HANDLING HYDRAULIC FLUID SAFELY

WARNING

Hydraulic uid is combustible or can become combustible.

Consult the SDS (Safety Data Sheet) for the hydraulic uid being used for ash point and auto ignition temperature ranges. When these uids discharge under pressure in a ne mist, they ignite easily, burn rapidly, and emit large quantities of heat. In fact, their heats of combustion, which are over 18,000 BTU/lb (2327 kJ/kg), are comparable to fuel oil.

CAUTION

Check for hydraulic leaks before starting the hydraulic power source.

Visually check for leaks from the hydraulic ttings, and lines and do not use if

any leaks are found.

WORK AREA SAFETY

Following are the basic instructions for work area safety.

WARNING

Drugs or alcohol can impair vision, dexterity, and judgment.

Do not operate the power cutter when tired or under the inuence of any substance.

Do not operate this product during severe inclement weather.

CAUTION

Remove or control slurry to prevent slippery conditions while cutting. This power cutter uses water and can cause slippery surfaces due to the slurry

produced and/or freezing temperatures.

Keep 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.

WARNING

ENGLISH

Fluids escaping under pressure can penetrate skin and cause severe personal injury.

Do not use hands to search for leaks. Before disconnecting lines, be sure to relieve all pressure. Do not apply pressure to damaged lines, hoses or ttings. If any uid is injected into the skin, seek medical attention immediately to prevent gangrene. Consult supplied hydraulic uid SDS for additional

information regarding proper handling and use instructions.

Long-term exposure to noise can result in permanent hearing impairment.

Always wear approved hearing protection.

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 recommended water pressure to minimize dust generation.

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.

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.

CHAIN TOO TIGHT CHAIN TOO LOOSE

890F4 OPERATOR MANUAL

Unpacking & Assembly

CHECKING & ADJUSTING 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.

WARNING

Improper chain tension can lead to breakage 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.

IMPORTANT

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.

A tight chain may rob power reducing cutting performance and increasing

chain friction, resulting in chain stretch. 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.

CONNECTING TO HYDRAULIC SUPPLY

Assure hydraulic hoses are connected to power cutter with the proper ow direction. The chain should travel away from the operator on the top of the bar and return on the bottom of the bar. If hydraulic motor does not turn when trigger is depressed, this may be an indication that the hydraulic ow direction

is likely reversed. Refer to diagram on page 13 for more details.

Unpacking & Assembly

890F4 OPERATOR MANUAL

CONNECT TO WATER SUPPLY

Following are the basic instructions for correct water supply to the

power cutter.

CAUTION

ENGLISH

Insucient water supply will result in excessive chain stretch and may

cause chain breakage, damage to the guidebar, nose sprocket and drive sprocket.

Never operate the power cutter with insucient water supply. In all cases, assure that the water supply is delivering 1.5 bar (20 psi) pressure to the power cutter at a minimum ow rate of 4 lpm (1gpm).

Inadequate water can result in increased potential for harmful airborne particulates.

ICS® power cutters require a continuous water supply to the guidebar and chain for the key purposes of cooling, lubrication and dust suppression. The potential for airborne particulates depends on many factors including, but not limited to, the material being cut, application and cutting environment.

NOTE: Local and/or regional regulation can vary widely. It is the responsibility of the operator to wear appropriate dust protection applicable in their area and suitable to the application.

Attach to water supply capable of delivering 1.5 bar (20 psi) pressure to the power cutter at a minimum flow rate of 2 gpm/8 lpm. The single

most important factor an operator can control to increase chain life is to use adequate water pressure.

Operation

PRECUT CHECKLIST

WARNING

Be sure that no part of the cutting system is contacting a solid object when starting the power cutter.

The power cutter may react unexpectedly if the chain contacts a solid object.

WARNING

Sudden contact of the guidebar nose with a foreign object may generate kickback.

Remove and/or avoid any obstructions (plumbing, water supply hoses, electrical conduit, air ducts, etc.) that may interfere with the cut.

