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.

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 chain breakage and injury.

• DO NOT operate a concrete chain saw with a damaged, modified, broken, or missing side

cover, bottom guard, or guard flap. The side cover, bottom guard, and guard flap provides

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 insert saw into a slot narrower than the chain segments. Rapid pushback might

occur. Reference: Most diamond segments are .225 inches (5.72 mm) wide.

• DO NOT use damaged, modified or improperly repaired chain.

• DO NOT run saw upside-down. Concrete debris can fly back into the operator’s face.

• DO NOT cut ductile iron pipe with the concrete chain saw (except when using PowerGrit®

Utility Saw Chain). Segment loss or diamond chain breakage may occur.

• See page 16 for information about cutting ductile iron pipe 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 a concrete chain saw OFF when performing maintenance on the saw

including chain tensioning.

• Never use equipment that is not functioning properly.

• Have the saw repaired only by qualified service personnel.

• Turn engine OFF before refueling. Keep away from open flame. Always provide adequate

ventilation when handling fuel. Move saw at least 10 feet (3 m) away from refueling area

before starting.

• 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 saw unless the bar, 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) 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. Breathing exhaust gases is

dangerous.

• To avoid electrocution, check for live electrical wiring near cutting area.

SAFETY

IMPORTANT

THE FOLLOWING SYMBOL APPLIES TO ALL ITEMS LISTED ON THIS PAGE

A potential situation exists which, if not avoided, may result in

product or property damage.

Note: The concrete chain saw is equipped with a 2-stroke engine and must always be run

using a mixture of gasoline and ICS®2-stroke engine oil, or other high quality 2-stroke

oil that has been formulated for air cooled power equipment. It is important to accurately

measure the amount of oil to be mixed to ensure that correct mixture is obtained. When

mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the

mixture.

ENGINE BREAK-IN

• 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 25:1 (4%) fuel at idle, cycling the throttle every

5 to 10 minutes to prevent loading.

• Failure to break-in an engine may result in piston seizure.

• This engine is designed to be operated on premium unleaded gasoline.

• Use high quality, unleaded gasoline with a minimum octane rating of 90. If lower octane

gasoline is used, engine temperature will increase which can result in a piston seizure

and damage to the engine.

• Fuel mixture: 25:1 (4%) gasoline/oil mixture. Incorrect fuel mixture is the number one

cause of piston seizure.

• Use ICS®brand 2-stroke engine oil, or other high quality 2-stroke oil that has been

formulated for air cooled power equipment.

• Never use two-stroke oil formulated for water-cooled two-cycle engines, such as

outboard motor oil.

• Never use motor oil intended for four-stroke engines.

SET-UP

STEP 1

Loosen side cover nut and remove side

cover.

GUIDEBAR AND DIAMOND CHAIN INSTALLATION

STEP 3

Mount the diamond chain on the guidebar

starting at the drive sprocket and continue

over the guidebar nose.

NOTE: FORCE4 requires rim to be pulled

outward for chain installation.

STEP 4

Install the side cover and ensure chain

adjustment pin engages hole in bar. Do not

fully tighten side cover nut until after chain

is properly tensioned.

STEP 2

Place bar onto stud and engage alignment

block.

TITLE 695GC / 695F4 OPERATOR’S MANUAL

SET-UP

GUIDEBAR AND DIAMOND CHAIN INSTALLATION

STEP 6

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 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 5

Make sure all the drive links are inside

the guidebar groove then lift the bar nose

and tension the chain by turning the screw

clockwise.

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

oc cur.

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

chew up 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.

STEP 7

Continue to lift up on the nose of the

guidebar and firmly tighten the side cover

nut.

NOTE: To prevent chain tensioner

breakage, be sure the side cover nut

is tightened to approximately 20-25 ft-lbs

(27-33 Nm).

STEP 8

Attach to water source with pressure of not

less than 20 psi (1.5 bar).

• Use premium unleaded gasoline with a minimum octane rating of 90. If lower octane gasoline is

used, engine temperature will increase which can result in a piston seizure and damage to the

engine.

• Always provide adequate ventilation when handling fuel.

• Use caution when handling gasoline. Avoid direct contact with skin or inhaling fuel vapor.

FUEL MIXING

• Always mix gasoline and oil in a clean container intended for use with fuel.

• Keep fuel container closed tightly to prevent moisture from getting into the fuel.

• Always begin mixing fuel by adding half the amount of gasoline to be used. Then add the correct

amount of 2-stroke oil for 25:1 (4%) mixture and finish filling the container with gasoline.

• 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).

• If the saw is not used for an extended period of time (3 months) the fuel tank should be emptied

and cleaned.

FUELING

• Always shut off the saw before fueling.

• Before fueling, clean the area around fuel cap to prevent dirt from contaminating the fuel.

Contamination of the fuel tank can lead to saw malfunction.

