You can also try the method illustrated in Figure 24,
especially for the green, 155 mil cord. This not only
holds the cord tight, but also helps the cords cut
better in larger diameter, tough and woody growth.
·
Another method is shown in Figure 25.
Be careful not to move too fast through thick growth. If
there are woody weeds in the material being cut, the
cutting cords may wrap around the stalks they cannot cut
and pull away from the trimmer head. If the cutting
cords can't cut quickly, they may tear from the machine.
Ease the tips into heavy growth.
F
Reminder: The tips of the cutting cords do the
cutting.
Adjusting the Cutting Height
One cutting height adjustment disk is already installed on your machine, just above the Mow-Ball
™
Support. An additional disk is included in your product package, but you can order more. We
recommend you try trimming with one disk before experimenting with additional disks.
The cords will cut approximately 1-1/2" to 2" off the ground with one disk installed. If the cut is
too low or if you're cutting very tall or heavy grass, you may want to try using an additional disk.
Tool Needed:
• Phillips head screwdriver
Caution: An improper installation may cause damage to the bearings. Please follow these
directions carefully.
Caution: Do not tip the machine all the way back on its handlebars unless you first drain the gas
and oil.
