• Ensure that people and animals are not around the machine as sharp wood chips my shoot out with great force.
• Always disconnect the plug from the socket before servicing and when not in use and make sure that children cannot start the log splitter.
• Just to be sure, connect the log splitter to a socket via an earth fault breaker.
• Never use the log splitter in the rain or in extreme humidity.
• Never use the machine if the power cable or other parts are damaged. Defective part must be replaced by an expert.
• Keep the working space clean and make sure that the electric motor cooling is not hindered by rubbish covering the cooling flange or the cooling air intake.
• Note! Unscrew the air screw (13) 3–4 revolutions, so that a noticeable air current can be felt during usage. Otherwise the seals in the hydraulic system may be damaged and make the log splitter unfit for use.
• Before use, ensure that the push rod nuts are fastened as the log splitter might be damaged otherwise.

Preparation

1. Place the log splitter on a flat and stable work surface at a practical height.
2. Connect the power cable to a socket, preferably via an earth fault breaker. Remember to place the cable so that it will not damaged when working the log splitter.
3. Unscrew the air screw (13) 3-4 revolutions, so that a noticeable air current can be felt during use.

Working with the log splitter

1. Always place the side with the least amount of knots against the cleaver and always cleave along the grain.
2. Place the log so that it is stable. Use the work bench lateral supports.
3. Start the motor by pressing and then holding down the switch (7).
4. Start the hydraulics: Push the operation lever (11) down (keeping the switch depressed)
5. The pressure plate on the piston rod will now press the piece of wood against the cleaver.
6. Release the operating lever and switch to complete the cleavage (when the log has been split).

Note! The pressure plate automatically stops approx. 12–14 cm from the cleaver.

• Note! If cleaving does not start within 5 seconds in spite of full pressure: release the operating lever and switch and let the pressure plate retract. Then turn the log 90 degrees or turn it around and try again.
• Note! Close the air screw (13) during transport and when storing the machine as oil can seep out. When storing the machine with the air screw open for long periods of time, the oil absorbs moisture from the air which can lead to the hydraulic system rusting inside.
  • Note! Do not cleave using only the upper part of the cleaver as the imbalance might damage the log splitter.

If the log jams

• Stop the cleaving.
• When the pressure plate has returned to its original position: place a wooden wedge under the jammed log.
• Start the log splitter and push the wedge in using the pressure plate.
• If necessary, repeat using a larger wedge.

Maintenance

Changing the hydraulic oil

The hydraulic oil has to be changed at regular intervals (approx. 150 hrs) according to the following:

1. Ensure that the pressure plate is in its original position and disconnect the power cord.
2. Unscrew the oil plug.
3. Lift the pull handle and tip the log splitter over a collecting vessel which holds at least 4 litres and wait until all the oil has run out.
4. Tip the log splitter so that the motor side is up and fill using good quality hydraulic oil (approx. 2.4 litres)
5. Wipe the dipstick and place it in the tank when the log splitter is in a vertical position. Pull it back out and take a reading. The oil level should be between the two markings on the dipstick.
6. Clean the oil plug and screw it back properly so that the oil does not leak out.
7. Check the oil level regularly and when necessary, top it up.

- Ensure that all power cables, plugs and switches are undamaged and in good working order.
- Clean all of the surfaces on the log splitter using a brush and dry cloths.
- Store the machine in a dry, clean and non-corrosive environment out of reach of children. Ensure that the storage temperature does not fall below -25^ C.
- Ensure that all screws and nuts are fastened, especially the drawbar nuts (beside the handle).

Protect the environment

Sort your waste and recycle products instead of throwing them away. All machines, hoses and packing material should be sorted and handled according to local environmental regulations.

Troubleshooting

Problem Possible cause	Suitable measure
The machine failed to cleave the piece of wood.	The log is wrongly placed. Turn around or rotate the log.
	The hardness or diameter of the log is too great.	Try decreasing the diameter or length before cleaving.
	The cleaver is blunt or damaged. Sharpen the cleaver (see Maintenance).
	Oil leakage. Find the leakage and let a qualified technician repair it. Top up the oil.
	Pressure regulator wrongly adjusted. Let a qualified technician with access to testing equipment repair it.
The pressure plate moves abruptly with a jarring sound and strong vibrations.	Oil pressure too low - air in the system.	Check the level and if required top up the oil or repair leakage.
Oil leakage around the piston or other component.	Air pockets in the hydraulic system during operation.	Loosen the bleeding screw 3–4 revolutions before starting operation.
	The air screw has not been tightened before transport.	Tighten the bleeding screw before transport.
	The oil plug is not tightened sufficiently.	Tighten the oil plug.
	The hydraulic valve and/or packing are worn out.	Contact retailer.
