the appropriate genuine ICS Diamond Chain. This is a professional tool and is
solely intended for use by trained and experienced operators. A rst time
operator should obtain practical instruction before using the saw, as well as reading
and understanding this Operator’s Manual.
Local legislation and/or workplace standards may regulate the use of this saw.
Determine what regulations are applicable in the place you work before using the
saw.
Prop 65 statement:
California Proposition 65 (the Safe Drinking Water and Toxic Enforcement Act of
1986) refers to the California legislation that was intended by its authors to protect
California citizens and the State’s drinking water sources from chemicals known
to cause cancer, birth defects or other reproductive harm, and to inform citizens
about exposures to such chemicals. Proposition 65 requires businesses to notify
Californians about signicant amounts of chemicals in the products they purchase,
in their homes or workplaces, or that are released into the environment. By
providing this information, Proposition 65 enables Californians to make informed
decisions about protecting themselves from exposure to these chemicals.
Proposition 65 also prohibits California businesses from knowingly discharging
signicant amounts of listed chemicals into sources of drinking water.
The engine exhaust from this machine and some types of dust/debris created from
its normal operation may contain chemicals known to the State of California to
cause cancer, birth defects, or other reproductive harm.
Turn o the saw, assure that the multi-function lever is set in the “STOP” position,
and allow the engine to cool a few minutes before fueling. Do not smoke or refuel
the saw in close proximity to any ignition sources. Move the saw at least 3 m (10 ft)
from the fueling area before restarting it.
Avoid spilling fuel on yourself or on the saw.
Use only approved containers to transport and store fuel. If fuel is spilled on the
saw, wipe up the spillage and allow the rest to evaporate. If fuel is spilled on
yourself or your clothes, immediately remove contaminated clothing and wash any
part of your body that has contacted fuel with soap and warm water.
CAUTION
Check saw for fuel leaks before starting.
Check regularly for leaks from the fuel cap and fuel lines and do not start saw if any
leaks are found.
WORK AREA SAFETY
Following are the basic instructions to assure work area safety.
DANGER
Breathing exhaust gases can cause asphyxiation and carbon monoxide
poisoning in high concentrations.
Use the saw only in a well-ventilated area.
WARNING
Drugs or alcohol can impair vision, dexterity, and judgment.
Do not operate the saw when tired or under the inuence of any substance.
CAUTION
Remove or control slurry to prevent slippery conditions while cutting.
This saw uses water and can cause slippery surfaces due to the slurry
produced and/or freezing temperatures.
Keep children and bystanders away from work area.
Set up a well-marked safety zone with a roped boundary and clear signs to keep
bystanders at least 6 m (20 ft) away.
Following are the basic instructions to assure personal safety.
WARNING
Always wear protective clothing.
At a minimum always wear eye protection and/or face shield, hearing protection,
long sleeve shirt, long pants, closed toe shoes with non-slip soles, and gloves. In
many work situations, a hard hat and steel toed shoes may also be required. Avoid
loose tting clothing.
Long-term exposure to noise can result in permanent hearing impairment.
Always wear approved hearing protection.
This saw can generate hazardous dust and vapors.
Determine the nature of the material you are going to cut before proceeding with
the job. Be especially aware of cutting materials containing silica and asbestos
as inhaling dust can result in respiratory disease. Be sure to use appropriate
respiratory protection designed to lter out microscopic particles. Be sure to use
adequate water pressure.
Over-exposure to vibration can lead to circulatory and/or nerve damage to the
extremities, especially in cold temperatures (Reynaud’s Disease).
If you experience tingling, numbness, pain or changes in skin color, particularly in
your ngers, hands or wrists, stop using the saw immediately. If the problem
persists, seek medical attention.
This machine produces an electromagnetic eld during operation.
This eld may under some circumstances interfere with active or passive medical
implants. To reduce the risk of serious or fatal injury, we recommend persons with
medical implants consult their physician and the medical implant manufacturer
before operating this machine.
