DIGITAL DISPLAY
See Figure 11.
Press and release the mode button to cycle through the
following displays:
Voltage (V) displays the operating voltage of the generator.
Frequency (F) displays the frequency in hertz at which the
generator is running.
The Run/Maintenance Timer displays the amount of time
the generator has run since being started. This timer resets
each time the generator is shut off.
When a cumulative run time of 25 hours has been reached,
P25 will display on the meter as a reminder to change the
engine lubricant after the initial 25 hours of run time.
When a cumulative time of 50 hours is reached, P50 will
display on the meter to remind you to clean the air filter.
When a cumulative time of 100 hours is reached, P100 will
display on the meter to remind you to change/clean the fuel
filter, clean the air filter, and change the engine lubricant.
ELECTRIC START
This generator model is provided with both electric start and
recoil start capabilities. Avoid prolonged cranking, as it can
damage the engine.
The battery provided is a nominal 12 volt sealed rechargeable
lead-acid battery and can be operated in any position without
leakage. It complies with non-spillable battery regulations.
NOTE: Brand new generators are shipped with the battery
disconnected. The starter cable on the generator must be
connected to the battery harness and the battery must be
charged before the electric start feature of the generator
will work.
For initial battery connection, see Connecting/Disconnecting
Battery.
STARTING THE ENGINE
See Figures 12 - 14.
NOTICE:
On a level surface with the engine off, check the lubricant
level before each use of the generator.
NOTE: If location of generator is not level, the unit may not
start or may shut down during operation.
This generator is equipped with electronic fuel injection.
Starting the generator will require a brief wait to allow the
fuel to travel from the tank.
 Unplug all loads from the generator.
 Turn the fuel valve to the ON ( I ) position.
 To start the engine using the electric start:
OPERATION
Put the engine switch in the ON position.
1
Wait 30 seconds to allow fuel to travel through the
2

NOTE: The engine will not start until the fuel has
reached the fuel injector and the proper operating
pressure is acheived.
Slide down and hold the lock button while pushing
3
the engine switch to the START position. Release the
switch when the engine starts.
NOTE: The battery may require charging before the gen-
erator can be started using either the engine switch or the
recoil starter. Once the generator is started, the battery
will charge as the unit runs. If the engine switch will not
start the unit once the battery has been fully charged,
check the circuit protector fuse and replace if needed fol-
lowing instructions in Changing Engine Battery Charge
Circuit Fuse in the Maintenance section of this manual.
 To start the engine using the recoil starter:
Put the engine switch in the ON position.
1
Wait 30 seconds to allow fuel to travel through the
2
line.
NOTE: The engine will not start until the fuel has
reached the fuel injector and the proper operating
pressure is acheived.
Pull the recoil starter grip until the engine runs.
