WARNING
PRE-DELIVERY SERVICE OF MOWER BY DEALER
Before proceeding with the Pre-Delivery Service of your mower,
please read the safety instructions manual in its entirety. Only
The Wright Mower is shipped completely assembled and has been adjusted and tested at the factory.
However, due to the jostling of the shipping process and the delivery time lapse, the following items need to
be repeated again before starting the mower. After you have uncrated the mower, follow these procedures in
the order indicated:
Inspect the mower for any damage, unusual conditions or missing parts.
Inspect the mower for all of its decals, especially the warning decals. There should be one blade warning
decal on each side of the deck, the “shield missing” decal under the blade belt cover, and the dash decal.
Check (and fill if necessary) engine oil level according to the engine manufacturer’s recommendation.
Check (and fill if necessary) hydraulic fluid level. Use fully SYNTHETIC oil: Mobil-1 15W-50 (see Hydro
Check/Fill section of this manual).
your authorized Wright dealer should perform the Pre-Delivery
Service of the mower.
Check rear tire pressure – 18 – 22 psi. is recommended. Use the higher pressures for heavier operators.
Front Casters are equipped with non-pneumatic tires and do not require any air. Lowering tire pressure will
affect deck pitch. Always check pitch any time tire pressure is set below recommended pressures.
Lubricate all appropriate moving parts (see the Lubrication section of this manual).
Check the battery to see that the cables are tight and connected properly. The battery is 12 volts and is a
maintenance-free battery. Only charge the battery if it will not start the mower properly.
Add regular unleaded gasoline to fuel tank. (use a minimum of 87 octane gasoline) (You may use gasoline
containing up to 10% ethanol and gasoline containing up to 5% of methanol.)
Check brake safety interlock.
Try starting the engine with the parking brake released. (Engine should not start. If engine starts,
service the parking brake locking system)
Apply parking brake
Start the engine according to the engine manufacturer’s recommendation. Let the engine run at low - mid
RPM for several minutes to ensure the engine oil reaches all of the engine parts and gets the hydraulic fluid
circulating through the pumps, etc.
Check if the parking brake locking system prevents the units from being driven while engaged. If not,
service the parking brake locking system.
Release the parking brake. Next, move the hand control levers, one at a time, to make the wheels move in
forward and backward rotation.
Before testing the blade clutch/brake operation, make sure the area is clear and there is nothing vulnerable
Move the engine throttle control to ¾ RPM speed setting.
to possible thrown objects from under the mower. No one should be near the mower deck or in its line of
discharge at this or at any time. The discharge chute deflector should be in the down position.
3
Turn on the blade clutch switch. Run blades for approximately one minute. Next, engage and disengage
the blades a few times about 10 seconds apart. If the blades do not start and stop in a few seconds each
time, service the blade brake system.
With the blades on, disengage the OPC switch to test the Operator Presence Control switch (OPC). A time
delay has been added to the OPC system. The engine should die and the blades should stop with-in 6-9
seconds after stepping off of the foot platform. If not, service the OPC system.
Disengage the blades.
Drive the mower around on a level parking lot. Check that the mower drives in a straight line when both
hand controls are at the full speed position. (If not, refer to How to Perform The Tracking Adjustment section
of this manual) (The control handles may not line up perfectly)
As you drive the mower, listen for any unusual noises and test for irregular operation and adjust or
service as necessary.
Go over the safety information and operating procedures in this manual with the customer. Instruct each
customer in proper operation and observe the customer during their initial operation on a level parking lot.
Repeat until the customer is familiar and comfortable with the basic operation and use of the mower.
• Dealer:

WARNING
1.6 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 steel-toed work boots with thick, textured tread, soft-rubber
soled at all times. Hard or smooth soled shoes are too slippery for a good footing on mower platform.
NEVER wear loose-fitting clothing or jacket pockets that can get caught on the handlebars or control
levers of any mower you drive. Wearing safety glasses, ear protection and safety shoes is advisable and
required by some local ordinances and insurance regulations.
