GENERAL SAFETY RULES — FOR ALL POWER TOOLS

WARNING

READ ALL INSTRUCTIONS

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

SAVE THESE INSTRUCTIONS

WORK AREA SAFETY

1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.

2. Do not operate power tools in ex-

plosive atmospheres, such as in the presence of ﬂ ammable liquids, gases, or dust. Power tools create sparks which

may ignite the dust or fumes.

3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

4. 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.

5. 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.

6. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

7. 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.

8. When operating a power tool out-

doors, use an extension cord suitable for outdoor use. Use of a cord suitable

for outdoor use reduces the risk of electric shock.

PERSONAL SAFETY

9. Stay alert, watch what you are do-

ing 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.

10. Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

11. Avoid accidental starting. Ensure the

switch is in the off-position before plugging in. Carrying tools with your ﬁ nger on

the switch or plugging in power tools that have the switch on invites accidents.

12. 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.

13. Do not overreach. Keep proper foot- ing and balance at all times. This enables better control of the power tool in unexpected situations.

14. Dress properly. Do not wear loose

clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery, or long

hair can be caught in moving parts.

15. If devices are provided for the connec-

tion of dust extraction and collection facilities, ensure these are connected and properly used. Use of these de-

vices can reduce dust-related hazards.

POWER TOOL USE AND CARE

16. 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.

17. 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.

18. 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 preven-

tive safety measures reduce the risk of starting the tool accidentally.

19. Store idle power tools out of the reach

of children and do not allow persons unfamiliar with the power tools or these instructions to operate power tools. Power tools are dangerous in the

hands of untrained users.

20. 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.

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

22. Use the power tool, accessories and

tool bits etc., in accordance with these instructions and in the manner intended for the particular type of power tool, 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

23. 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

1. Hold power tools by insulated grip-

ping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord.

Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.

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

3. 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 speciﬁ cally designed to ﬁ lter out microscopic particles.

WARNING

Improperly connecting the grounding wire can result in the risk of electric

shock. Check with a qualiﬁ ed electri- cian 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.

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 Figure A). 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.

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.

Your 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 Figure A.

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

EXTENSION CORDS

TOOL ASSEMBLY

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.

Adjusting Locator Assembly (Fig. 8)

The locator assembly controls the tool's driving depth. These screwdrivers feature a locator assembly with one-handed depth adjustment. Depth adjustments can be made easily and quickly by turning the locator with one hand. Detents inside the sleeve “lock” the selected depth.

For the drywall ramp-off locator assembly, start with about 1/16" clearance between the head of the screw and nose with the snapaction clutch disengaged as shown.

For both locator assemblies, the detents on the inside of the sleeve represent different depths. Every two clicks of the locator equal 1/64". Continue adjusting the locator to the desired depth.

2. To decrease the driving depth, simply rotate the locator in the direction labeled .

The detents “lock” the locator in place,

ensuring an accurate depth setting.

3. To remove the locator assembly, turn the ramp-off sleeve while pulling it away from the tool. Reattaching the locator assembly will not change the depth setting.

Adjusting Torque Setting

These screwdrivers have a torque setting adjustment collar for driving different types of screws into different materials. When properly adjusted, the clutch will slip at a preset torque to prevent driving the screw too deep and to prevent damage to the screw or tool.

For Cat. Nos. 6580-20 & 6581-20 (Fig. 9)

The 6580-20 Screwdriver has a torque setting adjustment collar that may be adjusted to one of forty-four settings. The torque is adjustable from 10 to 140 inch-pounds.

The 6581-20 Screwdriver has a torque setting adjustment collar that may be adjusted to one of thirty-three settings. Beyond setting thirty-three, the tool will stall before slipping the clutch. The torque is adjustable from 10 to 110 inch-pounds.

To select a setting, turn the adjustment collar in the direction indicated on the tool. The selected setting will appear in the window as shown (Fig. 9).

Fig. 9

For Cat. No. 6780-20 (Fig. 10)

The 6780-20 Screwdriver has a torque setting adjustment collar that may be adjusted to one of twenty-one settings. The torque is adjustable from 10 to 140 inch-pounds.

To select a setting, turn the adjustment collar on the tool. The selected setting will appear above the arrow as shown (Fig. 10).

NOTE: Use a piece of scrap material to

test the different settings before driving screws into workpiece. To determine a speciﬁ c setting for your application, use a torque wrench to check the correct torque at any particular setting.

APPLICATIONS

WARNING

To reduce the risk of explosion, electric shock and property dammage. always check the work area for hidden pipes and wires before drilling.