Following are the basic instructions to assure safe use of the saw. Also read and
understand additional safety precautions specic to the operation and
maintenance of the saw throughout this manual.
DANGER
DO NOT operate the ICS saw with a saw chain or saw bar designed to cut
wood. Using wood cutting saw chain on the ICS saw could result in severe injuries
to the operator or a bystander! Use ONLY the cutting attachments specied in this
manual on this saw.
WARNING
DO NOT operate the saw with damaged, modied, broken, or missing
components.
Below safety features are designed to protect against contact with moving parts,
ejected debris, broken chain, thrown water, and concrete slurry.
• Side cover
• Mud ap
• Mud ap bracket (Chain Catcher)
• Rear hand guard
• Throttle trigger interlock
Use only Genuine ICS replacement parts. Use of unauthorized aftermarket parts
may result in injury or damage to the saw.
DO NOT insert the guidebar into a slot narrower than the width of the chain.
Rapid pushback, kickback and/or chain breakage could result.
DO NOT operate the saw without an adequate water supply.
The integral water supply channels in the guidebar act to cool and lubricate the
cutting system as well as to suppress dust and debris generated during cutting.
Assure that the water supply is capable of delivering 1.5 bar (20 psi) pressure to the
saw at a minimum ow rate of 4 lpm (1 gpm).
Never attempt to cut ductile iron pipe or similar pipe materials with the saw
unless using PowerGrit® Utility Saw Chain.
Using concrete saw chain in these applications can cause the chain to snag
abruptly in the cut which may result in chain breakage, pushback and/or kickback.
GUIDEBAR AND DIAMOND CHAIN INSTALLATION & TENSIONING
STEP 7
Check for proper tension by pulling the chain around the bar by hand.
If you cannot easily pull by hand, the chain is too tight and needs to be
loosened slightly.
CAUTION: Be aware that the guidebar rails may develop sharp edges
over time so always pull the diamond chain by the diamond segments.
STEP 8
Continue to lift up on the nose of the guidebar and firmly tighten the
side cover nuts.
NOTE: To prevent chain tensioner breakage, be sure the side cover
nuts are tightened to approximately 27 Nm (20 ft-lbs).
All chains have a tendency to stretch when used. Diamond chains stretch more
than wood cutting chains because of the abrasive materials they are cutting.
WARNING
Improper chain tension can lead to failure of the chain or derailing of the chain
o of the guidebar.
Check chain tension frequently and adjust if drive links of chain hang 18 mm (3/4 in)
or more below the guidebar.
CAUTION
Assure that proper chain tension is maintained.
If tension is set too tight, it will lead to excessive chain stretch, and most of the
saw’s power will be used just to overcome friction. In severe cases the chain may
not turn at all, and can lead to chain breakage. If the tension is set too loose, the
chain could be thrown o of the bar, or allow the sprocket to turn without turning
the chain, which will damage the drive links.
IMPORTANT
When a chain stretches to a point where the drive links are hanging approximately
12 mm (1/2 in) to 18 mm (3/4 in) below the guidebar groove, it is time to tension
the chain.
Following are the basic instructions to assure correct water supply to the saw.
WARNING
ICS® diamond saws require a continuous water supply to the guidebar and
chain. A key purpose of the supply water is dust suppression. The potential for
airborne particulates depends on many factors including, but not limited to, the
material being cut, application and cutting environment. In all cases, assure that
the water supply is capable of delivering 1.5 bar (20 psi) pressure to the saw at a
minimum ow rate of 4 lpm (1gpm).
NOTE: Local and/or regional regulation can vary widely. It is the responsibility of the
operator to wear appropriate dust protection applicable in their area and suitable to
the application.
Never operate saw with insucient water supply.
Insucient water supply will result in excessive wear to the chain, which can
lead to excessive stretch, chain breakage and/or damage to the guidebar nose
sprocket.
