INTRODUCTION
Please read this manual carefully. Following all the instructions provided will ensure that you get excellent results and the best performance from your log splitter.
Our log splitters have been designed and manufactured in compliance with the most recent European safety regulations with particular reference to the EN609 and UNI60204 standards.
The "ZHBZID" control systems have been designed and engineered so that the operator is forced to work in the safety area without any possibility of inserting hands or arms in dangerous areas.
Before transporting, installing or operating the machine, read all parts of this manual, paying particular attention to the specific safety regulations. Operators who are unable to understand any of the languages in which this manual is written are responsible for asking the retailer to provide a manual in their own language.
The operator must also train any other person authorised to use the machine.
Failure to comply in any way with these instructions, improper use of the machine, extraordinary maintenance operations not carried out by skilled, authorised personnel, removal of data plates or markings of any type, removal or tampering with the guards and safety mechanisms of the machine or any other action not expressly authorised that may impair the active and passive safety systems of the machine shall relieve the manufacturer of all and any liability and may result in serious injury and damage.
If the machine is tampered with in any way by unauthorised personnel, the guarantee is automatically null and void. This manual is an integral part of the machine and must accompany it even in the case of transfer of ownership.

2.1 - Size of the logs to be split
Figure 2 on page 2 shows the maximum log sizes that can be split.
The diameter of the log is indicative: a small log can be difficult to split if it has knots or a particularly tough fibre. On the other hand, if the wood has regular fibres it is not difficult to split logs with diameters greater than the maximum shown in Figure 2. It is important not to insist when the log does not split on the first attempt, as the pump may be damaged by the overheating of the oil when the machine is made to work under the maximum stress in the attempt to split excessively hard wood.
2.2 - Recommended oils
We recommend use of the following oils for the hydraulic cylinder:
SHELL TELLUS T22
ARAL VITAM GF22
SP ENERGOL HCP22
MOBIL DTE11 or equivalent
DO NOT USE OTHER GRADE OILS.
Figure 3 on page 2 shows the maximum dimensions of the log splitter.
3 - SAFETY
The information given in this chapter is extremely important for safety purposes. It describes possible hazards tied to use of the machine and instructions for correct use of this to avoid injury or damage.
WARNING: Splitter has been designed and manufactured to split logs of the sizes recommended.
Use of the machine for any other purpose shall be considered improper and the manufacturer shall not be liable for any injuries or damage to be ascribed to improper use of the machine.
The operator must operate the machine drive control with both hands without using other makeshift systems and without tampering with the ZHB control. When the machine is working, persons and animals must be kept at a distance of at least 5 meters from the machine. For the best and safest use, the log splitter must be used on a raised surface of height between 60 and 75 cm.
NEVER ATTEMPT TO TAMPER WITH THE PROTECTIONS OF THE LOG SPLITTER OR TO OPERATE THE MACHINE WITHOUT THESE. FAILURE TO COMPLY WITH THE INSTRUCTIONS GIVEN IN THIS CHAPTER MAY RESULT IN SERIOUS INJURY OR DAMAGE TO PERSONS OR MACHINE.
3.1 - General safety regulations
• The machine must always be used by one operator only.
- Nobody must be allowed to use the log splitter unless they have read the instruction manual and have been instructed in the regulations to follow for correct and safe use.
- The machine must be used by adults only. Use of the log splitter by apprentices of not less than 16 years of age must be supervised by an adult authorised to use the machine.
- Never wear loose, unbuttoned clothing which may become trapped in moving parts.
- Position the machine on a support surface of 60-75 cm height, free from any objects that could prevent complete freedom of movement for the operator while working. The surface must be perfectly levelled to prevent the machine from falling during operation.
- It is prohibited to work with the machine on the ground. This is not only an uncomfortable working position but it can also be dangerous because the operator has to bring his face close to the machine, and thus risks being struck by chips or debris.
- Check that the logs to be split are free from nails or wire, which may fly up or damage the machine. The ends of the logs must be cut square. Branches must be cut off flush with the trunk.
- Never try to split logs larger than those indicated in fig. 2. This could be dangerous and may damage the machine.
