BLADES
• 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) Upper blade (2) Lower blade
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 with
a finger.
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 trim-
mer 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 au-
thorized ZENOAH servicing dealer from which you purchased
your ZENOAH trimmer to have the blades resharpened or re-
placed.
TRANSMISSION
The reduction gears are lubricated by multipurpose,
lithium-based grease in the transmission.
Supply new grease every 25 hours of use or more often
depending on the job condition.
When adding lubricant, use a grease gun to insert lubri-
cant into the three grease nipples located on the trans-
mission.

ANGLE TRANSMISSION
• The reduction gears are lubricated by multipurpose,
lithium-based grease in the angle transmission. Sup-
ply new grease every 25 hours of use or more often
depending on the job condition.
• Remove the cutter holders before installing new
grease to arrange for old grease to exit.
