DANG ER

ELECTRICAL HAZARD

THE TB126J AERIAL WORK PLATFORM IS NOT

ELECTRICALLY INSULATED.

If the platform, booms, or any other conductive part of a TB126J contacts a highvoltage 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 ON THE OPPOSITE PAGE.

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

If a TB126J 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 TB126J. 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 TB126J until you are sure the electricity has been turned off.

If a TB126J is in contact with a live conductor, the platform operator MUST warn others on the ground in the vicinity of the TB126J 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 SERIOUS INJURY or DEATH.

Do not attempt to operate the TB126J ground controls when the platform, booms, or any other conducting part of a TB126J 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 TB126J must be continuously aware of electrical hazards, recognizing that SERIOUS INJURY or DEATH can result if contact with an electrical wire does occur.

T SAFE OPERATION

The following safety information is vitally important for safe operation of the TB126J. Failure to follow these instructions can result in personal injury or DEATH.

Pre-start Inspection

Prior to each shift, the TB126J shall be given a visual inspection and function test. See the “DAILY INSPECTION & MAINTENANCE” chapter in this manual for a list of items to inspect and test.

Do not operate the TB126J unless you are trained and authorized, understand the operation characteristics of the TB126J, and have inspected and tested all functions to be sure they are in proper working order. See the “DAILY INSPECTION & MAINTENANCE” chapter.

Work Place Inspection and Practices

Do not use the TB126J as a ground for welding. Ground to the work piece.

Before the TB126J is used, and during use, check the area in which the TB126J is to be used for possible hazards such as, but not limited to:

•drop-offs or holes

•bumps and floor obstructions

•debris

•overhead obstructions and high voltage

•conductors

•hazardous locations

•inadequate surface and support to withstand

•all load forces imposed by the aerial platform

•in all operating configurations

•wind and weather conditions

•presence of unauthorized persons

•other possible unsafe conditions

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.

1. SAFETY1. SAFETY

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 TB126J to assist the platform operator in the event of an emergency.

When moving the platform, check the clearance around the TB126J 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.

Do not engage in any form of “horseplay” or “stunt driving” while operating the TB126J.

Do not permit riders on the machine anyplace other than on 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.

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

Never steady the platform by positioning it against another platform.

Do not operate a TB126J that is not functioning properly, or has been damaged, until the machine has been repaired by a qualified maintenance person.

Do not operate a TB126J 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.

P/N 0191915

1.SAFETY

Electrocution

The TB126J 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 & Falling Hazards

Do not operate a TB126J 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.

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:

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

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

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

•Use the platform entrance, do not climb over the guard rails.

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

Do not exceed the unrestricted platform capacity shown on the platform.

Do not raise the boom if the TB126J 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.

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.

Raise the platform only when the TB126J is on level ground.

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

Do not use ladders, planks, or other devices to extend or increase your work position from the 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 TB126J as a crane, hoist, or jack.

Do not operate the TB126J in winds, or wind gusts, of 28 mph (45 km/hr) or more.

Do not add anything to the TB126J that will increase the wind loading (billboards, 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.

T 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.

1 - 2	P/N 0191915

Mounting & Dismounting Precautions

Use three points of support when getting on or off the platform (two hands and one foot or a similar set of points). Keep the platform clean.

Do not jump off the machine.

Do not dismount while the machine is in motion.

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 KEY SWITCH, set the BATTERY switch to OFF, then lock the BATTERY switch.

Operating Precautions

Do not modify the TB126J 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 TB126J.

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

Operator Maintenance Precautions

Do not use your hand to search for hydraulic oil leaks. High pressure hydraulic oil can easily cut and penetrate your skin — a very serious 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.

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

Use extreme caution when removing radiator caps. Park the machine and let it cool down before opening a pressurized compartment.

1. SAFETY

Fuel Handling Precautions

Do not smoke or permit open flames while fueling or near fueling operations.

Never remove the fuel cap or refuel a gasoline engine while the engine is running or hot. Never allow fuel to spill on hot machine components.

Maintain control of the fuel filler nozzle when filling the tank.

Do not fill the fuel tank to capacity. Allow room for expansion.

Clean up spilled fuel immediately.

Tighten the fuel tank cap securely. If the fuel cap is lost, replace it with an approved cap from Snorkel. Use of a non-approved cap without proper venting may result in pressurization of the tank.

Never use fuel for cleaning purposes.

For diesel engines, use the correct fuel grade for the operating season.

