1. Remove the wheel cap and dismantle the wheels.
2. Connect all single parts of the base frame with the machine.
3.  To do so, set up the device horizontally on the floor and place the styro foam padding of the packaging under the riving knife side.
4. Fit the wheels onto the wheel axles of the base frame.

Installing the handle (4)

(enclosed accessories bag a) (fig. 5) Fasten the handle to the U-bar with two cylindrical screws.

Installing the protective guard (L)

1. Fit the protective guard (L) to the trunk guide plate (5) and use the enclosed cylindrical screws and nuts to affix it.
2.  Undo the cylindrical screw with washer that is located on the wheel bracket.
3. Fasten the other end of the strut to the protective guard using the Phillips head screw and nut. (3)
4.  Now guide the open end of the strut (O) between the washer and the wheel bracket, tighten the cylindrical screw (4) again firmly.

Installing the tray table (K + M) (enclosed accessories bag c + d + e)

(fig. 8 + 9 + 10)

1. Attach the tray table (K) to the same side as the protective guard (L). Use two cylindrical screws and spring washers to affix the table to the log splitter. (1) Ensure that the table and the protective guard are level in relation to each other.
2. Undo the screw on the left of the foot.
3. Fasten the other end of the strut to the protective guard using the Phillips head screw and nut, align everything and tighten the screws firmly.
4.  Now guide the open end of the strut (N) between the screw and the foot bracket, tighten the screw slightly.
5. Repeat the process on the other side.
6. Align both tables in relation to each other and use the Phillips head screws and nuts (e) to affix them.

Installing the guard (E – J)

1. Connect the guards (H) and (I) together, use two Phillips head screws, clamping brackets and nuts to affix it.
2. Fasten the guards (H, I, J) to the holes provided for this. These are on the side of the table and the protective guard. Fasten the guard with seven Phillips head screws, clamping brackets and nuts. Fit the protective guard (G) to the control lever protection (11) and use a Phillips head screw and a nut to affix it.
3. Now fasten the guards (E + F) on the top. Fasten them with eight Phillips head screws, clamping brackets and nuts.
4. Fasten the guards (E + F) together using two Phil-lips head screws, clamping brackets and nuts.
   IMPORTANT!
   You must fully assemble the appliance before using it for the first time!

Initial operation

Make sure the machine is completely and expertly assembled. Check before every use:

• the connection cables for any defective spots (cracks, cuts etc.).
• the machine for any possible damage.
•  the firm seat of all bolts.
• the hydraulic system for leakage.
•  the oil level and
• the safety devices

Checking the oil level (Fig. 17)

The hydraulic unit is a closed system with oil tank, oil pump and control valve. Check the oil level regular-ly before every use. Too low an oil level can damage the oil pump. The oil level must be within the middle mark on the dipstick. The machine must stand on level ground. Screw in the oil dipstick fully, to measure the oil level.

Ventilation screw

Before operating your machine, the bleed screw (7) should be loosened by some rotations until air can go in and out of the oil tank smoothly. Failed to loosen the bleed screw will keep the sealed air in hydraulic system being compressed after being decompressed. Such continuous compression/decompression will blow out the seals of the hydraulic system and cause permanent damage to your machine. Before moving your machine, make sure the bleed screw is tightened to avoid oil leaking from this point.

Splitting logs

Only split logs that have been sawn off straight. To do this, proceed as follows:

1. Place the log plain onto the work table (9).
2. Your machine is equipped with Two-hands Control System that requires to be operated by both hands of the user – left hand controls the control lever (12) while right hand controls the push button switch (6).
3. Simultaneously push button switch (6) to start the splitting action.

Releasing one of the control parts leads to the machine stopping immediately. Releasing both control parts causes the pressure plate to retract.
If a piece of log to be split cannot be split within 5 seconds, stop the process immediately. The log is probably too hard for the capacity of your machine. Turn the log 90° and try again. Caution: Continuous operation for more than 5 seconds can pose a risk of overheating. You device may become damaged.

Hoist limiting

It is reasonable to limit the hoist of the pressure plate (10) for short splitting material. Thereto press the control lever (12) and the release button (6) and let the pressure plate (10) move just in front of the splitting material.
Release the release button now and mount the hoist limiting ring (7a) to the housing and tighten it. After-wards you can release the hydraulics lever.
The pressure plate will now be resting in the selected position.

Wrongly placed log (fig. 13)

Always set logs firmly on the log retaining plates and work table. Make sure logs will not twist, rock or slip while being split. Do not force the blade by splitting logs on the upper part. This will break the blade or damage the machine.
Do not attempt to split several pieces of logs at the same time. One of them may fly up and hit you.

Jammed log (fig. 14 + 15)

Do not try to knock the jammed log off. Knocking about will damage the machine or may launch the log and cause accident.

1. Release both controls.
2.  After the log pusher moves back and completely stops at its starting position, insert a wedge wood under the jammed log (see figure 15).
3.  Start the log splitter to push the wedge wood under the jammed one.
4.  Repeat above procedure with sharper slope wedge woods until the log is completely freed.

Electrical connection

The electrical motor installed is connected and ready for operation. The connection complies with the applicable VDE and DIN provisions. The customer‘s mains connection as well as the ex-tension cable used must also comply with these regulations.
Damaged electrical connection cable
The insulation on electrical connection cables is often damaged.
This may have the following causes:

• Passage points, where connection cables are passed through windows or doors.
• Kinks where the connection cable has been improperly fastened or routed.
• Places where the connection cables have been cut due to being driven over.
• Insulation damage due to being ripped out of the wall outlet.
• Cracks due to the insulation ageing.
  Such damaged electrical connection cables must not be used and are life- threatening due to the insulation damage.
  Check the electrical connection cables for damage regularly. Make sure that the connection cable does not hang on the power network during the inspection. Electrical connection cables must comply with the ap-plicable VDE and DIN provisions. Only use connection cables with the marking H05VV-F.
