COLD ENGINE STARTING PROCEDURE
1. Pull the choke lever out.
2. Lock the throttle in the start position by depressing and holding the throttle lock
button (C) while releasing the trigger (A) and trigger interlock (B) in succession.
WARM ENGINE STARTING PROCEDURE
1. Use the same procedure as starting cold engine, but DO NOT pull choke lever out. If choke is used, the carburetor will flood
with gas.
2. If the engine does not start in 3 hard, fast pulls with the throttle locked, unlock the throttle and pull the starter cord 3 more times.

HOW TO TENSION
To tension the chain, first loosen the side cover nuts, then while holding the nose of the
bar up, use a screw driver to turn the tensioning screw clockwise until the chain drive
links hanging below the bar are just beginning to enter the bar groove. Continue to hold
up on the nose of the bar and firmly tighten the side cover nuts, (20 ft-lbs, 27 Nm). And
remember, it’s the side cover nuts that hold the bar in position.
HOW TO PREVENT CHAIN TENSIONER BREAKAGE
Do not attempt to adjust the tensioner without first loosening the side cover nuts. Do not
use the saw without making sure the side cover nuts are tight. If the side cover nuts are
not tight, the bar can slip backwards during cutting and break the tensioner pin.
PROPER CHAIN TENSION
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 chew up the chain drive links. 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.
WHEN TO 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. When a chain stretches
to a point where the drive links are hanging approximately 1/2 in- 3/4 in (12 - 18 mm)
below the bar, it’s time to tension the chain.
HOW TO CHECK
Before cutting, 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.
IMPORTANT
A properly tensioned chain will optimize cutting performance. The tensioning rule of thumb
for a concrete cutting chain saw is that a properly tensioned diamond chain must not be
bowstring tight and can be pulled freely around the guide bar by hand easily without
binding.

ADDITIONAL TENSIONING TIPS:
1. To reduce chain stretch and tensioning downtime, use 20 psi (1.5 bar) or greater water pressure.
2. Oil the chain at the end of the day to prevent rust but be careful not to over tension in this condition.
3. When pulling the chain around the bar by hand, be careful not to touch the bar with thumb or forefinger. The bar rails can be
very sharp. Grab only the diamond segments to pull the chain.
4. Always pull the chain away from the WallWalker®. The point of the WallWalker® can also be very sharp.
5. Always turn the engine off before tensioning the chain.
ADDITIONAL INFORMATION
Concrete cutting chainsaws operate with looser chain tension than wood
chainsaws. It is common, especially on gas powered, concrete cutting
chainsaws to have the drive links hang completely out of the bar. Wood
cutting chainsaws use oil to lubricate the chain. The oil makes the chain
very slippery and allows the drive links to fully nest between the teeth of
the drive sprocket. Concrete cutting chainsaws require water for cooling
and flushing the cut. Water is not as good as oil as a lubricant. Also, there
are concrete particles mixed in with the water. As a result, sometimes the
drive links do not nest properly on the drive sprocket. When this happens,
the chain acts like it got tighter. There seems to be tight spots and loose
spots as you pull the chain around the bar. If you tension when the chain
is in one of the loose spots, it will be too tight at some point in it’s rotation
around the bar. Rotating the chain completely around the bar by hand will
let you know you have the chain properly tensioned.

