c. Motor connection and rotation direction :
Left turn
(Counterclockwise)
Exhaust
XT :
The motor shaft rotation direction is determined when looking from the back of the motor.
When the air supply feeds the left air inlet ("L"), the right ("R") air inlet must be connected to exhaust,
4 - Motor running in
modec motors will deliver their full power only after about one hour (motor running in period). Before starting a new motor or a motor
that's been stored for a long period, insert 3 to 5 oil drops directly into the inlet orifice. Connect it to a properly lubricated air supply
and make successive air pulses. Run it with 6 bars air supply during 5 to 10 minutes before getting "normal" performances.
5 – Motor maintenance
Regular maintenance operation must be carried out at least once per year depending on working conditions for an optimal
performance. Use modec maintenance kits and parts only.

and vice versa.
Corrective actions
1.
Check air supply
Check hose connection
2.
Check and reduce load applied
3.
Pulse air inside the motor)
Rotate the shaft manually or with a plier without exceeding the motor
maximum torque
Rotate the rotor directly (see diagram below)
1.
Check air pressure
2.
Check air flow
3.
Check that the muffler / silencer is clean, adequate and properly fitted
For a reversible motor, check that the orifice opposite to air inlet and/or
exhaust orifice are connected to exhaust
4.
Insert 3 to 5 oil drops in the motor inlet orifice
Reverse inlet and outlet
Check air connections
Right turn
