Possible Solution
1. Fill tank to required level (Page 21).
2. Bleed air out of hydraulic system (Page 4).
3. Replace/repair bent/broken lever.
4. Release pressure in hydraulic control valve
(Page 4); replace hydraulic control valve and flush/
service hydraulic system (Page 22).
5. Replace ram assembly and flush/service hydraulic
system (Page 22).
1. Adhere to maximum log dimensions (Page 5).
2. Sharpen splitting wedge (Page 22); avoid splitting
logs with twisted grain, numerous knots, or high
moisture content.
3. Replace/repair bent/broken lever.
4. Fill tank to required level (Page 21); change
hydraulic fluid (Page 22).
5. Release hydraulic pressure in control valve
(Page 4); replace hydraulic control valve and flush/
service hydraulic system (Page 22).
6. Replace ram assembly and flush/service hydraulic
system (Page 22).
1. Replace/repair bent/broken lever.
2. Release pressure in hydraulic control valve
(Page 4); replace hydraulic control valve and flush/
service hydraulic system (Page 22).
3. Replace ram assembly and flush/service hydraulic
system (Page 22).
1. Position log lengthwise on bed; adhere to maximum
log dimensions (Page 5).
2. Split wood with grain instead of against grain.
3. Bleed air out of hydraulic system (Page 4).
4. Sharpen splitting wedge (Page 22).
1. Fully tighten air bleed screw, then open it two full
turns.
2. Bleed air out of hydraulic system (Page 4).
3. Fully tighten oil plug (Page 21).
4. Fully tighten hydraulic control valve pressure
release hex bolt (Page 4).
5. Replace hydraulic control valve and flush/service
hydraulic system (Page 22).
1. Change hydraulic fluid (Page 22).
