CHAPTER 1 SAFETY SUMMARY
1-1 INTRODUCTION
This chapter is to provide related safe precautions while doing
installation, operation and maintenance of Roller Coater (HS7003B-BA)
to prevent personal and equipment’s risk. These safe precautions can
be classified as following:
1.1 Safety during installation
1.2 Safety during equipment operation
1.3 Safety during maintenance
1.4 Safety during use of hot melt adhesive and solvent
1-2 SAFETY DURING INSTALLATION
1) A correct and effective grounding wire must be installed when
installing this roller coater. Without it, any isolation
component would still be conductive, resulting in shock hazard.
2) Check whether the power cords and their isolation protection match
requirement according to the load of the roller coater and its
accessories.
3) Ensure that wire of main power is installed correctly the breaker
from outside.
4) Ensure that the roller coater is working under the proper voltage.
Using wrong voltage may burn this roller coater.
1-3 SAFETY DURING OPERATION
1) Avoid operating the roller coater near the volatile or explosive
materials and gases.
2) DO not operate the equipment without the covers, panels and safety
guards properly installed.
3) Do not operate the machine when the ambient temperature is below
0 or above 50 . ℃ ℃

1-4 PRECAUTION DURING OPERATION
1) Do not use the equipment as a ladder or stepping tools.
2) Avoid some sharp tools or some impurities damaging the surface
of roller while cleaning.
3) Please start the motor after making sure HMA of tank is melted
completely.
4) Use only the metal base when attempting to lift or move applicator.
Do not use covers, doors, panels, braces or grips of equipment.
5) If accident occurs, like finger or some stuff are rolled by roller,
please immediately press the emergency stop switch to stop
machine.
6) Do not wear gloves while operation to avoid hand being rolled
by roller.
1-5 SAFETY DURING MIANTENANCE
The main precautions to be adopted when carrying out maintenance 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 to disassemble or adjust any component of
equipment unless another person who can provide immediate
assistance is nearby.
4) Only qualified person can do maintenance on the equipment.
5) Do not touch bare connection or component without disconnecting
the electrical power supply while power is on. Dangerous voltage
exists at several points in the equipment.
6) Disconnect the power supply before removing any protection case
or changing any electrical components.
7) If possible, please stand on a rubber insulating mat when carrying
out maintenance. Do not work on wet floor or in very damp
surrounding.
8) Always wear the protective glasses, clothing and heat-resistant

gloves to avoid being burned by hot surface of components or
molten glue.
9) Do not use any tool that is with flaming or a sharp tip to clean
melting tank to avoid damaging the Teflon coating on surface of
tank.
10) Please stop operating roller coater immediately when the hot
melt glue is leaking out. And inform the qualified people to
maintain.
1-6 SAFETY WHEN USING HOT MELT ADHESIVE AND SOLVENT
A. HOT MELT ADHESIVE
1) The surface of hot melt adhesive would be solidified immediately
at normal temperature. However, molten adhesive inside is still
high temperature.
2) Always wear protective glasses, clothing and heat-resistant
gloves when load hot melt adhesive into tank or operate machine
close by.
B. SOLVENT
1) Do not use an open flame or uncontrolled heating devices to heat
solvents.
2) Do not use solvent that has high volatility to avoid burning and
exploding at high temperature. And this kind of solvent may result
poison air at high temperature.
3) Make sure the working area is ventilation enough before use
solvents.
4) Do not work under using cleaning solvent for a long time to avoid
breathing too much poison air that caused by high temperature.
NOTICE: If skin is touched by molten hot melt adhesive,
1) Do not try to remove the molten adhesive on the skin.
2) Immerse the affected area into cold water until the adhesive is
cooled down.
3) Do not try to remove the cooing adhesive from the skin.

4) Wrap the wound with clean and wet clothing. If the condition of
injury is very serious, please keep the patient’s body
temperature in normal temperature, and send the patient to the
hospital immediately.

2-3 FUNCTIONS
1) HEATING SYSTEM
Heaters in the bottom of tank and inside the roller provide heating
for HMA. Mechanic temperature controller would automatically control
temperature accordingly. Please start the motor after HMA being
melted completely for protection. It will take about 30 minutes to
melt HMA completely.
The tank of this roller coater uses power-heating system. Heaters
and RTD are in the bottom of tank and inside the roller. Temperature
of heating system is detected by RTD, and then transfer signal to
the PID, at last controller will decide whether heat or not
accordingly.
When the power is turned on, the temperature control system will
firstly check the electro-circuit, checking the SSR and RTD are

normal or not. Subsequently run the PID of heating area. On first
time to start the motor everyday, please make sure HMA in tank is
melted completely. It will take about 30 minutes to melt HMA
completely.
2) PID TEMPERATURE CONTROLLER
This PID controller includes many functions, like digits display,
alert, adjustment, etc. Especially for temperature adjustment,
because that temperature is measured by RTD then transfer signal to
PID. PID controller will decide whether heater or not accordingly.
3) DRIVING SYSTEM
The motor could be started after temperature is reaching setting
value. Motor will drive the gears of rollers through chain after
starting. The lower roller is dipped in tank, and the HMA could be
rolled up by rolling. Put the material on roller, and then HMA could
evenly be coated on the surface of material.

CHAPTER 6 MAINTENANCE
6-1 HOW TO MAINTAIN THE MACHINE
1) Please keep surface of machine clean. Do not use volatile
solvent to clean, such as gasoline, toluene, etc.
2) HMA inside melting tank will get charred and aged after a period
of heating, please change HMA regularly for ensuring coating
quality.
3) Please do not run the motor while doing maintenance to avoid
hands being rolled by roller.
4) Once cloth or any impurity fall into melting tank during
operation, please clean it out. Those stuff will affect glue
coating.
5) Always wear the protective glasses, clothing and
heat-resistant gloves to avoid being burned by hot surface of
components or molten glue.
6) Regularly smear some lubricant on chain and gear.
6-2 HOW TO CLEAN THE ROLLER AND CHANGE HMA
6-2-1 THE WAY TO CHANGE HMA
1) This melting tank coated by Teflon, so the surface is
non-adhesive and easy to clean.
2) Heat roller and tank at the same time, and ensure HMA is melted
completely. Then raise the back of machine around 15 degree
to make HMA flow to front of tank, subsequently turn off power
to cool down HMA.
3) When temperature of HMA is down to 50~60℃, take out the HMA
from tank by hands.
4) Please heat the rest of HMA, and then use cloth to clean it.
5) Surface of melting tank coated by Teflon, please do not scratch
it by any sharp tools. It may cause bad separation effect.

6-2-2 THE WAY TO CLEAN THE ROLLER
1) Once cloth or any impurity fall into melting tank during
operation, please clean it out. Those stuff will affect glue
coating.
2) Start the motor with lower speed, and turn the knob behind
machine to increase glue amount.
3) After finishing above steps, impurities will be rolled out by
roller running. And please stop machine and remove impurities
by tools.
6-2-3 MAINTENANCE OF DRIVING SYSTEM
It’s very important to maintain driving system of this machine.
Because this part is close to melting tank, although this part
protected by cover, it is still possible to be stuck by HMA. Driving
system will be affected by HMA being solidified on chain or gear.
Even cause motor or inverter to get damaged. If any HMA on chain,
please clean it right away by tools.
Besides, it is necessary to smear lubricant on chain and gear, and
check if any HMA leakage occurs from tank.
