Keep the machine well lubricated. Inject the
lubrication oil ISO VG 32 (summer) or ISO VG

Prior to the next use, after being stored for a
long time, check the machine for free rotation,
then turn on the control switch. If the machine
shaft does not rotate after the motor is running
or the handle is pressed, there may be rust in-
side. Turn off the electric power immediately
to avoid electric damage. In this case, send it
to the service or replace the clamp jaws.
