Start-Up
1. Set air pressure to zero.
2. Set any speed restrictor valves to the fully open position
3. Slowly increase air pressure until the shaft rotates under load.
4. For low load applications, increase air pressure by a further 1 –1.25 bar (15 –20
psi). This may not be necessary for high load applications.
5. Adjust the speed restrictor to give the required speed.
6. The air engine will now be running at the optimum and most efficient setting.
Note: It is bad practice to apply excessive line air pressure and then have a tight restriction on the
exhaust port. This can cause excessive wear on the base of the pistons.

Maintenance Procedures
Autoquip Piston Air Engines™are precision engineered and are designed for a long
working life. The wearing parts are the pistons, cylinder liners and seals, which can be
replaced as part of a routine maintenance schedule.
For this purpose, spare parts kits can be purchased from Autoquip Automation or our
authorized distributors, comprising three pistons, three liners, three piston seals and
three O Rings.
The drive shaft and rotary valve assembly are matched during manufacture and should
not be removed from the engine body. If they are removed, they will require
replacement with new parts in our factory.
As with all precision engineered machines, cleanliness is essential during dismantling
and assembly. Before dismantling, the air supply ports must be covered with plastic
caps and the workbench should be clean and free of debris.
