Rear Suspension Adjustment; Battery Maintenance - Ferris IS600ZB2544 Operator's Manual

Rear Suspension Adjustment

The shock assembly can be adjusted in two ways to allow the
operator to customize the ride according to operator's weight
and/or operating conditions. You have the option of adjusting
the spring pre-load and/or the upper mounting position.
Items to consider before adjusting the suspension.
• Less spring pre-load should be used with light weight
operators, which will provide a softer, more cushioned ride.
• More spring pre-load or upper mounting position #2 should
be used with heavy weight operators, or when a rear-mount
grass bagger system is installed, which will provide a stiffer,
more rigid ride.
To Adjust the Spring Pre-Load:
1. Park machine on a flat, level surface. Disengage the PTO,
stop the engine and engage the parking brake.
2. Raise the rear of the machine and secure with jackstands.
Chock the front wheels to prevent the machine from rolling.
3. Remove the rear drive tires.
WARNING
Use two hands when adjusting the shock springs. This will
prevent the wrench from slipping while pressure is applied.
4. See Figure 55. Using the supplied spanner wrench (p/n
5022853), insert the tip of the wrench into the notch in the
pre-load adjuster. While holding the wrench in place with
one hand, turn counter-clockwise to increase the pre-load,
turn CLOCKWISE to decrease the pre-load. Make sure both
shocks are set to the same amount of pre-load.

5. Reinstall the rear drive tires. Torque the lug bolts to 85-95
ft/lbs. (115-129 Nm). Remove the jackstands from under
the machine.
NOTE: Spanner wrench is located under the seat on the
right-hand side of the machine.
To Adjust the Upper Mounting Position:
1. Park machine on a flat, level surface. Disengage the PTO,
stop the engine and engage the parking brake.
2. Raise the rear of the machine and secure with jackstands.
The jackstands must under the bumper. Chock the front
wheels to prevent the machine from rolling.
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 55). 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

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.
