot be lifted by the gearbox

(Fig. 1) or

by the cover cap of the motor when transporting. The plastic
caps could break.

The supporting surface must be flat and sufficiently strong to
absorb the vibration generated during work. The machine
must be fastened to the surface using the holes

(Fig. 1)

provided for this purpose. Ensure that the power cable is
outside the danger zone.

Mount the lathe chuck

(Fig. 1) on the main spindle with the

3 screws. Ensure that the chuck seating is free of dust.

Refer to the separately enclosed clamping chuck instructions
for information on using the chuck.

All polished metal parts are supplied with a corrosion protec-
tion coating. This is not intended as a lubricant, but as a pre-
servative only. It must be rinsed off, e.g. with petroleum, befo-
re the machine is used. All guides must be checked and
adjusted if necessary. (See also Chapter „Maintenance”.)

The polished guides and spindles must then be well lubricated
with a suitable machine oil. The chuck guard can then be
mounted.

Note:

Do not oil the any part of the mechanical drive mechanism (belt
pulleys, belts, gearwheels). If there is any excessive noise,
however, it could be advisable to apply a light coat of Molykote
grease to the gearwheels.

Operating:

Attention!

Before turning on the machine, check that the screws of chuck
2 (Fig. 1) are tightened properly, that the chuck key has been
removed, and that support

(Fig. 1) is at a safe distance from

the chuck.

Attention!

Practice without a workpiece clamped in the chuck first. Be sure
to ensure that the turning jaws are tightened securely since they
could be loosened by centrifugal force if there is no resistance.
Practice first by running the machine at low speeds.
Please note that the turning chuck has been oiled slightly and
could throw off oil when run for the first time.

Attention!

Please note that due to the motor design, the motor could
become very hot if allowed to idle for an extended length of
time. Although this does not indicate that the motor is defective,
it is advisable nevertheless to avoid situations of this kind by not
allowing the motor to idle unnecessarily.
