WARNING: □

DANGER

^ GENERAL HAZARDS ^

For safety reasons, Generac recommends

that the installation, initial start-up and mainte nance of this equipment is carried out by a Generac Authorized Service Dealer.

The engine exhaust fumes contain carbon monox

ide. which can be DEADLY. This dangerous gas, if

breathed in sufficient concentrations, can cause

unconsciousness or even death. This exhaust sys tem must be installed properly, in strict compli

ance with applicable codes and standards. Following installation, you must do nothing that might render the system unsafe or in noncompli

ance with such codes and standards. The genera tor compartment must be completely vapor sealed from the vehicle interior. There must be no possi bility of exhaust fumes entering the vehicle interi or. Never operate this equipment with a leaking or defective exhaust system.

Keep hands, feet, clothing, etc., away from drive belts, fans, and other moving or hot parts. Never remove any drive belt or fan guard while the unit is operating.

Adequate, unobstructed flow of cooling and venti

lating air is critical to correct generator operation and is required to expel toxic fumes and fuel vapors from the generator compartment. Without sufficient cooling airflow, the engine/generator quickly overheats, which causes serious damage to the generator. Do not alter the installation or per mit even partial blockage of ventilation provisions, as this can seriously affect safe operation of the generator.

When working on this equipment, remain alert at

all times. Never work on the equipment when you are physically or mentally fatigued.

Inspect the generator regularly, and contact your

nearest Generac Authorized Service Dealer imme diately for parts needing repair or replacement.

Before performing any maintenance on the genera

tor, disconnect its battery cables to prevent acci dental start up. Disconnect the cable from the bat tery post indicated by a NEGATIVE, NEG or (-) first. Reconnect that cable last.

Never use the generator or any of its parts as a

step. Stepping on the unit can stress and break parts, and may result in dangerous operating con ditions from leaking exhaust gases, fuel leakage, oil leakage, etc.

ELECTRICAL HAZARDS

• The generator covered by this manual produces dangerous electrical voltages and can cause fatal electrical shock. Avoid contact with bare wires, ter minals, connections, etc., while the unit is running. Ensure all appropriate covers, guards and barriers are in place before operafing the generator. If you must work around an operating unit, stand on an insulated, dry surface to reduce shock hazard.

• Do not handle any kind of elecfrical device while standing in water, while barefoot, or while hands or feet are wet. DANGEROUS ELECTRICAL SHOCK MAY RESULT.

• During installation onto the vehicle, have the gen erator properly grounded (bonded) either by solid mounting to the vehicle frame or chassis, or by means of an approved bonding conductor. DO NOT disconnect the bonding conductor, if so equipped. DO NOT reconnect the bonding conduc tor to any generator part that might be removed or disassembled during routine maintenance. If the grounding conductor must be replaced, use only a flexible conductor that is of No. 8 American Wire Gauge (AWG) copper wire minimum.

• In case of accident caused by electric shock, imme diately shut down the source of electrical power. If this is not possible, attempt to free the victim from the live conductor. AVOID DIRECT CONTACT WITH THE VICTIM. Use a nonconducting imple ment, such as a rope or board, to free the victim from the live conductor. If the victim is uncon scious, apply first aid and get immediate medical help.

• Never wear Jewelry when working on this equip ment. Jewelry can conduct electricity resulting in electric shock, or may get caught in moving com ponents causing injury.

FIRE HAZARDS

For fire safety, the generator must be installed and

maintained properly. Installation always must comply with applicable codes, standards, laws and regulations. Adhere strictly to local, slate and national electrical and building codes. Comjdy

with regulations the Occupational Safety and

Health Administration (OSHA) has establislu'd.

Also, ensure that the generator is installed in

accordance with the manufacturer’s instructions and recommendations. Following proper installa tion, do nothing that might alter a safe installation and render the unit in noncompliance with the aforementioned codes, standards, laws and regu lations.

Keep a fire extinguislicr in the vehi('le at all times.

Extinguishers rated “ABC’’ by the National Fire Protection Association are appropriate for use on the recreational vehicle generator elei’lrical sys tem. Keep the extinguisher properly charged and be familiar with its use. If you have any question pertaining to fire extinguishers, consult your local fire department.

EXPLOSION HAZARDS

Do not snroke around the generator. Wi]re rqr any

fuel or oil spills immediately. Ensure that no com bustible materials arc left in the generator com partment, or on or near the generator, as FIRE or EXPLOSION may result. Keep the area surround ing the generator clean and free from debris.

