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

dark areas invite accidents.

• Do not operate power tools in explosive atmospheres, such as in the presence of ﬂ am- mable 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

WORK AREA 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

preventive 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

• Wear ear protectors. Exposure to noise can cause hearing loss.

• Use auxiliary handle(s), if supplied with the

tool. Loss of control can cause personal injury.

• Hold power tools by insulated gripping surfaces, when performing an operation where the cutting tool 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.

• Keep hands away from all cutting edges and moving parts.

• 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 Cana- da) 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.

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.

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. 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 Figure A.

Double Insulated Tools: T ools with Two Prong Plugs

Tools marked “Double Insulated” do

not require grounding. They have a

special double insulation system which satisﬁ es

OSHA requirements and complies with the applica-

ble 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.

OPERATION

Electronic Feedback Control Circuit

These hammers have an Electronic Feedback Control Circuit (EFCC) which helps improve the operation and life of the tool.

Feedback Control

The electronic speed control circuit allows the tool to maintain constant speed and torque between no-load and load conditions.

Soft Start

The Soft-Start feature reduces the amount of torque reaction to the tool and the user. This feature gradually increases the motor speed up from zero to the speed set by the speed control dial.

WARNING T o reduce the risk of injury,

wear safety goggles or glasses with side shields. Unplug the tool before changing accessories or making adjustments.

Selecting Speed

The speed control dial on these hammers allows the user to adjust the rotating speed (RPM) and the impact rate (BPM) of the tool. To change the speed, set the speed control dial to the desired setting.

• Lower speeds provide more control when starting holes and reduce 'spalling' on breakthrough. Spalling occurs when pieces of material chip off around the drilled hole on breakthrough. When chiseling in soft or brittle materials, use lower speeds to reduce damage to surrounding areas of the material.

• Higher speeds provide faster penetration when drilling and chiseling in demolition work.

Selecting Action Cat. No. 5337-20

The cat. no. 5337-20 demolition hammer is for "hammering-only". No rotation is available. Only chisels and other "hammering-only" accessories should be used.

Cat. No. 5339-20

The cat. no. 5339-20 demolition hammer is for "hammering-only". No rotation is available. The action selector is used to select the action:

2. Chisel adjustment. Use this setting to adjust

the angle of the chisel blade in relation to the tool. With a chisel mounted in the tool, twist the chisel to the desired angle. Then, rotate the action selector to the "hammering only" setting for use.

Chisel AdjustmentHammering Only

NOTE: To engage the hammering mechanism,

maintain pressure on the bit/chisel. When pressure is released, hammering stops.

Cat. No. 5340-20

The cat. no. 5340-20 rotary hammer has "hammering-only" and "hammering with rotation", depending on the type of shank inserted into the tool.

For "hammering-only": Insert a chisel or other "hammering-only" accessory with a 3/4" Hex with 21/32" Round "Inserting Bits and Chisels"). The rotational drive mechanism will run but not engage with the chisel, resulting in "hammering-only" action. For "hammering with rotation": Insert a drill or coring bit with a spline shank into the nose of the tool (see "Inserting Bits and Chisels"). The rotational drive mechanism engages with the bit, resulting in "hammering with rotation" action.

Starting and Stopping the Tool

1. To start the tool, pull the trigger.

2. To stop the tool, release the trigger.

Locking the Trigger (Cat. No. 5337-20, 5339-20 only)

The lock button on the demolition hammers holds the trigger in the "On" position for continuous use.

1. To lock the trigger, hold in the lock button while pulling the trigger. Release the trigger.

2. To unlock the trigger, pull the trigger and release. The lock button will pop out.

Cold Hammering

If the hammer is stored for a long period of time or at cold temperatures, the lubrication may become stiff and the tool may not hammer initially or the hammering may be weak. If this happens:

1. Insert a chisel into the tool.

2. Pull the trigger and apply the chisel against a scrap piece of concrete.

3. Turn the tool On and Off every few seconds. After 15 seconds to 2 minutes, the tool will start hammering normally. The colder the hammer is, the longer it will take to warm up.

