■ 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.

(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)
