• If the appliance, tool or motor does not give watt-
age, multiply volts times ampere rating to deter-
mine watts (volts x amps = watts).
• Some electric motors, such as induction types,
require about three times more watts of power for
starting than for running. This power surge lasts
only a few seconds. To allow for high starting watt-
age when selecting electrical devices to connect to
the generator, proceed as follows:
1. Figure the watts needed to start the largest motor.
2. Add to that figure the running watts of all other con-
nected loads.
3. See Subsection 3.5 — Wattage Reference Guide
for help in determining how many items the gener-
ator can operate at one time.
NOTE: All figures are approximate. See data label on
appliance for actual wattage requirements.

3.6 — Before Starting Generator
Add engine oil and gasoline to the generator before oper-
ation. Proceed as follows:
3.6.1— Add Engine Oil
All oil should meet minimum American Petroleum Insti-
tute (API) Service Class SJ, SL or better. Use no special
additives. Select the oil's viscosity grade according to the
expected operating temperature.
Per the engine manufacturer's recommendation, after the
use of the initial break-in oil, subsequent oil changes may
use synthetic oil. See Figure 3-7.
• SAE 30 above 32° F (0° C)
• 10W-30 between 40° F and -10° F (4° C and -23°
C)
• Synthetic 5W-30 for all temperature ranges
