Care of Friction Clutch.

Care should be taken to keep the inside rim of pulley and clutch leather shoes free from oil; if not, the clutch will slip and fail to turn machine over. The clutch and pulleys should be taken off every two weeks and cleaned and oiled; if not, they will become dry on the shaft and cause the mold disk to carry over when the machine stops.

To take off the clutch and pulleys unscrew the nut E (Fig. 13) and loosen screw which holds clutch on the shaft; then clean shaft N (Fig. 11); then put it back and adjust as described in Adjustment of Automatic Stop.

The friction clutch spring S (Fig. 11) is sometimes too weak, and should be strengthened or renewed. To take out this spring, unscrew the cap or end of shaft as shown in Fig. 11.