1.7 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 pins, linchpins 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

WARNING
operation. Be sure that all parts of the hand-operated hydraulic control system are tight and secure. This is
to reduce the possibility that the mower could have a loss of control during operation and compromise
operator safety. Ensure deck pitch is between 1/4 - 3/8”. (Refer to the maintenance interval chart at the end
of this manual)
1.8 Regular Mower Safety Maintenance
Keep your Wright mower in good operating condition, and keep safety devices and shields in place and in
working condition. 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. DO NOT change the engine governor settings or over-rev the
engine contrary to engine manufacturer specifications. Failure to comply can compromise operator safety,
shorten equipment life and void your manufacturer’s warranty. 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. Sharpen dull blades. Replace blades when they become excessively worn. 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. When inspecting or changing blades, turn off the blade
clutch switch, apply the parking brake, stop the engine and remove the key. Make sure the chute deflector is
always in place and operating properly. Replace if the deflector becomes worn or ceases to properly deflect
the grass in a safe manner. (Refer to the maintenance interval chart at the end of this manual)
1.9 Work Area Conditions & 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, toys, 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, 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 within 50 feet of 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.
1.10 Initial Operating Safety Guidelines
• Read and understand the warnings on the instrument panel of the mower.
• Keep a firm hold on the stationary handle at all times.
• Keep both feet on the foot platform at all times.
• Know the controls and how to stop quickly.
• Before attempting to start the engine, follow all starting instructions below and in the engine operator’s
manual.
• Look behind before backing up.
7
WARNING
• Before leaving the operator’s position, even momentarily, turn off the blade clutch engagement switch and
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. This could create a rollover hazard.
• 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 or repair service, disengage power to blades, apply the parking brake,
stop the engine, remove ignition key and spark plug wire from spark plug(s).
• All operators of this mower should exercise caution when driving this mower at high speeds. Sudden
acceleration or deceleration may cause serious injury.
• Do not allow inexperienced persons to operate the mower until they have read and understood these
safety instructions. Operate the mower at slower speeds while becoming familiar with it.
• The grass discharge chute deflector must be installed at all times and in the down position except that it
may be raised when cleaning out the deck or a grass catcher is installed or a mulch kit and block-off plate
is properly installed.
• If the mower discharges grass clogs, turn off the blade clutch switch, apply the parking brake, stop the
engine and remove the key before removing obstruction(s).
• Keep all shields and covers in place, namely, all blade and belt covers, engine shields, and grass
discharge chute deflector.
• Keep hands, feet and clothing away from rotating parts, especially the rear wheels, blades, engine
flywheel, belts and pulleys.
• Do not touch engine, muffler or hydraulic system 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 climbing curbs, crossing gravel drives, sidewalks or roads, turn off the blades and wait for them to
stop.
1.11 Safety for Maintenance
• Repairs carried out by untrained or unauthorized personnel may result in personal injury or serious
malfunction of the Stander.
• If Guarding is removed for inspection and component replacement, ensure the parking brake is applied
and key is removed prior to inspecting or making repairs and that the guarding is replaced before
operation.
1.12 Operation In Forward Direction
Always keep a firm grip on the mower stationary handlebar with both hands. Operate the mower slowly until
you become familiar with how the mower operates. Do not operate the mower faster than conditions allow.
For example, hills, wet or bumpy ground, dim light or high grass are all conditions requiring slower speeds.
Never operate the mower at the highest speed unless you are on level, wide, open areas of clearly visible
ground or transporting on paved areas. Speeding with any mower is dangerous, and so is traveling faster
than conditions should permit on this mower. Sudden stops from excessive speed or falling off the mower
may cause serious injury or death.
1.13 Operation In Reverse
Always keep a firm grip on the mower stationary handlebar with both hands. Keep both feet firmly on the
foot platform. Look behind you before backing to prevent injuring yourself or anyone behind you. Operate
8
the mower very slowly, inching it backward until you become familiar with how the mower operates. Always
operate slowly if in an awkward location or position. While backing up never place your foot or feet on the
ground near the back edge of the mower to prevent serious personal injury if the mower were to run over
you.
1.14 Zero-Radius Turn Operation
During zero-radius turns (when one mower wheel rotates backwards while the other rotates forward) drive
extra slowly to reduce the possibility of losing traction, or control, or becoming dizzy. This will help prevent
you from being thrown off the mower. Be aware that if you do a turn on a slope you may go through all of the
orientations to a slope mentioned below and must handle the mower accordingly.
