Service, spare parts and guarantee
Maintenance and repair
The maintenance and repair of modern engines as well as all safety devices require
qualified technical training and a special workshop equipped with special tools and
testing devices.
We therefore recommend that you consult a DOLMAR service centre for all work not
described in this instruction manual.
The DOLMAR service centres have all the necessary equipment and skilled and
experienced personnel, who can work out cost-effective solutions and advise you in
all matters.
Please contact your nearest service centre.
Spare parts
Reliable long-term operation, as well as the safety of your chain saw, depend among
other things on the quality of the spare parts used. Use only original DOLMAR parts.
Only original spare parts and accessories guarantee the highest quality in material,
dimensions, functioning and safety.
Original spare parts and accessories can be obtained from your local dealer. He will
also have the spare part lists to determine the required spare part numbers, and will
be constantly informed about the latest improvements and spare part innovations.
Please bear in mind that if parts other than original DOLMAR spare parts are used,
this will automatically invalidate the DOLMAR product guarantee.
