2. Cut a piece of 2x4 wood N-1 (about 2 feet long) (610 mm) to keep blade from

turning while removing flange nut.

3. Turn the mower on its side. Wear gloves and proper eye protection. Be careful of

“GRASS SIDE” on the blade will be facing the ground when the mower is returned to

its normal upright position. After installing blade O-4, place plastic blade insulator

O-3 on blade such that the raised lips on one side engage the edges of the blade.

Then install the blade spacer O-2 so that it sits inside the raised lips on the

other side of the blade insulator. Be sure to align the flats in the hole of the blade

spacer with the flats of the shaft, rotating the blade and blade insulator together as

necessary.

flange nut with the flange against the blade spacer and securely tighten.

KEEP BLADE SHARP FOR BEST MOWER PERFORMANCE. A DULL BLADE DOES

NOT CUT GRASS CLEANLY OR MULCH PROPERLY.

USE PROPER EYE PROTECTION WHILE REMOVING, SHARPENING, AND

INSTALLING BLADE. ENSURE THAT SAFETY KEY AND BATTERY PACK IS

REMOVED.

Sharpening the blade twice during a mowing season is usually sufficient under normal

circumstances. Sand causes the blade to dull quickly. If your lawn has sandy soil, more

frequent sharpening may be required.

REPLACE BENT OR DAMAGED BLADE IMMEDIATELY.

WHEN SHARPENING THE BLADE:

1. Make sure blade remains balanced.

2. Sharpen blade at the original cutting angle.

3. Sharpen cutting edges on both ends of blade, removing equal amounts of material

from both ends.

TO SHARPEN BLADE IN A VISE:

1. Be sure the bail handle is released, the blade has stopped and safety key and battery

pack removed before removing the blade.

2. Remove blade from mower. See instructions for removing and installing blade.

3. Secure blade Q-1 in a vise Q-2.

4. Wear proper eye protection and gloves and be careful not to cut yourself.

5. Carefully file the cutting edges of the blade with a ne tooth le Q-3 or sharpening

stone, maintaining the original cutting edge.

6. Check balance of blade. See instructions for blade balancing.

7. Replace blade on mower and tighten securely.
