GENERAL POWER TOOL SAFETY WARNINGS

WARNING READ ALL SAFETY WARNINGS AND ALL INSTRUCTIONS. Failure

to follow the warnings and instructions may result in electric shock, ﬁ re and/or serious injury. Save all warnings and instructions for future reference. The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

• Keep work area clean and well lit. Cluttered or

WORK AREA SAFETY

dark areas invite accidents.

• Do not operate power tools in explosive atmospheres, such as in the presence of ﬂ ammable liquids, gases or dust. Power tools create sparks

which may ignite the dust or fumes.

• Keep children and bystanders away while operating a power tool. Distractions can cause

you to lose control.

ELECTRICAL SAFETY

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodiﬁ ed plugs and matching outlets will

reduce risk of electric shock.

• Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric

shock if your body is earthed or grounded.

• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase

the risk of electric shock.

• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords

increase the risk of electric shock.

• When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use

of a cord suitable for outdoor use reduces the risk of electric shock.

• If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces

the risk of electric shock.

PERSONAL SAFETY

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the inﬂ uence of drugs, alcohol or medication. A

moment of inattention while operating power tools may result in serious personal injury.

• Use personal protective equipment. Always wear eye protection. Protective equipment such

as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with

your ﬁ nger on the switch or energising power tools that have the switch on invites accidents.

• Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left

attached to a rotating part of the power tool may result in personal injury.

• Do not overreach. Keep proper footing and

balance at all times. This enables better control

of the power tool in unexpected situations.

• Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewel- lery or long hair can be caught in moving parts.

• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of

dust collection can reduce dust-related hazards.

POWER TOOL USE AND CARE

• Do not force the power tool. Use the correct power tool for your application. The correct

power tool will do the job better and safer at the rate for which it was designed.

• Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be

controlled with the switch is dangerous and must be repaired.

• Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such pre-

ventive safety measures reduce the risk of starting the power tool accidentally.

• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the

hands of untrained users.

• Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents

are caused by poorly maintained power tools.

• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

• Use the power tool, accessories and tool bits etc., in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool

for operations different from those intended could result in a hazardous situation.

SERVICE

• Have your power tool serviced by a qualiﬁ ed repair person using only identical replacement parts. This will ensure that the safety of the power

tool is maintained.

SPECIFIC SAFETY RULES

•Diamond coring equipment requires the use of water. When drilling overhead, use a liquid collection system. Water in contact with the elec-

trical system of the tool may make exposed metal parts of the tool "live" and could give the operator an electric shock.

•Operate power tool by insulated grasping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a

"live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.

•Wear ear protectors when diamond drilling.

Exposure to noise can cause hearing loss.

•When the bit is jammed, stop applying downward pressure and turn off the tool. Investigate

and take corrective actions to eliminate the cause of the bit jamming.

•When restarting a diamond drill in the workpiece check that bit rotates freely before starting. If the bit is jammed, it may not start, may

overload the tool, or may cause the diamond drill to release from the workpiece.

•When securing the drill stand with anchors and fasteners to the workpiece, ensure that the anchoring used is capable of holding and restraining the machine during use. If the workpiece is

weak or porous, the anchor may pull out causing the drill stand to release from the workpiece.

•When securing the drill stand with a vacuum pad to the workpiece, install the pad on a smooth, clean, non-porous surface. Do not secure to laminated surfaces such as tiles and composite coating. If the workpiece is not

smooth, ﬂ at or well afﬁ xed, the pad may pull away from the workpiece.

•Ensure there is sufﬁ cient vacuum level before drilling. If the vacuum level is insufﬁ cient, the pad

may release from the workpiece.

•Never perform overhead drilling with the machine secured only by the vacuum pad. If

the vacuum is lost, the pad will release from the workpiece.

•When drilling through walls or ceilings, ensure to protect persons and the work area on the other side. The bit may extend through the hole

or the core may fall out on the other side.

•Always use a liquid collection system when drilling overhead. Water in contact with an elec-

trical system of the tool may make exposed metal parts of the tool "live" and could give the operator an electric shock.

•Maintain tools carefully. Keep handles dry , clean and free from oil and grease. Keep cutting edges sharp and clean. Follow instructions for lubricating and changing accessories. Periodically inspect tool cords and extension cords for damage. Have damaged parts repaired or replaced by a MILWAUKEE service facility.

• Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a free replacement.

• WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• lead from lead-based paint

• crystalline silica from bricks and cement and

other masonry products, and

• arsenic and chromium from chemically-treated

lumber. Your risk from these exposures varies, depending

on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to ﬁ lter out microscopic particles.

EXTENSION CORDS

Grounded tools require a three wire extension cord. Double insulated tools can use either a two or three wire extension cord. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. Refer to the table shown to determine the required minimum wire size. The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord. When using more than one extension cord to make up the total length, be sure each cord contains at least the minimum wire size required. If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum wire size.

Guidelines for Using Extension Cords

• If you are using an extension cord outdoors, be sure it is marked with the sufﬁ x “W-A” (“W” in Canada) to indicate that it is acceptable for outdoor use.

• Be sure your extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualiﬁ ed person before using it.

• Protect your extension cords from sharp objects, excessive heat and damp or wet areas.

INSTRUCTIONS FOR FUTURE USE.

WARNING Improperly connecting the

grounding wire can result in the risk of electric shock. Check with a qualiﬁ ed electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the cord or plug is damaged. If damaged, have it repaired by a MILWAUKEE service facility before use. If the plug will not ﬁ t the outlet, have a proper outlet installed by a qualiﬁ ed electrician.

MILWAUKEE Dymodrills are provided with a 20 amp locking plug (NEMA L5-20). MILWAUKEE meter boxes may be provided with either a 20 amp locking or a 30 amp (NEMA L5-30) locking plug depending on the model .

Grounded Tools: Tools with Three Prong Plugs

Tools marked “Grounding Required” have a three wire cord and three prong grounding plug. The plug must be connected to a properly grounded outlet (See

Fig. A

Figures A and B). If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user, reducing the risk of electric shock.

Fig. B

The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool. The green wire in the cord must be the only wire connected to the tool's grounding system and must never be attached to an electrically “live” terminal. Y our tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in Figures A and B.

Double Insulated Tools: Tools with Two Prong Plugs

Tools marked “Double Insulated” do not require grounding. They have a special double insulation system which satisfies OSHA requirements and complies with the applicable standards of Underwriters Laboratories, Inc., the

Fig. C

Fig. D

Canadian Standard Association and the National Electrical Code. Double Insulated tools may be used in either of the 120 volt outlets shown in Figures C and D.

WARNING To reduce the risk of injury,

always use a Ground Fault Circuit Interrupter (GFCI) with diamond coring equipment to reduce the risk of shock hazards. Always position the GFCI as close as possible to the power source.

Methods for Securing Equipment to Work Surface

WARNING

always secure the rig to the work surface to help prevent personal injury and to protect the rig. An unsecured rig could rotate during coring and possibly cause injury.

NOTE: Some building materials contain steel

reinforcements. MILWAUKEE Dymobits can cut through embedded steel, but are not recommended for coring solid steel plates.

Horizontal Coring (walls)

For speciﬁ c instructions on using anchors, see "Using an Expansion-Type Anchor".

To reduce the risk of injury

WARNING To reduce the risk of injury

always use an expansion-type anchor during horizontal coring. Vacuum systems can slip when used on a vertical surface.

Vertical Coring (ﬂ oors)

Two methods will work to secure the rig for vertical coring: either an expansion-type anchor OR a vacuum pump and vacuum pad system. Securing the rig with an anchor gives better bit performance because the attachment is more rigid. For speciﬁ c instructions on assembling the vacuum system, see "Assembling and Using a Vacuum System".

Optional Telescoping Assembly

The telescoping assembly can be used to supplement either securing method. NOTE: Vac-U-Rig® Cat. No. 4136 includes a vacuum pump and vacuum pad. However, for some applications, you may choose to use an expansiontype anchor to secure the tool. Anchors and T elescoping Assembly are not supplied with any of the above rigs. Telescoping Assembly can be purchased separately (see “Accessories”). Anchors unavailable through MILWAUKEE.

2. Place the top ﬂ ange of the extension against a ceiling or wall and place the other end on the jack screw at the top of the Dymorig column.

The assembly is adjustable up to 14 feet. Turn

the jack screw to tighten the assembly and to make small adjustments.

Supply an Adequate Water Flow

An adequate supply of water must ﬂ ow freely and constantly during the entire cut. Dymodrills are equipped with a built-in water shut-off valve to allow water to ﬂ ow down the inside and up around the outside of the bit. This acts to cool the bit and ﬂ ush cuttings from the hole.

