Confirm the Proper
Brake Configuration
Proper brake configuration is essential to safe
operation and good machine performance.
Hydrostatic brakes and hydraulically-released,
spring-applied individual wheel brakes can appear
to operate normally when they are actually not
fully operational.
1 Check each torque hub disconnect cap to be
sure it is in the engaged position.
2 Be sure the free-wheel valve on the drive pump
is closed (clockwise).

Check the Oil Level
in the Torque Hubs
Failure to maintain proper torque hub oil levels
may cause the machine to perform poorly and
continued use may cause component damage.
Drive Torque Hubs
1 Drive the machine to rotate the hub until the
plugs are located one on top and the other at
90 degrees.
2 Remove the plug located at 90 degrees and
check the oil level.
Result: The oil level should be even with the
bottom of the plug hole.
3 If necessary, remove the top plug and add oil
until the oil level is even with the bottom of the
side plug hole.
4 Apply pipe thread sealant to the plug, and then
install it in the torque hub.
5 Repeat this procedure for each drive torque
hub.
