Special Limitations
6 A46JRT – 0260999
Special Limitations
Travel with the platform raised is limited to creep speed
range. Elevating the platform is limited to firm, level
surfaces only.
Danger
The elevating function shall ONLY be used when the
work platform is level and on a firm surface.
Platform Capacity
Two people and tools may occupy the platform. The max-
imum platform capacity for the aerial platform is stated in
the “Specifications” on page 24.
Danger
DO NOT exceed the maximum platform capacity or
the platform occupancy limits for this machine.
Manual Force
Manual force is the force applied by the occupants to
objects such as walls or other structures outside the
work platform.
The maximum allowable manual force is limited to 200 N
(45 lb) of force per occupant, with a maximum of 400 N
(90 lb) for two occupants.
Danger
DO NOT exceed the maximum amount of manual
force for this machine.
Platform Overload Sensing System
All functions are stopped from the upper and lower con-
trols, when the platform overload limit is exceeded. The
horn will sound intermittently and the platform overload
light will blink until the excess load is removed from the
platform. At that time, the machine functions are again
operational.
Caution
The emergency power system is for emergency
lowering and stowing only. The length of time the
pump can be operated depends on the capacity of the
battery. Do not use this system for normal operation.
If the platform overload sensing system is tripped while
operating the machine, the emergency power system may
still be used for emergency machine operation.
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. Do not exceed the capacity values indicated
on the platform rating placard.
The overload sensing system is not active when the
machine is being driven with the booms in the stowed
position. This allows the machine to be driven without
the system sensing an overload due to rough ground
conditions.

Operation
A46JRT – 0260999 15
Operation
The aerial platform may be operated from either the lower
or upper controls.
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 defined by national safety regulations.
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 sufficient clear-
ance 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 will result from a tip-over ac-
cident. 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. 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.
The platform rated work load is the total weight of the per-
sonnel and equipment that may be lifted in the platform.
The work loads are stated on the platform rating placard
at the:
• rear of the platform
• lower controls
• upper controls
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. 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.
Cold Weather Start-Up
If the ambient temperature is 0°C (32°F) or below, the
engine and hydraulic system oil may need to be warmed
before operation. Do not operate the engine at more than
a fast idle until the engine and hydraulic oil has had a
chance to warm.
Cold, thick hydraulic oil does not flow well and may cause
delay in response to control movement. Cold hydraulic oil
may also cause cavitation and pump damage.
Hydraulic System Cold Weather Warm-Up
Some machines may have a hydraulic fluid warm-up
system that will automatically warm the fluid upon acti-
vating the warm-up switch. The hydraulic fluid may also
be warmed manually if the machine is not equipped with
the optional warm-up system.
Caution
Not all hydraulic fluid is suitable to use in the hydrau-
lic system. Some have poor lubricating character-
istics and may increase component wear. Only use
hydraulic fluid as recommended.
Use cold weather hydraulic oil as recommended in the
machine General Specifications in temperatures of -12°C
(10°F) or below.
Hydraulic System Warm-Up Switch
This system may be used to warm the hydraulic fluid when
the ambient temperature is below 0°C (32°F) and boom
movement is sluggish because of cold fluid.
There may be a toggle switch for the warm-up system
on the lower control panel and/or one on the front of the
upper control panel.
The engine must be running and the switch used to turn
the system on must be at the same location that the en-
gine was started. For example, if the engine was started
from the lower controls, the warm-up switch at the lower
controls must be used for the system to operate.
To operate the warm-up system:
1. Start the engine.
2. From the same control station that the engine was
started, place the warm-up switch in the on position.
The engine throttle speed will increase while the
warm-up system is on.
3. After the hydraulic fluid has been warmed to operat-
ing temperature and the throttle speed returns to idle,
place the warm-up switch in the off position.
Manually Warming The Hydraulic System
The hydraulic oil may be warmed by bottoming out the
boom extension cylinder. Raise the main boom so it is
horizontal and operate the boom retract function while the
machine is stowed. With the cylinder bottomed out the oil
flow will produce heat to warm the hydraulic oil.
Caution
Not all hydraulic fluid is suitable to use in the hydrau-
lic system. Some have poor lubricating character-
istics and may increase component wear. Only use
hydraulic fluid as recommended.
Use cold weather hydraulic oil as recommended in the
machine General Specifications in temperatures of -12°C
(10°F) or below.

Operation
16 A46JRT – 0260999
Preparing for Operation
Use the following procedure to prepare the aerial platform
for operation.