Reading the Meter Box

The ammeter is the dial indicator on the meter box, which is standard equipment with the Vac-U-Rig® and can be purchased separately for other Dymorigs. The ammeter provides pressure feedback during coring, allowing you to help prevent motor overload and premature bit wear. The green area on the ammeter is the operating range and the red area indicates that you are applying too much pressure.

WARNING To reduce the risk of injury ,

always use Dymodrills in conjunction with meter boxes. Meter Boxes provide a switch to turn the Dymodrill motor OFF and ON and an optimum operation range to help prevent motor overload.

Shear Pin and Clutch

Dymodrill Nos. 4079, 4090, and 4094 contain a shear pin to protect the gear and motor against overload. This pin drives the spindle sleeve. If the bit binds, the pin will shear to prevent gear and motor damage. Extra shear pins are supplied with each Dymodrill and can be replaced (see "Accessories" for part numbers). It is important to check the condition of the spindle before using the tool each

time. The spindle must be smooth without grooves or pitting. If the spindle is not in good condition, it is possible for the threaded spindle sleeve and the internal spindle to weld together and seize during coring (see "Lubricating the Spindle for Dymodrills with a Shear Pin" in the "Maintenance" section for spindle lubricating instructions).

Cat. Nos. 4004, 4005, 4096 and 4097 feature a friction clutch rather than a shear pin to protect the motor and gears. If the motor overloads, the clutch will begin to slip and the bit will stop rotating. The clutch is factory-set and does not require adjustment. Nuisance (frequent) clutch slippage should be addressed by an authorized MILWAUKEE service center.

WARNING T o reduce the risk of injury,

always check the work area for hidden wires before coring.

Coring Procedure

1. Select and install a bit following guidelines in "Selecting and Installing a Core Bit".

2. Secure the rig to the work surface using one of the methods described in "Methods for Securing Equipment to Work Surface".

3. With the motor OFF, adjust the gear to either high or low speed according to the guidelines in "Selecting Speeds".

NOTE: DO NOT SHIFT SPEEDS WHEN THE

DYMODRILL MOTOR IS ON. To adjust the

speed on all Dymodrills, move the gear shift lever to the desired setting.

Water Shut-Off Valve

4. Connect the water hose to the Dymodrill water shut-off valve and to the water supply. Make sure the seal is watertight. Use a standard garden hose if you require additional length. Set up a water collection system.

5. If you are using a vacuum system, read the instructions for speciﬁ c setup in "Assembling & Using a Vacuum System".

Do not continue the following steps until the

vacuum gauge reads at least 20 inches of mercury vacuum. Never operate the Dymodrill if the gauge reads less than 20 inches (see "Mothods for Securing Equipment to Work Surface"). Always monitor the vacuum gauge during coring. If water collects in the vacuum pump ﬁ lter jar, empty it to prevent damage to the pump.

WARNING T o reduce the risk of injury,

do not operate the Dymorig if the gauge reads less than 20 inches of mercury vacuum.

6. Turn the Dymodrill motor ON. Turn the water on so it ﬂ ows freely through the water shut-off valve (see "Supply an Adequate Water Flow"). Turn the valve clockwise to increase water ﬂ ow and counterclockwise to decrease water ﬂ ow.

7. While holding the handle, slightly loosen the cradle lock handle and slowly rotate the handle to lower the bit into the workpiece, applying steady, even pressure. To help reduce bit wandering, always use a light load to start the hole and wait for the tip of the bit to penetrate the work surface completely before increasing the load.

8. Use sufﬁ cient pressure so the bit cuts constantly. Use the ammeter on the meter box as a guide for proper pressure.

NOTE: If the rig shifts during coring, stop the

motor, reposition the rig and resume coring.

9. Monitor the water ﬂ ow (see "Diamond Coring"). Generally, water should ﬂ ow at a rate of ap- proximately one to two gallons per minute. If the water ﬂ ow is too heavy, the two holes in the water swivel housing will leak. If that happens, reduce water ﬂ ow. W ater ﬂ ow is adequate when the water and cuttings are ﬂ ushed in a circular pattern about 1/2" around the bit. Keep the work area dry.

10.When the cut is complete, keep the drill motor ON and rotate the handle clockwise to remove the bit. The bit may become stuck in the hole if you turn the motor OFF before the bit is completely removed. Once the bit is removed from the work surface, turn the motor OFF . T ighten the cradle lock handle. Unplug the meter box from the power supply before removing the vacuum pump to prevent accidental starting of the motor when the vacuum pump is released.