- Break wood in the direction of the grain. Do not place wood across the log splitter and leave it in that position for splitting; it may be dangerous and may seriously damage the machine.
- Never attempt to cut two logs at once; one may fly up and hit you.
- If the log moves away from the blade, retract the ram or the blade and turn the log through 90°.
- Do not attempt to load the log in the log splitter while the ram is in motion. You could get trapped and injured.
- Keep your hands well away from any splits and cracks which open in the log; these may close suddenly and crush or amputate your fingers.
- Never force the log splitter for more than 5 seconds keeping the cylinder under pressure in the attempt to split excessively hard wood. After this time interval, the oil under pressure is overheated and the machine could be damaged. It is thus better to stop and rotate the log by 90° to see whether it can be split in a different position. In any case, if you are not able to split the log, this means that its hardness exceeds the capacity of the machine and thus that log should be discarded so as not to damage the log splitter.
- Do not force the blade by pushing the log on the upper part (fig.9), as this can cause the blade to break or damage the body of the machine. Always set the log on the guides.
- Never leave the machine unattended while it is running. If you leave the machine, even for a short time, remove the power supply or any possible cause of accidental start-up.
- The log splitter must never be used by an operator who is under the influence of alcohol, drugs, medicines, or who is tired. A clear mind is essential for safety.
- Never request the assistance of another person to help you remove a jammed log.
- Do not use machines with electric motor if natural gas, petrol fumes or other inflammable vapours are present.
- Check that the electric circuit is adequately protected and that it corresponds with the power, voltage and frequency of the motor; check that there is a ground connection, and a regulation differential switch upstream.
- Use cables with a section of 2.5 mm². Avoid use of free and inadequately insulated connections. Connections must be made with protected material suitable for outdoor use. Do not use extension cables over 10 metres long, as excessively long cables or those with inadequate section can cause voltage drops that prevent motor from developing its full power.
- Never open the pushbutton box on the motor. Should this be necessary, contact a qualified electrician.
- Make sure that the machine and the cable never come in contact with water.
- Treat the power cable with care. Do not attempt to move the machine by pulling the cable. Do not yank the cable to unplug it; keep the cable away from excessive heat, oil and sharp objects.
- Never leave the machine unattended with the power supply "on". Also disconnect the power cable when not in use, when carrying out maintenance work, when changing attachment or moving the machine.
Before operating this machine, it is necessary to fit the wheels on their axle. Insert the wheel (12 in Fig. 4 on page 2) on the axle (11), block it using the elastic washer (13), and cover the hole on the wheel with the respective plastic cap (14) which must be pushed and locked by pressure.
Never use the log splitter if it is not in perfect order or if it needs servicing. Before starting work, check correct functioning of all the safety devices (ZHB, push button).
On the back of the machine, there is a bleed screw that must be loosened by about 3 or 4 turns when the log splitter is being used (Fig. 5, page 2). When the log splitter is to be moved, tighten the screw to prevent oil leakage.
If the fuses blow or the protection valve trips, this means that you are overloading the motor or the electrical installation is not correctly rated. Consult your electrician.
4.1 - Lighting
Lighting must be provided in the entire work area of the log splitter to ensure perfect visibility when operating the machine and during maintenance and adjustments. Even when working outdoors, there must be sufficient light to work safely. Working at times when insufficient light may result in poor visibility of the machine and its components (dawn, dusk, night) is forbidden.
5 - USE
• Position the log splitter on a raised surface of 60-75 cm. - Connect the electric log splitter to the power system. - Never pass the power cable over the log pusher, close to the wedge or anywhere where it may be damaged or severed. - Position the log on the beam as shown in fig. 6, page 3. The supporting guides (fig.1, page 3) help to keep the log at the centre of the wedge. If the log tends to wobble, it must be repositioned turning it so that it remains firmly on the beam. - With your right hand, press thoroughly the button of the electric motor (1), and with your left hand press the control lever (2) all the way down as shown in Fig. 6. The log pusher will go into action and split the log. Warning: if the button is not pressed thoroughly, it could blaze up burning the inside contacts. - If the log does not split immediately, do not force it by maintaining the thrust for more than a few seconds. It is advisable to bring the log pusher back to the resting position and try again by re-positioning the log. It can sometimes be difficult to split small logs if the wood is particularly hard or knotty, while larger logs of wood with regular fibres are very quick and easy to split. If the hardness of the wood exceeds the capacity of the machine, it is better to discard that piece to avoid damage to the machine that may be caused by oil overheating. - Repeat the operation with the pieces obtained so as to split the log into several parts. - On completing the work, pull the plug. Never yank the plug using the cable. Grasp the body of the plug and pull it firmly.
