To begin edging, proceed as follows:
1. Move the edger to an area to be edged,
making sure that the left rear wheel is on a
hard surface and the blade is over the area to
be cut. See Figure 3-3.
Figure 3-3
2. With blade control lever in START position,
make a pass along the area to be edged
before proceeding to the next notch. The
further forward the blade depth control lever
is moved, the deeper or lower the blade will
cut into the ground. Several passes may be
necessary to obtain the desired depth of cut.
Do not lower the blade more than one depth
notch at a time without making a pass.
3. For best results, proceed slowly along the path
being edged. Slowly move the edger back and
forth through the cutting area, again making
sure to keep the left rear wheel on the hard
surface and the blade in the cutting path,
close to but not touching the edge of the hard
surface.
4. Once you have finished edging the selected
area, raise the blade control lever back into the
START position, move to the next area to be
edged, and proceed again from Step 1.
Edging Along a Curb (If equipped with Curb
Height Adjustment Lever)
The right, rear wheel of the edger can be lowered
into one of five positions to ease the task of edging
along a curb. To adjust the height of curb wheel,
proceed as follows:
1. Lower the right rear wheel by moving the curb
height adjustment lever slightly to the left. See
Figure 3-4.

2. Pivot the right rear wheel into an applicable
position in relation to the height of the curb to
be edged along.
3. Release the curb height adjustment lever to lock
the wheel in position. See Figure 3-4.
Beveling (IF EQUIPPED)
In order to achieve a bevelled edge, set the bevel
adjustment lever in the first (left hand) or third (right
hand) notch to place the edger blade in position for
beveling. See Figure 3-5. Refer to the Assembly &
Set-Up Section
Right-Hand Position Left-Hand Position

Trenching (IF EQUIPPED)
If your edger comes with a trenching kit, you can
utilize the edger's optional trenching feature in order
to create a wider cutting path for such things as
laying wire for landscape lighting.
WARNING! Disconnect the spark plug
wire and ground against the engine
before performing the following steps.
WARNING! The edger blade is sharp.
Wear leather work gloves to protect your
hands when working around the edger
blade.
1. Use two wrenches (one wrench to prevent the
hex bolt head from spinning and the other to
unthread the flange nut) to remove the flange
nut that secures the edger blade, leaving the
edger blade in place. See Figure 3-6.

2. Install the additional edger blade and flat
washer supplied with your machine. See
Figure 3-6.
3. Secure with the flange nut removed in Step 1.
Use a torque wrench to tighten the flange nut
to between 37 ft lb and 50 ft-lb.
NOTE: Make certain that the drive belt is
seated correctly on the blade spindle and that
it is riding smoothly on the spindle sheaves
and is not pinched between them. Repeat
Steps 1 and 3 to adjust if belt is pinched.
