    The hydraulic log splitter is available in the following variants: HS 71 (400V), splitting force 7 t HS 71 (230V), splitting force 6 t The log splitters are equipped with mechanical two-handed controls.
  • Page 4 It is also essential that the carrier (driver) countersign. If the carrier refuses to confirm the transport damages, the best course of action is to refuse receipt as a whole and notify us about it immedia- tely. Without a direct note on the bill of lading, any subsequent claims will not be recognized by the carrier nor the insurer of the transport.

  • Page 8: Safety Instructions

    SAFETY INSTRUCTIONS Servicing, setup, maintenance and cleaning as well as trans- porting the machine may only be performed with the motor turned off and machine parts at a standstill. In order to minimize hazards and avoid damage, it is essential that the instructions regarding operation, assembly, maintenance, repair, malfunctions and similar are complied with.

  • Page 9: Intended Use

    4.1 Intended use The log splitter is designed for operation by 1 person. One machi- ne may never be operated by two or more persons. The „HS 71“ log splitter is intended solely for splitting firewood into smaller pieces in the direction of the grain.

  • Page 10: Operation

    BEDIENUNG 5.1 Mounting guard brackets Before using the log splitter the first time, the guard brackets (1) must be mounted onto the operating arms (see Fig. 1). For transport reasons these are only pre-mounted to the operating arm with one screw (2).

  • Page 11: Checking The Two-Handed Controls

    The control valve is set at the manufacturing plant; further ad- justments may not be attempted. 5.4 Checking the two-handed controls Log splitters are equipped with mechanical two-handed controls. The purpose of this is to ensure that the operator has no way to reach in- to the splitting area when working with the machine (see Fig.4).

  • Page 12: Safety Instructions

    5.6 Remarks concerning safety The log splitter must be set up on a firm and even surface. The work site must be kept free of wood scraps and obstacles (trip- ping hazards). Grit/sand is to be strewn on slippery and slick areas.

  • Page 13: Adjusting The Table

    5.8 Adjusting the table Logs ranging from 550 mm to 1065 mm can be easily split by adjus- ting the splitting table. The table can be adjusted to three heights, wi- thout the need for tools. To adjust the table, unscrew the wing nut (9; Fig.7) on the table mount/column and remove the bolt from the hole.

  • Page 14: Working With The Wood Clamps

    5.9 Working with the wood clamps Wood clamps (12) are attached to the operating arms to hold wood in place during the splitting operation (see Fig. 10). Because of the attached pressure springs (13), the wood clamps can adapt variably to logs of any size (see Fig. 10). The log must be aligned centrally in the wood clamps to ensure opti- mum functionality and proper splitting.

  • Page 15: Transporting The Machine

    TRANSPORTING THE MACHINE On electrically-powered machines, always remove the power plug before changing locations. It is very easy to transport the log splitter. An axle with two wheels is attached at the back. To transport the log splitter, tip it backward slightly until the wheels are touching the ground (see Fig.11).

  • Page 16: Cross Splitter And Splitting Wedge Expander As Accessories

    7. CROSS SPLITTER AND SPLITTING WEDGE EXPANDER AS ACCESSORIES Available as accessories* for our log splitters are a cross splitter and a splitting wedge expander (as additional purchases). The cross splitter splits the firewood into 4 parts in one operation. The splitting wedge expander allows improved and faster splitting of the wood.

  • Page 17: Maintenance And Servicing Work

    MAINTENANCE AND SERVICING WORK Please perform maintenance, servicing and cleaning only after the machine has been turned off (pull plug out of so- cket) and machine parts are at a standstill. 8.1 Regular maintenance tasks The following tasks are to be performed as necessary and/or on a re- gular basis: •...

  • Page 18: Guides In The Splitting Column

    8.3 Guides in the splitting column If squeaking sounds can be heard while running the log splitter, it is necessary to grease the polyamide guides in the splitting column tracks. A standard commercially-available grease can be used for this. The squeaking sounds should cease after doing this. After the polyamide guides have worn out, if the splitting column be- gins showing signs of excessive play to the column tracks, the polya- mide guides must be replaced.

  • Page 19: Decommissioning And Disposal

    9. DECOMMISSIONING AND DISPOSAL When the machine has reached a condition that it cannot be used anymore and must be scrapped, it is necessary to deactivate and dis- mantle it. This means that it must be converted into a state in which it cannot be used anymore for the purpose for which it was constructed.

    11. CIRCUIT DIAGRAM Work on the electrical system of the machine may only be car- ried out by a qualified electrician. For electrically-operated splitter machines use a portable residual cur- rent device (PRCD) if the residual current device (RCD) in the power supply does not have a nominal residual current of a max.

  • Page 22: Overview Of Residual Risk

    12. OVERVIEW OF RESIDUAL RISK 12.1 Prevention of mechanical dangers All dangers stemming from moving parts (splitting wedge) are mi- nimized by the two-handed controls. It is impossible to operate the machine when one operating arm is constantly clamped in the lower position.
