1 3
Before using the work platform make sure the platform is level. If the platform is more than three (31
degrees out of level, it must be adjusted. The work platform must be on firm level surface with nothing in
the basket when this adjustment is made.
1.
Adjustment is performed at the lower control box.
2. Turn the two (2) valves on the turntable counter clockwise and open fully.
3.
If the platform is tilted forward, operate the "Boom Retraction Switch" until the platform is level,
then fullyclose both valves by turning clockwise.
4. If the platform is tilted backwards, operate the "Boom Extension Switch" until the platform is level,
then fully close both valves by turning clockwise.
5.
Raise the platform from the base controls several times to make sure the platform remains level.
6. If the platform doesn't remain level after the adjustment is made there may be air in the system. To
bleed the air, open the two (2) valves on the turntable by turning counter clockwise. Operate the
"Boom Extension Switch" to fully extend and fully retract the boom three or four times. Again level
the platform per instructions in step 1 thru 5. Raise the boom several times to make sure the
platform remains level.
