TIRE AND WHEEL SERVICE

CAUTION: Separation of a tire and rim can

cause an explosion that could cause serious

injury or death.

Check the tires for low pressure, cuts, bubbles,

damaged rims, or missing lug bolts and nuts.

Always use a clip-on chuck with an extension

long enough to allow you to stand on one side

of the wheel while inflating the tires. Do not

stand directly in front of the tire while inflating.

Never weld or heat a tire and wheel assembly.

The heat can cause the air inside of the tire to

expand and result in a tire explosion. Welding

also can structurally weaken or deform the

wheel.

Visually inspect the tires before each use. Do not run the

tires under- or over-inflated which can cause tire damage.

The correct tire pressure for the front tires is 20 p.s.i.

(82.7 kpa) and rear wheels is 12 p.s.i. (137.9 kpa) (see

figure 25).

When reinstalling the wheel after service, be sure to torque

the nuts to 75 ft. Ibs. (101 N-m). Drive 200-250 yards and

then re-torque.

BLADE MAINTENANCE

CAUTION: Before removing the blades, be sure

the engine has stopped and the key has been

removed. The blades may be sharp. Wear gloves

or wrap them in a towel before handling them.

Inspect the blades daily for straightness, sharpness, and

balance. Replace the blades if they are cracked, worn, bent

or out of balance.

NOTE: Keep blades sharp. Mowing with dull blades will

cause poor cut performance. It will also put additional strain

on the engine by slowing the mower cutting speed.

CAUTION: Never try to straighten a blade which

has been bent or try to weld a blade that is

cracked. Always replace with a new blade to

ensure safety.

To sharpen the blades, remove the blades by inserting a

block of wood and turning the blade bolt counter clockwise

(see figure 26).

,_ CAUTION: Always wear safety eye protection

when sharpening the blades.

Be sure to wear a thick glove or wrap the blade in a towel to

protect your hands from being cut. Insert the blades in a vise

and use a mill file or grinder. File the blade along the original

angle until the blade tip is at a 30° angle again.
