DANGER

CARBON MONOXIDE

Using a generator indoors CAN KILL YOU IN MINUTES.

Generator exhaust contains carbon monoxide (CO). This is a poison you cannot see or

smell. If you can smell the generator exhaust, you are breathing CO. But even if you cannot

smell the exhaust, you could be breathing CO.

• NEVER use a generator inside homes, garages, crawlspaces, or other partly enclosed

areas. Deadly levels of carbon monoxide can build up in these areas. Using a fan or

opening windows and doors does NOT supply enough fresh air.

• ONLY use a generator outside and far away from windows, doors, and vents. These

openings can pull in generator exhaust.

Even when you use a generator correctly, CO may leak into the home. ALWAYS use a

battery-powered or battery-backup CO alarm in the home.

If you start to feel sick, dizzy, or weak after the generator has been running, move to fresh

air RIGHT AWAY. See a doctor. You could have carbon monoxide poison.

1.11 Grounding the Generator

The generator should be grounded to a good ground

source in compliance with local regulations.

Use #8 AWG wire and secure one end to the ground

terminal (a) provided on the generator frame and the

other end to a suitable ground source.

1.10 Application and Power Requirements

This generator is designed to operate single-phase,

60 Hz appliances running at 120 and 240 VAC.

CAUTION: Do not exceed the continuous rated output

of the generator. Damage to tools or generator will occur.

Refer to Section 1.9

Technical Data.

Check the nameplate or label provided on tools and

appliances to make sure their power requirements are

met by the power output of the generator. If the wattage

is not given for a particular tool or appliance, contact the

tool manufacturer for wattage requirements.

Some appliances and tools require a surge of current

when starting. This means that the amount of power

needed to initially start the equipment is larger than the

power required to keep it running. The generator must be

capable of supplying this "surge" current. Other types of

appliances require more power than is actually stated on

their nameplate.

Chart 1 is offered only as a general guideline to help you

determine power requirements for different types of

equipment. Check with your nearest WACKER dealer, or

contact the manufacturer or dealer of the tool or appli-

ance, if you have questions regarding power require-

ments.

CAUTION: DO NOT exceed the rated current limit of

any receptacle.

CAUTION: If a tool or appliance does not reach full

speed within a few seconds after it is switched on, turn it

off immediately to avoid damage.

Chart 1

Approximate Starting Power Requirements

• Incandescent lights and appliances such

as irons and hot plates, which use a

resistive-type heating element, require the

same wattage to start and run as is stated

on their nameplates.

• Fluorescent and mercury lamps require

1.2–2 times their stated wattage to start.

• Electrical motors and many types of

electrical tools often require a large

starting current. The amount of starting

current depends on the type of motor and

its use.

• Most electrical tools require 1.2–3 times

their stated wattage for running.

• Loads such as submersible pumps and air

compressors require a very large force to

start. They need as much as 3–5 times the

wattage stated on the nameplate in order

to start.

1A-10

1A OPERATION GS8.5V / GS9.7V

1.12 Generator Derating

All generators are subject to derating for altitude and

temperature. Internal combustion engines, unless modi-

fied, run less efficiently at higher altitudes due to the lack

of air pressure. This translates into a lack of power and

thus reduction in generator output. Temperature affects

both engine and generator performance. As temperature

increases, an engine will run less efficiently and the more

resistance will be found in the electrical components.

Therefore, as the temperature increases, the output of

the generator decreases. Altitude also affects the cooling

capacity of air —the higher the altitude the less dense the

air is and thus the lower its ability to transfer heat.

For every increase in altitude of 1650 feet (500 m) above

3300 feet (1000 m), the output of the generator will be

reduced by 3%. For every increase of 9° F

(5° C) in ambient temperature above 104° F (40° C), the

output of the generator will be reduced by 3%. Use the

tables shown for altitude and temperature deration fac-

tors. It may be necessary to consider both altitude and

ambient temperature deration factors to determine true

generator output.

