Figure 13

When sharpening the blade, follow the odginal

angle of grind as a guide. It is extremely important

that each cutting edge receives an equal amount of

grinding to prevent an unbalanced blade.

Test the blade by balancing it on a round shaft

screwdriver or a blade balancer as shown in Figure

13.

If the blade is not balanced, remove metal from the

heavy side until it balances evenly.

WARNING: An unbalanced blade will

cause excessive vibration when rotating at

high speeds. It may also cause damage to the

mower and could break, causing personal

injury.

Reinstall the blade as described earlier in this

section making certain to torque the cutting blade to

specifications.

MowerDeck

WARNING: To reduce the risk of electricshock, do not expose the mower to water,

The underside of mower deck should be cleaned after

each use as grass clippings, leaves, dirt and other

debris will accumulate. This accumulation of grass

clippings, etc., is undesirable as it will promote rust and

corrosion.

Remove any buildup of grass and leaves on or

around the motor cover (do not use water). Wipe

the mower clean with a dry cloth occasionally.

If debris is allowed to build up on the underside of

the unit, tilt the mower forward or on its side and

scrape it clean with a suitable tool.

Lubrication

At the beginning and end of each mowing season:

Lubricate the springs on the rear discharge door

with a light oil.

Remove the wheels and lubricate the surface of the

axle bolt and the inner surface of the wheel with

light oil.

SECTION8: OFF-SEASONSTORAGE

The following steps should be taken to prepare the lawn

mower for storage.

Make certain the power supply is disconnected.

Clean mower as instructed in previous section.

Inspect and replace/sharpen blade if required.

Refer to Cutting Blade section on page 13.

Lubricate mower following instructions on page 14.

Store mower in a dry, clean area. Do not store next

to corrosive materials, such as fertilizer and rock

salt.

Wipe extension cord to remove any foreign

substance such as oil or stains. Replace extension

cord if cut or damaged in any way.

Wind cord in a series of equal loops on each side of

your hand to prevent snarling.

Store mower indoors, in a cool, dry place, out of

reach of children. Do not cover lawn mower with a

solid plastic sheet. Any plastic covering traps

moisture around the mower which promote rust and

corrosion.
