1. The large meter display represents the 
    Batch Total for each fuel delivery. Before 
    dispensing fuel, reset the  Batch  Total to 
    zero  by turning the reset knob on the side 
    of the meter counterclockwise. (Figure 2)

Your mechanical fuel meter is designed for 
minimum maintenance. Examine the meter 
and other system components regularly for 
leakage. Keep the system exterior clean to 
help identify leaks

Meter is equipped with an internal strainer. 
The strainer should

 

be checked annually or 

whenever low flow is noticed. The meter may 
also require recalibration if actual fuel delivery 
differs noticeably from meter readings. Refer to
the Repair Section for filter and strainer access 
and calibration information.

Clean Strainer

1. Remove the four retaining screws on  the 
    strainer coverplate. Remove the coverplate 
    and trainer. (Figure 3)

NOTE: 

The small display represents the 

          Cumulative Total of all pump deliveries 

2.  To  enhance  meter  accuracy, dispense fuel
     using a quick-open and quick-close method. 
     Avoid choking flow as the tank becomes full.

MAINTENANCE

2.  Using a fine brush, clean the strainer and
     reposition in the housing.

3.  Wipe clean the strainer coverplate O-ring, 
     groove, and the housing. Coat the O-ring 
     with oil or light grease and install in the 
     coverplate groove. (Figure 4)

4.  Hold the coverplate in position and replace
     the four screws by alternately tightening
     screws until the coverplate is firm against
     the meter housing

The meter is accurately calibrated at the 
factory for use with diesel fuel. Due to
differences in viscosity and flowrates,the meter
may require recalibration to measure other 
fuels or to adjust for inaccuracies.

1.  Purge air from the meter and fuel system by
     dispensing fuel into a container until a full 
     flow occurs. Close the nozzle.

2.  Reset the meter counter to zero by turning
     the reset knob counterclockwise.
