ately. 
For Proper Use (Further Detail) 
WARNING 
To prevent the risk of serious personal injury: 
z It is important to use an appropriate device 
to hold the material being cut properly, and 
to hold the cutter firmly with both hands to 
prevent loss of control which could cause 
personal injury. 
• Figure 14 shows proper cutting position. 
• Note that hands are kept away from cutting 
area. 
• Make sure bystanders are away from work 
area and from underneath of workpiece. 
• When cutting, do not try to hold the material 
with your hand. 
Cutting large sheets; 
Support large sheets. Be sure to set the 
depth of the cut so that you only cut through 
the workpiece, not through the supports. 
(See Fig. 15) 
Large sheets sag or bend if they are not cor-
rectly supported. If you attempt to cut without 
levelling and properly supporting the work-
piece, the blade will tend to bind, causing 
kickback. (See Fig. 16) 
• Don’t support the material away from the 
cut. 
Cutting thin or corrugated materials; 
Cut thin and corrugated materials at least 1 
from the edge of the workpiece to avoid in-
jury or damage to the tool caused by thin 
strips of metal being pulled into the upper 
guard. 
•Use sharp blades only. Clean and sharp 
blades minimize stalling and kickback.

WARNING 
To prevent the risk of serious personal injury: 
• When making an incomplete cut or cutting is interrupted, or blade is binding or cutter is stalling; re-
lease the power switch immediately and hold the cutter motionless in the material until the blade 
comes to a complete stop.   
• To avoid kickback, never attempt to remove the cutter from the work or pull the cutter backward while 
the blade is in motion. Make sure the blade has come to a complete stop, then remove cutter from 
cut.  
• To resume cutting, start cutter, allow the blade to reach full speed, reenter the cut slowly and resume 
cutting. 
1. Place the wider part of the shoe on the part of the work piece which is solidly supported (See Fig. 17), 
never on the section that will fall off when the cut is made. (See Fig. 18)   
  Hold the cutter firmly to prevent loss of control. Working carelessly can cause severe personal injury. 
  
 
  Fig. 17  Fig. 18 
2. Make sure the blade stops. 
  Even though your tool has a brake, before setting the tool down, make sure the blade has come to a 
complete stop and the lower guard has closed. 
3. Do not use if anything seem unusual. Remove battery pack immediately. 
 If the tool body becomes very hot, or does not work properly, remove the battery pack and do not use. 
Have it checked by an authorized service center. 
WARNING 
To prevent the risk of serious personal injury or fire, do not try to repair the tool by yourself. Never 
disassemble or modify the tool body. There are no user-repairable parts inside. 
4. NEVER ALLOW THE CUTTER TO COME IN CONTACT WITH YOUR BODY. 
  After completing a cut, do not allow the cutter to brush against your leg or side.   
 Since the lower guard is retractable, it could catch on your clothing and expose the blade. Keep 
clothing away from tool. Be aware of the exposed blade sections that exist in both the upper and 
lower guard areas. 
WARNING 
Because cutting metal creates sparks; 
• Always use safety goggles. 
• Do not use tool near any flammable substance or in an area where flammable substances are used. 
Fire and burn injury could result. 
5. Never engage the spindle lock while blade is running, or engage in an effort to stop the tool. Never 
turn the switch on when the spindle lock is engaged. Serious damage to your tool will result.

Charging 
Cautions for the Li-ion Battery 
Pack 
• If the temperature of the battery pack falls 
approximately below −10°C (14°F), charging 
will automatically stop to prevent degradation 
of the battery. 
Common Cautions for the Li- 
ion/Ni-MH/Ni-Cd Battery Pack 
•  The ambient temperature range is between 
0°C (32°F) and 40°C (104°F). 
  If the battery pack is used when the battery 
temperature is below 0°C (32°F), the tool may 
fail to function properly.   
•  When charging a cool battery pack (below 0°C 
(32°F)) in a warm place, leave the battery pack 
at the place and wait for more than one hour to 
warm up the battery to the level of the ambient 
temperature.