1. Perform a prestart inspection as described in the
“Daily Preventative Maintenance Checklist” on page
23.
2. Place the battery disconnect switch in the on posi-
tion.
3. Close and latch the cowling doors.
Lower Controls
The lower controls override the upper 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 for testing and
inspection.
Use the following procedure to operate boom, turntable,
or platform functions using the lower controls (ref: Figure
3 on page 7).
1. Pull the emergency stop button outward and place
the control selector switch in the lower control posi-
tion. The engine starts to preheat when the switch is
placed in the lower control position. Wait ten seconds
for the engine to preheat, if required.
2. Press and hold the start button until the engine starts,
then release.
3. Let the engine warm to operating temperature.
4. Hold the ground operation switch in the on position
while operating the boom and turntable control toggle
switches.
Note
If a machine function is not operated within 10 seconds
of activating the ground operation switch, no functions
will operate until the switch is released and again placed
in the enable position.
5. Hold the appropriate toggle switch in the desired
direction.
6. Release the function toggle switch to stop move-
ment.
7. Place the ground operation switch in the off position
when no functions are being operated.
Upper Controls
The upper controls may be used for driving the aerial
platform and positioning the booms and platform while
on the job.
Use the following procedure to operate machine functions
using the upper controls (ref: Figure 4 on page 7).
1. At the lower controls, place the emergency stop
switch in the on position and place the controls switch
in the platform position.
2. Enter the platform and securely close the gate.
3. Attach the fall restraint lanyard to one of the anchor
points.
4. Pull the emergency stop outward.
5. Turn the start switch to the on position and pause a
few seconds while the alarm sounds to alert others
that the machine is about to start. Wait ten seconds
for the engine to preheat, if required.
6. Turn the switch to start, then release it to on. The en-
gine will not start if the switch is left in the on position
for 30 seconds or longer before turning it to start. The
switch must be turned back to off before the engine
will start.
7. Let the engine warm to operating temperature.
Boom Operation
Use the following procedure to operate the turntable,
boom, or platform functions.
1. Step down on the platform foot switch. This switch
must be held down to operate the upper controls.
Note
If a machine function is not operated within 10 seconds of
activating the foot switch, no functions will operate until the
switch is released and again placed in the enable position.
2. Hold the appropriate control in the desired direction.
Always look in the direction of movement.
3. To stop movement release the control to its neutral
position or release the foot switch.
Driving and Steering
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. Do not drive an elevated aerial platform on
soft, uneven, or sloping surfaces. Do not drive the
machine on grades that exceed 40 percent.
For operation on grades up to 40 percent, it is recom-
mended that the main boom be near horizontal and the
jib be elevated just enough to provide adequate ground
clearance.

Operation
A46JRT – 0260999 17
A 40 percent grade is a 1.2 m (48″) vertical rise in
3.05 m (10′) horizontal length.
Avoid driving with the platform over the front end of the
chassis. In this position the machine is difficult to control
because:
• Drive and steer control movements and their resulting
machine movements are reversed.
• When driving fast, sudden turns or stops produce
more severe reactions to platform occupants.
• More turning space is required to prevent the platform
from colliding with obstacles several feet beyond the
path of the tires.
Warning
Death or serious injury could result from improperly
driving or steering the aerial platform. Read and un-
derstand the information in this manual and on the
placards and decals on the machine before operating
the aerial platform on the job.
The blue and yellow arrows on the chassis indicate the
direction the chassis will move when the drive or steer
control is moved toward the corresponding color.
When the machine is in the stowed position, with the
booms centered between the rear wheels, the direction
of drive and steer control movement corresponds with
the direction of chassis movement.
When the turntable is rotated from the stowed position,
with the booms to either side of or in front of the chassis,
the direction of control movement does not correspond
with the direction of chassis movement.
• To avoid confusion, always drive to the work area
or move between work areas with the turntable and
booms in the stowed position.
• After arriving at the work area, the booms may be
positioned to the side or the front of the chassis for
nal positioning.
• Always look in the direction of movement as indicated
by the directional arrows on the chassis.
Use the following procedure to operate the drive and
steer functions.
1. Determine the desired drive range for the specific
driving conditions. Place the switch in the appropriate
position to achieve the desired drive wheel opera-
tion.
• Use high range (rabbit) when traveling across rm,
at, level surfaces. High range can only be activated
when the booms are stowed. High range is for high
speed, low torque operation.
• Use low range (turtle) for driving on loading ramps or
other steep grades and when safety considerations
demand slow deliberate machine movement. Low
range is for low speed, high torque operation.
