■ BLADES (MA1)
• 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
MA1
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.
(1) Upper blade
(2) Lower blade
• 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.

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 RedMax servicing dealer from
which you purchased your RedMax
trimmer to have the blades resharpened
or replaced.
■ GEAR CASE
The reduction gears are lubricated by
multipurpose, lithium-based grease in the
MA2
gear case. 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 lubricant into the three grease
nipples located on the gear case. (MA2)
TYPE OF LUBRICANT TO BE USED
Always be sure to use #2 lithium
heat-resistant lubricant.
