Alpha Tool.Com.HK Limited Stone Cutter ECC125 User Manual

Note:  If you notice any resistance while tightening the carbon brush cap, it is an indication 
that the top plate on the carbon brush assembly is sticking inside the b\
rush cap. 
Continuing to tighten will damage the carbon brush spring.  (Go to step 6 to correct 
this problem) 
5.   Tighten cap until secure as shown in  
Figure 27.
  6.  Remove the cap and carbon brush from the tool, visually check the two parts for 
defects as shown in Figure 28.

BELT REMOVAL AND REPLACEMENT
The Ecocutter incorporates two drive belts (an inner and outer) to pow\
er the fan assembly.  
If the unit is not removing the dust, you will need to inspect the belts, fan assembly, and 
dust	bag	to	find	the	cause	of	the	problem.
Note:	The	Ecocutter	 makes	use	of	a	flat	 belt	 and	 pulley	 system	 that	is	self-centering	 due	to	
the barrel shape of the pulleys.  If the belt is worn or dirty it can ro\
tate off the pulleys, 
(this will be indicated by a loss of suction).