Attach to water supply capable of delivering 1.5 bar
(20 psi) pressure to the saw at a minimum flow rate
of 4 lpm (1 gpm). The single most important factor
an operator can control to increase chain life is to
use adequate water pressure.
Following are the basic instructions to assure safe fueling procedures.
DANGER
Fuel vapors are highly ammable.
Turn o the saw, assure that the multi-function lever is set in the “STOP” position,
and allow the engine to cool a few minutes before fueling. Do not smoke or refuel
the saw in close proximity to any ignition sources. Move the saw at least 3 m (10 ft)
from the fueling area before restarting it.
IMPORTANT
FUEL
ICS saws require the use of high quality, 90 Octane (95 RON) or higher fuel
combined with ICS 2-stroke oil (or other high quality 2-stroke oil) specically
formulated for aircooled power equipment at a mixture of 4% (25:1). Due to the
heavy duty cycle ICS saws are subjected to in concrete cutting applications, oil
mixture and fuel quality are critical to the performance and life of the engine.
ALKYLATE FUELS
Alkylate fuel (i.e. Aspen 4) is an acceptable alternative to conventional fuel when
combined with ICS 2-stroke oil (or other high quality 2-stroke oil) at a mixture of 4%
(25:1).
NOTE: If using Aspen alkylate fuel or similar, carburetor adjustments are not
necessary or recommended.
ETHANOL BLENDED FUEL
While ICS recommends using fuel that does not contain ethanol (alcohol), it is
understood that 10% Ethanol blended fuel (E10) is becoming more widespread.
ICS saws are not designed to operate with fuel containing more than 10% ethanol.
NOTE: The use of Ethanol blended fuel greater than E10 will cause improper
operation and will cause major engine failure. This type of fuel related failure is not
covered under warranty.
This saw is certied to be in conformance with Section 213 of the Clean Air Act
by the US EPA.
Failure to follow instructions on preparing the fuel and oil mixture may result in
emissions violations.
Pressure can build up in the fuel tank and container and possibly cause sudden
release of fuel vapors when the tank is opened.
Open the fuel cap slowly and always provide adequate ventilation when
handling fuel.
IMPORTANT
It is important to accurately measure the amount of oil to be mixed with gasoline
to assure that the correct mixture is obtained. When mixing small amounts of fuel,
even small inaccuracies can drastically aect the ratio of the mixture.
Always mix gasoline and oil in a clean container approved for use with fuel. Keep
fuel container closed tightly to prevent moisture from getting into the fuel. Do not
mix more than one month’s supply of fuel. This helps prevent the separation of the
2-stroke oil from the gasoline (varnishing).
Before fueling, clean the area around fuel cap on the saw to prevent dirt from
contaminating the fuel. Contamination of the fuel tank can lead to saw malfunction.
Always begin mixing fuel by pouring half the amount of gasoline to be prepared into
the mixing container. Then add the correct amount of 2-stroke oil for 4% (25:1)
mixture and nish by adding gasoline to obtain the total quantity of mixed fuel.
Shake the fuel container to thoroughly mix the gasoline and oil before adding to the
saw. The table below shows the correct quantity of two-cycle oil to be used.
FUEL MIXTURE: 4% (25:1) mixture gasoline/oil.

NOTE: If the saw is not used for an extended period of time (3 months) the fuel tank
should be emptied and cleaned.
Do not overll the fuel tank.
Should any fuel spill happen, wipe up the spillage and allow the rest to evaporate.
If fuel is spilled on yourself or your clothes, immediately remove contaminated
clothing and wash any part of your body that has contacted fuel with soap and
warm water.
Pressure can build up in the fuel tank and container and possibly cause sudden
release of fuel vapors when the tank is opened.
Open the fuel cap slowly and always provide adequate ventilation when
handling fuel.
