Maintenance

WARNING!

Before performing any main-

tenance, repair, or cleaning

work on the machine, make

sure the engine and cutting attachment

are completely stopped. Disconnect

the spark plug wire before performing

service or maintenance work.

WARNING!

Never repair a damaged

blade by welding, straighten-

ing, or by modifying its shape. An

altered blade may break during op-

eration, resulting in serious personal

injury.

Prior to each work day, perform the

following:

 Remove the dirt and debris

from the engine, check the

cooling ns and air cleaner

for clogging, and clean them

as necessary.

 Carefully remove any

accumulations of dirt or

debris from the mufer and

fuel tank. Dirt buildup in

these areas can lead to

engine overheating, re, or

premature wear.

 Check for loose or missing

screws or components. Make

sure the cutting attachment

is securely fastened.

 Check the machine for

leaking fuel or grease.

Daily Maintenance

You may install one of several types of Shin-

daiwa trimmer heads on your TC350/B450

trimmer or brushcutter, each with features

for speciﬁc applications and/or operational

requirements.

For proper operation, always refer to the

instructions accompanying the trimmer

head being used. Available trimmer head

styles include:

 Semi-automatic. Trimmer line is

indexed when the operator taps the trim-

mer head on the ground during opera-

tion.

 Manual. The operator indexes line man-

ually with the grass trimmer stopped.

 Fixed. The operator must stop the unit

and add new lengths of trimmer line

manually.

 Flail. This device, designed for clearing

weeds and light brush, features three

nylon blades attached to the head by

pivots.

CAUTION!

Do not push the rotating line into trees,

wire fences or any material that could

tangle or break line ends.

Using a Brushcutter With a Trimmer Head

CAUTION!

Operation at low rpm can lead to pre-

mature clutch failure.

Trimming and Mowing Grass

Hold the grass trimmer so the trimmer

head is angled slightly into the area to be

cut. To ensure maximum trimmer-line

service life, cut only with the tip of the trim-

mer line. Cut grass by swinging the unit's

trimmer head from left to right. Keep the

trimmer head horizontal.

Engine Operating Speeds

Operate at full throttle while cutting grass.
