PB700 COMBI US - W18XC1052/US - Revised 040113
The PB700 Combi has both a mechanical clutch and electronic overload protection to
protect the motor from overload situations.
If the mechanical clutch operates, the spindle will stop and a rapid clicking sound from the
motor and gearbox will be heard, reduce the feed rate or withdraw the cutter to resume.
If the electronic overload operates, the spindle will stop and will not restart until the motor
has cooled down, in this case the motor should be switched off until the short cooling
period has passed, then the motor can be re-started.
If either of these fail safe features operate whilst drilling, the cause of the overload should
be investigated before carrying on.
MOTOR PROTECTION
OPTIONAL COOLANT SYSTEM
The arbor supplied with PB700 Combi has an internal reservoir for coolant built in.
If additional coolant capacity is required, an external coolant system which feeds through
the arbor is available.
This system must be specified at time of purchase, as the external coolant system can
not be retro fitted to existing machines.