After adding fuel, carefully install the fuel cap and tighten rmly by hand. Tip the
saw slightly to one side and check for leaks. Should any fuel leaks be
observed, do not start the saw.
Customers are encouraged to remain consistent in the fuel option they choose for
ICS saws. Alternating between options, such as going between traditional fuel to
Alkylate fuel (Aspen) and back again may have negative impacts on the engine.
Perform the following safety checks each day to be sure that the safety features
designed into the saw are functioning properly. If any items are excessively worn or
damaged, replace before use.
• With the multi-function lever set to the “STOP” position, without starting saw,
pull starter rope slowly and inspect for fraying, wear and abrasion.
• Assure vibration isolators are intact.
• With engine running and without depressing thottle trigger lockout, pull throttle
trigger and assure continuous chain movement does not occur.
• Verify at engine idle speed that the chain does not move.
Be sure that no part of the cutting system is contacting a solid object when
starting the saw.
When the multifunction lever is set to the choke and/or throttle advance position
for starting, the chain may move and cause the saw to react if the chain contacts a
solid object.
CAUTION
Move the saw at least 3 m (10 ft) from the fueling area before starting it.
Assure that secure footing is established and chain is not contacting any
objects.
When starting the saw, place the saw on clear and level ground.
IMPORTANT
Failure to break-in an engine may result in piston seizure.
It is very important to break-in a new engine to “seat” all moving parts, especially
the piston rings. To break-in the engine, run one full tank of 4% (25:1) fuel at idle,
cycling the throttle every 5 to 10 minutes to prevent loading.
Do not obstruct air intake.
Loose clothing can inadvertently be drawn into air intake and obstruct air ow
which may result in engine stall.
STOPPING THE SAW
To turn the engine o, push the multi-function lever down until engine stops. The
multi-function lever will then remain in the “STOP” position and prevent starting.
Close water valve completely.
Sudden contact of the guidebar nose with a foreign object may generate
kickback.
Remove and/or avoid any obstructions (plumbing, water supply hoses, electrical
conduit, air ducts, etc.) that may interfere with the cut.
To avoid electrocution, check for live electrical wires.
Wires may be hidden within or behind walls and/or laying around the workspace.
Assure that any ancillary electrical equipment (fans, pumps, vacuums, etc.) are
properly grounded and certied for use in the intended environment.
Always operate the saw with solid footing and both hands on the saw.
Keep your left hand on the front handle and your right hand on the rear handle.
Wrap your thumbs around the handles to assure you maintain a secure grip on
both handles.
Never operate the saw during severe inclement weather.
Freezing conditions, lightning, sudden downpours can create hazardous jobsite
conditions.
Always wear protective clothing.
At a minimum always wear eye protection and/or face shield, hearing protection,
long sleeve shirt, long pants, closed toe shoes with non-slip soles, and gloves. In
many work situations, a hard hat, steel toed shoes and a respirator may also be
required. Avoid loose tting clothing.
Cutting with the saw may generate sparks, especially when cutting through
metal (such as rebar), and may start a re in combustible materials such as dry
grass, wood and fuel.
Be sure to use adequate water pressure and have re ghting equipment readily
To assure the best performance from your ICS saw, follow all safety precautions
and recommended techniques. Additional helpful information can be obtained at
icsdiamondtools.com.
CONCRETE/MASONRY CUTTING
Planning the Cut
1. Select the proper chain type for the material being cut. Refer to the chain
selection guide in this manual. See page 44.
2. Outline the cut with a permanent marker for a visual cutting guide.
3. Avoid pinching the guidebar and chain by using shims or other
anchoring devices to stabilize the workpiece. Always
plan to cut the bottom of an opening rst, then
top or sides. Save the easiest cut for last. (see
image at right)
4. Be sure cut concrete cannot fall and injure the operator
or bystanders. As the cut is being completed, assure that
appropriate bracing is in place to control the cut section
of the workpiece. Concrete is very heavy,
one cubic foot = 30 cm x 30 cm x 30 cm = 68 kg (12 in x 12 in x 12 in = 150 lbs)
• For the straightest cuts use the “Step Cut” method:
• First score the entire cut line approximately a half-inch deep using the
nose of the guidebar.
