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.
