CARE AND MAINTENANCE

To check the blade balance (Fig. 16b):

Clamp a nail or a screwdriver with a round shank in the horizontal position. Position the blade

so that the nail or round shank of the screwdriver supports the blade through its center hole.

Balance the blade horizontally. If either end of the blade rotates downward, remove some

metal from the heavier (or lower) end until the blade is balanced. It is balanced when neither

end drops.

WARNING

• An unbalanced blade will cause excessive vibration when rotating at high speeds. It may

cause damage to the mower and could break, causing personal injury.

17. Replacing the Wheels

WARNING

• Always remove the battery pack when servicing

or transporting the mower. We recommend

having this task carried out by an after-sales

service provider.

To remove the wheels:

a. Turn the mower on its side with the upper

surface against a wall.

b. Use a at blade screwdriver to pry the dust

cover away from the wheel.

c. Use an adjustable or ½-inch (13mm) wrench

to turn the bolt counterclockwise to loosen it.

d. For front wheels: remove the bolt, the worn

wheel, the wave washer, and at washer from

the wheel axle (Fig. 17a).

e. For rear wheels: remove the bolt, the worn

wheel, the wave washer from the wheel axle

(Fig. 17b).

To mount the wheels:

a. For front wheels: mount the at washer, the

wave washer and the new wheel on the wheel

axle. Note that the round recess of the wheel

must face outward (Fig. 17a).

b. For rear wheels: mount the wave washer

and the new wheel on the wheel axle. Note

that the round recess of the wheel must face

outward (Fig. 17b).

c. Secure the wheel with the bolt by tightening the bolt clockwise.

d. Mount the dust cover onto the wheel and press it into place.
