MAINTENANCE

SPARK ARRESTOR

The muffler is equipped with a spark arrestor screen inside 
muffler body. After extended use the screen can become 
dirty and the screen may need to be replaced by an autho-
rized servicing dealer.

WARNING:

To avoid a fire hazard, never run the blower without the 
spark arrestor in place.

CLEANING THE EXHAUST PORT AND MUFFLER

Depending on the type of fuel used, the type and amount of 
oil used, and/or your operating conditions, the exhaust port, 
muffler, and/or spark arrestor screen may become blocked 
with carbon deposits. If you notice a power loss with your 
gas powered tool, you may need to remove these deposits 
to  restore  performance.  We  highly  recommend  that  only 
qualified service technicians perform this service.

FUEL CAP

The fuel cap contains a non-serviceable filter and a check 
valve.  A  clogged  fuel  filter  will  cause  poor  engine  per-
formance.  If  performance  improves  when  the  fuel  cap  is 
loosened, the check valve may be faulty or filter clogged.  
Replace the fuel cap if required.

WARNING:

A leaking fuel cap is a fire hazard and must be replaced 
immediately.

SPARK PLUG 

This  engine  uses  a  Champion  RCJ4  with  0.63  mm
(0.025  in.)  electrode  gap.  Use  an  exact  replacement  and 
replace annually.

STORAGE (1 MONTH OR LONGER)

n

  Drain all fuel from the tank into a container approved for 

gasoline. Run engine until it stops.

n

  Clean all foreign material from the blower. Store it in a 

well-ventilated place that  is inaccessible to children. Keep 
away from corrosive agents such as garden chemicals 
and de-icing salts.

n

  Abide  by  all  Federal  and  local  regulations  for  the  safe 

storage and handling of gasoline. Excess fuel should be 
used up in other 2-cycle engine powered equipment.
