IMPORTANT

RULES FOR SAFE OPERATION

THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH, IF NOT FOLLOWED, COULD ENDANGER THE PERSONAL SAFETY AND/OR PROPERTY OF YOURSELF AND OTHERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL BEFORE AT TEMPTING TO OPERATE YOUR LOG SPLIHER. FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY RESULT IN PERSONAL IN

JURY. WHEN YOU SEE THIS SYMBOL-A HEED ITS WARNING.

Your log splitter was built to be operated according to tbe rules for safe operation in this manual. As with any type of power equipment, carelessness or error on the part of the operator can result in serious injury. If you violate any of these rules, you may cause serious injury to yourself or others.

TRAINING

Before operating this splitter, read and understand this manual com pletely. Become familiar with it for your own safety. To fail to do so may cause serious injury. Do not allow anyone to operate your splitter who has not read this manual. Keep this manual in a safe place for future and regular reference and for ordering replacement parts.

Never use your splitter for any other purpose than splitting wood. It is designed for this use and any other use may cause an injury. Your log splitter is a precision piece of power equipment, not a playtoy. Therefore, excercise extreme caution at all times.

Never allow children to operate your log splitter. Do not allow adults to operate it without proper instruction. Only persons well acquainted with these rules of safe operation should be allowed to use your

log splitter.

Only the operator is to be near your log splitter during use. Keep

all others, including pets and children, a minimum of 20 feet away from your work zone. Flying wood can be hazardous. If a helper

is assisting in loading logs, never activate the control until the helper

is clear of the area. More accidents occur when more than one per son operates the log splitter than at any other time.

No one should operate this unit while intoxicated or while taking

medication that impairs the senses or reactions. A clear mind is essential for safety. Never allow a person who is tired or otherwise

not alert to use your splitter.

DANGER

Only operate your splitter on level ground and not on the side of a hill. It could tip, or roiling logs or poor footing could cause an accident. Operating the splitter on level ground also prevents the spillage of gasoline from the fuel tank.

Never attempt to mo\re the log splitter over hilly or uneven terrain without a tow vehicle or adequate help.

Always block the wheels to prevent movement of log splitter while in operation.

Check the fuel before starting the engine. Gasoline is an extremely flammable fuel. Do not fill the gasoline tank indoors, when the engine is running, or while the engine is still hot. Replace gasoline cap securely and wipe off any spilled gasoline before starting the engine as it may cause a fire or explosion.

Both ends of each log must be cut as square as possible to help prevent the log from riding out of the splitter during operation.

OPERATION

• Stand behind the reservoir tank when operating. See illustration.

PREPARATION

Never wear loose clothing or jewelry that can be caught by moving parts of your log splitter and pull you into it. Keep clothing away from all moving parts of your log splitter.

Wear proper head gear to keep hair away from moving parts. Always wear protective hearing devices as needed.

Always wear safety shoes. A dropped log can seriously injure your foot.

Always wear safety glasses or goggles while operating your split ter. A piece of splitting log could fly off and hit your eyes.

If you wear gloves, be sure they are tight fitting without loose cuffs or draw strings.

Use your log splitter in daylight, or under good artificial light. Never operate your splitter on slippery, wet, muddy or icy surfaces.

Safe footing is essential in preventing accidents. Never operate your splitter while attached to a towing vehicle.

• Know how to stop the unit and disengage the controls.

• Never place hands or feet between log and splitting wedge or be tween log and end plate during forward or reverse stroke. To do so may result in crushed or amputated fingers or toes, or worse, you may lose an arm or foot.

• Do not straddle the splitter when using it. A slip in any position could result in a serious injury.

• Do not step over your log splitter when the engine is running. You

may trip or accidentally activate the splitting wedge if you step over. If you need to get to the other side, walk around.

• Never try to split two logs on top of each other. One may fly out and injure you.

• When loading the log splitter, place your hands on the side of the log, not at the ends. Never attempt to load your splitter while the splitting wedge is in motion. You may get caught by the wedge and injured.

• Only use your hand to operate the splitting wedge or control lever.

Never use your foot or a rope or any other extension device. This could result in your ability to stop your splitter quickly enough and cause injury.

• Always keep fingers away from any cracks that open in the log dur ing splitting operation. They can quickly close and pinch or amputate your fingers.

• Never attempt to split woods across the grain. Some types of wood

may burst or fly out of your splitter and result in injury to you or

a bystander.

