BLADE (FIGURE 9)
 DANGER: UNPLUG TOOL! WAIT FOR BLADE TO COME TO COMPLETE STOP!
_ The blade, two spacers and hex head nut with conical washer should be attached to your
edger in the order shown. Please check that the blade has been properly mounted before
using your edger. The edger blade has two wear indicators that show when blade needs to
be replaced. When the blade wears to the small hole at each end of the blade it will give only
1/4 in. depth of cut and should be replaced.
Tip: To increase blade life, keep initial cutting depth at minimum and increase depth
setting as blade wears.
TO REMOVE THE BLADE FOR REPLACEMENT:
AADANGER: UNPLUG TOOL! WAIT FOR BLADE TO COME TO COMPLETE STOP!
AADANGER: Blade rotates momentarily after the switch is released.
1. Loosen the hex head nut (9/16 in.). Use a 1 in. wrench on the outer spacer, or a 2 in. x
4 in. wood block between the blade and guard if necessary to hold the blade from
turning.
TO ATTACH NEW BLADE:
2. Ensure inner spacer is on shaft—'flats" in spacer hole must engage with "flats" on shaft.
3. Holding the spacer in place, put the blade on the shaft, as shown (Figure 9).
4. Hold the blade against the spacer and install the outer spacer, again aligning the flats in
the spacer with the flats on the shaft.
5. Install the hex head nut and conical washer, then tighten with a wrench (140 in. pounds).
Note:
Replace hex head nut and conical washer only with identical replacement part, see
Service Information.
SWITCH
To turn tool ON, squeeze the trigger switch. The trigger has been designed so that it is very
easy to hold in the ON position. To turn tool OFF, release the trigger.
OPERATING INSTRUCTIONS
NOTE: The edger is a major appliance and should not be operated simultaneously with other
major appliances on the same household circuit.
/\WARNING: Make sure that other persons and pets are at least 100 feet away.
1. Set cut depth at 1 in. and set edge guide to the down position, refer to Assembly
Instructions.
2. Before starting the edger, line up the tool so the edge guide rests against the edge of the
paved surface (Figure 10). Both rear wheels should be on the paved surface when edging.
Tip: 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 will
require lifting up the edge guide and may require reducing the depth of cut (see Edge
Guide and Depth Adjustment instructions).
3. To avoid kickback of edger, tilt the handle down so the blade is above the ground (Figure 77).
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 elocirica salty ang to paent heoa of the blade chamber. If you must edge
under
conditions that cause the blade chamber to become clogged, release tigger, wait for `
