7. Return the orange vinyl plug to the bearing housing. This will keep out dirt and debris and
ensure the long life of the bearings. Do not put oil or grease in the hole.
It is possible to use up to three cutting height adjustment disks. Using a third disk will also require
purchase of a longer bolt (Part #114641).
Wagner Anti-Wrap Device
The Wagner Anti-Wrap Device was designed
to reduce the amount of grass wrapping
around the bearing housing shaft. It consists
of the trimmer head plate, which has a "vane"
welded to the shaft, and a bracket that fits
around the shaft (Figure 29).
To remove the Anti-Wrap Device bracket:
1. Follow the instructions for removing the
Mow-Ball
™
Support on page 27.
2. Remove the front bearing housing bolt
which mounts the upper part of the
bracket to the frame (Figure 29).
3. Slide the bracket off the bearing housing. You may need to tap the bracket to get it off.
Heavy Growth
Take your time in heavy growth. If the machine can't do it all in one pass, overlap half of the cutting
swath. If the grass is very thick and heavy, try raising the trimmer head off the ground a few inches
by pushing down on the handlebar. Cut the material at this height, and then make a second pass with
the Mow-Ball
™
Support on the ground (Figure 30).
EASE the DR

TRIMMER/MOWER ™ into denser growth. If the material is too tough or woody
and can't be cut, the cutting cords will wrap around it, wear down or even break off.
Sometimes, growth is so heavy that it can't be mowed in rows. A back and forth "vacuum cleaner"
motion often works better when tackling really tough material.
