Electrical Hazard Warning

DANGER

THE SNORKELIFT AERIAL WORK PLATFORM

IS NOT ELECTRICALLY INSULATED.

If the platform, booms, or any other conductive part of a Snorkelift contacts a high-voltage electrical conductor, the result can be SERIOUS INJURY or DEATH for persons on or near the machine.

GO NO CLOSER THAN THE MINIMUM SAFE APPROACH DISTANCES

(M.S.A.D) - AS OUTLINED IN TABLE 1. AND FIGURE 3.,

ON THE NEXT PAGE.

Be sure to allow for sag and sway in the wires and the work platform.

If a Snorkelift comes in contact with a live electrical conductor, the entire machine can be charged.

If that happens, you should remain on the machine and not contact any other structure or object within reach. That includes the ground, adjacent buildings, poles, and any object not a part of the Snorkelift.

Such contact could make your body a conductor to the other object creating an electrical shock hazard resulting in SERIOUS INJURY or DEATH.

DO NOT attempt to enter or leave the Snorkelift until you are sure the electricity has been turned off.

If a Snorkelift is in contact with a live conductor, the platform operator MUST warn others on the ground in the vicinity of the Snorkelift to STAY AWAY from the machine, since their bodies can also form a path for electricity to ground thus creating an electrical shock hazard with possible ELECTROCUTION and DEATH.

DO NOT attempt to operate the Snorkelift ground controls when the platform, booms, or any other conducting part of a Snorkelift is in contact with electrical wires or if there is an immediate danger of such contact.

Regard all conductors as energized.

Personnel working on or near a Snorkelift must be continuously aware of electrical hazards, recognizing that SERIOUS INJURY or DEATH can result if contact with an electrical wire does occur.

Safe Operation

The following safety information is vitally important for safe operation of the AB46J. Failure to follow these instructions can result in personal injury or DEATH.

Pre-start Inspection

❑

Prior to each shift, the AB46J shall be given a visual inspection and function test. See the “Daily Inspection and Maintenance” chapter 7, in this manual for a list of items to inspect and test.

CAUTION

1. Safety

When moving the platform, check the clearance around the AB46J to avoid contact with structures or other hazards. Always look in the direction of motion.

Keep ground personnel from under the platform when the platform is raised.

Secure all accessories, containers, tools, and other materials in the platform to prevent them from accidentally falling or being kicked off the platform.

Remove all loose objects stored in or on the machine, particularly in the platform. Remove all objects which do not belong in or on the machine.

DO NOT operate the AB46J unless you are TRAINED and AUTHORIZED, understand the operation characteristics of the AB46J, and have inspected and tested all functions to be sure they are in proper working order.

Work Place Inspection and Practices

❑

Before the AB46J is used, and during use, check the area in which the AB46J is to be used for possible hazards such as, but not limited to:

1. Drop-offs or holes.

2. Side slopes.

3. Bumps and floor obstructions.

4. Debris.

5. Overhead obstructions and high voltage conductors.

6. Hazardous locations.

7. Inadequate surface and support to withstand all load forces imposed by the aerial platform in all operating configurations.

8. Wind and weather conditions.

9. Presence of unauthorized persons.

10. Other possible unsafe conditions.

Before the AB46J is used, determine the hazard classification of any particular atmosphere or location according to ANSI/NFPA 505-1987.

Any AB46J operated in a hazardous location must be approved and of the type required by ANSI/NFPA 505-1987.

DO NOT engage in any form of “horseplay” or “stunt driving” while operating the AB46J.

DO NOT permit riders on the machine anyplace other than on the platform.

When other moving equipment is in the area, take special precautions to comply to local regulations regarding warnings.

Never steady the platform by positioning it against another platform.

DO NOT operate an AB46J that is not functioning properly, or has been damaged, until the machine has been repaired by a qualified maintenance person.

DO NOT operate an AB46J that does not have all its Decals and Placards attached and legible.

Drive the machine with care and at speeds compatible with conditions. Use extra caution when driving over rough ground, on slopes, and when turning.

Know and understand the job site traffic flow patterns and obey the flagmen, road signs, and signals.

Watch for bystanders and never allow anyone to be under, or to reach through, the machine and its equipment while operating.

Use the recommended transport device when loading the machine.

A recommended safety practice is to have personnel that are trained in the operation of the emergency controls working in the immediate area of the AB46J to assist the platform operator in the event of an emergency.

AB46J – 0163187 page 1 - 1

1. Safety

Electrocution

❑

The AB46J is an all metal boom, NONINSULATED, aerial work platform. DO NOT operate it near ELECTRICAL conductors. Regard all conductors as being energized.

DO NOT operate outside during a thunderstorm.

Tipover and Falling Hazards

❑

DO NOT operate an AB46J from a position on trucks, trailers, railway cars, floating vessels, scaffolds, or similar equipment unless the application is approved in writing by Snorkel.

If the platform or elevating assembly becomes caught, snagged, or otherwise prevented from normal motion by an adjacent structure or other obstacles such that control reversal does not free the platform, remove all personnel from the platform before attempts are made to free the platform using ground controls.

