MAINTENANCE

•To check blade balance, you will need a 5/8" diameter steel bolt, pin, or a cone balancer. (When using a cone balancer, follow the instructions supplied with balancer.)

NOTE: Do not use a nail for balancing blade. The lobes of the center hole may appear to be centered, but are not.

•Slide blade on to an unthreaded portion of the steel bolt or pin and hold the bolt or pin parallel with the ground. If blade is balanced, it should remain in a horizontal position. If either end of the blade moves downward, sharpen the heavy end until the blade is balanced.

GRASS CATCHER

•The grass catcher may be hosed with water, but must be dry when used.

•Check your grass catcher often for damage or dete- rioration. Through normal use it will wear. If catcher needs replacing, replace only with approved replace- ment catcher shown in the Repair Parts section of this manual. Give the lawn mower model number when ordering.

GEAR CASES

•To keep your drive system working properly, the gear cases and area around the drive should be kept clean and free of trash build-up. Clean under the drive cover twice a season.

•The gear cases are filled with lubricant to the proper level at the factory. The only time the lubricant needs atten- tion is if service has been performed on the gear case.
