GENERAL POWER TOOL SAFETY WARNINGS
WARNING!
Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire 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.
WORK AREA SAFETY
• Keep the 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 flammable 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. Unmodified
plugs and matching outlets will reduce the 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 the cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

model no. 054-8146-8 | contact us 1.800.689.9928
• 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 ground-fault circuit interrupter (GFCI) protected supply. Use of a GFCI 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 the tool while tired or under the influence 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 finger 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, jewellery or long
hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection facilities, ensure that these are connected and properly used. Use of these
devices 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 more safely 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, 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 qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool
is maintained.
ADDITIONAL SAFETY RULES FOR RECIPROCATING SAWS
• Hold the power tool by the insulated gripping surfaces when performing an operation where the cutting accessory may contact hidden wiring or its own cord. If a cutting accessory contacts a “live” wire, it may make the exposed
metal parts of the power tool “live” and could give the operator an electric shock.
• Use clamps or another practical way to support the workpiece and secure it to a stable platform. Holding the work by hand or against your body leaves it
unstable and may lead to loss of control.
• Before starting to cut, turn the tool “ON” and allow the blade to come to full speed. The tool can chatter or vibrate if the blade speed is too slow at the
beginning of cut and could kickback.
• Always disconnect the tool from the power source before changing the saw blade and/or adjusting the saw base.
• The saw blade must be securely locked in its holder. Check that the blade has been securely seated before use.
• Make certain that all adjusting screws and the blade holder are tight before making a cut. Loose adjusting screws and holders can cause the tool or blade
to slip and loss of control may result.
• Check that the switch is “off” before plugging the tool in. Accidental starting could cause injury.
• Secure material before cutting. Never hold it in your hand or across legs. Small or thin material may flex or vibrate with the blade, causing loss of control.
• Never touch the saw blade immediately after use. It may be hot after prolonged use.

IMPORTANT INFORMATION
Before attempting to use this reciprocating saw, become familiar with all of its operating features and safety requirements.
This reciprocating saw features the ideal speed/stroke combination for efficient cutting. For optimum performance and safety, read the following operating instructions before using.
VARIABLE SPEED (g1)
The trigger switch delivers higher speed with increased trigger pressure, and lower speed with decreased trigger pressure.
LIVE TOOL INDICATOR (g2)
Your reciprocating saw has a “live tool indicator” green light, located where the power cord enters the handle. This green light is always on when the saw is plugged into a power source.
ASSEMBLY INSTRUCTIONS
INSTALLING A SAW BLADE (g3)
1. Disconnect the saw from the power supply.
2. Open the blade-clamp lever.
3. Insert the saw blade into the blade clamp as far as possible, and close the blade clamp lever to lock the blade in position.
REMOVING THE SAW BLADE (g3)
1. Disconnect the saw from the power supply.
2. Open the blade-clamp lever.
3. Remove the saw blade from the blade clamp.
BASE (SHOE) ASSEMBLY
SLIDING THE SHOE IN OR OUT(g4)
For maximum control and longer blade life, the base assembly slides in or out to adjust the effective stroke length.
1. Disconnect the saw from the power supply.
2. Press the shoe-release button and slide the shoe to the desired position. The shoe can be locked in any position.
3. Release the shoe-release button to lock the shoe in the desired position.
ASSEMBLY INSTRUCTIONS
WARNING!
• Make sure that the front end of the blade extends through the footplate for the entire stroke length. Do not use specialty blades that are very short or those with a significant cant. The blade must not contact the footplate at any point in its stroke. A blade that is too short or canted could jam inside the foot and snap.
IMPORTANT INFORMATION
WARNING!
• Do not allow familiarity with the reciprocating saw to cause a lack of alertness. A fraction of second of carelessness is enough to cause severe injury.
• If any part of the reciprocating saw is missing or damaged, do not use the saw until the part has been repaired or replaced. Failure to head this warning could result in serious injury.
• Always unplug the tool from the power source before making any adjustment or attaching accessories.

