OPERATOR’S

MANUAL

Part Number 0181972

March 2014

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 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, booms, 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, booms, 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.

The aerial platform may be operated from either the lower or upper controls.

Danger

Chapter 8 – Operation

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 ANSI.

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 accident. Operate the aerial platform on a firm, flat, level surface. Avoid travel speeds and/or rough ter rain 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.

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 32°F (0°C) or below, the engine and hydraulic system oil may need to be warmed up 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. The engine may be equipped with an optional cold weather start kit.

Cold, thick hydraulic oil does not flow well and may cause delay in response to control movement and improper voltage output of the optional AC generator. Cold hydraulic oil may also cause cavitation and pump damage. The hydraulic system may be equipped with an optional cold weather warm-up kit.

Engine Cold Weather Start Kit

The optional engine cold weather start kit may be an engine block heater or a radiator hose in-line heater. The type of starting assist system depends on the engine manufacturer.

Note:

Machines equipped with a Hatz engine do not have an optional engine cold weather start kit.

Refer to the engine manufacturer below for specific cold weather start-up information for that particular engine type and cold weather start system.

Continental, Cummins and Ford — Block Heater

Plug the heater cord into a 125 Volt AC, 600 watt source eight hours before starting the engine. The heater will warm the engine block to make cold weather starting easier.

Unplug the power cord before starting the engine.

General Motors — Radiator Hose In-Line

Plug the heater cord into a 125 Volt AC, 600 watt source eight hours before starting the engine. The heater will warm the water in the lower radiator hose to make cold weather starting easier.

Unplug the power cord before starting the engine.

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 hy draulic system. Some have poor lubricating charac -

AB60J – 0181972 45

Chapter 8 – Operation teristics and can increase component wear. Only use hydraulic fluid as recommended.

Use cold weather hydraulic oil as recommended in the machine General Specifications in temperatures of 10°F

(-12°C) or below.

Hydraulic System Warm-up Switch

This system may be used to warm the hydraulic fluid when the ambient temperature is below 32°F (0°C) 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 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.

To operate the warm-up system:

1. Start the engine and place the engine throttle in the low position.

2. From the same control station that the engine was started, place the warm-up switch in the on position.

3. After the hydraulic fluid reaches 50°F (10°C) as indi cated on the thermometer, 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 hy draulic system. Some have poor lubricating charac teristics and can increase component wear. Only use hydraulic fluid as recommended.

Use cold weather hydraulic oil as recommended in the machine General Specifications in temperatures of 10°F

(-12°C) or below.

A 20 percent grade is a 24″ (61 cm) vertical rise in 10′

(3.05 m) 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 can 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 final 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 operation.



Use high range when traveling across firm, flat, level surfaces. High range can only be activated when the booms are stowed. High range is for high speed, low torque operation.

48



Use low range 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. The drive speed is proportional to the joystick position.

• 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.

4. To stop drive motion, return the joystick to neutral.

5. The drive joystick controls the two front wheels to steer the aerial platform.

• Push the drive joystick to the right to steer to the right, the direction of the yellow arrow.

• Push the drive 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 switch the drive system to low range before traveling over rough terrain or any sloped surface.

Drive speed ranges are interlocked through a limit switch that senses the main boom position.



When the boom is elevated, 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.

AB60J – 0181972

Do not use the aerial platform if it drives faster than

0.6 mph (1 km/h), or 26 feet (8 m) in 30 seconds, when the booms are elevated from the stowed position.

Gradeability

Machine gradeability refers to the maximum slope that the aerial platform is capable of travel under practical conditions. It is based on mathematical calculation, but it also takes into account the practical application.

At any given moment when driving the machine on a slope, at least one, if not all, of the factors contributing to achieving theoretical gradeabilty will not be at optimal performance. For example, tire contact may not be the same at each drive wheel or the slope conditions may not be optimal, which would then allow for loss of traction.

Percent vs. Degree of Slope

Gradeability is most often referenced as a percentage.

That value is based on a slope angle of 45° representing

100% grade.

Angle indicators, or inclinometers, often measure the angle of the slope in degrees not the percent slope.

Because of that, it may be useful to understand the relationship between percent slope and the degree of the slope angle as shown in Figure 8.5.

Chapter 8 – Operation

Driving on a Slope

The machine should only be driven on a slope or loading ramp in the stowed position with the platform on the downhill side.