• Next, deepen the cut by about two inches
• Then plunge all the way through and complete the cut using the
WallWalker® as a pivot point and pull on the rear handle to rotate the
bar into the cut.
• Always operate the concrete saw at full throttle. If too much force is
applied, the saw will lug or stall. The chain will not have enough speed to cut
eectively. If too little feed force is applied, the diamonds will skid and glaze
over.
• Plunge cut instead of starting at the top surface of the wall. This will reduce
chatter, extend diamond life, create a straighter cut and more quickly enable
the use of the WallWalker.
• When cutting heavy rebar, slowly “rock” the saw so that you’re always cutting
concrete as well as steel. This will help keep the diamonds exposed. Also,
expect less chain life when cutting heavy rebar.
• Expect more chain stretch when making nose-buried cuts for extended
• periods of time, as the chain does not have a chance to “throw” the slurry away
from the nose of the guidebar.
• If the saw begins to cut consistently crooked, stop the saw, remove the bar and
chain and turn the bar over and use the other side. Dress worn rails with a belt
sander.
Note: The normal life of a guidebar is two to three diamond chains. Heavy rebar
can shorten guidebar life.
• The guidebar is solely a guide track for the chain. Never use the guidebar to lift,
twist or pry concrete material
• When using a new chain, you can increase the initial cutting speed by “opening
up the diamonds”. This can be accomplished by rst making a few cuts in an
abrasive material such as a cinder block or brick.
When transporting or storing fuel, always use a container approved for fuel and
assure it is sealed against leaks and/or escaping fumes. Contact with an ignition
source could cause re or explosion.
CAUTION
Always carry the saw by the front handle with the multi-function lever set to
the “STOP” position and away from your body
When transporting the saw, assure it is secured to avoid damage and/or personal
injury. Proper handling of the saw will reduce the likelihood of accidental contact
with the guidebar and chain.
IMPORTANT
ICS recommends mixing fuel in small batches, to be used within 30 days. Fuel
stabilizers (additives) can prolong the life of the fuel, but still should not be stored
longer than 90 days.
1. After cutting, pull trigger to spin the chain for at least 15 seconds with the
water on to ush slurry and debris from chain, guidebar and drive sprocket.
2. Stop saw and wash concrete slurry from saw assembly with special attention
to the starter housing and ywheel. Do not let slurry dry on saw as it will be
very dicult to remove later.
3. Avoid getting any water in the carburetor or exhaust system. If water enters the
exhaust port, it can enter the carburetor. To make sure there is no water in the
exhaust system, assure the multi-function lever is set to “STOP” position, point
the guidebar tip down and pull the starter handle several times to expel water
from muer.
4. Remove the chain and guidebar. Flush out the chain tensioner and side cover
with water. Lubricate tensioner with waterproof grease.
5. After cleaning the saw, spray the entire saw body, chain, guidebar, and drive
sprocket with lightweight oil. Using lightweight oil on the saw will minimize rust
and help reduce slurry build up.
6. Inspect and tighten all fasteners as necessary.
7. Inspect drive sprocket for wear. Replace if tooth tips are pointed, or if groove
cuts through top of tooth.
8. Check clutch cup needle bearing for wear. Assure clutch cup spins freely and
without excessive play.
9. Check starter cord for wear or damage. Replace as necessary.
10. Inspect air lter. Replace lter if dirty or wet.
11. Spray lightweight oil into the air intake slots on the starter housing and ywheel
(this will prevent the starter pawls from sticking).
AFTER EVERY 10 HOURS OF USE
1. Remove the starter cover and clean the ywheel ns and the starter pawls with
a wire brush, then apply waterproof grease to the starter pawls.
