INTRODUCTION
The 680ES saw is designed to cut concrete, stone, and masonry when used with
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 signicant 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
signicant 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.

Safety Rules
HANDLING FUEL SAFELY
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.
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.
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.
WARNING
CAUTION
WORK AREA SAFETY
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.
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.
Drugs or alcohol can impair vision, dexterity, and judgment.
Do not operate the saw when tired or under the inuence of any substance.
Breathing exhaust gases can cause asphyxiation and carbon monoxide
poisoning in high concentrations.
Use the saw only in a well-ventilated area.

WARNING
CAUTION
Following are the basic instructions to assure work area safety.

Safety Rules
PERSONAL SAFETY
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.
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.
Following are the basic instructions to assure personal safety.
WARNING
Long-term exposure to noise can result in permanent hearing impairment.
Always wear approved hearing protection.
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.

Safety Rules
USING THE ICS SAW SAFELY
Following are the basic instructions to assure safe use of the saw. Also read and
understand additional safety precautions specic to the operation and
maintenance of the saw throughout this manual.
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 specied in this
manual on this saw.
DO NOT operate the saw with damaged, modied, 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).
WARNING
DANGER
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
Following are the basic instructions for guidebar and diamond chain installation
and tensioning.
Never perform any maintenance or adjustments on the saw while the engine is
running.
Be sure the multi-function lever is set to the “STOP” position before proceeding.
Improper chain tension can lead to failure of the chain or derailing of the chain
o of the guidebar.
Check tension frequently and adjust if drive links of chain hang 18 mm (3/4 in) or
more below the guidebar groove
Always wear gloves when handling the bar and chain.
These components can develop sharp edges and cause cuts.

CHAIN TOO TIGHT CHAIN TOO LOOSE
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).

CHECKING & ADJUSTING CHAIN TENSION
Unpacking & Assembly
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.
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.
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.
IMPORTANT
WARNING
CAUTION
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.