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 on slopes that exceed 20 percent grade, or where conditions of the slope could cause driving to be hazardous.

Place the drive speed in the low position before attempting to drive the machine on a slope.

Drive the aerial platform only on slopes, or loading ramps that are within the 20 percent grade capability of the aerial platform.

Calculate the percent grade:

 before attempting to climb an unknown grade

 if it is believed that there is a malfunction to determine if the slope is within the actual grade capability of the aerial platform.

The percent grade equals the height (rise) of the slope di vided by the length (run) times 100. Refer to Figure 8.6.

Length

Height

% of Grade =

Height

Length x 100

Figure 8.6 – Percent Grade Formula

The grade can be measured with an inclinometer or by using a tape measure, a level, and a straight 2 x 4. If using an inclinometer, refer to the conversion diagram if necessary.

To measure the grade without an inclinometer, use the following procedure.

1. With the 2 x 4 laying parallel with the slope, lay the level lengthwise on the 2 x 4.

2. Holding the downhill end, raise the 2 x 4 until the level indicates that the board is level (refer to Figure

8.7).

All Motion Alarm

The optional all motion alarm sounds loud intermittent beeps anytime the machine functions are being operated.

Four Wheel Drive

The machine may be equipped with a four wheel drive system. This system operates full time and requires no action by the operator.

Four wheel drive machines have a “4x4” decal on each side of the chassis and all four of the wheel hubs are drive hubs and look the same.

Electrical Power Outlet

The electrical outlet at the platform has 2, 3-prong, 110 volt AC electrical connectors. Their combined output is limited by a 15 amp circuit breaker.

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 located inside the rear of the turntable

(refer to Figure 8.8). Unplug the source of power before moving the aerial platform.

Record the height distance.

4. Measure the length of the 2 x 4 and record this measurement.

5. Use the formula in Figure 8.6 to calculate the percent of the grade.

Machine Gradeability

The gradeability specification for the AB60J/AB60JRT aerial platforms is 20%. An actual gradeability of 20%, indicates that in most normal working conditions the machine can be driven on a slope with an angle of 11.3 degrees.

3. Raise the riser and main booms slightly above horizontal.

4. Open the input connector on the turntable.

5. Allow the fluid to drain from the line.

6. Lower the boom and close both connections.

Driving Lights

The optional driving lights are for use in dimly lit areas and are not intended for driving on public roadways. The machine may have two lights at the front of the turntable or four lights, two at the front and two at the rear of the turntable.

The lights are operational when the machine is set up for operation from the upper controls and the light switch is turned on.

If the engine is running, the idle speed increases when the driving lights are turned on.

Note

Working with the driving or platform work lights on, while the engine is off, can discharge the batteries enough that the engine will not start or the emergency power system will not operate. If the engine cannot be left running while the lights are on, start and run the engine for at least 15 minutes each hour .

Platform Work Lights

The optional platform work lights are located on the top rail of the platform next to the upper controls (refer to Figure

8.10). The direction a light points can be adjusted by using two ½″ wrenches to loosen the clamp below the light.

Figure 8.10 – Upper Controls

51

Chapter 8 – Operation

The lights are operational when the upper controls emergency stop button is pulled up and the start switch is turned on.

The engine speed increases to high idle when the platform work lights are turned on.

Note

Working with the platform work lights on, while the engine is off, can discharge the batteries enough that the engine will not start and the emergency power system will not operate. If the engine cannot be left running while the lights are on, start and run the engine for at least 15 minutes each hour.

Platform Glazier Package

The glazier package allows the platform operator to position glass at the work place. Refer to the Glazier Package manual (Snorkel Part Number 0421269) for information on proper use of the glazier package.

The package includes two lined trays with keeper pins, platform rail padding, and tie-down straps with protectors

(refer to Figure 8.11) .

Bumpguard System

The optional bumpguard system is a spring mounted padded railing below the platform. There are two infrared lights mounted along the bottom of the platform next to two infrared sensitive switches. The lights shine on reflectors on the bumpguard system and are reflected back to the switches.

If the bumpguard comes into contact with a stationary object, the bumpguard moves and one or both of the light beams is broken. A dark switch removes control from the platform control box, immediately stopping all platform movement.

To override the bumpguard infrared switch, in order to move away from the stationary object, do the following:

1. At the upper controls, hold the proximity override switch up.

2. Use the controls on the upper control box to move the platform away from the stationary object.

3. Return the proximity override switch to normal operation.
