Outer pump calibration
Recalibration of the pump is necessary if either of the original gauges have been replaced by another (for any
reason). It is not required if only a gauge scale detail (Label) has been replaced. When recalibrating the pump,
please leave the pump/canister fixed in place on the machine.
Tools required: 1 x Allen (hex) key 3/32” A/F
a. To calibrate the outer plunger, remove the inner
(red) gauge and inner (red) plunger and set the
outer (black) gauge to the zero position.
b. Using the Allen key, undo both calibration
grubscrews until free movement can be felt
between the outer (black) plunger handle and
the outer (black) gauge knob.
c. Carefully wind one grubscrew down until only
slight movement is felt between the outer pump
handle and the gauge knob. Then wind the other
grubscrew down until no free movement can be
felt, being careful not to over-adjust.
