21.0 Troubleshooting
Q
Drive Belts will not move;
A
Check that the air supply is connected to both the motor circuit and airbox input.
If this is the case, with the air motor ball valve and flow control valve closed, increase the pressure on
the torque control. Does pressure show on the pressure gauge? If not then this suggests a connection
problem between the input and the regulator.
Now try opening the ball valve, is air ejected from the exhaust? Again if not there is a connection prob-
lem here.
Open the flow control valve so the motor begins to turn, if the motor turns but the drive belts do not,
this would suggest an issue with the motor drive belt.
Q
Cannot achieve a reasonable speed of cable installation;
A
Check integrity of microduct installation
Route too complex
Check cable inserts and seals correct size for cable used.
Is air supply sufficient – 15bar can be maintained on air gauge.
Cable free from entering “Air Steam” – No resistance
Fill ratio of the microduct
Belts slipping – Close Arm not correctly set, there may be contamination on the belts, or belts worn.
