Idle Increase

Throttle Control

The EB2510/EB3410 is equipped with a multi-function throttle control. The “Cruise” function allows the operator to use a thumb controlled lever for constant speed use without using the throttle trigger. This is useful for limiting the fatigue caused from holding the throttle for extended periods of time.

On the opposite side, a two position “Limiter” control allows full engine speed when set for “Turbo” or limits the throttle to a pre-set engine speed when set to low noise (dB) setting.

Cruise Function

Using the right thumb, push the throttle lock lever down until the desired min-1 (rpm) setting is reached. See Figure 10.

Using The Blower

Operating Tips

In the hands of an experienced operator, the EB2510/EB3410 can efﬁciently move a wide variety of debris ranging from grass clippings to gravel. As a general rule, operate your blower at the lowest throttle setting required to get the job done:

n Use low throttle settings when clearing

lightweight materials from around lawns or shrubbery.

n Use medium to higher throttle settings

to move grass or leaves from parking lots or walkways.

n Use full throttle when moving heavy

loads such as dirt or snow.

IMPORTANT!

Blower noise increases at higher throttle settings! Always use the lowest throttle setting required to get the job done!

Maintenance

IMPORTANT!

Maintenance, replacement or repair of emission control devices and systems may be performed by any repair estab-

lishment or individual, However, warranty

repairs must be performed by a dealer or service center authorized by Shindaiwa Corporation. The use of parts that are not equiv-alent in performance 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.

Daily Maintenance

WARNING!

To reduce re hazard, keep the engine and mufer free of dirt, debris, and

leaves.

WARNING!

Before performing any maintenance, 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.

CAUTION!

The engine is cooled by air drawn into the air intake cover on the blower housing. The blower fan then pushes the cooling air through an opening in the fan housing, forcing it past the

cylinder cooling ns. Failure to keep

the cooling system and its passages clear of debris will likely result in engine overheating, a major cause of serious engine problems that can lead to failure.

WARNING!

Non-standard parts may not operate

properly with your unit and may cause damage and lead to personal injury.

NOTE:

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

Prior to each workday, perform the following:

n Remove all dirt and debris from blower

exterior and the engine. Check the cooling ﬁns and air cleaner for clogging and clean as necessary.

n Inspect the engine, tank, and hoses for

possible fuel leaks, and repair as necessary.

n Inspect the entire blower for loose, dam-

aged, or missing components, and repair as necessary.

n Carefully remove any accumulations

of dirt or debris from the mufﬂer and fuel tank. Dirt build-up in these areas can lead to engine overheating, ﬁre or premature wear.

Every 10 Hours

(more frequently in dusty conditions)

1. Remove the air cleaner cover by loosening the thumb screw and lifting up. See Figure 13A.

2. Remove and inspect the pre-ﬁlter. If the pre-ﬁlter is torn or otherwise damaged, replace it with a new one. See Figure 13B.

3. Clean the pre-ﬁlter with soap and water. Let dry before reinstalling.

4. Inspect the air cleaner element. If the element is damaged or distorted, replace it with a new one. See Figure 13B.

n INSPECTION Inspect the entire blower

and tubes for damage, including loose or missing components, and repair as necessary.

n SPARK PLUG Replace the spark plug

with a NGK CMR5H (or equivalent), gapped to 0.6mm (0.024 in.).

n FUEL FILTER Use a hooked wire to

extract the fuel ﬁlter from inside the fuel tank. See Figure 15.

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.

139/150-Hour Maintenance

Maintenance after rst 139-hours, then every 150-hours thereafter.

n Combustion chamber should be decar-

bonized, and the valve clearance should be adjusted. It is highly recommended that this is done by a Shindaiwa-trained service technician.

n Replace the spark plug annually: Use

only NGK CMR5H or equivalent resistor type spark plug of the correct heat range. Set spark plug electrode gap to 0.6mm (0.024 in.).

NOTE:

The NGK CMR5H also meets the requirements for electro magnetic compliance (EMC).

n Inspect the ﬁlter element for signs of

contamination from debris. A contaminated fuel ﬁlter should be replaced with a new Shindaiwa replacement element. Before reinstalling the ﬁlter, inspect the condition of the fuel line. If you note damage or deterioration, the blower should be removed from service until it can be inspected by a Shindaiwa-trained service technician.

n COOLING SYSTEM Use a wood or

plastic scraper and a soft brush to remove dirt and debris from the cylinder ﬁns and crankcase.

Valve Adjustment

Remove cylinder cover, rocker arm cover,

and set piston at TDC-compression.
