The aerial platform is not electrically insulated. Death or serious injury will result from contact
with, or inadequate clearance from, an energized conductor.
Do not go closer than the minimum safe approach distance as dened by the Minimum Safe
Approach Distance section in Chapter 3–Safety.
Regard all conductors as energized.
Allow for electrical wire sag and aerial platform sway.
If the platform, scissors structure, or any part of the aerial platform contacts a high-voltage electrical
conductor, the entire machine can become electrically charged.
If that happens, remain on the machine and do not contact any other structure or object. This includes
the ground, adjacent buildings, poles, and any other objects that are not part of the aerial platform.
Such contact could make your body a conductor to the other object, creating an electrical shock hazard
resulting in death or serious injury.
If an aerial platform is in contact with an energized conductor the platform operator must warn ground
personnel in the vicinity to stay away. Their bodies can conduct electricity creating an electrical shock
hazard resulting in death or serious injury.
Do not approach or leave the aerial platform until the electricity has been turned off.
Do not attempt to operate the lower controls when the platform, scissors structure, or any part of the
aerial platform is in contact with a high-voltage electrical conductor or if there is an immediate danger
of such contact.
Personnel on or near an aerial platform must be continuously aware of electrical hazards, recognizing
that death or serious injury can result from contact with an energized conductor.
California
Proposition 65 Warning
Battery posts, terminals, and related accessories contain
lead and lead components, chemicals known to the
State of California to cause cancer and birth defects or
other reproductive harm. Wash hands after handling.

Chapter 3 – Safety
Knowledge of the information in this manual, and proper
training, provide a basis for safely operating the aerial plat-
form. Know the location of all controls and how they oper-
ate to act quickly and responsibly in an emergency.
Safety devices reduce the likelihood of an accident.
yNever disable, modify, or ignore any safety device.
ySafety alerts in this manual indicate situations where
accidents may occur.
If any malfunction, hazard or potentially unsafe condition
relating to capacity, intended use, or safe operation is sus-
pected, stop aerial platform operation and seek assistance.
The operator bears ultimate responsibility for following
all manufacturer’s instructions and warnings, regulations
and safety rules of their employer and/or any state or
federal law.
Electrocution Hazards
The aerial platform is made of metal components and is
not insulated. Regard all conductors as energized. Do
not operate outside during a thunderstorm.
Minimum Safe Approach Distance
Minimum safe approach distances to energized power
lines and their associated parts must be observed while
operating the aerial platform.
Danger
The aerial platform is not electrically insulated. Death
or serious injury will result from contact with, or in-
adequate clearance from, an energized conductor.
Do not go closer than the minimum safe approach
distance as dened by ANSI.
ANSI publications dene minimum distances that must
be observed when working near bus bars and energized
power lines. Table 1 and Figure 3 are reprinted courtesy

Prestart Inspection
Perform a prestart inspection before each shift as de-
scribed in Chapter 8. Do not use the aerial platform on
the job unless you are trained and authorized to do so.
Work Place Inspection and Practices
Do not use the aerial platform as a ground connection
when welding.
yThe welding ground clamp must be attached to the
same structure that is being welded.
yElectrical current ow can be very intense, causing
serious internal damage to some components.
Inspect the area before and during aerial platform use.
The following are some potential hazards that may be in
the work place:
yDebris
ySlopes
yDrop-offs or holes
yBumps and oor obstructions
yOverhead obstructions
yUnauthorized persons
yHigh voltage conductors
yWind and weather conditions
yInadequate surface and support to withstand load
forces applied by the aerial platform in all operating
congurations
Before using the aerial platform in any hazardous (clas-
sied) location, make certain it is approved and of the
type required by ANSI/NFPA 505 for use in that particular
location.
Know and understand the job site trafc-ow patterns and
obey the agmen, road signs and signals.
While operating the aerial platform, a good safety prac-
tice is to have qualied personnel in the immediate work
area to:
yHelp in case of an emergency
yOperate emergency controls as required
yWatch for loss of control by platform operator
yWarn the operator of any obstructions or hazards that
may not be obvious to them
yWatch for soft terrain, sloping surfaces, drop-offs, etc.
where stability could be jeopardized
yWatch for bystanders and never allow anyone to be
under, or to reach through the scissors structure while
operating the aerial platform
Danger
Pinch points may exist between moving components.
Death or serious injury will result from becoming
trapped between components, buildings, structures,
or other obstacles. Make sure there is sufcient
clearance around the machine before moving the
chassis or platform. Allow sufcient room and time
to stop movement to avoid contact with structures
or other hazards.
Always look in the direction of movement.
yDrive with care and at speeds compatible with the
work place conditions.
yUse caution when driving over rough ground, on
slopes and when turning.
yDo not engage in any form of horseplay or permit rid-
ers any place other than in the platform.
Secure all accessories, containers, tools and other ma-
terials in the platform to prevent them from accidentally
falling or being kicked off the platform. Remove all objects
that do not belong in or on the aerial platform.
Never steady the platform by positioning it against an-
other platform.
Warning
The potential for an accident increases when operat-
ing an aerial platform that is damaged or malfunction-
ing. Death or serious injury could result from such
accidents. Do not operate the aerial platform if it is
damaged or malfunctioning.
Do not operate the aerial platform if it is damaged or not
functioning properly. Qualied maintenance personnel
must correct the problem before putting the aerial platform
back into service.
Operation
Use three points of support when entering or exiting the
platform. For example, use two hands and one foot when
climbing into the platform.
Make sure the area below the platform is free of person-
nel before lowering.
Keep both feet positioned rmly on the platform oor.
yOperate the controls slowly and deliberately to avoid
jerky and erratic operation.
yAlways stop the controls in neutral before going in the
opposite direction.
Do not dismount while the aerial platform is in motion or
jump off the platform.
Properly stow the aerial platform and secure it against
unauthorized operation at the end of each work day,
before transporting, or if it is left unattended.
Tip-Over and Falling Hazards
Operate the aerial platform only on a rm, at, level
surface capable of withstanding all load forces imposed
by the aerial platform in all operating conditions. Refer
to the General Specications chart for the maximum