If you are using a vacuum pump, unplug it and

open the vacuum release valve to release the vacuum.

Retrieving Cores and Deep Coring

When coring holes that are longer than the core bit, follow the steps below.

1. Begin coring the hole as usual. When you have cored to the length of the bit, stop the Dymodrill motor.

2. Remove the core by driving a chisel or slender wedge into the cut between the core and the work surface. Y ou may also use a special core tongs, bent wire or anchor bolts to remove the core.

3. After removing the core, reinsert the bit or use a bit extension and continue coring (see "Accessories"). Removing cores with diameters greater than twice their length can be difficult. One method to remove such cores is to ﬁ rst break the core into smaller pieces and then remove the pieces. Electric hammers and chisels are ideal for breaking cores.

WARNING When coring through ﬂ oors,

cores generally drop from the bit. To reduce the risk of injury, provide proper protection for people and property below the coring area.

Diamond Coring

Factors that inﬂ uence diamond core performance:

• Amount of coolant

• Dymorig rigidity

• Dymorig condition

• RPM of drill motor

• Feed pressure applied to bit by operator

• Amount of steel

• Size of embedded steel

• Age of concrete

• Aggregate (size, type, hardness, abrasiveness)

• Type of sand–manufactured vs. river (natural)

• Operator technique

• Operator care

• Bit runout

Operator Technique

Core with consistent, ﬁ rm feed pressure. Do not subject the bits to sudden impacts. Uneven feed rate cracks diamonds. Low feed pressure polishes diamonds, slows penetration and contributes to bit glazing. High feed pressure can overload the drill motor or can cause diamonds to pull out prematurely, particularly when coring embedded steel. Make the bit work, but do not try to jam the bit through the material. If vibration occurs:

1. Stop drilling.

2. Turn motor off.

3. Check for loose bolts, nuts and gib screws. Tighten if required.

4. Check for bit runout. Replace if required.

If vibration continues to occur, remove the core and loose material. If vibration continues to occur after attempting these measures, return the rig to the nearest MILWAU- KEE service facility.

Water

Water provides two main beneﬁ ts during coring:

1. Water acts as a coolant, eliminating the heat caused by the friction of the coring action. This preserves the integrity of the diamonds, the bond matrix, the segment solder, and core tube. Without a coolant, the heat buildup during coring can cause all of these components to fail.

2. Water ﬂ ushes loose, abrasive particles created during coring. These particles consist of aggregate, sand, diamond particles and various metals from embedded steel and the core bit matrix. The hole must be free of debris to allow the core bit to work. If loose particles are not properly ﬂ ushed from the hole, an unnecessary

drag will occur along the side of the core barrel. This can contribute to bit glazing through lack of power as well as motor damage through amperage increases due to bit resistance. In addition, loose particles tend to wear the bit tube, which

can eventually result in the loss of segments. Monitor water ﬂ ow. Water volume should be ad- justed until water return is a muddy, solid color. Clear water or clear streaks indicate too much water volume. Excess water is a leading cause of bit glazing and failure. Other factors contribute to glazing, but water adjustment is one of the most easily controlled by the operator. Excessive water prevents adequate segment/material contact. When the bit segments do not properly contact the work surface, the desired "controlled erosion" effect which maintains bit sharpness does not occur and the bit begins to glaze. This happens especially with smaller diameter bits. Adequate water volume varies according to the bit diameter. Use only enough water during coring to ﬂ ush the cuttings from the work surface.

Equipment

• Make sure machinery is in good operating condi-

tion. The column, carriage, motor connection and base should all be ﬁ rmly connected and should not vibrate during coring.

• Motors should be of proper size (amperage and

RPM) for the diameter of the core bit used. Consult motor guide in catalog.

• Always make sure the Dymorig is rigidly mounted

with an anchor or vacuum; any movement or vibration will shorten the life of the core bit. Standing on the rig's base as a form of anchoring is dangerous and does not provide the necessary rigidity.

Diamond Core Bits

• For the ﬁ rst 2 or 3 holes, use light feed pressure,

so the new diamond gradually breaks in.

• Lower the bit very slowly onto the work surface.

Use light feed pressure until the bit crown has penetrated or "seated" into the material.

• If the core bit encounters embedded steel, slow

down the feed pressure and let the bit core at its own pace. Don't force the bit. Typically the water around the bit will clear when embedded steel is encountered. Do not allow any vibration whatsoever or severe diamond breakage or pullout will occur.

