1. Move the saw head so the blade is positioned directly above one of the bed rails. Measure from the
bottom edge on a down-set tooth of the blade to the top of the bed rail.
2. Loosen the scale bracket mounting bolts and nuts, adjust the scale position until the scale indicator
reads the distance measured in the previous step. Retighten the bracket mounting bolts and nuts.
Example: if the measurement from a down-set tooth of the blade to the top of the bed rail was 14 3/4"
(375 mm), make sure the indicator reads 14 3/4" (375 mm) on the scale.
3.17 Engine/Motor Drive Belt Adjustment
1. On LX50 sawmills equipped with the electric motor, the drive belt is adjusted by adjusting the
tensioner screw nuts (see the figure below).
See Figure 3-17.
2. To adjust the drive belt on sawmills with the 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 (3600 r.p.m.) 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.
