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.

Prestart Inspection

Perform a prestart inspection before each shift as described in Chapter 7. Do not use the aerial platform on the job unless you are trained and authorized to do so.

Work Place Inspection and Practices

Do not use the aerial platform as a ground connection when welding. The welding ground clamp must be attached to the same structure that is being welded. Electrical current flow can be very intense, causing serious internal damage to some components.

Inspect the area before and during aerial platform use. The following are some potential hazards that may be in the work place.

• Debris

• Slopes

• Drop-offs or holes

• Bumps and floor obstructions

• Overhead obstructions

• Unauthorized persons

• High voltage conductors

• Wind and weather conditions

• Inadequate surface and support to withstand load forces applied by the aerial platform in all operating configurations

Before using the aerial platform in any hazardous (classified) location, make certain it is approved and of the type required by ANSI/NFPA 505 for use in that particular location.

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

While operating the aerial platform, a good safety practice is to have qualified personnel in the immediate work area to:

Always look in the direction of movement. Drive with care and at speeds compatible with the work place conditions. Use caution when driving over rough ground, on slopes, and when turning. Do not engage in any form of horseplay or permit riders any place other than in the platform.

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 objects that do not belong in or on the aerial platform.

Never steady the platform by positioning it against another platform.

AWarning

The potential for an accident increases when operating an aerial platform that is damaged or malfunctioning. Death or serious injury can result from such accidents. Do not operate the aerial platform if it is damaged or malfunctioning.

Do not operate the aerial platform if it is damaged or not functioning properly. Qualified maintenance personnel must correct the problem before putting the aerial platform back into service.

Operation

Use three points of support when entering or exiting the platform. For example, use two hands and one foot when climbing into the platform.

Never cover the platform floor grating or otherwise obstruct your view below. Make sure the area below the platform is free of personnel before lowering.

Keep both feet positioned firmly on the platform floor. Operate the controls slowly and deliberately to avoid jerky and erratic operation. Always stop the controls in neutral before going in the opposite direction.

• Help in case of an emergency

• Operate emergency controls as required

• Watch for loss of control by platform operator

• Warn the operator of any obstructions or hazards that may not be obvious to them

• Watch for soft terrain, sloping surfaces, drop-offs, etc. where stability could be jeopardized

• Watch for bystanders and never allow anyone to be under, or to reach through the booms while operating the aerial platform

ADanger

Pinch points may exist between moving components. Death or serious injury can 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.

12 TB80/TB85J Fixed Axle – 0112792

Do not dismount while the aerial platform is in motion or jump off the platform.

Properly stow the aerial platform and secure it against unauthorized operation at the end of each work day, before transporting, or if it is left unattended.

Tip-Over and Falling Hazards

Operate the aerial platform only on a firm, flat, level surface capable of withstanding all load forces imposed by the aerial platform in all operating conditions. Refer to the General Specifications chart for the maximum wheel load and ground pressure. Raise the booms only when the aerial platform is on level ground.

ADanger

The aerial platform can tip over if it becomes unstable. Death or serious injury can result from a tipover accident. Do not drive or position the aerial

Chapter 3 – Safety

platform for elevated use near any drop-off, hole, slope, soft or uneven ground, or other tip-over hazard.

All platform occupants must wear a fall restraint device connected to a lanyard anchor point.

It is best not to transfer from the platform to another structure or from the structure to the platform, unless that is the safest way to do the job. Judge each situation separately taking the work environment into account. If it is necessary to transfer from the platform to another structure the following guidelines apply:

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

2. Transfer your anchorage from one structure to the other before stepping across.

3. Remember that you might be transferring to a structure where personal fall arrest is required.

4. Use the platform entrance, do not climb over or through the guardrails.

Do not operate the aerial platform in windy or gusty conditions. Do not add anything to the aerial platform that will increase the wind loading such as billboards, banners, flags, etc.

Never operate the aerial platform without all parts of the guardrail system in place and the gate closed. Make sure that all protective guards, cowlings, and doors are securely fastened.

Do not exceed the platform capacity as indicated on the platform rating placard on the platform. Do not carry loads that extend beyond the platform guardrails without prior written consent from Snorkel.

Do not operate the aerial platform from trucks, trailers, railway cars, floating vessels, scaffolds, or similar equipment unless the application is approved in writing by Snorkel.

Do not use the aerial platform as a crane, hoist, jack, or for any purpose other than to position personnel, tools, and materials.

Electrical System

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

Do not operate any of the aerial platform functions while the battery charger is plugged in.

AWarning

Batteries give off hydrogen and oxygen that can combine explosively. Death or serious injury can result from a chemical explosion. Do not smoke or permit open flames or sparks when checking the batteries.

Battery acid can damage the skin and eyes. Serious infection or reaction can result if medical treatment is not given immediately. Wear face and eye protection when working near the batteries.

Batteries contain sulfuric acid that can damage your eyes or skin on contact. Wear a face shield, rubber gloves, and protective clothing when working around batteries. 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.

Hydraulic System

The hydraulic system contains hoses with hydraulic fluid under pressure.

ADanger

Hydraulic fluid escaping under pressure can have enough force to inject fluid into the flesh. Serious infection or reaction can result if medical treatment is not given immediately. In case of injury by escaping hydraulic fluid, seek medical attention at once.