Gasoline is extremely FLAMMABLE and its vapors

are EXPLOSIVE, Do not permit smoking, open flame, sparks or any source of heat in the vicinity

while handling gasoline. Comply with all laws gov

erning the storage and handling of gasoline.

This generator may use liquid propane (LP) gas as

a fuel. LP gas is highly EXPLOSIVE. The gas is heavier than air and tends to settle in low areas

where even the slightest spark can ignite the gas

and cause an explosion.

GENERAL

INFORMATION

1.2 GENERATOR APPLICABILITY

These generators have been designed and manufac tured for supplying electrical power for recreational vehicles. You should not modify the generator or use it for any application other than for what it was designed. If there are any questions pertaining to its

application, write or call the factory. Do not use the unit until you have been advised by competent authority.

DANGER

For fire safety, the generator must have been

properly installed in compliance with ANSI

119.2-1975/NFPA 501C-1974, "Standard for Recreational Vehicles, Part III - Installation of Electrical Systems." The generator also must have been installed in strict compliance with

the manufacturer's detailed installation instruc tions. After installation, do nothing that might render the unit in noncompliance with such codes, standards and instructions.

You can use your generator set to supply electrical power for operating one of the following electrical

loads:

• PRIMEPACT 70G: 120 and/or 240 volts, single phase, 60 Hz electrical loads. These loads can require up to 7000 watts (7.0 kW) of power, but cannot exceed 58.3 AC amperes of current at 120 volts or exceed 29.2 AC amperes at 240 volts.

• PRIMEPACT 70LP: 120 and/or 240 volts, single phase, 60 Hz electrical loads. These loads can require up to 6600 watts (6.6 kW) of power, but cannot exceed 55 AC amperes of current at 120

volts or exceed 27.5 AC amperes at 240 volts.

-------

M. CAUTION M

Do not overload the generator. Some installa tions may require that electrical loads be alter nated to avoid overloading. Applying exces sively high electrical loads may damage the generator and may shorten its life. Add up the rated watts of all electrical lighting, appliance, tool and motor loads the generator will power at one time. This total should not be greater than the wattage capacity of the generator. If an electrical device nameplate gives only volts and amps, multiply volts times amps to obtain watts (volts X amps = watts). Some electric motors require more watts of power (or amps of current) for starting than for continuous operation.

-----------------

1.3 INSTALLATION

This Owner's Manual has been prepared under (he assumption that a competent, qualified technician installed the generator into an induslrial vehicle. We also assume the installer complied with all apirlicable codes, standards and regulations pertaining to instal lation.

An INSTALLATION MANUAL was sliipped witli llie generator. That Manual contains inanufactnrer's

instructions and recommendations for installing the unit into an industrial vehicle. After installation, installers should forward the Installation Manual to Owners/Operators for their information.

Owners/Operators have the responsibility to make sure that nothing is done that might render the instal lation unsafe or in non-complianc(' with apirlicable codes, standards and instructions.

1.4 SAFETY

Before using the generator set, carefully read GEN ERAL SAFETY RULES inside the cover. Comply with these RULES to prevent accidents and damage to equipment and/or property. Generac suggests copy ing and posting the GENERAL SAFE'l'Y RULES to

1.5 GENERATOR AC CONNECTION

SYSTEM

These air-cooled generator sets are equipped with dual stator AC power windings. These two stator windings supply electrical power to customer electri cal loads by means of a dual 2-wire connection sys tem.

Generators may be installed to provide the following outputs;

1) 120 VAC loads only — one load with a mirxiinum total wattage requirement equal to the generator’s rated power output (in watts), and 120V across the

generator output terminals.

2) 120/240 VAC loads — one load with a niiiximum

total wattage requirement equal to the generator’s rated power output, and 240 V across the generator output terminals; or two seperate loads, each willi a maximum total wattage requirement equal to half of the generator’s rated power output (in watts), and

120 V across the generator output terminals.

NOTE

Some installations using a “shared” fuel tank may have a generator fuel pickup tube that is shorter than the vehicle engine’s pickup tube. Such an

arrangement causes the generator engine to “run

out of gas” while adequate fuel for the vehicle

remains in the tank.

To reduce lead and carbon deposits use high quality UNLEADED gasoline with the generator. Leaded REGULAR grade gasoline is an acceptable substitute.

NOTE:

Using unleaded gasoline contributes to longer engine valve life by reducing lead and carbon deposits.