2. Remove the spark plug and clean with a wire brush. Check the electrode gap.
The correct gap is 0.5 mm (0.020 in). Replace if necessary.
AFTER EVERY 40 HOURS OF USE
Change the spark plug. Adjust the electrode to 0.5 mm (0.020 in).
1.
2. Check the fuel lter located inside the fuel tank. Clean or replace if clogged.
• Clean the spark plug with a wire brush and check to assure the plug gap is 0.5
mm (0.020 in).
• Inspect the spark plug boot, replace if needed.
• Inspect lead wire for wear or damage. Replace if necessary (lead wire cannot
be replaced separately from ignition module).
IMPORTANT
• Replace spark plug after 40 hours of use, or if the electrode is corroded or
eroded.
• Always use a recommended spark plug (resistor type) to prevent damage to
the piston and cylinder. (NGK #BPMR8A or Champion RCJ7Y or equivalent).
CARBURETOR
• The function of the carburetor is to mix fuel with air. Adjustments other than
idle speed should only be made by an authorized service center.
• Before adjusting the engine idle speed, make
sure the air lter is clean, the engine is running,
warmed up and the guidebar and chain are
assembled on the saw.
• Adjust idle screw so that the engine idles smoothly
but the clutch does not engage. If the chain begins
to spin, turn the idle screw counter-clockwise until the
chain stops.
• If saw has been running satisfactorily and there is a
gradual decrease in power and drop in RPM at full
throttle, the lter may have become dirty or wet. (See air lter section).
Carburetor idle screw
STARTER RECOIL HOUSING
It is common for concrete slurry to get inside the
starter housing assembly during cutting. This can
cause starter pawls to stick and not engage when the
rope is pulled.
• After each usage, thoroughly ush the starter
housing assembly with water.
• Spray lightweight oil into the air intake slots on the
starter housing and ywheel (this will prevent the starter pawls from sticking).
• Inspect the starter cord for fraying, replace if necessary.
• Loosen the four screws that attach the starter cover assembly to the
crankcase, and remove the starter cover assembly from the saw.
• Remove starter cord shield screws.
• Pull 10 - 15 cm (4-6 in) of rope out.
• Line rope up with notch on pulley.
• Using your thumb on the pulley as a brake, slowly
rotate pulley counter-clockwise until spring pressure
is released.
• Remove starter pulley screw and washer.
NOTE: Hold starter cover firmly.
• Remove starter pulley.
• Clean and inspect the pulley spring catch, replace if worn or broken.
• Install starter rope and tie knot at pulley end.
• Wind rope onto pulley clockwise, leaving 10 - 15 cm (4 - 6 in) from the handle
end, and install pulley.
NOTE: Assure that the pulley spring catch is in the spring hook.
• Install center screw, spacer and washer.
Use Loctite
Torque to 2.9 Nm (26 in-lbs).
• Assemble starter cord shield.
® .
242.
TENSIONING THE RECOIL SPRING
• Hook the rope in the notch of pulley and wind the rope
clockwise three times around the raised center of the
pulley.
• Pull the starter rope with the handle until the rope is
unwound, tensioning the spring. Repeat this process,
but this time, wind the rope clockwise four times around
and then pull the rope with the handle to complete the
tensioning of the spring.
NOTE: When released, the starter handle should be drawn to the correct start
position after tensioning the spring.
IMPORTANT
Check that the pulley can be turned an additional 1/2 turn when the starter cord
is pulled all the way out.
• The drive sprocket (rim sprocket) is a wear item and
Clutch
Cup
Splined
Adapter
Rim
Sprocket
should be replaced every two to three chains, or
when the teeth become pointed or if groove cuts
through top of tooth.
• Inspect the sprocket for wear.
