THINGS TO KNOW BE FORE YOU ASSEMBLE OR OPERATE YOUR LAWN 
MOW ER

Do I have a side or rear discharge lawn 
mower?
Look for the grass discharge opening on 
your mower.  If the opening is on the right 
side of the mower housing, it is a side 
discharge mower.  If the opening is at the 
back of the mower housing, it is a rear dis-
charge mower.  Only rear discharge lawn 
mowers have a grass catcher in clud ed with 
the mower.  Approved grass catchers for 
side discharge mow ers may be purchased 
from your nearest au tho rized dealer.
Do I have a mulching lawn mower?
Look for the grass discharge opening on 
your mower.  Raise the discharge guard 
(rear door on rear discharge mowers).  If 
the opening is closed off by a plate, then 
your lawn mower is mulcher ready.  To 
convert to a discharging mower, see the 
Operation section of this manual.

SQUEEZE

REAR DEFLECTOR (IF EQUIPPED)
The rear defl ector, attached between the 
rear wheels of your mower, is provided to 
minimize the pos si bil i ty that objects will 
be thrown out of the rear of the mower 
into the operator mowing position.  If the 
defl ector becomes dam aged, it should be 
replaced.

ENGINE

CARBURETOR
The carburetor has been preset at the fac-
tory and ad just ment should not be neces-
sary.  However, minor ad just ment may be 
required to compensate for differences in 
fuel, temperature, altitude or load.  
•   The air fi lter must be assembled to the 

car bu re tor when running engine.

•   Best carburetor adjustment is obtained 

when fuel tank is 1/4 full.

•   In order for the engine to run, the opera-

tor presence control bar must be held 
in the operating position.  There fore, 
and assistant will be required to hold 
the control bar in the operating position 
when making fi nal adjustment to the 
car bu re tor.

See the ADJUSTMENT section of your 
engine manual for further instructions.

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

THROTTLE CONTROL
If it becomes necessary to adjust or re-
place the throttle control, see the ADJUST-
MENT section of your engine man ual.
