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 ATTEMPTING TO OPERATE YOUR LOG SPLITTER. FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY. WHEN YOU SEE THIS SYMBOL HEED ITS WARNING.
WARNING:
The Engine Exhaust from this product contains chemicals known to
the State of California to cause cancer, birth defects or other reproductive harm.
DANGER:
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.
Your log splitter was built to be operated according to the rules for safe operation in
1. TRAINING
• Before operating this splitter, read and understand this operator’s 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.
• 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 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 control 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 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.
2. 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 splitter. A piece of splitting log could fly off and hit your eyes.
• Wear leather work 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.
• 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 prevents the spillage of gasoline from the fuel tank.
• Never attempt to move 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.
2
• 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.
3. OPERATION
Vertical Operating Position: Stand in front of the
log splitter.
Horizontal Operating Position: Stand behind the
reservoir tank. See illustrations.
• Know how to stop the unit and disengage the controls.
• 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.
• 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 inability to stop your splitter quickly enough to avoid injury.
• 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.
• 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 splitting 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 carbon monoxide. This odorless gas can be deadly when inhaled.
• Be careful not to touch the muffler after the engine has been running. It will be HOT!
• If the equipment should start to vibrate abnormally, stop the engine and check immediately for the cause. Vibration is generally a warning 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.
4. CUSTOMER RESPONSIBILITIES
• 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 splitter 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 fittings 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
3
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 and moving it away from the spark plug.
• 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 inspection, 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 fitting 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 accumulation 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.
5. TOWING
• This unit should not be towed on any street, highway or public road without checking the existing federal, local or state vehicle requirements. 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.

SECTION 5: 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. Fluid 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 withstand. Higher pressure could cause the hoses to burst, cylinder to rupture and intense fluid releases, which could result in serious personal injury.
3. Disassembling the pump will void your warranty. If replacement is necessary, merely disconnect and replace. Do not attempt to adjust pump settings, as they are adjusted by the manufacturer at the factory.
4. Use of incorrect hydraulic fluid will void your warranty. Use only Dexron III automatic transmission fluid or 10W non-foaming hydraulic fluid.
5. The flexible pump coupler must be inspected regularly. Allowing the coupler to deteriorate will void your warranty. Deterioration of spider insert and prolonged use after deterioration will destroy pump bearings and engine bearings, along with total destruction 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 will void your warranty. Become familiar with the proper tolerance required for adjustment of the splitting wedge as instructed in the Adjustment section of this manual. 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. If wedge is too tight, severe beam damage 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 records on file may result in delay.
9. Do not overheat the hydraulic system. Excessive heat will destroy the hydraulic system with hardened O-rings and excessive friction.
10. Do not attempt to start in temperatures under
o
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 warranty.

Periodically remove and replace the “gibs” (spacers) between the wedge plate and the back plate as follows. See Figure 6.
NOTE: If desired, the gibs may be rotated and/or
turned over for even wear.
1. Remove the center bolt on top of the wedge plate. Slide the gib plate out.
2. Remove and replace the gibs. Reassemble the gib plate, making certain flat washers are in place under the gib plate.
3. Readjust the bolts on the side of the wedge plate as instructed above.
SECTION 12: MAINTENANCE
WARNING: Always stop the engine
and disconnect the spark plug wire before performing any maintenance or repairs.
RESERVOIR FLUID
Check the hydraulic fluid level in the log splitter reservoir tank before each use. Fluid level should be 1-1/2" to 2" from the top of the tank. Change the hydraulic fluid in the reservoir every 100 hours of operation. Disconnect the suction hose from the bottom of the reservoir tank, and drain the fluid into a suitable container. Refill using only Dexron III automatic transmission fluid or 10W non­foaming hydraulic fluid.
NOTE: Drain the fluid and flush the reservoir tank
and hoses with kerosene whenever any repair work is performed on the tank, hydraulic pump or valve. Contaminants in the fluid will damage the hydraulic components. (Should be performed by an authorized service dealer.)
WARNING: Use extreme caution
when working with kerosene, as it is an extremely flammable fluid.
HYDRAULIC FILTER
Change the hydraulic filter every 50 hours of operation. Use only a 10 micron hydraulic filter. Order part number 723-0405.
14
BEAM AND SPLITTING WEDGE
Lubricate both sides of the beam where it contacts the splitting wedge with engine oil before each use to obtain years of service. However, normal wear will occur. The wedge plate on the log splitter is designed so the gibs on the side of the wedge plate can be easily removed and rotated and/or turned over for even wear. Make certain to readjust the adjustment bolts so wedge moves freely, but no excess space exists between the wedge plate and beam.
HOSE CLAMPS
Check the hose clamps on the suction hose (attached to side of the pump) for proper tightness before each use. Check the hose clamps on the return hose at least once a season.
ENGINE
Refer to the separate engine manual for all engine maintenance instructions.
FLEXIBLE PUMP COUPLER
The flexible pump coupler is a nylon ‘‘spider’’ insert, located between the pump and engine shaft. Over a period of time, the coupler will harden and deteriorate. Replacement is needed if you detect vibration or noise coming from the area between the engine and the pump. If the coupler fails completely, you will experience a loss of power.
IMPORTANT: Never hit the engine shaft in any
manner, as a blow will cause permanent damage to the engine. When replacing the flexible pump coupler, proceed as follows. Follow the instructions carefully as the alignment is critical.
1. Disconnect the spark plug wire, and secure it away from the spark plug.
2. Drain gasoline from fuel tank or place a piece of plastic film underneath the gas cap to prevent gasoline from leaking.
3. Using a 1/2 inch socket with an extension, remove the three bolts securing the engine to the engine mounting bracket. The three bolts can be found under the engine mounting bracket.
4. Carefully lift engine off mounting bracket and set aside on a sturdy, level surface.
5. Remove the nylon “spider” insert from the pump coupling half. You may need a pair of needle nose pliers to grasp the insert.
6. Place a new “spider” insert into the pump coupling half.
7. Re-seat the engine making sure to align the pump and engine coupling halves. The pump coupling half can be rotated by hand to aid in alignment. If the two parts are not aligned the unit will not operate properly and damage could occur.
8. Secure engine with three bolts removed in step
3.
9. Reattach spark plug wire to spark plug. Be sure to remove plastic film from under gas cap if necessary.
TIRES
See sidewall of tire for recommended pressure. Maximum tire pressure under any circumstances is 30 p.s.i. Equal tire pressure should be maintained on all tires.
WARNING: Excessive pressure (over
30 p.s.i.) when seating beads may cause tire/rim assembly to burst with force sufficient to cause serious injury.
15
SECTION 13: OFF-SEASON STORAGE
If the log splitter will not be used for a period longer than 30 days, the following steps should be taken to prepare the log splitter for storage.
1. Clean the engine and the entire log splitter thoroughly.
2. Refer to the engine manual for correct engine storage instructions.
3. Wipe unit with an oiled rag to prevent rust, especially wedge and beam.
4. Store unit in a clean, dry area. Do not store next to corrosive materials, such as fertilizer.
NOTE: When storing any type of power equipment
in an unventilated or metal storage shed, care should be taken to rustproof the equipment by coating with a light oil or silicone.
