WARNING

buildings. There is extreme risk of danger from
thrown objects or being cut by the blades of the
mower or being run over if you lose control.
Never operate the mower in an enclosed area
without good, approved ventilation.  Exhaust
fumes are dangerous.

Initial Operating Safety Guidelines:

  Read and understand the warning on the

instrument panel of the mower.

  Keep a firm hold on the stationary handle at

all times.

  Keep both feet on foot platform at all times.
  Know the controls and how to stop quickly.
  Before attempting to start the engine, follow

all starting instructions.

  Look behind before backing up.
  Before leaving the operator’s position for

momentary reasons, turn off the blade
clutch engagement switch, apply the
parking brake. Keep others from coming
near the mower. Get back on the mower
as soon as possible.

  When leaving the Wright mower unattended,

turn off the blade clutch engagement
switch, apply the parking brake, stop the
engine and remove the key. Never leave
the machine unattended on a slope in
case someone disengages the parking
brake which would be hazardous if the
mower were to roll.

  When transporting, driving onto transport

vehicles, into buildings, across parking
lots or otherwise not mowing grass, turn
off the blade clutch engagement switch to
reduce risk of thrown objects and rotating
blade hazard. After coming to a stop
apply the parking brake, stop the engine
and remove the key.

  Before performing any maintenance, repair

service, mowing height or other adjust-
ments, disengage power to blades, apply
the parking brake, stop the engine,
remove ignition key and spark plug wire
from spark plug(s).

  DO NOT allow inexperienced people to

operate the mower until they have read
and understood these safety instructions.

WARNING

Operate the mower at slower speeds
while becoming familiar with it.

  Speeding is dangerous for even an experi-

enced operator.  Sudden stops from
excessive speed may cause serious
injury.

  The discharge chute deflector must be in-

stalled at all times and in the down posi-
tion except that it may be raised when
the grass catcher is completely installed.

  If the mower discharge clogs, turn off the

blade clutch switch, apply the parking
brakes, stop the engine and remove the
key before removing obstruction.

  Keep all shields and covers in place, espe-

cially grass discharge chute deflector, the
blade belt cover, and the pump belt/pulley
cover over the operator’s toe area.

  Keep hands, feet and clothing away from

rotating parts, especially the rear wheels,
blades, engine flywheel, belts and pul-
leys.

  Do not touch engine or muffler while engine is

running or soon after it is stopped. These
areas can be so hot as to cause severe
burns.

  Clean grass, leaves and lubricant spills from

surfaces after use to prevent fire hazard.

  Be alert for traffic when crossing roads or

operating near roadways.

  Before crossing gravel drives, sidewalks or

roads, turn off the blades and wait for
them to stop.

Operation on Slopes:

DO NOT operate on steep slopes. Do not
operate the mower on slopes steeper than you
can feel secure about the traction of the tires
and the stability of the mower. Do not operate
the mower on slopes at all when the grass is
wet. There is a danger of suddenly sliding
sideways or down the hill. On moderate hills
reduce speed and use caution. When operating
on a slope, travel across the grade, whenever
possible, not an up or down pattern. Reduce
speed and exercise extreme caution on slopes
and in sharp turns to prevent tipping or loss of
