2. Check with engine cold.

3. Clean area around dipstick. Remove dipstick and wipe oil off. Reinsert the dipstick according to the engine manufacturer's recommendations. Remove the dipstick and read the oil level.

4. If the oil level is low, wipe off the area around the oil fill cap, remove cap and fill to the “FULL” mark on the dipstick. Exmark 4-Cycle Premium Engine Oil is recommended; refer to the Engine Owner's manual for an appropriate API rating and viscosity. Do Not overfill.

Important: Do Not operate the engine with the oil level below the “LOW” (or “ADD”) mark on the dipstick, or over the “FULL” mark.

Allowing batteries to stand for an extended period of time without recharging them will result in reduced performance and service life. To preserve optimum battery performance and life, recharge batteries in storage when the open circuit voltage drops to 12.4 volts.

Note: To prevent damage due to freezing, battery should be fully charged before putting away for winter storage.

Charge batteries in an open well ventilated area, away from spark and flames. Unplug charger before connecting or disconnecting from battery. Wear protective clothing and use insulated tools.

For Kohler, Briggs Non-EFI, and Kawasaki machines: Check the voltage of the battery with a digital voltmeter or with the message display. If the ignition key is turned to the “on” position for a few seconds, the battery voltage will be displayed in the area where the hours are normally displayed. Locate the voltage reading of the battery in the table and charge the battery for the recommended time interval to bring the charge up to a full charge of 12.6 volts or greater.

Important: Make sure the negative battery cable is disconnected and the battery charger used for charging the battery should have an output of 16 volts and 7 amps or less to avoid damaging the battery (see chart for recommended charger settings). This is especially important on Kohler EFI (Electronic Fuel Injection) units. Failure to do so may damage the ECU (Electronic Control Unit).

For Briggs EFI machines: Check the voltage of the battery with a digital voltmeter or with the message display. When the ignition is set to accessory mode, the module will display the battery voltage. If the voltage is less than 12.4 volts, the battery may need to be charged.

Important: In order to prevent damage to the battery, use an automatic 12 volt smart charger approved for use with AGM type batteries with an output of 3.5 amps or less. Exmark recommends the use of battery charger P/N 135-7024. Make sure the negative battery cable is disconnected before charging and that the charger is set to the correct mode for 12 volt AGM batteries.

Important: For EFI machines: Unplug the harness from the ECU before performing any welding on the equipment.

1. Check the weak battery for terminal corrosion (white, green, or blue “snow”), it must be cleaned off prior to jump starting. Clean and tighten connections as necessary.

   Caution

   Corrosion or loose connections can cause unwanted electrical voltage spikes at anytime during the jump starting procedure.

   Do Not attempt to jump start with loose or corroded battery terminals or damage to the engine or EFI may occur.

   Danger

   Jump starting a weak battery that is cracked, frozen, has low electrolyte level, or an open/shorted battery cell, can cause an explosion resulting in serious personal injury.

   Do Not jump start a weak battery if these conditions exist.

2. Make sure the booster is a good and fully charged lead acid battery at 12.6 volts or greater. Use properly sized jumper cables (4 to 6 AWG) with short lengths to reduce voltage drop between systems. Make sure the cables are color coded or labeled for the correct polarity.

   Caution

   Connecting the jumper cables incorrectly (wrong polarity) can immediately damage the electrical and/or EFI system.

   Be certain of battery terminal polarity and jumper cable polarity when hooking up batteries.

   Note: The following instructions are adapted from the SAE J1494 Rev. Dec. 2001 – Battery Booster Cables – Surface Vehicle Recommended Practice (SAE – Society of Automotive Engineers).

   Warning

   Batteries contain acid and produce explosive gases.

   • Shield the eyes and face from the batteries at all times.

   • Do Not lean over the batteries.

   Note: Be sure the vent caps are tight and level. Place a damp cloth, if available, over any vent caps on both batteries. Be sure the vehicles do not touch and that both electrical systems are off and at the same rated system voltage. These instructions are for negative ground systems only.

3. Connect the positive (+) cable to the positive (+) terminal of the discharged battery that is wired to the starter or solenoid as shown in Figure 40.

   

   Figure 40

   1. Positive (+) cable on discharged battery
   2. Positive (+) cable on booster battery
   3. Negative (–) cable on the booster battery

   5. Booster battery
   6. Discharged battery
   7. Engine block

4. Connect the other end of the positive cable to the positive terminal of the booster battery.

5. Connect the black negative (–) cable to the other terminal (negative) of the booster battery.

6. MAKE THE FINAL CONNECTION ON THE ENGINE BLOCK OF THE STALLED VEHICLE (NOT TO THE NEGATIVE POST) AWAY FROM THE BATTERY. STAND BACK (see Figure 41).

   

   Figure 41

   1. Engine block
   2. Negative (–) cable

7. Start the vehicle and remove the cables in the reverse order of connection (the engine block (black) connection is the first to disconnect).

Note: A malfunctioning machine battery may cause the charging voltage to exceed 18.5 volts. The engine will turn off if there is a charge above 18.5 volts. Turn the ignition switch off, then on again to reset the engine before restarting the machine.

1. Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.