The guardrail system is your primary fall protection. Never operate without all parts of the guardrail system in place and the gate closed.

Under normal working conditions it is best not to transfer from the platform to another structure or vice versa, unless that is the safest way to do the job. Each situation must be judged separately taking the work environment into account. The following guidelines apply:

1. Where possible, place the work platform over a roof or walking structure to do the transfer.

2. Transfer your anchorage from one structure to another before you step across.

3. Remember, you might be departing the work platform to a structure where fall arrest is required.

DO NOT climb the rails. Use the entrance.

Maintain a firm footing on the platform floor. Climbing on the guardrails is prohibited.

DO NOT use ladders, planks, or other devices to extend or increase your work position from the platform.

All platform occupants MUST use fall restraint. Attach fall restraints to the platform anchorage points.

DO NOT exceed the unrestricted platform capacity as indicated on the capacity placard on the platform.

DO NOT raise the boom if the AB46J is on soft ground. Operate the boom only on a firm surface capable of withstanding all load forces imposed by the aerial platform in all operating conditions.

Raise the platform only when the AB46J is on level ground.

DO NOT carry loads from any point outside of the platform.

Care shall be taken to prevent rope, electric cords, and hoses, etc., from becoming entangled in the aerial platform.

DO NOT jerk the controls. Move the controls slowly and deliberately to avoid jerky and erratic operation. Always stop the controls in the neutral, off, position before going in the opposite direction.

DO NOT use the boom for any purpose other than to position personnel, their tools, and materials.

DO NOT use the AB46J as a crane, hoist, or jack.

DO NOT operate the AB46J in winds, or wind

gusts, of 28 mph (45 km/h) or more.

DO NOT add anything to the AB46J that will increase the wind loading ( banners, flags, etc.).

Crushing

❑

Always look in the direction of travel. Avoid overhead obstructions.

Never cover the floor grating or otherwise obstruct your view below.

Make sure the area below the platform is free of personnel before lowering.

■

General Safety Precautions

❑

Personnel Precautions

If you encounter any suspected malfunction of the aerial platform, or any hazard or potentially unsafe condition relating to capacity, intended use, or safe operation, cease operation and seek assistance from management.

❑

Operator General Precautions

Make sure that all protective guards, cowlings, and doors are in place and secure.

Be sure the guardrail system, including the gate, is in place and secure.

❑

Mounting and Dismounting Precautions

Use three points of support when getting on or off the platform (e.g., two hands and one foot).

Keep the platform clean.

DO NOT jump off the machine.

DO NOT dismount while the machine is in motion.

page 1 - 2 AB46J – 0163187

Starting and Stopping Precautions

❑

DO NOT start until all personnel are clearly away from the machine.

Before leaving the operator’s station, place the machine in the stowed position.

When leaving the machine parked or unattended, remove the starter key from the Master Switch, set the Battery switch to OFF, then lock the

Battery switch.

Operating Precautions

❑

DO NOT modify the AB46J in any way.

When parts or components are replaced, they shall be identical or equivalent to original Snorkel parts or components.

DO NOT override any of the safety features of the AB46J.

Limit travel speeds according to conditions. Take into account: grade, surface, congestion, visibility, side slope, location of personnel, and other hazards.

Operator Maintenance Precautions

❑

Charge batteries in a well-ventilated area free of flame, sparks, or other hazards that might cause fire or explosion.

1. Safety

■

Safety Decals and Placards

There are several safety decals and placards on the AB46J. Their locations and descriptions are shown in this section. Take time to study them.

CAUTION

Be sure that all the safety decals and placards on the AB46J are legible. Clean or replace them if you cannot read the words or see the pictures. Clean with soap & water and a soft cloth. DO NOT use solvents.

You must replace a decal or placard if it is damaged, missing, or cannot be read. If it is on a part that is replaced, make sure a new decal or placard is installed on the replaced part. See your Snorkel dealer for new decals and placards.

Refer to Placards and Decals Inspection Chart and drawing in the “Daily Inspection and Maintenance” chapter 7, for part numbers, location, and required quantities of all placards and decals.

Lead-acid batteries contain sulfuric acid. Sulfuric acid will damage your eyes or skin on contact. When you work around lead-acid batteries, wear a face shield to avoid getting acid in your eyes. Wear rubber gloves and protective clothing to keep acid off your skin. If acid contacts your eyes, flush immediately with clear water and get medical attention. If acid contacts your skin, wash off immediately with clear water.

CAUTION

DO NOT use your hand to search for hydraulic

oil leaks. High pressure hydraulic oil can easily cut and penetrate your skin-averyserious injury that requires immediate attention by a medical specialist trained in that type of injury. Use a piece of cardboard or wood to search for hydraulic oil leaks.

DO NOT attempt repairs unless you are trained. Refer to manuals and experienced repair personnel for help.

2. Safety Devices

■

Safety device information

For emergency operation controls and procedures, see the “Emergency Operation” chapter 9, in this manual.

