FILLING THE DIPPER
FILLING THE DIPPER REQUIRES THE COORDINATION OF HOISTING AND CROWDING THE DIPPER
SIMULTANEOUSLY. HOIST THE DIPPER BY PULLING THE REAR DRUM LEVER. AS THE DIPPER STARTS TO
RISE, CONTROL THE CROWD MOVEMENT WITH THE FRONT DRUM LEVER. EASING UP ON THE FRONT DRUM
BRAKE PEDAL WHEN THE REAR DRUM LEVER IS PULLED BACK WILL ALLOW THE DIPPER TO CROWD INTO
THE BANK. WITH THE FRONT DRUM BRAKE APPLIED, THE DIPPER WILL HOIST IN AN ARC THAT WILL
DECREASE THE BITE AS THE DIPPER REACHES THE TOP OF THE BANK. WHEN THE DIPPER IS FILLED, APPLY
BOTH BRAKES AND RELEASE THE REAR DRUM LEVER. RETRACT THE DIPPER BY PULLING BACK ON THE
FRONT DRUM LEVER AND EASING OFF THE FRONT DRUM BRAKE.PEDAL. WHEN THE DIPPER IS CLEAR OF
THE BANK, APPLY THE FRONT DRUM BRAKE PEDAL AND RFLEASE THE FRONT DRUM LEVER.
SWINGING
KEEP BOTH BRAKES APPLIED. PULL CLUTCH LEVER TO SWING TO RIGHT, PUSH TO - SWING TO LEFT. TO
STOP SWING, ENGAGE LEVER IN OPPOSITE SWING POSITION. SWING THE SHOVEL TOWARD THE DUMPING
POINT. (RETRACTING DIPPER AND SWINGING MAY BE ACCOMPLISHED SIMULTANEOUSLY) .
