WARNING

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

The Wright Stander ZK 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 2” – 2 ½” below the top of

the oil fill or using a dipstick, the level will be 4.25” from the bottom of tank. 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. 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.

• 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 cutter deck for proper adjustment. The deck should be approximately ¼” lower in the front than in the rear and the deck should be level side-to-side. If the deck is not adjusted properly, please adjust at this time. See Deck adjustments section of this manual for further instructions.

• Lubricate all moving parts (see Maintenance Items section of this manual).

• Fill fuel tanks with regular unleaded gasoline. Turn fuel valve, located on the right side of upright to the

“ON” position. The down position controls the right tank, the up position controls the left tank. Center position is “OFF” and it is recommended to turn “OFF” when not operating.

• 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.)

mower. Only your authorized Wright dealer should perform the PreDelivery Service of the mower.

• 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 clutch. 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. ZK’s are being set at the factory in 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.

• Dealer: Please fill out and follow the instructions on the Product Registration Form and have the customer fill out his part 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. Then give the customer his copy of the registration form and then keep your copy and mail the remaining copies of the form 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

WARNING

Owner/User Notice:

The owner’s/user’s obligation is to instruct themselves and all potential users in the safe operation of this equipment and be sure they read and follow the instructions in this safety manual and other material provided by Wright Manufacturing, Inc. before using or allowing others to operate the equipment. Do not operate this unit unless you carefully read, understand and follow the assembly, installation, and safety instructions contained in this manual and the warning decals provided on the unit. Do not allow other persons to use this unit unless you make sure they carefully read, understand and follow these instructions. Never allow children to operate or play on the unit.

WARNING

User Experience and Qualifications:

This product is designed for use by physically fit, experienced, professional commercial mower operators who have a minimum of 160 hours of experience operating twelve horsepower and greater industrial mowers. Operators must be 18 years or older and weigh at least 120 pounds and no more than 350 pounds. They must have read and understood this manual. DO NOT allow children to operate the mower. Do not allow adults to operate the mower without proper instruction mentioned above. Never allow passengers on 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 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 to 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

Inspection of 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, linchpin 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 foot-operated Operator Presence Control (OPC) switch is released. (To test the OPC, follow instructions in the Operating Instructions section 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 transmission control system are tight and secure. This is to reduce the possibility that the mower could have a loss of control or safety.

Scheduled Mower Maintenance Safety:

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. Keep the Wright mower in good operating condition, and keep safety devices and shields in place and in working condition. Keep all nuts, bolts, and screws tight to be sure the

WARNING

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. Replace excessively worn blades. Sharpen dull blades. 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. See the instructions in the Recommended Maintenance section of this manual for other items of required maintenance.

Work Area Conditions and 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, 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 near 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.

WARNING

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.
