Hydraulic ram
moves forward and
backward slowly, or
does not move in
either direction.
1. Hydraulic fluid tank empty or low.
2. Air in hydraulic system.
3. Hydraulic control lever at fault.
4. Hydraulic control valve at fault.
5. Damaged hydraulic ram piston seals.
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).
Hydraulic ram
moves forward
slowly or stalls, but
retracts correctly.
1. Log exceeds splitter capacity.
2. Splitting wedge dull; log unsuitable for
splitting.
3. Hydraulic control lever at fault.
4. Hydraulic fluid too low or contaminated.
5. Hydraulic control valve at fault.
6. Damaged hydraulic ram piston seals.
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).
Hydraulic ram
retracts slowly or
not at all, but moves
forward correctly.
1. Hydraulic control lever at fault.
2. Hydraulic control valve at fault.
3. Damaged hydraulic ram piston seals.
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).
Splitter will not split
wood or splits it too
slowly.
1. Log improperly positioned on bed.
2. Splitting wood against grain.
3. Air in hydraulic system.
4. Splitting wedge dull.
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).
Hydraulic fluid
leaking from
hydraulic cylinder
or other points on
machine.
1. Air bleed screw opened too much.
2. Air in hydraulic system.
3. Oil plug not fully tightened.
4. Hydraulic control valve pressure release
hex bolt not fully tightened.
5. Hydraulic control valve seals worn/
damaged.
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).
Hydraulic fluid
burnt or has tan
discoloration.
1. Hydraulic fluid old or contaminated with
water.
1. Change hydraulic fluid (
Page 22).
