SERVICE AND STORAGE

Infrequent Service

If the unit is used infrequently, difficult starting 
may result. To eliminate hard starting, follow 
these instructions:
1. Run the generator at least 30 minutes every 
    month.
2. Run the generator, then close the fuel shut-off 
    valve and allow the unit to run until the engine 
    stops.
3. Move the fuel selector to the "OFF" position.

Long Term Storage

When the generator set is not being operated 
or is being stored more than one month, follow 
these instructions:

NEVER USE WATER TO CLEAN GENERATOR. 

Pull starter handle until resistance is felt, leaving 
handle in that position. 
Store generator in a well ventilated, low humidity 
area.

NOTE

: We recommend always using a fuel 

stabilizer. A fuel stabilizer will minimize the 
formulation of fuel gum deposits during 
storage. The fuel stabilizer can be added to 
the gasoline in the fuel tank, or into the 
gasoline in a storage container.

WARNING

Generator exhaust contains odorless and
colorless carbon monoxide gas.

To  avoid  accidental  or  unintended  ignition  of 
your  generator  during  periods  of  storage,  the 
following  precautions  should  be  followed:
When storing the generator for short or extended 
periods  of  time  make  sure  that  the  fuel  selector 
switch  is  in  the  “OFF”  position  and  the  battery 
leads have been disconnected from the battery.

The battery powers up the starter motor and  the control 
module in this generator

. This product is equipped with 

an  automatic  battery  charging  circuit.  The  battery  will 
receive  charging  voltage  when  the  engine  is  running. 
The  battery  will  maintain  a  proper  charge  if  the  unit  is 
used  on  a  regular  basis  (about  once  every  two  weeks). 
If it is used less frequently, the battery should be connected 
to a trickle charger (not included) or battery maintainer (not
included)  to  keep  the  battery  properly  charged.  If  the
battery  is  not  able  to  start  the  engine,  it  can  be  started
manually  only  on  “

GAS

”  position  by  pulling  the  engine 

recoil  cord.  If  the  battery  voltage  is  extremely  low,  the 
charging circuit may not be able to re-charge the battery. 
In this case, the battery must be connected to a standard 
automotive  style  battery  charger  for  re-charging  before 
it can be used.
