ADD GASOLINE (See Fig. 9)

•      Fill fuel tank to bottom of tank fi ller neck.  Do not over-

fi ll.  Use fresh, clean, regular unleaded gasoline with 
a minimum of 87 octane.  Do not mix oil with gasoline.  
Purchase fuel in quan ti ties that can be used within 30 
days to assure fuel freshness.

CAUTION:  Wipe off any spilled oil or fuel.  Do not 
store, spill or use gasoline near an open fl ame.

Alcohol blended fuels (called gasohol 
or using ethanol or methanol) can at-
tract moisture which leads to separation 
and for ma tion of acids during storage.  
Acidic gas can damage the fuel sys-
tem of an engine while in storage.  To 
avoid engine problems, the fuel system 
should be emptied before stor age of 30 
days or longer.  Empty the gas tank, 
start the engine and let it run until the 
fuel lines and carburetor are empty.  Use 
fresh fuel next season.  See Storage 
In struc tions for additional information.  
Never use engine or carburetor cleaner 
products in the fuel tank or permanent 
damage may occur.

TO STOP ENGINE 

•      To stop engine, release operator presence con trol bar.

TO START ENGINE (See Fig. 9) 

NOTE: Due to protective coatings on the engine, a small 
amount of smoke may be present during the initial use of 
the product and should be considered normal.

NOTE:  Your engine is equipped with an automatic choke 
system.  No priming or choking is required before starting.

•      To  start  engine,  hold  operator  presence  control  bar 

down to the han dle and pull starter handle quickly. Do 
not allow starter rope to snap back. 

•        Certain types of grass and grass conditions may require 

that an area be mulched a second time to completely 
hide the clippings.  When doing a second cut, mow 
across (perpendicular) to the fi rst cut path.

•      Change your cutting pattern from week to week.  Mow 

north to south one week then change to east to west the 
next week.  This will help prevent matting and graining 
of the lawn.

OPERATION

MOWING TIPS 

CAUTION: Do not use de-thatcher blade 
attachments on your mower.  Such at-
tachments are hazardous, will damage 
your mower and could void your warranty.

•      Under  certain  conditions,  such  as  very  tall  grass,  it 

may be necessary to raise the height of cut to reduce 
pushing effort and to keep from overloading the engine 
and leaving clumps of grass clippings. It may also be 
necessary to reduce ground speed  and/or run the lawn 
mower over the area a second time.

•     For extremely heavy cutting, reduce the width of cut 

by overlapping previously cut path and mow slowly.

•      For better grass bagging and most cutting conditions, 

the engine speed should be set in the fast position.

•         Pores in cloth grass catchers can become fi lled with dirt 

and dust with use and catchers will collect less grass.  
To prevent this, regularly hose catcher off with water 
and let dry before using.

•      Keep top of engine around starter clear and clean of 

grass clippings and chaff.  This will help engine air fl ow 
and extend engine life.

MULCHING MOWING TIPS

IMPORTANT:  FOR BEST PERFORMANCE, KEEP MOWER 
HOUSING FREE OF BUILT-UP GRASS AND TRASH. SEE 
“CLEANING” IN THE MAINTENANCE SECTION OF THIS MANUAL.

•     The special mulching blade will recut the grass clip-

pings many times and reduce them in size so that as 
they fall onto the lawn they will disperse into the grass 
and not be noticed.  Also, the mulched grass will biode-
grade quickly to provide nutrients for the lawn.  Always 
mulch with your highest engine (blade) speed as this 
will provide the best recutting action of the blades.

•        Avoid cutting your lawn when it is wet.  Wet grass tends 

to form clumps and interferes with the mulching action.  
The best time to mow your lawn is the early afternoon.  
At this time the grass has dried, yet the newly cut area 
will not be exposed to direct sunlight.

•      For best results, adjust the lawn mower cutting height 

so that the lawn mower cuts off only the top one-third 
of the grass blades (See Fig. 10).  If the lawn is over-
grown it will be necessary to raise the height of cut to 
reduce pushing effort and to keep from overloading 
the engine and leaving clumps of mulched grass. For 
extremely heavy mulching, reduce your width of cut by 
overlapping previously cut path and mow slowly.

•         Change the oil after every 25 hours of operation or each 

season.  You may need to change the oil more often un-
der dusty, dirty conditions.  See “TO CHANGE ENGINE 
OIL” in the Maintenance section of this manual.
