add fuel, when the engine is hot. Never operate the unit
without the fuel cap securely in place. Loosen the fuel
tank cap slowly to relieve any pressure in the tank.

outdoors where there are no sparks or flames. Slowly
remove the fuel cap only after stopping engine. Do not
smoke while fueling or mixing fuel. Wipe up any spilled
fuel from the unit immediately.
• Avoid creating a source of ignition for spilled fuel. Do
not start the engine until fuel vapors dissipate.

in line voltage resulting in loss of power and
overheating. See the operator’s manual for the unit that
will power this add-on for the recommended cord size.
• Inspect all extension cords and the unit power connection
periodically. Look closely for deterioration, cuts or cracks
in the insulation. Also inspect the connections for damage.
Replace the cords if any defects or damage appear.

HOLDING THE UNIT WITH EDGER ADD-ON
Before operating the unit, stand in the operating position
(Figs. 4 & 5). Check for the following:
• The operator is wearing eye protection and proper
clothing.
• The right arm is slightly bent, and the hand is holding
the shaft grip.
• The left arm is straight, and the hand is holding the
handle.
• The unit is at waist level.
• The edger wheel adjusted for proper cut depth and
edger positioned as shown in Figs. 4 or 5.
ADJUSTING EDGER CUTTING DEPTH
1. Loosen the adjustment knob above the wheel
(Fig 6).
2. Slide the wheel to the desired position.
• Raising the wheel increases the cutting depth.
• Lowering the wheel decreases the cutting depth.
3. Tighten the adjustment knob securely.
TIPS FOR BEST EDGING RESULTS
• Keep the cutting attachment perpendicular to the
ground.
• Do not force the edger. Edge the first time at a lesser
depth,(No more than 1/2” depth cut per pass), then do
the area again with a deeper setting.
• Walk the edger at a slow, even pace
• Check the blade condition, as it wears it becomes
smaller, reducing the cutting depth performance.
Replace with a new blade as required.
