• 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.
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 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 servicing
dealer from which you purchased your ZENOAH trim-
mer to have the blades resharpened or replaced.
GEAR CASE
• The reduction gears are lubricated by multipurpose,
lithium-based grease in the gear case. Supply new
grease every 25 hours of use or more often depend-
ing on the job condition. When adding lubricant, use
a grease gun to insert lubricant into the three grease
nipples located on the gear case.
TYPE OF LUBRICANT TO BE USED
Always be sure to use #2 lithium heat-resistant lubricant.