Chapter 3 – Safety

wheel load and drive/lift level sensor interlock informa-
tion. Raise the platform only when the aerial platform is
on level ground.
Danger
The aerial platform can tip over if it becomes unsta-
ble. Death or serious injury will result from a tip-over
accident. Do not drive or position the aerial platform
for elevated use near any drop-off, hole, slope, soft
or uneven ground, or other tip-over hazard. Do not
raise the platform outdoors in wind speeds above 28
mph (12.5 m/s).
Do not operate the aerial platform within 4′(1.2 m) of any
drop-off or hole.
Do not raise the platform in winds above 28 mph (12.5
m/s). Do not add anything to the aerial platform that will
increase the wind loading such as billboards, banners,
ags, etc.
Never operate the aerial platform without all parts of the
guardrail system in place and the entry doors closed.
Make sure that all protective guards, cowlings, and doors
are securely fastened.
Do not exceed the platform capacity nor the platform-
extension capacity as indicated on the platform rating
placard on the platform. Do not carry loads that extend
beyond the platform guardrails without prior written con-
sent from Snorkel.
Do not operate the aerial platform from trucks, trailers, rail-
way cars, oating vessels, scaffolds, or similar equipment
unless the application is approved in writing by Snorkel.
Do not use the aerial platform as a crane, hoist, jack or
for any purpose other than to position personnel, tools,
and materials.
Do not climb on the guardrails or use ladders, planks,
or other devices to extend or increase the work position
from the platform.
Take care to prevent rope, electrical cords, and hoses,
etc., from becoming caught in or on the aerial platform.
yIf the platform or scissors structure becomes caught
on an adjacent structure or other obstacle and is
prevented from normal motion, reverse the control to
free the platform.
yIf control reversal does not free the platform, evacuate
the platform before attempting to free it.
It is best not to transfer from the platform to another
structure or from the structure to the platform, unless
that is the safest way to do the job. Judge each situation
separately taking the work environment into account. If
it is necessary to transfer from the platform to another
structure the following guidelines apply:
1. If you are using a fall restraint, transfer your anchor-
age from one structure to the other before stepping
across.
2. Remember that you might be transferring to a struc-
ture where personal fall arrest is required.
3. Use the platform entrance, do not climb over or
through the guardrails.
Electrical System
Charge the batteries in a well-ventilated area free of
ame, sparks, or other hazards that might cause re or
explosion.
Warning
Batteries give off hydrogen and oxygen that can com-
bine explosively. Death or serious injury could result
from a chemical explosion. Do not smoke or permit
open ames or sparks when checking the batteries.
Battery acid can damage the skin and eyes. Serious
infection or reaction could result if medical treatment
is not given immediately. Wear face and eye protec-
tion when working near the batteries.
yBatteries contain sulfuric acid that can damage your
eyes or skin on contact.
yWear a face shield, rubber gloves, and protective
clothing when working around batteries.
yIf acid contacts your eyes, ush immediately with clear
water and get medical attention.
yIf acid contacts your skin, wash off immediately with
clear water.
Hydraulic System
The hydraulic system contains hoses with hydraulic uid
under pressure.
Danger
Hydraulic uid escaping under pressure can have
enough force to inject uid into the esh. Serious
infection or reaction will result if medical treatment is
not given immediately. In case of injury by escaping
hydraulic uid, seek medical attention at once.
Do not place your hand or any part of your body in front
of escaping hydraulic uid. Use a piece of cardboard or
wood to search for hydraulic leaks.
Placards and Decals
The aerial platform is equipped with placards and decals
that provide instruction for operation and accident preven-
tion. Do not operate the aerial platform if any placards or
decals are missing, damaged, or illegible.

