SAFETY INSTRUCTIONS
WARNING:
Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, 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.
WARNING:
Risk of re and electric shock. Dry location use only. Do not expose to rain. Risk of injury.
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
2. 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.
3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. 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 risk of electric shock.
2. 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.
3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
4. 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.
5. 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.
6. 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
1. 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.
2. Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat, or hearing protection, used for appropriate conditions, will reduce personal injuries.
3. Prevent unintentional starting. Ensure that 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 energizing power tools that have the switch on invites accidents.

Power tools are dangerous in the hands of untrained users.
5. 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.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
7. 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.
BATTERY TOOL USE
AND CARE
1. Recharge only with the charger specified by the manufacturer. A charger
that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
2. Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
3. When the battery pack is not in use,
keep it away from other metal objects, such as paper clips, coins, keys, nails, screws or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals
together may cause burns or a fire.
4. Under abusive conditions, liquid may
be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, also seek
medical help. Liquid ejected from the battery
may cause irritation or burns.

OPERATION
WARNING:
Before attach the battery pack on the tool, always check to determine that the switch performs properly and returns to the “OFF” position when released.
WARNING:
Hold the tool only by the plastic handle and the insulated grip area to help prevent electrical shock. When sawing into walls or oors you may encounter electrical wiring. Sawing into a “live” wire will cause electric shock.
1. Remove the battery pack from the saw.
2. Make sure that the workpiece is
firmly clamped.
3. Use the appropriate type and size
of blade for the workpiece material and size.
4. Adjust the pivot shoe as necessary to
make sure that the blade will extend beyond the shoe and the workpiece at all times.
5. Adjust the pivot shoe as necessary to
expose unworn blade teeth for longer blade life.
6. Check for clearance behind the
workpiece so that the blade will not impact another surface.
7. Mark the line of cut clearly. If cutting
metal, apply cutting oil on the line.
8. Attach the battery pack on the saw.
9. Hold the saw firmly with both hands.
Make sure to keep your hands on the insulated gripping areas only.
10. Depress the lock-off button and trigger
switch to start the saw and bring it to the maximum desired cutting speed before applying the blade to the workpiece.
11. 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.
12. Reduce pressure as the blade comes to
the end of the cut.
13. Allow the saw to come to a complete
stop before removing the blade from the workpiece.
14. If sawing fiberglass, plaster, wallboard, or spackling compound, clean the saw motor vents frequently with a vacuum or compressed air. These materials are highly abrasive and may accelerate the wear on motor bearings and brushes.
NOTICE: Cutting speeds should vary with the workpiece. Hard materials, such as metals, require lower speeds; for softer materials use higher speeds.
WARNING:
Do not allow familiarity with the saw to make you careless. One careless fraction of a second is enough to inict serious injury.
PLUNGE CUTTING (FIG. 7)
FIG. 7
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. Column A shows how to plunge cut with the teeth of the blade facing down. Column B shows how to plunge cut with the teeth of the blade facing up.
A B
Page 13
Page 12
OPERATION
WARNING:
Do not plunge cut into
metal surfaces.
1. Insert the blade into the tool. If the blade inserted with the teeth facing downward, hold the tool as shown in Column A, resting the edge of the shoe on the workpiece.
2. If you inserted the blade with the teeth facing upward, hold the tool as shown in Column B, resting the edge of the shoe on the workpiece as shown.
3. With the blade just above the workpiece, depress the trigger switch, using the edge of the shoe as a pivot, lower the blade into the workpiece
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.
NOTICE: To make plunge cutting easier, use a heavy gauge blade and install the blade with the teeth facing upward as show in column B.
WARNING:
To reduce the risk of explosion, electric shock and property damage, always check the work area for hidden gas pipes, electrical wires or water pipes when making blind or plunge cut.
WARNING:
To avoid loss of control and serious injury, make sure that the blade reaches maximum speed before touching it to the workpiece.
WARNING:
Do not make plunge cuts in metal materials.
METAL CUTTING
The saw can be used to cut metals, such as sheet steel, pipe, steel rods, aluminum, brass, and copper. Be careful not to twist or bend the saw blade. Do not force. 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.
WARNING:
Never use gasoline, because normal sparking could ignite the fumes.
1. Securely clamp the workpiece in
position, and make the cut close to the clamping point in order 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.

MAINTENANCE
WARNING:
Always wear safety goggles or safety glasses with side shields during power tool operations, or when blowing dust. If operation is dusty, also wear a dust mask.
It has been found that electric tools are subject to accelerated wear and possible premature failure when they are used to work on ber glass boats and sports cars, wallboard, spackling compounds or plaster. The chips and grindings from these materials are highly abrasive to electrical tool parts, such as bearings, brushes, commutators, etc. Consequently, it is not recommended that this tool be used for extended work on any berglass mate­rial, wallboard, spackling compound or plas­ter. During any use on these materials, it is extremely important that the tool is cleaned frequently by blowing with an air jet
WARNING:
Do not at any time let brake uids, gasoline, petroleum-based products, penetrating oils, etc. come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic, which may result in serious personal injury.
Periodic maintenance allows for long life and trouble-free operation. A cleaning, lubrication and maintenance schedule should be maintained. As a common preventive maintenance practice, follow these recommended steps:
1. When work has been completed, clean
the tool to allow smooth functioning of the tool over time.
2. Use clean damp cloths to wipe the tool.
3. Check the state of all electrical cables.
4. Keep the motor air openings free from oil, grease and sawdust or woodchips, and store tool in a dry place.
5. Be certain that all moving parts are well lubricated, particularly after lengthy exposure to damp and/or dirty conditions.
LUBRICATION
All of the bearings in this tool are lubricated with a sufcient amount of high-grade lubricant for the life of the tool under normal operating conditions. Therefore, no further lubrication is required.
WARNING:
For your safety, always turn off switch and remove battery pack before performing any maintenance or cleaning.
GENERAL MAINTENANCE
The tool may be cleaned most effectively with compressed dry air. Always wear safety goggles when cleaning tools with compressed air. Avoid using solvents when cleaning plastic parts.
