7-INSTALLATION AND SET-UP (continued)
7.12  Box Size Capacity of Case Sealer
At its factory setting, the case sealer handles a 
variety of box sizes.  If larger capacity is needed, 
the machine can be adjusted to accommodate 
larger boxes.   
Refer to Specif cations Section.
Note -  Machines outside the U.S. may be equipped
  with 220/240 Volt, 50 Hz systems, or 
  other electrical requirements compatible 
  with local practice. 
7.14  Initial Start-Up of Case Sealer
After completing the "Installation and Set-Up" 
procedure, continue through "Operation" for tape 
loading and start-up to be sure case sealer is 
properly adjusted to run boxes
7.13  Electrical Connections and Controls
The electrical and pneumatic "On/Off" switch and 
the Push Button Station "Start/Stop" are located on 
the left side of the machine frame (Figure 7-13).  
If desired, for operator convenience, the "On/
Off" and "Start/Stop" switches can be relocated to 
the right side of the machine frame.  A standard 
three conductor power cord with plug is provided 
at the back of the electrical control box for (See 
Specifi cations) electrical service.  The receptacle 
providing this service shall be properly grounded.  
Before the power cord is plugged into outlet make 
sure that all packaging materials and tools are 
removed from the machine.  
Do not plug electrical cord into outlet until ready 
to run machine.
Use of an extension cord is not recommended.  
However, if one is needed for temporary use, it 
must have a wire size of 1.5mm diameter [AWG16], 
have a maximum length of 30.5m [100 ft], and 
must  be properly grounded.

    contact with each other.
2)  Create added stress to the bumper.
3)  Cause a malfunction of the machine.
These events can potentially cause damage to the machine.  
For more information on bumper settings, contact 
your 3M service representative.

    and vehicle traffi c.
•  To reduce the risk associated with 
      impact hazards:
 − Always use appropriate supporting 
  means when working under the upper 
 drive assembly
•  To reduce the risk associated with
  mechanical and electrical hazards:
 −  Allow only properly trained and
