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.

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.

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.