Chapter 4 – Safety Devices
This aerial work platform is manufactured with safety
devices, placards, and decals to reduce the likelihood
of an accident.
yFor the safety of all personnel, do not disable, modify,
or ignore any safety device.
ySafety devices are included in the daily prestart
inspection.
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.
If any safety devices are defective, remove the aerial
platform from service until qualied maintenance person-
nel can make repairs.
Emergency Stop Controls
There is an emergency stop control at the lower and
upper controls.
At the lower controls, the emergency stop is a two-posi-
tion red push button (refer to Figure 4.1).
Figure 4.1 – Lower Controls
yPush the emergency stop button inward to disconnect
power to all control circuits.
yPull the button outward to restore power.
Note
The lower controls override the upper controls. If the up-
per control emergency stop button is engaged, the lower
controls can still be used to operate the aerial platform.
At the upper controls, the emergency stop is a two-posi-
tion red push button (refer to Figure 4.2).
Push the emergency stop button inward when the
upper controls are not in use to protect against un-
intentional operation.
Figure 4.2 – Upper Control Panel Front
yPush the emergency stop button inward to disconnect
power to the upper control circuits.
yPull the button outward to restore power.
Control Select/Ground Operation Switch
The control select/ground operation switch (refer to Figure
4.1) prevents platform movement if the platform raise/low-
er switch on the lower control panel is accidentally moved.
Hold the switch downward continually in the lower control
position to enable the platform raise/lower switch func-
tions.
Upper Control Interlock Switch
The interlock switch (refer to Figure 4.3) prevents platform
movement if the joystick on the upper control panel is
accidentally moved.
Engage the interlock by grasping the joystick and pulling
the switch toward the handle to activate the steering,
drive, lift and lower functions.

The drive and lift functions will not operate and an alarm
will sound if the chassis is tilted more than:
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
Lower the platform and drive to a level surface when the
drive/lift level sensor alarm sounds.
The drive/lift level sensor system is for added protection
and does not justify operating on anything other than rm,
at, level surfaces.
Lowering Alarm
When the joystick is moved out of neutral to lower the
platform, the alarm emits a loud beeping sound to warn
personnel in the work area to stand clear.
Danger
Pinch points exist on the scissors structure. Death
or serious injury will result if the scissors structure
lowers onto personnel within the scissors arms or
under the raised platform. Stand clear while raising
and lowering the platform.
Be careful when lowering the platform. Keep hands and
ngers away from the scissors structures components.
Emergency Lowering Lever/Handle
The emergency lowering lever/handle may be used to
lower the platform if there is a malfunction in the hydraulic
or electrical system.
The lever for the S3215L/S3215E/S3219E is mounted at
the front of the aerial platform (refer to Figure 4.5).
Figure 4.5 – Front of Machine
Drive Motion Alarm
When the joystick is moved out of neutral to drive the
aerial platform, the alarm emits a loud beeping sound to
warn personnel in the work area to stand clear.
Pothole Protector Skids
The pothole protector skids automatically lower when the
platform is elevated approximately 24″(61 cm). Ground
clearance is reduced from 2.63″(6 cm) to 3/4″ (1.9 cm)
when the skids lock into position (refer to Figure 4.4).
Figure 4.4 – Pothole Protector Skids
Danger
The aerial platform can tip over if it becomes unsta-
ble. Death or serious injury will result from a tip-over
accident. Do not drive or position the aerial platform
for elevated use within 4′(1.2 m) of any drop-off, hole,
or other tip-over hazard.
This protection system limits the tilt angle if a wheel is
driven into a drop-off or hole. This greatly reduces the
likelihood of the aerial platform tipping over.
The pothole protection system is for added protection and
does not justify operating near drop-offs or holes.
Drive/Lift Pothole Protector Interlock
The aerial platform drive and lift functions are interlocked
through a limit switch that senses whether or not the
pothole protection linkage is locked into position. The
drive/lift pothole interlock operates when the platform is
elevated approximately 6′(1.8 m).
If an obstruction under the skids, or some other impair-
ment prevents the skids from locking into position, the
drive and steer functions will not operate.
Lower the platform and remove the obstruction when the
drive/lift pothole protector interlock is engaged.
Drive/Lift Level Sensor Interlock
The aerial platform drive and lift functions are interlocked
through a level sensor system. The drive/lift level sensor
interlock operates when the platform is elevated approx-
imately 6′(1.8 m).