• For logs that are not cut square, the longest portion of the log should

be rotated down and the most square end placed against the split

ting wedge.

• Keep your work area clean. Immediately remove split wood around your splitter so that you do not stumble over it. Clean chips and

dirt off end plate (wood platform) after each log is split, or whenever necessary to maintain flat contact between wood and end plate (platform).

• Never move the log splitter while the engine is running.

• Never leave your log splitter unattended with the engine running.

Shut off the engine if you are leaving your splitter, even for a short period of time. Someone could accidentally activate the splitting wedge and be injured.

• Do not run engine in an enclosed area. Exhaust gases contain car bon monoxide. This odorless gas can be deadly when inhaled.

• Be careful not to touch the muffler after the engine has been run ning as it is HOT.

• If the equipment should start to vibrate abnormally, stop the engine and check immediately for the cause. Vibration is generally a warn ing of trouble.

• When cleaning, repairing or inspecting, make certain all moving parts

have stopped. Disconnect the spark plug wire and keep the wire away from the plug to prevent accidental starting.

MAINTENANCE

Do not operate your splitter in poor mechanical condition or when in need of repair.

Periodically check that all nuts, bolts, screws, hose clamps and hydraulic fittings are tight to be sure equipment is in safe working

condition. Where appropriate, check all safety guards and shields to be sure they are in the proper position. Never operate your split ter with safety guards, shields or other protective features removed. These safety devices are for your protection.

• Replace all damaged or worn parts such as hydraulic hoses and fit tings immediately with manufacturer approved replacement parts.

• Do not change the engine governor settings or overspeed the engine. This increases the hazard of personal injury. The maximum engine speed is preset by the manufacturer and is within safety limits.

• Do not alter your splitter in any manner such as attaching a rope or extension to the control lever or adding to the width or height of the wedge. Such alterations may cause your splitter to be unsafe.

• Perform all recommended maintenance procedures before you use your splitter.

• Do not service or repair your log splitter without disconnecting the spark plug wire.

• Never store the equipment with gasoline in the tank inside of a building where ignition sources are present, such as hot water and space heaters, clothes dryers and the like. Allow the engine to cool before storing in any enclosure.

• Always store gasoline in an approved, tightly sealed container. Store the container in a cool, dry place. Do not store in a building where ignition sources are present.

• To reduce fire hazard, keep engine free of grass, leaves, wood chips, and excessive grease and oil.

• The hydraulic system of your log splitter requires careful inspec tion, along with the mechanical parts. Be sure to replace frayed, kinked, or otherwise damaged hydraulic components.

• Fluid escaping from a very small hole can be almost invisible. Do not check for leaks with your hand. Escaping fluid under pressure can have sufficient force to penetrate skin, causing serious personal injury. Leaks can be located by passing a piece of cardboard or wood over the suspected leak and looking for discoloration.

• Should it become necessary to loosen or remove any hydraulic fit ting or line, be sure to relieve all pressure by shutting off the engine and moving the control handle back and forth several times.

• Do not remove the cap from the hydraulic tank or reservoir while your log splitter is running. Hot oil under pressure could cause injury.

• The pressure relief valve on your splitter is preset at the factory. Do not adjust the valve. Only a qualified service technician should perform this adjustment.

• Completely drain fuel tank prior to storage. This guards against ac cumulation of fuel fumes which could result in a fire hazard.

• Never store log splitter outside without a waterproof cover. Rain will cause rust on the inside of the cylinder.

TOWING

• This unit should not be towed on any street, highway or public road without checking the existing federal, local or state vehicle re quirements. Any licensing or modifications such as taillights, etc., needed to comply with the existing federal, local or state vehicle requirements is the sole responsibility of the purchaser.

• Before towing, be certain the log splitter is correctly and securely attached to the towing vehicle, and the safety chains are in place. Leave slack in chains for turning allowance.

• Do not allow anyone to sit or ride on your splitter. They can easily fall off and be seriously injured.

NOTE: This unit is equipped with an internal combustion engine and should not be used on or near any unimproved forest-covered, brush-covered or grass-covered land unless the engine’s exhaust system is equipped with a spark arrester meeting applicable local or state laws (if any). If a spark arrester is used, it should be maintained in effective working order by the operator.

In the State of California the above is required by law (Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal lands. A spark arrester for the muffler is available at your Sears Authorized Service Center.
