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 Sentar Sport 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
required 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.

• Check the Rapid-Hite deck height adjustment mechanism for proper operation.

• 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 seated or

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 control 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.
