Maintenance Procedure

• Replace the secondary air cleaner element (May need more often under severe conditions.

See the Engine Owner’s Manual for additional information.)

• Change the hydraulic filter and fluid.

• Check the wheel hub slotted nut torque specifications.

• Check the wheel lug nuts.

• Check the park brake adjustment.

• Grease the deck and pump idler pivots.

• Grease the front caster pivots.

Periodic Maintenance

Check Engine Oil Level

Service Interval: Before each use or daily

1. Stop engine and wait for all moving parts to stop.

Make sure unit is on a level surface.

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. Use oil as specified in

Engine Owner’s Manual. 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.

Check Battery Charge

Service Interval: As required

WARNING

CALIFORNIA

Proposition 65 Warning

Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of

California to cause cancer and reproductive harm. Wash hands after handling.

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.

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).

Recommended Jump

Starting Procedure

Service Interval: As required

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 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 19.
