Drive Speeds; Drive/Lift Level Sensor Interlock; Swing-Out Trays - Snorkel S3215L Operator's Manual

Chapter 9 – Operation
Note
Some early model S3219E and S3220E machines were
not equipped with a drive range switch.
In high the machine will travel up to 2 mph (3.2 km/h)
when the platform is raised less than 8' (2.4 m) and up
to 0.5 mph (0.8 km/h) when the platform is raised above
8' (2.4 m). Place the drive range switch in high for normal
machine operation.
Caution
The extension deck is free to move when the extension
handle locks are disengaged. Personal injury may
result from accidentally extending or retracting the
deck. Make certain both extension handle locks are
fully engaged when the deck is extended in the work-
ing position and when it is stowed. Do not attempt to
extend or retract the platform unless the aerial platform
is on a level surface.
Place the drive range switch in low, with the platform fully
lowered and the extension deck locked in the stowed
position, before driving up a ramp to load the machine
for transport.

Drive Speeds

The drive speed is proportional to the joystick position. The
farther the joystick is moved, the faster the travel speed.
Always slow down before traveling over rough terrain or
any sloped surface.
Drive speed ranges are interlocked through limit switches
that sense the platform position.
When the platform is elevated below approximately
y
6' (1.8 m) the aerial platform may be driven with the
full range of drive speeds.
When the platform is elevated above 6' (1.8 m) only
y
the slowest drive speed will work.
Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury could result from such accidents. Do not alter,
disable, or override any safety device.
Do not use the aerial platform if it drives faster than 0.4
mph (0.6 km/h), which is 7' 7" (5.3 m) in 30 seconds,
when elevated above 6' (1.8 m).

Drive/Lift Level Sensor Interlock

When the platform is elevated above 6' (1.8 m), lift and
drive functions are interlocked through a level sensor
system.
Platform raise and drive functions are disabled and an
alarm sounds when those controls are activated if the
chassis is tilted more than:
44
S3226E
1.5° side-to-side and 4° front-to-rear
S3215L/S3215E/S3219E/S3220E/S4726E/S4732E
2° side-to-side and 4° front-to-rear
If the drive/lift level sensor interlock shuts off the platform
raise and drive functions, lower the platform and drive to
a level surface.

Swing-Out Trays

Batteries and hydraulic components are enclosed in
swing-out trays (refer to Figure 9.4) on each side of the
chassis.
Tray
Figure 9.4 – Swing-Out Trays
The battery trays each contain two batteries. There is
y
a battery tray at the front of the machine, both sides
of the chassis.
The control valve tray on the right side of the chassis
y
contains the hydraulic control valve with the free-
wheeling valve, brake release valve and the brake
hand pump. The diagnostic center LCD display is
also in this tray.
The hydraulic tray on the left side of the chassis con-
y
tains the hydraulic pump, reservoir and fluid filter.
The aerial platform can tip over if it becomes unsta-
ble. Death or serious injury can result from a tip-over
accident. Do not open the trays when the platform is
raised more than eight feet.
To open a tray, pull upward on the latch and swing
y
the tray open.
The latched tray must be opened first, before the bat-
y
tery tray can be opened.
When closing the trays, close the battery tray first. The
y
latched tray holds both trays in the closed position.
