RIDGID HC-450 Hole Cutting Tools

General Safety Rules

Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.

• Keep work area clean and well-lit. Cluttered benches and dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks that may ignite dust or fumes.
• Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control.
• Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user.
• Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is 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 to carry the tool or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.
• When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These cords are rated for outdoor use and reduce 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 tool while you are tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
• Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
• Avoid accidental starting. Be sure the switch is OFF before plugging in. Carrying power tools with your finger on the switch or plugging in power tools that have the switch ON invites accidents.
• Remove adjusting keys or wrenches before turning the tool ON. A wrench or a key left attached to a rotating -ing part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enable better control of the tool in unexpected situations.
• Use safety equipment. Always wear eye protection. Safety equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection used for appropriate conditions will reduce personal injuries.

Tool Use and Care

• Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.
• Do not force the tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate at which it was designed.
• Do not use the power tool if the switch does not turn it ON and OFF. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
• Store idle tools out of the reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
• Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edges are less likely to bind and are easier to control.
• Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.
• Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool.

Service

• Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.
• When servicing a tool, use only identical replace-ment parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of electrical shock or injury.

Hole Cutter Safety Warnings

• This section contains important safety information that is specific to this tool.
• Read these precautions carefully before using this Hole Cutting Tool to reduce the risk of electrical shock or another serious personal injury. Keep this manual with the machine for use by the operator.
• Always wear appropriate eye protection. Cutting tools can break or shatter. Cutting produces chips that can be thrown or fall into the eyes.
• Do not wear gloves or loose clothing when operating the machine. Keep Sleeves and jackets buttoned. Do not reach across the machine. Clothing can be caught by the machine resulting in entanglement.
• Keep fingers and hands away from rotating chuck and saw. This reduces the risk of entanglement and cutting injuries.
• Properly secure the Hole Cutting Tool to the pipe. Improperly secured Hole Cutting Tools can fall and cause striking and crushing injuries.
• Do not use for hot tapping. When cutting into an existing system, the pipe must be drained and de-pressurized prior to cutting. This reduces the risk of electrical shock and another serious injury.
• Before using, test the Ground Fault Circuit Interrupter (GFCI) provided with the power cord to insure it is operating properly. GFCI reduces the risk of electrical shock.
• When working overhead, all personnel should wear hard hats and be clear of the area below the tool. This reduces the risk of serious injury should objects fall.
• Only use Hole Cutting Tools to cut holes in the pipe as directed in this manual. Do not use it for other purposes or modify it. Other uses or modifying this tool for other purposes may increase the risk of serious injury.
• Read and understand the instructions and warnings for all equipment being used before operating the Hole Cutting Tool. Failure to follow all instructions and warnings may result in property damage or serious personal injury.

Machine And Work Area Set-Up

Set up the Hole Cutting Tool and work area according to these procedures to reduce the risk of injury from electrical shock, entanglement, crushing, and other causes and prevent tool damage.
Properly secure the Hole Cutting Tool to the pipe. Improperly secured Hole Cutting Tools can slip and fall and cause striking and crushing injuries. Do not use for hot tapping. When cutting into an existing system, the pipe must be drained and de-pressurized prior to cutting. This reduces the risk of electrical shock and other serious injuries. When working overhead, all personnel should wear hard hats and be clear of the area below. This reduces the risk of serious injury should equipment or other objects fall.

• Check work area for:
• Adequate lighting.
• Flammable liquids, vapors, or dust that may ignite. If present, do not work in the area until sources have been identified and corrected. The hole cutter is not explosion-proof and can cause sparks.
• Clear, level, stable, dry location for all of the equipment and operator.
• Properly grounded electrical outlet of the correct voltage. A three-prong or GFCI outlet may not be properly grounded. If in doubt, have the outlet inspected by a licensed electrician.
• Clear path to an electrical outlet that does not contain any potential sources of damage for the power cord.
•  Inspect the work to be done. Determine the pipe type and size, and clearance around the pipe. Determine the size and location of the hole to be cut. Clearly mark the cut location. If installing a fitting, follow the fitting manufacturer’s instructions. Determine the correct equipment for the job. See the Description and Speci -fi cation sections for tool information.
• Make sure that the pipe to be cut is well supported and stable. The pipe must be able to handle the weight of the Hole Cutting Tool and the forces applied during cutting without moving.
• If working on an existing system, make sure that the system has been depressurized and drained. The Hole Cutting Tools are not designed for hot tapping purposes. Cutting into pressurized or systems with flu-ids in them can cause spills, electrical shock, and another serious injury. Know the contents of the pipe and any specific hazards associated with the contents.
•  Confirm that the equipment to be used has been properly inspected,
•  Select an appropriate hole saw for the work to be performed. Make sure that the hole saw is properly as-sembled per its instructions and is in good working order. The use of a pilot drill is recommended. The pilot drill should extend no more than 3/8″ (10mm) past the end of the hole saw and should be securely tightened.
•  With the Hole Cutting Tool on a stable surface, install the hole saw into the chuck. Always make sure that the ON/OFF switch is in the OFF position and the Hole Cutting Tool is unplugged before installing or changing the hole saw or drill.
• Open the chuck wide enough for the shank of the hole saw. If needed, the chuck key can be used to open the chuck. Make sure that the shank and the chuck jaws are clean.
• Fully insert the shank into the chuck. Make sure that the hole saw is centered in the chuck and firmly tighten the chuck by hand.
• Use the chuck key in all three chuckholes to securely tighten the chuck onto the shank. Make sure to remove the chuck key from the chuck before turning the tool ON.