-A CAUTION A-

Generac does not recommend using any

gasoline containing alcohol (such as "gasohol"). If you use any gasoline containing alcohol, it must not contain more than 10 percent ethanol, and it must be removed from the generator during storage. Do NOT use any gasoline containing methanol. If you use gasoline with alcohol, inspect more frequently for fuel leaks and other abnormalities.

♦ 1.6.2 ENGINE OIL REQUIREMENTS

________________

Use only high quality detergent oil classified “For

Service SF” and with an oil viscosity rating of SAE

NOTE:

If this generator has been reconnected for dual voltage AC output (120/240 volts), you can install line breakers having an amperage rating that is different than that stated above. The replacement

line breakers consist of two separate breakers with

a connecting piece between the breaker handles

(so that both breakers will operate at the same time). If the unit is reconnected for dual voltage, it is no longer RVIA listed.

2.2 OPTIONAL REMOTE

START/STOP PANEL

A remote mounted Start/Stop Panel (Figure 2.2) is

available that allows you to start and stop the gener

ator engine conveniently from inside the vehicle. The

remote panel includes a Start/Stop switch,

hour meter, generator run lamp and a wire harness.

♦ 2.3.2 PRECHOKE

The choke system also has a temperature-sensitive metal strip that adjusts choke valve angle according to ambient temperatures (i.e., in cold ambient tem peratures, choke valve closes more). Once the engine starts, an element heats the temperature-sensitive strip to a normal operating condition, opening the choke valve. This may take about three minutes in cooler weather.

2.4 BEFORE STARTING THE ENGINE

NOTE:

Instructions and information in this manual assume the generator has been properly installed, connected, serviced, tested and adjusted by a qualified installation technician or installation contractor.

♦ 2.4.1 INSTALLATION___________________________

Generator installation must have been properly com pleted so it complies with all applicable codes, stan dards and regulations and with the manufacturer's recommendations.

2.3 AUTOMATIC CHOKE

This engine is equipped with an automatic choke that consists of two main components: a choke solenoid and irrechoke.

♦ 2.5.1 CHOKE SOLENOID

During engine cranking (Start/Stop switch at START), a solid-state choke module signals the choke solenoid to activate and cycle (choke on/chokc off) until the engine starts. The choke solenoid thus opens and closes the carburetor choke valve only when the engine is cranking. When (he engine starts, (he choke sto[3S cycling.

♦ 2.4.2 ENGINE LUBRICATION

Have the engine crankcase properly serviced with the recommended oil before starting. Refer to Section

1.6.3 (Page 6) and Sections 3.1 and 3.2 (Page 11) for

oil servicing procedures and recommendations.

-------

M. CAUTION ik

Any attempt to crank or start the engine before

you have properly serviced it with the recom mended oil may result in an engine failure.

♦ 2.4.3 FUEL SUPPLY____________________________

The engine must have an adequate supply of proper fuel to operate. Before starting it, check that sufficient fuel is available.

Depending on the installation, the generator may have either a separate fuel tank, or it may “share” the vehicle engine’s fuel tank.

♦ 2.4.4 COOLING AND VENTILATING AIR

Air inlet and outlet openings in the generator com partment must be open and unobstructed for contin ued proper operation. Without sufficient cooling and ventilating airflow, the engine/generator quickly over heats. which causes it to shut down and may damage the generator.

♦ 2.4.5 ENGINE EXHAUST GAS_____________________

Before starting the generator engine, you should be sure there is no way for exhaust gases to enter tlie vehicle interior and endanger people or animals. Close windows, doors and other openings in the vehi cle that, if open, might permit exhaust gases to enter the vehicle.

DANGER

The generator engine gives off DEADLY carbon monoxide gas through its exhaust system. This dangerous gas, if breathed in sufficient concen trations, can cause unconsciousness or even death. Never operate the generator set with the vehicle inside any garage or other enclosed area. DO NOT OPERATE THE GENERATOR IF THE EXHAUST SYSTEM IS LEAKING OR HAS BEEN DAMAGED. SYMPTOMS OF CARBON MONOX IDE POISONING ARE (a) inability to think coher ently; (b) vomiting; (c) twitching muscles; (d) throbbing temples; (e) dizziness; (f) headaches; (g) weakness; and (h) sleepiness. IF YOU FEEL ANY OF THESE SYMPTOMS, MOVE INTO FRESH AIR IMMEDIATELY. IF SYMPTOMS PERSIST, GET MEDICAL HELP.

