BEFORE STARTING
ENGINE
e
t
Fill engine with oil. (See engine manual for proper
procedure and requirements)
Add gasoline. Fill fuel tank using fresh clean
unleaded gasoline. (See tractor manual for safe
filling procedure and storage instructions)
CAUTION:
Fill to bottom of fuel tank filler neck, Do
not overfill, Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near open flame.
TO START ENGINE
CAUTION;
Keep the blade clutch lever in
"Disengaged"
position when starting
engine
Make sure spark plug wire is properly connected.
Place choke control in "CHOKE"
position if the
engine is cold. A warm engine may not require
choking to start.
,,
Move engine throttle to full position.
Grasp starter handle with one hand.
Puit rope out
slowly until engine reaches start of compression
cycle (rope will pull slightly harder at this point)
Pull roper with a rapid, continuous,
full arm stroke.
Keep a firm grip on starter handle and let rope
rewind slowly.
Do not let starter handle snap back
against starter.
When engine starts move choke to open position.
Allow engine to warm up for a few minutes before
engaging
blades.
NOTE:
If at a high altitude (above 3000 feet) or in cold
temperatures
(below 32°F), the carburetor
fuel mixture
may need to be adjusted
for best performance.
(See
Service and Adjustments
section of the engine manual.
BREAKING IN YOUR MOWER
Break in your belts, pulleys, and engine before you
actually begin mowing.
Start engine, engage blade control to start blades
rotating and allow blades to rotate for approximately
five minutes to break in mower and engine.
CAUTION:
Check area under and around mower for
any objects that could be thrown from
under mower. Make sure that mower
discharge area is clear.
MOWING PROCEDURES
CAUTION:
Tragic accidents
can occur if the
operator is not alert to the presence of
children. Children are often attracted to
the machine and the mowing activity.
NEVER assume that children wilt remain
where you last saw them.
CAUTION:
,_
NEVER carry children. They may fall off
and be seriously
injured or interfere with
safe operation.
IMPORTANT:
Avoid prolonged
mowing of ditches with
slopes greater than 15 degrees. Small engines become
starved for oil at angles greater than 15 degrees and
should only be used for brief periods on such slopes. Be
sure the engine is tilled to the maximum
oil level when
mowing on slopes.
Mowing should be started with tractor in low gear
and speed increased only as mowing conditions will
safely permit.
Mower will perform at its best when engine throttle is
set for full throttle.
You will obtain better mowing results in grassy areas
if they are mowed when the grass is approximately
4" to 5" maximum height. While your mower will cut
grass taller than 5", you will notice a substantial
increase
in engine power required and some change
in the finished appearance
of the area mowed.
-
Mowing conditions
will vary from p_ace to place,
including
the types of grass which are being mowed,
such as fine stalk, coarse stalk, and dense or sparse
grasses, When mowing tall grass you may find that
certain grasses may be pressed downward
under
the wheels so that they will not mow properly. If
this condition exists you may have to mow the area
twice, the first mowing with the mower raised and the
second mowing at the desired height. If it is practical,
you will achieve better results if the second mowing is
at right angle to the previous mowing.
Do not mow grass when it is wet. Wet grass wilt plug
mower and leave undesirable
clumps. Allow grass to
dry before mowing.
°
Always operate mower engine at full throttle when
mowing to assure better mowing performance
and
proper discharge
of material. Regulate ground speed
by selecting a gear low enough to give the best
cutting performance
and quality of cut.
When operating
any attachment,
select a ground
speed that will suit the terrain and give the best
performance
for the attachment
being used.
When mowing slopes, always mow them up and
down at slow speed. Never mow across slopes. Refer
to Slope Operation on page 3 and to the Slope Guide
on page 23.
