Mufer

This unit must never be operated with

a faulty or missing spark arrester or

mufer. Make sure the mufer is well

secured and in good condition. A worn

or damaged mufer is a re hazard and

may also cause hearing loss.

Spark Plug

Keep the spark plug and wire connec-

tions tight and clean.

Fasteners

Make sure nuts, bolts, and screws

(except carburetor adjusting screws)

are tight.

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 lubricated.

Without the heavy duty 2-stage air l-

ter equipped on all H4 engines, dust

and dirt could also move through the

engine, decreasing engine life, increas-

ing 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 lter as instructed in

the 10-Hour Maintenance section that

follows

Maintenance

Before performing any

maintenance, repair, or cleaning work

on the unit, make sure the engine and

stopped. Disconnect the spark plug

wire before performing service or

cutting attachment, or replacement

parts may not operate properly with

your unit and may cause damage

Daily Maintenance

Carefully remove any accumula- ■

tions of dirt or debris from the muf-

er and fuel tank.

or components. Make sure the

attachment is securely fastened.