2.5

Read the vehicle manufacturer’s instructions. The

owner/operator should become familiar with the vehicle in which this generator is installed. Differences exist between vehicles. For example,

some vehicles may use a transfer switch to isolate

dockside power from the generator, while other vehicles may use an isolating receptacle. Some vehicles may be equipped with a DC converter which allows the generator to power certain DC lighting and other DC loads.

To crank and start the generator engine, proceed as follows:

1. Turn OFF electrical loads using the means pro

If starting from the generator control panel, turn OFF loads by setting the generator’s main circuit breaker to the OFF (or open) position. If starting from a remote panel, turn OFF loads using the means provided in the vehicle (such as a main cir cuit breaker). Electrical load circuits will be turned ON after the generator has started, stabi lized and warmed up.

STARTING THE GENERATOR

NOTE:

vided in your vehicle (such as a main line circuit breaker or transfer switch).

NOTE:

Section 2 - Operation

If you have not started the engine in more than two weeks, press the Fuel Pump Primer switch and hold it for about 10 seconds. However, if the engine is warm, skip Step 2.

To crank and start the engine, hold the start/stop switch at START. Release the switch when the engine starts.

-------

Mk CAUTION

If the engine does not start after it has been

^ cranking for 15 seconds, release the Start/Stop

switch and wait 1 minute before trying again. Holding the switch for longer than 15 seconds can damage the starter motor.

Let the engine run at no-load for a few minutes to stabilize and warm up.

Turn ON electrical loads using the means provided (such as a main circuit bicaker oitransfer switch).

---------------

OPERATION

2.6 STOPPING THE GENERATOR

1. Turn OFF all electrical loads using the means provided (such as a main circuit breaker or transfer switch).

Let generator run at no-load for a few minutes, to

stabilize internal engine generator temperatures. Place the Start/Stop switch in its STOP position.

3. The engine will come to a complete stop.

2.7 APPLYING LOADS TO GENERATOR

When applying electrical loads to the generator, observe these guidelines:

• Before applying electrical loads, let the generator stabilize and warm up for a minute or two.

“ DO NOT overload the generator.

♦ 2.7.1 LETTING THE ENGINE STABILIZE

The generator supplies correct rated voltage only at the proper governed speed. Some electrical appli ances may be extremely sensitive to voltage. Incorrect voltages can damage such appliances.

If electrical loads are applied at reduced operating speeds, such loads imposed on the engine when suf ficient power is not available may shorten engine life. Never turn ON electrical loads until after the genera tor engine has started and stabilized at no-load.

• 2.7.2 DO NOT OVERLOAD THE GENERATOR

You can read the rat- ’ waltage/amperage capacity of your generator on the generator data decal (see Section 1.1 on Page 4).

Applying electrical loads in excess of the unit’s rated capacity will cause the engine/generator to automati cally shut down.

To avoid overloading, add up the wattage of all con nected electrical lighting, appliance, tool and motor loads. This total should not be greater than the gen erator’s rated wattage capacity.

• Most lighting, appliance, tool and motor loads indi cate their required watts on their nameplate or

data plate. For light bulbs, simply note the wattage rating of the bulb.

• If a load does not show its rated wattage, multiply

that load’s rated VOLTS times AMPS to obtain WATTS.

• Induction type motors (such as those that run the

vehicle’s furnace fan, refrigerator, air conditioner, etc.) need about 2-1/2 times more watts of power for starting than for running (for a few seconds during motor starling). Be sure to allow for this when connecting electrical loads to the generator. First, figure the watts needed to start electric motors in the system. To that figure, add the run ning wattages of other items lliat will be operated by the generator.

• Do not apply heavy electrical loads for the first two

or three hours of operation.

2.8 PROTECTION SYSTEfVIS

• 2.8.1 LOW OIL PRESSURE SWITCH

I'his switch (Figure 2.3 on page 10) has normally closed (N.C.) contacts that arc held open by engine oil l)i essure during cranking and operating. Should oil j^ressure drop below a ¡preset level, switch contacts close, and the engine automatically shuts down. The unit should not be restarted until oil is added.

_______________

♦ 2.8.2 HIGH TEMPERATURE SWITCH

_______________

This switch (Figure 2.3), which has normally open

(N.O.) contacts, is mounted near the oil filter. The contacts close if the temperature should exceed approximately 284° F (140° C), initiating an engine shutdown.