Do not place your hand or any part of your body in front of escaping hydraulic fluid. Use a piece of cardboard or wood to search for hydraulic leaks.

Engine and Fuel Handling Precautions

Refer to the engine manufacturer’s Operator’s Manual for complete information on safe engine operation, maintenance, and specifications.

Do not climb on the guardrails or use ladders, planks, or other devices to extend or increase the work position from the platform.

Take care to prevent rope, electrical cords, and hoses, etc., from becoming caught in or on the aerial platform. If the platform or booms becomes caught on an adjacent structure or other obstacle and is prevented from normal motion, reverse the control to free the platform. If control reversal does not free the platform, evacuate the platform before attempting to free it.

TB80/TB85J Fixed Axle – 0112792 13

Engine exhaust contains carbon monoxide, a poisonous gas that is invisible and odorless. Breathing engine exhaust fumes can cause death or serious illness. Do not run the engine in an enclosed area or indoors without adequate ventilation.

Operate dual fuel machines on LPG fuel when indoors to reduce exhaust fumes and carbon monoxide.

ADanger

Chapter 8 – Operation

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.

ACaution

Not all hydraulic fluid is suitable to use in the hydraulic system. Some have poor lubricating characteristics 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 (0°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 left side 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.

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.

Preparing for Operation

Use the following procedure to prepare the aerial platform for operation.

1. Perform a prestart inspection as described in Chapter 7.

2. Place the battery disconnect switch in the on position.

3. Close and latch the doors.

4. Before painting or sandblasting make sure the sandblast protection kit and the platform control cover are properly installed. These options, when used properly will protect the control placards and cylinder rods from paint overspray and abrasion while sandblasting.

Lower Controls

The lower controls override the upper controls. This means that the lower controls can always be used to operate the platform regardless of the position of the upper control emergency stop button.

Boom, turntable, and platform functions may be operated from the lower controls. The lower controls may be used for initial set up of the aerial platform, and for testing and inspection.

Use the following procedure to operate boom, turntable, or platform functions using the lower controls.

1. On dual fuel machines, set the fuel switch to either LPG or gasoline.

2. Open the shut-off valve on the tank if using LPG.

3. Place the emergency stop switch (refer to Figure 8.2) in the on position and place the controls switch in the ground position.

3. After the hydraulic fluid reaches 50°F (10°C) as indicated 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.

ACaution

Not all hydraulic fluid is suitable to use in the hydraulic system. Some have poor lubricating characteristics 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 (0°C) or below.

2. Hold the appropriate control in the desired direction. Always look in the direction of movement.

3. Releasing the control to its neutral position, or releasing the foot switch will stop movement.

Driving and Steering

ADanger

The aerial platform can tip over if it becomes unstable. Death or serious injury can result from a tipover accident. Do not drive an elevated aerial platform on soft, uneven, or sloping surfaces. Do not drive the machine on grades that exceed 30 percent.

For operation on grades up to 30 percent, it is recommended that the main boom be near horizontal and the jib on TB85J machines elevated just enough to provide adequate ground clearance.

A 30 percent grade is a 36″ (0.91 m) vertical rise in 10′ (3.05 m) horizontal length.

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 (two wheel drive) 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.

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.

46 TB80/TB85J Fixed Axle – 0112792

• Use mid range (four wheel drive) when traveling across soft surfaces or those with small inclines. Mid range can only be activated when the booms are stowed. Mid range is for medium speed, high torque operation.

• Use low range (four wheel drive) 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. Determine the desired steer mode for the specific driving conditions. Place the switch in the four wheel coordinated, two wheel, or crab steer mode position to achieve the desired machine movement. Refer to Figure 8.5

Page 51

Chapter 8 – Operation

Steer Modes

Four Wheel Coordinated

• Front wheels turn in steer direction

• Rear wheels turn in the opposite direction

Two Wheel

• Front wheels turn in steer direction

• Rear wheels do not turn

Crab

• Front and rear wheels turn in steer direction

Figure 8.5 – Steer Modes

• Use two wheel steer for most machine operation such as travel between jobs and to position the machine near the job location.

• Use four wheel coordinated steer when a tight turning radius is desired for positioning the machine.

• Use crab steer to travel in a diagonal motion in the direction of the wheels.

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 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.

AWarning

The potential for an accident increases when safety devices do not function properly. Death or serious injury can result from such accidents. Do not alter, disable, or override any safety device.

Do not use the aerial platform if it drives faster than 0.6 miles per hour (26 feet in 30 seconds) when the booms are elevated from the stowed position.

Motion Warning Alarm

The motion warning alarm sounds loud intermittent beeps when the drive joystick is in the forward or reverse position.

Note The steering wheels are not self-centering. Set the steering wheels straight ahead after completing a turn and before switching from one steer mode to another.

3. Step down on the platform foot switch.

4. 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.

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

6. 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. The wheels will steer only when the drive joystick is in the forward or reverse drive position, or when the booms are stowed.

Note The steering wheels are not self-centering. Set the steering wheels straight ahead after completing a turn.

7. After driving to the desired location, release the foot switch, or push the emergency stop button to apply the parking brakes.

Electrical Power Outlet

The electrical outlet at the platform has 2, 3-prong, 125 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 on the left side of the wiring box (refer to Figure 8.6). Unplug the source of power before moving the aerial platform.
