Snorkel S2545 - Manual (Page 30)

■ Level Sensor Interlock
Perform this test after verifying proper operation
of the pothole protector interlock.
1. Position the aerial platform on a smooth, flat,
level surface.
2. Remove all persons and materials from the
platform.
3. From the lower controls, raise the platform to
access the level sensor at the rear of the
chassis (refer to Figure 8.14).
Figure 8.14—Level Sensor
4. Pull the level sensor to the side as far as
possible while raising the platform. The
platform should stop raising and the alarm
should sound at less than 7
′ (2 m) of platform
elevation.
The potential for an accident increases when
safety devices do not function properly. Death
or serious injury can result from such
accidents. Do not alter, disable, or override
any safety device.
5. If platform does not stop raising or the alarm
does not sound, remove the machine from
service until the problem is corrected.
■ Emergency Lowering
Using the lower controls fully raise the platform.
Locate the emergency lowering handle (refer to
Figure 8.15) at the front of the aerial platform.
Figure 8.15—Emergency Lowering Handle
While standing clear of the scissors structure, pull
the handle outward. The platform will begin to
lower as the handle is pulled. Release the handle
to stop.
■ Safety Prop
Using the lower controls, raise the platform until
the open height between the arm center pins is
approximately 24
″ (refer to Figure 8.16).
Figure 8.16—Safety Prop
Swing the safety prop upward from the storage
position to the support position. Inspect the safety
prop for damage and deformation. Check for
cracks in the welds that hold the handle and the
support channel onto the tube.