To avoid electrocution, check for live electrical wires.

Wires may be hidden within or behind walls and/or laying around the workspace. Assure that any ancillary electrical equipment (fans, pumps, vacuums, etc.) are properly grounded and certied for use in the intended

environment.

Always operate the power cutter with solid footing and both hands on the power cutter.

Keep your left hand on the front handle and your right hand on the rear handle. Wrap your thumbs around the handles to assure you maintain a secure grip on both handles.

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, steel toed shoes and a

respirator may also be required. Avoid loose tting clothing. Follow all local regulations regarding PPE.

Cutting with the power cutter may generate sparks, especially when cut-

ting through metal (such as rebar), and may start a re in combustible

materials such as dry grass, wood and fuel.

CUTTING WITH THE POWER CUTTER

WARNING

DO NOT insert the guidebar into a slot narrower than the width of the chain.

ENGLISH

Rapid pushback, kickback and/or chain breakage could result.

Be sure cut concrete cannot fall and injure the operator or bystanders.

Assure cut piece is controlled and does not fall unexpectedly.

NOTE: Concrete is very heavy; one cubic foot = 30 cm x 30 cm x 30 cm = 68 kg (12 in x 12 in x 12 in = 150 lbs).

CAUTION

Slippery or unstable surfaces such as ladders may cause a loss of balance or control of the power cutter.

Always keep proper footing and operate the power cutter only when standing on xed, secure and level surface.

Unexpected loss of control of the power cutter and loss of balance can result in injury.

Do not overreach and do not cut above shoulder height.

Do not allow workpiece to pinch the guidebar and chain, or rapid pushback could result.

Always cut bottom of opening rst and assure workpiece is secure and does

not shift during cutting operations. Do not operate power cutter upside down.

Cutting debris can be directed back towards the operator.

Take special precautions when cutting in horizontal orientation.

Be aware that debris may be ejected dierently than when cutting in a vertical

position.

IMPORTANT

CUTTING TIPS

• 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 guidebar.

• Next, deepen the cut by about two inches

• Then plunge all the way through and complete the cut using the

WallWalker® as a pivot point and pull on the rear handle to rotate the bar into the cut.

• When the WallWalker is extended in the mechanical mode, the Wall Walker provides a 4:1 mechanical advantage.

• Always operate the concrete power cutter at full throttle. If too much force is applied, the power cutter will lug or stall. The chain will not have enough

speed to cut eectively. If too little feed force is applied, the diamonds will

skid and glaze over.

• 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.

• When cutting heavy rebar, slowly “rock” the power cutter 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 extende periods of time, as the chain does not have a chance to “throw” the slurry away from the nose of the guidebar (use step cut method).

• If the power cutter begins to cut consistently crooked, stop the power cutter, remove the bar and chain and turn the bar over and use the other side. Dress worn rails with a belt sander, at le or bar rail dresser.

Note: The normal life of a guidebar is two to three diamond chains (with rotation after every chain). Heavy rebar can shorten guidebar life.

• The guidebar is solely a guide track for the chain. Never use the guidebar to lift, twist or pry concrete material.

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

“opening up the diamonds”. This can be accomplished by rst making a few cuts in an abrasive material such as a cinder block or brick.

PIPE CUTTING USING POWERGRIT® UTILITY CHAIN

To assure the best performance from your ICS® power cutter when cutting

ductile iron pipe or similar pipe materials, follow all safety precautions and recommended cutting techniques.

ENGLISH

WARNING

Never attempt to cut ductile iron pipe or similar pipe materials with the power cutter unless using PowerGrit® Utility Chain.

Using concrete diamond chain in these applications can cause the chain to snag abruptly in the cut which may result in chain breakage, pushback and/or kickback.

Always assure that pipe is properly evacuated before cutting.

Pipes may contain sewage, gas or other hazardous materials.

Always support the pipe on both sides of the cut to assure the cut remains

open throughout the cutting operation, including when the cut is nished.

