CHAPTER 1 SAFETY SUMMARY
1.0 Introduction
This chapter, intended as an introduction to the installation,
operation and maintenance of HS0753 Pressure-Keeping Type Hot
Melt Applicator, sets out the safety rules to be observed for
preventing risk both to personnel and to the equipment.
This risk prevention rules may be classified as follow:
1. Safety during installation.
2. Safety during equipment operation.
3. Safety during maintenance.
4. Safety during use of hot melt solvents.
Failure to follow these recommendations may result in person-
nel injury from burns or electrocution and/or equipment and
property damage.
1.1 Safety During Installation
1. Establish correct and effective ground connection for en-
tire apparatus, without such connection, every element of
the apparatus even those are apparently insulated become a
potential conductor and pose a risk of electrical shock.
2. Check that the power cords and their insulation are corre-
ctly dimensioned for the load constituted by the apparatus
complate with all its accessories.
3. Ensure that a switch with a thermal safety cut-off is in-
stalled between the apparatus and the primary generator.
4. Always operate the apparatus in accordance with the recom-
mended current and voltage.
If the apparatus is operate at voltages and currents other
that recommended this may create potential fire risk.
HS0753-1-01 930906

1.2 Safety During Operation
1. Do not operate the equipment near volatile or otherwise ex-
plosive gases or materials.
2. Do not operate the equipment without the covers, panels and
safety guards properly installed.
3. Do not operate the equipment at a temperature above 50℃ or
below 0℃.
4. If the applicator nozzle device unshielded from the wind.
Rapid heat dissipation due to air movement across the noz-
zle tip may cause operational problems.
5. Do not use the equipment as a ladder or stepping stool.
6. Use only the metal base when attempting to lift or move an
applicator. Do not use equipment covers, doors, panels, as
braces or grips.
1.3 Safety During The Maintenance
The main precautions to be adopted when carrying out mainten-
ance are:
1. Disconnect the electrical power supply before maintenance
the equipment.
2. Do not wear rings, watches, bracelets etc, when carrying out
the maintenance.
3. Do not in any way inspect or adjust any component unless
another person is present and able to ensure immediate as-
sitance in event at accidence.
4. Employ only qualified personnel for maintenance work on the
equipment.
5. Never touch bared connection or components without discon-
necting the electrical power supply while power is on. Dan-
gerous voltage exise at several point in the equipment.
HS0753-1-02 930906

6. Disconnect the electrical supply before removing any pro-
tection case or changing any electrical component.
7. If possible, stand on a rubber insulating mat when carrying
out maintenance on the hot melt applicator. Do not work on
wet floors or in very damp surrounding.
8. Always use protective gloves and clothing which gives the
maximum protection to parts of the body liable to be sp-
lashed by hot melt or come in contact with the hot surface
of components.
9. Before lose or install the pressure connector ensure the
operating pressure of the hot melt applicator is reduce to
zero.
10. Do not use any tools which is with flaming or sharp tip to
clean a hot melt applicator to avoid a injury in the in-
ternal surface of the equipment.
11. Never operate equipment with a known any from of leak (air
or hot melt) in the system.
1.4 Safety When Using Adhesive And Solvents
A. Adhesive
1. Use extreme care when working with molten material. They so-
lidify rapidly at high temperature and present a hazard se-
vere burns can occur if the molten materials first solidi-
fied, they are still hot.
2. Always wear protective clothing and eye protection when
handing molten material or working near equipment con-
taining hot melt adhesive under pressure.
B. Heating Solvents
1. Do not use a open flame or uncontrolled heating device to
heat solvents.
2. Do not use paint-type solvents under any circumstances.
These solvents are volatile and may be a fire and/or toxic-
vapor hazard even at room temperature.
HS0753-1-03 930906

3. Always be sure that work area is adequately ventilated.
4. Avoid prolonged or repeated breathing of solvent vapors.
IF MOLTEN MATERIAL COMES IN CONTACT WITH THE SKIN:
* Do not try to remove molten material from the skin.
* Immediately immerse the affected area in cold, clean water,
keep the affected area immersed until the material has cool-
ed.
* Do not try to remove the cooled material from the skin.
* Cover the affected area with a clean, wet compress.
* In case of severe burns, look for signs of shocks. If shock
is suspected, have patint lie down, use blankets to preser-
ver body heat and elevate the feet several inches.
* Call a physician immediately.

Figure 2.2 Equipment Dimension
2.1 Description Of The Machine Character
The HS0753 Hot Melt Applicator is designed to melt any type or
shape of adhesive with viscosity ranging from 500 to 20000
cps suitable for manual operation.
This equipment has two main system, electrical control system
and heating system including hydraulic system and pneumatic
system.
The solid form hot melt material is melted in a special trat-
ing tank, flow to bottom of the tank and transferred by com-
press air, through the nozzle device for application.
The features of this HS0753 Hot Melt Applicator are:
1. Light weight, small volume, easy to move.
2. Open cap easily, fill materials conveniently and safety.
HS0753-2-02 930906

3. Pneumatic power system.
4. Simple construction, easy to maintain.
5. Pressure and flow are adjustable.
6. Glue melt fast.
7. Glue flow volume can be exactly controlled by electrical
timer.

2.3 Functional Description Of Standard
2.3.1 Power System
The power system of the HS0753 Hot Melt Applicator is pneuma-
tic compress air system. (Refer figure 2.3) The compress air
into the tank, to pressed molten material and outlet from no-
zzle. The quantity of outlet can be control by mane switch or
quantity timer.
2.3.2 Hydraulic System
1. Hot melt tank
The applicator melts adhesives in a Teflon-coated aluminum
tank, in order to avoid the hot melt adhesive adhere on the
wall, become a carbon and difficult to clean the tank. This
tank also able to change hot melt adhesive easily and completely
. In the bottom of the tank sets out a four fins to increase
the heat dissipating rate.
HS0753-2-05 930906

Temperature control is accomplished by means of a resistance
temperature detector (RTD) mounted in the tank wall.
2.3.3 Electrical Power System
1. Heating system
The tank of the HS0753 is electrical heating system. The heat-
er is cover surface of the tank, use a (RTD) temperature sen-
sor to detect the temperature, then transfer the single to the
temperature controller.
2. Temperature controller --- mechanical type controller
Temperature sensor bar contained liquid fully, the volume of
liquid will increase when heated, the additional volume will
force the spring plate of temperature controller through a
pressure tube, the spring plate is opened. When temperature is
rising then switch off the heater and stop heating. When tem-
perature drop down and the spring plate will contact again,
the heater will be switched on and start heating.
CUATION:
The temperature sensor bar of mechanical type temperature con-
trolled must following the condition as below, in order to ma-
intense the properly performance of the sensor.
1. Do not bend or damage the surface of the bar.
2. Do not fold or twist the wire of the sensor.
