–	 Check	if		you	have	a	specified	backer	pad	and	polishing	discs.
– Never use cracked, chipped, or any damaged backer pads or polishing  
discs.
–	 Follow	 the	procedures	 specified	in	the	 instruction	 manual	to	properly	 attach	
applicable accessories.
5.  Check the power outlet.
–  When the plug of the power supply cord is easily pulled out of the power outlet, the 
outlet should be replaced.  for such task, consult an electrician.  If the power outlet 
is used on a continuous basis, it may overheat and cause accidents. 
6.  Perform test runs.
  WARNING!
1.  before turning the switch oN, make sure the rotating parts are not touching    
anything. If the switch is turned oN while they are in contact with anything    
else,	the	disc	may	get	damaged	and	it	may	cause	injuries.
2.  When a new disc is attached and the switch is turned oN, keep your body    
well away from the exposed sides of the disc for a moment until the poli\
sher    
reaches its full speed.
It is very dangerous to perform polishing operations using cracked, chipped or damaged 
discs. before starting polishing operations, keep the wheel away from anyone nea\
rby. be 
sure to perform a few test runs to check whether there are any abnormali\
ties.
Test run duration: •	After replacing a polishing disc……………………at least\
 1 minute
•	 before starting operations each day...................at least 1 minute.

1.  backer Pad Attachment 
 Procedures  (figure–1)
a)  Place the polisher upward to attach the 
backer pad onto the spindle.
b)  slide the wrench into provided slot located  in the front of polisher to lock the spindle 
and proceed tightening the backer pad.
c)  Remove the wrench.
d)  Center and attach the polishing disc onto the backer pad by securely pre\
ssing onto 
the  attachment.
e)  Cut rubber guard according to your needs.
  Note:  If using the Alpha
®	Twistouch	 Turbo	system	 for	flat	 area	
applications	 together	with	the	flat	polishing	 caster,	a	“SPACER	
RING” 	may 	be 	needed 		 to	 be	placed	 between	 the	spindle	 of	
AWP and Twistouch Adapter to level the height of the Twistouch 
Turbo	abrasives	with	the	flat	polishing	caster.)
 
2.  Attaching the water hose. (figure–3)
a)	Attach	 the	polisher	 water	hose	fitting	 to	a	
regular 	garden 	hose	 by	tightening 	the	 fitting. 	
The	 polisher	 water	hose	fitting	 will	fit	on	 any 	
garden hose.
3.  Attaching the C handle (handle A).  
  ( figure -4) The C handle (handle A) delivers 
better control and stability of the polisher when 
used with any of the following accessories; 
flat	polishing	 caster,	core	drill	bit	or	Twistouch	
Turbo.
a) slide the C handle (handle A) onto the gear  case and match  the holes pattern.
b)  Insert provided two screws (M8X16) into the 
holes and tighten them to securely attach 
the C handle (handle A) onto the gear case.
  Note:  Do not overtighten the two screws  (M8X16).  Doing

so you will risk stripping the threads.
4.	 Attaching	the	flat	polishing	caster.	
	 The	 flat	polishing	 caster		was	designed	 to	aid	
polishing	 flat	surfaces.	 To	perform	 properly	
such application you need to have the C-handle 
(handle A) mounted.   (figure- 5)
a)  open the metallic strap to place the auxiliary 
frame onto the motor. Make sure the water 
pipe	 matches	 the	two	 slots	 located	 at	the	 base	 of		flat	 polishing	 caster.	The	
rollers should face the same position as the spindle.
b)	 lock	 the	metallic	 strap	around	 the	motor	 to	securely	 attach	the	flat	polishing	
caster.

  DANGER!
	 1.	 During	operation,	be	sure	to	wear	personal	safety	equipment.
 2. If you accidentally drop the polisher, do not use the polisher until 
    checking that it is not cracked, deformed, or damaged.  Check the 
    polishing disc as well.
 