1.15 Operation on Slopes
DO NOT operate on steep slopes 25 degrees or greater for long periods or engine damage may occur. 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. When operating on a slope, travel across the grade whenever
possible, not in an up or down pattern. Reduce speed and exercise extreme caution on slopes and in sharp
turns to prevent tipping or loss of control. Be especially cautious when changing direction on slopes.
When pointing up a slope, your mower has the most weight on the drive wheels and therefore the most
traction at the tires. However, this is the angle that it has the most tendency to tip back (“pop a wheelie.”)
This is the preferred angle for mowing small areas of steeper slopes.
Recommendations for this angle:
• Lean as far forward as possible to add your weight to the front of the mower.
• Accelerate gently. Do not accelerate quickly to avoid “popping a wheelie”.
• If backing down the hill, do not stop suddenly but slow down gradually.
When pointing down a slope, your mower has the least weight on the rear drive wheels and therefore the
least traction at the tires. This is the angle that the mower has the most tendency to slide. However, this is
the angle that it has the least tendency to tip back. Avoid this angle, as it has the least advantage for your
mower.
Recommendations for this angle:
• Lean back with arms stretched out straight while holding onto the stationary handlebar. This transfers
more of your body weight to the rear drive wheels for more traction.
• Do not change speed suddenly to minimize the tendency of going into a slide. Accelerate and decelerate
gently. If you ever go into an uncontrolled slide while pointing down a slope the recommended procedure
is to let go of the handles and jump off if necessary. Otherwise, control the mower gently and stay off
slopes that tend to make the wheels slide.
When crossing a slope sideways, your mower has the average amount of weight on the drive wheels
versus the front wheels, similar to level ground. However, this angle leaves the least weight on the higher
side drive wheel, tending to make it slip. This is the preferred angle for mowing large areas of gentle
slopes.
Recommendations for this angle:
Lean back. This adds weight to the rear drive wheels and will allow you to mow more quickly across the
slope without sliding. These are general guidelines only. The mower function and comfort will vary
depending on mowing environment, operator driving style and preference.
• To reduce the chances of “popping-a-wheelie”, do not accelerate quickly.
9
Note: Excessively worn tire tread is dangerous. Replace tire(s) with less than 3/32” of any tread groove left.
Use tires with the tread pattern recommended by Wright Mfg., Inc. only. Keep the tire pressure in the drive
tires between 18 and 22 psi. Higher pressures will cause the tires to have less traction which may prevent
safe operation. Lower pressure will affect the deck pitch, thus creating a level deck or a reverse pitched deck
and this WILL compromise cut quality. (Refer to tire maintenance and pressure section)
1.16 Fuel Safety
Handle gasoline with care – it is highly flammable. Do not smoke while
handling gasoline. Use an approved gasoline container. Never remove the
fuel cap or add gasoline to a running or hot engine or an engine that has not
been allowed to cool for several minutes after running. Never fill the tank
indoors and always clean up spilled gas. NEVER store the equipment with
gasoline in the tank inside a building where fumes may reach an open flame
or spark. Allow the engine to cool before storing in any enclosure.
1.17 Hydraulic Safety
Keep body and hands away from pin holes or fittings that eject hydraulic fluid under high pressure. Use
paper or cardboard and not hands to search for leaks. Hydraulic fluid escape under high pressure may have
sufficient force to penetrate skin and cause serious injury. If foreign fluid is injected into the skin, it must be
surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.
Seek medical attention immediately. Make sure all hydraulic fluid connections are tight and all hydraulic
hoses and lines are in good condition before starting your Wright mower. Hydraulic fluid is under high
pressure. If you need service on your hydraulic system, please see your authorized Wright dealer.
1.18 Using a Spark Arrester
The engine in this machine is not equipped with a spark arrester muffler. It is in violation of California Public
Resources Code Section 4442 to use or operate the engine on or near any forest-covered, brush-covered, or
grass covered land unless the exhaust system is equipped with a spark arrester meeting any applicable local
or state laws. Other states or federal area may have similar laws.
1.19 Replacement Parts
Use of parts other than specified parts supplied by Wright Manufacturing, Inc. may compromise the safe use
of the mower, are not recommended and their use could void the warranty. Always check with your Dealer
or the Wright Mfg website, www.wrightmfg.com for the Illustrated Parts List for your equipment.
Wright is fully concerned with your safety. Please read the above repeatedly until you fully
