DRIVE CONTROL ADJUSTMENT
Over time, the drive control system may 
become “loose”, resulting in decreased 
speed.  There is a turnbuckle on the drive 
control housing to increase tension on the 
drive cable.  Pro ceed as follows:
1.   Turn unit off and disconnect spark plug 

wire from spark plug.

2.   Rotate turnbuckle on drive control to 

increase drive speed.

3.   Operate mower to test drive speed.  

Readjust as required.

4.   If condition fails to improve after the 

above steps (forward speed remains 
the same), your drive belt is worn and 
should be re placed.

The operation of any 
lawn mower can result 
in foreign objects thrown 
into the eyes, which can 
result in severe eye dam-

age. Always wear safety glasses or eye 
shields while operating your lawn mower 
or performing any ad just ments or repairs. 
We recommend a standard safety glasses 
or wide vision safety mask worn over 
spectacles.

ENGINE SPEED 
Engine speed was set at the factory for 
optimum performance. It is not adjustable.

 CAUTION:  Federal regulations re quire 

an engine control to be installed on this 
lawn mower in order to minimize the 
risk of blade contact injury. Do not un der 
any circumstances attempt to de feat the 
func tion of the operator con trol. The blade 
turns when the engine is running.
•   Your lawn mower is equipped with an 

operator pres ence control bar which 
requires the operator to be positioned 
behind the lawn mower handle to start 
and operate the lawn mower.

DRIVE CONTROL 
•   Self-propelling is controlled by hold-

 ing the operator presence control bar 
down to the handle and pulling the drive 
control lever rearward to the handle.  
The farther toward the handle the lever 
is pulled, the faster the unit will travel.

•   Forward motion will stop when either 

the operator presence control bar or 
drive control lever are released. To stop 
forward motion without stop ping engine, 
re lease the drive control lever only. Hold 
op er a tor presence control bar down 
against handle to con tin ue mowing 
without self-propelling.

NOTE: If after releasing the drive control 
the mower will not roll backwards, push 
the mower forward slightly to disengage 
drive wheels.