♦ 2.8.3 FIELD BOOST

The Controller Circuit Board houses a field boost diode and resistor that are not part of the automatic choke circuit. These two components are part of a “field boost” circuit (Figure 2.4). During engine cranking only, a positive DC (battery) voltage is deliv ered through the diode, resistor, brushes and slip rings, and the generator rotor. Application of this voltage to the rotor “flashes the field” whenever it is started. Flashing of the field each time the generator starts makes sure that a sufficiently strong magnetic field is available to produce “pickup” voltage in the stator windings.

♦ 2.8.4 OVERVOLTAGE PROTECTION________________

A solid-state voltage regulator (Figure 2.5) controls the generator’s AC output voltage. This regulator sup plies an excitation current to the rotor. By regulating the rotor’s excitation current, the strength of its mag netic field is regulated and, in turn, the voltage deliv ered to connected electrical loads is controlled. When the AC frequency is 50 Hertz, voltage is regulated at

115 volts.

The voltage regulator also incorporates a “voltage surge protection circuit.” This circuit prevents trou blesome surges in the generator AC output voltage. Voltage surge is a common cause of damage to elec tronic equipment.

• 2.8.5 25-HOUR BREAK-IN PERIOD

_____________

The first 25 hours of operation is the break-in period for the generator. Properly breaking in the generator is essential to minimize fuel consumption and pro

vide maximum engine performance. During this 25-

hour break-in period, follow this procedure:

• Run the unit at varying electrical loads to help seat the engine piston rings properly.

• Check the engine oil level frequently. Add oil if needed. It is normal for the generator engine to consume more oil than is normal until the piston rings have properly seated.

• For the 75-hour operation following the break-in period, avoid light electrical loads. Load the generator at 50 percent (or more) of its rated wattage capacity. Repeated light loads during these

75 hours can cause improper seating of engine pis ton rings, resulting in blowby and high oil con sumption.

• After operating the unit for 25 hours, complete the tasks recommended under Section 2.8.6.

♦ 2.8.6 25-HOUR CHECK-UP

After the 25-hour break-in period, contact a Gcncrac Authorized Service Dealer for the following mainte nance. The vehicle owner is responsible for any charges:

• Change the engine crankcase oil and oil filter.

• Check all fluid levels.

• Inspect the cooling and ventilation openings.

• Check the engine ignition system.

• Inspect the entire electrical system.

• Inspect the engine exhaust system.

• 2.8.7 OPERATION IN HIGH GRASS OR BRUSH

-------

M. WARNING Ék

-----------------

Never operate the generator while the vehicle is parked over high grass, weeds, brush,

leaves or any other combustible substance. Such materials can ignite and burn from the heat of the exhaust system. The generator exhaust system becomes extremely hot dur ing operation and remains hot for a long time after it has shut down.

3.1

CHECKING THE ENGINE OIL LEVEL

For oil capacities and requirements, see “Engine Oil Requirements,” Section 1.6.2 (Page 6). Check the engine crankcase oil level at least every eight hours of operation, or before you use it. To check the engine

oil level, proceed as follows (see Figure 3.1):

Be sure the generator is as level as possible.

Remove the dipstick and wipe it dry with a clean,

lint-free cloth. Install and tighten the dipstick cap; then, remove

3. it again. The oil level should be at the dipstick “Full” mark.

If necessary, remove the oil fill cap on the rocker

4. cover and slowly adcf oil until it reaches the dip stick “Full” mark. DO NOT FILL ABOVE THE

“FULL’ MARK.

-------

ik CAUTION Mk---------------

Never operate the engine with the oil level

below the "Add" mark on the dipstick. Doing this could damage the engine.

3.2 CHANGING THE ENGINE OIL

AND/OR OIL FILTER

• Change the engine oil after the first 25 hours of

operation (after the 25-hour break-in period, see

Section 2.8.5, Page 10). Thereafter, change the oil every 100 operating hours. Change the oil more frequently if operating consistently under heavy load or at high ambient temperatures.

• Change the engine oil filter after the first 25 hours

of operation, and every 100 operating hours there after.

To change the oil and/or oil filter, proceed as follows:

1. Run the engine until it is thoroughly warmed up (at least five minutes) then shut OFF

the engine.

2. With (he engine still warm from running, remove the oil drain plug (Figure 3.1). Drain the oil into a suitable conlainer.

