SAFETY

THE FOLLOWING WARNING SYMBOL APPLIES TO ALL THE ITEMS LISTED

ON THIS PAGE

This power cutter 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 power cutter immediately. If the

problem persists, seek medical attention.

WARNING Indicates a hazard with a medium level of risk

which, if not avoided, could result in death or

serious injury.

701-A SERIES OPERATOR’S MANUAL

• Always disconnect the air supply and relieve pressure from supply lines

before performing maintenance on the power cutter.

• Diamond chains and guidebar require a minimum water pressure of 20 psi

(1.4 bar). Insucient water supply may result in excessive wear to the

guidebar or diamond chain, which can lead to loss of strength and diamond

chain breakage and damage the bar.

• When operating a compressor with greater than 90 psi (6 bar) it is

recommended to use a “service unit with pressure regulator” in line to

prevent over speeding the power cutter.

GENERAL SAFETY PRECAUTIONS

• Always wear protective clothing, including a hard hat, eye protection, hearing

protection and gloves.

• Avoid loose clothing.

• Perform safety checks before starting each day.

• Always operate tool with solid footing and handgrip.

• Remove or control slurry to prevent yourself or others from slipping while

cutting.

• Always work in a cleared area.

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

• Set up a well-marked safety zone with a roped boundary and clear signs to

keep bystanders at least 20 ft (5m) away.

• Breathing exhaust fumes is dangerous. Provide ventilation in closed areas.

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

701-A SERIES OPERATOR’S MANUAL

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, more power

goes into turning the chain rather

than into the cut. In extreme

over-tightened cases, the power

cutter 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.

PRE-CUT CHECKLIST

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 sure to wear gloves. 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.

PROPER CHAIN TENSION

Concrete cutting power cutters operate with looser chain tension than wood

chainsaws. It is common, especially on gas powered, concrete cutting

power cutters to have the drive links hang completely out of the bar. Concrete

cutting power cutters require water for cooling and flushing the cut. Rotating

the chain completely around the bar freely by hand will let you know you have

the chain properly tensioned.

Before tensioning chain, always turn the compressor off and relieve system

pressure before disconnecting from the compressor.

To maximize the life of the cutting system, ensure that proper chain

tension is maintained.

If tension is too tight, it will lead to excessive chain stretch, and a lot of the

power cutters power will be used 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 off of the bar, or allow the sprocket to

turn with out turning the chain, which will damage the drive links.

WARNING

CAUTION

701-A SERIES OPERATOR’S MANUAL

PRE-CUT CHECKLIST, CONT.

• Adequate Water Supply and Pressure:

Minimum Flow: 1 gpm (4 lpm)

Minimum Water Pressure: 20 psi (1.4 bar)

Checking for water pressure without a pressure gauge: With the compressor

o, attach water hose to the power cutter water connection. Pull the chain

o to one side of the bar and turn on the water valve. If there is a minimum of

20 psi, water should spray 1 - 3 ft (.3 to 1 m) from the bar.

• Proper Air Supply to the Power Cutter:

Allowable Air Pressure: 90 (6 bar) maximum

Air Supply Requirement @ 90psi (6 bar): 124 cfm (3.5 M3/min) minimum

Insure the air supply line is clear before connecting it to the power cutter.

Dirt and water separators are recommended to prevent rust and

condensation from forming in the air lines.

• Motor Lubricator: (Not Included)

Always use an in-line oiler to provide continuous lubrication to the air

motor. The air lubricator or combination lubricator/air drier must be placed 6

to 12 feet (2 - 4 meters) from the tool. This will increase the life of the power

cutter and reduce down time.

Check oil level, when necessary; ll with resin and acid-free SAE 5 W to

SAE 10 W oil.

In winter or when using very moist air, use antifreeze lubricant, such as “ICS

Prolube ATL/AF”, “Killfrost” “BP Energol AX10” or “Kompranol”

OPERATION

701-A SERIES OPERATOR’S MANUAL

PLANNING THE CUT

• Select the proper chain for the material being cut.

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

• Avoid pinching the bar and chain. Always cut the bottom of an opening rst,

then top, and then the sides. Save the easiest cut for last.

OPERATION

If cutting pipe with PowerGrit® be sure the cut line stays open by providing

proper pipe support. Also check for neighboring utilities or obstructions.

Concrete is very heavy, 1 cubic foot (30 cubic cm) weighs 150 lbs (68 kg). Be

sure to cut so that concrete cannot fall and injure operator or bystanders.

Check for live electrical wiring near the cutting area or in the concrete to

avoid electrocution which can result in death or serious personal injury.

WARNING

• When cutting reinforced concrete, be sure you are always cutting

concrete as well as rebar. This will prevent the segments from glazing

over and keep the diamonds exposed. Also, expect less chain life when

cutting concrete with heavy rebar.

• When replacing a chain, ip the guidebar over and dress your

guidebar rails to maintain straight cuts. Guidebar rails can be dressed

with a at le or belt sander.

• Note: The normal life of a guidebar is 2 to 3 chains. However, heavy

rebar can shorten guidebar life too.

• When using a new chain, cutting speed can be increased by

“opening up the diamonds”. Make a few plunge cuts in an abrasive

material such as a cinder block.

Wear gloves when handling the bar and chain. Over time, these components

can develop sharp edges and cause cuts.