• The needle bearing inside the splined adapter
should be greased regularly and should be replaced
with each new clutch cup. A rim sprocket system
consists of a clutch cup w/ splined adapter and a rim
sprocket. When the rim sprocket wears out, it is the only part that needs to
be replaced. The clutch cup with splined adapter is a wear item that needs
replacement after 3 to 5 rim sprockets have been used.
• Check the drive sprocket bearing by spinning clutch cup. Replace the
bearing if it is worn out.
DRIVE SPROCKET ASSEMBLY REMOVAL/INSTALLATION
• Remove the side cover, guidebar, diamond chain, and clutch slurry shield.
• Remove the spark plug and insert the piston stop (supplied with each saw)
into the spark plug hole.
Pull the starter cord slowly until the piston stops. Use a 19 mm wrench to turn
the clutch clockwise and remove.
• Slide the clutch cup/drive sprocket assembly off the
shaft. Remove the needle bearing and inspect for
heavy wear or damage.
• Slide the rim sprocket onto the splined adapter,
either side out.
• Apply a liberal amount of grease to the needle
bearing.
• Place the thin metal washer onto drive shaft. Slide the needle bearing and
clutch cup w/rim sprocket onto shaft.
• Install the clutch by turning it counter clockwise on the drive shaft and
firmly tighten. Replace the clutch slurry shield. Installation of drive sprocket
assembly is now complete.
Inspect chain segments and drive links for damage or excessive wear. Chains
with damage or excessive wear should not be used or repaired, they should be
replaced.
NOTE: Guidebars are designed to be used on both sides. If the cut is consistently
leading to one side, turn the guidebar over. It is recommended to turn the guidebar
over with every new chain.
• A table mounted belt or disc sander can be used to square the rails of a worn
guidebar. A badly worn guidebar can quickly damage the chain. If the chain is
touching the bottom of the guidebar groove, replace the guidebar.
• Check the guidebar for straightness.
• Proper chain tension will extend guidebar life.
• Under some circumstances, especially low water pressure, the sprocket nose
can wear out before the guidebar body. Sprocket nose assemblies may be
replaced by an Authorized Service Center.
• Periodically clean the water ports inside the groove of the guidebar using a
small diameter piece of wire or pipe cleaner.
• The guidebar is solely a guide track for the chain. Never use the guidebar to lift,
twist or pry concrete material.
• Prior to storage, spray the chain and guidebar with lightweight oil.
Chain tension too tight. Chain should always be able to

on your 2009 and later small non-road engine. In the U.S. and Canada, new
small non-road engines must be designed, built and equipped to meet federal
emission regulations.
ICS® must warrant the emission control system on your small non-road engine
for the period of time listed below provided there has been no abuse, neglect or
improper maintenance of your unit.
Your emission control system includes parts such as the carburetor and the
ignition system. Also included may be hoses, connectors and other emission
related assemblies.
Where a warrantable condition exists, ICS will repair your saw engine at no cost
to you. Expenses covered under warranty include diagnosis, parts and labor.
MANUFACTURER’S WARRANTY COVERAGE
The emission control system on 2009 and later small non-road engines is
warranted for two years. If any emission related part on your engine (as listed
above) is defective, the part will be repaired or replaced by ICS.
As the saw owner, you are responsible for the performance of the required
maintenance listed in your Operator's Manual. ICS® recommends that you
retain all receipts covering maintenance on your saw engine, but ICS cannot
deny warranty solely for the lack of receipts or for your failure to assure the
performance of all scheduled maintenance. However, ICS reserves the right to
deny warranty coverage if your saw engine, or a part of it, has failed due to abuse,
neglect, improper maintenance, unapproved modifications or the use of parts
not made or approved by the original equipment manufacturer.
You are responsible for presenting your saw engine to an ICS authorized
servicing dealer as soon as a problem exists. The warranty repairs should be
completed in a reasonable amount of time, typically not to exceed 30 days.
If you have any questions regarding your warranty rights and responsibilities,
please contact an ICS customer service representative at 1.800.321.1240.
