Product Specific Safety Precautions

1.Fire Hazard! Do not fill gas tank when the engine is running. Do not operate if gasoline has been spilled. Clean spilled gasoline before starting the engine. Do not operate near a pilot light or open flame.

2.Operate the engine in well ventilated areas only. Carbon Monoxide is produced during operation and is deadly in a closed environment. Early signs of Carbon Monoxide poisoning resemble the flu, with headaches, dizziness, or nausea. If you have these signs, the engine may not be working properly, or is being used indoors. Get fresh air immediately.

3.Avoid burns from the engine. Certain parts of the engine become very hot during use. Do not touch the engine until it cools down after use.

4.Install this product on a proper surface. Locate on a flat, level, and solid surface that is capable of supporting the weight of the Log Splitter and the log being split.

5.Do not operate the engine with safety guards removed. While the engine is running, do not attempt to reach around the safety guards for maintenance or any other reason.

6.If the engine is installed indoors, exhaust fumes must be piped out of the building using leak-free, heat-resistant piping. Pipes and silencer should not use any flammable materials, nor should they be installed near the same. Engine exhaust fumes should be within legal limits.

7.Engine fuel and fumes are flammable, and potentially explosive. Use proper fuel storage and handling procedures. Always have multiple ABC class fire extinguishers nearby.

8.Never store fuel or other flammable materials near the engine.

9.Do not smoke, or allow sparks, flames or other sources of ignition around the engine, fuel tanks, or batteries. Fuel vapors are explosive.

10.Keep hands, arms, long hair, loose clothing, and jewelry away from pulleys, belts, and other moving parts. Be aware that when engine parts are moving fast they cannot be seen clearly.

11.The engine can product high noise levels. Prolonged exposure to noise levels above

85 dBA is hazardous to hearing. Always wear ear protection when operating or working around the Gas Engine when it is running.

12.Before use, always place wheel blocks to keep the Log Splitter from moving.

13.Rope off a wide area around the Log Splitter to keep spectators safely away from log splitting operation.

14.Always wear leather gloves when handling split logs to avoid cuts.

Warning:The warnings, cautions, and instructions discussed in this instruction manual cannot cover all possible conditions and situations that may occur. It must be under- stood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator.

Unpacking

When unpacking, check to make sure that all the parts are included. Refer to the Assembly Drawing and Parts List at the end of this manual. If any parts are missing or broken, please call Harbor Freight Tools at the number on the cover of this manual as soon as possible.

Operation

Pre-Operation Procedures

Caution: Failure to add oil to the Engine before use will damage the Engine and void the factory warranty. Engine oil is the key factor in engine performance. Do not use Engine oil with additives. Do not use two-stroke gasoline-oil. Using these will shorten Engine life. See Specifications on page 2 for recommended oil type. Also, add 1.5 gallons of quality hydraulic fluid to the reservoir tank before use.

1.Check that all engine and hydraulic mounting nuts and bolts, and hoses are tight.

2.Check engine oil level (See illustration below, left.) If needed, add oil as listed in

Specifications, Engine, on page 2.

Unscrew the oil Dip Stick and wipe clean. Insert the Dip Stick back into the hole and screw it in. Remove it again and check the oil level. Full is indicated by oil on the Upper Level mark. Use a siphon to avoid spilling the oil. Carefully screw the plastic

Dip Stick back into the metal Engine crankcase to avoid stripping the plastic threads on the Dip Stick.

3.Check Air Filter. Unscrew Air Filter Housing Nut and remove the Air Filter Housing and

Filter Elements. If dirty or dusty, clean. (refer to the Maintenance Section, page 8).

Caution: Never run the Engine without the Air Filter assembly. Damage will occur to Engine.

4.Check and add hydraulic fluid to the Hydraulic Fluid Tank as needed (up to 1.5 gallons). You can use 10 W AW or Dextron lll automatic transmission fluid. You need to change the fluid every 100 hours of usage. See photo at the top of page 6.

5.To add hydraulic fluid, pull off the Hydraulic Fluid Fill Tube Cap. Check the level by reading the attached dip stick. See the photo at the top of page 6.

6.Fill the Gas Tank (outdoors) up to 1-1/2??? from the Tank opening lip with unleaded gasoline containing at least 85 octane. Do not top-off tank. Replace Gas Cap.

Fire Hazard! Do not fill Gas Tank when the Engine is running, or near a pilot light or open flame, or when the engine is still hot. Do not smoke when refueling. Do not operate Engine if gasoline has been spilled. Allow any spilled gas to evaporate before starting Engine.

