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 dened 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.

Chapter 3 – Safety

D e n o tes prohib ite d zone

Knowledge of the information in this manual, and proper training, provide a basis for safely operating the aerial platform. Know the location of all controls and how they operate to act quickly and responsibly in an emergency.

Safety devices reduce the likelihood of an accident. Never disable, modify, or ignore any safety device. Safety alerts in this manual indicate situations where accidents may occur.

If any malfunction, hazard or potentially unsafe condition relating to capacity, intended use, or safe operation is suspected, stop aerial platform operation and seek assistance.

The operator bears ultimate responsibility for following all manufacturer’s instructions and warnings, regulations and safety rules of their employer and/or any state or federal law.

Electrocution Hazards

The aerial platform is made of metal components and is not insulated. Regard all conductors as energized. Do not operate outside during a thunderstorm.

Minimum Safe Approach Distance

Minimum safe approach distances to energized power lines and their associated parts must be observed while operating the aerial platform.

Danger

The aerial platform is not electrically insulated. Death or serious injury can result from contact with, or inadequate clearance from, an energized conductor. Do not go closer than the minimum safe

approach distance as dened by ANSI.

ANSI publications dene minimum distances that must

be observed when working near bus bars and energized power lines. Table 1 and Figure 3 are reprinted courtesy of Scaffold Industry Association, ANSI/SIA A92.5.

Chapter 3 – Safety

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. Elec-

trical current ow 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 oor 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

congurations

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.

Do not operate the aerial platform if it is damaged or not

functioning properly. Qualied 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 oor grating or otherwise obstruct your view below. Make sure the area below the platform is free of personnel before lowering.

Before using the aerial platform in any hazardous (clas-

sied) location, make certain it is approved and of the

type required for use in that particular location.

Know and understand the job site trafc-ow patterns and obey the agmen, road signs and signals.

While operating the aerial platform, a good safety

practice is to have qualied personnel in the immediate

work area to:

• 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

Danger

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 sufcient clearance around the machine before moving the chassis, booms, or platform. Allow sufcient room and time to stop movement to avoid contact

with structures or other hazards.

Warning

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.

Keep both feet positioned rmly on the platform oor.

Operate the controls slowly and deliberately to avoid jerky and erratic operation. Always stop the controls in neutral before going in the opposite direction.

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 rm, at, level

surface capable of withstanding all load forces imposed by the aerial platform in all operating conditions. Refer to

the General Specications chart for the maximum wheel

load and ground pressure. Raise the booms only when the aerial platform is on level ground.

14 T125J/TB125J – 0192214

Chapter 3 – Safety

Danger

The aerial platform can tip over if it becomes unstable. Death or serious injury can result from a tip-over accident. 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. Do not raise the boom in winds above 28 mph (45 km/h).

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.

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.

Electrical System

Charge the batteries in a well-ventilated area free of

ame, sparks, or other hazards that might cause re

or explosion.

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

Warning

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 ames 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.

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, ags, 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, trail-

ers, railway cars, oating 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.

Chapter 3 – Safety

Danger

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.

Be careful not to run the diesel fuel tank empty. Bleed the fuel system if air enters the lines between the tank and the injection pump.

Allow the engine to return to idle before shutting the engine off.

Do not smoke or permit open ames while fueling or

near fueling operations.

Never remove the fuel cap or ll the fuel tank while the

engine is running or hot. Never allow fuel to spill on hot machine components.

Maintain control of the fuel ller nozzle when lling the tank. Spilled fuel is a potential re hazard.

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.

Figure 7.6 – Batteries

Warning

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 ames or sparks when checking the batteries.

Chapter 7 – Prestart Inspection

Cables and Wiring Harness

Inspect all cables and wiring for wear and/or physical damage such as loose connections, broken wires and frayed insulation. Check the wiring in areas where a change in routing direction may cause them to become pinched (refer to Figure 7.7). Make sure the cables and wires are properly routed to avoid sharp edges, pinching

and scufng.

Caution

Even with low voltage electrical systems, severe

arcing can occur. Electrical shock or component damage can result from contact with energized conductors. Use caution when working with any

electrical device.

The batteries are automatically charges when the engine is running. Include the batteries when inspecting and

servicing the electrical system.

Battery Fluid Level

Remove the caps from each battery. Visually check the battery uid level. If the level is not within 6 mm (1/4″)

of the bottom of the ller neck inside each hole, add

distilled water.

Replace the caps on the batteries. The caps must be in place and tight during machine operation.

