WARNING: Rotating cutting blade may
throw objects causing personal injury.
Keep area clear of bystanders and do not
operate without guards in place.
Beveling
In order to achieve a bevelled edge, set the bevel
adjustment lever (refer to Figure 8) in the first (left hand)
or third (right hand) notch to place the edger blade in
position for beveling. See Figure 9.
Figure 9
Trenching (models so equipped)
In order to create a wider cutting path for such things as
laying wire for landscape lighting or invisible fences,
you can utilize the edger’s trenching feature (if so
equipped).
NOTE: Edger features vary by model. All edger models
do NOT come equipped for trenching. If your edger was
not purchased equipped to do so, you may purchase
part no. 736-04088 (flat washer) and part no. 781-0748
(triplex edger blade) to utilize this feature.
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.
Working in front of the edger, loosen the flange lock
nut on top of frame, allowing the idler pulley
assembly to pivot slightly out from the frame. See
Figure 10.
With your other hand, carefully reach under the rear
of the unit and remove the belt from around the
engine flywheel pulley. See Figure 10.

Use two wrenches (one wrench to prevent the hex
bolt head from spinning and the other to unthread
the hex lock nut) to remove the hex lock nut and
bell washer that secure the edger blade, leaving the
edger blade in place. See Figure 12.
