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 CORP. 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. 

10-Hour Maintenance

Every 10 hours of operation (more fre-

quently in dusty or dirty conditions):


Remove the air cleaner element.  

See Figure 18. Clean or replace as 

necessary. To clean element: wash it 

thoroughly in soap and water. Let it  

dry before reinstalling the element.

CAUTION!
Do not operate the unit if the air  

cleaner or element is damaged, or if 

the element is wet.



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 at-

tachment is securely fastened.



  Check the entire unit for leaking fuel or 

grease. 



Never repair a damaged blade 

by welding, straightening, or by 

modifying its shape. An altered 

blade may break during operation, 

resulting in serious personal injury.



Blades are 

not interchangeable be-

tween Shindaiwa edgers and trimmer/

brushcutter models. Operating any 

unit with a blade or attachment not 

approved for that unit can be hazard-

ous and may cause serious injury.
