screws
• To achieve the highest cutting position, loosen and
remove the nuts on both sides of the roller assembly.
• Place the screw back; pass it through the bottom
hole of the plastic roller bracket and the top hole of
the mower side plate. Fasten nuts on both sides.
Other cutting heights can be obtained by positioning
the bolts through other hole locations.
Mower blade adjustment.
The height of the blades
have been pre-adjusted before been packed.
Misalignment can occur resulting in blades that are
too loose or too tight. If this happens, you will notice
a rough, uneven cut or a hard-pushing mower.
All adjustments are made frlom the rear of the mower.
Each end of the cutting bar can be adjusted separately.
As you follow the instructions below, refer to figure 6
for more information.
• The cutting bar blade (located under the reel) turns
under a pivot. The front screw move the cutter bar
toward the blades.
• Adjusting the screw is a very sensitive procedure,
1/16 of a turn is considered a major adjustment.
• Before tightening one adjusting screw, be sure to
loosen the opposing screw an equal amount.

• Insert a piece of paper between the cutter bar and the
reel blades, and carefully turn the reel blades by hand.
All blades should slice the paper evenly the entire length
of the cutter bar while the reel turns smoothly.
It the mower has a intermittent cut, adjustment should be
made to appropriate side of the blades to attain proper
cutting actions.
Sharpening the cutting blades.
When the mower is
properly lubricated and adjusted, sharpening should not
be necessary for several years.
However, the following steps
will allow you to do the
procedure yourself at relatively
little expense.
• Remove the “E” ring, wheels
and pinion from both sides of
the mower (refer to figure 6).
• Remove both pawls from the
rectangular slots in reel shaft
and reverse their positions
(refer to figure 7).
• Reverse the placement of the
pinion gears.
• Place the left pinion on the
right end of the reel shaft and
the right pinion on the left end
of the reel shaft. Replace the
wheel and “E” rings.
• Spread a thin layer of lapping
compound on the front edge reel blades.
• Adjust the cutter bar so that cutter bar blade has light
but firm contact with the reel blades across the full widht
of the cutter bar (refer to figure 8).
CAUTION:
Do not overtighten
the addjusting screw, as this
could damage the cutter bar.
Both screws must be tight on
the final adjustment.
• Push the mower backward
on a smooth surface (such as a
sidewalk or paved driveway).
Continue to do this until the
reel blades rotate relatively free
and front edge of the cutter bar
blade is polished.
• Remove wheels; reverse points
and pawls so that the beveled edge of the pawl is on the
right.que las cuchillas del cilindro roten libremente y el
borde delantero de la cuchilla de la barra de corte quede
bien pulida.
• Quite las ruedas, invierta los piñones y los trinquetes para
que el borde biselado del trinquete quede a la derecha.
CAUTION:
Clean any grinding compound or debris from the
cutter bar blade, reel blades, pinions and pawls. Lubricate
axle and pinions with a light film of wheelbearing grease
and replace wheels and “E” rings.
NOTE:
It is recommended to use an industrial or valve
lapping compound between 100-240 grit. This is usually
available at an industrial or automotive supply store. If
professional sharpening is required, consult any lawn
mower repair services.
Loosening blades.
The cutting bar blades must be
moved further from the cutting reel.
• Loosen both back screws equal by turning them
counterclockwise.
• Tighten both front screw equally by turning them
clockwise.
