Do not operate with the battery disconnected
or if any fuse is blown at the Univolt as some
components such as light bulbs can be dam¬
aged. If the battery charger is operated under
these conditions, the 3 amp fuse (E) will
blow, preventing the generator from charging.
Although the motor will continue to run, the
generator will not charge the battery. Per¬
iodically check 3 amp fuse to make sure
generator is charging properly.
If the engine doesn't start initially after using
the following instructions, remove the spark
plug, clean, dry thoroughly and re-install.
Smoky exhaust, due to oil in the cylinder
might appear on initial start and is normal.
Electric Starting
1. Turn the adjustable timer on the remove
control to the desired duration of oper¬
ation.
2. Push the START BUTTON on the remote
control to crank the engine.
If the timer is set to zero, the unit won't
start regardless how long cranking is con¬
tinued.
Note: For easier starting in cooler tempera¬
tures, the choke can be manually closed
while the engine cranks — helps draw fuel
through the fuel regulator. The choke is
located on engine carburetor.
Manual Starting
1. Turn the adjustable timer on the remote
control to the desired duration of opera¬
tion.
2. Push in the fuel solenoid button (A).
3. Pull the start rope (D) with a fast, steady
pull to crank the engine.
4. As soon as the engine is running, release
the fuel solenoid button. Generator cur¬
rent now holds the fuel solenoid open.
Battery Charging
The charge rate of the TL battery charger is
factory set for battery charging. A small lamp
marked "GENERATING" lights once the unit
is running and charging properly. Operation
time ranges to 3 hours and is set by the
adjustable timer on the remote control.
Light loads, appliances or fixtures, can be
operated from the battery while the unit is
running. If the load should ever exceed
generator capacity, the generator field will
collapse and prevent any damage. As an
indication the small "GENERATING" lamp
on the remote control will fail to light when
the generator field collapses. Remove some
load for proper operation.

As a general guide, a 105 ampere-hour battery
requires approximately 3 hours charging if the
battery is in a low charge condition. For a
more exact determination, use a hydrometer.
Stopping
Stopping occurs automatically when the ad¬
justable timer on the remote control returns
to zero. If you wish to shut down the unit
before automatic shutdown, manually turn
the pointer on the timer back to zero.
High Temperatures
1. See that nothing obstructs air flow to and
from the unit.
2. Keep cooling fins clean.
Low Temperatures
1. Use correct SAE oil for temperature condi¬
tions. Change oil only when engine is
warm.
2. Keep batteries in a well charged condition.
3. Partially restrict cool air flow if necessary,
but use care to avoid overheating.
Extremely Dusty or Dirty Conditions
1. Keep unit clean. Keep cooling system
clean.
2. Service air cleaner as frequently as re¬
quired.
3. Change crankcase oil more often than
shown in Maintenance and Service.
4. Keep governor linkage clean.
