5.4. Trimming techniques.
If you are not familiar with the trimming,
practice with the machine with the machine
stopped.
5.4.1. Always trim or cut with the engine
running at high speed.
5.4.2. Do not run the machine slowly except
for when warming up before use or cooling
down after use.
5.4.3. Swing the nylon cutting head of the
trimmer horizontally from left to right.
5.4.4. Keep cutting deck parallel with the
ground. Do not tilt the nylon cutting or blade
head during operation.
5.4.5. For correct cutting height trim
a test
area in advance .
5.4.6. Keep nylon cutting or blade head at
the same level for an even depth of cut.
5.4.7. Nylon trimming head is only to be
used for cutting grass.
5.4.8. Metal blade head is only to be used
for brush only.
5.4.9. To prevent overheating NEVER over
cut, instead cut off smaller lengths of grass or
brush. You MUST also remove any tangled
materials – You MUST stop the machine and
remove the HT lead before carrying out this
task.
5.4.10. When trimming around trees trim
slowly making sure that the nylon cord does
not come into contact with the trunk. Walk
around the tree from left to right and
approach grass with the tip of the cutting
nylon cord.
5.4.11. To release more nylon cutting cord
run the machine at full throttle and tap the
nylon cutting head on the grass. The nylon
cord is then released. Any excess cord is cut
off by the trimmer blade mounted on the
guard. When trimming near brick or stone
walls the nylon cord will wear out quicker.