The devices listed in this chapter are safety devices. They are on an AB46J to increase safety in the work place for both the operator and other people near an AB46J. DO NOT by-pass, disable, modify, or ignore any of these devices. Check them carefully at the start of each work shift to see that they are in working order (see “Daily Inspection and Maintenance” chapter 7). If any is found to be defective, immediately remove the AB46J from service until a qualified service technician can make repairs.

Emergency Power Battery

❑

Emergency stop switches

❑

At the ground control box: Press the large red Emergency Stop button in, at any time, under any conditions, and the entire machine stops, the drive motors and pump turn off, the brakes automatically set, and nothing moves. This switch must be pulled out (on) for anything to work.

The emergency power battery powers the emergency operating circuits. If the platform is aloft when regular power fails, emergency battery power is the only way to lower the platform, there is no manual bleed down procedure.

Thus, maintenance of the emergency power battery is very important. The emergency power battery should always be kept at full charge and the battery terminals kept free of corrosion.

AB46J – 0163187 page 2 - 1

At the platform control box: Press the large red Emergency Stop button down (off) and the entire machine stops, the drive motors and pump turn off, the brakes automatically set, and nothing moves. This switch must be pulled to its up (on) position to control the AB46J from the platform.

The ground control box will override the platform control box. If the platform control box Emergency Stop button is down (off) the ground control box can still be used to start and operate the AB46J.

2. Safety Devices

Flashing Lights

❑

GFCI (Ground Fault Circuit Interrupt)

❑

The optional flashing lights alert people that the AB46J is present. The lights flash at about one flash per second any time the Battery switch, Master Key Switch, and the Emergency Stop switch (at the ground) are all ON. There is no ON/OFF switch for the flashing lights.

Platform Foot Switch

❑

The platform foot switch prevents the platform from moving if something accidentally pushes one of the platform moving controls on the platform control box. (Stepping on the foot switch is an action that must be performed, at the same time as another action, to make the platform move.)

The (GFCI) ground fault circuit interrupt is located near the platform control box. To use the outlets, connect the power input connector, on the top rear of the chassis, to a source of 125 volt AC, 15 A electrical power.

The GFCI protects against electricity flowing to ground. When electricity flows to ground the GFCI shuts off power to the electrical outlets.

To reset the outlets:

1. Unplug the equipment being used.

2. Press the RESET button on the GFCI.

This should restore power to the outlets. If it does not, unplug the source of power and refer the problem to a trained service technician.

❑

Platform Gravity Gate

DANGER

Serious Injury can result from sudden stops.

To avoid sudden stops, Do Not remove your foot from the foot switch while the AB46J is in motion.

page 2 - 2 AB46J – 0163187

The platform gravity gate is the place in the platform guardrail system where you should enter and leave the platform. Raise the gate and step under it onto the platform. Once you have entered the platform and attached your fall restraint lanyard to an anchor point, check to see that the gravity gate has fallen back into place.

Ground Operation Switch

❑

The Ground Operation switch prevents the platform from moving if something accidentally pushes one of the platform moving switches at the ground control box.

2. Safety Devices

Operator Horn

❑

The operator horn is used primarily to get the attention of people on the ground when you are working aloft.

For the horn to work the Battery switch must be ON and the following switches, on the ground control box, must be set as indicated:

Platform/Ground Selector . . . . . . PLATFORM

Emergency Stop . . . . . . . . . . . . . . . Pulled Out

Master Key Switch . . . . . . . . . . . . . . . . . . . ON

Pushing the Ground Operation switch is an action that MUST be performed, at the same time as another action, to make the platform move.

❑

Platform Guardrails

The platform guardrails help protect you from falling off the platform. Be sure the guardrails are properly installed and that the gate is in place.

Lanyard Anchor Points

❑

All personnel on the platform should attach their fall restraint lanyards to one of the lanyard anchor points.

AB46J – 0163187 page 2 - 3

2. Safety Devices

Level Sensor

❑

The level sensor detects how far out of level the turntable is. If the turntable gets over 5° out of level the level sensor activates the tilt alarm (described in this chapter).

Motion Warning Alarm

❑

The optional motion warning alarm emits a loud beeping sound, at ground level, anytime the Drive/Steer controller is in FORWARD or REVERSE or anytime the booms move. This alarm alerts people on the ground that the AB46J is traveling along the ground.

❑

Platform Swinging Gate

Tilt Alarm

❑

The tilt alarm warns the AB46J operator that the AB46J is over 5° out of level.

If the tilt continues to increase, the AB46J will eventually tip over.

CAUTION

When you hear the loud two toned alarm, (high-low-high-low...), immediately retract and lower the platform. When the platform is completely down, determine and correct the cause of the tilt before raising the platform again.

The optional platform swinging gate is designed to automatically close after you enter or leave the platform.

It helps prevent people from falling off the platform.

The hour meter gauge cannot be reset. Use it to tell when it is time to perform the periodic maintenance listed in the Maintenance Manual.

Hydraulic Oil Filter

❑

The hydraulic oil filter gauge (1) is located above the hydraulic oil filter (2). The gauge measures pressure into the filter. As the filter clogs, the pressure goes up.

Check the condition of the filter, at the start of each work shift, according to the procedure described in the “Daily Inspection and Maintenance” chapter 7, in this manual.

