MAINTENANCE 

For  the  motor  make  sure  that  the  end 
plates that abut the cylinder are free from 
burrs  and  sharp  edges  and  if  necessary 
lap on a flat fine grade of abrasive paper.  
 
Press bearing (15) into rear case (26) and 
support the inner race of bearing (15) and 
press  the  non  splined  end  of  rotor  (24) 
into the assembly.  
 
Tap the rotor relative to the rear case and 
bearing  assembly  until  a  clearance  of 
approx.  0.0025”  (0.065mm)  is  achieved 
between the rotor and the rear case.  
 
Ensure  the  rotor  spins  freely  before 
assembling  the  rest  of  the  motor 
assembly. 
 

Reassembly 

Clean all parts and examine for wear. 
 
Use  only  distributor  or  manufacturer 
supplied spare parts. 
 
Particularly  examine  O-rings,  bearings 
and gears. 
 
Coat  all  parts  in  a  pneumatic  tool 
lubricating oil, one preferably containing a 
rust inhibitor. 
 
Grease  bearings  and  gears  with  a 
molybdenum  or  lithium  based  general 
purpose grease. 
 
Reassemble in the reverse order. 

This  machine  has  a  speed  controller  or 
governor, parts (21), (28), (42), (44), (45) 
and (46). 
The correct setting of this speed controller 
is  critical  to  the  safety  of  the  tool  and 
should  only  be  carried  out  by  a  trained 
competent person. 
 
The speed is set by assembling the speed 
controller,  measuring  the  output  spindle 
gear  shaft  (11)  speed  with  a  calibrated 
tachometer. 
 
Adjustment  to  the  spindle  speed  can  be 
made by rotating adjust screw (42). 
 
The speed of the grinder running free with 
an  air  inlet  pressure  of  100  psi  (7  bar) 
measured  at  air  inlet  (57)  must  not 
exceed 7,000 RPM.
