User Clothing:

DO NOT operate the mower while wearing sandals, tennis shoes, sneakers, or shorts.

Always wear long non-baggy pants. Wear hightop 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 loosefitting 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 regulations.


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 provided 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-

page 2

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 thorough inspection and any damage is repaired.

See the instructions in the Recommended Maintenance 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 uneven 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 operation 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

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 adjustments, 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.

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

Speeding is dangerous for even an experienced operator. Sudden stops from excessive speed may cause serious injury.

The discharge chute deflector must be installed at all times and in the down position 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, especially 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 pulleys.

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
