Setup & Operation
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. Fail-
ure to do so will result in serious injury.
CAUTION!
Always make sure the engine is running before oper-
ating 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 battery.
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 bed level.
2.
Raise the log loader lever to extend the legs of the log loader out as far as they will go.
3.
The chain securing the log loading arm to the log turner arm will be tight. Raise the log turner lever
to raise the turner arm until there is slack in the chain.
4.
Unchain the loading arm from the turner arm.
5.
Lower the turner lever to completely lower the turner arm. 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 dam-
aging the turner and/or falling off the side of the sawmill.
6.
When raising the turner lever, the side supports rise first. After reaching a fully vertical position, the
turner arm will engage and start to rise.
7.
Manually lower the log loader so the legs rest on the ground.
CAUTION!
Be careful when manually lowering the log loader.
Do not drop the loader onto the ground or perform any action
which might break the velocity fuse valves on the loader cylin-
ders. These valves control hydraulic flow and are necessary to
prevent the loading arm from collapsing during use.
8.
Lower the loader lever to lower the loading arm as far as it will go. Logs must be rolled onto the
loading arm one at a time for loading onto the bed of the mill.
9.
The front and rear toe boards should be below bed level. Once a tapered log has been loaded, the
front or rear end of the log may be lifted to parallel the heart of the log to the path of the blade.
