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.
The work platform is NOT intended to be driven over uneven, rough, or soft terrain.
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 lbs) of force per occupant, with a maximum of 400 N (90 lbs) for two occupants.
The system will remain in error mode until the excess load is removed from the platform and the emergency stop button or start switch is cycled off and back on, resetting the system. At that time, the machine functions are 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 or if the system is in error mode and can not be reset, the emergency power system may still be used for emergency machine operation from either the lower or 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.
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.
Danger
DO NOT exceed the maximum amount of manual
chine operation, there is a five second delay in machine functions following:

A62JRT – 104850-000 13
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.

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 the percent grade­ability of that particular machine.
For operation of A62JRTJ machines on grades up to 45 percent, it is recommended that the main boom be near horizontal to provide adequate ground clearance.
A 45 percent grade is a 1.4 m (54″) 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.
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 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.
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.
4. To stop drive motion, return the joystick to neutral.
5. Push the drive joystick to the right to steer to the right, the direction of the yellow arrow. Push the joystick to the left to steer to the left, the direction of the blue arrow.
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 tip 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 el-
• evated boom speed, always bring the machine to a stop before raising the booms from the stowed position.

Operation
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 in high or mid speed when the main boom is above horizontal or the tip boom is extended.
Pivoting Front Axle
The front axle pivots to maximise tire contact with the ground. This helps to optimize both traction and machine stability.
The axle has the ability to pivot when either the ground operation switch is engaged at the lower controls, or when the foot switch at the upper control station is engaged.
While driving between work sites, the pivoting axle:
Improves traction
• Reduces ground pressure
•
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.

• 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 booms slightly above horizontal.
4. Open the input connector on the chassis.
5. Allow the fluid to drain from the line.
6. Lower the boom and close both connections.
Emergency Lowering
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 14 for a hydraulic oil warm-up procedure.
