Bosch Power Tools 1943 LED manual Double Insulated Tools, Operating the Tool, Extension Cords

Double Insulated Tools

•Double Insulation is a design concept used in electric power tools which eliminates the need for the three wire grounded power cord and grounded power supply system. It is a recognized and approved system by Underwriter’s Laboratories, CSA and Federal OSHA authorities.

IMPORTANT: Servicing of a tool with double insulation requires care and knowledge of the system and should be performed only by a qualified service technician. WHEN SER-

VICE IS REQUIRED USE ONLY IDENTI- CAL REPLACEMENT PARTS.

POLARIZED PLUGS: If your tool is equipped with a polarized plug (one blade is wider than the other), this plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. To reduce the risk of electric shock do not change the plug in any way.

Operating the Tool

Air flow setting:

The air flow is set steplessly with air flow blower speed dial 3. A lower air stage may be required in certain cases, e.g. to avoid over- heating the workpiece's surroundings or to avoid displacing the workpiece if the air flow is too strong. A higher air stage heats up the workpiece more quickly and enables the hot air gun to be held at a greater distance from the workpiece.

ON/OFF switch

I (Cool air stage) 8.8 CFM ª120ºF. For cooling down a hot workpiece or for drying paint.

II (Hot air stage) 17.8 CFM ª1100ºF.

Temperature control (thermo-electronic): The temperature can be controlled steplessly with the setting dial 5 and switch 6 in setting II.

Extension Cords

•Replace damaged cords immediately. Use of damaged cords can shock, burn or electrocute.

•If an extension cord is necessary, a cord with adequate size conductors should be used to prevent excessive voltage drop, loss of power or overheating. The table below shows the correct size to use, depending on cord length and amperage rating on the tool’s nameplate. If in doubt, use the next heavier gauge. Always use U.L. and CSA listed extension cords.

"SAVE THESE INSTRUCTIONS"

If the nozzle is hot or if you wish to have both hands free when working, you can set the tool down in an upright position on its base.

Temperature displays:

The temperature is displayed via LED 4. By carefully controlling the air flow and tempera- ture, very precise work can be performed on temperature sensitive electrical fittings, pack- aging, and other materials.
