9.8.2 GEAR CASE

more often depending on the job condition.
•
Remove the cutter holders before installing
new grease to arrange for old grease to exit.
9.8 MAINTENANCE (LRT-EX ONLY)
9.8.1 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
If the screw is too tight, it may make it impossible for
the blades to move. Also, if the screw is too loose it
may make the blades feel dull and cause leaves and
branches to be caught in the blades of the trimmer.
9.8.2 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 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.
