5.0 Operating Instructions WARNING If you are not completely familiar with the Safety Instruction Manual read it now before proceeding with the operation of the mower. REMEMBER THERE ARE CERTAIN PRECAUTIONS LISTED IN THIS MANUAL THAT YOU MUST NOW TAKE BEFORE STARTING THE MOWER. 5.1 Inspect Mower Before Each Use Inspection of Mower: Do not use the mower if any parts are not maintained in good operating condition. Examine all moving parts prior to each use.
the position of the levers. If not, check to see that the pump release valves are closed. With both feet still firmly placed on the foot platform, increase the engine speed to about half of the way from idle speed. The higher engine speed will make the controls much more responsive and the mower much quicker; Use caution if it is your first time. Now try moving the hand control levers, one at a time, very slightly, forward and backward.
5.5.1 Never Drive Straight Onto or Off a Curb WARNING Never drive straight onto or off a curb. If you do the whole procedure at a very sharp angle it will tend to minimize the contact of the mower deck with the curb and you will be able to more safely control the mower. 5.
5.9 How to Perform the Tracking Adjustments WARNING First ensure that the tire pressure is equal on both rear drive tires. Drive the mower on a level parking lot with engine at full throttle. Check 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, park the mower and stop the engine.
extremely off either because you are installing new parts or other reasons you should only use the faster Speed/ Sensitivity setting to get the tracking to be accurate. After getting the mower to track straight, readjust the neutral adjustment, if necessary. It is normal to need to make these adjustments from time to time as the linkage breaks in or wears. 5.
6.2.1 Deck Adjustments The mower deck can be adjusted for pitch and side-to-side lever. Pitch is the relationship between the front of the deck and the rear of the deck in regards to height of cut. In most cases, a positive pitch (front of the deck lower than the rear of the deck) of ¼” is the optimum setting. These two adjustments can easily be made by using the deck lift rod assemblies attached to the front deck arms and the threaded deck hangers located at the rear of the deck frame.
6.4.1 Replacing the Drive Belt • Stop engine and remove the key and wait for all moving parts to stop. • Remove deck covers. • Remove cutter deck engine to blade belt from clutch. • Raise front of unit and secure • Remove the clutch stop • Remove belt by using a ½” ratchet and extension to relieve belt tension. • Reinstall in reverse order. Figure shows belt configuration. NOTE: Ensure clutch stop is reinstalled. 6.4.
6.5 How to Move the Mower if the Engine Won’t Start Rotate both of the manual “release” valve levers on the rear of each hydraulic pump about ½ turn counterclockwise. It is important not to over tighten these levers. Damage may occur to the pump if this valve is over tightened. WARNING 6.6 Hydraulic System Whenever servicing the hydraulic system, it is of the utmost importance to keep any dirt or debris from getting into the system. Clean off all parts before disassembly and assembly.
6.8 Oil Cooler Removal and Cleaning WARNING Clean oil cooler weekly. Clean more often in dry conditions. To remove oil cooler for a thorough cleaning “STOP ENGINE”, lift thigh pad for access. Loosen knob (1) as far as necessary to slide the cooler back about 3/81/2” until clears locking tabs and then lift up and out. (The cooler knob does not need to be removed) Watch cooler hoses so they do not snap pump fans. The debris screen should be removed before blowing cooler out from the bottom.
6.12 Fuel Evaporation System All Wright Stander ZK’s need to have this mandatory feature. • Do Not alter or remove. • Do Not fill past the “Max Fill Level” line. • Over-filling could result in clogging the roll-over vent and/or contaminating the purge canister. • The vapor canister is located under the dash. • Inspect and clean dust filter every 500 hrs or annually.
6.13 Cutting Blades WARNING In order to maintain the best cut, it is important that the blades are well sharpened and not damaged. Bent or cracked blades or blades with large nicks need to be replaced. Blades must be balanced after sharpening. To change the blades: • Stop engine, remove the key and wait for all moving parts to stop. • Engage the parking brake • Lift front of mower and secure in the raised position with jack stands. • Remove the blade bolt by turning counterclockwise.
6.17 Cleaning the Mower The underside of the mower deck should be checked and cleaned twice daily and more often if the grass being mowed is lush or wet. The entire mower should be cleaned daily at the end of the work day. Cleaning should be done with a leaf blower or low-pressure compressed air. Wash with water only when necessary and do not use a pressure washer or nozzle as the water can enter bearings and electrical connections causing an electrical short, rust and corrosion.