Battery Terminals

Check the top of the batteries, the terminals and cable ends. They should be clean and free of corrosion. Clean the top of the batteries if necessary. Clean the terminals and cable ends with a wire brush or terminal cleaning tool. All cable ends must be securely fastened to the terminals.

Figure 7.7 – Cables and Wiring Harness

Hydraulic System

Hydraulic power is supplied from an engine driven variable displacement piston pump.

Danger

Hydraulic uid escaping under pressure can have enough force to inject uid into the esh. Serious

infection or reaction can result if medical treatment

is not given immediately. In case of injury by escaping hydraulic uid, seek medical attention at once.

The hydraulic reservoir is behind the door on the right side of the turntable. The pump is mounted on the engine.

Fluid Level

Check the hydraulic reservoir uid level with the aerial platform stowed on a level surface. The uid level must be between the full and add marks as viewed on the sight glass (refer to Figure 7.8).

Figure 7.8 – Fluid Level Indicator

Caution

Not all hydraulic uid is suitable to use in the hydraulic system. Some have poor lubricating char-

acteristics and can increase component wear. Only

use hydraulic uid as recommended.

If necessary, remove the ller cap and add uid of the proper type. Refer to Chapter 2 for the proper type and

grade of hydraulic uid to use. The need to regularly add uid indicates a leak that should be corrected.

The sight glass on the reservoir has an internal thermom-

eter to measure the uid temperature. The temperature

should be less than 200°F (93°C).

Fluid Filter

Checking the condition of the hydraulic uid lter is part

of the machine maintenance schedule and should not be performed by the operator.

Hoses, Tubes, and Fittings

Chapter 8 – Operation

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

Danger

The aerial platform is not electrically insulated. Death or serious injury can result from contact with, or inadequate clearance from, an energized conductor. Do not go closer than the minimum safe

approach distance as dened by ANSI.

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 sufcient clearance around the machine before moving the chassis, booms, or platform. Allow sufcient 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 can result from a tipover accident. Operate the aerial platform on a rm, at, level surface. Avoid travel speeds and/or rough

terrain that could cause sudden changes in platform

position. Do not drive or position the aerial platform for elevated use near any drop-off, hole, slope, soft or uneven ground, or other tip-over hazard.

The platform rated work load is the total weight of the personnel and equipment that may be lifted in the platform. The work loads are stated on the platform rating placard mounted at the rear of the platform.

Engine Cold Weather Start Kit

The optional engine cold weather start is be an engine block heater.

The last two letters of the model number stamped on the serial number placard indicates the engine manufacturer (refer to Figure 8.1). The serial number placard is mounted on the front of the turntable.

Danger

The aerial platform can tip over if it becomes unstable. Death or serious injury can result from a tip-over accident. Do not exceed the capacity values

indicated on the platform rating placard.

Capacity values indicate the rated lifting capacity and do not indicate aerial platform stability.

The operator bears ultimate responsibility for ensuring that the aerial platform is properly set up for the particular conditions encountered.

Cold Weather Start-Up

If the ambient temperature is 32°F (0°C) or below, the engine and hydraulic system oil may need to be warmed before operation. Do not operate the engine at more than a fast idle until the engine and hydraulic oil has had a chance to warm. The engine may be equipped with an optional cold weather start kit.

Cold, thick hydraulic oil does not ow well and may

cause delay in response to control movement and improper voltage output of the 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.

Unplug the power cord before starting the engine.

Hydraulic System Cold Weather Warm-Up

Some engines may have a hydraulic uid warm-up system that will automatically warm the uid upon activating the warm-up switch. The hydraulic uid may also be

warmed manually if the machine is not equipped with the optional warm-up system.

Caution

Not all hydraulic uid is suitable to use in the hydraulic system. Some have poor lubricating char-

acteristics and can increase component wear. Only

use hydraulic uid as recommended.

Use cold weather hydraulic oil as recommended in the

machine General Specications in temperatures of 10°F

(-13°C) or below.

Hydraulic System Warm-Up Switch

This system may be used to warm the hydraulic uid

when the ambient temperature is below 32°F (0°C) and

boom movement is sluggish because of cold uid.

There is a toggle switch for the warm-up system on the lower control panel and one on the left side of the upper control panel.

T125J/TB125J – 0192214 47

Chapter 8 – Operation

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.

Machine functions are not operational while using the hydraulic warm-up system.

To operate the warm-up system:

1. Place the engine throttle in the slow position.

2. Place the controls selector switch in the lower control position.

3. Place the warm-up switch in the on position.

4. After the hydraulic uid 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 toggling the Boom/ Axle switch to Axle. The boom must be in the stowed position.