Operator Force

These hammers feature the Vibration Isolation System to provide the operator with comfort without sacriﬁ cing power or performance. The motor hous- ing is suspended independently from the switch handle. Insulating elements absorb vibration when hammering and drilling. Ideal operator force compresses the handle slightly and allows the tool to work aggressively while the handle provides maximum vibration dampening. Excessive operator force compresses the handle too far and reduces the vibration dampening. Users will be able to feel the difference and should adjust the force to the handle accordingly.

WARNING Applying greater pressure

does not increase the tool's effectiveness. If the applied working pressure is too high, the shock absorber will be pushed together making vibration to the handle noticeably stronger.

Hammering Only

1. Insert a chisel or other "hammering only" accessory into the tool (see "Installing Bits and Chisels").

2. Position the tool on the workpiece.

3. Grasp both handles ﬁ rmly (trigger handle and either the spade handle or straight handle).

4. Pull the trigger. Always hold the tool securely using two handles and maintain control.

5. Use only enough pressure to hold the tool in place, engage the hammering mechanism, and prevent the tip of the chisel from wandering. This tool has been designed to achieve top performance with only moderate pressure. Let the tool do the work.

NOTE: To engage the hammering mechanism,

maintain pressure on the bit/chisel. When pressure is released, hammering stops.

6. When chiseling or chipping, hold the tool at an angle to the work area. For best performance, work from a corner or close the edge of the work and break off a small area at a time.

If a hammer iron gets stuck:

1. Unplug the tool.

2. Pull out bit lock and rotate it 180°.

3. Pull the tool off of the stuck accessory.

4. Remove the accessory from the workpiece.

Hammering with Rotation

1. Insert a drill or coring bit into the tool (see "Installing Bits and Chisels").

2. Position the tool on the workpiece.

3. Grasp both handles ﬁ rmly (trigger handle and straight handle).

WARNING T o reduce the risk of injury,

hold or brace securely. Always be prepared for drill reaction when bit binds, when hole becomes clogged, when striking embedded materials, and during hole breakthrough.

4. Pull the trigger. Always hold the tool securely using the straight handle and trigger handle and maintain control.

5. Use only enough pressure to hold the tool in place, engage the hammering mechanism, and prevent the tip of the bit from wandering. This tool has been designed to achieve top performance with only moderate pressure. Let the tool do the work.

When pressure is released, hammering stops.

6. When drilling deep holes, the speed may begin to drop off. Pull the bit partially out of the hole while the tool is running to help clear dust.

NOTE: Do not use water to settle the dust since

it will clog the bit ﬂ utes and tend to make the bit bind in the hole.

If a bit binds:

If the bit should bind, a built in, nonadjustable slip clutch prevents the bit from turning when the tool is held or braced securely. If this occurs

1. Turn off and unplug the tool.

2. Free the bit from the workpiece.

3. Clear debris from the hole.

4. Begin drilling again.

WARNING Use MILWAUKEE core bits

Cat. No. 48-20-5125 through 48-20-5165. Do not use LHS (Large Hole System) Components with rotary hammers 5340-20 and 5342-20. The bits could fail, breaking apart at the threaded stud and causing injury and property damage.

Using Rotary Percussion Core Bits

Core bits are useful for drilling larger holes for conduit and pipe. MILWAUKEE Heavy-Duty Core Bits have heat-treated steel bodies with durable carbide tips. These core bits are specially designed for fast, accurate drilling with combined hammering and rotary action.

1. Clean and lubricate the threads on the adapter and core bit to make later removal easier. Screw the threaded end of the adapter into the rear of the core bit.

2. Push the guide plate onto the pointed end of the center pin. Insert the center pin and guide plate assembly into the core bit. Be sure the small end of the center pin is securely placed into the hole in the center of the core bit (Fig. 5).

Fig. 5

3. Insert the adapter into the nose of the tool (see “Installing Bits and Chisels”. Set the action selector to the hammering-with-rotation setting.

4. Press the center pin ﬁ rmly against your center mark, hold the tool ﬁ rmly and pull the trigger (Fig. 6). NOTE: If a center pin and guide plate are not available,

Fig. 6

use a template or notched board to start the hole (Fig. 7).

5. After drilling to about the depth of the core bit teeth, remove the center pin and guide plate from the core bit. Resume drilling.

