Maintenance and care
Checking the nylon line cutting head
1. Make sure each periphery of the 2 retaining pawls of housing
spreads almost fully up to the outer periphery of the respec-
tive cover window.
2. Check mount of cutting head on trimmer and tighten if it is
loose.
3. Check the cutter head for deflection or abnormal noise rotat-
ing it by hand. Deflection or abnormal noise can cause ab-
normal vibration to occur or mount to trimmer to loosen
during rotation which is dangerous.
4. Inspect cover and tap knob for wear. When slot appears on
bottom of the tap knob or when slot appears on cover bottom
close to outlet for nylon line, replace them with new parts
without fail.
5. Check the cutting head for crack or chip. Replace parts that
show any crack or chip with new ones without fail.
