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. Simplicity recommends this be a dealer-only
service item.
1. Locate the transmission oil filter (A, Figure 20).
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.
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) 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.

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.
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.
