Adjusting Bow Weight
Bowweightis one of the most importantadjustments
of the saw. If the bow weight is not set properly, one
can expect poor performance, crooked cuts, tooth
stripping, stalling, and the blade poppingoff the
blade wheels. The hydraulic feed rate unit will not
compensate for improper bow weight. Bow weight
has been set at the factory and should not need
adjustment. If adjustment is necessary:
1. Disconnect the machine from the power
source.
2. Turn the hydraulic cylinder valve on and place
the the saw arm in horizontal position.
3. Turn feed rate valve on hydraulic cylinder
counter-clockwise until it stops.