• Keep bits sharp.

Bit Glazing & Diamond Core Motor Shear Pins

Bit binding is caused by one of two things: a dull (glazed) bit or a poorly stabilized rig. Causes of bit glazing:

• Wrong RPM for bit diameter

• High feed pressure

• Low feed pressure

• High steel content in work surface

• Large, hard aggregate

• Too much water

• Low motor power A sharp bit typically has good diamond exposure and will cut/grind almost anything in its path, including embedded steel.

Sharpening Procedure for Core Bits

To work efﬁ ciently, diamond core bits must main- tain good diamond exposure. Many factors work together to provide the "controlled erosion" cycle of the tool's segment to occur. When this "controlled erosion" cycle is altered, the bit can become dull or "glazed." Glazing becomes noticeable when the coring feed rate slows dramatically or the bit does not cut. Examine the bit immediately. If the diamonds are ﬂ ush with the metal, they are under- exposed or "glazed." The following steps will often correct the problem:

1. Reduce water ﬂ ow until it becomes very muddy. Continue using as little water as possible until penetration increases.

2. If the bit does not open up, remove from hole. Pour into the kerf a thick (1/4") layer of silica sand (the coarser the better).

3. Resume drilling for approximately 3 to 5 minutes with very little water and at a lower RPM if possible.

4. Gradually increase water ﬂ ow to ﬂ ush sand from kerf.

5. Repeat as needed.

The Effects of Steel in Coring

• To self-sharpen, diamond-impregnated core bits

require interaction with an abrasive material. This abrasive material wears away the metal composition in the segment's matrix. As this is done, sharp diamonds are exposed and the grinding action created by the diamonds continues.

• Embedded metal (rebar) is not an abrasive mate-

rial. It does not provide the degree of abrasiveness required for matrix wear to occur and expose sharp diamonds embedded in the segment's matrix.

• A high degree of exposure to embedded metal

by the bit's segments creates glazing. Glazing prevents the bit from cutting and coring.

Keep your tool in good repair by adopting a regular maintenance program. Before use, examine the general condition of your tool. Inspect guards, switches, tool cord set and extension cord for damage. Check for loose screws, misalignment, binding of moving parts, improper mounting, broken parts and any other condition that may affect its safe operation. If abnormal noise or vibration occurs, turn the tool off immediately and have the problem corrected before further use. Do not use a damaged tool. Tag damaged tools “DO NOT USE” until repaired (see “Repairs”). Under normal conditions, relubrication is not necessary until the motor brushes need to be replaced. After six months to one year, depending on use, return your tool to the nearest MILWAUKEE service facility for the following:

• Lubrication

• Brush inspection and replacement

• Mechanical inspection and cleaning (gears, spindles, bearings, housing, etc.)

• Electrical inspection (switch, cord, armature, etc.)

• T esting to assure proper mechanical and electrical operation

Lubricating Rack and Pinion

Maintain a light coat of MILWAUKEE Type "E" Grease on the rack and pinion gears to reduce friction and wear.

Lubricating the Spindle for Dymodrills with a Shear Pin

Before each use, clean and lubricate the spindle or spindle sleeve with MILWAUKEE T ype "E" Grease to prevent the spindle from seizing during coring.

1. To maintain the spindle on shear pin models,

remove the retaining ring with a screwdriver. Then remove the spindle sleeve.

2. Remove dust and debris from the inside and out-

side diameter of the spindle and spindle sleeve and from the water hole in the spindle. Place a light coating of MILWAUKEE T ype "E" grease on the spindle.

3. Replace the spindle sleeve onto the spindle.

Make sure the spindle sleeve rotates freely on the spindle. Then replace the retaining ring.

Replacing Vacuum Pad Gaskets

For Cat. No. 4115, 4125 & 4130 only. Through normal use, the rubber gaskets on the underside of the vacuum pads can become worn, requiring replacement. If replacement is required, take the pad to an authorized service center or replace the gasket as follows:

1. Remove the old gasket and thoroughly remove the old glue from the groove.

2. Squeeze a continuous bead of rubber cement (Cat. No. 44-22-0060) in the entire bottom of the groove.

3. Immediately place a new gasket (Cat. No. 4344-0570) in the groove and press ﬁ rmly in place.

4. Turn the pad over and place the gasket side on a smooth ﬂ at surface and apply pressure to all edges of the pad.

5. Allow cement to dry for 24 hours before using.