Mounting The Hole Cutting Tool On The Pipe

Hole Cutting Tools weigh up to approximately 42 pounds. Use good lifting technique when placing on the pipe, do not overreach, and keep good balance and footing at all times. Depending on the circumstances, two people may be necessary to mount the Hole Cutting Tool onto the pipe. Hole Cutting Tools can be used at any angle or orientation. If cutting a hole on the side or bottom of a pipe, it may be easier to place the Hole Cutting Tool on the top of the pipe to fasten the chain around the pipe and then move the Hole Cutting Tool into the final position.

HC-450

1.  Make sure the chain is hanging freely and the swivel handle is fully loosened.
2.  Carefully lift the HC-450 Hole Cutting Tool and place with the V-shaped guides squarely on the pipe near the location of the cut. Make sure the chain is not be-tween the pipe and tool base.
3.  Always keep at least one hand on the Hole Cutting Tool to stabilize and guide it. Grasp the end of the chain and pull it snugly around the pipe. Hook the closest chain pin on the wear plate and firmly tighten the swivel handle to hold the Hole Cutting Tool to the pipe. (See Figure 5)
4.  The base of the HC-450 Hole Cutting Tool includes a  level vial that can be used to align a series of holes. When the Hole Cutting Tool is placed at the desired angle, the vial can be rotated to the level position, and subsequent holes can be made at the same angle by leveling the Hole Cutting Tool with the vial.(See Figure 6)
5.  With one hand on the Hole Cutting Tool to stabilize and guide it, slightly loosen the swivel handle to allow final positioning of the tool. Align the pilot drill with the de-sired cut location, and firmly tighten the swivel handle. Do not remove your hands from the Hole Cutting Tool until you have confirmed that it is securely attached to the pipe. The Hole Cutting Tool must be securely and squarely attached to the pipe to help reduce the risk of hole saw jamming.

HC-300
The HC-300 can be mounted on the pipe either as a complete unit (similar to the HC-450) or by separating the base assembly from the tool, mounting the base to the pipe, and then installing the motor assembly to the base assembly.

1.  With the HC-300 Hole Cutting Tool on a stable, secure surface, pull the plunger on the back of the left post (Figure 7) and lift the motor assembly off of the base assembly.
2.  Make sure the chain is hanging freely and the swivel handle is fully loosened on the base assembly.
3.  Place the base assembly with the V-shaped guides squarely on the pipe near the location of the cut. Make sure the chain is not between the pipe and tool base.
4.  Always keep at least one hand on the base assembly to stabilize and guide it. Grasp the end of the chain and pull it snugly around the pipe. As you pull on the chain, a spring is compressed at the attachment end of the chain. Hook the closest chain pin on the chain hook
5. the spring tension will help keep the chain engaged with the chain hook. Firmly tighten the crank screw as-sembly to hold the base assembly to the pipe. (See Figure 8.)
6.  Carefully lift the motor assembly and align the post openings in the motor assembly with the posts of the base assembly. Press the motor assembly on until the plunger engages the post to retain the motor as-sembly to the base. Confirm that the motor assembly is securely attached to the base. See Figure 9.
7.  The base of the HC-300 includes several machined flats for use with levels for hole alignment. See Figure 10.
8.  With one hand on the Hole Cutting Tool to stabilize and guide it, slightly loosen the crank screw assembly to allow final positioning of the tool. Align the pilot drill with the desired cut location, and firmly tighten the crank screw assembly. Do not remove your hands from the Hole Cutting Tool until you have confirmed that it is securely attached to the pipe. The Hole Cutting Tool must be securely and squarely attached to the pipe to help reduce the risk of hole saw jam-ming.
9. To mount the HC-300 on the pipe as a complete unit, fol-low the steps indicated in the HC-450 section, using the information in the HC-300 section on chain hooking and alignment.

