MAINTENANCE
BATTERY REPLACEMENT
The battery (part no. DF475-041) shipped with the generator has been fully charged. The battery will receive charge
when the engine is running. Remember to run the generator once a month for 20-30 minutes to charge the battery.
A charged battery will allow you to start the generator using the electric start switch during your next time of need.
If the battery is out of charge, you can still manually start the generator using the recoil start with LPG as your fuel
source.
IMPORTANT:
If the generator is not used for a long period, it is recommended to disconnect the positive battery
cable from the battery to protect the battery from losing charge. After disconnecting the cable, cover the free end
with an insulator such as electrical tape. You may can also connect the battery to an automatic trickle charger to
keep the battery charged.
To reinstall/replace the battery:
1. Remove the wheel next to the battery to provide room sufficient room.
2. Disconnect the negative (-) battery terminal first (black wire).
3. Disconnect the positive (+) battery terminal second (red wire).
4. To install a new battery, install the hold down bracket, insert the threaded rod and tighten with M6 nuts.
5. Connect the positive (+) battery terminal (red wire) first. Slide rubber boot over connection hardware.
6. Connect the negative (-) battery terminal (black wire) second.
7. Slide rubber boot over connection hardware.

NOTE: Always recycle used batteries in accordance with local laws and regulations. Contact your local solid waste
collection site or recycling facility to obtain information on local recycling processes.
DRAINING THE FUEL TANK
Drain and clean the fuel tank each year, or before storing the generator for longer than two months.
To drain the fuel tank:
1. Prepare an approved gasoline-storage container to collect the drained fuel. Place it near the fuel valve.
2. Turn the fuel valve to the OFF position.
3. Locate the fuel line between the fuel valve and back of control panel. Disconnect the fuel line from the fuel valve.
NOTE: A small amount of fuel may leak from the fuel line during removal.
4. Place a funnel below the fuel valve opening, and direct the other end of the funnel over the prepared container.
Turn the fuel valve to ON to start draining the fuel from the fuel valve opening.
5. Once the fuel is drained, shut OFF the fuel valve.
6. Start and run the engine until the fuel runs out.
