9.2.8 Gear Lubrication
Check the grease level about every 25 operating hours.
- Rotate the locking screw with a suitable screwdriver.
- If no grease can be seen any more on the screw,
fill approx. 5 g of grease (DIY market) in the gearbox
housing and seal the opening again.
Make sure that the gearbox housing is never completely
filled with grease.
9.2.9 Carburetor Setting
Ex factory the carburetor has been set for optimum
performance. If an improved setting is necessary, please
contact a specialist workshop.
Since these requirements can be fulfilled only with
sufficient and regular training:
• Use a file holder
A file holder must be used while sharpening the saw
chain by hand. The correct filing angle marked thereon.
• Hold the file horizontally (at right angles to the guide
rail) and file according to the angle mark on the file
holder. Support the file holder on the top plate and the
depth gauge.
• File the blade always from the inside to the outside.
• The file sharpens only in forward motion. Lift it up
during the reverse motion.
• Touch the retaining straps and the dynamic parts not
with the file.
• Turn the file regularly to avoid a one-sided wear.
• Take a piece of hard wood to remove ridges from the
cutting edges.
All blades must have the same length, otherwise they
will be of uneven height. Thus, the chain does not run
smoothly and it increases the risk of getting broken.
