WARNING
USE OF EXCESS PRESSURE CAN CAUSE THE HS-4-C MACHINES
TO BECOME LOCKED IN A CLOSED POSITION AND DIFFICULT TO OPEN.
EXTREME PRESSURE MAY SEVERLY DAMAGE THE MACHINE.
Normally, higher pressures will produce more eective heat seals. However, the use of
excess pressure may force adhesive through the fabric, with an undesired result.
Diculy in locking the Seal Arm Handle of the HS-4-C machine in a closed position is
anindication of too much inter-platen pressure. To preventexcess pressure when sealing
thick garments, screw the Lower Press Platen all the way down. A Lower Press Platen that is
worn from use can cause insucient inter-platen pressure.
The Lower Press Platen should be replaced with Lower Press Platen SPA43941.
When the pressure is too high, preventing the machine to open by itself, this has to be done
manually. After this, switch o the machine for 5 seconds and switch it on again, resetting
the machine.
