TO REPLACE DRIVE BELT

1.  Place new drive belt in the belt retainer of the debris 

shield.  Be sure to route belt between belt keepers and 
through slot as shown (See Fig. 21). 

Maintenance, re pair, or re place ment of the emission con-
 trol de vic es and sys tems, which are be ing done at the 
cus tom ers expense, may be performed by any non-road 
engine repair es tab lish ment or individual. Warranty repairs 
must be performed by an authorized engine man u fac tur er's 
service outlet.

Your engine speed has been factory set.  Do not attempt to 
increase engine speed or it may  result in personal injury.  If 
you believe that the engine is running too fast or too slow, 
take your lawn mower to an authorized service center for 
repair and adjustment.

Your carburetor is not adjustable.  If your engine does not 
operate properly due to suspected carburetor problems, 
take your lawn mower to an authorized service center for 
repair and/or adjustment.

IMPORTANT:  NEVER TAMPER WITH THE ENGINE GOVERNOR, 
WHICH IS FACTORY SET FOR PROPER ENGINE SPEED.  
OVER SPEED ING THE ENGINE ABOVE THE FACTORY HIGH 
SPEED SETTING CAN BE DANGEROUS.  IF YOU THINK THE 
ENGINE-GOVERNED HIGH SPEED NEEDS ADJUSTING, 
CONTACT YOUR NEAREST AUTHORIZED SER VICE CEN TER, 
WHICH HAS PROPER EQUIP MENT AND EXPERIENCE TO 
MAKE ANY NEC ES SARY ADJUSTMENTS. 

The handle on your lawn mower has three (3) height posi-
tions - adjust to height that suits you.

• 

Squeeze the bottom ends of lower handle towards each 
other until the pin in handle can be inserted into one 
of the three height adjustment holes.

2.  Route the other end of the new drive belt through hole 

in housing.

3.  Reattach debris shield to housing with screw previ-

ously removed.  Be sure tab of debris shield is in gap 
of housing.

4.  Position blade on the blade adapter aligning the two 

(2) holes in the blade with the raised lugs on the 
adapter.

5.  Be sure the trailing edge of blade (opposite sharp edge) 

is up toward the engine as shown (See Fig. 20).

6.  Install the blade bolt with the lock washer and hardened 

washer into blade adapter and crankshaft.

7.  Use block of wood between blade and lawn mower hous-

ing and tighten the blade bolt, turning clockwise.

• 

The recommended tightening torque is 35-40 ft. lbs.  

IMPORTANT:  Blade bolt is heat treated.  If bolt needs 

replacing, replace only with approved bolt shown in the 

Repair Parts section of this manual.

8.  Return mower to upright position.

9.  Install new drive belt into idler arm assembly, then 

around the drive pulley.  Be sure belt is inside of belt 
keepers (See Fig. 19).

NOTE: Pulling on the drive belt (to install it on the drive 
pulley) will cause the other end of the belt to free itself from 
the debris shield retainer and come into contact with the 
pulley end of the blade adapter.

10.  Reattach drive cable and return spring to the idler arm 

assembly, then reattach drive cable to anchor.