Powering the Hole Cutting ToolPowering the Hole Cutting Tool

1.  Confirm that the ON/OFF switch is in the OFF position.
2.  Makes sure that the power cord is routed out the back of the tool away from the chuck and work area. Run the cord along the clear path to the outlet, and with dry hand plug in. Keep all connections dry and off the ground. If the power cord is not long enough, use an extension cord that:
3. Is in good condition
4. Has a three prong plug similar to that on the tool.
5. Is rated for outdoor use and contains a W or W-A in the cord designation (i.e. SOW), or complies with H05VV-F, H05RN-F types or IEC type design (60227 IEC 53, 60245 IEC 57).
6. Has sufficient wire size (16 AWG (1.5mm2) for 50′ (15.2m) or less, 14 AWG (2.5mm2) for 50′ – 100′ (15.2m – 30.5m) long). Undersized wires can overheat, melting the insulation or causing a fire or other damage. When using an extension cord, the GFCI on the Hole Cutting Tool does not protect the extension cord. If the outlet is not GFCI protected, it is advisable to use a plug-in type GFCI between the outlet and the extension cord to reduce the risk of shock if there is a fault in the extension cord.

Operating Instructions

Always wear appropriate eye protection. Cutting tools can break or shatter. Cutting produces chips that can be thrown or fall into the eyes.
Do not use for hot tapping. When cutting into an existing system, the pipe must be drained and depressurized prior to cutting. This reduces the risk of electrical shock and another serious injury.
Do not wear gloves or loose clothing when operating the machine. Keep Sleeves and jackets buttoned. Do not reach across the machine. Clothing can be caught by the machine resulting in entanglement. Keep fingers and hands away from rotating chuck and saw. This reduces the risk of entanglement and cutting injuries. Follow operating instructions to reduce the risk of injury from electrical shock entanglement, crushing, and other causes and prevent Hole Cutter damage.

1.  Confirm that the Hole Cutting Tool and work area are properly set up and that the work area is free of bystanders and other distractions.
2.  Assume a proper operating position that will allow:
3. Control of the Hole Cutting Tool, including the ON/ -OFF switch and the feed handle. On the HC-300 you must be on the same side as the switch and the feed handle. Do not turn the tool ON yet
4. Good balance. Be sure that you do not have to overreach.
5. Move the ON/OFF switch to the ON position. Observe the rotation of the hole saw and pilot drill, making sure it is running straight and true. If they wobble, or any other issues are noted, move the switch to OFF and unplug the tool, fix any issues prior to using. Keep fingers, hands, and clothes away from the turning chuck to help reduce the risk of entanglement.
6.  Place both hands on the handwheel and advance the pilot drill into contact with the pipe. Apply firm pressure, and start drilling the pilot hole. Do not force the pilot drill/hole saw. This can overload the hole saw and the tool motor and cause premature failure. Once the hole saw is in contact with the pipe, continue to apply firm pressure. Depending on the size and wall thickness of the pipe and the size of the hole is cut, the hole saw may need to be retracted slightly at times for chip removal. If needed, the Hole Cutting Tool can be shut off and a small amount of appropriate cutting lubricant applied to the workpiece. Do not apply lubricant while the tool is running, this increases the risk of entanglement. Take appropriate steps to prevent the lubricant from dripping or being thrown during use. As the hole saw moves through the pipe and as the cut is completed, there will be an interrupted cut at times. Decrease pressure as this occurs to help prevent jamming of the hole saw.
7.  Once the hole is complete, retract the hole saw from the pipe and turn the ON/OFF switch OFF.
8.  Reverse the mounting procedure to remove the Hole Cutting Tool from the pipe. Make sure you have a secure grip on the Hole Cutting Tool prior to loosening the chain or pulling the plunger on the HC-300.
9. If the pipe slug needs to be removed from the hole saw, always make sure that the ON/OFF switch is in the OFF position and the Hole Cutting Tool is un-plugged before removing. Remove the slug with care, the slug may be hot and edges can be sharp.

Maintenance Instructions

Make sure that the ON/OFF switch is in the OFF position and the tool is unplugged before performing any maintenance or making any adjustments. Maintain tools according to these procedures to reduce the risk of injury from electrical shock, entanglement, and other causes.
Cleaning
After each use, wipe any chips or oil off with a soft, clean, damp cloth, especially areas of relative motion such as the posts. Clean any dust and debris from the motor vents.
Lubrication
The Hole Cutting Tools gearboxes are designed as sealed systems, and should not require any additional grease unless significant leakage has occurred. In those cases, the tools should be returned to a service center. Do not lubricate the bearings that ride on the posts. The bearings are not designed to be used with lubricants, and lubricants will hold dirt and debris that could damage the bearings. As needed, the chain and screw assemblies can be lubricated with light lubricating oil. Wipe any excess oil from exposed surfaces.
Changing Brushes
Check motor brushes every six months and replace them when worn to less than 1/2″.

1.  Remove four screws holding motor cover, remove the cover.
2.  Using a pair of pliers, pull the motor brushes straight out. Detach the connector. (See Figure 12)
3.  Inspect the commutator for wear. If excessively worn, have the tool serviced.
4.  Depress the brush into the holder and insert it into the motor housing. Inspect to make sure insulator sheets are properly positioned between brush holder and housing. Attach the connector and replace the motor cover.

Gib Screw Adjustment
Gib screws are provided on the HC-450 to allow adjustment of the drag between the base and motor assemblies. Tighten or loosen the Gib screws to adjust as desired. (See Figure 13)