2. Lift deck and secure in raised position as stated in the Clean Grass Build-Up Under Deck section.

3. Inspect blades and sharpen or replace as required.

4. Reinstall the blades (if they were removed) in the following order:

   1. Install bushing through blade with bushing flange on bottom (grass) side of blade.

      

      Figure 42

      1. Install bushing in blade prior to installing bushing in spindle.

   2. Install bushing/blade assembly into spindle. Make sure the splines on the bushing are engaged in the spindle before tightening the bolt.

      

      Figure 43

      1. Use wrench here for blade installation. This nut has been torqued to 90 ft-lb (122 N-m) minimum
      2. Torque to 50-60 ft-lb (68-81 N-m) Apply lubricant to threads as needed to prevent seizing. Copper-based anti-seize preferable. Grease acceptable substitute.

   3. Apply lubricant to threads of blade bolt to prevent seizing. Copper-based anti-seize preferable. Grease acceptable substitute. Install blade bolt finger tight. Place wrench on the top spindle nut then torque the blade bolts to 50-60 ft-lb (68-81 N-m).

   Important: On rear discharge decks, the RH blade rotates counterclockwise. Be sure to reinstall that blade onto the RH spindle only.

   Warning

   Incorrect installation of the blade or components used to retain the blade can be dangerous. Failure to use all original components and assembled as shown could allow a blade or blade component to be thrown out from under the deck resulting in serious personal injury or death.

   Always install the original Exmark blades, blade bushings, and blade bolts as shown.

Important: It is essential that operator safety mechanisms be connected and in proper operating condition prior to use.

Note: If machine does not pass any of these tests, Do Not operate. Contact an Authorized Service Dealer.

Note: To prevent engine cut-outs on rough terrain, the seat has a 1/2 second time delay before the engine begins to shutdown.

7. Brake pole

Removing the Shim:

1. Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake. Allow the machine to cool completely before starting these instructions.

2. Using a pneumatic line, blow out any debris from under the brake pole and around the brake spacers.

3. Check the condition of the wire harness leads, connectors, and terminals. Clean or repair as necessary.

4. Verify that 12V is present at the clutch connector when the PTO switch is engaged.

5. Measure the gap between the rotor and armature. If the gap is greater than .04 inch (1 mm), proceed with the following steps:

   1. Loosen both brake mounting bolts one-half to one full turn (see Figure 67).

      Note: Do Not remove the brake pole from the field shell/armature. The brake pole has worn to match the armature and needs to continue to match after the shim is removed to ensure proper brake torque.

      

      Figure 67

      1. Brake mounting bolt
      2. Shim

   2. Using needle nose pliers, or by hand, take hold of the tab and remove the shim (Do Not discard the shim until proper clutch function has been confirmed).

   3. Using a pneumatic line, blow out any debris from under the brake pole and around the brake spacers.

   4. Re-torque each bolt (M6 x 1) to 10 ft-lb (13 N-m) +/-0.5 ft-lb (0.7 N-m).

   5. Using a 0.010 inch thick feeler gauge, verify that a gap is present between the rotor and armature face on both sides of the brake pole as shown. (Due to the way the rotor and armature faces wear (peaks and valleys) it is sometimes difficult to measure the true gap.)

      

      Figure 68

      1. Feeler gauge
      

      Figure 69

      1. Feeler gauge

      • If the gap is less than 0.010 inch, then reinstall the shim and reference the Troubleshooting section.

      • If the gap is sufficient, proceed to the safety check in step 6.

   6. Perform the following safety check:

      1. Sit on the seat and start the engine.

      2. Make sure the blades Do Not engage with the PTO switch “off” and the clutch disengaged.

         If the clutch does not disengage, reinstall the shim and reference the Troubleshooting section.

      3. Engage and disengage the PTO switch ten consecutive times to ensure the clutch is functioning properly. If the clutch does not engage properly, reference the Troubleshooting section.

Located on either side of the fuel tank, below the seat are the pump control linkages. Rotating the pump linkage with a 1/2 inch wrench allows fine tuning adjustments so that the machine does not move in neutral. Any adjustments should be made for neutral positioning only.

1. Prior to starting the engine, push the deck lift pedal and remove the height of cut pin. Lower deck to the ground.

2. Raise the rear of machine up and support with jack stands (or equivalent support) just high enough to allow drive wheels to turn freely.

3. Remove the electrical connection from the seat safety switch, located under the bottom cushion of the seat. The switch is a part of the seat assembly.

4. Temporarily install a jumper wire across the terminals in the connector of the main wiring harness.

5. Start engine. Brake must be engaged and motion control levers out to start engine. Operator does not have to be in the seat because of the jumper wire being used. Run engine at full throttle and release brake.

6. Run the unit at least 5 minutes with the drive levers at full forward speed to bring hydraulic oil up to operating temperature.

   Note: The motion control lever needs to be in neutral while making any necessary adjustments.

7. Bring the motion control levers into the neutral position. Adjust pump control rod lengths by rotating the double nuts on the rod in the appropriate direction until the wheels slightly creep in reverse (Figure 70). Move the motion control levers to the reverse position and while applying slight pressure to the lever allow the reverse indicator springs to bring the levers back to neutral. The wheels must stop turning or slightly creep in reverse.
