Snorkel SP22 - Manual (Page 47)

Chapter 8. Operation
The aerial platform may be operated from either the
ground or platform controls.
The aerial platform is not electrically
insulated. Death or serious injury can result
from contact with, or inadequate clearance
from, an energized conductor. Do not go
closer than the minimum safe approach
distance as defined by ANSI.
Pinch points may exist between moving
components. Death or serious injury can
result from becoming trapped between
components, buildings, structures, or other
obstacles. Make sure there is sufficient
clearance around the machine before moving
the chassis, booms, or platform. Allow
sufficient room and time to stop movement to
avoid contact with structures or other
hazards.
The aerial platform can tip over if it becomes
unstable. Death or serious injury can result
from a tip-over accident. Operate the aerial
platform on a firm, flat, level surface. Avoid
travel speeds and/or rough terrain that could
cause sudden changes in platform position.
The platform rated work load is the total weight of
the personnel and equipment that may be lifted in
the platform. The work loads are stated on the
platform rating placard mounted on the toe-board
at the front of the platform.
The aerial platform can tip over if it becomes
unstable. Death or serious injury can result
from a tip-over accident. Do not exceed the
capacity values indicated on the platform
rating placard.
Capacity values indicate the rated lifting capacity
and do not indicate aerial platform stability.
The operator bears ultimate responsibility for
ensuring that the aerial platform is properly set up
for the particular conditions encountered.
■ Preparing for Operation
Use the following procedure to prepare the aerial
platform for operation.
1. Perform a daily inspection as described in
Chapter 6.
2. Place the battery disconnect switch in the on
position.
3. Close and latch the covers.
4. When painting or sandblasting ensure that
the optional hostile environment kit is
properly installed before using the machine
on the job.
■ Ground Controls
The ground controls override the platform controls.
This means that the lower controls can always be
used to operate the platform regardless of the
position of the upper control emergency stop
button.
Boom, turntable, and platform functions may be
operated from the lower controls. The lower
controls may be used for initial set up of the aerial
platform and raising and lowering the platform
while testing or inspection.
Use the following procedure to operate boom or
platform functions using the lower controls (refer to
Figure 7.1).
1. Pull the emergency stop button out.
Figure 7.1—Ground Controls
2. Insert the key into the master switch and turn
the engine on€.
3. Switch to ground operation.
4. Operate the desired boom or platform
lever‚.
5. Hold the lever in the appropriate direction.
6. Release the lever to stop movement.
7. The selected function will remain active until
one of the following occurs.
● The operation lever is released.
● The emergency stop button is pushed in.
