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 ECHO, INC. THE USE OF PARTS THAT ARE NOT EQUIVALENT IN PERFOR- MANCE 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.

NOTE:

Using non-standard replacement parts could invalidate your Shindaiwa warranty.

WARNING!

Before performing any mainte- nance, repair, or cleaning work on the unit, make sure the engine and cutting attachment are completely stopped. Disconnect the spark plug wire before performing service or maintenance.

WARNING!

Non-standard accessories, cut- ting attachment, or replacement parts may not operate properly with your unit and may cause damage and lead to per- sonal injury.

Muffler

Cutter blade adjustment

Spark Plug

Keep the spark plug and wire connections tight and clean.

Fasteners

Make sure nuts, bolts, and screws (except carburetor adjusting screws) are tight.

WARNING!

The cutter blades are very sharp! Always wear gloves when working around the cutter assembly.

Cutting performance of your machine depends a great deal on proper cut- ter blade adjustment. Properly adjusted blades will oscillate freely yet help pre- vent binding of cut material between blades. Adjust blades as follows:

1.Loosen all blade locknuts at least one full turn.

2.Tighten each blade shoulder bolt firmly, and then loosen the shoulder bolts 1/4 to 1/2 turn.

3.Working from the gearcase end, lock each bolt in place by firmly tighten- ing its locknut while preventing the shoulder bolt from turning.

When shoulder bolt adjustment is cor- rect, there should be a gap of 0.25–0.50

mmbetween the cutter blades and the flat washers, and the flat washer beneath each bolt head should turn freely.

CAUTION!

Operating the trimmer with worn or improperly adjusted cutters will reduce cutter performance and may also damage your machine. Never operate the machine with damaged or worn cutters.
