CHECK /FILL TRANSMISSION OIL

Oil Type: 20W-50 conventional detergent motor oil.

1.Check the oil level when the unit is cold. The inspection port is located on the inside of the right tank cover. The oil level should be within 1/2” (1.3 cm) of the horizontal level mark (D, Figure 22). If the oil is below this level, proceed to step 2.

2.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.

Loosen the locking capscrew (E, Figure 21) securing the locking tab (D), slide the lock tab back, and remove the cap (B).

3.Add oil up to the full mark (D, Figure 22).

4.Reinstall the reservoir cap, move the locking tab between two notches, and tighten the locking capscrew.

TRANSMISSION OIL FILTER CHANGE

Change Interval: Every 250 Hours

Filter Part Number: 1719168

1.Locate the transmission oil filter (C, Figure 22) 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.

NOTE: The oil will drain from the reservoir tank if the new filter is not quickly reinstalled.

5.Run the unit for several minutes and check the transmission oil level (see previous page).

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.
