Generator Use; Ground System - Makita EG2250A Instructions For Use Manual

Oil Alert System (Fig. 14)
The engine can be damaged if there is an insufficient
amount of oil in the crankcase. The Oil Alert system
prevents this from happening by automatically stopping
the engine before the oil level in the crankcase falls below
the safe limit (the engine switch will remain in the "I (ON)"
position). When the oil alert system works, the oil level
warning lamp lights up in red. The oil level should always
be checked before each use, regardless of this Oil Alert
system.
If the engine stops and fails to restart, check the engine oil
level before troubleshooting in other areas.
NOTICE:
When the amount of oil in the crankcase is sufficient, the
pilot lamp lights up in green. When the amount of oil is
insufficient, the oil level warning lamp lights up in red. Be
sure to add oil before using the generator.
AC Circuit Breaker (Fig. 10)
The AC circuit breaker automatically turns off if there is a
short circuit or a significant overload of the generator at
the receptacle. If the AC circuit breaker is turns off
automatically, make sure that the appliance is working
correctly and does not exceed the rated load capacity of
the circuit before turning on the AC circuit breaker again.
The AC circuit breaker may be used to turn the generator
power on or off.
AC Circuit Protector (EG4550A, EG5550A,
EG6050A only) (Fig. 11)
The AC circuit protectors automatically turn off if there is a
short circuit or a significant overload of the generator at
the 26A 230V. If an AC circuit protector turns off
automatically, make sure that the appliance is working
correctly and does not exceed the rated load capacity of
the circuit before resetting the AC circuit protector on.

GENERATOR USE

Connections to a Building's Electrical
System
A qualified electrician must make the connections for
standby power to a building's electrical system. Make sure
that the connection isolates the generator power from the
utility power, and complies with all applicable laws and
electrical codes. A transfer switch, which isolates
generator power from utility power, can be purchased
through authorized Makita generator dealers.
WARNING:
Electrical current from the generator may backfeed
into the utility lines if connections to a building's
electrical system are made improperly. Such backfeed
may electrocute utility company workers or others
who come into contact with the lines during a power
outage, and the generator may explode, burn, or
cause fires when the utility power is restored. Consult
the utility company or a qualified electrician.

Ground System

Makita portable generators are equipped with a system
ground that connects generator frame components to the
ground terminals in the AC output receptacles. Since the
system ground is not connected to the AC neutral wire, if
the generator is tested by a receptacle tester, it will show
the same ground circuit condition as for a home
receptacle.
AC Applications
Before connecting an appliance or power cord to the
generator:
• Make sure that it is in good working condition. Faulty
appliances or power cords can cause electrical shock.
• If an appliance begins to operate in an abnormal
manner, becomes slow, or stops suddenly, turn it off
immediately. Disconnect the appliance, and determine
whether there is a problem with the appliance or if the
rated load capacity of the generator has been
exceeded.
• Make sure that the electrical rating of the tool or
appliance does not exceed the generator's rating.
Never exceed the maximum power rating of the
generator. Power levels between rated and maximum
may be used for no more than one hour.
NOTICE:
Substantial overloading will turn off the circuit breaker.
Exceeding the time limit for maximum power operation or
slightly overloading the generator may not turn off the
circuit breaker or circuit protector, but will shorten the
service life of the generator.
Limit operation requiring maximum power to one hour.
Maximum power is as follows:
EG2250A: 2.2 kW
EG2850A: 2.8 kW
EG4550A: 4.5 kW
EG5550A: 5.5 kW
EG6050A: 6.0 kW
For continuous operation, do not exceed the rated power.
Rated power is as follows:
EG2250A: 2.0 kW
EG2850A: 2.6 kW
EG4550A: 4.0 kW
EG5550A: 5.0 kW
EG6050A: 5.5 kW
The total power requirements (VA) of all appliances
connected to the generator must be considered. Rating
information for appliances and power tools are usually
listed near the model number or serial number.
AC Operation (Fig. 12)
1. Start the engine.
2. Turn on the AC circuit breaker.
3. Plug in the appliance.
NOTICE:
Before connecting any appliance to the generator, make
sure they are in good working condition. If an appliance
begins to operate in an abnormal manner, becomes slow,
or stops suddenly, turn off the ignition switch lever
immediately. Then disconnect the appliance and check for
signs of malfunction.
Most motorized appliances require more than their rated
power for startup.
Do not exceed the current limit specified for any one
receptacle. If an overloaded circuit causes the AC circuit
breaker or AC circuit protector to turn off, reduce the
9