• Thoroughly mix the fuel in it’s container before fueling.

• Slowly open the fuel cap to release any pressure that may have built-up in the tank.

• After adding fuel, tighten the fuel cap carefully and secure with a wrench.

CAUTION

STARTING AND STOPPING A CONCRETE CHAIN SAW

Never start a concrete chain saw without the bar, chain and side

cover properly assembled. Failure to do so may result in serious

injury.

Always move a concrete chain saw at least 10 feet (3 m) away

from the fueling area before starting.

Place the saw on clear ground. Ensure that secure footing is

established and chain is not contacting any objects.

IMPORTANT

WARNING

WARM ENGINE STARTING PROCEDURE

1. Use the same procedure as starting a cold engine, but pull choke lever out, and then push back in to set

the throttle lock. If choke is used on a warm engine, the carburetor will flood with gas.

2. If the engine does not start in 3 hard, fast pulls with the throttle locked, fully squeeze and hold the trigger

while pulling the starter cord 3 more times.

Note: To hold the trigger fully open it may be necessary to insert right foot into rear handle opening

and twist.

PRE-CUT CHECKLIST

• Ensure proper chain tension: The chain should be easily pulled around the guidebar by hand.

• Ensure all safety devices are properly mounted and functional and that all controls are in proper

working order.

• Be sure there are no obstructions (plumbing, electrical conduit, air ducts) and no unnecessary

people present.

• Always wear protective clothing, including hard hat, eye protection, hearing protection, non-slip

safety boots, and gloves. Avoid wearing loose fitting clothing.

• Adequate Water Supply and Pressure:

Minimum Flow: 2 gpm (8 lpm)

Minimum Water Pressure: 20 psi (1.5 bar)

• Diamond chains with SealPro® require a minimum

water pressure of 20 psi (1.5 bar).

PLANNING THE CUT

• Select the proper chain type for the material being cut.

• Outline the cut with a permanent marker for a visual cutting guide.

• Avoid pinching the guidebar and chain. Always cut the bottom of an opening first, then top, and

then the sides. Save the easiest cut for last.

• 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 bar. Next, deepen the cut by about two inches. Then plunge

all the way through and complete the cut using the WallWalker®.

• Be sure cut concrete cannot fall and injure operator or bystanders. Concrete is very heavy,

one cubic foot = 12 in x 12 in x 12 in = 150 lbs (30 cm x 30 cm x 30 cm = 68 kg).

• Check for and remove any obstructions (plumbing, electrical conduit, air ducts, etc,) that may

interfere with the cut.

The single most important factor an operator can control to

increase chain life is to use adequate water pressure. Insufficient

water supply will 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.

IMPORTANT

OPER ATION

TITLE695GC / 695F4 OPERATOR’S MANUAL

CUTTING WITH THE 695GC

To start a cut, hold trigger on full throttle and slowly plunge the nose of the bar straight into the wall.

Lengthen the cut and engage the point of the WallWalker®. Use the WallWalker as a pivot point and

pull up on the rear handle to rotate the bar into the cut.

CUTTING TIPS

• Always operate the concrete chain 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 effectively. If too little feed force is applied,

the diamonds will skid and glaze over.

• For straighter cuts use the “Step Cut” method. First score the entire cut line with the nose of the

guidebar approximately 1/2 in (12 mm) to 1 in (25 mm) deep. Next, deepen the cut by about 2

in (50 mm). This groove will help guide the guidebar for a straight cut. Then plunge all the way

through and complete the cut using the WallWalker.

• 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.

• Use the WallWalker to help cut more efficiently

and reduce operator fatigue. The WallWalker is

a fulcrum that can be used to apply additional force

when cutting. To use correctly, plunge into the wall

and simply engage the point of the WallWalker

into the cut and pry upward with the rear handle.

• As the saw begins to rotate up, feed force is developed

down the line of the intended cut. Once the saw is fully

rotated upwards, pull the saw out of the cut a few

inches and re-engage the pick into the cut and repeat.

• 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 bar.

• If the saw begins to cut consistently crooked, turn the bar over and use the other side. Dress

worn rails with belt sander. Note: The normal life of a guidebar is two to three diamond chains.

Heavy rebar can shorten guidebar life.

• When using a new chain, you can increase the initial cutting speed by “opening up the

diamonds”. Make a few cuts in an abrasive material such as a cinder block.

OPER ATION

SYSTEM CLEAN-UP

• After cutting, run the saw for at least 15 seconds with the water on to flush slurry and debris from

chain, bar and drive sprocket.

• Wash concrete slurry from saw assembly.

• Avoid getting any water in the carburetor or exhaust system. If water enters exhaust port, point

the bar tip down and pull the starter handle several times to expel water from muffler.

• Remove bar and chain. Flush out the chain tensioner and side cover with water. Lubricate

tensioner with grease.

