CARE AND MAINTENANCE

 

 

The KF-250 is a precision machine. It is very important to keep it free of excessive dust, dirt and 
foreign matter. We recommend that you keep the machine covered when not in use.  

 

BEARINGS/BUSHINGS:

 

The bearings are sealed roller bearings and are designed to be self 

lubricating.  However, dirt and dust can get into them causing clogging and dirt build up. It is 
recommended to oil them weekly under heavy use or monthly under light use. The bushings for 
the knife blades are Bronze and require lubrication more frequently.  Oil these once a week 
under heavy use with a light machine oil or 3-1 oil. 

 

SENSOR EYE:

 

Clean the lower reflector tape located on the plate under the infeed register 

regularly. Clean with water damp rag only. Dust will cause the beam to reflect incorrectly. Clean 
when necessary.

 

 

KEEP THE ROLLERS CLEAN:

 

Excess paper dust will cause slippage of the paper.  You must 

clean the rollers regularly to ensure good registration.  To do this, unplug the machine carefully, 
lift plastic cover, and use a clean wet rag with water only and clean each roller. If you do keep 
your KF-250 clean and in top condition, it will give you years of service.

  

IMPORTANT NOTES BEFORE OPERATING THE KF-250

 

 

To ensure the smooth operation of this machine please read the following.  If you do not 
understand these sections of how to operate the machine you may cause damage and 
unintentionally void your warranty. 

 

DOUBLE FEEDING:

 

The KF-250 is designed to run a single sheet. If a double sheet is fed 

through the machine, it will lock up.  If the machine is not turned off immediately, you may 
cause damage to the motor driver and void the warranty. 

KNOB SETTINGS:

 

The knob settings are directly related to how well the machine will run.  

Please read the section on Knob settings before operation.  

START DELAY:

 

When pressing the RUN button there is a 2 second delay for the transport 

motor to turn as the knife blades preform a homing cycle.
