TO SHARPEN BLADE

Care should be taken to keep the blade bal- anced. An unbalanced blade will cause

eventual damage to lawn mower or engine. o The blade can be sharpened with a file or

on a grinding wheel. Do not attempt to sharpen while on the mower:

o 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

(if purchased as an accessory)

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

. Check your grass catcher often for darn- age or deterioration. Through normal use it will wear: if catcher needs replac- ing, replace only with a manufacturer approved replacement catcher. Give the lawn mower model number when order- in.

DRI_fE 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, check both front wheels.

o Remove hubcaps, hairpin cotters and washers

o Remove wheels from wheel adjusters.

°Remove any trash or grass cuttings

from inside the dust cover, pinion and/or drive wheel gear teeth.

-Put wheels back in place,

-If after cleaning, the drive wheels do not

turn freely, contact your nearest autho- rized service center:

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 build--up. Clean under the drive cover twice a season.

°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 Texaco

Starplex Premium 1 Grease, Part No. 750355. Do not substitute.

TEMP_ERATUR_ RANGE ANTtCIPAfEID BEFORE NEXT OIL CHANGE

NOTE: Although multi--viscosity oils (5W30, 10W30 etc.) improve starting in

cold weather, these multi--viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid

possible engine damage from running low on oil.

Change the oil after every 25 hours of op- eration or at least once a year if the lawn mower is not used for 25 hours in one year. Check the crankcase oil level before start- ing the engine and after each five (5) hours of continuous use. Tighten oil plug securely each time you check the oil level.
