Preventive Maintenance
Suggestions
The Insta heat seal machines are relatively
maintenance free. For long trouble-free life, the
following preventive maintenance should be
followed:
1.
Do not heat seal items such as buttons, pins,
snaps, or zippers that tend to cut the silicone
rubber pad or scratch the Teflon heat platen.
2.
Periodically clean the Teflon-coated heat platen
with a non-abrasive piece of cloth. Stubborn
stains may be cleaned,
when platen is cool
,
with mineral spirits.
3.
When the heat platen is hot and not in use,
keep in open position (away from the silicone
rubber pad).
4.
To prevent soiling of substrate, periodic wiping
of the entire exterior machine, including
platens, with a clean rag is recommended. If
necessary, use mineral spirits for cleaning a
cold
machine. Since mineral spirits are
flammable, use precautions and keep away
from sparks, flame, or hot heat platen.
5.
The Model 418 machines require periodic
lubrication with a high-temperature, non-
melting grease (MPPL023).
A. Lubricate the post, handle and cam
assembly depending upon usage. (Once
every month if used continuously.)
WARNING
Power cord replacement
should be from the
manufacturer only (because it
requires a specially prepared
cord).
General Maintenance
It is recommended that you have the following
items available:
A. Regular screw driver
B. Phillips head screw driver
C. Small adjustable wrench
D. Needle nose pliers with insulated handle
E. Set of Allen wrenches
F. Grease gun
G. Special high temperature grease MPPL023
With the above items you should be able to
accomplish most repairs.
Replacement of Silicone
Rubber Pads
1.
Make sure heat platen is cool.
2.
Use tube of MPPC006 adhesive to bond
silicone rubber pad to metal platen.
NOTE: Read instructions on the tube package
.
3.
Be sure that the surface of the silicone platen is
clean. Use a
mild
solvent such as
mineral
spirits
.
4.
The pad and metal must be thoroughly dry and
clean, before starting the bonding operation.
5.
Apply adhesive sealant to the metal platen.
Spread a thin even coat and apply pad
immediately. Apply pressure and position pad
making sure that there is no air entrapment.
NOTE: A serrated blade such as used for
laying down rubber floor tiles would be helpful.
6.
Allow to cure overnight under low pressure at
normal room temperature.