3. After the oil lias drained, replace the oil drain plug. (II only changing the oil, go to step 7.)

4. With the oil drained, remove the old oil filter by ¡uming it counterclockwise (Figure 3.2 on page 12).

5. Apply a light coating of clean engine oil to the gas ket of the new filter.

6. Screw the new filter on by hand until its gasket lightly c'onlacts the oil filter adapter. Then, tight en the filter an additional 3/4 to one turn.

7. Remove the dipstick and fill crankcase with the jn oper type and amount of recommended oil (see Seedion 1.6.2. Page 6). Tlie engine crankcase can hold aboul 1.4 liters. DO NOT FILL ABOVE THE d^TJLi: MARK.

ik WARNING Ék

Be sure to reinstall the muffler plug tightly.

Engine vibration could cause a loose plug to

fall out. Without the plug in place, hot engine

exhaust is directed out the opening. This hot exhaust, depending on the installation, could be directed to areas not able to withstand the extreme heat such as wooden floor boards or other flammable material. This could result in a

fire.

------

3.8 CLEANING THE GENERATOR

Keep the generator set as clean and dry as possible.

Protect the unit against excessive dust, dirt, corrosive vapors, road splash, etc. Permitting dirt and mois ture to accumulate on generator windings will have an adverse effect on the insulation resistance of those windings.

When moisture is allowed to remain in contact with windings, some of the moisture will be retained in voids and cracks in the insulation. This causes a reduced insulation resistance and will eventually cause problems. Dirt will make the problem worse, since dirt tends to hold moisture in contact with windings. Salt (as from sea air) also will worsen the problem since it tends to absorb moisture from the air. Salt and moisture, when combined, form a good electrical conductor.

---------

Ml caution M

Do NOT use a forceful spray of water to clean

the generator. Water will enter the generator interior and cause problems, and may also cont aminate the generator fuel system.

-------------------

3.9 BATTERY MAINTENANCE

All lead-acid batteries will discharge when not in use. The generator battery should be inspected as follows:

♦ 3.9.1 WEEKLY________________________________

• Inspect the battery posts and cables for tightness and corrosion. Tighten and clean as necessary.

• Check the battery fluid level of unsealed batteries and, if necessary, fill with Distilled Water Only. Do not use tap water in batteries.

♦ 5.9.2 EVERY SIX MONTHS

• Have the state of charge and condition checked.

This should be done with an automotive-type bat

tery hydrometer.

Servicing of the battery is to be performed or supervised by personnel knowledgeable of batter ies and the required precautions. Keep unautho rized personnel away from batteries.

1 «4 Generac’ Power Systems, Inc.

_______________________

NOTE:

Damage will result if the battery connections are made in reverse.

DANGER

Do not dispose of the battery in a fire. The battery is capable of exploding. Storage batter ies give off explosive hydrogen gas. This gas

can form an explosive mixture around the bat tery for several hours after charging. The slightest spark can ignite the gas and cause an explosion. Such an explosion can shatter the battery and cause blindness or other injury. Any area that houses a storage battery must be properly ventilated. Do not allow smoking, open flame, sparks, or any spark producing

tools or equipment near the battery. Discharge

static electricity from your body before touch ing the battery by first touching a grounded metal surface.

A battery presents a risk of electrical shock

and high short circuit current. The following precautions are to be observed when working

on batteries:

• Remove watches, rings or other metal objects;

• Use tools with insulated handles;

• Wear rubber gloves and boots;

• Do not lay tools or metal parts on top of the

battery;

• Disconnect any charging source prior to connecting

or disconnecting battery terminals; and

• Do not use any jumper cables or booster battery to crank and start the generator engine. If any battery has discharged, remove it for recharging.

-----

LL WARNING ik

Do not open or mutilate the battery. Released

electrolyte has been known to be harmful to the skin and eyes, and to be toxic.

The electrolyte is a dilute sulfuric acid that is

harmful to the skin and eyes. It is electrically conductive and corrosive. The following procedures are to be observed:

• Wear full eye protection and protective clothing;

• Where electrolyte contacts the skin, wash it off

immediately with water;

• Where electrolyte contacts the eyes, flush thoroughly and immediately with water and seek medical attention; and

• Spilled electrolyte is to be washed down with an acid neutralizing agent. A common practice is to

use a solution of 1 pound (500 grams) bicarbonate

of soda to 1 gallon (4 liters) or water. The bicar

bonate of soda solution is to be added until the

evidence of reaction (foaming) has ceased. The

resulting liquid is to be flushed with water and the area dried.
