Troubleshooting...
Other	 factors	 outside	 the	 tool	 may	 cause	 loss	 of	 power	 or	 erratic	
action.	Reduced	compressor	output,	excessive	drain	on	the	air	line,	
moisture	or	restrictions	in	air	pipes	or	the	use	of	hose	connections	of	
improper	size	or	poor	conditions	may	reduce	air	supply.	Grit	or	gum	
deposits	in	the	tool	may	cut	power	and	may	be	corrected	by	cleaning	
the	air	strainer	and	flushing	out	the	tool	with	gum	solvent	oil	or	an	
equal	 mixture	 of	 SAE	 #10	 and	 kerosene.	 If	 outside	 conditions	 are	
in	 order,	 disconnect	 tool	 from	 hose	 and	 take	 tool	 to	 your	 nearest	
authorized	service	center.
Operation...
Let the tool do the work. Do not put extreme pressure on the
machine.	This	will	only	slow	down	the	speed	of	the	cutting	wheel,	
reduce	cutting	efficiency,	and	put	an	additional	burden	on	the	
motor.	Start	the	tool	off	the	work,	set	it	down	on	the	work	evenly	
and	move	in	the	direction	desired	to	make	the	cut.	When	finished	
cutting,	lift	off	the	work	before	stopping	the	motor. 
NOTE:	During	operation,	safety	goggles	should	always	be	worn	
to	guard	against	flying	rust	and	chips.	Use	only	wheels	rated	at	
20,000	RPM	or	higher.
Air Supply...
Tools	 of	 this	 class	 operate	 on	 a	 wide	 range	 of	 air	 pres	sures.	 It	 is	
recommended	that	air	pres	sure	of	these	tools	mea	sures	90	PSI	at	the	
tool	while	running	free.	Higher	pres	sure	(over	90	psig;	6.2	bar)	raises	
per	for	mance	beyond	the	rated	capacity	and	will	short	en	tool	and	can	
cause	accessory	failure	due	to	overspeed.
Always	use	clean,	dry	air.	Dust,	corrosive	fumes	and/or	water	in	the	air	
line	will	cause	damage	to	the	tool.	Drain	the	air	tank	daily.	Clean	the	
air	inlet	filter	screen	on	at	least	a	weekly	schedule.	The	rec	om	mend	ed	
hookup	pro	ce	dure	can	be	viewed	in	figure	1.
Lubrication...
Lubricate	the	air	motor	daily	with	quality	air	tool	oil.	If	no	air	line	oiler	
is	used,	run	1/2	ounce	of	air	tool	oil	through	the	tool	by	squirting	oil	
into	the	tool's	air	inlet	or	into	the	nearest	connection	to	the	air	inlet,	
reconnecting	air	supply,	and	then	running	tool.	Do	not	use	more	than	
1/2	ounce	of	oil,	as	overfilling	will	reduce	the	performance	of	the	tool.
