Part Number 0410063EE July, 2005

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, scissors structure, 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, scissors structure, 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 8. 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:

• 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 the platform, or to reach through the scissor arms while operating the aerial platform.

ADanger

Pinch points may exist between moving components. Death or serious injury will result from becoming trapped between components, buildings, structures, or other obstacles. Make sure there is sufficient clearance around the machine before moving the chassis or platform. Allow sufficient room and time to stop movement to avoid contact with structures or other hazards.

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. 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.

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.

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, maximum floor pressure, and drive/lift level sensor interlock information. Raise the platform only when the aerial platform is on level ground.

ADanger

The aerial platform can tip over if it becomes unstable. Death or serious injury will result from a tipover 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 platform in wind speeds above

12.5 m/s (28 mph).

Do not operate the aerial platform within 1.2 m (4′) of any drop-off or hole.

8 S2646/S3246 – 0410063EE

Chapter 3 – Safety

Do not raise the platform in winds above 12.5 m/s (28 mph).

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. Make sure the platform gate and the gravity gate are 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.

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 scissors structure 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.

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. If you are using a fall restraint, transfer your anchorage from one structure to the other before stepping across.

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

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 could 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 will 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.

Placards and Decals

The aerial platform is equipped with placards and decals that provide instruction for operation and accident prevention. Do not operate the aerial platform if any placards or decals are missing or not legible.

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

ADanger

′′

′) of any

′′

Chapter 4 – Safety Devices

This protection system limits the tilt angle if a wheel is driven into a drop-off or hole. This greatly reduces the likelihood of the aerial platform tipping over .

The pothole protection system is for added protection and does not justify operating near drop-offs or holes.

Drive/Lift Pothole Protector Interlock

The aerial platform drive and lift functions are interlocked through a limit switch that senses whether or not the pothole protection linkage is locked into position. The drive/lift pothole interlock operates when the platform is elevated approximately 2.1 to 2.4 m (7 to 8 feet).

If an obstruction under the skids, or some other impairment prevents the skids from locking into position, the drive and lift functions will not operate and an alarm will sound.

Chapter 6 – Batteries

The battery tray contains 4, 240 amp hour , 6 volt batteries. These batteries supply 24 volt DC electrical power to operate the aerial platform drive and platform control systems. Proper machine operation depends on well maintained and charged batteries.

General Maintenance

Always keep the batteries clean, free of dirt and corrosion. A film on top of the battery can accelerate discharge.

Cold reduces battery capacity and retards charging. Heat increases water usage and can result in overcharging. Very high temperatures can cause thermal run away which may lead to an explosion or fire. Consult a battery charger specialist if extreme temperature use is unavoidable.

AWarning

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.

Use distilled water to refill the batteries. A void water containing metallic solids such as iron.

Charging

Fully recharge the batteries, immediately after use. One charging cycle per day is preferred. Fully charged batteries perform best. The deeper the discharge, the fewer number of cycles a battery will deliver. Deep discharges deteriorate the battery quicker than light shallow cycles.

It may take from 1 1/2 to 16 hours to recharge the batteries depending on the amount of discharge. If the charging cycle exceeds 16 hours without the batteries being fully recharged, shut off the charger and have the batteries checked.

Use the following procedure to charge the batteries.

1. Turn the battery disconnect switch off (refer to Figure

6.1). The switch is next to the latch on the battery tray.

An overly discharged battery may need to be cycled a few times before it can fully recover . If a battery begins to heat before becoming fully charged, it may be necessary to recharge and discharge the battery a few times.

The aerial platform is equipped with an automatic battery charger that will completely recharge the batteries and turn off after the charge cycle is completed.

AWarning

Batteries give off hydrogen and oxygen that can combine explosively. Death or serious injury can result from a chemical explosion. Charge the batteries only in a well ventilated area away from sparks or flame.

ACaution

The batteries can be overcharged and/or damaged if the charger fails to shut off automatically. Do not leave the battery charger on for more than two days.