T SAFETY DECALS & PLACARDS

There are several safety decals and placards on the TB126J. Their locations and descriptions are shown in this section. Take time to study them.

Be sure that all the safety decals and placards on the TB126J 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 CHARTs and DRAWINGs in the “DAILY INSPECTION AND MAINTENANCE” chapter for part numbers, location, and required quantities of all placards and decals.

2. SAFETY2. SAFETYDEVICESDEVICES

For emergency operation controls and procedures, see the “EMERGENCY OPERATION” chapter in this manual.

The devices listed in this chapter are safety devices. They are on a TB126J to increase safety in the work place for both the operator and other people near a TB126J. 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 & MAINTENANCE” chapter). If any is found to be defective, remove the TB126J from service immediately until a qualified service technician can make repairs.

T TILT-ALARM HORN, SIREN, & LIGHT

There is one tilt-alarm siren, one tilt-alarm horn, and one tilt-alarm warning light on a TB126J.

1

The siren (1) is located under the platformcontrol box.

3

2

The horn (2) is located in the turntable under the tilt alarm sensor (3).

The tilt-alarm warning light is on the platformcontrol box.

The siren will emit a two-toned sound (high-low- high-low...) if the TB126J is tilted more than 3.5° (7 inch rise in 10 foot run / 18 cm rise in 3 m run) and the booms are above horizontal or extended more than 7 feet (2 m). The warning light will come on and the horn will emit a continuous sound at the same time the siren sounds.

NOTE: The platform siren will not sound if the TB126J is being controlled from the groundcontrol box.

After the siren and/or horn begins to sound, if the tilt continues to increase, the TB126J can tip over. When you are in control of a TB126J and you hear either of these two warning sounds, or see the warning light come on, you should immediately:

1.Stop using the DRIVE/STEER controller stick on the platform-control box.

2.Completely retract and completely lower the booms.

3.Use the platform-control box DRIVE/STEER controller to move the TB126J to a level surface or more firm ground before extending or raising the booms again.

P/N 0191915

2. SAFETY DEVICES

T EMERGENCY STOP SWITCHES T LANYARD ANCHOR POINTS

At the ground-control box: Press the red

EMERGENCY STOP button in, at any time, under any conditions, and the entire machine stops, the engine turns off, and nothing moves. This switch must be pulled up (out) for anything on the TB126J to work.

OSHA regulations require all personnel on the platform to attach the lanyard of their fall restraint to a secure anchor point to prevent falls. The anchorage point is the anchor to which you should attach your fall restraint lanyard.

T GRAVITY GATE

2

At the platform-control box: Press the large red EMERGENCY STOP button down and the entire machine stops, the engine turns off, and nothing moves. This switch must be pulled to its up (out) position to control the TB126J from the platform.

NOTE: The ground-control box is designed to 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 TB126J.

The gravity gate (1) 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 the anchorage point (2), check to see that the gravity gate (1) has fallen back into place.

2 - 2

P/N 0191915

T FOOT SWITCH

DANG ER

Serious injury can result from sudden stops. To avoid sudden stops, do not remove your foot from the foot switch while the TB126J is in motion.

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

T 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. (It is a second action that must be performed, at the same time as another, to make the platform move.)

2. SAFETY DEVICES

T EXTENDIBLE-AXLE INTERLOCKS

The left and right rear axles of a TB126J must be extended and locked for safe-working machine stability. The booms cannot be raised or extended unless the axles are completely extended and locked into place. Instructions for extending and locking the axles are given in the “OPERATION” chapter.

T EMS LIGHTS & AUDIO ALARMS

There are six envelope management system (EMS) lights on a TB126J.

Three are on the instrument panel.

P/N 0191915

2 - 3

2. SAFETY DEVICES

A second identical set of three is on the platformcontrol box.

2

1

3

The EMS ENVELOPE lights (1) give the operator information about where the platform is located relative to the platform’s safe working envelope. (See the “SPECIFICATIONS” chapter for the TB126J safe working envelope.) The EMS STATUS (2) and EMS WARNING lights (3) tell the operator whether or not the envelope management system is operating correctly .

NOTE: EMS lights on the platform-control box have the same names as those on the instrument panel even though they are not labeled on the platform-control box.

In addition to EMS lights there are EMS audio alarms.

Two are above the instrument panel.

Two are on the bottom of the platform-control box. The audio alarms emit various sounds to alert the operator to unsafe conditions. The audio alarms and EMS lights work together to give valuable safety information. The table below summarizes that information.

