LAWN MOWER
Always observe safety rules when per- forming any maintenance.
TmRES

*Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage.
DRmVE WHEELS
Check front drive wheels each time before you mow to be sure they move freely.
The wheels not turning freely means trash, grass cuttings, etc. are in the drive wheel area and must be cleaned to free drive wheels.
If necessary to clean the drive wheels, be sure to clean both front wheels.

NOTE: If after cleaning, the drive wheels do not turn freely, contact a Sears or other qualified service center.

TO SHARPEN BLADE
NOTE: We do not recommend sharpening
the blade - but if you do, be sure the blade is balanced.
Care should be taken to keep the blade bal- anced.An unbalanced blade will cause even-
tual damage to lawn mower or engine.
The blade can be sharpened with a file or on a grinding wheel. Do not attempt to sharpen while on the mower.
To check blade balance, drive a nail into a beam or wall. Leave about one inch of
the straight nail exposed. Place center hole of blade over the head of the nail.
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 dam-
age or deterioration. Through normal use it will wear. If catcher needs replac- ing, 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 CASE
To keep your drive system working properly, the gear case and area around the drive should be kept clean and free of trash
The gear case is filled with lubricant to the proper level at the factory. The only time the lubricant needs attention is if service has been performed on the gear case.
@ If lubricant is required, use only Elf Mul-
13
tis EP00. Do not substitute.
