assemble and operate. Keep this manual in asafe place
for future and regular reference and for ordering
replacement parts.
2. Be familiar with all controls and proper operation. Know
how to stop the machine and disengage them quickly.
3. Never allow children under 16 years to operate this
machine. Children,16 years and over, should read and
understand instructions and safety rules in this manual
and should be trained and supervised by aparent.
4. Never allow adults to operate this machine without
proper instruction.
5. Many accidents occur when more than one person
operates the machine. If a helper is assisting in loading
logs, never activate the control until the helper is a
minimum of 10 feet from the machine.
6. Keep bystanders, helpers, pets, and children at least 20
feet from the machine while it is in operation.
7. Never allow anyone to ride on this machine.
8. Never transport cargo on this machine.
9. Hydraulic log splitters develop high fluid pressures during
operation. Fluid escaping through a pin hole opening can
penetrate your skin and cause blood poisoning,
gangrene, or death. Give attention to the following
instructions at all times:
a. Do not check for leaks with your hand.
b. Do not operate machine with frayed, kinked,
cracked, or damaged hoses, fitting, or tubing.
c. Stop the engine and relieve hydraulic system
pressure before changing or adjusting fittings,
hoses, tubing, or other system components.
d. Do not adjust the pressure settings of the pump or
valve.
5. Leaks can be detected by passing cardboard or wood,
while wearing protective gloves and safety glasses, over
the suspected area. Look for discoloration of cardboard
orwood.
6. If injured by escaping fluid, see a doctor immediately.
Serious infection or reaction can develop if proper
medical treatment is not administered immediately.
7. Keep the operator zone and adjacent area clear for safe,
secure footing.
8. If your machine is equipped with an internal combustion
engine and it is intended for use near any unimproved
forest, brush, or grass covered land, the engine exhaust
should be equipped with a spark arrester. Make sure you
comply with applicable local, state, and federal codes.
Take appropriate firefighting equipment with you.

6. Do not change the engine governor settings or
overspeed the engine. The governor controls the
maximum safe operating speed of the engine.
7. When loading a log, always place your hands on the
sides of the log, not on the ends, and never use your foot
to help stabilize a log. Failure to do so, may result in
crushed or amputated fingers, toes, hand, or foot.
8. Use only your hand to operate the controls.
9. Never attempt to split more than one log at a time unless
the ram has fully extended and a second log is needed to
complete the separation of the first log.
10. For logs which are not cut square, the least square end
and the longest portion of the log should be placed
toward the beam and wedge, and the square end placed
toward the end plate.
11. When splitting in the vertical position, stabilize the log
before moving the control. Split as follows:
a. Place log on the end plate and turn until it leans
against the beam and is stable.
b. When splitting extra large or uneven logs, the log
must be stabilized with wooden shims or split
wood between the log and end plate or ground.
12. Always keep fingers away from any cracks that open in
the log while splitting. They can quickly close and pinch
or amputate your fingers.

against the engine before cleaning, or inspecting the
machine.
2. Stop the engine and relieve hydraulic system pressure
before repairing or adjusting fittings, hoses, tubing, or
other system components.
3. To prevent fires, clean debris and chaff from the engine
and muffler areas. If the engine is equipped with a spark
arrester muffler, clean and inspect it regularly according
to manufacturers instructions. Replace if damaged.
4. Periodically check that all nuts and bolts, hose clamps,
and hydraulic fittings are tight to be sure equipment is in
safe working condition.
