●Do not use this pneumatic tool in places with an WARNING explosion hazard. NEVER use the pneumatic tool in places with explosion and fire hazards. Doing so could induce a hazardous situation. ●Pay careful attention to the work in high places To prevent accidents resulting from the drop of the pneu- matic tool, take drop preventive measures such as use of safety wire to work in high places using the pneumatic tool.
Page 15
WARNING ■Basic precautions for use of this pneumatic tool: ●Pay careful attention to work. Hasty or thoughtless action or using the pneumatic tool when you are tired could result in injury or accidents. Use the pneumatic tool with your eye kept on and careful attention paid to it.
Page 16
●Securely mount air hose attachments. Disconnection of the air hose could cause it to fly about due to air jet, thus inducing an imminently hazardous situation. To avoid that, securely mount the air hose attachment to the air hose and the pneumatic tool, respectively.
Page 17
●Do not work in an improper body posture. Use the pneumatic tool in a stable working posture by securely holding it to be ready to respond to unexpected movement. ●Take a break as appropriate. Continuous work for an extended period of time could result in illness.
Page 18
■Maintenance, check, and repair WARNING ●Pay the adequate consideration to store the pneu- matic tool. Unless the pneumatic tool is used, store it in the dry place beyond children’s reach, giving it the enough maintenance. ●Lubrication is important. As the result of lubrication, the premature wearing can be prevented and appearance of rust also can be restricted on the air motor part, gear and so on.

Warnings and Cautions for Safe Use of Pneumatic Drill This drill is a pneumatic tool designed to drill holes in iron sheets, alumi- num sheets, sashes, etc. ■Using the pneumatic drill for any applications other than those specified could result in serious accidents. To avoid that, be sure to thoroughly read this Instruc- tion Manual and fully understand the instructions before use to insure proper use.
Page 24
●Do not use a drill beyond the drilling capacity. Using the pneumatic drill in overload could increase reac- tion to cause you to wobble about, thus leading to personal injury. Furthermore, that could result in damage to the drill. ●Note that small-diameter drills are fragile. Broken drill could come off and fly to cause personal injury.