1.13 Use of Extension Cords

When a long extension cord is used to connect an

appliance or tool to the generator, a voltage loss oc-

curs—the longer the cord, the greater the voltage loss.

This results in less voltage being supplied to the appli-

ance or tool and increases the amount of current draw or

reduces performance. A cord with a larger cross section

will reduce the voltage loss.

CAUTION: Operating equipment at low voltage can

cause it to overheat.

Use Table 3 as a guide for selecting proper cable size.

Use only extension cords rated for outdoor use.

1.14 Indoor Installation

If the generator must be installed indoors, adequate

ventilation or exhaust hoses must be provided. When

venting exhaust fumes, make sure the exhaust piping is

large enough to prevent excessive back pressure to the

engine. Back pressure reduces engine efficiency and

may cause the engine to overheat.

Exhaust gas from the engine contains poisonous

carbon monoxide gas; exposure to carbon monox-

ide can cause loss of consciousness and may lead

to death. Never run generator indoors or in an

enclosed area unless adequate ventilation, through

such items as exhaust fans or hoses, is provided.

When installed indoors, steps to prevent fire and explo-

sion such as, providing a good earthen ground, removing

all flammable materials near generator, and using only

electric cables in good condition, must be observed.

See

Section 1.3 Operating Safety.

1.15 Outdoor Installation

Place the generator in an area where it will not be

exposed to rain, snow, or other forms of moisture. Make

sure it is positioned on firm, level ground so it will not slide

or shift. Position engine exhaust away from areas where

people may be present.

If operating the generator inside a tunnel or deep trench,

make sure there is adequate ventilation. Precautions

similar to those required when operating indoors may be

necessary.

1.16 Recommended Battery

This generator is shipped without a battery.

The recommended battery to be used is:

1.18 Main Circuit Breaker

The generator is protected by a main breaker (b) located

on the control panel. The circuit breaker protects the

generator from severe overloads or short circuits. If the

circuit breaker opens, turn the engine off immediately

and determine the cause before restarting. Check the

appliances and tools attached to the generator for de-

fects and make sure their power requirements do not

exceed the power rating of the generator or the current

limit of the receptacles.

When the circuit breaker opens (0), the breaker lever will

snap down. To reset circuit breaker, lift lever up (I).

1.19 Ground Fault Circuit Interrupt (GFI)

Each of the two 120V, 15 Amp receptacles (f) is pro-

tected by both a ground fault circuit interrupt (GFI) and a

thermal overload. The GFI shuts off the power to the

receptacle when a ground fault occurs in the generator or

to a piece of equipment attached to the generator. The

thermal overload (i) will trip (pop out) if too much current

is drawn through the receptacle, as in a short to ground.

The GFI should be tested for proper operation every time

the generator is used.

To test GFI:

Start generator. Turn the auto idle to the “0” (off) position.

Push in TEST button (g) on receptacle. The RESET

button (h) will pop out. Power is now off at the recep-

tacles. If the RESET button does not pop out, the GFI is

not working. Do not run generator until the problem can

be corrected. To restore power to receptacles, push the

RESET button in.

If the RESET button pops out during operation, stop the

generator and check generator and equipment for de-

fects.

1A-13

GS8.5V / GS9.7V OPERATION 1A

1.22 Engine Auto Idle

The auto idle switch (a) automatically reduces engine

speed 5 seconds after all appliances or tools attached to

the generator have been turned off. Engine automatically

returns to full speed when a tool or appliance is turned

back on.

To turn auto idle feature on, push auto idle switch to ON

(I). This position is recommended while the generator is

running to minimize fuel consumption. To avoid extended

engine warm-up periods, keep switch OFF (0) when

starting the engine and until engine reaches operating

temperature.

1.23 Engine Speed

Generators require a fixed engine speed to maintain the

correct voltage. Engine speed is controlled by a governor

which automatically adjusts to varying loads on the

engine to maintain a constant speed of

3600 rpm. There is no throttle control. Use the Auto Idle

switch on the generator to control engine speed.