5 PROBABLE CAUSES IF SAW IS REPORTED “NOT ABLE TO START” or “WON’T RUN WELL”
Diagnose in the order below:
1. AIR FILTER
IDENTIFICATION A gradual decrease in power or loss of full throttle RPM.
CAUSE The air filter is dirty and/or clogged.
FIX Remove and clean/replace air filter.
NOTES 1. Refer to Operator’s Manual for cleaning procedures.
2. A dirty air filter will contribute significantly to engine flooding, spark plug build-up and/or low compression failures.
2. STARTER
IDENTIFICATION The starter rope pulls freely without noticeable resistance.
CAUSE Concrete slurry will get inside the starter housing assembly during cutting, causing the starter pawls to stick and not engage
when the rope is pulled.
FIX Remove starter assembly and clean or replace starter and lube with lightweight penetrating oil (WD40/TriFlow). For starter
assembly repair or installation, refer to Operator’s Manual.
NOTES 1. Cutting with saw in horizontal position with flywheel down accelerates slurry collection. Immediately wash starter assembly
after use in this mode.
2. Clean or replace the appropriate starter cover assembly components when you encounter a starter with a frayed starter
cord, broken rewind spring, or other mechanical damage.
3. FLOODED ENGINE
IDENTIFICATION Smell of fuel and/or a wet, fuel soaked spark plug after removal.
CAUSE Commonly caused by leaving choke on after first ignition spark. May also be caused by excess rope pulls.
FIX Remove spark plug and pull rope to discharge excess fuel from cylinder. Air dry spark plug or replace with correct spark plug
4. IGNITION
IDENTIFICATION No obvious fuel issues and a spark plug not showing visible spark after removal and test per method in Note 1 below.
CAUSE The spark plug is most likely dirty or contaminated. A secondary cause is an improper spark plug gap.
FIX Remove spark plug and clean or replace. Re-gap spark plug to .020 in (0.05 mm). Refer to Operator’s Manual for more details.
If no spark is visible or if the spark is weak (yellow in color), replace ignition system coil.
NOTES 1. Test method: Always ensure ignition switch is ON. Remove plug and connect the plug lead to a new spark plug. Place plug
on top of cylinder to ground and crank the engine several times by pulling the recoil starter. A healthy ignition should produce
a strong blue spark.
5. LOW COMPRESSION
IDENTIFICATION The starter rope pulls upwards with very little resisting force from piston. If possible, this should be verified with a compres-
sion gauge or by an ICS Servicing Dealer (see Note 1).
CAUSE Piston scoring/wear or stuck piston rings.
FIX Contact ICS Servicing Dealer or Factory Service Center for evaluation
NOTES 1. If compression is checked with a compression gauge, a reading below 125 psi indicates piston damage.
New saw compression is 160 psi.

MAKING YOUR FIRST CUT:
1. Outline the cut with a permanent marker.
2. Start the saw and after a brief warm-up period, rev and hold the trigger on full throttle. Always use full throttle when cutting.
Refer to “Starting the Saw” tip sheet.
3. Carefully align the nose of the bar with the cut line, slowly touch the wall with the chain and plunge straight into the wall.
4. Push hard enough so that the engine RPM drops 20 to 30%. If the chain is stalling in the cut, you’re pushing too hard. If there is
very little difference between free running full RPM and the cutting RPM, you’re not pushing hard enough. Listen for the “sweet
spot” and maintain that RPM throughout any cut.
5. Keep steady, firm pressure on the saw as the chain is cutting. This will prevent chain bounce and chattering and help extend
diamond life. Minimize arm motions.
6. Use the WallWalker® to make cutting easier. Insert the point of the WallWalker® into the cut and pull up on the rear handle. If saw
is equipped with rubber pad WallWalker®, use the rubber pad for leverage in the same way.

ADDITIONAL CUTTING TIPS:
a. For the straightest cuts use the Step Cut method. After outlining the cut, score the entire cut line approximately a half-inch
deep using the nose of the bar. Next deepen cut by about two inches. Then plunge all the way through and complete the cut using
the WallWalker® as a lever.
b. Plunge cut instead of starting on top of a wall. Plunge cutting generally results in a straighter start. If the cut doesn’t start
straight, it will not finish straight. Also, plunging is the fastest and easiest mode of cutting.
c.When cutting heavy rebar. Slowly rock the saw over the rebar, maintaining gray slurry water, 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.
d. Maintain proper chain tension. The tensioning rule of thumb for a chain-based cut-off saw is that the chain should be tight but
must be able to be pulled around the bar by hand. See “Chain Tensioning” tip sheet.
e. If the saw begins to cut consistently crooked. Turn the guide bar over and use the other side. If problem persists, dress the
worn rails with belt grinder. Note: The normal life of a guide bar is 2 to 3 chains. Heavy rebar can shorten bar life.
f. When using a new chain, it may be necessary to open up the diamonds. To do this, make a few cuts into an abrasive material
like a cinder block. Opening the diamonds will increase the cutting speed.

AFTER EACH USE
1. Rinse the saw, bar, and chain with water.
2. Follow instructions on the Daily Maintenance Label, located on the air filter cover.
3. Inspect and tighten all fasteners as necessary.
4. Inspect drive sprocket for tooth wear. Replace if tooth tips are pointed.
5. Inspect the starter cord. Replace if frayed.
6. Clean and inspect air filter. Replace as necessary.
7. Spray saw, bar, and chain with lightweight oil.
8. Grease the chain tensioner.
AFTER 10 HOURS OF USE
1. Remove the starter cover and lubricate the starter recoil spring. Clean the flywheel fins and the starter pawls with a wire
brush, then grease the starter pawls.
2. Remove the spark plug and clean with a wire brush. Check the electrode gap. The correct gap is 0.02 inches (0.5 mm).
AFTER 40 HOURS OF USE
1. Change the spark plug. Adjust the electrode to 0.02 inches (0.5 mm).
