MAINTENANCE

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).

The saw unit’s height adjustment

Maintenance procedures on the components listed below are necessary in order to assure the saw chain’s vertical adjustment.

Runners

The guides that locate the saw saddle should be wiped clean and moistened with oil as required.

Height adjustment screw

The screw must be wiped clean and lubricated if necessary.

Adjusting the saw saddle

The saw saddle’s plastic guides may need to be adjusted after a few hours of use. This is done as follows:

1.Slacken off the three mounting nuts.

2.Screw in the two adjustment screws until there is no play, then tighten the nuts.

3.Check the position of the bar in relation to the log bolsters and adjust if required, see page 20.
