WARNING!

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.

Muffler

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.

Spark Plug

Keep the spark plug and wire connec-

tions tight and clean.

Air Filter

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.

Maintenance

WARNING!
Non-standard accessories,

cutting attachments, or replace-

ment parts may not operate prop-

erly with your unit and may cause

damage and lead to personal injury.

NOTE:

Using non-standard replacement

parts could invalidate your Shindaiwa

WARNING!
Before performing any main-

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.

Fasteners

Make sure nuts, bolts, and screws

(except carburetor adjusting screws)

are tight.

Blades

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!

Prior to each work day, perform the following:

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.

Check for loose or missing screws or components. Make sure the cutter

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.

Remove all dirt and debris from the

engine and check the cooling fins.
