an indication of a problem. As LPG vaporizes and
travels from the tank to the generator engine it
expands. The amount of frost that forms can be
affected by the size of the cylinder, the amount
of fuel being used, the humidity of the air and other
operating conditions. In unusual situations this
frost may eventually restrict the flow of LPG gas
to the generator resulting in deteriorating
performance. For example, if the tank temperature
is reduced to a very low level then the rate at which
the LPG vaporizes is also reduced and may not
provide sufficient fuel flow to the engine. This is
not an indication of a problem with the generator
but only a problem with the flow of gas from the
LPG cylinder. If generator performance seems
to be deteriorating at the same time that ice
formation is observed on tank valve, hose or
regulator then some actions may be taken to
eliminate this symptom. In these rare situations
it can be helpful to reduce or eliminate the cold
fuel system effects by doing one of the following:
• Exchanging fuel tanks to allow the first tank

to warm up, repeating as necessary
• Placing the LPG cylinder at the end of the

generator near the handle, where engine fan
air flows out from the generator. This air is
slightly heated by flowing over the engine.

General Recommendations
Regular maintenance will improve the performance and extend the life of the generator. See any
authorized dealer for service.
The generator's warranty does not cover items that have been subjected to operator abuse or
negligence. To receive full value from the warranty, the operator must maintain the generator as
instructed in this manual.
Some adjustments will need to be made periodically to properly maintain your generator.
All service and adjustments should be made at least once each season. Follow the requirements
in the Maintenanc Shedule chart above.
Notice Once a year you should clean or replace the spark plug and replace the air filter. New
spark plugs and clean air filter assure proper fuel-air mixture and help your engine run better
and last longer.

Battery Charging & Maintenance
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.
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.

You are responsible for presenting your SORE or engine powered equipment to a FIRMAN distribution or service center as soon
as a problem exists. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days. If you have
a question regarding your warranty coverage, you should contact FIRMAN at 1-844-347-6261 or firmangenerators@sumec-na.com.
GENERAL EMISSIONS WARRANTY COVERAGE
This emission control system is warranted for three years. The warranty period begins on the date the engine or equipment is delivered
to an ultimate purchaser. FIRMAN warrants to the ultimate purchaser and each subsequent purchaser that the engine is:
Designed, built, and equipped so as to conform with all applicable regulations adopted by the Air Resources Board and US EPA;
and Free from defects in materials and workmanship that cause the failure of a warranted part to be identical in all material
respects to the part as described in the engine manufacturers application for certification.
The warranty on emissions-related parts is as follows:
(1) Any warranted part that is not scheduled for replacement as required maintenance in the owner's manual supplied, is
warranted for the warranty period stated above. If any such part fails during the period of warranty coverage, the part will be
repaired or replaced by FIRMAN at no charge to the owner. Any such part repaired or replaced under the warranty will be
warranted for the remaining warranty period.
(2) Any warranted part that is scheduled only for regular inspection in the owner's manual supplied, is warranted for the warranty
period stated above. Any such part repaired or replaced under warranty will be warranted for the remaining warranty period.
(3) Any warranted part that is scheduled for replacement as required maintenance in the owner's manual supplied, is warranted
for the period of time prior to the first scheduled replacement point for that part. If the part fails prior to the first scheduled
replacement, the part will be repaired or replaced by FIRMAN at no charge to the owner. Any such part repaired or replaced
under warranty will be warranted for the remainder of the period prior to the first scheduled replacement point for the part.
(4) Repair or replacement of any warranted part under the warranty must be performed at no charge to the owner at a warranty
station.
(5) Notwithstanding the provisions of Subsection (4) above, warranty services or repairs must be provided by FIRMAN that are
franchised to service the subject engines.
(6) The owner must not be charged for diagnostic labor that leads to the determination that a warranted part is in fact defective,
provided that such diagnostic work is performed at a warranty station.
(7) FIRMAN is liable for damages to other engine components proximately caused by a failure under warranty of any warranted
part.
(8) Throughout the emissions warranty period defined in Subsection (b)(2), FIRMAN will maintain a supply of warranted parts
sufficient to meet the expected demand for such parts.
(9) Any replacement part may be used in the performance of any warranty maintenance or repairs and must be provided without
charge to the owner. Such use will not reduce the warranty obligations of the manufacturer.
(10) Add-on or modified parts that are not exempted by the Air Resources Board may not be used. The use of any non-exempted
add-on or modified parts by the ultimate purchaser will be grounds for disallowing a warranty claim.
The manufacturer will not be liable to warrant failures of warranted parts caused by the use of a non-exempted add-on or modified
part.
