Connection
WARNING
Before the generator can be connected to a building’s electrical system, a licensed electrician must
install an isolation (transfer) switch in the building’s main fuse box. The switch is the connection
point for generator power and allows selection of
generator or main line power to the building. This
will prevent the generator from charging the main
power line (backfeeding) when the main power
supply has failed or has been turned off for line
repair. Backfeeding can electrocute or injure line
maintenance personnel. Also, generator and building electrical system damage can occur when normal operating power returns if unit is used without
an isolation switch.
AE00086
Extension cord notes
Extension cords should be protected by a tough flexible rubber sheath (IEC 245) or the equivalent to withstand mechanical stresses.

NOTICE
9 Do not overload. The total load of all electrical appliances must not exceed
the supply range of the generator. Overloading will damage the generator.
9 When supplying precision equipment, electronic controllers, PCs, electronic
computers, microcomputer-based equipment or battery chargers, keep the
generator a sufficient distance away to prevent electrical interference from
the engine. Also ensure that electrical noise from the engine does not interfere with any other electrical devices located near the generator.
9 If the generator is to supply medical equipment, advice should first be
obtained from the manufacturer, a medical professional or hospital.
9 Some electrical appliances or general-purpose electric motors have high starting
currents, and cannot therefore be used, even if they lie within the supply ranges
given in the above table. Consult the equipment manufacturer for further advice.

Perform the following steps to protect the cylinder, piston ring, etc. from corrosion.
1. Remove the spark plug, pour about one tablespoon of engine oil (See page 15) into the spark
plug hole and install the spark plug. Recoil start
the engine by turning over several times (with ignition off) to coat the cylinder walls with oil.
2. Pull the recoil starter until you feel compression.
Then stop pulling. (This prevents the cylinder and
valves from rusting).
3. Clean exterior of the generator and apply a rust
inhibitor.
4. Store the generator in a dry, well-ventilated place,
with the cover placed over it.
5. The generator must remain in a vertical position
when stored, carried or operated.
