Confirm the Proper
Brake Configuration
Note: Genie requires that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
Proper brake configuration is essential to safe
operation and good machine performance.
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.
CHECKLIST B PROCEDURES
B-7
Check the Oil Level in the
Drive Hubs
Note: Genie requires that this procedure be
performed every 250 hours or quarterly, whichever
comes first.
Failure to maintain proper drive hub oil levels may
cause the machine to perform poorly and
continued use may cause component damage.
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 plugs, then
install the plugs into the hub.
5 Check the torque of the drive hub mounting
bolts. Refer to Section 2, Specifications.
6 Repeat this procedure for each drive hub.
