Special Limitations
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 maximum platform capacity for the aerial platform is stated in
the “Specifications” on page 23.
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.
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 accident. 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.
Beaufort Scale
Never operate the machine when wind speeds exceed
12.5 m/s (28 mph) [Beaufort scale 6]. Refer to Figure 1.
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 controls, 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.

Operation
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 inadequate 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 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 will 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. 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 personnel and equipment that may be lifted in the platform.
Hydraulic System Cold Weather Warm-Up
Some machines may have a hydraulic fluid warm-up
system that will automatically warm the fluid upon activating 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 hydraulic system. Some have poor lubricating characteristics 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 engine 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.
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 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.
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.
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 operating 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 hydraulic system. Some have poor lubricating characteristics 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.

A46JRT – 0260228 15
Operation
Driving and Steering
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over accident. 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 recommended that the main boom be near horizontal and the
jib be elevated just enough to provide adequate ground
clearance.
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.
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 operation.
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 chassis 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.
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 understand 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.
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 steering 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.
16 A46JRT – 0260228
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
To supply power to the electrical power outlet,
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 generator position.

the output connector is at the platform on the rotator
guard.
start the
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.
All Motion Alarm
The optional all motion alarm sounds loud intermittent
beeps anytime the machine 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 powerinput 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.
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.