• After cleaning the saw, spray the entire saw body, chain, bar, and drive sprocket with lightweight

oil. Using lightweight oil on the saw will minimize rust and help reduce slurry build up.

CUTTING DUCTILE IRON PIPE WITH THE POWERGRIT®UTILITY SAW CHAIN

NEVER cut ductile iron pipe with the saw unless using PowerGrit Utility Saw Chain. The following

are safety precautions that should always be followed when using PowerGrit.

• Before cutting, make sure the pipe is in a safe condition to

be cut. Support the work piece in such a way that the cut

remains open during the cutting operation and when the cut is

finished. Pinching the chain during the cut could cause chain

breakage and could result in death or serious injury to the

operator.

WARNING

TITLE695GC / 695F4 OPERATOR’S MANUAL

MAINTENANCE

Follow these simple maintenance guidelines

and your saw will continue running at its very best.

AFTER EACH USE

1. Rinse the saw, guidebar and diamond chain with water.

2. Inspect and tighten all fasteners as necessary.

3. Inspect, flush and grease the chain tensioner.

4. Inspect drive sprocket for wear. Replace if tooth tips are pointed, or if groove cuts through top of

tooth.

5. Check clutch cup needle bearing for wear. Ensure clutch cup spins freely and without excessive

play.

6. Check starter cord for wear or damage. Replace as necessary.

7. Inspect air filter. Replace filter if dirty.

8. Spray saw, guidebar, and chain with lightweight oil.

9. Spray lightweight oil into the air intake slots on the starter housing to keep starter pawls from

sticking.

AFTER 10 HOURS OF USE

1. Remove the starter cover and 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

0.020 inches (0.5 mm).

3. Grease the clutch cup needle bearing,

AFTER 40 HOURS OF USE

1. Change the spark plug. Adjust the electrode to 0.020 in (0.5 mm).

2. Check the fuel filter located inside the fuel tank. Clean or replace if clogged.

TITLE 695GC / 695F4 OPERATOR’S MANUAL

AIR FILTER

The polyester air filter must be kept clean for the engine to

operate properly. If the saw is not reaching full RPM, most likely

the air filter is dirty.

IMPORTANT

• The air filter should be free of holes and white in color.

• Replace air filter when dirty.

• When replacing the air filter, clean the area inside the air

intake housing with a clean rag prior to installing new filter.

STARTER HOUSING ASSEMBLY

It is common for concrete slurry to get inside the starter housing

assembly during cutting. This can cause the starter pawls to stick

and not engage when the rope is pulled.

IMPORTANT

• After each usage, thoroughly flush the starter housing

assembly with water.

• Oil the starter pawls by spraying lightweight oil into the

starter housing through the vents.

• Check the starter cord for fraying, replace if necessary.

MAINTENANCE

TITLE695GC / 695F4 OPERATOR’S MANUAL

TENSIONING THE RECOIL SPRING

STARTER ROPE REPLACEMENT

MAINTENANCE

• Loosen the four screws that attach the starter cover

assembly to the crankcase, and remove the starter

cover assembly from the saw.

• Pull cord out from pulley approximately 12 inches (30

cm) and hook rope into the notch in the pulley. Relax

the recoil spring by placing thumb on the pulley and

gently allow the pulley to rotate backwards to unwind

the spring entirely.

• Remove the old starter rope. If necessary, the pulley

may be removed to extract old rope and then replaced

in the housing prior to installing new rope.

• Thread the new starter rope through the hole in the

starter housing and then through the hole in the pulley.

• Wrap the starter rope around the raised center of the

pulley, looping over top and under the beginning of the

wrap. Tighten the knot firmly and ensure that free end

of rope is as short as possible. Secure the other end of

the rope in the starter handle.

• 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.

CAUTION: Check that the pulley can be turned an additional 1/2 turn when the starter cord is

pulled all the way out.

TITLE 695GC / 695F4 OPERATOR’S MANUAL

CHAIN TENSIONER

The chain tensioner can become clogged with concrete

slurry during cutting. After each use thoroughly flush the chain

tensioner with water and apply a liberal amount of grease.

IMPORTANT

NOTE: The chain tensioner is located on side cover, to the outside

of the guidebar.

Most Common Causes of Tensioner Damage:

• Side cover nut is not tight enough. Side cover nut should be

torqued to 20-25 ft-lbs (27-33 Nm).

• Chain tensioning is attempted without loosening the side cover

nut.

• Concrete debris in tensioner pocket.

MAINTENANCE

STARTER HOUSING ASSEMBLY

• To reattach the starter cover assembly, first pull the starter

cord out, then hold the starter housing against the crankcase.

Slowly release the starter cord to enable the pulley to fit

between the pawls.

• Insert and tighten the screws. Use blue Loctite® #242.
