may tend to clog up at the discharge opening. Release bail handle to turn mower off and remove the safety key. Remove the catcher and shake the grass down to the back end of the bag. Also clean out any grass or debris which may be packed around the discharge opening. Replace the grass catcher.

5. If mower should start to vibrate abnormally, release bail handle to turn mower off and remove safety key. Check immediately for cause. Vibration is a warning of trouble. Do not operate mower until a service check has been made. Refer to troubleshooting guide in manual.

6. ALWAYS Release bail handle to turn mower off AND

REMOVE SAFETY KEY WHEN LEAVING IT UNATTENDED EVEN FOR A SHORT PERIOD OF TIME.

The following suggestions will help you to obtain optimum run time from your cordless mower:

1. Slow down in areas where the grass is especially long or thick.

2. Avoid mowing when the grass is wet from rain or dew-soaked.

3. Cut your lawn frequently, especially during high growth periods.

NOTE: It is recommended that your mower be recharged after use to prolong the battery life. Frequent charging will not harm your battery, and will ensure that the battery is fully charged and ready for its next use. Storing battery not fully charged will shorten battery life.

REMOVING AND INSTALLING BLADE

DANGER: Risk of injury. When reassembling the blade system, ensure each part is reinstalled correctly, as described below. Improper assembly of the blade or other parts of the blade system may cause serious injury.

1.WARNING: release bail handle to turn mower off, WAIT FOR THE BLADE TO STOP, AND REMOVE SAFETY KEY and battery pack.

2.Cut a piece of 2x4 wood (26) (about 2 feet long) (610 mm) to keep blade from turning while removing bolt (27).

3.Wear gloves and proper eye protection. Turn the mower on its side. Be careful of sharp edges of blade. Position wood and unscrew bolt with 13mm wrench (28) as shown in Figure V.

4.Remove bolt and washer (29). Note the orientation of each part as you remove it. Pull off blade (30), blade insulator (31), and fan (32) as shown in Figure X. Examine all pieces for damage and replace if necessary.

5.To reassemble, slide the fan (32) onto the mower with the blades of the fan facing the mower (far right picture in Figure X), then slide the blade insulator on with the D-shaped posts facing out away from the mower and fan. The blade can only be attached to the insulator in one direction. Line up the D-shaped holes of the blade with the D-shaped posts of the insulator, ensuring the writing on the blade faces out away from the mower and insulator.

6.To tighten firmly, position the piece of wood as shown in Figure W to keep the blade from turning. Slide the bolt and washer through all other pieces and securely tighten with the wrench.

BLADE SHARPENING

KEEP BLADE SHARP FOR BEST MOWER PERFORMANCE. A DULL BLADE DOES NOT CUT GRASS CLEANLY.

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: (Figure Y)

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 (30) in a vise (33).

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 fine tooth file (34)

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.

BLADE BALANCING (Figure Z)

Check balance of the blade (30) by placing center hole in the blade over a nail or round shank screwdriver (35), clamped horizontally in a vise (33). If either end of the blade rotates downward, file that end. Blade is properly balanced when neither end drops.

Lubrication

No lubrication is necessary. Do not oil the wheels. They have plastic bearing surfaces which require no lubrication.

Cleaning

Release bail handle (3) to turn mower off, let the blade come to a stop and then remove safety key. Use only mild soap and a damp cloth to clean the mower. Clean out any clippings which may have accumulated on the underside of the deck. After several uses, check all exposed fasteners for tightness.

PREVENTING CORROSION

Fertilizers and other garden chemicals contain agents which greatly accelerate the corrosion of metals. If you mow in areas where fertilizers or chemicals have been used, the mower should be cleaned immediately afterward as follows: (1) Release bail handle (3) to turn mower off and unplug mower. Wipe all exposed parts with a damp cloth.
