TIPS
,_ CAUTION:

blade attachments
on your mower° Such
attachments
are hazardous,
will damage
your mower and could void your warranty_
o Under certain conditions,
such as very
tall grass, it may be necessary
to raise
tile 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 cut-
ting conditions,
the engine
speed should
be set in the FAST position°
o Pores in cloth grass catchers
can
become
filled 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 flow and extend
engine
life.
