Thank you for purchasing tools from LESITE brand. Please read
this manual carefully before using this machine, and retain it for
future reference.
Hand Extruder Operation Precautions：
1. Power on hot air blower and control box.
2. Switch the potentiometer of hot air blower to “7”, and set the control box to
350 degrees, preheat machine for 10 minutes.
3. Cut 30cm length welding rod and insert it to input material hole, switch on
extruder button and observe its status (do not stand near welding nozzle to
avoid hurting).
4. If there is melting rod flowing through the welding shoe, please insert the
welding rod to weld (one input hole is working, but not both at same time).
5. Adjust welding temperature depends on melting capacity.
6. It needs to cut welding rod and make sure all welding rod extruded out after
finish job.
7. Switch the hot air blower to “0” to cool down machine for 5 minutes, and
then power off.
8. Clean air inlet and spare parts regularly, keep the tool clean.
Precaution:
LESITE extruders possess motor cold start protection: when the
temperature reaches below 270 ° C, the motor switches off to avoid of
motor damage cause by disoperation；Metabo extruding motor has a tap
positions . It has been set in “G” or “6” position properly. Any adjustment is
not recommended, otherwise, it may cause improper use and motor
damage which caused by large resistance.

2. Product Overview
LST610 serial is a new type of hot air welder which imported foreign advanced
technology, well-developed. It has reached or exceeded the same type
products of oversea, filling the domestic blank. The major components (hot air
gun and drive motor) are made of imported brand-name accessories, stable
performance, long service life; they are two independent systems, one is for
preheating raw material, another is for welding rod extrusion. Reasonable
structure, convenient operation, continuous welding, high working efficiency,
powerful extrusion, to make the weld strength is greatly improved. It is the ideal
product for a variety of thermoplastic welding processing.
This product is with two major components preheating raw materials hot air
part and welding rod’s extrusion part. Hot air part with adjustable temperature
controller to heat automatically and extrusion part with independent
thermostatic heating control system to send hot air independently, It is easy to
adjust extrusion speed and use screw extruding for powerful extrusion
pressure. Using 220v power supply uniformly to weld plastic sheets, tube and
other thermoplastic products, especially for both ends of large diameter hollow
wall pipe, producing pipe and repairing pipe and so on.
Available welding materials: thermoplastic HDPE, PP, PVDF, especially
PE .Do not apply in a conductive plastic (PE-EL), or cause the machine to
produce a conductive short-circuit.
Replacement of the different welding nozzle, can be applied:
1) Plastic container’s welding, stitching, etc.;
2) The large diameter plastic pipe’s welding, repairing, splicing, sealing, etc.;
3) The thicker plastic membranes, geomembrane splicing, patching and so on.

4. Operation procedures:
1) Put the hand extruder on the shelf, install the handle, and plug in the mains
plug.
2) Open the control box switch, welding temperature is generally set at 300 ° C,
when the temperature reach 270 ° C, the motor switches off, you cannot start,
when the temperature reaches 270 ° C, the motor switch is turned on, you can
start properly. Open the hot air machine power switch, thermostat knob,
heated a few minutes to operate.
(3) The right hand pulls the motor switch, the motor starts to rotate. The new
tool noise, probably it mostly is relevant to the resonance between the tool and
the base or the close of the parts inside the tool. To check if the motor is very
smooth, and the internal sound disappears after sending welding rods.
4) It is better to re-standby 5 to 6 minutes after ensuring the motor can be
started. Then put welding rod into machine to operate. Adjust the temperature
carefully depending on the thermoplastic case.
5) Motor’s rotating speed is fast without thermoplastic and will become heavier
when sending welding rod, if become very difficult, please stop, probably
screw heating time is too short or low temperature.
6) Different welding methods require different welding nozzles; our company
provides a standard nozzle.
7) Need pressure on machine then can be pressurized on the welding seam.
Extruding some plastic material to heat nozzle, then make weld surface not
smooth.
8) Welding speed, extruding angle, nozzle structure will determine welding
seam’s looking, but the most important thing is air temperature and air volume.
It determines welding strength. Usually hot air temperature is 260 ~
400 ℃.Certainly, the faster welding speed, the higher required temperature.
9) Hot air with the welder moves. It is alright as long as can make the surface
to be welded after the hot air blowing. The higher temperature of the welding is
not the better. Select the correct temperature is very important.

10) Please do not knock when replace the PTFE welding head. It is better to
heat then take down.
11) Hot air motor carbon brush life is about 800 hours, attention to early
replacement; do not wait until the carbon brushes to run out.
12) When shutdown, please circumgy rate hot air thermostat knob to the
minimum, a few minutes blowing before they shut down the hot air machine.
13) Retain a little of welding rod when shutdown to avoid extruder screw’s
damage.
14) Clean up welding nozzle when shut down.
