D. Blade Adjustment
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 engine.
When refilling the tank or 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 as show in the diagram.
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.
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.
WARNING – DANGER
KEEP HANDS AWAY FROM THE BLADES WHILE
SERVICING THE HEDGE TRIMMER. BE SURE
TRIMMER IS SECURED AND BLADES ARE
GUARDED WHILE MAKING ADJUSTMENTS.
E. Notes
WARNING – DANGER
SWITCH OFF THE ENGINE BEFORE LUBRICATING
OR ADJUSTING THE BLADES.