6. T o change the core bit, hold the tool upwards, pointing it away from your

Fig. 7

body, and run the tool allowing rotation and impacting for about ﬁ ve sec- onds to loosen the core bit from the adapter shank.

NOTE: To make

deeper holes, remove the core bit, break and remove the core. Resume drilling. When drilling long or deep holes, after each inch of penetration pull the bit partially out of the hole while the tool is running, to help clear dust from the bit ﬂ utes. Dust can clog the bit ﬂ utes and can make the bit bind in the hole. If this occurs, stop the tool, free the bit and begin again.

Drilling Large Diameter Holes with Core Bits

When drilling holes with large diameter core bits, dust may build up in the cut and can cause the tool to stall, bind, or cut slowly. By creating an opening for the dust to escape, drilling time, bit stress, and tool stress can be reduced.

1. Start the cut as normal.

2. Once the bit is ﬁ rmly established in the cut (about 1/4" deep), remove the bit from the cut (Fig. 8).

3. Remove the bit from the tool.

Fig. 8

4. Install a standard ﬂ ut- ed bit, approximately 7/8" in diameter, onto the tool.

Chiseling and Chipping

These MILWAUKEE Hammers may be used for chipping and chiseling. When chiseling, hold the tool at an angle to the workpiece. Work from a corner or close to the edge of the workpiece, breaking off one small area at a time rather than attempting too large an area. A variety of accessories are available.

Bushing Tools-Used to surface concrete.

Mortar Cutting Chisels (Seam Tools)-For removing old mortar for

tuck pointing or caulking. Bull Points-For demolition work

and starting holes in concrete slabs.

Flat Chisels-For edging, chipping or channeling.

Scaling Chisels-For removing weld spatter or scale and cutting straight lines.

Slotting Chisel-For slotting and cutting between drilled holes in concrete and masonry.

MAINTENANCE

WARNING T o reduce the risk of injury,

always unplug your tool before performing any maintenance. Never disassemble the tool or try to do any rewiring on the tool’s electrical system. Contact a MILW AUKEE service facility for ALL repairs.

Maintaining Tools

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. T ag 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

Maintaining Hammer Chisels

Through normal use, the shank of the chisel can "mushroom" over and cause the chisel to become stuck inside the hammer. To prevent this from happening, periodically remove the chisel from the tool and inspect the shank. If the shank starts to "mushroom", have the chisel refurbished or replaced.

Brush Replacement

These MILWAUKEE hammers are will automatically shut off when the brushes need to be replaced. Return your tool to the nearest MILWAUKEE service facility for repairs.

RÈGLES DE SÉCURITÉ GÉNÉRALES RELATIVES AUX

OUTILS ÉLECTRIQUES

AVERTISSEMENT LIRE TOUTES LES RÈGLES ET INSTRUCTIONS DE SÉCURITÉ.

Ne pas suivre l’ensemble des règles et instructions peut entraîner une électrocution, un

incendie ou des blessures graves. Conserver les règles et les instructions à des ﬁ ns

de référence ultérieure. Le terme «outil électrique» ﬁ gurant dans les avertissements ci-

dessous renvoie à l’outil électrique à alimentation par le réseau (à cordon) ou par batterie (sans ﬁ l).

SÉCURITÉ DU LIEU DE TRA VAIL

•Maintenir la zone de travail propre et bien éclairée. Les zones encombrées ou mal éclairées

sont favorables aux accidents.

•Ne pas utiliser d’outil électrique dans une at-

mosphère explosive, telle qu’en en présence de liquides, de gaz ou de poussières inﬂ ammables.

Les outils électriques génèrent des étincelles qui peuvent enﬂ ammer les poussières ou les fumées.

•T enir les enfants et les personnes non autorisées

à l’écart pendant le fonctionnement d’un outil électrique. Un manque d’attention de l’opérateur

risque de lui faire perdre le contrôle de l’outil.

SÉCURITÉ ÉLECTRIQUE

•La ﬁ che de l’outil électrique doit correspondre à la prise d’alimentation. Ne jamais modiﬁ er la ﬁ che d’une manière quelconque. Ne pas utiliser d’adaptateur avec les outils électriques mis à la terre (à la masse). Des ﬁ ches non modiﬁ ées

et des prises d’alimentation assorties réduisent le risque de choc électrique.