3. Plug the charger into a properly grounded AC outlet using a 3 conductor, 14 gauge or larger extension cord. The extension cord must be as short as possible and in good electrical condition. Make sure the AC voltage selector switch on the charger is set to the same voltage as the outlet voltage. The charger will turn on three to five seconds after a complete electrical connection is made. The ammeter (refer to Figure 6.1) will indicate near 40 amps initially then taper off to 5 to 10 amps as the batteries charge.

Note If the batteries are fully charged when the charger is plugged in, the ammeter will initially read 35 to 40 amps then quickly read zero.

4. Leave the charger plugged in until it shuts itself off.

5. Unplug the extension cord after the battery charger turns itself off. Allow the batteries to cool off after charging.

6. Check the battery water level. Add water to individual cells only if the plates are exposed. Replace the battery caps.

Drive Range Switch

The drive range switch has two positions to select drive wheel operation:

• High (Rabbit) – for normal driving conditions.

• Low (Turtle) – for driving on grades up to 25 percent that require low speed and high torque operation, where high range is not sufficient to climb the grade.

In high the machine will travel up to 3.2 km/h (2 mph) when the platform is raised less than 2.4 m (8′) and up to

0.8 km/h (0.5 mph) when the platform is raised above 2.4 m

(8′). Place the drive range switch in high for normal machine operation.

Place the drive range switch in low, with the plat form fully lowered and the extension deck securely pinned, before driving up a ramp to load the machine for transport.

ACaution

The extension deck is free to move when the pins are disengaged. Make certain the pin is engaged when the deck is extended in the working position and when it is stowed.

ADanger

The aerial platform can tip over if it becomes unstable. Death or serious injury will result from a tipover accident. Do not drive an elevated aerial platform on soft, uneven, or sloping surfaces. Do not drive a fully stowed machine on grades that exceed 25 percent.

A fully stowed machine may be operated on grades up to 25 percent. A grade of 25 percent is a 0.76 m (30″) vertical rise in 3.05 m (10′) horizontal length.

AWarning

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.

Use the following procedure to operate the drive functions.

34 S2646/S3246 – 0410063EE

Drive Speeds

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

Drive speed ranges are interlocked through a limit switch that senses scissors arm position. When the platform is elevated below approximately 2.1 to 2.4 m (7 to 8 feet), the aerial platform may be driven within the full range of drive speeds. Above 2.1 to 2.4 m (7 to 8 feet) of elevation, drive speed is limited to 0.8 km/h (0.5 mph).

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 0.8 km/h (0.5 mph), which is 6.7 m (22′) in 30 seconds, when elevated above 2.4 m (8′).

Chapter 9 – Operation

Drive/Lift Level Sensor Interlock

When the platform is elevated above 2.1 to 2.4 m (7 to 8 feet), lift and drive functions are interlocked through a level sensor system. If the chassis is tilted more than two degrees side-to-side or four degrees front-to-rear, platform raise and drive functions are disabled and an alarm sounds when those controls are activated.

If the drive/lift level sensor interlock shuts off the platform raise and drive functions, lower the platform and drive to a level surface.

Platform raise and drive functions may also be disabled by the pothole protection interlock.

Steering

Overload Protection

When the load in the platform is near or at rated capacity, an alarm will sound and the red light on the upper controls (refer to Figure 9.3) will flash.

Note Holding the steer switch down too long may result in a sharp turn. This is especially true when driving and steering at the same time. It may be easier to turn the wheels in small increments using a series of quick taps on the steer switch.

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

Platform

Use care when entering and exiting the platform to avoid slipping and/or falling. Make certain the entry gate is properly pinned in position. Fully lower the gravity gate when the platform is occupied.

ADanger

The potential for an accident increases when the swing-down rails are lowered. Death or serious injury can result from such accidents. Do not elevate the platform with the swing-down rails lowered.

Be sure the swing-down rails are up and the pins are all installed, anytime the machine is not being transported.

Raising and Lowering

The raise speed is proportional to the joystick position. The farther the joystick is moved, the faster the platform raises. There is only one lowering speed.

