Never repair a damaged blade 

 

■

by welding, straightening, or by 

modifying its shape.  An altered 

blade may break during opera-

tion, resulting in serious per-

sonal injury.
Blades are not interchangeable 

 

■

between Shindaiwa edgers and 

unit/brushcutter models.  Oper-

ating any unit with a blade or 

attachment not approved for the 

unit can be hazardous and may 

cause serious injury.

This unit must never be operated with 

a faulty or missing spark arrester or 

muffler. 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 connec-

tions tight and clean.

The H4 engine that powers your 

Shindaiwa model is a hybrid 4-stroke 

engine. As a hybrid, the engine is 

lubricated by oil mixed with the gaso-

line and air from the carburetor that 

moves through and around the inter-

nal parts of the engine in a similar 

way that a 2-stroke engine is lubri-

cated. Without the heavy duty 2-stage 

air filter equipped on all H4 engines, 

dust and dirt could also move through 

the engine, decreasing engine life, 

increasing valve wear and the need 

for more frequent valve adjustments. 

To keep your H4 engine strong and 

reliable, Shindaiwa  recommends that 

you check and service the air filter as 

instructed in the 10-Hour Maintenance 

section that follows.

tenance, repair or cleaning work on 

the unit, make sure the engine is 

completely stopped. Disconnect the 

spark plug wire before performing 

service or maintenance work.

Make sure nuts, bolts, and screws 

(except carburetor adjusting screws) 

are tight. 

Keep blades sharp and check blade 

condition frequently.  If a blade’s per-

formance changes suddenly, stop the 

engine and check the blade for cracks 

or other damage.  Replace a damaged 

blade IMMEDIATELY!

Remove all dirt and debris from the engine, check the cooling fins and air 

 

■

cleaner for clogging, and clean as necessary.
Clean any debris or dirt from the cutting attachment.

 

■

Check the entire unit for leaking fuel or grease.

attachment is securely fastened.
Make sure nuts, bolts, and screws (except carburetor idle speed adjusting 

 

■

screws) are tight.
Carefully remove any accumulations of dirt or debris from the muffler and fuel

tank. Check cooling air intake area at base of crankcase.  Remove all debris. 

Dirt build-up in these areas can lead to engine overheating, fire, or premature 

wear.