NOTE: During operation, the metal part connected to the motor remains cold or in any case reaches a temperature only slightly higher than the ambient temperature. After several hours of use with particularly difficult wood, the pump may become very hot. This is not a dangerous situation for the machine, which returns to full functioning capacity after being cooled. On the other hand, it is very important not to cause overheating of the oil, and thus the pump, by forcing the machine in an attempt to split logs that exceed the capacity of the machine.
6 - ROUTINE MAINTENANCE
This chapter describes routine maintenance, i.e. operations carried out by the operator, on the log splitter to keep this in perfect working order and therefore reliable for continuous, long-term use. All routine maintenance operations must be carried out with the machine off and in the case of log splitters with electric motor with the power cable disconnected.
Any other maintenance operation not specifically envisaged in this manual must be carried out by authorised personnel only in that hazardous situations may arise for which the operator is not prepared.
In the case in which extraordinary maintenance or part replacement operations are not carried out by authorised personnel, the guarantee shall be immediately null and void and the manufacturer shall be relieved of any responsibility for injury to persons or animals or damage.
6.1 - How to change the hydraulic oil
The spent oil must be replaced with new oil of the type indicated on page 28 every 400 hours of operation. To change the oil, proceed as follows.
- Make sure that the log pusher of the machine is fully retracted.
- Unscrew the cap shown in Fig. 7/A on page 3 and remove it completely.
- Position a container under the log splitter that can hold 4 litres of oil; then tilt the machine to empty the oil (Fig. 7/B).
- Tilt the machine in the other direction (Fig. 7/C) and pour in 2.6 litres of oil of one of the types indicated on page 28.
- Clean the dipstick and insert it to check that the oil level is between the two notches on the stem.
- Clean the cap and washer thoroughly and re-tighten completely but carefully so as not to break the threading of the cap.

WARNING:
NEVER MIX OIL WITH GENERAL WASTE USED OIL MUST BE DISPOSED OF ACCORDING TO CURRENT REGULATIONS IN THE COUNTRY WHERE THE MACHINE IS USED.
6.2 - Refilling the hydraulic oil
Periodically check the oil level, which must be between the two notches on the oil cap dipstick (Fig. 7/A). If the level is low, refill using the recommended types of oil on page 28.
6.3 - Sharpening the wedge
After long periods of operation and when required, sharpen the wedge of the log splitter using a fine-toothed file and taking care to remove any burrs or crushed parts of the metal.
7 - TROUBLESHOOTING
7.1 - How to free a jammed log
- Release both controls: the log pusher will be fully retracted.
- Insert a triangular block of wood under the jammed log and activate the log splitter until the wedge is pushed completely under the piece of wood (fig.8, page 3).
- Repeat the operation with larger pieces of wood until the log is completely free.

WARNING:
• NEVER ASK FOR THE ASSISTANCE OF ANOTHER PERSON WHEN FREEING A JAMMED LOG. - DO NOT TRY TO EXTRACT THE LOG BY HITTING IT WITH A TOOL AND KEEPING THE FOOT BLOCKED, THIS COULD CAUSE THE BREAKAGE OF THE MOTOR BLOCK (FIG. 10 PAGE 3). - ALL THE SAFETY RULES DESCRIBED IN CHAPTER 3 "SAFETY" ON PAGE 29 APPLY WHEN CARRYING OUT THE OPERATIONS DESCRIBED ABOVE.
THE MANUFACTURER SHALL NOT BE HELD RESPONSIBLE IN ANY WAY FOR INJURY TO PERSONS AND ANIMALS OR DAMAGE TO OBJECTS CAUSED BY IMPROPER USE OF THE MACHINE OR FAILURE TO COMPLY WITH THE REGULATIONS DESCRIBED.
