OPERATING TIPS
1. Check the blade rotation control for correct adjustment. For the
blade(s) to disengage correctly, the adjustment must be cor-
rect.
2. Before you use the unit, check the oil in the engine and add oil
if necessary.
3. If the engine will not start, first make sure the wire is attached
to the spark plug.
4. Make sure all the belts are inside all the belt guides. See the in-
structions on how to remove and install the motion drive and
mower drive belts.
5. Before you make an inspection, adjustment (except for the car-
buretor) or repair, make sure the wire from the spark plug is dis-
connected.
6. For longer life of the battery on electric start models, charge the
battery every three months.
7. Use the speed control pedal to change the ground speed, not
the throttle control.
8. Belt noise can occur when the blade is engaged. This noise is
normal and does not affect the operation of the unit.
MOWING AND BAGGING TIPS
1. For a lawn to look better, check the cutting level of the mower
housing. See “How To Level The Mower Housing” in the Main-
tenance section.
2. For the mower housing to cut level, make sure the tires have
the correct amount of air pressure and use slow ground speeds
when turning.
3. Every time you use the unit, check the blade. If the blade is bent
or damaged, immediately replace the blade. Also, make sure
the nut for the blade is tight.
4. Keep the blade(s) sharpened. Worn blades will cause the ends
of the grass to turn brown.
5. Do not cut or bag grass that is wet. Wet grass will not discharge
correctly. Let the grass dry before cutting.
6. Use the left side of the mower housing to trim near an object.
7. Discharge the cut grass onto the mowed area. The result is a
more even discharge of cut grass.
8. When you mow large areas, start by turning to the right so that
the cut grass will discharge away from shrubs, fences, drive-
ways, etc. After one or two rounds, mow in the opposite direc-
tion making left turns until finished (Figure 13).
9. Use a mowing pattern that eliminates reverse travel as much
as possible.
10. If the grass is very high, cut two times to decrease the load on
the engine. First cut with the mower housing in the highest posi-
tion and then lower the mower housing for the second cut.
11. For better engine performance and an even discharge of the
cut grass, always operate the engine with the throttle in FAST
position.
12. When you use a bagger, operate the engine with the throttle in
FAST position and the speed control pedal pushed 1/3 forward.
13. For better cutting performance and a quality cut, mow with the
speed control pedal pushed 1/3 to 1/2 forward.
14. After each use, clean the bottom and top of the mower housing
for better performance. Also, a clean mower housing will help
prevent a fire.
