Pre-Delivery Service of Mower by Dealer
If you are not completely familiar with the Safety Instruction
Manual read it now before proceeding with the Pre-Delivery
WARNING
The Wright Stander is shipped completely assembled and has been adjusted and tested at the factory.
However, due to jostling during 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:
• Remove spark plug wire from spark plug(s).
• 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” under the blade belt covers, 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. The level should be about 1”-1.5” below the top of the
oil fill. Use synthetic oil: Mobil1 15W-50.
• Check rear tire pressure - 18 to 22 psi. is recommended. It should be even on both sides. Use the
higher pressures for heavier operators. Set the tire pressure in the front caster tires between 30
and 40 psi. Higher pressures will help keep the caster tires on their rims when impacted from the
side but give a stiffer ride. Some Front Casters are equipped with non-pneumatic tires and do not
require any air.
• 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.
• Remove the blade belt covers and inspect the belt and idler arm for smooth operation. Also grease the
idler arm(s) if applicable.
• Rotate the blade pulleys slightly to see if they rotate freely and all turn together. There will be
resistance due to the clutch brake.
• Replace the blade belt covers.
• Lubricate all moving parts (see Maintenance Items
• Fill fuel tank with regular unleaded gasoline. Turn fuel valve under fuel tank to the “ON” position.
• DO NOT START THE ENGINE AT THIS TIME. FOLLOW THE NEXT PROCEDURE BEFORE
STARTING. The hydraulic system MUST be checked for proper operation before allowing wheels
to operate on the ground.
• Set the rear of the machine on jack stands or blocks to raise rear wheels off the ground two or three
inches and check to be sure that the mower will not fall off the supports you devise. (Do not
support the mower’s weight on any part of the foot platform.) You must be able to stand on the
mower. The stand(s) must be able to secure the mower from rolling off or away during the next
procedures. Check under the mower deck for any debris or unusual conditions.
• With hand controls in the middle or neutral position, apply the parking brake.
• Open the manual bypass valves on side of each pump a half-a-turn counterclockwise.
• Reattach spark plug wires to spark plugs.
• Before starting the engine be ready to stop it if the wheels begin to turn with the brake on. (If this
happens, check that the manual bypass valves on side of each pump are open at least a half-a-turn
counterclockwise.)
• Start the engine according to the engine manufacturer’s recommendation. Let the engine run at low
RPM for several minutes to get the hydraulic fluid circulating through the pumps. While standing on
the foot platform, release the parking brake. Now gradually close the manual bypass valves on top

of each pump one at a time and see if the wheels start to move. If the wheels move when the hand
controls are in neutral position, adjust the pump neutral adjustment allen screw. The manual
bypass valves on side of each pump should now be firmly closed. (Do not tighten these bypass
valves with a wrench. Only hand tighten). Now try moving the hand control levers, one at a time,
forward and backward. Check to see if the wheels move forward and backward according to
position of the levers. If not, service the hand control system. If the wheels stop when the hand
controls are in the neutral position, the parking brake should now be applied.
• Before testing the blade clutch/brake operation, make sure the area is clear and there is nothing
vulnerable to being thrown from under the mower. No one should be near the mower deck or in its
line of discharge at this time or at any time. The discharge chute deflector should be in the down
position. The parking brake should now be applied. Move the engine throttle to ¾ speed setting.
• Place your feet firmly on the foot platform and turn on the blade clutch switch. Run blades for a minute
or so. Try engaging and disengaging the blades a few times about 10 seconds apart. If the blades
do not start and stop in a short amount of time, service the blade brake system. With the blades
on, now try lifting your feet off the foot platform to test the Operator Presence Control switch (OPC).
The engine should die and the blades should stop in several seconds. If not, service the OPC
system. Try this a couple of times.
• Disengage the blades, set the parking brake, shut off the engine and remove the mower from the
stand(s).
• Drive the mower around on a level parking lot. It is recommended that the slower setting of the
Speed/Sensitivity Adjustment be used. (See further in this manual for information on
Speed/Sensitivity Adjustment.) Be sure that the mower drives in a straight line when both hand
controls are held to the full speed position which is up against the stationary control bar. If not, see
further in this manual for information on tracking adjustment.
• As you drive the mower, listen for any unusual noises and test for irregular operation and adjust or
service as necessary. Next, go over the safety information and operating procedures in this
manual with the customer. Instruct the customer in proper operation and observe the customer
during their initial operation on a level parking lot. Make sure the customer is familiar and
comfortable with the basic operation and use of the mower.

WARNING
User Clothing
DO NOT operate the mower while wearing
sandals, tennis shoes, sneakers, or shorts.
Always wear long non-baggy pants. Wear hightop 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.
WARNING
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
or “hair” pins or cable yoke 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 footoperated Operator Presence Control (OPC)
switch is released. (To test the OPC, follow
instructions in the Operating Instructions
of this manual.) Inspect the two anti-tip rollers
and their respective bolts at the rear of the mower
for tightness and proper 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.
WARNING
section
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. 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. See the instructions in the
Recommended Maintenance
manual for other items of required maintenance.
WARNING
section of this
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
