Battery Maintenance; Battery Service - Ferris 5900832 Operator's Manual

3. Position the jack under the cross member that ties the
suspension arms together and slowly raise the rear
suspension to relieve the pressure on the upper shock
mounting bolts.
NOTE: This will require small adjustments to the jack's position.
The shock should move freely on the mounting bolt when the
pressure is relieved.
4. Remove the upper shock mounting hardware and pivot the
shock to the position #2 (see Figure 52). Adjust the jack to
align the shock mounts to the shocks.
5. Reinstall the upper shock mounting hardware and tighten
securely.
6. Remove the jack from under the suspension cross member.
7. Remove the jackstands from under the machine.

Battery Maintenance

Models with Center Mounted Hydraulic Tank
This unit is equipped with a maintenance-free BCIU1 battery.
WARNING
Keep open flames and sparks away from the battery.
• Be careful when handling the battery.
• Avoid spilling electrolyte.
• Keep flames and sparks away from the battery.
• When removing or installing battery cables, disconnect
the negative cable FIRST and reconnect it LAST. If not
done in this order, the positive terminal can be shorted to
the frame by a tool.
Cleaning the Battery and Cables
1. Remove the hydraulic oil reservoir mounting hardware (A,
Figure 53) and move the reservoir (B) forward to expose the
battery.

2. Disconnect the cables from the battery, negative [-] cable
first (C).
3. Clean the battery terminals and cable ends with a wire brush
until shiny.
4. Reinstall the battery and reattach the battery cables, positive
[+] cable first (D).
5. Coat the cable ends and the battery terminals with petroleum
jelly or non-conducting grease.
6. Reposition the oil reservoir and secure in place with the
hardware previously removed.

Battery Service

WARNING
Keep open flames and sparks away from the battery; the
gasses coming from it are highly explosive. Ventilate the battery
well during charging.
Checking Battery Voltage
A voltmeter can be used to determine condition of battery. When
engine is off, the voltmeter shows battery voltage, which should
be 12 volts. When engine is running, the voltmeter shows voltage
of charging circuit which normally is 13 to 14 volts.
A dead battery or one too weak to start the engine may not mean
the battery needs to be replaced. For example, it may mean that
the alternator is not charging the battery properly. If there is any
doubt about the cause of the problem, see your dealer. If you
need to replace the battery, follow the steps under Cleaning the
Battery & Cables in the Regular Maintenance Section.
Charging a Completely Discharged Battery
1. Be aware of all the safety precautions you should observe
during the charging operation. If you are unfamiliar with the
use of a battery charger and hydrometer, have the battery
serviced by your dealer.
2. Add distilled water sufficient to cover the plate (fill to the
proper level near the end of the charge). If the battery is
extremely cold, allow it to warm before adding water because
the water level will rise as it warms. Also, an extremely cold
battery will not accept a normal charge until it becomes
warm.
3. Always unplug or turn the charger off before attaching or
removing the clamp connections.
4. Carefully attach the clamps to the battery in proper polarity
(usually red to [+] positive and black to [-] negative).
5. While charging, periodically measure the temperature of the
electrolyte. If the temperature exceeds 125° F (51.6° C), or
if violent gassing or spewing of electrolyte occurs, the
charging rate must be reduced or temporarily halted to
prevent battery damage.
6. Charge the battery until fully charged (until the specific gravity
of the electrolyte is 1.250 or higher and the electrolyte
temperature is at least 60° F). The best method of making
certain a battery is fully charged, but not over charged, is to
measure the specific gravity of a cell once per hour. The
battery is fully charged when the cells are gassing freely at
low charging rate and less than 0.003 change in specific
gravity occurs over a three hour period.
