Disconnect the wire connector (C) from the spark plug (D) by pulling and twisting at the 
same time (fig. 18b). 

 

Remove spark plug with spark plug socket wrench. 

DO NOT USE ANY OTHER TOOL 

 

Check electrode gaps with wire feeler gauge and set gaps to .025” (.635mm) if necessary. 

 

Reinstall a new spark plug. 

Note: a resistor spark plug must be used for replacement. 

Note: this spark ignition system meets all requirements of the interference-
causing equipment regulations. 

11  CLEANING AND MAINTENANCE 

11.1 

Sprocket tip lubrication: 

Caution:  the  sprocket  tip  on  your  new  saw  has  been  pre-lubricated  at  the 
factory.  Failure  to  lubricate  the  guide  bar  sprocket  tip  as  explained  below 
will  result  in  poor  performance  and  seizure,  voiding  the  manufacturer’s 
warranty. 

Lubrication  of the  sprocket tip is  recommended  after  25  hours  of  use  or  once  a  week,  which 
ever occurs first. Always thoroughly clean guide bar sprocket tip before lubrication. 
Tools for lubrication: 
The lube gun (optional) is recommended for applying grease to the guide bar sprocket tip. The 
lube gun is equipped with a needle nose tip which is necessary for the efficient application of 
grease to the sprocket tip. 
To lubricate sprocket tip: 

Warning: wear heavy duty work gloves when handling the bar and chain. 

 

Press the stop switch down. 

Note: it is not necessary to remove the saw chain to lubricate the guide bar 
sprocket tip. Lubrication can be done on the job. 

 

Clean the guide bar sprocket tip. 

 

Using the lube gun (optional), insert needle nose into the lubrication hole and inject grease 
until it appears at outside edge of sprocket tip (fig. 19). 

 

Rotate saw chain by hand. Repeat lubrication procedure until the entire sprocket tip has 
been greased. 

11.2 

Guide bar maintenance: 

Most guide bar problems can be prevented merely by keeping the chain saw well maintained.  
Insufficient  guide  bar  lubrication  and  operating  the  saw  with  chain  that  is  too  tight  will 
contribute to rapid bar wear.  To help minimize bar wear, the following guide bar maintenance 
procedures are recommended.
