WARNING:  
For your personal safety, READ and UNDERSTAND before using.  
SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.  
5. Avoid body contact with grounded sur-  
faces such as pipes, radiators, ranges and  
refrigerators. There is an increased risk of  
electric shock if your body is grounded.  
14. Use safety equipment. Always wear eye  
protection. Dust mask, non-skid safety  
shoes, hard hat, or hearing protection must  
be used for appropriate conditions. Ordinary  
eye or sun glasses are NOT eye protection.  
6. Do not expose power tools to rain or wet  
conditions. Water entering a power tool will  
increase the risk of electric shock.  
Tool Use and Care  
15. Use clamps or other 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.  
7. Do not abuse the cord. Never use the cord  
to carry the tools 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.  
16. Do not force tool. Use the correct tool for  
your application. The correct tool will do the  
job better and safer at the rate for which it is  
designed.  
8. 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.  
17. Do not use tool if switch does not turn it  
on or off. Any tool that cannot be controlled  
with the switch is dangerous and must be  
repaired.  
Personal Safety  
9. Stay alert, watch what you are doing and  
use common sense when operating a  
power tool. Do not use 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.  
18. Disconnect the plug from the power  
source before making any adjustments,  
changing accessories, or storing the tool.  
Such preventive safety measures reduce the  
risk of starting the tool accidentally.  
19. Store idle tools out of reach of children  
and other untrained persons. Tools are  
dangerous in the hands of untrained users.  
10. Dress properly. Do not wear loose cloth-  
ing 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.  
20. 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.  
11. Avoid accidental starting. Be sure switch  
is off before plugging in. Carrying tools with  
your finger on the switch or plugging in tools  
that have the switch on invites accidents.  
21. Check for misalignment or binding of  
moving parts, breakage of parts, and any  
other condition that may affect the tools  
operation. If damaged, have the tool ser-  
viced before using. Many accidents are  
caused by poorly maintained tools.  
12. Remove adjusting keys or wrenches  
before turning the tool on. A wrench or a  
key that is left attached to a rotating part of  
the tool may result in personal injury.  
22. Use only accessories that are recom-  
mended by the manufacturer for your  
model. Accessories that may be suitable for  
one tool, may become hazardous when used  
on another tool.  
13. Do not overreach. Keep proper footing  
and balance at all times. Proper footing and  
balance enables better control of the tool in  
unexpected situations.  
3
24. When servicing a tool, use only identical  
replacement 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  
electric shock or injury.  
SERVICE  
23. Tool service must be performed only by  
qualified repair personnel. Service or main-  
tenance performed by unqualified personnel  
could result in a risk of injury.  
USE PROPER EXTENSION CORD: Make sure your extension cord is in good condition.  
When using an extension cord, be sure to use one heavy enough to carry the current your  
product will draw. An undersized cord will cause a drop in line voltage resulting in loss of  
power and overheating. Table 1 shows the correct size to use depending on cord length and  
nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage num-  
ber, the heavier the cord.

SPECIFIC SAFETY RULES  
USB012-2  
DO NOT let comfort or familiarity with product (gained from  
repeated use) replace strict adherence to recipro saw safety  
rules. If you use this tool unsafely or incorrectly, you can suffer  
serious personal injury.  
1. Hold tool by insulated gripping surfaces  
when performing an operation where the  
cutting tool may contact hidden wiring or  
its own cord. Contact with a livewire will  
make exposed metal parts of the tool live”  
and shock the operator.  
4. Do not cut oversize workpiece.  
5. Check for the proper clearance beyond  
the workpiece before cutting so that the  
blade will not strike the floor, workbench,  
etc.  
6. Hold the tool firmly.  
2. Always use safety glasses or goggles.  
Ordinary eye or sun glasses are NOT  
safety glasses.  
7. Make sure the blade is not contacting the  
workpiece before the switch is turned on.  
3. Avoid cutting nails. Inspect workpiece for  
any nails and remove them before opera-  
tion.  
8. Keep hands away from moving parts.  
4
9. Do not leave the tool running. Operate the  
tool only when hand-held.  
11. Do not touch the blade or the workpiece  
immediately after operation; they may be  
extremely hot and could burn your skin.  
10. Always switch off and wait for the blade to  
come to a complete stop before removing  
the blade from the workpiece.  
12. Some material contains chemicals which  
may be toxic. Take caution to prevent  
working dust inhalation and skin contact.  
Follow material supplier safety data.

Adjusting the shoe  
1
When the blade loses its cutting efficiency in one place along  
its cutting edge, reposition the shoe to utilize a sharp, unused  
portion of its cutting edge. This will help to lengthen the life of  
the blade.  
To reposition the shoe, loosen the lever counterclockwise  
and slide the shoe forward or back to the desired position.  
Then tighten the lever to firmly secure the shoe.

ward on the cutting stroke and greatly increases cutting  
speed.  
To change the cutting action, press the stopper and turn the  
lever to the desired cutting action position. Then, release the  
stopper to lock the lever. Refer to the table to select the  
appropriate cutting action.

Installing or removing saw blade  
CAUTION:  
1
Always clean out all chips or foreign matter adhering to  
the blade, blade clamp and/or slider. Failure to do so  
may cause insufficient tightening of the blade, resulting  
in a serious injury.  
To install the blade, loosen the screw on the blade clamp with  
the hex wrench. Insert the blade between the leaf spring and  
the slider so that the pin on the slider fits into the hole in the  
blade shank. If the pin cannot easily fit into the hole, remove  
the hex wrench from the screw and then try again.  
1. Hex wrench  
After the pin fits properly into the hole, tighten the screw  
clockwise securely while making sure that the blade cannot  
be extracted even though you try to pull it out.  
002507  
1
CAUTION:  
2
If you tighten the screw without the pin on the slider  
fitting properly in the hole in the blade shank, the pin or  
the blade shank will be damaged. This may cause the  
blade to be extracted unexpectedly during operation.

OPERATION  
CAUTION:  
Always press the shoe firmly against the workpiece  
during operation. If the shoe is held away from the  
workpiece during operation, strong vibration and/or  
twisting will be produced, causing the blade to snap  
dangerously.  
Always wear gloves to protect your hands from hot flying  
chips when cutting metal.  
Be sure to always wear suitable eye protection which  
conforms with current national standards.  
Always use a suitable coolant (cutting oil) when cutting  
metal. Failure to do so will cause premature blade wear.

002517  
Press the shoe firmly against the workpiece. Do not allow the  
tool to bounce. Bring the blade into light contact with the  
workpiece. First, make a pilot groove using a slower speed.  
Then use a faster speed to continue cutting.  
MAINTENANCE  
CAUTION:  
Always be sure that the tool is switched off and  
unplugged before attempting to perform inspection or  
maintenance.

when they wear down to the limit mark. Keep the carbon  
brushes clean and free to slip in the holders. Both carbon  
brushes should be replaced at the same time. Use only iden-  
tical carbon brushes.
