Putting into Operation

Ensure that the mains voltage is correct!

The voltage of the power source must agree with the value given on the nameplate of the machine. Machines designated for 230 V can also be operated with 220 V.

Switching On/Off

Switching on:

PHG 500-2: To put into operation, slide the switch 3 to position I or II.

PHG 600-3, PHG 630 DCE: To put into operation, slide the switch 3 to position I, II or III.

Switching off:

To switch off, slide the on/off switch 3 to the stop at position 0.

PHG 600-3, PHG 630 DCE: After working for a longer time with high temperature, allow the unit to cool by running in the cold air setting I before switching off.

Thermo-Protection Switch-Off

When the heater is overloaded (e.g. as a result of restricted air flow), the unit switches it off automatically, however, the blower continues to run. When the unit has cooled to operating temperature, the heater is switched on again.

Setting the Air Flow and Temperature (PHG 500-2, PHG 600-3)

The switch 3 can be set to two (PHG 500-2) or three (PHG 600-3) blower steps. Suitable air flow and temperature combinations can be selected according to the applications.

Step	PHG 500-2	PHG 600-3
I	240 l/min, 300 °C	250 l/min, 50 °C
II	450 l/min, 500 °C	350 l/min, 400 °C
III	-	500 l/min, 600 °C

PHG 600-3: The cold air setting I is suitable for cooling a warmed work piece or for the drying of paint. It is also suitable for cooling the unit before placing down or the changing of nozzles.

Setting the Air Flow (PHG 630 DCE)

The air flow can be set with the switch 3 in three steps. In steps II and III, the temperature can be regulated with the temperature button 4.

Step	Air Flow	Temperature
I	150 l/min	50 °C
II	300 l/min	50 ... 630 °C
III	500 l/min	50 ... 630 °C

Decrease the air flow when, for example:

• The surroundings of the work piece should not be heated more than necessary
• A light work piece could be blown away by the air stream.

The cold air setting I is suitable for cooling a warmed work piece or for the drying of paint. It is also suitable for cooling the unit before placing down or the changing of nozzles.

Setting the Temperature (PHG 630 DCE)

In the blower steps II and III, the temperature can be continuously regulated.

After switching to the blower steps II or III, the temperature that was last selected as the target temperature appears in the display 5 marked with ▷ for approx. 3 seconds. The target temperature applies for both blower steps and does not change when switching between steps II and III.

After displaying the target temperature, the actual temperature at the nozzle outlet is shown with blinking ▷ until the selected target temperature is reached.

The arrows ▷ then disappear and the display 5 shows the actual temperature.

The target temperature can be increased in steps of 10°C by pressing the "+" side of the temperature button 4 or reduced by pressing the "--" side of the button 4. Brief pressing of the button increases or decreases the target temperature one time by 10°C. Longer pressing of the button increases or decreases the temperature continuously by 10°C steps until the button is released or the minimum or maximum temperature is reached.

In the blower step I, the pre-set temperature is 50°C. When switching from blower step II or III with higher temperatures to blower step I, a short time is required until the unit has cooled to 50°C. During the cooling period, the display 5 shows the actual temperature at the nozzle outlet.

Working Instructions

Removing the Heat Protector

For working in especially narrow places, the heat protector 2 can be removed.

• Be careful of the hot nozzle! Increased danger of burning exists when working without the heat protector.

To remove or mount the heat protector, the unit must be switched off and have cooled. For cooling, run briefly in the cold setting, if necessary.

Turn the heat protector 2 counter clockwise to remove and clockwise to mount again.

Placing Down the Unit

For cooling of the heated unit or to have both hands free for working, the unit can be placed down in the upright position on the rear housing surface (see Fig. C).

• Be especially careful when working with the upright unit! There is danger of burning on the hot nozzle and the hot air stream.

Working Examples

The letters of the following application examples refer to the illustrations on the fold-out page.

Temperature settings given in the application examples are suggested values that, depending on the material characteristics, can deviate. The distance between the nozzle and workpiece is dependent on the material to be processed.

The ideal temperature should first be ascertained by performing a test. Therefore, begin with a lower temperature setting.

All application examples (except E) can be performed without accessories. However, the use of the recommended accessory parts simplify the work and significantly improve the quality of the results.

• Be careful when changing the nozzle, danger of burning! Do not touch the hot nozzle. Allow the unit to cool. Wear protective gloves.

Bosch stocks an extensive range of accessories (see Bosch Accessories catalogue) which offer a wide range of other applications.

Additional information can be found in popular DIY books.

A Removing paint/softening adhesives

Place on the wide nozzle 6. Soften the paint using hot air and remove evenly using a spatula. Do not heat the paint for too long since this will burn the paint, making it more difficult to remove.

Many adhesives (e.g. stickers) become softer when heated allowing adhesive bonds to be separated or superfluous adhesive to be removed.

Removing paint from window frames Danger of glass breaking!

Use of the glass protection nozzle 7 is essential. On profiled surfaces, paint can be removed using a spatula and brushed off using a soft wire brush.

C Shaping plastic tubing

Place on the reflector nozzle 8. To avoid kinking the tubing, fill the tubing with sand and seal at both ends. Heat the tubing evenly by moving it from side to side.

D Welding plastics

Place on the reduction nozzle 11 and the welding shoe 10. The materials to be welded and the welding rod 9 must be made of the same material (e.g., PVC with PVC). The seam must be clean and grease-free.

Heat the welding seam until it becomes tacky. Please note that the temperature difference between the tacky and liquid state of a plastic is very small. Then feed in the welding rod 9 and allow it to run into the gap so that a uniform bead is produced.

E Shrink fitting

Place on the reduction nozzle 11. Select the diameter of the heat-shrink tubing 12 according to the work piece, for example, a cable lug.

Heat the heat-shrinkable sleeve evenly.

F Defrosting water pipes

Water lines often do not differ in appearance from gas lines. Gas lines are not to be heated under any circumstances.

Place on the reflector nozzle 8. Heat the frozen zone always from the outside to the middle.

Warm plastic pipes as well as connections between pipe pieces especially carefully to prevent damage.

Soft Soldering

For point soldering, place on the reduction nozzle 11; for the soldering of pipes, the reflector nozzle 8. If solder without flux is used, apply soldering grease or paste to the location to be soldered. Warm the location to be soldered for 50 - 120 s depending on the material. Apply the solder. The solder must melt from the work piece temperature. After the soldered location has cooled, remove the flux.

Maintenance and Cleaning

Before any work on the unit itself, pull the mains plug. For safe and efficient working, always keep the unit and the ventilation slots clean.
