the sealing arm. The sealer will automatically control
the seal time.
3. Once seal is complete, slide the cutter to trim the
bag (only on H-161, H-293, H-963 and H-1252).
4. Release the sealing arm.
NOTE: Uline model #s H-161, H-293, H-963 and

NOTE: Cutter may have a clear, wax coating
that needs to be removed before first use. Use
caution when removing.
NOTE: Uline model #s H-458, H-163, H-190, H-306
and H-1029 do not have cutting blade.
NOTE: Once plugged in, sealer is live. Heat is
only conducted once arm is closed.
CAUTION! To provide continued protection
against risk of electric shock, connect to
properly grounded outlets only.
WARNING! Potential risk of fire or injury. Risk of
electric shock if unit is overturned, overfilled or
if power is not disconnected to clean the unit
or to replace its heating element. Disconnect
the plug from the power source while cleaning
the item or changing its heating element. Keep
children away from this product.
NOTE: Check for calibration:
• Vibrations during shipping may have caused
sealer to fall out of calibration. Must check
heating element and microswitch integrity
before using.
• Heating element must be securely attached
at both ends. Check to ensure looped
around tension rod located near center
hinge.
• If microswitch is properly engaged, user will
hear a "click" after pressing arm down. If no
"click", see troubleshooting guide for more
details.

the longer the heat sealing time. Sealing is
complete when the light turns off.
