V. Exhaust Control System
With the engine running carbon monoxide, nitrogen oxide and hydrocarbons are produced. Carbon monoxide is a toxic gas
and in certain conditions, nitrogen oxide and hydrocarbon will react chemically with each other to make smoke, so proper
maintenance to control these dangers is very important.
To keep the exhaust of your engine within the standard exhaust emission, pay attention to the following:
1. Maintenance
Maintain the engine periodically in accordance with the maintenance schedule in the “Maintenance” section. The
maintenance schedule is based on normal use in normal conditions. If using under heavy load, dusty or wet circumstances or
in high temperature, service of the engine should be done more often.
2. Replacing Parts
To ensure the best quality and reliability, use only genuine DR Power replacement parts.
3. Tampering and Altering
Tampering with or altering the emissions control system may increase emissions beyond the legal limit. Do not remove or
alter and part of the intake, fuel, or exhaust systems. Do not alter or remove the governor linkage or speed adjusting
mechanism. Doing so will cause the engine to operate outside of its design parameters and will result in engine damage.
2. Problems affecting exhaust emissions
Difficult starting or difficult stopping.
Unstable idling speed.
Exhausting of black smoke or consuming too much fuel.
Poor ignition, sparks, or backfires.
If you are experiencing any of above problems, contact DR Power Equipment for help.

(3) Any warranted part that is scheduled for replacement as required maintenance in the written instructions required by
subsection (d) must be 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 must be repaired or replaced by RATO according to Subsection (4)
below. Any such part repaired or replaced under warranty must 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 at all RATO
distribution centers that are franchised to service the subject engine/equipments.
(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) RATO is liable for damages to other engine/equipment components proximately caused by a failure under warranty of any
warranted part.
(8) Throughout the emissions warranty period defined in Subsection (b)(2), RATO must 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 RATO.
(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 will be grounds for disallowing a warranty claim. RATO will not be liable to warrant
failures of warranted parts caused by the use of a non-exempted add-on or modified part.
