Drive belt
Chain sawmill with electric motor
(FIG. 54)
The drive belt becomes worn as the sawmill is used.
The belt should be replaced after 200 hours of
operation to avoid a belt failure during operations. If
the drive slips or the belt needs to be adjusted
frequently, this is a sign that the belt needs to be
replaced. Replace the belt as follows:
1. Disconnect the connector from the distribution
box.
2. Disconnect the belt guard (A).
3. Completely remove the belt adjuster (B).
4. Disconnect the electric motor by loosening the
screws.
5. Carefully lift up the motor and replace the belt.
6. Ensure that the belt is correctly positioned in the
tracks (C) on both pulleys.
7. Screw the motor into position and tension the belt
with the tension screw (B). Check the belt tension
with your thumb (D) and install the belt guard (A).
