BEFORE STARTING ENGINE
Always check engine oil level
before every start. Running
engine low of oil or out of oil could result in
serious damage to the engine.
Adding Engine Oil
Your generator has been shipped without oil in the
engine. Begin by removing the oil dipstick and plug.
Start pouring the oil in slowly.
The engine will hold approximately 48 ounces/1.4 liters
of oil.
To check oil:
Place engine in a level position. Clean around oil
fill and dipstick.
Remove dipstick and wipe clean with cloth.
Push dipstick back in and remove to check oil.
Keep oil level at FULL line on dipstick.
To add oil:
Remove oil fill cap.
Pour oil slowly and fill to FULL line on dipstick. Do
not overfill.
An extension cord that is hot
to the touch is overloaded.
Repair or replace damaged extension cords
immediately.
Connecting Generator To Main Electrical
Supply
Potential hazards exist when a electrical generator is
connected to the main electrical supply coming into
the house. It is at that point that the generator could
feed back into the utility company’s system causing
possible electrocution of workers who are repairing
electrical lines. To avoid back feeding of electricity into
utility systems, a double-throw transfer switch
should be installed between the generator and utility
power. This device should be installed by a licensed
electrician and in compliance with all local electrical
codes.
NOTE: When installing a Double-Throw Transfer
Switch, a minimum of 10 gauge wiring must be used.
Gasoline
To add gasoline:
Remove gas cap.
Add unleaded gasoline, slowly, to fuel tank.
Use clean, fresh, regular unleaded gasoline with a
minimum of 85 octane. Use unleaded fuel only. Do not
use gasoline which contains Methanol. Never mix oil
with gasoline.
Never fill fuel tank com-
pletely. Fill tank to 1/2" below the bottom of the
filler neck to provide space for fuel expansion.
Wipe any fuel spillage from engine and equip-
ment before starting engine.
Do not overfill.
Replace gas cap.
Never fill fuel tank indoors.
Never fill fuel tank when engine is running or
hot. Do not smoke when filling fuel tank.
Turn engine OFF and let
engine cool at least 2 minutes before removing
gas cap.
