The care and adjustment of the blades is very important to the
efficient operation of the trimmer and especially to the long
life of the motor.
When resting, it is often a good idea to use the time to oil the
cutting blades.
If a gap exists between the upper and lower blades, follow the
procedure below to adjust them so that they fit more closely
together.
1. Loosen lock nut.
2. Tighten screw 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 is loose enough so
that it may be turned by pressing on it with a finger.
NOTE: Correct blade adjustment can only be achieved on
clean, oiled blades. 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.
