2.7 Hydraulic Control Operation
The hydraulic control levers become operational when the main switch located on the starter box is
in the "1" position and the contact at the bottom of the saw head touches the power strip on the
main bed frame tube (a 24V control voltage is delivered). The power strip is located on the left side
of the frame tube.
Power supply must be connected to the electric box located on the hydraulic control box and the
main switch on this electric box must be turned to the "1" position (the white light marked “voltage”
is on).
CAUTION! It is recommended that a 30mA GFI (Ground Fault
Interrupter) be used.
The hydraulic unit turns on automatically after raising or lowering any of the control levers. After
pushing the control lever to the neutral position, the hydraulic unit drive still works for about
5 seconds. It prevents the hydraulic pump motor from frequently starting and overheating.
After taking all of the above steps, if the hydraulic system still does not work properly, check if the
main switch on the electric box (located on the hydraulic box) is in the "1" position (the white light
marked “voltage” is on). Next, make sure that the emergency stop button on the left side of the
control box is not turned on. You can also change the phase sequence by adjusting (with a
screwdriver) the phase inverter located in the socket on the left side of the electric box mounted on
the hydraulic box.
DANGER! Keep all persons out of the path of moving equipment and
logs when operating the sawmill or loading and turning logs. Failure
to do so may result in serious injury.
1. Move the clamp out and down so it will not get in the way of logs being loaded onto the bed.
Lower the clamp in/out lever to move the clamp out toward the loading side of the sawmill.
Lower the clamp up/down lever to lower the clamp below the bed level.
2. Using the log loader lever, completely lower the log loader arms.
3. The chain securing the log loader arm to the turner arm will be tight. Raise the turner arm until
there is slack in the chain.
4. Unchain the loader arm from the turner arm.
5. Lower the turner lever to lower the turner arm below the bed level. Notice that after the turner arm
is all the way down, the side support braces will begin to lower. Release the turner lever after the
turner arm is lowered, but before the side supports begin to lower. This stops the log being loaded
from damaging the turner and/or falling off the side of the sawmill.
6. When raising the turner lever, the side supports rise first.
7. Manually lower the log loader so the legs rest on the ground.
