SECTION 4 SAWMILL OPERATION
4.1
Hydraulic Control Operation
AC sawmill:
The hydraulic controls are operational when the key switch is on except
when the saw carriage is moving forward.
DC & 550-600V AC sawmill:
The hydraulic control levers become operational when the
contacts at the bottom of the carriage touch the power strip on the frame tube. The
hydraulic control levers will only work when the cutting head is close enough to the front
end of the mill to touch the power strip. On remote mills after Rev. A5.00, a second power
strip is located at the rear of sawmill frame to allow operation of the hydraulic clamp, side
supports and toe boards with the cutting head at the rear of the mill. Avoid high-current
operations such as loading or turning logs unless the saw head is in contact with the front
power strip.
See Figure 4-1.
Hydraulic units have seven control levers to load, clamp, turn and level
logs.
Use the hydraulic control levers to get the mill ready to load a log.
DANGER!
Keep all persons out of the path of moving
equipment and logs when operating sawmill or loading and
turning logs. Failure to do so will result in serious injury.
CAUTION!
Always make sure the engine is running before
operating the hydraulic controls. Operating the controls
without the engine running will result in power drainage
from the battery. Holding the hydraulic switches halfway up
or down also will cause excessive drainage from the bat-
tery.
