2. Connect the grounding rod cable to the grounding
terminal.
E
D
Selecting Cable
• Select a cable (F) with sufficient diameter by
considering the permissible current on the cable
and the distance from the generator to the load (G).
• If the current flowing to the load exceeds the
permissible current of the cable, resultant
overheating may burn the cable. Similarly, if the
cable is too small in thickness to the length, the
input voltage to the load will fall to cause the load
input power to drop, as a result, the performance of
the machine cannot be displayed.
F
G
• Below is a simplified three-phase three-wire formula
to seek voltage drop or cross-sectional area of
the cable from cable length and working current.
Select such a cable length and thickness so that the
voltage drop will remain less than 5%.

plug-in carbon monoxide alarms with battery back-up
according to the manufacturer’s instructions. Smoke
alarms cannot detect carbon monoxide gas.
• DO NOT run this product inside buildings, garages,
tunnels, or other partially-enclosed spaces, even
if using fans for ventilation. Carbon monoxide can
quickly build up in these spaces and can linger for
hours, even after this product has shut off.
• ALWAYS place this product downwind and point the
engine exhaust away from occupied spaces.
If you start to feel sick, dizzy, or weak while using this
product, get to fresh air RIGHT AWAY. See a doctor.
You may have carbon monoxide poisoning.
Oil Recommendations
Engine Oil
We recommend the use of CJ-4 class engine oil or
superior class for best performance. Using poor quality
engine oil may shorten the life of the engine.
Outdoor temperatures determine the proper oil viscosity
for the engine.
Use the chart to select the best viscosity for the outdoor
temperature range expected.
NOTICE When two or more different brands of oil are
mixed, its performance can be deteriorated. When it
is expected to be used for a long period at light load
(less than 20% load), it’s better to replace the oil with
suitable oil.

belt may slip and will cause early breakage or damage to
the belt.
1. Visually check the belt for any cracks, wear, and other
defect. Replace if needed.
2. Depress the middle of the belt with a finger. Belt
deflection should be between 0.24 - 0.31” (6 - 8mm)
(F).
If adjustment is needed:
1. Loosen the alternator mounting bolt. Adjust until belt
deflection is 0.24 - 0.31” (6 - 8mm) when pressing with
a finger. Tighten securely.
2. Wipe any grease, oil, coolant, etc. from belt.

Clean Control Panel
Open control panel and check each breaker, terminal
plate and controller for any dust, sand and dirt
accumulated. Clean with compressed air.
Unit Operation
WARNING
• Keep the door shut and locked when machine is in
operation.
• If opening the door is necessary, be careful not to
touch rotating or hot parts. Burns or serious injury
could result.
NOTICE Be sure to let unit warm up after starting for
smooth operation of the engine and the generator. Do
not operate the engine at full load immediately after
starting. This will shorten the equipment life.

once the start signal is sensed. See Function.
Function
• When the start signal activates in stand-by mode,
it starts the unit. (This includes preheating.)
• When the stop signal activates, the unit continues
to operate for a cool-down phase, then the unit
stops and is placed again in stand-by mode.
Starting Action
• The unit will attempt to start over three 10-second
intervals, with an 8-second break (including
preheating) between attempts. If after the third
attempt the unit will not start, an indicator light
will light, indicating the problem. See Meters and
Indicator Lights during Operation; see also
Troubleshooting.
• If the OVERCRANK indicator light turns on,
immediately press the emergency stop button.

Meters and Indicator Lights during Operation
During normal operation, each indication of
instruments is shown in the table below. Refer to the
table for daily checks.
NOTE: The values marked * vary with location of the
voltage selector switch.
• Be sure to frequently check meters and indicators
for proper operation, or any machine water, oil,
fuel leaks, etc.
• The above table gives standard values. They may
vary slightly depending on operating conditions
and other factors.
• In single-phase load operation, check the current
of L1, L2, and L3 phase with the ammeter, by
turning the ammeter change-over switch.
Each current should be balanced if unbalanced.
Change load connections so the current of L1,
L2, and L3 is equally balanced. Make sure that
the current of each phase does not exceed the
rated one.
• When the voltage selector switch is in the single-
phase 240/120V position, place the ammeter
change-over switch to the L1 or L3 position to
read the output.
Panel Light
• The instruments are provided with illumination.
Switch the panel light to ON.
• When illumination is not necessary, turn the light
OFF to conserve lamp life.
