ADDITIONAL SAFETY RULES FOR TOOL ENB012-1
1. Hold tool by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring or its own cord. Con-
tact with a “live”wire will make exposed metal parts
of the tool “live”and shock the operator.
2. Avoid cutting nails. Inspect workpiece for any
nails and remove them before operation.
3. Do not cut oversize workpiece.
4. Check for the proper clearance beyond the
workpiece before cutting so that the blade will
not strike the floor, workbench, etc.
5. Hold the tool firmly.
6. Make sure the blade is not contacting the work-
piece before the switch is turned on.
7. Keep hands away from moving parts.
8. Do not leave the tool running. Operate the tool
only when hand-held.
9. Always switch off and wait for the blade to come
to a complete stop before removing the blade
from the workpiece.
10. Do not touch the blade or the workpiece immedi-
ately after operation; they may be extremely hot
and could burn your skin.

FUNCTIONAL
DESCRIPTION CAUTION:
•Always be sure that the tool is switched off and unplugged before
adjusting or checking function on the tool.
Adjusting the shoe
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.
Selecting the cutting action
This tool can be operated with an orbital or a straight line cutting action. The
orbital cutting action thrusts the blade forward 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.
Switch action
CAUTION:
•Before plugging in the tool, always check to see that the switch trigger
actuates properly and returns to the “OFF”position when released.
For tools with the lock button
To start the tool, simply pull the switch trigger. Tool speed is increased by
increasing pressure on the switch trigger. Release the switch trigger to stop.

Tool speed can be adjusted by turning the speed change knob. When the por-
tion with mark is positioned adjacent to the pointer, faster speed can be
obtained by turning the knob clockwise. When the portion with mark is
positioned adjacent to the pointer, full speed can be obtained.
Continuous operation can be performed only when the knob is set to the full
speed position. To perform continuous operation, pull the switch trigger fully
and then push the lock button up. To stop the tool from the locked position, pull
the switch trigger fully, then release it.
For tools with the lock-off button
To prevent the switch trigger from being accidentally pulled, a lock-off button is
provided. To start the tool, push the lock-off button up and pull the switch trig-
ger.
Tool speed is increased by increasing pressure on the switch trigger. Release
the switch trigger to stop.
Tool speed can be adjusted by turning the speed change knob. When the por-
tion with mark is positioned adjacent to the pointer, faster speed can be
obtained by turning the knob clockwise. When the portion with mark is

ASSEMBLY CAUTION:
•Always be sure that the tool is switched off and unplugged before
carrying out any work on the tool.
Installing or removing saw blade
CAUTION:
•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.
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.

CAUTION:
•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.
To remove the blade, follow the installation procedure in reverse.
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.
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.