The Hour Meter gauge is basically an electric clock. It accumulates time when any part of the AB46J is in motion. Time will accumulate when the following conditions occur simultaneously:

4. Gauges, Circuit Breakers and Displays

Hydraulic Oil Level

❑

The hydraulic oil level gauge (1) is on the side of the hydraulic oil tank (2).

Hydraulic Oil Temperature

❑

The hydraulic oil temperature gauge measures the temperature of the oil in the tank. The temperature should not exceed 200°F (93°C).

If the temperature reaches its limits, reduce your driving speed or stop the AB46J and let the hydraulic oil cool.

■

Circuit Breakers

With the exceptions of the optional GFCI outlet at the platform and the circuit breaker on the battery charger, there are no other circuit breakers on an AB46J that are accessible to an operator.

The gauge shows the actual level of oil inside the tank.

Read it only when the booms are completely down and completely retracted. Otherwise, the boom hydraulic cylinders become large reservoirs for hydraulic oil and the oil level in the tank will be low. The oil level (3) should be between the high mark (4) and low mark (5).

All of the other circuit breakers on an AB46J automatically reset themselves about one minute after they trip.

When a circuit breaker trips that will not reset, or if it resets automatically but trips again, immediately attempt to lower the platform to the ground by using normal operating procedures.

If normal procedures do not work, use emergency procedures see “Emergency Operation” chapter 9, to lower the platform.

If the cause of the problem is not immediately obvious, refer the problem to a qualified service technician.

■

Batteries

The following information about battery care and maintenance was supplied by Interstate Batteries and is reprinted here with their permission.

1. New batteries need to be cycled several times before reaching full capacity (20-50 cycles, depending on type). Use should be limited during this period.

2. Always fully recharge batteries immediately after use. Batteries perform best when they are fully charged. More capacity and longer life will result from this practice.

3. The deeper the discharge, the fewer number of cycles a lead/acid battery will deliver. Deep discharges deteriorate the battery quicker than lighter shallow cycles.

4. Battery cables should be intact, and connectors kept tight at all times. Systematic inspection is recommended.

5. Vent caps should be kept in place and tight during vehicle operation and battery charging.

6. Batteries should be kept clean - free of dirt and corrosion - at all times. Always keep the top of batteries clean. A film on top of the battery can cause the current to migrate between the posts, accelerating self discharge.

7. Never let the electrolyte level of a lead-acid battery fall below the plates. Lack of maintaining the electrolyte in a lead-acid battery causes damage to the exposed portion of the plate which reduces capacity.

8. Always check electrolyte level before charging. Do not add water to individual cells unless plates are exposed. Batteries should be watered after charging unless the plates are exposed before charging. If exposed before charging, the plates should be covered by approximately 1/8” of water. Check water level after charging. Water should be kept 1/4” (6 mm) below the bottom of the fill tube in the cell cover.

9. Water used to replenish batteries should be distilled or treated to not exceed 200 T.D.S. (total dissolved solids... parts per million). Particular care should be taken to avoid metallic solids (iron).

5. Batteries and Battery Charging

10. Always allow batteries to cool off after charging. The cooling time is very important because heat is generated during the recharge and discharge cycles. Without the cooling time the heat grows, accelerating grid corrosion which is one of the major causes of battery failure. Charging practice should enable batteries to cool before use.

11. As batteries age, their maintenance requirements change, Generally their specific gravity is higher and gassing voltage goes up. This means longer charging time and/or higher finish rate (higher amperage at the end of charge). Usually, older batteries need to be watered more often and their capacity decreases.

12. “Opportunity charging,” a short partial charge during an extended duty cycle, is a controversial subject. If you cannot charge the batteries normally because of extreme operating conditions (24 hour intermittent use, as an example), “opportunity charging” is better than excessive battery discharging. However, the practice can cause batteries to over heat, require more watering, and usually will shorten battery life. “Opportunity charging” is a trade off; something to avoid if possible. One charging cycle per day is preferable.

13. Extreme temperatures can substantially affect battery performance and charging. Cold reduces battery capacity and retards charging. Heat increases water usage and can result in overcharging. Very high temperature can cause “thermal run away” which may lead to an explosion or fire. If extreme temperature is an unavoidable part of an application, consult a battery/charger specialist about ways to deal with the problem.

14. An overly discharged battery might need to be cycled a few times before it can recover fully. If a battery begins to heat before coming up to a full charge, it might be necessary to discharge the battery and recharge it a few times. The charge and discharge cycle might help the current acceptance of the battery and facilitate its recovery to a usable condition.

15. Inactivity can be harmful to deep cycle batteries. If they sit for several months, a “boost” charge should be given - more frequently in warm climate (about once a month) than in cold (every 2-3 months).

16. Never store a battery in a discharged state. The sulfate that forms during discharge can make the battery impossible to recharge fully.

AB46J – 0163187 page 5 - 1

5. Batteries and Battery Charging

■

Battery charging

CAUTION

DO NOT leave the battery charger on for more

than two days. The batteries might be severely overcharged and/or damaged if the charger fails to automatically turn off.

Keep all battery charger ventilation ports open to prevent accumulation of explosive gasses and heat.

