OPERATING INSTRUCTIONS
7.1
General comments
Every person concerned with installation, start-up, operation and maintenance
of the chipper must have read and understood the complete manual, in particu-
lar the section "safety instructions". The user is advised to have this confirmed
by signature of the appropriate personnel.
For the following description it is assumed that the controls have been supplied by
BRUKS-KLÖCKNER GmbH
. If controls have been supplied by the user, they must
be executed in such a way that the functions correspond completely with the func-
tions described in this manual.
7.2
Operation of the machine
When operating with normal loads on an even continuous basis, the chipper will op-
erate automatically without
attendant
.
When operating at maximum capacity with varying infeed material of large dimen-
sions, the infeed should be controlled
by an operator
. The upper feedrolls
will be
lifted up as long as the button "feedrolls up" is depressed. This enables the
operator to make the indeed opening suitable for the required height. When re-
leasing the button the feedrolls will lower again.
Feedrolls can be stopped and reversed to clear any jams or wedged in pieces.
The automatic load control stops the feedrolls upon reaching full load main motor
current. They will start automatically again when the current drops 30% below full
load. (This is adjustable). If the chipper is equipped with a brake (optional), the rotor
run out time is shortened considerably. The rotor brake is activated while depressing
the button rotor brake". The brake applies in intervals to prevent excessive heat build
up in the brake disc. Interlocks must ensure that the brake can only be activated
when the main motor has been switched off.
