Electrical Hazard Warning

THE SNORKELIFT AERIAL WORK PLATFORM

IS NOT ELECTRICALLY INSULATED.

Electrical Hazard

DANGER

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

GO NO CLOSER THAN THE MINIMUM SAFE APPROACH DISTANCES

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

ON THE NEXT PAGE.

Be sure to allow for sag and sway in the wires and the work platform. If a Snorkelift comes in contact with a live electrical conductor, the entire machine can be charged. If that happens, you should remain on the machine and not contact any other structure or object within

reach. That includes the ground, adjacent buildings, poles, and any object not a part of the Snorkelift. Suchcontact could makeyourbody aconductor to theother objectcreating an electricalshock hazardre-

sulting in SERIOUS INJURY or DEATH. DO NOT attempt to enter or leave the Snorkelift until you are sure the electricity has been turned off. If aSnor kelift is in contactwith a liveconductor, the platform operator MUST warn others on the ground in

the vicinity of the Snorkelift to STAY AWAY from the machine, since their bodies can also form a path for electricity to ground thus creating an electrical shock hazard with possible ELECTROCUTION and DEATH.

DONOTattempttooperatetheSnorkeliftground controls whentheplatform,booms,oranyother conduct ingpartofa Snorkeliftisincontact with electricalwiresorifthereisanimmediatedangerofsuchcontact.

Regard all conductors as energized. Personnel working on or near a Snorkelift must be continuously aware of electrical hazards, recognizing

that SERIOUS INJURY or DEATH can result if contact with an electrical wire does occur.

Pre-start Inspection

❑

Atthe start ofeachwork shift,the MHP12/34Jshall be given a visual inspection and function test. See the “Daily Inspection and Maintenance” chapter 7, inthismanualfora list ofitems to inspectand test.

1. Safety

When moving the platform, check the clearance around theMHP12/34J to avoidcontact with struc tures or other hazards.Alwayslook in the direction

of motion.

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

Secureallaccessories,containers,tools,and other materials inthe platformto preventthem from acci dentally falling or being kicked off the platform.

DONOTengage inanyformof“horseplay”or“stunt driving” while operating the MHP12/34J.

CAUTION

DO NOT operate the MHP12/34J unless you are trained and authorized, understand the operation characteristics of the MHP12/34J, and have inspected and tested all functions to be sure they are in proper working order.

Work Place Inspection and Practices

❑

Donotuse theMHP12/34Jas a groundforwelding. Ground to the work piece.

Before the MHP12/34J is used, and during use, check the area in which the MHP12/34J is to be used for possible hazards such as, but not limited to:

1. Drop-offs or holes.

2. Side slopes.

3. Bumps and floor obstructions.

4. Debris.

5. Overhead obstructions and electrical conductors.

6. Hazardous locations.

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

8. Wind and weather conditions.

9. Presence of unauthorized persons.

10. Other possible unsafe conditions. Before the MHP12/34J is used, determine the haz

ardclassification of anyparticular atmosphere or lo cation according to ANSI/NFPA 505-1987.

Any MHP12/34J operated in a hazardous location must be approved and of the type required by ANSI/NFPA 505-1987.

A recommended safety practice is to have personnel that are trained in the operation of the emergency controls working in theimmediate area ofthe MHP12/34J to assist theplatform operatorin the event of an emergency.

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

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

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

Never steady the platform by positioning it against another platform.

DO NOT operate an MHP12/34J that is not functioning properly, or has been damaged, until the machine has been repaired by a qualified maintenance person.

DO NOToperate a MHP12/34J that does not have all its decals and placards attached and legible.

Watchforbystandersand neverallow anyonetobe under, or to reach through, the machine and its equipment while operating.

Use the recommended transport device when loading the machine.

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

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

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

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

DO NOT climb the rails. Use the entrance.

All platform occupants MUST wear and use fallre straint.Attach fall restraints to the platform lanyard anchor points.

DO NOT exceedthe unrestricted platformcapacity asindicatedonthecapacity placard attheentrance to the platform.

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.

Fuel Handling Precautions

❑

DONOTsmokeor permitopenflames while fueling or near fueling operations.

Neverremove the fuel cap or refuel a gasoline engine while the engine isrunning or hot.Neverallow fuel to spill on hot machine components.

part. See your Snorkel dealer for new decals and placards.

NOTE

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

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

DO NOT fillthe fuel tankto capacity.Allowroom 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.

Ground Control Box

Controls for operating the MHP12/34J from the ground, are located on the right side of the turnta ble.

NOTE

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

Emergency Stop: Press the EMERGENCY STOP switch cover down, at any time, under any conditions, and the entire machine stops, and nothing moves. This emergency stop switch cover must be up and the switch turned on for anything on the MHP12/34J to work.

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

Choke/Cold Start: Hold the switch UP while you start an engine that is at ambient air temperature (a "cold" engine). This will choke the engine.

Master Key Switch: This switch works like an automobile ignition switch. Hold it at START until the engine starts, then release it to ON. (-) Turn the Master Key Switch to OFF (O) if the platform is to stay in one position for a long time, that will turn the engine off and save fuel.

