Semi-auto cutting head
Nylon line replacement
1. Remove the case (37) by fi rmly pushing inward the
locking tabs with your thumbs as shown in Fig. 38.
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
(38) 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. 39)
4. Push each line into the stopper holes (39), leaving the
loose ends approx. 10 cm in length. (Fig. 40)
5. Insert both loose ends of the line through the cord guide
(40) when placing the reel in the case. (Fig. 41)
NOTE
When placing a reel in the case, try to line up the stopper
holes (39) with the cord guide (40) for easier line release
later.
6. Place the cover over the case so that the cap locking
tabs (41) on the case meet the long holes (42) on the
cover. Then push the case securely until it clicks into
place. (Fig. 42)
7. The initial cutting line length should be approx. 11–14 cm
and should be equal on both sides. (Fig. 43)
Blade (Fig. 44)
WARNING
Wear protective gloves when handling or performing
maintenance on the blade.
○ Use a sharp blade. A dull blade is more likely to snag and
thrust.
Replace the fastening nut if it is damaged and hard to
tighten.
○ When replacing blade, purchase one recommended by
Hitachi, with a 25.4 mm (one inch) fi tting hole.
○ In the case of a 3 or 4 tooth blade (43), it can be used on
either side.
○ Use the correct blade for the type of work.
○ When replacing blades, use appropriate tools.
○ When cutting edges become dull, re-sharpen or fi le
as shown in the illustration. Incorrect sharpening may
cause excessive vibration.
○ Discard blades that are bent, warped, cracked, broken
or damaged in any way.
NOTE
When sharpening blade it is important to maintain an
original shape of radius at the base of the tooth to avoid
cracking.
