Tool cleaning and maintenance
7. TOOL CLEANING AND MAINTENANCE
Cleaning the chainsaw body
Keep the chainsaw body clean. When cleaning, use a soft cloth soaked in a soap water. Use this cloth to carefully
clean the chainsaw body.
Guide bar maintenance
Most problems with the guide bar occur as a result of uneven wear and tear. Uneven wear and tear occurs
mostly due to incorrect chain sharpening and incorrect adjustment of the raker. If the bar is worn out
unevenly, the guiding groove is getting wider (See Figure). Consequently, it results in chain rattling and rivets
falling off. It is impossible to make straight cuts with the saw. In such case replace the guide bar by a new
one.
Before chain sharpening, always check the state of the guide bar. Using worn out or damaged guide bar is
very dangerous. Using worn out or damaged guide bar will result in chain damage. Cutting using such tool
will also be significantly more difficult and laborious.

Regular maintenance of the guide bar
Dismantle the guide bar (19) from the chainsaw body.
Regularly remove wood dust from the guide bar groove.
While cleaning, use a scraper (29) or a wire (see Fig. 13).
At the end of each working day, clean the oil grooves (30).
Remove burr from the sides of the bar (31). Grind in the
side edges using a flat file (32).
Replace the guide bar, if:
• it is bent or cracked
• its groove is severely damaged or worn out
Note:
When replacing the guide bar, follow the
instructions specified in the Chapter Spare parts and
accessories. Correct bar type is available in the List of
Parts.