Driving Drywall Screws (Fig. 11) For Screwdrivers Rated 0-4000 RPM

Standard drywall screws are generally designed for attaching drywall to wood studs and 26 through 20-gauge steel studs. MILWAUKEE Screwdrivers are ideal for driving these types of drywall screws. The depth setting is very important. Refer to the guide below for the correct depth setting (Fig. 11).

Fig. 11

Correct. Head of screw

is below surface, but does not puncture facing.

Too deep. Head of screw punches hole in drywall surface, making finishing difficult and allowing moisture beneath facing. Decrease depth.

1. Select the proper drywall screw for each job. Pilot holes are not needed. T o insert screws, place the screw onto the insert bit, then align the screw against the work surface, making sure to hold the tool and screw square to the work surface.

If the tool or screw are misaligned,

the screw will not drive into the work surface or it will not drive straight.

2. Pull the trigger and push the tool forward with a “punching” motion to sink the screw into the drywall. A punching motion will engage the snap-action clutch, cause the screw to start rotating, sink the screw and disengage the snap-action clutch within a fraction of a second. If pressure is not maintained on the tool after engaging the snap-action clutch, the screw will not properly seat.

The snap-action clutch will automatically

disengage and the insert bit will stop rotating once the screw has been driven to the selected depth.

These screwdrivers feature a snap-ac-

tion clutch, which may ratchet slightly when the screw is sunk to the selected depth.

NOTE: Practice driving screws into

pieces of scrap material to become familiar with the tool and the snapaction clutch action before attempting to drive screws into the workpiece.

3. To remove screws, remove the locator assembly and switch the forward/ reverse switch to the reverse position. Reattaching the locator assembly will not change the depth setting.

HIGHER -TORQUE - LOWER

SETTING

NOTE: Use a piece of scrap material to test the different settings before driving screws into workpiece. To determine a speciﬁ c setting for your application, use a torque wrench to check the correct torque at any particular setting.

Too shallow. Head of screw extends above drywall face and can not be finished off. Increase depth.

10 11

Driving Decking Screws (Fig. 12) For Screwdrivers with Depth Locators Rated 0-2500 RPM

Standard decking screws are generally designed for attaching wood to wood studs. MILWAUKEE Screwdrivers are ideal for driving these types of decking screws. The depth setting is very important. Refer to the guide below for the correct depth setting (Fig. 12).

Fig. 12

Correct. Head of

screw is below surface.

Too deep. Head of screw punches hole in surface, allowing moisture to collect. Decrease depth.

Too shallow. Head of screw extends above surface. Increase depth.

1. Select the proper decking screw for each job. Pilot holes are not needed. T o insert screws, place the screw onto the insert bit, then align the screw against the work surface, making sure to hold the tool and screw square to the work surface.

If the tool or screw are misaligned,

the screw will not drive into the work surface or it will not drive straight. Wood screws have sharp points or drill points, and course threads that help the screw through the wood.

2. Pull the trigger and push the tool forward to sink the screw into the wood. A quick motion will engage the snap-action clutch, cause the screw to start rotating, sink the screw and disengage the snap-action clutch within a fraction of a second. If pressure is not maintained on the tool after engaging the snap-action clutch, the screw will not properly seat.

The snap-action clutch will automatically

disengage and the insert bit will stop rotating once the screw has been driven to the selected depth.

These screwdrivers feature a snap-ac-

tion clutch, which may ratchet slightly when the screw is sunk to the selected depth.

NOTE: Practice driving screws into

pieces of scrap material to become familiar with the tool and the snapaction clutch action before attempting to drive screws into the workpiece.

3. To remove screws, remove the locator assembly and switch the forward/ reverse switch to the reverse position. Reattaching the locator assembly will not change the depth setting.

Driving Self-Drilling Screws into Cold-Formed Steel Framing (Fig. 13) For Adjustable Torque Screwdrivers Rated 0-2500 RPM

Follow this procedure when working with light gauge sheet metal, 20 gauge and thicker.

The screw may hesitate slightly when it ﬁ nishes breaking through the ﬁ rst layer of material and starts to penetrate the sheet metal. This is normal. Keep ﬁ rm pressure on the tool until the screw is fully seated.

Self-drilling and self-tapping screws drill, tap and fasten in one quick, easy motion without a separate drilling operation. Their unique design works in metal up to 1/2" thick, giving a strong, reliable hold. The drill point ensures rapid drilling and consistently low drilling pressure while the drill ﬂ utes remove drilling chips. The pilot section ensures that drilling is completed before the ﬁ rst thread engages the material. These screws can be used in many applications as shown at the right.