Overload Warning Light

Figure 9.3 – Upper Controls

The alarm and light warn the operator that the platform is close to becoming overloaded. All functions remain fully operational.

ADanger

The aerial platform can tip over if it becomes unstable. Death or serious injury will result from a tipover accident. Do not exceed the capacity values indicated on the platform rating placard.

aerial platform – a mobile device that has an adjustable position

platform, supported from ground level by a structure. ambient temperature – the air temperature of the immediate en-

vironment. ammeter – an instrument for measuring the strength of an electric

current in amperes. authorized personnel – personnel approved as assigned to per-

form specific duties at a specific location. base – the relevant contact points of the aerial platform that form

the stability support (e.g. wheels, casters, outriggers, stabilizers). battery tray – a swing-out compartment that holds the batteries

and the battery charger. center of gravity – the point in the aerial platform around which its

weight is evenly balanced. chassis – the integral part of the aerial platform that provides mobil-

ity and support for the scissors structure. fall restraint – a system that is used while working on a boom lift

within the boundaries of platform guardrails to provide restraint from being projected upward from the platform. This system includes a harness or belt, lanyard, and a lanyard anchor. Although federal regulations, OSHA, ANSI, and Snorkel do not require the use of additional fall protection beyond the platform guardrails on scissor lift aerial platforms, local, state, or employer rules may require their use.

floor or ground pressure – the maximum pressure, expressed in pounds per square inch, a single wheel concentrates on the floor or ground.

free-wheeling valve – a needle valve that when adjusted open allows hydraulic fluid to flow through the wheel drive motors. This allows the aerial platform to be pushed or towed without damage to the drive motors.

gradeability – the maximum slope that the aerial platform is capable of travel.

maximum wheel load – the load or weight that can be transmitted through a single wheel to the floor or ground.

Minimum Safe Approach Distance (M.S.A.D) – the minimum safe distance that electrical conductors may be approached when using the aerial platform. Also called M.S.A.D.

operation – the performance of any aerial platform functions within the scope of its specifications and in accordance with the manufacturer’s instructions, the users work rules, and all applicable governmental regulations.

operator – a qualified person who controls the movement of an aerial platform.

personal fall arrest system – a fall protection system that is used while working on an unprotected edge (such as a roof top with no guardrail). This system includes a harness, lanyard or other connecting device, a fall arrestor, an energy absorber or decelerator, an anchorage connector, and a secure anchorage such as a building beam, girders or columns. An aerial platform is not a fall arrest anchorage.

platform – the portion of an aerial platform intended to be occupied by personnel with their tools and materials.

platform height – the vertical distance measured from the floor of the platform to the surface upon which the chassis is being supported.

pothole protection interlock – a safety feature that sounds and alarm and automatically stops the platform raise function if the pothole protection skids are prevented from lowering properly.

pothole protection system – a mechanical tip-over prevention system consisting of skids along the bottom of both sides of the chassis which lower as the platform is raised.

prestart inspection – a required safety inspection routine that is performed daily before operating the aerial platform.

qualified person – a person, who by reason of knowledge, experience, or training is familiar with the operation to be performed and the hazards involved.

guardrail system – a vertical barrier around the platform to prevent personnel from falling.

hazardous location – any location that contains, or has the potential to contain, an explosive or flammable atmosphere as defined by ANSI/NFPA 505.

hydraulic tray – a swing-out compartment that hold the electrical panel for the lower controls, the hydraulic directional control valve, the free-wheeling valve, the pump, and the hydraulic fluid filter.

level sensor – a device that detects a preset degree of variation from perfect level. The level sensor is used to prohibit certain aerial platform functions if operating on a slope greater than the preset value.

lower controls – the controls located at ground level for operating some or all of the functions of the aerial platform. manufacturer – a person or entity who makes, builds, or produces an aerial platform.

maximum travel height – the maximum platform height or the most adverse configuration(s) with respect to stability in which travel is permitted by the manufacturer.
