n The operator is responsible for safe opera-
tion on slopes. Only the operator can
determine the stability of the machine on a
given slope based on existing conditions
like: machine speed and direction, slope
variation, slipperiness, drop-offs, holes,
obstacles, etc.
nn
nn
n
To determine stability on a slope, start at
the bottom and try to drive the machine up
the slope slowly. If you cannot drive up
the slope or if you feel uneasy on it, do not
operate on it.
nn
nn
n Always start mowing at the bottom of
slopes. Traveling up slopes, this machine
has more traction traveling in reverse than
forward. Be careful on slopes to avoid
driving into a position where there is not
enough traction to enable driving out or
stopping.
nn
nn
n Tires may lose traction on slopes even
though the brakes are functioning properly.
nn
nn
n Avoid sudden stops and deceleration when
traveling forward downhill as mower may
tip forwards.
nn
nn
n Do not mow slopes when grass is wet be-
cause slippery conditions will reduce
traction and braking which in turn affects
steering.
nn
nn
n Use caution when making turns. Slow the
mower down before making sharp turns.
Unit can spin very rapidly by positioning
one lever too much ahead or behind the
other.
nn
nn
n Look around you to be sure the area is
clear before turning or backing up.
nn
nn
n Avoid starting or stopping on a slope. If
tires lose traction, disengage the blades
and proceed slowly straight down the
slope.
nn
nn
n Keep all movement on slopes slow and
gradual. Do not make sudden changes in
speed or direction.
nn
nn
n Pass diagonally through sharp dips and
avoid sharp drops.
nn
nn
n Follow manufacturer’s recommendation
for counterweights for added stability
when operating on slopes or using front or
rear mounted attachments. Remove
If the engine does not start within 10
seconds after the starter is engaged,
stop cranking the engine and wait for 30
seconds. Repeat starting sequence
(including the preheating sequence).
Also, if the engine will not start after
refueling or after setting for a
prolonged period, refer to bleeding fuel
lines in the “Engine Troubleshooting”
section of this manual. Never allow the
starter motor to run continuously for
more than 30 seconds. Be sure to warm
engine up regardless of season.
Loading an insufficiently warmed up
engine will shorten its service life.
COLD WEATHER STARTING TIPS
Use proper viscosity oil for temperature expected
(refer to “Engine Manual”).
Set throttle half open.
A warm battery has better starting capacity than
a cold one.
Use fresh winter grade fuel. It is better for winter
starting than leftover summer grade fuel.
UNEVEN TERRAIN
Be careful when operating machine on
uneven ground.
Do not operate on steep slopes.
Operation on a steep slope could cause
loss of control, machine to overturn and
personal injury or death.
nn
nn
n Do not operate on steep slopes. This ma-
chine was not specifically designed to
operate on steep slopes.
