2. Check the nylon cutting head carefully before each use.
   If you notice any of following, replace the worn or damaged parts with new ones immediately (Fig. 19): Dents appear on the knob head.
   The housing (cover) is damaged or cracked.
   The “Limit marks (notches)” on the cover have disappeared.

3. Wear appropriate clothing and protectors.

4. Always stop the engine before inspecting the cutting head BF4 or replacing the nylon cord.

5. Do not allow anyone near the operation area. The cutters might send stones or debris flying, possibly harming bystanders.

6. Never use the cutting head BF4 on tools with a cutter head speed higher than 10,000 RPM.

Installation
See page 5 (Mounting the nylon cutting head)
Operation

1. Increase the cutter head speed to approx. 6,000 RPM. Low speed (under 4,000 RPM) causes inefficient cutting. Use the tip of the nylon cord (shaded area shown in Fig. 20) for more effective cutting.
2. When the nylon cord wears down (becomes short), decrease the engine speed to under 4,000 RPM and bump the knob of the nylon cutting head against the ground to feed out the nylon cord (Fig. 21).

Parts Breakdown

Replacing the nylon cord

1. Press the housing latches inward to lift off the cover; then remove the spool (Fig. 23).
2. Run the new nylon cord through the hole in the center of the spool, and pass one end of the cord through the notch into the other side of the spool. Allow one end of the cord to extend about 3″ (80 mm) further than the other end (Fig. 24). ‘
3. Wind both ends firmly around the spool in the direction of the head rotation (Fig. 25).
4. Wind all but about 4″ (100 mm) to 6 (150 mm) of the cord, leaving the ends temporarily hooked through a notch on the side of the spool (Fig. 26).
5. Mount the spool in the housing so that the grooves and protrusions on the spool are aligned with those in the housing.
6. Unhook the ends of the cord from their temporary position and feed the cords out through the eyelets in the side of the housing (Fig. 27).
7. Align the protrusions on the underside of the cover with the slots of the eyelets. Then push the cover firmly onto the housing to secure it (Fig. 28).
