Machine Safety Decals

The MQ GA-2.9R portable generator is equipped with a number of safety decals (Figure 2). These decals are provided for operator safety and maintenance information. The illustration below shows these decals as they appear on the machine. Should any of these decals become unreadable, replacements can be obtained from your dealer.

MQ GA-2.9R — GENERAL INFORMATION

MQ GA-2.9R Familarization

General Inspection Prior to Operation

This generator has been thoroughly inspected and accepted prior to shipment from the factory. However, be sure to check for damaged parts or components, or loose nuts and bolts, which could have become disloged in transit.

The

MQ Model GA-2.9R

portable lightweight power source for 60 Hz (single-phase) vibrators, lighting facilities, power tools, submersible pumps and other industrial and construction machinery.

This generator is powered by a 5.7 HP ROBIN air-cooled gasoline engine. The alternator, a brushless revolving-field type, is permanently aligned to the engine through rigid coupling.

The generator is mounted on rubber vibration isolators that have a steel base backplate which is attached to the protective steel pipe carrying frame. The protective carrying frame is made of steel tubing and fully wraps around the generator to protect against damage.

This portable generator is supplied with a electrical

panel

. The control panel includes items as listed below.

Control Panel

The generator control panel has the following componets:

■

NEMA 5-20R, GFCI duplex receptacle, (120V, 20 amps)

■

NEMA L5-20R, twist-lock receptacle, (120V, 20 amps)

generator has been designed as a

control

Excitation System

The MQ GA-2.9R generator uses a magnet attached to a flywheel to produce AC voltage from a lamp coil beneath the flywheel. As the magnet passes the coil it produces approximately 19-22 AC volts.

This voltage (19-22 VAC) is then sent to the control box that contains three rectifying diodes:

Excitation (diode 1)

Battery (diode 2)

Slow Down (diode 3)

The AC voltage will pass through the excitation diode that converts the voltage to DC power.

This DC power is then sent to the excitation windings housed within the main windings commonly called the "stator".

This voltage is then transferred into the rotor through induction. The rotor contains two diodes within it which rectify the DC voltage and send it out through the main windings, as AC voltage.

MQ GA-2.9R— LOAD APPLICATION

Single Phase Load

Always be sure to check the nameplate on the generator and equipment to insure the wattage, amperage and frequency requirements are satisfactorily supplied by the generator for operating the equipment.

Generally, the wattage listed on the nameplate of the equipment is its rated output. Equipment may require 130— 150% more wattage than the rating on the nameplate, as the wattage is influenced by the efficiency, power factor and starting system of the equipment.

If wattage is not given on the equipment's

NOTE

WATTS = VOLTAGE x AMPERAGE The power factor of this generator is 1.0 See Table 2 below

when connecting loads.

name plate, approximate wattage may be determined by multiplying nameplate voltage by the nameplate amperage.

To determine the running wattage for your load, multiply the running wattage as indicated by steps 1, 2, and 3 below:

1. INCANDESCENT LOADS Lights, heaters and similar appliances. Total the running wattage and multiply by 1. Example: 29 light bulbs @ 100W each = 2.9 KW use a 3 KW generator.

2. SMALL MOTORS Drills and other small power tools. Total the running wattage and multiply by 2. Example: A 1 inch drill runs at 1 KW use a 2 KW generator.

3. LARGE MOTORS Submersible pumps, table saws etc. Total the running wattage and multiply by 3. Example: A conveyor belt runs at 8 KW use a 24 KW generator.

2. GFCI Receptacle – This receptacle will provide 120V at all times.

3. AC-Voltmeter – This voltmeter indicates (with a mark) the rated 60 Hz, single phase output voltage. In addition the voltmeter can also be used as a diagnostic tool. If the voltmeter indicator (needle) is below the rated voltage, engine problems may exist (low/high RPM's). To prevent damage to the generator or power tools turn the generator OFF and consult your authorized MQ service dealer.

4. Main Circuit Breaker – This single-pole 22 amp breaker protects the generator from short circuiting or overloading. When starting the generator placed in the "OFF" position.

5. Ground – This ground connection point should be connect to a good earth ground (ground rod).

NOTE

Make sure the generator is placed on level ground. Placing the generator on level ground will ensure that the low oil sensor will function properly.

16. Recoil Starter (Pull Rope) – Used for manual-starting of the engine. Pull the starter grip until resistance is felt, then pull briskly and smoothly.

17. Engine – This generator uses a 5.1 HP ROBIN aircooled, 4-stroke , single cylinder, overhead camshaft gasoline engine. Engine uses unleaded fuel.

18. Air Cleaner – Prevents dirt and other debris from entering the fuel system. Remove wing-nut on top of air filter cannister to gain access to filter element. NEVER run the engine without an air cleaner.

DANGERDANGER

Adding fuel to the tank should be done only when the engine is stopped and has had an opportunity to cool down. In the event of a fuel spill, DO NOT attempt to start the engine until the fuel residue has been completely wiped up, and the area surrounding the engine is dry. If generator is placed in a truck bed with a plastic liner, REMOVE generator from truck bed and place on ground (Figure 4) to refuel. This possibility exist of

MQ GA-2.9R — INSTALLATION

Outdoor Installation

Install the generator in a area that is free of

bystanders

generator is on secure level ground so that it cannot slide or shift around. Also install the generator in a manner so that the exhaust will not be discharged in the direction of nearby homes.

The installation site must be relatively free from moisture and dust. All electrical equipment should be protected from excessive moisture. Failure to do will result in deterioration of the insulation and will result in short circuits and grounding.

Foreign materials such as dust, sand, lint and abrasive materials have a tendency to cause excessive wear to engine and alternator parts.

Pay close attention to ventilation when operating the generator inside tunnels and caves. The engine exhaust contains noxious elements.

Indoor Installation

Exhaust gases from gasoline engines are extremely poisonous. Whenever an engine is installed indoors the exhaust fumes must be vented to the outside. The engine should be installed at least two feet from any outside wall. Using an exhaust pipe which is too long or too small can cause excessive back pressure which will cause the engine to heat excessively and possibly burn the valves.

Eliminate the danger of deadly carbon monoxide gas. Remember that exhaust fumes from any gasoline engine are very poisonous if discharged in a closed room, but harmless if allowed to mix with the outside air. If the generator is installed indoors, you must make provisions for venting the engine exhaust to the outside of the building.

Generator Grounding

To guard against electrical shock and possible damage to the equipment, it is important to provide a good EARTH ground. Always use the ground terminal on the generator to ground the generator.

Article 250 (Grounding) of the National Electrical Code (NEC) provides guide lines for proper grounding and specifies that the cable ground shall be connected to the grounding system of the building as close to the point of cable entry as practical.

Mounting

The generator should always be mounted on a flat level surface to isolate vibration of the generator when it is running. DO NOT place the generator on slopes, the possibility exists that the generator could slide.

NEC articles 250-64(b) and 250-66 set the following grounding requirements:

1. Use one of the following wire types to connect the generator to earth ground.

a. Copper - 10 AWG (5.3 mm2) or larger. b. Aluminum - 8 AWG (8.4 mm2) or larger.

2. When grounding the generator (Figure 3) connect the ground cable between the lock washer and the nut on the generator and tighten the nut fully. Connect the other end of the ground cable to earth ground.

3. NEC article 250-52(c) specifies that the earth ground rod should be buried a minimum of 8 ft. into the ground.
