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 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
gearcase.
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)
