CARE OF GUIDE BAR
Uneven	 bar	 wear	 causes	 most	 guide	 bar	
problems.	 Incorrect	 sharpening	 of	 chain	
cutter	and	depth	gauge	settings	often	cause	
this.	When	 bar	 wears	 unevenly,	 it	 widens	
guide	 bar	 groove	 (see	 Figure	 17).	 This	
causes	chain	clatter	and	rivet	popping.	Saw	
will	not	cut	straight.	Replace	guide	bar	if	
this	occurs.
Inspect	guide	bar	before	sharpening	chain.	
A	worn	or	damaged	guide	bar	is	unsafe.	A	
worn	 or	 damaged	 guide	 bar	 will	 damage	
chain.	It	will	also	make	cutting	harder.
Keep	saw	body	clean.	Use	a	soft	cloth	damp-
ened	with	a	mild	soap	and	water	mixture.	
Wipe	saw	body	to	clean.
