INTRODUCTION
This manual outlines the maintenance and operation of ICS® manufactured products.
This is a professional tool and is solely intended for use by trained and experienced operators.
The 890 Series chainsaw is designed to cut concrete, stone, and masonry when used with the
appropriate genuine ICS Diamond Chain. Other materials including ductile iron, cast iron or PVC
pipe require the use of ICS PowerGrit® Utility Saw Chain.
To get the maximum benefit from your saw, and ensure maximum safety, be sure to read this manual
thoroughly, and periodically review safety instructions.

IMPORTANT
WARNING
CAUTION

SAFETY
WARNING
THE FOLLOWING SYMBOL APPLIES TO ALL THE ITEMS LISTED ON THIS PAGE
A potentially hazardous situation exists which, if not avoided,
could result in death or serious injury.
Diamond chain breakage can result in high-speed ejection of parts, which can result in death
or serious personal injury to operators or bystanders. The items listed below are critical to
minimizing the risk of diamond chain breakage and injury.
• DO NOT operate a diamond chain saw with a damaged, modified, broken or missing side
cover, bottom guard or guard flap. The side cover, bottom guard and guard flap provide
protection against contact with moving parts, ejected debris, broken diamond chain,
thrown water and concrete slurry.
• DO NOT operate saw with loose, missing, damaged or improperly repaired parts.
• DO NOT exceed the hydraulic flow for your saw model: 8 gpm (30 lpm) or 12 gpm (45 lpm)
at 2,500 psi (172.5 bar) hydraulic pressure.
• DO NOT run the saw backwards. The chain should travel away from the operator on the
top of the bar and return on the bottom of the bar.
• DO NOT insert the saw into a slot narrower than the chain segments. Rapid pushback
might occur. Reference: Most diamond segments are .225 (5.72 mm) wide.
• DO NOT use the 890 Series side cover as a replacement cover for another saw.
• DO NOT use damaged, modified or improperly repaired chain.
• DO NOT run the saw upside-down. Concrete debris can fly back into the operator’s face.
• DO NOT use your hands to search for hydraulic leaks. Hydraulic fluid escaping under
pressure can penetrate skin. If any hydraulic fluid is injected into skin seek medical
attention immediately.
• Only use PowerGrit®Utility Saw Chain when cutting ductile iron pipe or like materials
with the saw. Using chain platforms not specifically designed for this type of material
may cause segment loss or diamond chain breakage.
• See page 13 for information about cutting with PowerGrit chain.

SAFETY
CAUTION
THE FOLLOWING SYMBOL APPLIES TO ALL ITEMS LISTED ON THIS PAGE
A potentially hazardous situation exists which, if not avoided,
may result in minor or moderate injury or property damage.
• Always turn the saw OFF when performing maintenance on the saw including chain
tensioning.
• Never use equipment that is not functioning properly.
• Have the saw repaired by qualified service personnel.
• Insufficient water supply may result in excessive wear to the Diamond Chain, which can
lead to loss of strength and Diamond Chain breakage. Minimum water pressure is 20 psi
(1.5 bar).
• SealPro®diamond chains require a minimum water pressure of 20 psi (1.5 bar).
Insufficient water supply may result in excessive wear to the chain, which can lead to loss
of strength and chain breakage, and/or damage to the guidebar nose sprocket.
• Never start the saw unless the guidebar, Diamond Chain and
side cover are properly installed.
GENERAL SAFETY PRECAUTIONS
• Always wear protective clothing, including hard hat, eye protection, hearing protection, and
gloves.
• Avoid loose fitting clothing.
• Perform safety checks before starting each day.
• Always operate tool with solid footing and with both hands on saw.
• Remove or control slurry to prevent slippery conditions while cutting.
• Be sure there are no obstructions (plumbing, electrical conduit, air ducts, etc.) and no
unnecessary people present.
• Set up a well-marked safety zone with a roped boundary and clear signs.
• Provide adequate ventilation when working in an enclosed area.
• To avoid electrocution, check for live electrical wiring near cutting area.

remove the side cover and bar
clamp plate.
STEP 2
Place the bar onto the studs and the
chain adjustment pin.
STEP 4
Mount the chain on the bar starting
at the drive sprocket & continue
over the bar nose.

STEP 9
Lift up on the nose of the bar and
firmly tighten the side cover nuts. To
prevent chain tensioner breakage,
be sure the side cover nuts are
tightened to approximately 20 ft-lbs
(27 Nm).
CORRECT CHAIN TENSION
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.
If the chain is too tight, a lot of the
saw's power goes into turning the
chain rather than into the cut. In
extreme over-tightened cases, the
saw may not be able to turn the
chain at all. In addition, damage
can occur to the bar nose and
premature stretch may occur.
CHAIN TOO LOOSE
If the chain is too loose, it could
come off the bar, or it will allow
the drive sprocket to spin without
turning the chain, which can
damage drive links.
When a chain stretches to a point
where the drive links are hanging
approximately 1/2 in (12 mm) to 3/4
in (18 mm) below the bar, it is time
to tension the chain.
CHAIN TOO TIGHT CHAIN TOO LOOSE
STEP 8
Tension the chain. Do not over
tension the diamond chain. Loss of
power will result.
