Please read this section carefully. Operate the edger
according to the safety instructions and recommendations outlined here and inserted throughout the text.
Anyone who uses this edger must read the instructions
and be familiar with the controls.
IMPORTANT
INDICATES HELPFUL INFORMATION FOR PROPER
ASSEMBLY, OPERATION, OR MAINTENANCE OF YOUR
EQUIPMENT.
ENGINE SAFETY PRECAUTIONS
Warning Carbon Monoxide Poisoning
All engines contain carbon monoxide in their exhaust.
Carbon monoxide is a deadly, colorless, tasteless, odorless
gas which may be present even if you do not smell or see
any engine exhaust. Levels of carbon monoxide, which can
be deadly, can be present for days in an enclosed area
that has poor ventilation. Any level of carbon monoxide,
if inhaled, can cause headaches, drowsiness, nausea,
dizziness, confusion and eventually death. If you experience
any of these symptoms, seek fresh air and medical attention
immediately.
Preventing Carbon Monoxide Poisoning
• Never run engine indoors.
• Never try to ventilate engine exhaust indoors. Carbon
monoxide can reach dangerous levels very quickly.
• Never run engine outdoors where exhaust fumes may
be pulled into a building.
• Never run engine outdoors in a poorly ventilated area
where the exhaust fumes may be trapped and not easily
taken away. (Examples include: in a large hole or areas
where hills surround your working area.)
• Always run the engine with the exhaust from the muffler
pointed in the direction away from the operator.
• Never point the exhaust from the muffler towards
anyone. People should always be many feet away from
the operation of the engine and its attachments.
Gasoline Fires and Handling Fuel Safely
Fuel and fuel vapors are highly flammable. Never use fuel
where a spark or flame may be present. Never use fuel
where a potential source of ignition could occur. (Examples
include: hot water or space heaters, clothes dryer, electric
motors, etc.) Keep flames and sparks away from engine
and fuel to prevent fires. Fuel fires spread very quickly and
are highly explosive.
Prevention of Gasoline Fires
• Never fill your fuel tank with fuel indoors. (Examples
include: basement, garage, barn, shed, house, porch,
etc.)
• Always fill fuel tank outside in a well ventilated area.
• Never remove the fuel cap or add fuel with the engine
running. Stop engine and allow to cool before filling.
• Never drain fuel from engine in an enclosed area.
• Always wipe up excess (spilled) fuel from engine before
starting. Clean up spilled fuel immediately.
• Allow spilled fuel to dry, after wiping and before
starting.
• Allow fuel fumes/vapors to escape from the area before
starting engine.
• Test the fuel cap for proper installation before starting
and using engine.
• Always run the engine with fuel cap properly installed
on the engine.
• Always unscrew gas cap vent screw while engine is
running.
• Never smoke while refilling engine fuel tank.
• Prevent fire and explosion caused by static electric
discharge. Use only nonmetal, portable fuel containers
approved by the Underwriter’s Laboratory (U.L.) or the
American Society for Testing & Materials (ASTM).
• Do not store engine with fuel in fuel tank indoors. Fuel
and fuel vapors are highly explosive.
• During storage, screw down gas cap vent screw
tightly.
• Never pour fuel from engine fuel tank.
• Never siphon fuel by mouth to drain fuel tank.
800-345-6007
Page 7
Page 8
GetEarthquake.com
• Always have an adult fill the fuel tank.
• Never allow an adult or anyone under the influence of
drugs or alcohol to fill fuel tank.
• Never allow children to fill the fuel tank.
• The clutch will transfer maximum power after about two
hours of normal operation. During this break-in period
clutch slippage may occur. The clutch should be kept
free of oil or other moisture for efficient operation.
BURNS AND FIRES
The catalytic converter muffler, muffler guard and other
parts of the engine become extremely hot during the
operation of the engine. These parts remain extremely hot
after the engine has stopped.
Prevention of Burns and Fires
• Never remove the muffler guard from the engine.
• Never touch the muffler guard because it is extremely
hot and will cause severe burns.
• Never touch parts of the engine that become hot after
operation.
• Always keep materials and debris away from muffler
guard and other hot parts of the engine to avoid fires.
This engine is designed to operate using a catalytic converter which contributes to the engine’s compliance with
the EPA.

or modifications not recommended or approved in writing by

b) Replacement of parts and other services and adjustments
necessary for required maintenance at or after the first scheduled replacement point;
c) Consequential damages such as loss of time, inconvenience,
loss of use of the engine or equipment, etc.
d) Diagnosis and inspection fees that do not result in eligible

all material respects to the engine described in the manufacturer's
application for certification. The warranty period begins on the
date the engine is originally purchased.
MAINTENANCE AND REPAIR REQUIREMENTS
The owner is responsible for the proper use and maintenance
of the engine. Ardisam, Inc. recommends that all receipts and
records covering the performance of regular maintenance be
retained in case questions arise. If the engine is resold during the
warranty period, the maintenance records should be transferred
to each subsequent owner. Ardisam, Inc. reserves the right to
deny warranty coverage if the engine has not been properly
maintained; however, Ardisam, Inc. may not deny warranty repairs
solely because of the lack of repair maintenance or failure to keep
maintenance records.
Normal maintenance replacement or repair of emission control devices
and systems may be performed by any repair establishment or individuals; however, warranty repairs must be performed by an Ardisam
authorized service center. Any replacement parts or service that is
equivalent in performance and durability may be used in non-warranty
maintenance or repairs, and shall not reduce the warranty obligations
of the engine manufacturer.
The warranty on emissions-related parts is as follows:
• 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, that part will be repaired or replaced at no
charge to the owner. Any such part repaired or replaced under the
warranty will be warranted for the remaining warranty period.
• Any warranted part that is scheduled only for regular inspection
in the owner's manual supplied, is warranted for the warranty
period. Any such part repaired or replaced under warranty will be
warranted for the remaining warranty period.
• 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 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.
• Add on or modified parts that are not exempted by the Air
Resources Board may not be used. The use of any nonexempted
add on or modified parts by the owner 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
nonexempted add on or modified part.
