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).
7.  Check to see if the two parts move freely by pushing the top plate of th\
e carbon 
brush into the recess on the bottom of the carbon brush cap and rotate.

8.  If the two parts stick together, replace the carbon brush cap and repeat step  7.
9.  If the top plate of the carbon brush sticks in the new cap, you need to \
replace the 
carbon brush and repeat step 7.
10.  Keep trying until carbon brush top plate can move freely inside of the r\
ecess on the 
bottom of carbon brush cap.
11.  When the correct match is found, install in the tool.  
						

							 TESTING THE UNIT FOR FLOW
  CAUTION!
Belts	cannot	 be	tested	 until	inner	 and	outer	 flanges	 and	flange	 bolt	are	installed	 to	hold	 the	
pulley	firmly	in	place,	(otherwise,	belt	and	pulley	will	fly	off	of	the	spindle.)
A simple test can be done to see if the fan unit is working correctly.
1. Disconnect	 the	hose	 and	back	 flow	preventer	 from	the	tool	 and	place	 the	Ecocutter 	
flat	on	a	table	or	workbench.
2. Turn the unit on and hold a piece of paper over the exhaust port, the pap\
er should 
extend and stand up straight when unit is turned on.
3. If	the	 test	 indicates	 a	weak	 or	no	 flow	 condition,	 the	belts,	 pulleys,	 and	fan	
unit	will	need	to	be	checked	to	find	the	cause	of	the	problem.

 (see section for blade installation and removal)
2.	 Set	outer	flange	and	flange	bolt	aside.
3.	 Loosen	 and	remove	 the	five	 side	 cover 	screws	 (M4x15)	 and	set	aside	 as	shown	 in	
Figure  31 and Figure 32.
4.  Carefully pull side cover away from tool and set aside.
5.	 Remove	inner	flange	by	hand	and	set	aside	as	shown	in	Figure	31.
6.  With the inner flange 
removed, unscrew 
phillips head screw from

 INSPECTING AND CLEANING THE BELTS AND PULLEYS 
1. With the belt removed you can now check and clean it using a mild deterge\
nt.  The 
belt will need to be replaced if it is frayed or showing signs of wear.
2. The pulley should also be cleaned.
3. Rotate the pulley by hand to check for bearing play and wear.
4. Make sure to fully clean the inside area of the large pulley, where the pulley meets 
the spindle to prevent slippage.
Clean the dust and buildup 
in this recessed area before 
reinstalling.

 INNER BELT INSTALLATION
1. Install new belt by rotating and pushing outward onto the pulleys as sho\
wn in 
Figure 36.
2. The belt pulley system is self-centering; rotate belt and pulleys togeth\
er for a few 
revolutions by hand.
  CAUTION!
Belts	cannot	 be	tested	 until	inner	 and	outer	 flanges	 and	flange	 bolt	are	installed	 to	hold	 the	
pulley	firmly	in	place,	(otherwise,	belt	and	pulley	will	fly	off	of	the	spindle.).
3.  Reinstall belt cover and secure with phillips screw.
4.	 Replace	 side	cover 	by	 carefully	 pushing	it	into 	place	 and	secure	 with	the	 five	 phillips 	
screws.
5. Gently tighten side cover screws to a snug condition, to 
prevent screw tabs on side cover from breaking off, as shown 
in Figure 37.
6.	 Reinstall	 inner	and	outer	 flanges	 and	flange	 bolt	to	hold	 the	
pulley	 firmly	in	place,	 otherwise	 belt	and	 pulley	 will	fly	off	 of	
spindle

.
2.  Loosen the bolt knob and remove outer cover to expose the outer belt as shown in 
Figure 39.

 OUTER BELT INSTALLATION
1. Before new belt installation; clean the two pulleys and surrounding area\
s.
 Belt pulleys must be clean from dirt and grease before new belt installa\
tion (to prevent 
slippage).
2.  Install the new belt by rotating and pushing outward onto the pulleys as\
 shown in 
Figure 42.
3.  The belt pulley system is self-centering, rotate belt and pulleys togeth\
er for a few 
revolutions by hand.
  CAUTION!
Belts	 cannot	 be	tested	 until	inner	 and	outer	 flanges	 and	flange	 bolt	are	installed	 to	hold	 the	
pulley	firmly	in	place,	(otherwise,	belt	and	pulley	will	fly	off	of	the	spindle.).
Figure-42
4.	 After	 both	belts	 have	been	 checked	 and/or	replaced,	 check	the	unit	 for	flow	 again	 (see
