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 Service of the mower. Only your authorized Wright dealer should perform the Pre-Delivery Service of the mower.

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.

1

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. It will be necessary to use a pair of locking pliers to activate the seat OPC plunger switch while standing beside the unit. Release the Parking Brake cautiously as the wheels may start to move. Now gradually tighten the manual bypass valves on the front 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. This procedure is described in the Operating instructions portion of this manual. 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. Remove locking pliers from OPC, the blade testing will require that you are seated on the unit for your safety. Failure to comply could result in serious injury.

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. Move the engine throttle to ¾ speed setting. Note: the Blades will not operate in with the parking brake engaged.

Be sure that you are sitting on the operator seat 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 weight off the operator seat to test the Operator Presence Control switch (OPC). The engine should die and the blades should begin to stop after a ½ second delay. The blades should come to a 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. Be sure that the mower drives in a straight line when both hand controls are held to the full speed position. 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.

Dealer: Please fill out and follow the instructions on the Product Registration Form and have the customer fill out their portion of the form. After the Product Registration Form is filled out and signed by the customer and a representative from your dealership, please send or fax it within 14 days to your Wright Manufacturing Distributor according to the directions on the Form. Give the customer their copy of the registration form and keep your copy for your records. The remaining copies of the forms should be mailed to your Wright Manufacturing Distributor. The limited warranty is not valid unless the mower is registered and all of the above steps are taken. Remember, the purchaser is both your and our customer and his satisfaction is very important. Thank you for supporting our products.

The mower is now ready for delivery to your customer
