Performance
The Sto M-8 Spray Pump is a new type of pump technology, protected with three
different patents. This new technology enables a wide range of Sto products that are
capable of being used for spray or roller applications.
The peristaltic technology (similar as a milling operation) conveys the material by
massaging or pushing.

3.1 Operating the Control Panel
“OFF“ – M-8 is switched off
3.2 Forward
“FWD“ -- M-8 is switched on (Forward) to pump
material through hose.
3.3 Backward
“REV“ – M-8 runs backwards. Necessary to clean
pump or when blockage occurs in material hose.
When pump is run in REV (reverse) this releaves
pressure from the material hose to allow for safe
removal of hoses.

operator.
3.5 Control Safety
24 Volt Circuit Breaker for Remote Control:
Defective remote control cable (short-circuit) engages
circuit breaker automatically.

3.7 Remote Control Use
Remove the dummy plug and connect the remote
control cable. Set M-8 in FWD position. You will now
have control of the pump at the remote on/off switch
located near the nozzle.
3.8 Regulating Operating Pressure
Operating pressure is adjustable. 1 on scale = lowest
pressure, 13 on scale = highest pressure.
The amount of pressure determines the flow of
material.

Connect material hose to M-8. Connect air supply to spray nozzle. Material hoses must
be primed prior to spraying Sto products. Contact StoMachine HelpLine for proper hose
lubricant to be used to prime hose.
Fill material hopper first, turn switch on lowest
pressure level (1). Before turning on pump, make
sure the spray nozzle is open. Turn on the pump.
Note: To operate pump the dummy plug or the
remote cable must be connected.
If M-8 is not pumping material turn pressure switch to next setting, moving only one
setting at a time, until desired material flow is achieved.
Important: Do not stress pump and hoses. Please
use only as much pressure as needed.
Pump aggregated finishes, coatings and other Sto products at maximum flow rate with
lowest possible pressure. To achieve best spray appearance please try first on a small
area.
Float all finishes; some coatings require backrolling.
