By the way, did you know that we have field repair kits for all our heads?
Our field repair kits are generously equipped spare parts kits with the most essential components for your particular head to minimise standstills.
Our field repair kits differ depending on the head model and equipment, but all contain a cylinder kit encompassing all cylinder functions of your head, all sensors and model-specific spare parts tailored to your particular head and its saw type and control system. In addition to this, they include gasket kits, fasteners and many other parts that you might need.

Your service provider/dealer can help you order a field repair kit so that you always have the most essential components close at hand should the unexpected happen.
You make the claim at the dealership where you bought the head. If you bought it from us, you can make your claim here on the website (Service and support/Claims). If, on the other hand, you bought it from a dealer, you are to contact them instead.
The pressure relief valve/directional valve in the valve assembly for the measuring wheel is most likely broken. See the manual for the item number of the part specific to your head. You can download your manual here on the website if you need to.
Alt. 1: The solenoid is not working.
Alt. 2: The pressure reducing valve needs to be replaced.
Alt. 3: There is an electrical fault, although if the lamp is on, you can rule this out.
The applicable warranty terms and conditions will have been agreed when the head was purchased and can be found in the sales agreement. In order for a warranty to be valid:

  • The head must be operated and maintained in accordance with the manual.
  • The head must be correctly installed in accordance with the installation instructions supplied by Log Max AB.
  • The warranty card must be correctly completed and sent to your dealer, service provider or Log Max AB (depending on who is dealing with your claim) within the time frame stated on the warranty card.

  • We also offer a lifetime hose warranty on heads purchased directly from Log Max AB and used in Sweden and Finland. The hose warranty applies to most hydraulic hoses on the head and means that Log Max AB will supply a new hose free of charge in the event of a failure. The hose warranty is valid for 10,000 operating hours or 5 years. The warranty ceases at whichever of these occurs first and only applies to the first owner of the head.

    PRODUCT INFORMATION AND TECHNICAL SOLUTIONS
    Log Max designs, manufactures and sells harvester heads that can be mounted on any carrier, such as a wheeled or tracked forest machine or an excavator.

    The head is mounted at the far end of the crane, grips the tree, fells it using a hydraulic saw, feeds the tree through the head while delimbing and measuring it, then bucks it into suitable lengths.
    The AFC system is the foundation on which our heads are built, and it enables them to harvest trees with precision and minimal friction.

    The system is patented and involves equipping the head's upper delimbing knife with an analogue sensor to monitor the stem's position in the head. This function enables the stem to be fed through the head more easily.

    You can read more about AFC on the tab titled "A wise choice".
    Four-point measurement is an option on the Log Max 4000, 5000, 6000 and 7000 heads.

    Measurements are made using four points: two opposite each other in the feed rollers, one in the lower delimbing knife, which consists of a sensor, and a baseline in the frame. The sensor's job is to calliper the stem every decimetre and forward the reading to the control system. The control system combines this reading with the values provided by the feed rollers, enabling the system to present extremely good measurement results based on four measurement points.

    We are the only supplier on the market to offer customers four-point diameter measurements. This ensures reliable volume calculations and bucking.
    We are grateful if you send your ideas and opinions regarding our heads and their design to: product@logmax.com.
    Under each head model is a list of all optional equipment suited to that particular head model.

    You can also speak to the sales rep at your nearest dealer for more information.
