User Clothing:

DO NOT operate the mower while wearing
sandals, tennis shoes, sneakers, or shorts.
Always wear long non-baggy pants. Wear high-
top leather work boots with thick, textured
tread, soft-rubber soles at all times. Hard or
smooth soled shoes are too slippery for a good
footing on mower platform. NEVER wear loose-
fitting clothing which could get caught in moving
parts. Wearing safety glasses, ear protection
and safety shoes is advisable and required by
some local ordinances and insurance regula-
tions.

Inspect Mower Before Each Use:

DO NOT use the mower if any parts are not
maintained in good operating condition. Examine
the moving parts prior to each use. Look for
excessive wear, bald or worn tires, cracks in
parts, loose or missing bolts, cotter, linchpin or
“hair” pins and replace before operating the
mower. Make sure all safety equipment pro-
vided with the mower is in good operating order,
including all the warning decals and the required
operator-presence device which stops the
engine and blades when the foot-operated
Operator Presence Control (OPC) switch is
released. (To test the OPC, follow instructions
in the Operating Instructions section of this
manual.) Inspect the two anti-tip rollers and their
respective bolts at the rear of the mower for
tightness and proper operation. Ensure that all
parts of the hand-operated transmission control
system are tight and secure. This is to reduce
the possibility that the mower could have a loss
of control or safety.

Scheduled Mower Maintenance
Safety:

Replace worn tire(s) with less than 3/32" of any
tread groove left. Use tires with the tread pattern
specified by Wright Mfg., Inc. only. Grease all
fittings daily. DO NOT change the engine gover-

nor settings or over-rev the engine contrary to
engine manufacturer specifications. Keep the
Wright mower in good operating condition, and
keep safety devices and shields in place and in
working condition. Keep all nuts, bolts, and
screws tight to be sure the equipment is in safe
working condition. Check the blade mounting
bolts for proper tightness every eight (8) hours of
operation. Check the blades for excessive wear
and sharpness every four to eight (4-8) hours of
operation. Replace excessively worn blades.
Sharpen dull blades. The mower should not be
used after the blades or other part of the mower
strikes a foreign object, until conducting a thor-
ough inspection and any damage is repaired.
See the instructions in the Recommended Main-
tenance section of this manual for other items of
required maintenance.

Work Area Conditions and Inspection:

Prior to operating the unit carefully inspect all
lawn/ground areas where you plan to use the
mower for hidden, hard-to-see objects or un-
even ground that may be hidden in the grass.
Clear the work area of moveable objects such
as wires, rocks, glass, etc. that might be picked
up by the mower and dangerously thrown.
Remove, if possible, or mark the location of all
immovable objects or irregular areas and be
sure not to hit them with any part of the mower,
its deck or the blades. Obstacles such as holes,
abrupt changes in ground contour, tree trunks,
stumps or roots, stub pipes protruding from the
ground, paving edges, etc. in the path of opera-
tion can abruptly turn or stop the mower.  This
could throw you off the mower or into and
possibly over the handle bars causing serious
injury or death. The faster you are moving the
more potential there is for injury. Mow only in
daylight or in good artificial light. Keep away
from drop-offs, the edges of ponds, streams,
pools, etc. especially at the bottom of slopes.
Do not mow when children or others are around.
When the Wright mower is in use, never direct
the grass discharge toward bystanders, traffic,
cars or buildings nor allow anyone near the
machine while in operation. Thrown objects can
pass through glass windows and some walls of