•Éviter tout contact corporel avec des surfaces

reliées à la masse ou à la terre telles que tuyaux, radiateurs, cuisinières et réfrigérateurs.

Un risque de choc électrique plus élevé existe si le corps est relié à la masse ou à la terre.

•Ne pas exposer les outils électriques à la pluie ou à l’humidité. Le risque de choc électrique augmente si de l’eau s’inﬁ ltre dans un outil électrique.

•Prendre soin du cordon. Ne jamais utiliser le

cordon pour transporter, tirer ou débrancher l’outil électrique. Tenir le cordon à l’écart de la chaleur, des huiles, des arêtes coupantes ou des pièces en mouvement. Un cordon endom-

magé ou emmêlé présente un risque accru de choc électrique.

•Se procurer un cordon d’alimentation appro-

prié en cas d’utilisation d’un outil électrique à l’extérieur. L’utilisation d’un cordon d’alimentation

pour usage extérieur réduit le risque de choc électrique.

SÉCURITÉ INDIVIDUELLE

•Être sur ses gardes, être attentif et faire preuve de bon sens en utilisant un outil électrique. Ne pas utiliser un outil électrique en cas de fatigue ou sous l’inﬂ uence de drogues, d’alcool ou de médicaments. Un instant d’inattention lors

de l’utilisation d’un outil électrique peut entraîner des blessures graves.

•Utiliser un équipement de sécurité. Toujours porter des lunettes de protection. Un équipement de sécurité comprenant masque anti-poussière, chaussures de sécurité anti-dérapantes, casque ou dispositif de protection anti-bruit peut, dans les circonstances appropriées, réduire le risque de blessure.

•Éviter tout démarrage accidentel de l’outil.

S’assurer que le commutateur est en position OFF (Arrêt) avant de brancher l’outil. Le port

de l’outil avec un doigt sur le commutateur ou son branchement avec le commutateur en position ON (Marche) sont favorables aux accidents.

•Retirer toute clé de réglage avant de mettre l’outil sous tension. Une clé laissée attachée sur une pièce mobile de l’outil électrique peut entraîner des blessures.

•Ne pas travailler à bout de bras. Bien garder un bon équilibre à tout instant. Ceci permet de mieux préserver la maîtrise de l’outil électrique dans des situations imprévues.

•Porter des vêtements adéquats. Ne pas porter

de vêtements amples ni de bijoux. Ne pas approcher les cheveux, vêtements et gants des pièces en mouvement. Les vêtements amples,

les bijoux ou les cheveux longs risquent d’être happés par les pièces en mouvement.

•Si des dispositifs sont prévus pour l’extraction

et la récupération des poussières, vérifier qu’ils sont connectés et utilisés correctement.

L’utilisation de ces dispositifs peut réduire les risques liés aux poussières.

UTILISATION ET ENTRETIEN

DE L’OUTIL ÉLECTRIQUE

•Ne pas forcer l’outil électrique. Utiliser l’outil

électrique approprié à l’application considérée. L’outil électrique adapté au projet consi-

déré produira de meilleurs résultats, dans des conditions de sécurité meilleures, à la vitesse pour laquelle il a été conçu.

•Ne pas utiliser l’outil électrique si le com- mutateur ne le met pas sous ou hors tension. Tout outil électrique dont le commutateur de marche-arrêt est inopérant est dangereux et doit être réparé.

•Débrancher la ﬁ che de la prise d’alimentation

et/ou la batterie de l’outil électrique avant d’effectuer des réglages, de changer d’accessoires ou de ranger l’outil. De telles

mesures de sécurité préventive réduisent le risque de mettre l’outil en marche accidentellement.

•Ranger les outils électriques inutilisés hors

de la portée des enfants et ne pas laisser des personnes qui connaissent mal les outils électriques ou ces instructions utiliser ces outils. Les outils électriques sont dangereux dans

les mains d’utilisateurs non formés à leur usage.

•Entretien des outils électriques. S’assurer de

l’absence de tout désalignement ou de grippage des pièces mobiles, de toute rupture de pièce ou de toute autre condition qui pourrait affecter le bon fonctionnement de l’outil électrique. En cas de dommages, faire réparer l’outil avant de l’utiliser de nouveau. Les outils
