grounding provides a path of least resistance for electric current to reduce the risk of electric shock.
Improper connection of the equipment-
grounding conductor can result in a risk of electrocution. Check with a qualified electrician or service person if you
are in doubt as to whether the unit is properly grounded.
The wing nut and ground terminal on the frame must always be used to connect the generator to a suitable ground source. The ground path should be made with #8 size wire. Connect the terminal of the ground wire between the two star washers and wing nut then tighten the wing nut fully. Connect the other end of the wire securely to a suitable ground source.
The National Electric Code contains several practical ways in which to establish a good ground source. Examples given below illustrate a few of the ways in which a good ground source may be established.
A metal underground water pipe in direct contact with the earth for at least 10 feet can be used as a grounding source. If an pipe is unavailable, an 8 foot length of pipe or rod may be used as the ground source. The pipe should be 3/4 inch trade size or larger and the outer surface must be noncorrosive.
If a steel or iron rod is used it should be at least 5/8 inch diameter and if a nonferrous rod is used it should be at least 1/2 inch diameter and be listed as material for grounding. Drive the rod or pipe to a depth of 8 feet. If a rock bottom is encountered less than
4 feet down, bury the rod or pipe in a trench. All electrical tools and appliances operated from this generator, must be
properly grounded by use of a third wire or be “Double Insulated”.
It is recommended to:
1.Use electrical devices with 3 prong power cords.
2.Use an extension cord with a 3 hole receptacle and a 3 prong plug at the opposite ends to ensure continuity of the ground protection from the generator to appliance.
We strongly recommend that all applicable federal, state and local regulations relating to grounding specifications be checked and followed.
LINE TRANSFER SWITCH
If this generator is used for standby service, it must have a transfer switch between the utility power service and the generator. The transfer switch not only prevents the utility power form feeding into the generator, but is also prevents the generator form feeding out into the utility company’s lines. This is intended to protect the serviceman who may be working on a damaged line.
THIS INSTALLATION MUST BE DONE BY A LICENSED ELECTRICIAN AND ALL LOCAL CODES MUST BE FOLLOWED.
engine oil
Use oil viscosity based on the expected air temperature range during the period between oil changes.
Use a high quality detergent oil with API classifications of SJ or higher.
Check oil level before each operation and ensure that it is maintained.
THIS ENGINE CRANKCASE IS NOT
FILLED WITH OIL AT THE FACTORY, SO BE SURE TO FILL IT BEFORE OPERATING THE ENGINE.
NOTE: These engines are equipped with a “Low Oil”
Pre-Operation
FUELING
To fill with oil:
1.Level the engine to ensure accurate inspection and to prevent overfilling.
2.Unscrew the oil gauge, wipe the dipstick dry. Reinsert the oil gauge back into the oil fill gauge opening. Remove the oil gauge and check the oil level.
3.The oil level should be between the full and low marks on the dipstick.
NOTE: When checking the oil be sure the engine is level.
4.Fill with oil as required through the oil fill gauge opening.
5.Replace the oil gauge and screw in firmly. 6.Wipe up any spilled oil.
EXPLOSIVE FUEL! GASOLINE IS
EXTREMELY FLAMMABLE AND ITS VAPORS CAN EXPLODE IF IGNITED.
STORE GASOLINE ONLY IN APPROVED CONTAINERS, IN WELL VENTILATED, UNOCCUPIED BUILDINGS AND AWAY FROM SPARKS OR FLAMES.
DO NOT FILL THE FUEL TANK WHILE THE ENGINE IS HOT OR RUNNING, SINCE SPILLED FUEL COULD IGNITE IF IT COMES IN CONTACT WITH HOT PARTS OR SPARKS FROM IGNITION. DO NOT START THE ENGINE NEAR SPILLED FUEL.
NEVER USE GASOLINE AS A CLEANING AGENT.
DO NOT OVERFILL THE FUEL TANK, LEAVE
ROOM FOR THE FUEL TO EXPAND.
General Recommendations
•Purchase gasoline in small quantities and store in clean, approved containers.
