Always observe safety rules when per-
forming any main te nance.
IMPORTANT: Remove battery from mow-
er before servicing, cleaning or removing 
material from lawn mower.

TIRES
•   Keep tires free of gasoline, oil, or insect 

control chemi cals which can harm rub-
ber.

•   Avoid stumps, stones, deep ruts, sharp 

objects and other hazards that may 
cause tire damage.

BLADE CARE
For best results, blade must be kept 
sharp.  Re place a bent or dam aged blade.

  CAUTION:  

Use only a replacement 

blade approved by the manufacturer of 
your mower. Using a blade not approved 
by the manufacturer of your mower is haz-
ardous, could damage your mower and 
void your warranty.

TO REMOVE BLADE
1.   Use a wood block between blade and 

mower hous ing to prevent blade from 
turning when re mov ing blade nut.

NOTE:  Protect your hands with gloves 
and/or wrap blade with heavy cloth.
2.   Remove blade nut by turning counter-

clockwise. 

3.   Remove blade and attaching hardware 

(nut, square wash er, insulator wash er).

•   The recommended tightening torque is 

35-40 ft. lbs.  

TO SHARPEN BLADE
NOTE:  We do not recommend sharp-
 en ing blade.  An un bal anced blade will 
cause eventual damage to lawn mower or 
motor. 

DRIVE WHEELS 
Check rear drive wheels each time you 
mow to be sure they move freely.  The 
wheels not turning freely means trash, 
grass cuttings, etc., may be inside the 
drive wheel and dust cover area and must 
be cleaned out to free drive wheels.
If necessary to clean the drive wheels, 
check both rear wheels.

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.

•   The gear case is fi lled 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.

  WARNING:  To reduce the risk of 

electric shock, do not expose the mower 
to water.
IMPORTANT:  For best performance, 
keep mower housing free of grass build-up 
and trash. Clean the underside of your 
mower after each use.
•   Clean the underside of your lawn mower 

by scraping to remove buildup of grass 
and trash.

•   Clean motor cover often to keep trash 

from accumulating. 

•   Keep fi nished surfaces and wheels free 

of all gasoline, oil, etc.

GRASS CATCHER
Grass catcher may be hosed with water 
but must be dry when used.

 CAUTION:  Under nor mal usage, the 

catch er material is subject to de te ri o ra tion 
and wear and should therefore be 
checked to ensure compliance with 
origi nal manufacturer specifi cations.

TO REPLACE BLADE 
1.   Be sure the trailing edge of blade (op-

posite sharp edge) is up toward the 
motor.

2.   Install the square washer and insulated 

washer; secure with blade nut.

3.   Use block of wood between blade and 

lawn mower housing and tighten the 
blade nut, turning clockwise.
