Usage
1. Set cut depth at 1" (2.5 cm)", refer to Assembly and
Adjustments
Instructions.
2. Before starting the edger, line up the tool so the edge
guide rests against the edge of the paved surface. The
wheel should be on the paved surface when edging.
nOTE: When there is heavy overgrowth of grass over
the paved surface it may drag on the guard. An initial cut
may be required with the edger on the grass side. This
may require reducing the depth of cut (refer to Cut Depth
Adjustment instructions).
3. To avoid kickback of edger, tilt the handle down so the
blade is above the ground.
4. Turn switch ON and allow blade to spin without
moving tool.
5. Slowly lift the handle to lower the blade, finding the edge
of the paved surface and start edging. Then move tool
forward slowly along edge of paved surface, keeping the
edge guide pressed lightly against the pavement edge.
‑ For the first edging each season, it is best to move
forward slowly because grass is thickest then.
Subsequent edging will be completed more rapidly.
If the tool slows down, back it up an inch or two
until the blade comes up to normal speed. During
edging some sparks may be generated from hitting
stones. This is normal. Do not attempt to edge when
the grass or soil is wet or moist—for electrical safety
and to prevent clogging of the blade chamber. If you
must edge under conditions that cause the blade
chamber to become clogged, release trigger, wait
for blade to come to complete stop. Remove battery
pack and remove clogged material with a stick. To
continue to operate the tool in a clogged condition
will seriously overload the motor.
CAUTION: Do not attempt to unclog the blade
chamber by dropping or tapping the tool on the
ground. This can damage the unit. Keep hands clear of
edge guide and blade when cleaning as these wear to
a very sharp point during edging.
WARNING:
Hold the tool using only the designated
gripping surfaces: The powerhead handle and the
auxiliary handle.
WARNING: Do not use the pole as a gripping surface.
Proper hand position requires one hand on the powerhead
handle
13 and one hand on the auxiliary handle 14 .
Proper Hand Position (Fig. F)
WARNING:
To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown.
WARNING:
To reduce the risk of serious personal
injury,
ALWAYS
hold securely in anticipation of a
sudden reaction.
OPERATION
WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories.
An
accidental start‑up can cause injury.
Edge Guide (Fig. E)
The edge guide is useful for cutting a straight path
along sidewalks.
Cut Depth Adjustment (Fig. A, D)
WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories, or prior to
cleaning. An accidental start‑up can cause injury.
The front wheel can be adjusted to allow a deeper or
shallower cut, and to increase the life of the blade.
1. Wait for blade to come to complete stop.
2. Remove battery.
3. Loosen the cut depth knob
2 .
4. Slide the wheel up or down to the desired height.
nOTE:
Lowering the wheel will decrease the cutting
depth. Rasing the wheel will increase the cutting depth.
The recommend depth for edging is 1" (2.5 cm).
nOTE:
Thick overgrowth may drag on the guard. Reduce
the cut depth to the minimum to help reduce this effect.
5. Tighten knob firmly.
Removing the Cutting Blade
1. Align the shaft bushing hole 15 with the locking rod
slot 16 and insert a screwdriver (not supplied) into the
bushing hole. Hold the screwdriver in position.
2. While holding the screwdriver, remove the flange nut 12
by turning it counterclockwise with a 13 mm wrench
(not supplied) as shown in Fig. C
3. Remove the blade spacer 11 and the blade 1 as shown
in Fig. C. Examine all pieces for damage and replace
if necessary.
Installing the New Cutting Blade
1. Install new blade 1 on shoulder of the blade cutter shaft
bushing 17 as shown in Fig. C.
2. Align the shaft bushing hole 15 with the locking rod
slot 16 and insert a screwdriver into the bushing hole.
3. Hold the screwdriver in position.
4. Install the blade spacer
11 on the blade so that the wide
flat side faces the blade.
5. Install flange nut 12 with the flange against the blade
spacer 11 and securely tighten with a 13 mm wrench
(not supplied).
6. Tighten nut counterclockwise against the blade while
holding the locking rod:
‑ If using a torque wrench and an 13 mm socket
tighten to: 325 ‑335 in lb, 27 ‑ 28 ft. lb, 37 ‑ 38 Nm.
‑ Without a torque wrench, use a 13 mm closed‑end
or socket wrench, turning the nut until the blade
retainer is snug against the shaft bushing. Ensure that
the blade is installed correctly, then rotate the nut an
additional 1/4 to 1/2 turn counterclockwise.
7. Remove the screwdriver from the locking rod slot 16 .