7.Inflate tires to 60 PSI.

8.Remove Wheel Bearing Dust Proof Caps (15) and verify Bearings (19) are completely packed with bearing grease.

If they are not greased, remove Bearings and completely pack with bearing grease.

Replace Bearings and Wheel Bearing Covers. If you are not familiar with this procedure, have a qualified mechanic do it.

Engine Controls

Starting the Engine

During this procedure, refer to the photos of the Engine Controls on page 6.

1.Push the Throttle Lever to the fast (left) position, then slightly to the right.

2.Close the Choke by pulling it to the left.

Note: If the Engine is already hot, it is not necessary to close the Choke.

3.Push the red Prime Button three times to inject gas into the carburetor.

Wait two seconds between each prime. If this is the first time starting the new Engine, prime five times. Excessive priming will flood the Engine and it will not start.

4.Gently pull the starter Rope Handle until it engages. Then pull it hard and all the way out. Slowly guide the Rope Handle back into the starter housing.

The Engine should start. Try again if it does not start. Refer to the Troubleshooting section if problems persist. Let the engine run for five minutes to warm up.

5.Push in the Choke Lever to the right to close.

6.Push the Throttle Lever (all the way) to the fast position (left).

Stopping the Engine

1.Push the Throttle Lever all the way to the Off (right) position.

Engine should shut down. When Engine is cool, remove Spark Plug cable to avoid restarting accidently.

2.Push the Ram Control forward and backward until all pressure is used up.

Splitting Logs

1.Place wheel chocks (not supplied) on each side of the wheels to keep the Log Splitter from moving. See photo below.

2.Allow the engine to run for a few minutes to build up pressure in the hydraulic system.

3.Pull back on Ram Control to retract the Ram, then move to neutral (center) position.

4.Center a log on the Main Body (23), no more than 20??? long and 14??? in diameter.

6.Stand to one side of the Engine, then push the Ram Control forward until the log is split.

7.When the log is split, pull back on the Ram Control to retract the Ram.

Prepare the next log to be split. The Log Splitter hydraulic system can split up to four logs per minute.

Basic Troubleshooting

Maintenance

Before performing maintenance procedures, it may be helpful to locate the items to be serviced in the photos on page 6, or the Assembly Drawing and Parts List at the end of this manual. Some Engine maintenance, adjustments, and repairs must be completed by a qualified, small engine mechanic. Refer to the Briggs and Stratton Service Manual (sup- plied).

Scheduled Maintenance

Cleaning Air Filter

Using compressed air, blow the dust from both elements and the Filter Base on the Engine. If the Filter Elements cannot be cleaned, wash the foam element with mild soap and water, and dry. Purchase a new paper Filter Element if necessary. Reinstall Filter Elements, Air

Filter Housing, and Nut. See photo below, left.

Cleaning and Replacing Spark Plug

1.Pull off the Spark Plug Cable.

2.Using a socket wrench (not supplied), carefully unscrew the Spark Plug. Wait for the Engine to cool to avoid burning hands.

3.Clean Spark Plug with a steel brush. If the insulator is damaged, replace Spark Plug.

Caution: Using other than the recommended Spark Plug replacement type can damage the Engine (see Specifications on page 2).

4.Measure the Spark Plug electrode gap with a feeler gauge (not supplied). See illustration above, left.

It should be set to 0.030??? (0.76 mm). If adjustment is necessary, bend the side electrode carefully, then re-measure. If Spark Plug Gasket is damaged, replace it.

5.Replace Spark Plug by hand for the first few turns, then tighten with the socket wrench completely. Securely tighten. A Spark Plug with a new Gasket requires 1/2 more turns to tighten than the used Gasket which requires 1/8 to 1/4 turns to tighten.

Changing Oil

1.Run the Engine for five minutes to warm up the oil, then shut off the Engine.

2.Place a drain pan under the Drain Plug. (Drain plug screw is located under the Engine.)

3.Remove the Dip Stick and unscrew the Drain Plug.

4.Allow all the oil to drain out into the pan. Pour the used oil into a container with a lid. Deliver used oil to a recycling center. Do not dump oil into the earth or storm drain.

5.Replace Drain Plug and securely tighten.

6.Add 1/2 quart of 10W 30 motor oil through a siphon into the Dip Stick fill hole. Fill until the oil reaches the Upper Level line of the fill hole.

7.Replace the Dip Stick, being careful not to strip its plastic threads.
