4.16 Engine/Motor Drive Belt Adjustment

1. On sawmills equipped with an electric motor, the drive belt is adjusted by adjusting the tensioner

screw nuts (see the figure below).

See Figure 4-16.

2. To adjust the drive belt on sawmills with a gas engine, increase or reduce the steel cable connecting

the tensioner handle with the belt tensioner. If necessary, adjust also the length of the throttle cable

connecting the tensioner with the engine throttle. The drive belt is tensioned properly if the drive

pulley is fully engaged when the tensioner handle is in the down position. The throttle cable is

adjusted properly if the engine runs at full rotational speed when the tensioner handle is pushed

down. When the tensioner handle is released, the engine should return to idle and the drive pulley

should stop spinning.
