during operation.
3. Set log splitter in either the horizontal or vertical position.
NOTICE HORIZONTAL position is used for lighter logs that can easily be loaded onto the beam.
VERTICAL position is used for light logs as well as heavy logs that are difficult to load onto the beam.
Back injury can result from lifting logs onto the log splitter if proper lifting techniques are not used.
4. Load a log onto the beam against the foot plate (MAX LOG LENGTH – 24 in. [61 cm]).
5. Make sure all limbs are clear of crush zones.
6. Push the control valve handle forward (towards the foot plate) to split the log.
7. Push the auto control valve handle backward to return the wedge to its original position.
8. Clear the split wood from the operator zone.
It is normal for the hydraulic fluid to appear foamy/frothy during operation.
If a log gets stuck, embedded or will not split completely, push the control handle in the
reverse direction and allow the log splitter to strip the log from the wedge.
ALWAYS keep hands clear of the log and wedge while it is retracting.
The hydraulic cylinder stroke is designed so the wedge slide stops approximately 1.2 in.(3 cm)
from the foot plate.
