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, fittings, 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.

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

engine and 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. Always operate this machine from the operator zone(s)

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.

SafeHandling ofGasoline

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.

2. Never leave this machine unattended with the engine running.

3. Do not operate machine while under the influence of alcohol,

drugs, or medication.

4. Never allow anyone to operate this machine without proper

instruction.

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 on the control

lever side of the log splitter in front of the wheel 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.