PIVOTING THE SHOE (g5)
The shoe pivots to provide maximum control against the surface being cut.
1. Disconnect the saw from the power supply.
2. Hold the saw securely, and then pivot the shoe to the desired angle.
SCROLLING/ORBITAL/STRAIGHT FUNCTION (g6)
1. Disconnect the saw from the power supply.
2. Turn the indicator to the “
position to allow the saw head to be rotated relative to the body.
3. Move the indicator to either cutting action setting to lock the saw head in position.
4. Turn the indicator to the “
position for straight cutting action.
5. Turn the indicator to the “
” position for orbital cutting action.
This reciprocating saw has a pendulum action to make the blade swing slightly as it cuts.
Pendulum action increases the speed of the cut, but may result in a rougher finish to the cut in some materials.
Experiment on a piece of scrap material to determine the optimum pendulum action setting.
OPERATING INSTRUCTIONS
TURNING THE SAW ON AND OFF
1. Depress the trigger switch to turn the saw ON.
2. Release the trigger switch to turn the saw OFF.
GENERAL CUTTING
1. Make sure that the workpiece is firmly clamped.
2. Use the appropriate type and size of blade for the workpiece material and size.
3. Adjust the pivot shoe as necessary to expose unworn blade teeth for longer blade life.
4. Check for clearance behind the workpiece so that the blade will not impact another surface.
5. Clearly mark the line of cut on the workpiece. If cutting metal, apply cutting oil on the line.
6. Connect the power cord of your reciprocating saw to a standard household power outlet.
7. Hold the saw firmly with both hands. Make sure to keep your hands on the insulated gripping areas only.
ASSEMBLY INSTRUCTIONS
OPERATING INSTRUCTIONS
WARNING!
• Before plugging in the tool, always check to determine that the switch performs properly and returns to the “OFF” position when released.
• Hold the tool only by the plastic handle and the insulated grip area to help prevent electrical shock. When sawing into walls or floors you may encounter electrical wiring. Sawing into a “live” wire will cause electric shock.
• Do not allow familiarity with the saw to make you careless. One careless fraction of a second is enough to inflict serious injury
NOTICE:
• If sawing fiberglass, plaster, wallboard, or spackling compound, clean the motor vents frequently with a vacuum or compressed air. These materials are highly abrasive and may accelerate the wear on motor bearings and brushes.
• Always wear safety goggles when cleaning tools using compressed air.
•Cutting speeds should vary with the workpiece. Hard materials, such as
metals, require lower speeds; for softer materials use higher speeds.

8. Depress the trigger switch to start the saw and bring it to the maximum desired cutting speed before applying the blade to the workpiece.
9. Do not force the tool. Place the shoe firmly on the workpiece while cutting. Use only enough steady pressure on the blade to keep the saw cutting.
10. Reduce pressure as the blade comes to the end of the cut.
11. Release the trigger switch. Allow the saw to come to a complete stop before removing the blade from the workpiece.
12. If sawing fiberglass, plaster, wallboard, or spackling compound, clean the motor vents frequently with a vacuum or compressed air. Always wear safety goggles when cleaning tools using compressed air. These materials are highly abrasive and may accelerate the wear on motor bearings and brushes.
PLUNGE CUTTING
Your reciprocating saw is ideal for plunge cutting directly into surfaces that cannot be cut from an edge, such as walls or floors.
Plunge cutting may be done two ways, depending on how the blade is inserted.
In thick materials and in harder materials, such as metal, plunge cutting should not be attempted. Such materials can be cut with the reciprocating saw only by starting the cut from the edge of the material or from a hole drilled all the way through the material that is large enough to accommodate the saw blade.
1. Insert the blade into the tool. If the blade was inserted with the teeth facing down toward the lower surface of the tool, hold the tool as shown in fig 7, resting the edge of the shoe on the workpiece. If the blade was inserted with the teeth facing up toward the upper surface of the tool, hold the tool as shown in fig 8, resting the edge of the shoe on the workpiece as shown.
2. Raise the blade so that it is just above the workpiece and does not contact the workpiece.
3. With the blade just above the workpiece, depress the trigger switch. Then using the edge of the shoe as a pivot, lower the blade into the workpiece (fig 9).
4. As the blade starts cutting, raise the handle of the tool slowly until the shoe rest firmly on the workpiece. Then guide the tool along your cutting line to acquire the desired cut.
5. After the blade has penetrated through the workpiece, continue sawing along the marked cutting line (fig 10).
6. Release the trigger switch. Allow the saw to come to a complete stop before removing the blade from the workpiece.
METAL CUTTING
The saw can be used to cut metals, such as sheet steel, pipe, steel rods, aluminium, brass, and copper. Be careful not to twist or bend the saw blade. Do not force the tool.
The use of cutting oil is recommended when cutting soft metals and steel. Cutting oil will keep the blade cool, increase cutting action, and prolong blade life.
1. Securely clamp the workpiece in position, and make the cut close to the clamping point to minimize vibration of the work being cut.
2. When cutting conduit pipe or angle iron, clamp the work in a vise, if possible, and cut close to the vise.
3. To cut thin sheet material, “sandwich” the material between pieces of hardboard or plywood, and clamp the layers together in order to reduce vibration and tearing of the material.
