planned maintenance


Good and high-quality maintenance is required to ensure the safety and productivity of your forklifts at all times. Technical training, the right tools, shop handbooks, and model-related software should be provided to operators or service technicians performing maintenance work.



Before each shift, a technician or the driver of the industrial truck must perform a technical inspection. You as the operator must ensure that the safety of the driver, other persons or the industrial truck is not adversely affected at any time. If major defects are identified during the inspection, such defects must be reported immediately and the industrial truck must be put “out of operation” and, if necessary, repaired before the next use. You can find the exact procedure for daily inspections of your industrial truck in the operator’s manual. Since the daily inspections are required by the legislator in terms of product safety, we recommend that you document the inspections. Your CLARK partner will gladly help you perform and document the inspections.



The manufacturer provides a regular maintenance schedule; such maintenance is more extensive than the daily inspection. This does not only include lubrication and oil changes, but also a full-scale inspection of the entire forklift. All industrial trucks in your fleet should have a regular maintenance plan that should be specific for each model. The operator’s manual of each forklift describes scheduled maintenance or service intervals.

Examples of regular servicing are:
  • Regular maintenance as per manufacturer’s instructions to maintain the manufacturer’s warranty
  • Annual leak test of the LPG system
  • Annual safety inspection as per FEM 4.004
  • Annual exhaust fume test for diesel forklifts in accordance with TRGS 554



A forklift is not like a passenger vehicle or commercial truck. The options for its use are diverse and thus many components and maintenance requirements differ. In order to be able to work with a forklift, safety requirements have to be implemented and met prior and during the work. CLARK recommends deploying only those workers trained by CLARK Europe and skilled technicians when performing servicing activities or repairs of CLARK machines. Never let your drivers repair forklifts themselves.

Only use your CLARK partner’s technicians for maintenance and repairs of your forklift. Your CLARK dealer has the special tools needed, fully equipped customer service vehicles and the know-how required to maintain an industrial truck. Regular attendance in the technical trainings of CLARK Europe GmbH is mandatory for every CLARK partner (see certificate of attendance). Thus, you can rest assured that skilled CLARK service technicians can be trusted. In addition, the CLARK dealers have support staff and can get technical support directly from CLARK Europe. All CLARK service technicians have the repair manuals and software versions necessary to perform quick and quality repairs.

Service technicians must also be trained in safety measures such as the correct jacking and securing of machines, the use of the correct tools and wearing protective clothes.

If your employees wish to maintain batteries, make sure that they wear appropriate gear and are trained appropriately. Electric devices are subject to special maintenance requirements that must be satisfied at all events. If you have questions or concerns, your CLARK dealer can send a battery specialist to assist you.

The safe and smooth operation of the industrial truck can be affected by the quality of your regular servicing activities. Therefore, only use skilled CLARK technicians and spare parts approved by CLARK. Original CLARK spare parts ensure proper fitting, durability and safe operation of your industrial truck. Parts not approved by CLARK may not work properly and might result in early wear or accidents.
