○ A dirty air fi lter
○ Hard running conditions (such as cold weather)
These factors cause deposits on the spark plug electrodes, which
may result in malfunction and starting diffi culties. If the engine
is low on power, diffi cult to start or runs poorly at idling speed,
always check the spark plug fi rst. If the spark plug is dirty, clean it
and check the electrode gap. Re-adjust if necessary. The correct
gap is 0.6 mm. The spark plug should be replaced after about 100
operation hours or earlier if the electrodes are badly eroded.
NOTE
In some areas, local law requires using a resistor spark plug
to suppress ignition signals. If this machine was originally
equipped with resistor spark plug, use same type of spark plug
for replacement.
Angle transmission (Fig. 29)
Check angle transmission or angle gear for grease level about
every 50 hours of operation by removing the grease fi ller plug on
the side of angle transmission.
If no grease can be seen on the fl anks of the gears, fi ll the
transmission with quality lithium based multipurpose grease up to
3/4. Do not completely fi ll the transmission.
Semi-auto cutting head
Nylon line replacement
(1) Remove the case (26) by fi rmly pushing inward the locking tabs
with your thumbs as shown in Fig. 30.
(2) After removing the case, take out the reel and discard the
remaining line.
(3) Fold the new nylon line unevenly in half as shown in picture.
Hook the U-shaped end of the nylon line into the groove (27) on
the center partition of the reel.
Wind both halves of the line on the reel in the same direction,
keeping each half of the line on its own side of the partition.
(Fig. 31)
(4) Push each line into the stopper holes (28), leaving the loose
ends approx. 10 cm in length. (Fig. 32)
(5) Insert both loose ends of the line through the cord guide (29)
when placing the reel in the case. (Fig. 33)
NOTE
When placing a reel in the case, try to line up the stopper holes
(28) with the cord guide (29) for easier line release later.
(6) Place the cover over the case so that the cap locking tabs (30)
on the case meet the long holes (31) on the cover. Then push
the case securely until it clicks into place. (Fig. 34)
(7) The initial cutting line length should be approx. 11–14 cm and
should be equal on both sides. (Fig. 35)
NOTE
When sharpening blade it is important to maintain an original
shape of radius at the base of the tooth to avoid cracking.
Maintenance schedule
Below you will fi nd some general maintenance instructions. For
further information please contact your Tanaka dealer.
Daily maintenance
○ Clean the exterior of the unit.
○ Check that the harness is undamaged.
○ Check the cutting attachment guard for damage or cracks.
Change the guard in case of impacts or cracks.
○ Check that the cutting attachment is properly centred and
without cracks. An off -centre cutting attachment induces heavy
vibrations that may damage the unit.
○ Check that the cutting attachment nut is suffi ciently tightened.
○ Check that nuts and screws are suffi ciently tightened.
○ Check that the unit is undamaged and free of defects.
Weekly maintenance
○ Check the starter, especially the cord and return spring.
○ Clean the exterior of the spark plug.
○ Remove it and check the electrode gap. Adjust it to 0.6 mm, or
change the spark plug.
○ Check that the angle gear is fi lled with grease up to 3/4.
○ Clean the air fi lter.
Monthly maintenance
○ Rinse the fuel tank with gasoline.
○ Clean the exterior of the carburetor and the space around it.
○ Clean the fan and the space around it.