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

Stablizer / Boom Selector Switch: Must be in Stablizer (outrigger) position (down) for the outriggers to wor k. Once outriggers are down and set the switch must be placed in the boom (up) position for the booms to work.

Control switches 7 through 10 are the platform movingswitches.Each isa three position,momen tary contact, normally OFF switch.

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

10.

Slew: LEFT rotates the entire turntable and boom to the left. RIGHT rotates the entire turntable and boom to the right.

11.

Lift Enable: The platform can only be raised when this light is lit. When this light is not lit the platform will not raise because the outriggers are not proper ly set.

NOTE

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

Lower Boom : UP raises the lower boom. DOWN lowers the lower boom.

Upper Boom: UP raises the upper boom. DOWN lowers the upper boom.

Platform Control Box

Controls for operating the MHP12/34J from the platform are located on the platform control box, with the exception of the footswitch which is on the platform floor.

NOTE

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

Choke/Cold Start: Hold the switch UP while you start an engine that is at ambient air temperature (a "cold" engine). This will choke the engine.

Anti-Restart: This switch works like an automobile ignition switch.Hold it at START until the engine starts, then release it to ON (-). If the engine dies in ON, the key must be turned to OFF (O) before it will go back to START. Turn the switch to OFF if the platform is to stay in one position for a long time, that will tur n the engine off and save fuel.

Emergency Lower: If the engine stops and cannot be restarted, hold the switch down and this will lower the upper and lower booms (not the jib boom). To slew during emergency lower operate emergency lower and slew switches together.

Upper Boom: UP raises the upper boom. DOWN lowers the upper boom.

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

10.

Slew: LEFT rotates the entire turntable and boom to the left. RIGHT rotates the entire turntable and boom to the right.

Lift Enable: The platform can only be raised when this light is lit. When this light is not lit the platform will not raise because the outriggers are not proper ly set.

12.

Foot Switch: You must step down on the foot switch, and hold it down when you use any platform control that causes the platform to move.

Items 6 through 10 are the platform moving switches.Each isa threeposition, momentary con tact, normally OFF switch.

11. Options

■

Bi-Energy

This option consists of a column-mounted 24V DC motor located under the fiberglass covers. This provides an alternative power source to the gasoline engine.The DC motor is powered by four “Deep Cycle Traction Batteries” and an automatic battery charger that are also mounted on the column under the fibreglass covers.

DC motor operation

❑

A switch (see Figure 11.1) is used to select either the gasoline or the DC motor. If the DC motor is selectedthe gasolineengine willnot start andif the gasoline engine is selected the DC motor will not run.

Batteries

❑

Since the Bi-Energy MHP12/34J is powered by “DeepCycle Traction Batteries”particular attention should be paid to the batteries on-board chargerto ensure proper operation.

The batteries are enclosed beneath covers on either side of the column assembly. (See Figure

11.3). Raise the covers to gain access to the batteries.

NOTE

These covers should also be raised whilst charging to allow the gasses to escape.

Figure 11.1 - Gasoline / DC Motor Select

Switch

Once the DC mode is selected the motor will then powerallof the functionsincludingthe stabilisersin the normal manner, the only difference being that the DC motor will only “run” when a function is selected.

There is a “Master Battery Isolator Switch” mountedbelow themain lowercontrolstation, (see Figure11.2).This willshutdownthe DCmotorifit is turned to the “Off” position.

Figure 11.3 - MHP12/34J Covers Raised

DANGER

Lead-acid batteries contain sulphuric acid which will damage eyes or skin on contact. When working around batteries, ALWAYS wear a face shield to avoid acid in eyes. If acid contacts eyes, flush immediately with clear water and get medical attention.

Wear rubber gloves and protective clothing to keep acid off skin, if acid contacts skin, wash off immediately with clear water

Lead-acid batteries produce flammable and explosive gasses. NEVER allow smoking, flames or sparks around batteries.

NOTE

Refer to the maintenance section of the Repair Parts manual for more information on battery care and maintenance.

Battery charger

Figure 11.2 - Battery Isolate Switch

MHP12/34J – 11447A page 11 - 1

The Bi-Energy MHP12/34J is fitted with an on-board automatic battery charger (see Figure

11.4).The charger has an electronic timer that will

Page 56

11. Options

enable it to completely re-charge the batteries and automatically turn off after the cycle is completed.

Figure 11.4 - On-Board Battery Charger

Thebattery chargeris fitted withan “interlock”.This means that during the charging cycle all functions on the machine are inoperative and will remain so until the charger is switched off.

The charging cycle may last from 1 to 12 hours depending on the state of the batteries. If the charging cycleshould exceed16 hours ( indicating a fault) the charger will automatically shut down and the batteries should be checked.

DO NOT re-charge the batteries unless the electrolyte level has been checked.

DO NOT allow smoking, flames or sparks around batteries.

DO ENSURE the covers are in the open position during charging to allow gasses to escape.