2. Step down on the platform foot switch.
3. Push the drive joystick forward to move the chas-
sis forward, the direction of the blue arrow. Pull the
joystick backward to move the chassis backward,
the direction of the yellow arrow. The drive speed is
proportional to the joystick position.
4. To stop drive motion, return the joystick to neutral.
5. The steer switch is a momentary contact, rocker
switch on top of the drive joystick. This switch controls
the two front wheels to steer the aerial platform.
• To steer to the right, hold down the right side of the
steer switch.
• To steer to the left, hold down the left side of the
steer switch.
Note
The steering wheels are not self-centering. Set the steer-
ing wheels straight ahead after completing a turn.
6. After driving to the desired location, release the foot
switch, or push the emergency stop button to apply
the parking brakes.
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 and shift the drive system to low range
before traveling over rough terrain or any sloped surface.
Drive speed ranges are interlocked through limit switches
that sense the main and riser boom position.
• When either boom is elevated or extended, only the
slowest drive speed will work regardless of the drive
range switch position.
• To avoid a sudden speed change from high to low
elevated boom speed, always bring the machine
to a stop before raising the booms from the stowed
position.
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
1.28 km/h (0.8 miles per hour) [10.6 m (35 feet) in
30 seconds] when any of the booms are out of the stowed
position.

Operation
18 A46JRT – 0260999
Pivoting Front Axle
When the machine is in the stowed position, with the
booms lowered and retracted, the front axle pivots to keep
all four wheels in contact with the ground surface.
While driving between work site, the pivoting axle:
• Improves traction
• Reduces ground pressure
When the main or riser boom is raised from its rest, the
axle locks into position to maximize the stability of the
machine while the platform is elevated.
Snorkel Guard Override Switch
When the Snorkel Guard system is activated, the Snorkel
Guard override switch (refer to Figure 4 on page 7) is used
to override the system to operate main boom down, riser
boom down, or jib down functions. The switch is spring
returned to the normal operation position.
Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury could result from such accidents. The Snorkel
Guard override switch must only be used when all
controls are released and in the neutral position. If
a zero or neutral state cannot be achieved, depress
the emergency stop and obtain assistance at the
lower controls.
1. When machine is stopped due to activation of the
Snorkel Guard system, immediately depress the
emergency stop, release the foot switch and all con-
trols. Perform an assessment of the situation which
caused the system to activate.
2. If it is determined that all controls are released and
operation can proceed, return the emergency stop
to the on position, and activate the Snorkel Guard
override switch.
3. Activate the foot switch.
4. Activate the necessary functions to move the platform
away from the obstacle that caused the Snorkel
Guard activation.
5. Assess the machine for any damage. If damage
occurred, return to the stowed position, exit the unit
and perform a thorough inspection before returning
to service.
Drive Motion Alarm
A drive motion alarm sounds loud intermittent beeps
anytime the machine drive functions are being operated.
Electrical Power Outlet
Power may be supplied to the outlet using an external
power source or by operating the optional AC generator.
To use the outlet, plug a source of power into the power-
input connector on the right side of the chassis. Unplug
the source of power before moving the aerial platform.
AC Generator
The optional generator supplies power to the electrical
outlet only when the engine is running and the machine
is stationary. The machine functions will not operate when
the generator switch is in the generator position.
Caution
Cold hydraulic oil does not flow well and may produce
improper generator output voltage. Improper outlet
voltage can damage some electrical power tools and
equipment. Warm the hydraulic oil before operating
the generator.
Do not operate the generator unless the hydraulic oil is
at operating temperature. Refer to “Cold Weather Start-
Up” on page 15 for a hydraulic oil warm-up procedure.
To supply power to the electrical power outlet, start the
engine and place the generator switch in the generator
position.
The engine will run at high idle while the generator is
operating. The generator will continue to operate as long
as the engine is running and the switch is in the genera-
tor position.
Air Line
The optional air line may be used to conduct air for tool
operation at the platform.
• The input connector is at the rear of the chassis and
the output connector is at the platform on the rotator
guard.
• The maximum working pressure of the line is
1,723 kPa (250 psi).
The air line may be used to conduct fluids such as water
or antifreeze. Contact Snorkel for compatibility information
before using the air line to conduct other fluids.
Caution
Fluid in the air line may damage some air tools or
freeze and damage the line. Drain and blow out the
air line after using it to conduct fluids.
Use the following procedure to drain the air line.
1. Close the input connector on the chassis.
2. Open the output connector at the platform.
3. Raise the riser and main booms slightly above hori-
zontal.
