4. Other cutting heights are achieved by moving the
adjustment levers to the settings between the highest and
lowest positions.
Ensuring a Clean Cut
m
WARNING!
The steel blades are extremely sharp.
To avoid injury, do not touch the blades while making
adjustments.
NOTE: Although the blades are pre-adjusted prior to leaving
the factory, it is recommended that the adjustment be verified
prior to first use.
NOTE: Vibrations during shipping can cause blade
misalignment, which often causes the blades to become too
loose or too tight. This will result in a rough, uneven cut, or
make the mower difficult to push (Fig. 5).
1. To verify proper blade alignment, place the mower on a
flat surface. Remove the handles and
turn the mower reel
upside down to expose the cutting bar.
2. Insert a sheet of paper between the blade reel and cutting
bar, then slowly turn the wheel by hand (Fig. 6).
3. All the blades should slice the paper evenly along the
entire length of the cutting bar while the reel is turned
smoothly.
4. If the mower cuts the paper intermittently, adjustment
should be made to the appropriate side of the blades to
achieve optimal cutting performance.
Adjusting the Mower Blades
1. Each end of the cutting bar can be adjusted separately.
2. The cutting bar blade, which is located under the reel, is
able to pivot. The two adjustment nuts located at the back
of the mower move the cutting bar away from the blades
when they are turned counterclockwise, and closer to the
blades when they are turned clockwise (Fig. 7).

WARNING!
Do not overtighten the adjustment screws
as this could damage the cutting bar. Both screws must be
tight on final adjustment.