Turn the Master Key Switch on the ground control box to OFF and the Battery switch (1) ON.

4. Visually inspect the ammeter (4) for proper charging rate.

●

Initial charge rate will vary from 18 to 22 A depending on how deeply the batteries have been discharged.

●

As the batteries become charged, the ammeter will decrease to5Ato10A depending on the condition of the batteries. Allowing the charger to finish at this low rate is essential to equalize the charge of all battery cells. Leave the battery charger plugged in until it automatically turns itself off.

If the batteries are already fully charged when you connect the charger, the ammeter (4) will initially jump to 15 A to 20 A then quickly decay to zero.

2. Set the Input Voltage switch (2) to 125 or 250 depending on whether you are going to plug the battery charger into a 125 volt AC source of power or a 250 volt AC source of power, respectively.

If the ammeter (4) does not respond, check the source of input power to be sure it is turned on. Reset the 60 A circuit breaker (5) if it has tripped. If the ammeter (4) still does not respond, have a qualified service technician check the input-power fuses (6).

5. After the battery charger has automatically turned itself off, unplug the power cord.

3. Plug the battery charger (3) into a grounded AC outlet (90 - 125/180 - 250 volt AC, 50/60 Hz), using a 3-conductor 12 gauge extension cord that is in good electrical condition. Keep the extension cord as short as possible.

The battery charger will start 3 to 5 seconds after a complete electrical connection is made.

Ground Control Box

Controls for operating the AB46J from the ground, are located on the right side of the turntable.

The number of each control below corresponds to the control’s call out on the control box illustration.

Emergency Stop: Press the red button in, at any time, under any conditions, and the entire machine stops — the drive motors and pump turn off, the brakes automatically set, and nothing moves. This switch must be out for anything on the machine to work.

Platform/Ground Selector : Must be in the GROUND position (down) for the ground control box to work. The switch MUST be in the PLATFORM position (up) for the platform control box to work.

Master Key Switch: This is the master on/off switch. Turn the switch to ON to begin work with the AB46J.

Boom Speed: This control determines how fast the booms move. Set it to SLOW (turtle) until you are very familiar with the way the machine works or if the platform is working in dangerous or cramped surroundings.

Ground Operation: You must manually hold this switch up any time you use one of the seven platform moving switches, (switches 6 through 12), to move the platform. Holding the switch up turns the hydraulic pump on in preparation to do work.

10.

Swing: CW (left) rotates the entire turntable clockwise (as seen from above). CCW (right) rotates the turntable counterclockwise.

11.

Platform Level: UP rotates the platform up relative to the end of the jib boom. DOWN rotates the platform down.

12.

Platform Rotate: CW (left) rotates the platform clockwise (as seen from above) relative to the end of the jib boom. CCW (right) rotates the platform counterclockwise.

13.

Emergency Power: Continuously holding this switch down activates a small, battery powered hydraulic pump that supplies emergency hydraulic power for the machine.

Platform Control Box

Controls for operating the AB46J from the platform are located on the platform control box, with the exception of the foot switch which is on the platform floor.

The number of each control below corresponds to the control’s call-out on the control box illustration.

Emergency Stop: Press the large red button down at any time, under any conditions, and the entire machine stops — the drive motors and pump turn off, the brakes automatically set, and nothing moves. This switch must be pulled to its up (or out) position if the AB46J is to be controlled from the platform.

Drive Range: Switching from LOW to HIGH changes the driving conditions from low speed and high torque to the wheels to high speed and low torque to the wheels. Set this switch to LOW for driving on loading ramps or other steep grades and when safety considerations demand slow deliberate machine movements. Set the switch to HIGH to travel across hard surfaces when the booms are down and retracted.

Platform Rotate: CW (left) rotates the platform clockwise (as seen from above) relative to the end of the jib boom. CCW (right) rotates the platform counterclockwise.

10.

Swing: CW (left) rotates the entire turntable clockwise (as seen from above). CCW (right) rotates the turntable counterclockwise.

11.

Emergency Power: Hold the switch toward you and a small, battery powered hydraulic pump comes on to supply power for the machine. Boom movements will be slow and have long lag times under EMERGENCY POWER. DO NOT use this switch for normal operation.

12.

Horn: The horn is used to get the attention of people on the ground.

13.

Drive/Steer Controller: The Drive/Steer Controller is a joystick type controller to regulate the drive and steer movement as follows:

●

DRIVE FORWARD: Slowly push the Drive/Steer controller FORWARD and the AB46J moves forward. The further forward you push the controller the faster the AB46J goes (max. 3.0 mph, 4.8 km/hr).

●

DRIVE REVERSE: Same as DRIVE FORWARD except the AB46J chassis moves backward

●

STEER RIGHT: Slowly push the Drive/Steer controller to the right and the front wheels move in the direction for a right hand turn. The longer you hold the controller to the right the further the wheels turn.

●

Items 4 through 10 are the platform moving switches. Each is a three position, momentary

contact, normally OFF switch.

(See “Nomenclature and Serial Numbers” in the “Specifications” chapter 3, for boom identification.)

