PREPARATION
STEP 3 - GROUND THE GENERATOR
To reduce the risk of electric shock and to maximize safety,
the generator should be properly grounded.
1. Attach one end of the grounding wire to the grounding
nut (Fig. 7 - 1). Tighten the nut to secure the grounding
wire.
2. Connect the other end of the grounding wire to a copper,
brass, or steel-grounding rod that is driven into the earth.
HIGH ALTITUDE OPERATION ABOVE 3000 FEET
The fuel system on this generator may be affected by opera-
tion at high altitudes. Proper operation can be ensured by
installing an altitude kit at altitudes higher than 3000 feet
above sea level. At elevations above 9800 feet, the engine
may experience a decrease in performance, even with the
proper altitude kit. Operating this generator without said kit
may increase the engine’s emissions and decrease both fuel
economy and performance.
This kit should be installed by a qualified mechanic. You can
order the kit at wenproducts.com by searching part number
DF680iX-HA39. Refer to the instructions included with your
altitude kit for more information about installation.
WARNING! Failure to properly ground the generator
increases your risk of electric shock.
WARNING! To prevent serious injury from fire,
follow the kit installation procedures in a well-ventilated
area away from ignition sources. If the engine is hot from
use, shut the engine off and wait for it to cool before
proceeding. Do not smoke near the generator. Warranty
will be void if adjustments are not made for high altitude
use.
CAUTION! UNINSTALL the high altitude kit when
operating at altitudes below 3000 feet.
NOTE: Grounding wire and grounding rods are not
included with the generator. A generally acceptable
grounding wire is a No. 12 AWG (American Wire
Gauge) stranded copper wire. Grounding codes can
vary by location. Contact a local electrician to check the
area codes.

STEP 4 - CONNECT THE BATTERY
WARNING! Battery gives off explosive hy-
drogen gas.
• Keep the battery away from sparks, flames, and
cigarettes.
• Do not connect or disconnect the battery while
the generator is running.
• Service or use the battery only in well ventilated
areas.
WARNING! Battery contains sulfuric acid.
Battery acid is poisonous. Tilting the generator
with the battery installed can cause battery acid
to spill.
• Wear protective clothing and eye wear when
servicing the battery.
• Keep out of the reach of children.
• Do not tilt the generator with the battery in-
stalled.
• If battery acid gets on your skin, wash with wa-
ter immediately.
• If battery acid gets in your eyes, flush with wa-
ter for at least 15 minutes and call a doctor im-
mediately.
If battery acid is swallowed, call a doctor imme-
diately. Drink a large amount of water or milk.
Then drink the milk of magnesia or vegetable oil.
WARNING! Use only genuine WEN batteries
with your generator (part no. DF475-041). Use
of other batteries may induce premature product
failure and could pose a safety risk.