An improperly supported pipe can cause the cut to close, pinching the chain and guidebar which may result in chain breakage, pushback and/or kickback.

Recommended Pipe Cutting Techniques

1. Make a small plunge cut into the lower quadrant

of the pipe to relieve internal pressure and allow contents to drain from pipe in a controlled manner.

2. With pipe drained, cut from the top of pipe and continue through bottom of the pipe.

3. To assure straightness of cut, guidebar should extend completely through the pipe during the cut.

4. To assist with cutting, engage the WallWalker® in the cut when possible to provide additional leverage and alternate cutting between the near

and far side walls of the pipe.

MAINTENANCE

IMPORTANT

SYSTEM CLEAN-UP

• After cutting, run the power cutter for at least 15 seconds with the water on to flush slurry and debris from diamond chain, guidebar and drive sprocket.

• Wash concrete slurry and debris from power cutter assembly.

• Remove guidebar and chain. Flush out the chain tensioner and side cover with water. Lubricate tensioner with waterproof grease.

• After cleaning the power cutter, spray the entire power cutter body, chain, guidebar, and drive sprocket with lightweight oil. Using lightweight oil on the power cutter will minimize rust and help reduce slurry build up.

AFTER EACH USE

• Inspect drive sprocket for wear

• Inspect and tighten all fasteners as necessary.

• Flush and rinse the power cutter, guidebar and chain with water

• Check trigger function assembly

• Check mud ap for tears or damage

• Check guidebar and chain for damage or missing segments

• Check trigger cover bubble levels

• With power cutter disconnected from power source, check hose whips for leaks or damage.

• Inspect drive sprocket for wear.

• Replace when the drive teeth are worn more than half way through.

DRIVE SPROCKET

Drive teeth

• The drive sprocket is a wear item and

should be replaced every two to three chains, or when the teeth become pointed

ENGLISH

or if a groove cuts through top of tooth.

• Inspect the sprocket for wear.

• Inspect drive shaft for wear.

Snap Ring

DRIVE SPROCKET ASSEMBLY REMOVAL/INSTALLATION

• Disconnect power cutter from the power source

• Remove the side cover, bar retainer plate,

guidebar and diamond chain

• Remove snap ring from shaft

• Slide drive sprocket off shaft

• Slide new sprocket onto shaft

• Replace snap ring onto shaft and assure complete engagement in shaft groove

• Installation of new drive sprocket is complete.

• Reinstall guidebar, diamond chain, bar retainer plate and side cover.

• Assure diamond chain and guidebar are in good, useable condition. Worn

or damaged guidebar and chain can damage the new drive sprocket.

CHAINS & GUIDEBARS

IMPORTANT

Inspect chain segments and drive links for damage or excessive wear. Chains with damage or excessive wear should not be used or repaired, they should be

replaced.

NOTE: Guidebars are designed to be used on both sides. If the cut is consistently leading to one side, turn the guidebar over. It is recommended to turn the guidebar over with every new chain.

• A table mounted belt, disc sander, at le or bar rail dressercan be used to square the rails of a worn guidebar. A badly worn guidebar can quickly damage the chain. If the chain is touching the bottom of the guidebar groove, replace the guidebar.

• Check the guidebar for straightness.

• Proper chain tension will extend guidebar life.

• Under some circumstances, especially low water pressure, the sprocket nose

can wear out before the guidebar body. Sprocket nose assemblies may be replaced by an Authorized Service Center.

• Periodically clean the water ports inside the groove of the guidebar using a small diameter piece of wire or pipe cleaner.

• The guidebar is solely a guide track for the chain. Never use the guidebar to lift, twist or pry concrete material.

• Prior to storage, spray the chain and guidebar with lightweight oil.

CHAIN TENSIONER

The chain tensioner can become clogged with concrete slurry during cutting.

• After each use thoroughly ush the chain tensioner with water and apply a liberal amount of waterproof grease covering the chain tensioner screw.
