General Maintenance

IMPORTANT!

MAINTENANCE, REPLACEMENT OR 
REPAIR OF EMISSION CONTROL 
DEVICES AND SYSTEMS MAY BE 
PERFORMED BY ANY REPAIR 
ESTABLISHMENT OR INDIVIDUAL; 
HOWEVER, WARRANTY REPAIRS 
MUST BE PERFORMED BY A DEALER 
OR SERVICE CENTER AUTHORIZED 
BY SHINDAIWA CORPORATION 
THE USE OF PARTS THAT ARE NOT 
EQUIVALENT IN PERFORMANCE AND 
DURABILITY TO AUTHORIZED PARTS 
MAY IMPAIR THE EFFECTIVENESS OF 
THE EMISSION CONTROL SYSTEM 
AND MAY HAVE A BEARING ON THE 
OUTCOME OF A WARRANTY CLAIM.

This unit must never be operated with a 

faulty or missing spark arrester or muf-

fler. Make sure the muffler is well secured 

and in good condition. A worn or damaged 

muffler is a fire hazard and may also cause 

hearing loss.

Keep the spark plug and wire connections 

tight and clean.

Make sure nuts, bolts, and screws (except 

carburetor adjusting screws) are tight.

Daily Maintenance

Using non-standard replacement parts could 

invalidate your Shindaiwa warranty.



Remove dirt or debris from the engine, 

check the cooling fins and air cleaner for 

clogging and clean them as necessary. 



Carefully remove any accumulation of 

dirt or debris from the muffler or the 

fuel tank. Dirt build-up in these areas 

could cause engine overheating, induce 

premature wear, or create a fire hazard. 



Check for loose or missing screws or 

components. Make sure the cutting 

attachment is securely fastened.



  Check the entire unit for leaking fuel 

or grease. 

  Never repair a damaged blade by 

welding, straightening, or by modify-
ing its shape. An altered blade may 
break during operation, resulting in 
serious personal injury.

  Blades are not interchangeable 

between Shindaiwa edgers and 
trimmer/brushcutter models. 
Operating any unit with a blade or 
attachment not approved for that 
unit can be hazardous and may 
cause serious injury.

 WARNING!
