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Recalibration of the pump is necessary if either of the original gauges have been replaced by another (for any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. Calibrate the outer pump first by removing the
inner pump (red) gauge and lifting the red pump
handle approximately 4” or 100mm. Lock the
black outer pump gauge into the top hole (zero
position).
b. Using the Allen key, undo the calibration
grubscrew until free movement can be felt
between the outer pump (black) handle and the
outer gauge knob.
c. Carefully wind the grubscrew down until no free
movement is felt between the outer pump handle
and the gauge knob, being careful not to over-
adjust.
When correctly adjusted there should be a
slight binding felt on the black gauge locking pin
(as the locking pin shaft enters the hole in the
gauge).

Inner pump calibration
a. Calibrate the inner pump by lowering red pump
handle fully, then refitting the inner (red) gauge
and setting it to zero.
b. Undo the calibration grubscrew in the red pump
handle until the handle has movement.
c. Carefully wind the grubscrew down until no free
movement is felt between the red pump handle
and the red gauge knob, being careful not to
over-adjust. When correctly adjusted there
should be a slight binding felt on the red gauge
locking pin (as the locking pin shaft enters the
hole in the gauge).