Note: The battery must have the appropriate charge

(nine volts minimum) for the generator governor to per-

form properly. If the generator starts but will not run at

speed, check battery charge.

1.21 Twist-lock Receptacles

240 volt power is available at twist-lock receptacles (m)

and (n). 120 volt power is also available at

twist-lock receptacle (n) and at receptacles (j

) and (j

The thermal overloads for (j

) and (j

) perform as de-

scribed for (i) in section 1.19

GFI

. However, protection

for the 240V receptacles is provided by overcurrent

circuit breakers, (c) for (m) and (d) for (n). If too much

current were to be drawn through either overcurrent

circuit breaker, the breaker would trip open. Correct the

source of the overcurrent before resetting the breaker.

To attach a power cord to a twist-lock receptacle, insert

plug into receptacle and turn it clockwise to lock it in

place.

1.20 Voltage Selection

The voltage selector switch (k) allows the generator to

operate in either single (120V) or dual voltage

(120/240V) mode.

In single voltage mode only the 120V twist lock and 120V

duplex receptacles are powered. The full rated power of

the generator is shared between the four receptacles.

In dual voltage mode both the 120V and 240V recep-

tacles are powered; however, only half the rated power

is available at the 120V GFI receptacles and half at the

120V twist lock receptacle. Full power is available at the

240V twist lock receptacle.

CAUTION: NEVER switch the voltage selector switch

with the main breaker on! This can cause arcing and can

damage the generator. Turn all tools and appliances off

and place main breaker in the “OFF” (open) position (0)

before changing the voltage switch position.

1.27 Engine Maintenance

The Periodic Maintenance Schedule below lists basic maintenance intervals for the engine and generator. Items

listed may be carried out by the layman with everyday hand tools. However, adjusting valve clearances may require

the skill of a professional engine mechanic. Read the engine manufacturer's Owner's Manual for more information on

engine maintenance.

1.29 Engine Lubrication

Check engine oil level daily, before starting engine. Add

oil as required.

To check oil level, place pump on a level surface. Clean

area around oil fill and remove dipstick. Pour oil (b)

slowly, checking oil level occasionally with dipstick. Fill to

full mark on dipstick (c). DO NOT overfill.

When measuring oil level, screw dipstick (d) firmly in

place until cap bottoms on tube.

1.30 Changing Oil Filter

Replace oil filter every 100 hours of operation.

Drain engine oil and replace with fresh oil before remov-

ing used oil filter. Remove used filter, and before install-

ing new filter, lightly oil filter gasket with fresh, clean

engine oil. Screw filter (a) on by hand until gasket makes

contact, then tighten an additional 1/2 to 3/4 turn. Start

and run engine to check for leaks. Stop engine. Recheck

oil level and add oil if required

(see 1.26 Engine

Lubrication).

Dispose of used oil in an appropriate man-

ner — consult local recycling center.

1.31 Servicing Air Cleaner

Service air cleaner frequently to prevent carburetor mal-

function.

NEVER run engine without air cleaner. Severe engine

damage will occur.

NEVER use gasoline or other types of low flash point

solvents for cleaning the air cleaner. A fire or explosion

could result.

The engine is equipped with a dual element air cleaner.

To service air cleaner:

1. Remove cover (b), knob (c), and retaining plate (d) .

2. Remove foam precleaner (e) from filter cartridge (f).

3. Wash precleaner in liquid detergent and water.

Squeeze dry in a clean cloth. Saturate precleaner in

engine oil; squeeze out excess oil. Replace precleaner

if it is damaged or heavily soiled.

4. To clean cartridge, remove and tap lightly on a flat

surface. Replace cartridge if it is damaged or heavily

soiled.

Note:

Do not use petroleum solvents to clean precleaner

or cartridge. Petroleum type solvents will damage them.

Do not use pressurized air to clean cartridge. Pressur-

ized air can also damage the cartridge.