Caution

Not all hydraulic uid is suitable to use in the hydraulic system. Some have poor lubricating char-

acteristics and can increase component wear. Only

use hydraulic uid as recommended.

Use cold weather hydraulic oil as recommended in the

machine General Specications in temperatures of 10°F

(-13°C) or below.

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.

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. Boom elevation and extension is limited when the rear axles are retracted. The lower controls may be used for initial set up of the aerial platform, and for testing and inspection.

Chapter 8 – Operation

Driving and Steering

Danger

The aerial platform can tip over if it becomes unstable. Death or serious injury can result from a tip-over accident. Do not drive an elevated aerial platform on soft, uneven, or sloping surfaces. Do not drive four wheel drive machines on grades that

exceed 30 percent.

For operation of four wheel drive machines on grades up to 30 percent, it is recommended that the main boom be near horizontal and the jib 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.

Avoid driving with the platform over the front (steer) end

of the chassis. In this position the machine is difcult to

control because:

drive and steer control movements and their result-



ing 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.

Use the following procedure to operate the drive and steer functions.

1. Determine the desired drive range for the specic

driving conditions.

Use high range when traveling across rm, at,



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

Use low range for driving on loading ramps or



other steep grades and when safety considerations demand slow deliberate machine movement. Low range is for low speed, high torque operation.

2. Step down on the platform foot switch.

3. Push the drive joystick forward to move the chassis forward, the direction of the blue arrow. Pull the joystick backward to move the chassis backward, the direction of the yellow arrow. The drive speed is proportional to the joystick position.

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

5. Push the drive joystick to the right to steer to the right, the direction of the yellow arrow. Push the joystick to the left to steer to the left, the direction of the blue arrow.

Warning

Death or serious injury can result from improperly

driving or steering the aerial platform. Read and

understand the information in this manual and on

the placards and decals on the machine before operating the aerial platform on the job.

The blue and yellow arrows on the chassis indicate the direction the chassis will move when the drive or steer control is moved toward the corresponding color.

When the machine is in the stowed position, with the booms centered between the rear wheels, the direction of drive and steer control movement corresponds with the direction of chassis movement.

When the turntable is rotated from the stowed position, with the booms to either side of or in front of the chassis, the direction of control movement does not correspond with the direction of chassis movement.

To avoid confusion, always drive to the work area or move between work areas with the turntable and booms in the stowed position. After arriving at the work area, the booms may be positioned to the side or the front

of the chassis for nal positioning. Always look in the

direction of movement as indicated by the directional arrows on the chassis.

Note The steering wheels are not self-centering. The machine must be driving to steer the wheels and must be driving fast enough to release the brakes for steering to work. Set the steering wheels straight ahead after completing a turn.

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

Drive Speeds

The drive speed is proportional to the joystick position. The farther the joystick is moved, the faster the travel speed.

Always slow down and shift the drive system to low range before traveling over rough terrain or any sloped surface.

Drive speed ranges are interlocked through a limit switch that senses the main boom position. When the boom is elevated up to midway, only the low drive speed will work. When the boom is elevated to midway or above, only the creep drive speed will work.

T125J/TB125J – 0192214 51

Chapter 8 – Operation

Warning

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 0.75 mph (1.2 km/h) [33′ (10 m) in 30 seconds] when the booms are elevated from the stowed position.

Motion Warning Alarm

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

Four Wheel Drive

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

High Range Speed Selector

The high range speed selector (refer to Figure 8.8), on four-wheel drive machines, works in conjunction with the drive range switch to determine the maximum drive speed when the drive range selector is in the HI position. LO drive range speed is not affected by the high range speed selector.

Caution

Cold hydraulic oil does not ow well and may produce improper generator output voltage. Improper outlet voltage can damage some electrical power tools and equipment. Warm the hydraulic oil before

operating the generator.

Do not operate the generator unless the hydraulic oil temperature is at least 100°F (38°C). Refer to Cold Weather Start-Up for a hydraulic oil warm-up procedure.

Start the engine and place the machine/generator switch (refer to Figure 8.9) in the generator position.

1. Close the input connector on the chassis.

2. Open the output connector at the platform.

3. Raise the boom slightly above horizontal.

4. Open the input connector on the chassis.

5. Allow the uid 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. There are two headlights at the front of the chassis and two blinking taillights at the rear of the chassis.

The lights are operational when the battery disconnect switch and the master switch 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. The direction a light points can be adjusted by using two 1/2″ wrenches to loosen the clamp below the light.

The lights are operational when the upper controls emergency stop button is pulled up and the anti-restart master switch is turned on.

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