Jib: UP raises the jib boom. DOWN lowers the jib boom.

Extend/Retract: EXTEND extends the inner boom out of the base boom. RETRACT retracts the inner boom into the base boom.

Main Boom Lift: UP raises the base boom. DOWN lowers the base boom.

Riser Lift: UP raises the upper and lower riser booms. DOWN lowers them.

Platform Level: UP rotates the platform up relative to the end of the jib boom. DOWN rotates the platform down.

page 6 - 4 AB46J – 0163187

The wheels stay the direction you turn them, they do not automatically return to center the way automobile wheels do.

There are blue and yellow arrows on top of the chassis. The blue arrows point to the FORWARD end of the chassis and to the LEFT side of the chassis. The yellow arrows point to the REVERSE end of the chassis and to the RIGHT side of the chassis.

The Drive/Steer controller is color coded to match the arrows. The color coding is designed to keep you from becoming disoriented when you are aloft and the platform is rotated with respect to the chassis.

Electronic Display window

■

Electronic Display

The Electronic Display automatically turns on when the AB46J is set for platform control box operation. The Emergency Stop switch (1) MUST be ON (pulled up), to provide power to the Electronic Display to show a message.

The display can show four different types of messages about the status of the drive system and two service status messages:

1. Information messages

2. Wait messages

3. Operator Action messages

4. Service Required messages.

5. Set Up Data.

6. Fault Service Messages Stored In Memory.

To save the batteries, the Electronic Display automatically turns itself off after 15 minutes if the AB46J is not operated. To turn the display back on, step on the foot switch or press the Ground Operation switch.

❑

Information messages

Report normal operating conditions for the AB46J drive system. Anytime the AB46J is operated correctly and is controlled from the

platform-control box an Information message will

appear in the electronic display.

❑

Wait messages

Appear when certain components have overheated. The AB46J cannot be driven while a Wait message is being displayed. When the message goes out the AB46J can be driven, until then the operator should just wait for the component to cool naturally. Boom-moving functions continue to work during these messages.

❑

Operator Action messages

Tell the operator to perform some action that will make the AB46J work correctly. The operator should perform the action then check the display to see that an Information message has returned. An Information message shows the AB46J has returned to a normal operating condition.

❑

Service Required messages

Indicate conditions that are beyond the ability of an operator to correct. The AB46J should be taken out of service immediately and remain out of service until a qualified service technician repairs the problem. The operator should note and report the ERROR (in the second line of the message) to the service technician.

Electronic Display Message Tables

The following tables list the four types of messages that the Electronic Display will indicate and an explanation of each message.

Information message table

❑

Electronic display message:

DRIVE SYSTEM CHECK ***SYSTEM OK!***

CLOSE FOOT SWITCH TO TEST BATTERY

NEUTRAL VEL = 0.0 MPH BATT E F

FORWARD VEL = _._ MPH BATT E F

Explanation of message:

This is the first message to appear after the platform control box is turned on. This message indicates the drive system electrical circuits are operating correctly and will only be displayed a few seconds, then the CLOSE FOOT SWITCH message will appear.

This is the second message to appear during the DRIVE SYSTEM check. It tells the operator that the platform foot switch must be closed (stepped on), to allow the system to check the condition of the battery.

The third message will indicate that in neutral position the drive velocity is 0.0 MPH and will show the state of charge of the batteries. The second line reads like an automobile fuel gauge. If all 10 indicator box's are lit, the batteries are at full (F) charge. If no indicator box's are lit, the batteries are fully discharged. The drive system cannot be operated until this message appears.

After the NEUTRAL message is displayed and you push the Drive/Steer controller to FORWARD, this message appears. It tells you the direction of travel along the ground, the VELOCITY (speed in mph) of travel and the BATTERY condition.

REVERSE VEL = _._ MPH BATT E F

❑

Wait message table

Electronic display message: Explanation of message:

WAIT - CNTRL COOLING MOTOR CNTRL OVERTEMP

After the NEUTRAL message is displayed and you push the Drive/Steer controller to REVERSE, this message appears. It tells you the direction of travel along the ground, the VELOCITY (speed in mph) of travel and the BATTERY condition.

Either WAIT message will automatically clear itself after the component cools to normal operating temperature.

If the component repeatedly overheats, notify a qualified service technician about the problem.

DANGER

Leaking hydraulic oil can cause burns, fires, falls (slipping), cuts, and puncture wounds (if under high pressure). Have a qualified trained maintenance person repair all hydraulic fluid leaks before you operate an AB46J.

Hydraulic oil leaks are easily visible and can show up anyplace. Visually inspect the entire machine for hydraulic oil. Check the ground under the machine for leaked oil. Carefully inspect the ends of the base and inner booms. Oil can run down the inside of the booms and drip out the ends.

Completely lower and completely retract the booms.

The hydraulic oil temperature (1) should be less than 200°F (93°C).

The hydraulic oil level should be between the two marks (2) - (3) on the sight glass gauge.

If necessary, add hydraulic oil at the filler cap (4). See the “specifications” chapter 3, for type and grade of hydraulic oil.

