1. Loosen lock nut (A) as shown in the diagram.
2. Tighten screw (B) fully, and then turn one-third to one half of a rotation backward.
3. While holding onto the screw to keep it in position, tighten the lock nut.
4. Check to make sure that the flat washer (C) is loose enough so that it may be turned by pressing on it.
NOTE!
Screwing in the screw too tightly may make it impossible for the blades to move. Conversely, not screwing in
the screw tightly enough may make the blades of the trimmer feel dull and cause leaves and branches to
become caught in the blades of the trimmer.
QUICK TIP
If the blades become so worn down that it is no longer possible to eliminate the gap between them, you should
contact the dealer from which you purchased your trimmer to have the blades resharpened or replaced.
POLE CHAIN SAW
OILING PORT
Dismount the guide bar and check the oiling port for clogging.
GUIDE BAR
Remove sawdust in the bar groove and the oiling port.
The bar rail should always be a square. Check for wear of the bar rail. Apply a ruler to the bar and the outside
of a cutter. If a gap is observed between them, the rail is normal. Otherwise, the bar rail is worn. Such a bar
needs to be corrected or replaced.
