IMPORTANT INFORMATION FOR LOG SPLITTER USERS

ALWAYS:

Use clean fluid and check fluid level regularly Use Dexron II Automatic Transmission Fluid oi

10W non-foaming hydraulic fluid. Use a filter (clean or replace regularly) Use a breather cap on fluid reservoir Keep end of reservoir return tube below fluid k vel Make certain pump is mounted and aligned prdperly Use a flexible “spider” type coupling between (jngine

and pump driveshafts Keep hoses clear and unblocked Bleed air out of hoses before operating Flush and clean hydraulic system before startup after

any malfunction or servicing Use “pipe dope” on all hydraulic fittings Allow time for warmup before splitting wood Prime the pump before initial startup by turninc over

the engine with spark plug disconnected Split wood with the grain (lengthwise) only

NEVER:

Use fluid below 0° F., or above 150° F. Use a solid engine/pump coupling Force pump when mounting

Operate through relief valve for more than several

seconds

Attempt to adjust unloading or relief valve settings

without pressure gauges Operate with air in hydraulic system Use Teflon tape on hydraulic fittings Warm up engine apart from pump in cold weather Attempt to cut wood across the grain

CONDITIONS WHICH WILL VOID YOUR WARRANTY

1. Failure to maintain proper fluid level in reservoir will void your warranty, causing permanent damage to pump by allowing air to be drawn into pump. Flu d will become foamy. Refer to “Initial Preparation” in the Operation section of this manual.

2. Changing the relief valve setting or pressure adjustment of control valve without proper knowledge and instruction from the factory will void your warranty. A very minor adjustment could destroy the structural and safety limits for which the unit was designed. The system will produce more power than the structure will with stand. Higher pressure could cause the hoses to burst, cylinder to rupture and intense fluid releases, which could result in serious personal injury. Disassembling the pump will void your waranty. If replacement is necessary, merely disconnect and replace.

3. Do not attempt to adjust pump settings, as they are adjusted by the manufacturer at the factory. Use of incorrect hydraulic fluid will void yo jr warranty. Use only Dexron II automatic transmission fluid or 10W

4. non-foaming hydraulic fluid.

5. The flexible pump coupler must be inspected regularly. Allowing the coupler to deteriorate will void your war ranty. Deterioration of spider insert and jrolonged use after deterioration will destroy pump bearings and engine bearings, along with total destructi<»n of coupler hubs.

6. Improper beam lubrication will cause premature wear and looseness. Lubricate the beam regularly. Lack of lubrication will void your warranty.

7. Improper adjustment of splitting wedge v^ill void your warranty. Become familiar with the proper tolerance required for adjustment of the splitting wee ge as instructed in the Adjustment section of this manual. a. If wedge is too loose, cylinder beam and wedge wear will result. Allowing the wedge to loosen and be

used under operating stress will cause damage which will not be covered under warranty.

b. If wedge is too tight, severe beam dam age will result which will not be covered under warranty.

8. Warranty card must be mailed or delivered directly to factory. Proper information must be completed and mailed as per instructions. No warranty reiiords on file may result in delay.

9. Do not overheat the hydraulic system. Excessive heat will destroy the hydraulic system with hardened Orings and excessive friction.

10. Do not attempt to start in temperatures under 20° F. without pre-heating fluid in reservoir. Excessively cold fluid cannot circulate and draw into pump. Warranty will be void.

11. Repair any leaks in hydraulic system immediately. Unattended leaks will cause air to enter system and/or decrease fluid level in reservoir, causing damage to the hydraulic system which will not be covered by war ranty.

RULES FOR SAFE OPERATION

THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH, IF NOT FOLLOWED, COULD ENDANGER THE PERSON AL SAFETY AND/OR PROPERTY OF YOURSELF AND OTHERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL BEFORE ATTEMPTING TO OPERATE YOUR LOG SPLITTER. FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY RESULT IN PERSON AL INJURY. WHEN YOU SEE THIS SYMBOL— ^ HEED ITS WARNING.

^ 3.

Your log splitter was built to be operated according to the 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

1. Before operating this splitter, read and understand this manual completely. 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.

2. 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 equip

ment, not a toy. Therefore, exercise 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 con trol until the helper is clear of the area. More accidents occur when more than one person operates the log splitter than at

any other time.

No one should operate this unit while intoxicated or while tak

ing 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.

PREPARATION

1. 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.

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

3. Always wear safety shoes. A dropped log can seriously injure

your foot.

4. Always wear safety glasses or goggles while operating your

splitter. A piece of splitting log could fly off and hit your eyes.

5. If you wear gloves, be sure they are tight fitting without loose

cuffs or draw strings.

6. Use your log splitter in daylight, or under good artificial light.

7. Never operate your splitter on slippery, wet, muddy or icy sur

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

DANGER

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

9. Never attempt to move the log splitter over hilly or uneven ter rain without a tow vehicle or adequate help.

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

11. 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.

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

OPERATION

1. Stand behind the reservoir tank when operating. See illustra tions.

2. Know how to stop the unit and disengage the cont 'ols.

3. Never place hands or feet between log and splitting wedge or between 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.

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

5. Do not step over your log splitter when the engire is running. You may trip or accidentally activate the splitting wedge if you step over. If you need to get to the other side, wall; around.

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

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

8. Only use your hand to operate the splitting wed je or control lever. Never use your foot or a rope or any ott er extension device. This could result in your inability to stop your splitter quickly enough to avoid injury.

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

10. Never attempt to split woods across the grain. Sime types of wood may burst or fly out of your splitter and resi ilt in injury to you or a bystander.

11. For logs that are not cut square, the longest port on of the log should be rotated down and the most squan^ end placed against the splitting wedge.

12. Keep your work area clean. Immediately remove split wood around your splitter so that you do not stumble aver it. Clean chips and dirt off end plate (wood platform) aftr r each log is split, or whenever necessary to maintain flat cot tact between wood and end plate (platform).

13. Never move the log splitter while the engine is rur ning.

14. Never leave your log splitter unattended with thn engine run ning. Shut off the engine if you are leaving your splitter, even for a short period of time. Someone could accide itally activate the splitting wedge and be injured.

15. Do not run engine in an enclosed area. Exhaust jases contain carbon monoxide. This odorless gas can be Jeadly when inhaled.

16. Be careful not to touch the muffler after the enc ine has been running. It will be HOT!

17. If the equipment should start to vibrate abnormally, stop the engine and check immediately for the cause. Vibration is gen erally a warning of trouble.

18. When cleaning, repairing or inspecting, make certain all mov ing parts have stopped. Disconnect the spark plug wire and keep the wire away from the plug to prevent ac( idental start ing.

3. Replace all damaged or worn parts such as hydraulic hoses and fittings immediately with manufacturer approved replace ment parts.

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

5. 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.

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

7. Do not service or repair your log splitter without disconnecting the spark plug wire and moving it away from the spark plug.

8. 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.

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

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

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

12. 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 look ing for discoloration.

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

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

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

16. Completely drain fuel tank prior to storage. This guards against accumulation of fuel fumes which could result in a fire hazard.

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

CUSTOMER RESPONSIBILITIES

1. Do not operate your splitter in poor mechanica, condition or when in need of repair.

2. Periodically check that all nuts, bolts, screws, hosje clamps and hydraulic fittings are tight to be sure equipm ;nt is in safe working condition. Where appropriate, check all pfety guards and shields to be sure they are in the proper p psition. Never operate your splitter with safety guards, shields lor other pro tective features removed. These safety devices i are for your protection.