■

Tires

AB46J tires are foam filled. Punctures of the type caused by bolts, screws, or nails are not a problem. Look for large holes or long cuts completely through the tire body: holes or cuts where foam is being forced or eroded out of the tire. Also, look for large imbedded objects, such as angle iron, that can rip a tire body open under some conditions.

AB46J – 0163187 page 7 - 3

■

Operating Procedures

This chapter explains how to properly start and operate an AB46J. Read and understand all the previous chapters in this manual before you begin to operate an AB46J.

CAUTION

If you use the AB46J for painting be sure the optional sandblast protection kit is installed to protect the hydraulic cylinder rods from paint.

■

Control Stations

An AB46J can be operated from the ground control box or from the platform control box. There are basically two differences between ground control and platform control operations, both are safety related:

1. The ground control box can override the platform control box at any time. If a person operating the machine from the platform becomes incapacitated, a person on the ground can always take over machine control.

2. The AB46J can only be driven from the platform control box. The wheels cannot be made to move from the ground control box. This prevents ground control operators from running over themselves.

■

Emergency Stopping

To stop an AB46J, push either the Emergency Stop button at the ground control box or at the

platform control box in.

Ground control box Emergency Stop switch location.

DANGER

The AB46J is not Electrically Insulated.

■

Driving

DANGER

Death or Serious Injury can result from

sudden stops. To avoid sudden stops, do not remove your foot from the platform foot switch while the AB46J is in motion.

The AB46J chassis can only be driven from the platform control box. You cannot drive from the ground control box.

There is a blue arrow on the forward end of the chassis and a yellow arrow on the reverse end of the chassis.

Pushing the Drive/Steer controller to FORWARD causes the chassis to move in the direction of the blue arrow on the end of the chassis.

You must be stepping on the platform foot switch for the Drive/Steer controller to work.

When you release the Drive/Steer controller the wheels stay where you set them. The wheels do not return to the "straight ahead" position the way automobile wheels do.

■

Electrical (GFCI) Outlets at Platform

Pushing the Drive/Steer controller to REVERSE causes the chassis to move in the direction of the yellow arrow on the opposite end of the chassis.

You must be stepping on the platform foot switch for the Drive/Steer controller to work.

■

Steering

The AB46J can only be steered from the platform control box. You cannot steer the AB46J from the ground control box.

There are two blue arrows on the left side of the chassis and two yellow arrows on the right side of the chassis.

Pushing the Drive/Steer controller to LEFT causes the front wheels to turn for a left turn.

Pushing the Drive/Steer controller to RIGHT causes the front wheels to turn for a right turn.

The power input connector (3) for the electrical box (1) is on the top rear of the chassis. Plug a source of power into the power input connector (3) if you intend to use the electrical box (1) to power equipment. Unplug power source before you move the AB46J.

■

Securing for Day

At the end of each work day the AB46J should be returned to the STOWED POSITION and locked as described under “Stowing” in the "Stowing and Transporting" chapter 10.

10. Stowing and Transporting

■

Stowing

At the end of each work day (or in preparation for lifting or storage) a qualified operator should put the AB46J into its STOWED POSITION then lock it.

The correct STOWED POSITION is shown here.

To bring the AB46J into the STOWED POSITION use the controls on the ground control box or platform control box to:

1. Fully retract the booms.

2. Fully lower the booms.

3. Center the base boom between the rear wheels.

■

Transporting

The user assumes all responsibility for choosing the proper method of transportation, and the proper selection and use of transportation and tie-down devices, making sure the equipment used is capable of supporting the weight of the aerial platform and that all manufacturer’s instructions and warnings, regulations and safety rules of their employer, the DOT and/or any other state or federal law are followed.

Trailering

❑

An AB46J weighs approximately 15,900 pounds (7212 kg). Loading ramps and transport trailers must be able to support and safely transport that weight. Forklifts must be able to safely lift that weight.

DANGER

DO NOT load an AB46J on grades over 25%;

or with the turntable rotated with respect to the chassis; or on ramps with poor traction, uneven surfaces, or steps.

Lifting with forklift:

❑

To Lock the AB46J

3. Close and lock all other doors.

A forklift may be used to lift the AB46J onto a transport trailer. Insert the forklift fingers into the forklift tubes on the AB46J shown above.

AB46J – 0163187 page 10 - 1

10. Stowing and Transporting

Driving onto transport trailer

To safely drive an AB46J onto a transport trailer, observe the following steps:

1. Visually inspect the alignment of the loading ramp (1) and the truck or trailer (2). They should both be on the same straight line.

2. Chock (3) the wheels of the truck or trailer so it cannot roll away form the loading ramp (1) while the AB46J is being loaded.

3. Set ground control box for platform operation.

DANGER

Death or Serious Injury can result from

losing control of an AB46J while loading. Always set the Drive Range to LOW before you drive up or down a grade.

Set the Drive Range to LOW.

Use turntable Swing to move the platform slightly to the side so you are aligned with the wheels and can see them better.

10.

Use the Drive/Steer controller to slowly drive the AB46J straight onto the ramp and trailer.

11.

Use turntable Swing to align the base boom between the rear wheels.

