MAINTENANCE AND REPAIR INSTRUCTIONS

INSTALLING A PREWOUND REEL

1.Hold the outer spool with one hand and unscrew the Bump Knob™ counterclockwise (Fig. 21, Pg 17). Inspect the bolt inside the Bump Knob™ to make sure it moves freely. Replace the Bump Knob™

if damaged.

2.Remove the old inner reel from the outer spool (Fig. 22, Pg. 17).

3.Remove the spring from the old inner reel (Fig. 22, Pg. 17).

4.Use a clean cloth to clean the spring, shaft, and inner surface of the outer spool (Fig. 23, Pg. 17).

5.Place the spring in the new inner reel. Insert the ends of the line through the eyelets in the outer spool (Fig. 28).

6.Place the new inner reel inside the outer spool. Push the inner reel and outer spool together. While holding the inner reel and outer spool, grasp the ends and pull firmly to release the line from the holding slots in the spool.

NOTE: The spring must be assembled on the inner reel before reassembling the cutting attachment.

7.Hold the inner reel in place and install the Bump Knob™ by turning clockwise. Tighten securely.

EDGER BLADE REPLACEMENT

WARNING: To avoid serious personal injury, always wear gloves while handling, removing or installing the blade.

WARNING: The gear housing gets hot after long periods of use. To avoid serious personal injury, do not touch the housing until it has cooled.

1.Line up the hole in output shaft with the locking rod slot. Insert the locking rod through the slot into the output shaft hole (Fig. 29).

2.While holding the locking rod, loosen the nut on the blade by turning it clockwise with a 5/8 inch wrench (Fig. 30). Remove the nut, retaining washer and blade. Keep the nut and blade retainer for installation.

3.Install the new blade, blade retainer, and nut

(Fig. 31). Insert the locking rod through the slot into the output shaft hole. Make sure that the blade stays flat and centered against the output shaft while tightening the lock nut counterclockwise (Fig. 32).

4.If you have a torque wrench, tighten the nut to

325-335 in.•lbs (37-38 N•m), while holding the locking rod in the slot.

If you do not have a torque wrench, hold the locking rod in the slot. Rotate the nut counterclockwise with a 5/8 inch closed-ended or socket wrench, until the nut presses against the washer and the blade is snug. Make sure the blade assembly is installed correctly, then rotate the nut an additional 1/4-1/2 turn (Fig. 32).

5.Remove the locking rod.

WARNING: Verify the blade is flat against the output shaft after the nut is tightened. If the blade is off-center, the unit will be damaged by vibration, and the blade may fly off, which can cause serious personal injury.
