before changing or adjusting fittings, hoses, tubing, or
other system components.
d. Do not adjust the pressure settings of the pump or
valve.
10. 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 or wood.
11. If injured by escaping fluid, see a doctor immediately. Serious
infection or reaction can develop if proper medical treatment
is not administered immediately.
12. Keep the operator zone and adjacent area clear for safe, secure
footing.
13. If your machine is equipped with an internal combustion

specified in the manual.
7. Logs should be cut with square ends prior to splitting.
8. Use log splitter in daylight or under good artificial light.
SafeHandlingofGasoline
To avoid personal injury or property damage use extreme care in
handling gasoline. Gasoline is extremely flammable and the vapors
are explosive. Serious personal injury can occur when gasoline is
spilled on yourself or your clothes which can ignite. Wash your skin
and change clothes immediately.
a. Use only an approved gasoline container.
b. Extinguish all cigarettes, cigars, pipes, and other sources
of ignition.
c. Never fuel machine indoors.
d. Never remove gas cap or add fuel while the engine is
hot or running.
e. Allow engine to cool at least two minutes before
refueling.
fl Never overfill the fuel tank. Fill tank to no more than 1/2
inch below bottom of filler neck to provide space for
fuel expansion.
g. Replace gasoline cap and tighten securely.
h. If gasoline is spilled, wipe it off the engine and
equipment and move machine to another area. Wait five
(5) minutes before starting the engine.
i. Never store the machine or fuel container inside where
there is an open flame, spark or pilot light as on a water
heater, space heater, furnace, clothes dryer or other gas
appliances.
j. Allow machine to cool at least five (5) minutes before
storing.
1. Before starting this machine, review the "Safety Instructions".
Failure to follow these rules may result in serious injury to the
operator or bystanders.

Always operate this machine with all safety equipment in place
and working. Make sure all controls are properly adjusted for
safe operation.
Operator Zone
a. Horizontal Operating Position: Stand behind the
reservoir tank to operate the control handle and to
stabilize the log as shown in Fig. 1.
b. Vertical Operating Position: Stand in front of the beam
and log as shown in Fig. 1.
Horizontal
Vertical
Figure 1
7. Do not change the engine governor settings or overspeed the
engine. The governor controls the maximum safe operating
speed of the engine.
8. 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.
9. Use only your hand to operate the controls.
10. 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.
11. 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 to
ensure the log remains level and in place on the end plate.

12.
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.
13. Keep your work area clean. Immediately remove split wood
around the machine so you do not stumble over it.
14. Never move this machine while the engine is running.
15. This machine should not be towed on any street, highway or
public road without checking the existing federal, state, or
local vehicle requirements. Any licensing or modifications such
as taillights, etc., needed to comply, is the sole responsibility
of the purchaser. If a "Statement of Origin" is required in your
state, see your local dealer.
16. Do not tow machine over 45 mph.
17. See Transporting the Log Splitter section in this manual for
proper towing instructions once all federal, local, or state
requirements are met.
