• 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.