12. Lower the jib boom until it is about one foot (0.3 m) above the trailer.

13. Chock the AB46J wheels.

■

Securing to a Transport Vehicle

1. Place two 2” x4” wooded blocks (1) under the rear of the platform (2) as shown. Use Platform Level, on platform control box, to lower the platform (2) onto the blocks (1).

Set the Master Key Switch to OFF then

4. Enter the platform and attach the lanyard of your fall restraint to the lanyard anchor point (4) on the platform.

5. Use the controls on the platform control box (5) to raise jib boom (6) to horizontal position.

6. Use the platform controls to bring the AB46J into the STOWED POSITION, except jib boom horizontal, at foot of the loading ramp (7) with steering wheels (8) nearest ramp (7).

7. Visually check (from the platform) to be sure the AB46J is aligned with the ramp and the ramp is still aligned with the truck or trailer. All should be in a straight line.

page 10 - 2 AB46J – 0163187

remove the key.

Set the Battery switch to OFF and lock the

Battery switch.

CAUTION

DO NOT run a strap over the platform toe

board (3). The toe board is not strong enough to hold the platform down and will be damaged in transit. Run a strap where shown.

4. Run a nylon strap (4) over the platform support (5) to hold the platform on the blocks (1) as shown.

10. Stowing and Transporting

7. Lock the cowling doors closed.

5. Attach chains to the front (6) tie down lugs. Chocks may be removed at this time, though it is a good idea to leave them in place.

6. Attach chains to the rear (7) tie down lugs. Chocks may be removed at this time, though it is a good idea to leave them in place.

DANGER

Transporting a loose AB46J can cause Death or Serious Injury.

8. Use wire-ties, as shown, to keep the platform gravity gate from bouncing around.

9. Use wire-ties, as shown, to keep platform foot switch from bouncing around.

DO NOT attach tie down chains to the steering tie rods. The tie rods are not strong enough to safely hold an AB46J.

AB46J – 0163187 page 10 - 3

Reverse the above procedure after transporting.

10. Stowing and Transporting

■

Towing

The Snorkelift AB46J has not been designed to be towed.

DO NOT tow an AB46J.

DANGER

A runaway AB46J can cause Death or Serious Injury. If you have to move an AB46J

down a grade, chain a braking vehicle to the “up hill “ end of the AB46J.

Be certain the braking vehicle has the capacity to stop and hold both itself and the AB46J on the steepest grade they will encounter and under the prevailing environmental conditions.

In an emergency (if you do not have a forklift large enough to lift an AB46J) when you have to move a disabled AB46J a few feet to safety or for repairs, do the following:

1. Chain a forklift or other heavy vehicle to the front tie down lugs and chain a similar vehicle to the back tie down lugs.

■

Lifting

An AB46J can be safely lifted.

CAUTION

However, to prevent any damage to the AB46J or injury to personnel, only a trained qualified service technician should perform lifting.

2. At each drive wheel, remove the two bolts (1) and turn the disconnect plate (2) over so that the nipple (3) points into the drive motor, then reinstall the bolts (1). (This disengages the brakes and lets the drive wheels free wheel.)

3. Pull the AB46J, at less than 1 mph (1.6 km/hr.), to its new position then turn the disconnect plates back over so the nipples are out and the drive wheels locked.

4. Unchain the AB46J.

page 10 - 4 AB46J – 0163187

■

Air line to platform

The input to the air line is on the lower rear of the turntable. The outlet is on the platform mounting frame. The maximum safe working pressure for the air line is 250 psi (1725 kPa).

CAUTION

Water or antifreeze solution in the air line might damage some air tools. If you use the air line to conduct water or antifreeze solution be sure to drain and blow out the air line before attaching air tools.

The air line can be used to conduct air, water, or antifreeze solution. If you want to conduct other liquids, contact your Snorkel dealer for compatibility information

To drain the air line:

1. Close the turntable end of the air line.

2. Open the platform end of the air line.

3. Raise the base boom slightly above horizontal.

4. Open the turntable end of the air line.

11. Options

If the BumpGard comes into contact with a stationary object, the BumpGard 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 BumpGard infrared switch, in order to move away from the stationary object, do the following:

Hold the Proximity Switch override switch (2) in the up position.

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

3. Return the switch (2) to normal operation once you have moved the platform away from the stationary object.

■

Flashing Lights

■

BumpGard System

The BumpGard system is a spring mounted, padded railing (1) 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 BumpGard and are reflected back to the switches.

The flashing lights alert people that the AB46J is present.

The lights flash at about one flash per second anytime the Battery switch, Master Key Switch, and the Emergency Stop switch, at the ground, are all on.

There is no ON/OFF switch for the flashing lights.

AB46J – 0163187 page 11 - 1

11. Options

■

Motion Warning Alarm

The motion warning alarm emits a very loud sound (...beep...beep...beep...), at ground level, when the Drive/Steer controller is in FORWARD or REVERSE or when one or more booms are in motion.

This alarm alerts people on the ground that the AB46J is moving.

■

Platform Swinging Gate

The optional platform swinging gate is designed to automatically close after you enter or leave the platform.

It helps prevent people from falling off the platform.
