Battery Maintenance - Ferris ISX800 Series Operator's Manual

• Turn the pre-load adjuster so that it moves down
away from the spring, decompressing it, to decrease
the spring's pre-load.
Note: If necessary, a replacement spanner wrench can be
ordered through your authorized Ferris servicing dealer.
6. Re-install the rear drive tires. Torque the lug bolts to
85-95 ft.lbs. (115-129 Nm). Remove the jack stands from
under the unit.
Note: If a collection system is installed on the unit it is
recommended that the rear suspension be adjusted stiffer
due to the added weight of the collection system.
To Adjust the Upper Mounting Position (Rear
Shocks):
1. Park the unit on a flat, level surface. Disengage the PTO,
stop the engine and engage the parking brake.
2. Raise the rear of the unit and secure with jack stands.
The jack stands must be under the bumper. Chock the
front wheels to prevent the unit from rolling.
3. Position the jack under the transmission cradle 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 next higher numbered position (see
Figure 65).

5. Adjust the jack to align the shocks to the shock mounting
holes.
6. Install the upper shock mounting hardware and tighten
securely.
7. Remove the jack from under the transmission cradle.

8. Remove the jack stands from underneath the unit.

Battery Maintenance

DANGER
Be careful when handling the battery.
Battery acid can cause severe burns. Avoid contact with
skin. Wear protective gear (safety goggles/face shield and
gloves) when working with the battery.
Keep the battery out of reach of children.
To avoid an explosion, keep open flames and sparks away
from the battery, especially while charging.
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
This unit is equipped with a maintenance-free BCIU1 battery.
Some units feature a frame style that allows the battery to be
installed perpendicular to the frame rails (Reference Figure
66) and other units feature a frame style that allows the
battery to be installed parallel to the frame rails (Reference
Figure 67).
1. Disconnect the cables from the battery, negative [-] cable
first (A, Figures 66 & 67).
