WARNINGS, CAUTIONS AND NOTES

Warnings and cautions are placed at critical points in this manual to direct the operator’s attention to significant items. They are defined as follows:
WARNING: Failure to comply with a WARNING may result in serious injury or death.
CAUTION: Failure to comply with a CAUTION may result in injury to the operator, or damage to the items involved.

• Observe the following precautions to ensure safety.

WARNING
When the power is turned on, the nozzle temperature reaches 100 to 540°C (212 to 1004°F).
If the unit is mishandled. or fire may result. Please observe the following precautions.

• Do not touch the metal portions surrounding the nozzle, the adjoining plastic portions, or the iron receptacle or iron receptacle holder of the iron holder.
• Do not use the product near flammable items.
• Do not direct the hot air toward personnel or touch the metal parts near the nozzle.
• lnform others in the area that the unit is hot and should not be touched.
• Turn the power off when not in use, or left unattended.
• Before replacing parts or storing the unit, tum off the power and allow the unit to cool to room temperature.
• Observe the following precautions to avoid accidents and damage to the unit.

CAUTION

• Do not strike the handpiece against hard surfaces or otherwise subject it to physical shock. This will damage the quarts glass shield around the heating element, and could damage the heater as well.
• Be sure the unit is grounded. Always connect power to a grounded receptacle.
• Do not disassemble the pump.
• Do not modify the unit.
• Use only genuine Hakko replacement parts.
• Do not wet the unit or use the unit when your hands are wet.
• Remove power cord by holding the plug – not the wires.
• Make sure the work area is well ventilated.
• Do not do anything else that might be dangerous.

PART NAMES & DESCRIPTIONS

USING THE HAKKO 851 (Preparation)

1. Attach the holder

2. Insert iron into the holder

3. Insert power plug into outlet
   • Check to make sure the power switch is set to the OFF position before inserting the power plug.

4.  Adjust blow level and temperature
   Refer to the temperature distri bution charts (p13) and adjust the blow level and temperature using the air flow and temperature con trol knob.

5. Turn on power
   When the power switch is turned on, the heater power lamp will light up.

6. The unit is ready for use approximately two (2) minutes after the power is turned on Attaching and using the nozzle holder:
   Attach the nozzle shelf included with the unit. With the nuts on the nozzles, insert them into the holes in nozzle holder with the tips facing downward, as shown in the figure above.

5. USING THE HAKKO 851 (Desoldering parts)

The unit can be used approximately two (2) minutes after the power has been turned on.

1. Heat the part
   Apply the hot air to the part that is to be removed in order to melt the solder .
   CAUTION: Be careful not to touch the component, etc. with the tip of the nozzle.
   The blow selector switch on the rear of the unit should normally be set to “Hi”. To reduce the blow level, set it to “Lo”.

2. Grap the part, using tweezers While heating the part, use twee zers to grasp the part to be re moved.
   When grasping the part, do so by straddling the sides that are not sol dered. This will help prevent the heat from dissipating.

3. Remove the part
   When the solder has melted, raise the tweezers to remove the part.

4. Remove any remaining solder After the part has been removed, remove the old solder with desoldering wire or other solder removal tool.

5. USING THE HAKKO 851 (Soldering parts)

1. Coat with solder paste
   Coat with a suitable amount of solder paste and mount the part.

2. Preheat the part

3. Solder the part
   Apply the hot air to the section to be soldered and solder it in place.

CAUTION:
If the blow level is too great, the part or the solder may be blown out of place. Reduce the blow level when soldering parts.
CAUTION:
Soldering using hot air has many advantages, but it sometimes results in inadequate soldering.
We recommend that all of the conditions for soldering be studied carefully.

REPLACING THE HEATING ELEMENT

1. Disassemble the air nozzle
   • Remove the cover from the unit.
   • Loosen the packing retainer on the rear of the panel.

2. Disassemble the iron
   • Remove the nut, nozzle and nipple in that order.
   • Slide the tube off of the terminal in the direction indicated by the arrow, then detach the ground ing spring from the sleeve.

3. Pull out the heating element
   • Pull the silicone hose so it is straight and then pull out the heating element from the handle, along with each of the cords.
   CAUTION: When the cords are caught inside the silicone hose and do not move freely, press down on it lightly from above.![HAKKO 851 SMD Rework System

  4. Replace heating element
     • Using a stripper or other desoldering tool, remove the sol der from the soldered section of the terminal, then remove the old heating element.
     • Set the new heating element in place as shown in the figures at right.
     • Solder the lead wire of the heat ing element to the terminal.
     CAUTION: Make sure that the insulation tubes on the heating element lead wires completely cover the lead wires when the heating element is put into place. If the lead wires are showing this will cause the heating element to protrude too far from the terminal board and block the air flow out of the nozzle. CAUTION: Confirm that the distance between the tip of the heating element and the terminal is 82 – 84mm (3.2 in. – 3.3 In.).

  5. Reassemble the iron
     • Attach the grounding spring to the sleeve, then slide the tube back over the terminal.
     • Pull the cord from the air nozzle side to insert the terminal back in the handle.
     • Attach the nipple, nozzle and nut.
     CAUTION: The silicone hose should be straight while this is done. Also, be sure to pull all 3 cords (2 white, 1 green) together.

  6. Reassemble air nozzle
     • Push the packing and cord stop per through the tube and insert in the air nozzle.
     CAUTION: Be sure to push the packing and cord stopper through the tube in order to prevent air leakage.
     • Screw on the packing retainer.
     • Replace the cover on the unit.

  7. Calibrate the temperature
     After replacing the heating ele ment, be sure to calibrate the temperature to ensure accurate temperature control.
     • Attach ø 2.0mm (0.08 in.) nozzle and set the blow selector switch to Hi. Set the temperature con trol knob to “8” and the air flow control knob to “5”, then heat the nozzle for two
     (2) minutes.
     • Using a screwdriver, adjust the CAL control until the temperature of the air 2mm (0.08 in.) from the blow exit aperture 540°C (1004°F).
