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
Service of the mower. Only your authorized Wright dealer
should perform the Pre-Delivery Service of the mower.
WARNING
The Wright Z is shipped 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. Seat may be detached for
crating purposes. Make sure all hardware is present.
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. The Park Brake and General Safety Decal should in place near the brake lever.
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. The front caster tires are a non-pneumatic style wheel, and
do not require air pressure.
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 sufficiently start the mower.
Remove the blade belt covers and inspect the belt and idler arm for smooth operation.
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. Pressing the lift pedal
all the way down will engage the latch mechanism. Releasing pressure from the pedal should
allow the latch to lock the deck in the transport position. Pressing on the pedal again should
release the latch mechanism and allow the deck height to be set according to the location of the
deck-height detent pin.
Lubricate all moving parts (see Maintenance Items
section of this manual).
Fill fuel tank with regular unleaded gasoline. Turn fuel tank selector valve left or right, depending which
tank is filled with gas. Note: the downward position is off. The fuel tank selector valve is located in
the rear of the seat frame on the left side.
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. 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 neutral and outward position, apply the parking brake.
Open the manual bypass valves on front-side of each pump a half-a-turn counterclockwise. The pump
bypass valves are accessible by lifting the seat tray.
Reattach spark plug wires to spark plugs.