before plugging  the power supply cord into the power outlet, make sure t\
he switch is turned 
off.  If you plug in the power supply cord without realizing the switch is turned oN, the 
polisher will start and it may cause an accident.
1.  Water valve operation
–	 Turn	ON	the	water	valve	lever	to	allow	water	to	flow	through	the	polisher.	
2.  switch operation – Push the switch lever forward to start the polisher. Wait until the motor has 
reached its constant RPM (revolutions per minute).
3.  Polishing procedure
–  When the polishing disc comes into contact with the workpiece make contact 
slowly. 
–  Proceed polishing in a desired pattern using all polishing discs in reco\
mmended 
sequence.
4.   Applying force onto the polisher
–  Do not apply more force onto the polisher than the force created by the
  weight of the polisher itself. The polishing disc is designed to work properly 
under light weight. 
–   Applying excessive force or pressure may damage the disc and could shorten 
the machine’s service life.  such action will decrease rotation speed, which reduces the 
efficiency	of	polishing	action	and	jeopardize	polishing	results.
  CAUTION!
5.  Precautions immediately after use.
–  After using the polisher, turn off the switch.
–   once the disc stops rotating completely, put the polisher in a safe place.  It may 
cause a unexpected accident if you touch the disc before the disc stops rotating.

		GROUND	FAUlT	CIRCUIT	INTERRUPTER:
A	Ground	 Fault	Circuit	 Interrupter	 (GFCI)	is	mounted	 at	the	 end	 of	power	 supply	 cord.		The	
GFCI	 goes	OFF	when	 water	 enters	 inside	the	tool’s	 housing	 preventing	 the	operator	 from	
electric shocks. 
  DANGER!
When	 the	GFCI	 goes	OFF,	the	Reset	 button	 pops	up.	This	 is	
the result of water entering the polisher housing.  Turn off the 
power switch and blow dry air inside the motor cover through 
the	 air	vents.	 Press	the	GFCI	 Reset	 button.	 	 The	polisher	 is	
ready to start  working after the reset  button is pressed down. 
(figure-6)
  WARNING!
1.	 Do	not	remove	the	GFCI.		
2.				Check	items	below	when	the	GFCI	goes	OFF	frequently.
	 •	 Force	applied	on	the	polisher.
	 •	 Water	entered	inside	the	polisher.
	 •	 voltage	drop	due	to	sharing	the	same	power	source	in	work	area.
MAINTeNANCe  AND INsPeCTIoN 
  DANGER!
before servicing the polisher, turn the switch off and unplug the power supply  
cord from the power outlet.
1. Check the attaching screws.
–  before starting any operation, inspect polisher for loose screws.
–  If  the polisher is used with loose screws, it is dangerous. be sure to tighten them.

2. Checking the carbon brushes.
–  Carbon brushes are located inside the motor . They wear out over time     
based on polisher usage.
–  If a carbon brush is worn out, it may cause the motor to malfunction or \
fail.     
  Whenever the length of the carbon brush reaches the wear limit , replace\
 it   
  with a new one.
	 •	 Keep	 the	carbon	 brush	clean,	 so	it	can	 slide	 freely	 in	its	 brush	 holder.  
  CAUTION!
 
  HoW T o RePlACe CARboN bRUsHes
When replacing used carbon brushes 
with new ones, be sure to use only Alpha® 
genuine carbon brushes.  
1.    Disassemble.
–  Remove the grounding screw from 
rear of the motor to release ground-
ing wire. 
–  Remove all screws from the rear 
of the motor to release water line 
mounting plate.  
–  slide out the motor cover.
–  locate the carbon brushes and  pull the torsion spring with needle nose pliers. While holding the torsi\
on 
spring, pull out the carbon brush.
–  Pull the solderless connector on the carbon brush off of the terminal.
2.    Assembly.
–  Replace worn out carbon brushes with new ones and proceed assembling    
 in reverse order described above.
  CAUTION!
Do not pull the carbon brush out of its holder by the pigtail while the torsion spring is loaded, 
doing so will damage the torsion spring.
	 •						 After	installing	the	new	carbon	brushes	place	the	motor	cover	and	tighten	 		
  the screws.
If dust or dirt settles inside the motor, it may cause the polisher to malfunction.  After 
50 hours of operation, run the motor in no load mode and blow dry air th\
rough the 
vents of motor body.  This is effective for removing dust or dirt.

3. Cleaning the surface of the polisher.
–	 Do	 not	use	 paint	 thinner,	 gasoline	 or	any	 flammable	 fluids	to	clean	 the	polisher.		 It	
may cause damage to its surface.  Use a dry or damp cloth with a mild de\
tergent 
dissolved in water. 
4.  store the polisher and parts in a safe place. Do not store the polisher in following areas.
– Where children can reach the polisher. 
–  Where it can be easily tampered with.