NOTE: When a TB126J engine first starts, the EMS self-test will briefly sound all EMS audio alarms and briefly turn all six EMS lights on to check that they work. After the brief EMS selftest, conditions in the table below prevail.

Two 30 watt headlights are located on top of the front cowling, two 25 watt blinking taillights are on the sides of the rear cowlings. Driving lights help improve your visibility and help others see you when you are driving on dimly lit construction sites. Driving lights are not for driving on public thoroughfares.

For more information about driving lights see the “OPTIONS” chapter.

T FLASHING LIGHTS (option)

The flashing lights alert people that the TB126J is present. The lights flash at about one flash per second any time the engine is running. There is no ON/OFF switch for the flashing lights.

T PLATFORM WORK LIGHTS (option)

The platform work lights are located on top the platform guard rail. Use the lights to improve visibility when you are working aloft in dimly lit areas. Do not use the platform work lights to drive on public thoroughfares.

For more information about platform work lights see the “OPTIONS” chapter.

T MOTION WARNING ALARM (option)

The motion warning alarm emits a loud beeping sound at ground level anytime the DRIVE/STEER controller is in FORWARD or REVERSE. This alarm alerts people on the ground that the TB126J is traveling along the ground.

T GFCI OUTLET (option)

The GFCI (ground fault circuit interrupt) is the electrical outlet located under the platformcontrol box. The GFCI protects against short circuits to ground. When there is a short to ground the GFCI shuts off power at the electrical outlet.

For more information about the GFCI see the “OPTIONS” chapter.

T GUARDRAILS

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

	1	T AMPS

The air filter gauge (1) (FILTER MINDER) is located just above the ground-control box. The gauge measures the vacuum (air pressure) between the intake manifold and the air filter. As the filter clogs, the vacuum increases (pressure drops). As the vacuum increases, the yellow indicator (2) raises toward the red area (3) of the sight glass. When the yellow indicator reaches the red, it’s time to change the air filter.

The indicator (2) stays at its highest setting, it does not go to the bottom of the sight glass when the engine is turned off. After the filter is changed, press the small RESET button (4) to reset the indicator disk to the bottom of the sight glass.

T TEMPERATURE

The TEMPERATURE gauge is located just above the ground-control box. It shows the

The AMPS gauge shows the electric current from the alternator to the batteries. When the engine is running, the needle in the AMPS gauge should not be to the left of “0.” Under normal operating conditions, after the engine has been running for a few minutes, this gauge should read “0.”

The HOURS gauge is basically an electric clock. It accumulates time when:

The fuel gauge (1) is located on top of the gasoline or diesel fuel tank (2). Read it at the line

(3) in the clear plastic window (4). It reads in fractions-of-a-full-tank. The tank shown is a little more than 1/4 full.

NOTE: Do not run a diesel fuel tank dry. Air in the fuel line makes a diesel engine hard to start.

The hydraulic-oil level gauge (1) is on the side of the hydraulic oil tank (2). It shows the actual level of oil inside the tank. Read it only when the booms are completely down and completely retracted. Otherwise, the lift and/or extend 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).

T HYDRAULIC OIL TEMPERATURE

(OPTION - LPG) LPG tanks have two fuel gauges (1) (2) on top. One measures correctly when the tank is standing on end (VERTICAL) the other measures correctly when the tank is laying down (HORIZONTAL). Both read in fractions-of- a-full-tank. TB126J tanks are mounted horizontally. Therefore, you should read the HORIZONTAL scale (2).

The hydraulic-oil temperature gauge (1) is located at the bottom of the hydraulic-oil level gauge. It measures the temperature of the oil in the tank (2). The temperature should not exceed 200°F (93°C). If it does, reduce your driving speed or stop the TB126J to let the hydraulic oil cool.

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.

The hydraulic-oil filter gauge should only be read by qualified trained maintenance personnel. An accurate reading requires very special conditions and should not be attempted by operators.

Engine oil level is measured with a dipstick (1)

(2). Oil sump and oil filter capacities given in the “SPECIFICATIONS” chapter are approximate. True values may vary from machine to machine due to slight variations or modifications during production. The oil dipstick is the only way to accurately gauge if the engine oil level is correct.

Engine oil level should always be in the crosshatched area (3) (4) of the dipstick — never above or below it. Check the oil level after the engine has been turned off a few minutes so that oil can run down out of the engine into the sump.
