PROCEDURES

Test the Platform Rotation
(if equipped)
Testing the platform rotation for malfunctions is
essential for safe machine operation. The platform
rotator is operated by manually turning the hand
crank in either a clockwise or counterclockwise
direction.
1 Turn the hand crank at the platform in the
clockwise direction.
Result: The platform should rotate to the right
and operate smoothly without any hesitation or
binding.
2 Turn the hand crank at the platform in the
counterclockwise direction.
Result: The platform should rotate to the left
and operate smoothly without any hesitation or
binding.
B-12
Inspect the Hydraulic Tank Cap
Venting System
Genie requires that this procedure
be performed quarterly or every
250 hours, whichever comes first.
Perform this procedure more often
if dusty conditions exist.
A free-breathing hydraulic tank cap is essential for
good machine performance and service life. A dirty
or clogged cap may cause the machine to perform
poorly. Extremely dirty conditions may require that
the cap be inspected more often.
1 Remove the breather cap from the hydraulic
tank.
2 Check for proper venting.
Result: Air passes through the breather cap.
Result: If air does not pass through the cap,
clean or replace the cap. Proceed to step 3.
When checking for positive tank
cap venting, air should pass freely
through the cap.
3 Using a mild solvent, carefully wash the cap
venting system. Dry using low pressure
compressed air. Repeat step 2.
4 Install the breather cap onto the hydraulic tank.
