Maintenance

Charging the Battery

Removing the Battery

WARNING

Battery terminals or metal tools could short against metal machine components causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury.

• When removing or installing the battery, Do

Not allow the battery terminals to touch any metal parts of the machine.

• Do Not allow metal tools to short between the battery terminals and metal parts of the machine.

DANGER

Charging or jump starting the battery may produce explosive gases. Battery gases can explode causing serious injury.

• Keep sparks, flames, or cigarettes away from battery.

• Ventilate when charging or using battery in an enclosed space.

• Make sure venting path of battery is always open once battery is filled with acid.

• Always shield eyes and face from battery.

CAUTION

If the ignition is in the “ON” position there is potential for sparks and engagement of components. Sparks could cause an explosion or moving parts could accidentally engage causing personal injury.

Be sure ignition switch is in the “OFF” position before charging the battery.

1.

Park the machine on a level surface and disengage the blade control switch.

2.

Move the motion control levers out to the neutral lock position, engage parking brake, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

3.

Raise the seat.

4.

Disconnect the negative (black) ground cable from the battery post (Figure 53). Retain all fasteners.

DANGER

Battery electrolyte contains sulfuric acid, which is poisonous and can cause severe burns.

Swallowing electrolyte can be fatal or if it touches skin can cause severe burns.

• Wear safety glasses to shield eyes, and rubber gloves to protect skin and clothing when handling electrolyte.

• Do Not swallow electrolyte.

• In the event of an accident, flush with water and call a doctor immediately.

Maintenance

WARNING

Incorrect battery cable routing could damage the machine and cables causing sparks.

Sparks can cause the battery gasses to explode, resulting in personal injury.

• Always disconnect the negative (black) battery cable before disconnecting the positive (red) cable.

• Always connect the positive (red) battery cable before connecting the negative

(black) cable.

Checking the Battery Charge

1.

Remove the battery from the chassis; refer to

Removing the Battery .

2.

Allowing batteries to stand for an extended period 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.

Recommended Jump Starting

Procedure

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.

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

3.

Check the voltage of the battery with a digital voltmeter. Locate the voltage reading of the battery in the table below 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 has an output of

16 volts and 7 amps or less to avoid damaging the battery (see chart below for recommended charger settings).

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

51

Maintenance

CAUTION

Connecting the jumper cables incorrectly

(wrong polarity) can immediately damage the electrical 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 54.

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.

7.

Start the vehicle and remove the cables in the reverse order of connection (the engine block

(black) connection is the first to disconnect).

Installing the Battery

1.

Position the battery in the tray with the terminal posts toward the operating position (Figure 53).

2.

Install the positive (red) battery cable to the positive (+) battery terminal using the fasteners removed previously.

3.

Install the negative battery cable to the negative

(-) battery terminal using the fasteners removed previously.

4.

Slide the red terminal boot onto the positive (red) battery post.

5.

Secure the battery with the strap (Figure 53).
