(b) Prime the engine by repeatedly depressing the carburetor primer bulb until fuel can be seen flowing through the transparent overflow return tube:

IMPORTANT!

Repeated cranking of the engine with the choke CLOSED (“ “) will lead to engine flooding. If the engine fails to start after several attempts, move the choke lever to the OPEN position and continue cranking.

(c) Push the choke lever upward

(“ closed“ position). (Cold engine.)

(f) When the engine first fires, gradually return the choke to OPEN

(“ ”) position if you have not already done so.

• If the engine stops before the choke is fully open, restart with the choke closed.

• If the engine stops after the initial firing, restart with choke closed.

(g) When the engine starts and is running, set the engine to idle by tapping the throttle lever to release the throttle lock.

Make sure the cutting attachment is clear of obstructions.

WARNING!

Never start the engine from the operating position.

Starting a Warm Engine

14

Operation

Using A Blade

(1) After starting the engine, pull

the throttle lever gradually.

The engine speed increases

and the blade will start

rotating.

(2) When the throttle lever is

released, the engine goes

back to idle speed

automatically.

(3) Operate the machine at full

throttle while cutting. Best

fuel efficiency is obtained by

releasing the throttle when

swinging back after cut.

(4) The blade rotates

counterclockwise. For best

performance and to minimize

being stuck by debris, move

the blade from right to left

while advancing on your

work.

WARNING!

Position the blade so cuts are made between blade’s

8 o’clock and 10 o’clock positions (as viewed from above).

DO NOT cut between the 11 o’clock and 5 o’clock positions.

WARNING!

“BLADE THRUST” is a sudden sideway or backward motion of the machine. Such motion may occur when the blade jams or catches on an object such as a sapling tree or tree stump. BE CONSTANTLY ALERT

FOR BLADE THRUST AND GUARD

AGAINST ITS EFFECTS.

CAUTION!

To prevent possible engine damage, do not allow the machine to run at high speeds without a load. Avoid operating the engine at low speeds. Doing so can lead to rapid clutch wear. In addition, slow-speed operation tends to cause grass and debris to wrap around the cutting attachment.

You may install one of several types of Shindaiwa 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 trimmer head on the ground during operation.



Manual. The operator indexes line manually 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.

Engine Operating Speeds

Operate at full throttle while cutting grass.

CAUTION!

Operation at low rpm can lead to premature 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 trimmer line. Cut grass by swinging the unit's trimmer head from left to right. Keep the trimmer head horizontal.

CAUTION!

Do not push the rotating line into trees, wire fences or any material that could tangle or break line ends.

Maintenance

WARNING!

Before performing any m a i n t e n a n c e , r e p a i r, 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, straightening, or by modifying its shape.

An altered blade may break during operation, resulting in serious personal injury.

Edging

Tilt the handle about 100° to the left (from horizontal) and move forward, holding the trimmer or brushcutter vertically as shown.

Daily Maintenance

Prior to each work day, perform the following:



Remove the dirt and debris

from the engine, check the

cooling fins and air cleaner

for clogging, and clean them

as necessary.



Carefully remove any

accumulations of dirt or

debris from the muffler and

fuel tank. Dirt buildup in

these areas can lead to

engine overheating, fire, 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.

Muffler Maintenance

(350 only)

Hard starting or a gradual loss of performance can be caused by carbon deposits lodged in the muffler’s spark arrester screen.

In such cases, performance can usually be restored by removing the spark arrester screen and giving it a thorough cleaning with a stiff bristle brush.

If carbon deposits are severe or if no performance improvement is noted, your unit should be returned to your Shindaiwa dealer for inspection.

Muffler

Remove the cutting attachment and the gear shaft collar, and press new grease into the gear case until the old grease has been pushed out. Use only lithium base grease (such as Shindaiwa Gear Case Lubricant).

12-6 50 Hour Maintenance

10/15 Hour Maintenance

Remove and clean the spark plug.

Adjust the spark plug electrode gap to 0.6 - 0.7mm. If the plug must be replaced, use only NGK BMR6A.

CAUTION!

Before removing the spark plug, clean the area around the plug to prevent dirt and dust from getting into the engine’s internal parts.

Fuel Filter Maintenance

Use a hooked wire to extract the fuel filter from inside the fuel tank.

Remove and replace the filter element. Before reinstalling the filter, inspect the condition of the fuel line. If damage or deterioration are noted, the unit should be removed from service until you can consult with an authorized servicing dealer.

CAUTION!

Make sure you do not pierce the fuel line with the end of the hooked wire.

The line is delicate and can be damaged easily.

Long Term Storage

Whenever the unit will not be used for

30 days or longer, use the following procedures to prepare it for storage:



Clean external parts thoroughly and apply a light coating of oil to all metal surfaces.



Drain all the fuel from the fuel tank.

IMPORTANT!

All stored fuels should be stabilized with a fuel stabilizer such as STA-BIL™.

Blade Sharpening

With the file or a grinder, file a blade as follows.

WARNING!

Sharpen only the cutting teeth of a blade. DO NOT alter the contour of the blade in any way. In order to keep the blade in balance, all cutting edges must be sharpened equally. DO NOT file the tips of the teeth too sharp.

Make sure the width of the 3 sides/4 sides is all the same.

The sharpening angle should be 45

0

approx.

Do not file the tips of the blade too sharp. Leave 0.2~0.5mm unsharpened.

To remove the remaining fuel from the fuel lines and carburetor and with the fuel drained from the fuel tank.

1. Prime the primer bulb until no more fuel is passing through.

2. Start and run the engine until stops running.

3. Repeat steps 1 and 2 until the engine will no longer start.

CAUTION!

Gasoline stored in the carburetor for extended periods can cause hard starting, and could also lead to increased service and maintenance costs.

The bottom of each tooth must remain unsharpened. (Blade as viewed from bottom)



Remove the spark plug and pour about

7 grams of 2-cycle mixing oil into the cylinder through the spark plug hole.

Slowly pull the recoil starter 2 or 3 times so oil will evenly coat the interior of the engine. Reinstall the spark plug.



Before storing the unit, repair or replace any worn or damaged parts.



Remove the air cleaner element from the carburetor and clean it thoroughly with soap and water. Let dry and reassemble the element.



Store the unit in a clean, dust-free area.
