Lubrication of the blade (28)

Apply a few drops of oil to each slots for the bolts on the
blade (28) every 4 hours of use.
Adjusting the blade (28) [F21]
(FOR THE HEDGE TRIMMER ONLY)
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 locking nut (A).
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 locking 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 impossible for the blades to move while 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.
Oiling port [F22]
(FOR THE POLE PRUNER ONLY)
Dismount the guide bar (31) and check the oiling port
for blockages.
Guide bar (31) [F23]
(FOR THE POLE PRUNER ONLY)
∙ Remove sawdust in the guide bar groove and the
oiling port.
∙ Grease the nose sprocket from the feeding port on
the tip of the guide bar (31).
The guide bar rail should always be a square. Check
for wear of the guide bar rail. Apply a ruler to the guide
bar (31) and the outside of a cutter. If a gap is observed
between them, the rail is normal. Otherwise, the guide
bar rail is worn. Such a bar needs to be corrected or
replaced.
Sprocket (32) [F24]
(FOR THE POLE PRUNER ONLY)
Check for extensive wear, and replace it when the teeth
are worn over 0.3 mm.

keep the saw chain (33) sharp.
Saw chain (33) need to be sharpened when:
∙ Sawdust becomes powder-like.
∙
You need extra force to saw in.
∙ The cut does not go straight.
∙
Vibration increases.
∙ Fuel consumption increases.
WARNING! Be sure to wear chainsaw
gloves.
Before sharpening:
∙
Make sure the saw chain (33) is held securely.
∙ Make sure the engine is stopped.
∙
Use a round file of proper size for your saw chain
(33).
∙ Place your file on the saw chain link and push
straight forward.
∙ After every saw chain link has been set, check the
depth gauge and file it to the correct level.
WARNING! Be sure to round off the
front edge to reduce the chance of
kickback or tie-strap breakage.
Make sure every chain link has the same length and
edge angles.
Transmission [F26]
∙ The reduction gears are lubricated by multipurpose,
lithium-based grease in the angle transmission. Supply
new grease every 25 hours of use or more often
depending on the job condition.
∙ When adding lubricant, insert lubricant into the
grease nipples located on the transmission.
