Basic Operations

Locate the splitter as close as possible to the logs you will split. Refer to CIRCUIT REQUIREMENTS, on Page 8 for the maximum length of extension cords.

To split a log:

1. Make sure the bleeder screw is open by first turning it clockwise until it stops and then turning it counterclockwise two full turns.

2. Place the log squarely on the bed as shown in Figure 7. DO NOT try to split a log against the grain by laying it sideways on the bed.

3. With your body and clothing away from log and the hydraulic ram, depress and hold the ON button, then push the control lever down. Keep pressing the ON button while holding the control arm down; the ram will push the log into the splitting head. When the ram stops, immediatley release both the ON but- ton and control arm.

Note: The hydraulic system will be damaged if you try to force the ram forward by holding the controls in the ON position after the ram stops.

4. Clear the pieces of split wood away from the splitter.

Removing a Jammed

Log

If a log does not split and becomes jammed on the splitting wedge, DO NOT try to clear it by hit- ting it from the side or kicking it; this can result in personal injury and damage the splitter.

To safely remove a jammed log:

1. With the ram fully back, set a wooden wedge flat side down on the bed with the narrow end pointing under the log as shown in Figure 8.

Note: A piece of split wood set crossways on the bed may make a good wedge, but it must narrow enough to slide under the end of the jammed log.

2. Start the splitter to push the wedge under the jammed log until the log lifts off the splitting head.

Note: If the first wedge does not free the log, repeat the process using wedges with steeper slopes until the log is free.
