• Before cleaning, inspecting, or repairing the unit, make sure that the engine has stopped and is cool.
• Use protective gloves whenever inspecting, removing, sharpening, and installing the blades.
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.
• 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 impos-
sible for the blades to move. Conversely, not screw-
ing 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 authorized ZENOAH servic-
ing dealer from which you purchased your ZENOAH
trimmer to have the blades resharpened or re-
placed.
TRANSMISSION
• The inside of the transmission should be lubricant
using ZENOAH-approved lubricant after every 25
hours of use.
• When adding lubricant, use a grease gun to insert
lubricant into the three grease nipples located on the
transmission.
TYPE OF LUBRICANT TO BE USED
Always be sure to use #2 lithium heat-resistant lubri-
cant.
