Test the Drive Speed -
Raised Position
Genie requires that this procedure be performed
every 250 hours or quarterly, whichever comes
first.
Proper drive function movement is essential to
safe machine operation. The drive function should
respond quickly and smoothly to operator control.
Drive performance should also be free of
hesitation, jerking and unusual noise over the
entire proportionally controlled speed range.
1 Create start and finish lines by marking two
lines on the ground 40 feet / 12.2 m apart.
2 Start the engine from the platform controls.
3 Raise the platform to approximately
8 feet / 2.4 m.
4 Choose a point on the machine; i.e., contact
patch of a tire, as a visual reference for use
when crossing the start and finish lines.
5 Bring the machine to maximum drive speed
before reaching the start line. Begin timing
when your reference point on the machine
crosses the start line.
6 Continue at maximum speed and note the time
when your reference point on the machine
crosses the finish line. Refer to Section 2,

Inspect the Fuel Tank Check
Valve Venting System -
Gas/LPG Models
Note: For machines located in the United States,
EPA Certificate 40 CFR Part 1060 requires that the
check valve be in proper working condition.
Genie requires that this procedure be performed
every 250 hours or quarterly, whichever comes
first. Perform this procedure more often if dusty
conditions exist.
Free-breathing fuel tank check valve is essential for
good machine performance and service life. A dirty
or clogged check valve may cause the fuel tank to
not vent properly. Extremely dirty conditions may
require that the check valve be inspected more
often.
Explosion and fire hazard. Engine
fuels are combustible. Perform this
procedure in an open, well-
ventilated area away from heaters,
sparks, flames and lighted
tobacco. Always have an approved
fire extinguisher within easy reach.
1 Locate the check valve near the top of the fuel
tank.
2 Remove the check valve from the fuel lines.
