The following items should be checked daily, once 
during a shift, or as required for the application: 

•  Air Filter - Check air filter and release any water 

circuit water trapped in the base of the filter. 

•  Tanks – Check material levels and refill as 

necessary.  Verify the material reservoirs are 
vented properly. 

•  Air Dryer - Check the condition of the desiccant air 

dryer, and replace if necessary. 

•  Pump Shafts – Clean both pump shafts with 

solvent and lubricate with approved lubricant such 
as mesamoll or Silicon oil.  

•  Dispense Head – Dismantle, clean thoroughly and 

re-assemble.  Lubricate all parts with a thin coat of 
approved lubricant, or silicon oil. 

•  Ratio Check – If material ratio is critical for the 

application, implement the ratio check procedure as 
required. 

When software in the HMI or Fluid Control Module 
(FCM) needs updating, a black Graco update token is 
used. 

 

To transfer an updated software program from the 
token to the PR70 HMI or FCM: 

1.  Turn OFF the AC power switch in the back of the 

machine.   

2.  If updating the Fluid Control Module (FCM), open 

the access door to the FCM by loosening the 2 
access screws.  Remove the Blue Run token from 
the FCM. 

3.  If updating the Human Machine Interface (HMI), 

remove the HMI from the mounting bracket and 
remove the back cover by removing the 4 screws on 
the back of the enclosure.   

4.  Insert a black programming token into the slot 

provided.  Make sure it snaps into place when 
inserted. 

5.  Turn ON the AC power switch.  

6.  Verify the red LED on the FCM or HMI starts 

blinking at a fast steady rate, then the red LED 
stops flashing accordingly.   Verify the Green LED is 
on continuously, and the amber LED blinks every 
few seconds. 

7.  Turn OFF the AC power switch. 

8.  Remove the programming token from the FCM or 

HMI.  If the second electronic component needs 
updating, insert the token into the other electronic 
module.  If the FCM was re-programmed, re-insert 
the blue run token in the slot provided. 

9.  If programming a second electronic module, repeat 

steps 5 through 8. 

10.  Re-apply machine power. 

11.  Go to the M4 screen to verify the new software 

revision(s). 

The PR70 Fluid control module (FCM) contains a blue 
run token, installed in the socket provided.  It has 
identical appearance to the black programming token, 
but is blue. 

If the token is not installed into the FCM, the machine 
will not operate, and an E13 error will be generated on 
the display module.  Hence, if the FCM software is 
updated, it will need to be re-installed at the end of the 
re-programming procedure.
