WARNING
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.

CHECK HYDRAULIC OIL LEVEL
1. Before removing the reservoir cap, make sure the
area around the reservoir cap and fill neck of the
reservoir is free of dust, dirt, or other debris.
2. Unscrew the reservoir cap (B, Figure 19).
3. Look down the filler neck of the hydraulic oil
reservoir (A, Figure 19) and observe the oil level.
When cold, the oil level should be approximately
4” (10 cm) below top of the filler neck.
4. If necessary, add SAE 20W-50 motor oil. DO
NOT use synthetic oils.
5. Reinstall the reservoir cap.
CHANGE HYDRAULIC OIL FILTER
Change Interval:
Every 250 Hours
Filter Part Number:
1719168
NOTE: Removing the oil filter from the filter base
will drain the oil reservoir. Have a suitable container
ready to catch any spilled oil. Ferris recommends this
be a dealer-only service item.
1. Locate the transmission oil filter (E, Figure 20)
at the rear of the battery compartment under the
seat.
2. Lubricate the new filter base with a few drops of
transmission oil. Fill the filter half full of oil.
3. Clean the area around the filter base and remove
the filter. Do NOT drain the hydraulic system oil.
4. Thread the new filter onto the filter base until the
gasket makes contact, then tighten 3/4 of a turn
more.
5. Run the unit for several minutes and check the
transmission oil level.
IMPORTANT NOTE: Use caution after changing
the filter; air in the hydraulic system may affect the
responsiveness of the control levers. Repeat step 5
until the air is out of the system.
BATTERY MAINTENANCE
NOTE: This unit is equipped with a maintenance-free
BCIU1 battery.
Cleaning the Battery and Cables
1. Remove the hydraulic oil reservoir mounting
hardware (C, Figure 20) and then move the
reservoir (D) forward to expose the battery.
2. Disconnect the cables from the battery, negative
(black) cable first (B).
3. Clean the battery terminals and cable ends with a
wire brush until shiny.
4. Reinstall the battery and reattach the battery
cables, positive (red) cable first (A).
5. Coat the cable ends and battery terminals with
petroleum jelly or non-conducting grease.
6. Reposition the oil reservoir and secure in place
with the hardware previously removed.
