As current 38/43 mL chain saws do not comply with exhaust gas regulations, we are selling these products on

credit in North America and according to small-quantity production regulatory limits in Europe. Therefore, we

cannot expand the sales of such products.

nd in line with the trend toward targeting general users instead o

semiprofessionals for chain saws of the 40 mL displacement class, other companies have been releasing new

products with lower prices. To compete with this situation, we are releasing these two new models.

1. Safety Instructions

In the interest of promoting the safest and most efficient use of the Models CS 40EA (S) and CS 40EA (PS)

Engine Chain Saws by all of our customers, it is very important when concluding a sale that the

salesperson carefully ensure that the buyer seriously recognizes the importance of the Handling

Instructions, and fully understands the meaning of precautions listed on the Caution Plate and Name Plate

attached to each tool.

A. Handling instructions

Although every effort is made in each step of design, manufacture, and inspection to provide protection

against safety hazards, the dangers inherent in the use of any chain saw cannot be completely eliminated.

Accordingly, the Handling Instructions lists specific precautions and suggestions on use of the chain saw to

enhance the safe and efficient use of the tool by the customer. Salespersons must be thoroughly familiar

with the Handling Instructions in order to give pertinent advice to the customer.

B. Caution plate

The Models CS 40EA (S) and CS 40EA (PS) are provided with a Warning Label (illustrated below) that lists

basic safety precautions on use. Carefully ensure that customers fully understand and follow these

precautions before using the tool.

[For Asia]

[For the USA]

[For Europe]

PRECAUTIONS ON SALES PROMOTION

-5-

[For Russia]

[For Australia]

C. Meaning of symbols

Read and understand the meaning of each symbol described in the Handling Instructions, and properly

instruct the users.

2. Thorough Instruction to the Customers

A. Starting and stopping procedures

Thoroughly instruct customers about the difference between the cold starting procedure and the hot

restarting procedure, and also the importance of starting with the throttle trigger positioned at the fast-idle

start position.

B. Fuel safety

An engine based on a two-cycle design powers the Models CS 40EA (S) and CS 40EA (PS). Instruct the

customers to use a mixture of gasoline and two-cycle oil at a ratio of 25 to 50:1 as fuel.

Instruct the customers to use a container intended for mixing gasoline and oil. The use of such resin

containers as poly tanks and PET bottles could cause failure by possibly melting into the mixture.

Fuel stored for a long time becomes degraded and deteriorated. Improper capping can also degrade fuel in

a single day, especially in summer. Instruct the customers not to store mixed fuel, but to only prepare the

required amount of mixture as needed.

C. Storage

Instruct customers to empty the fuel tank and perform idling until the engine stops, in order to burn up any

residual fuel in the carburetor before long term storage of the Models CS 40EA (S) and CS 40EA (PS). Should

any fuel remain in the carburetor, only the gasoline mixed in the fuel volatilizes during the storage period,

thereby clogging the fuel line with two-cycle oil. Consequently, the engine cannot be started the next time.

D. Chain oil

Instruct customers to use chain oil. Specially instruct them to use commercially available SAE20 or SAE30

engine oil.

Remind customers to always replenish the chain oil when replenishing the fuel.

E. Adjusting saw chain tension

Low tension of saw may damage the blades or guide bar, and even result in blades being detached under

extremely low tension. A new saw chain tends to quickly elongate; therefore, advise customers to

frequently adjust saw chain tension.

TROUBLESHOOTING GUIDE

-7-

This section describes repair, focusing on portions requiring frequent repair. Refer to TROUBLE

SHOOTING GUIDE in the previous section as the context for the following descriptions.

1. Precautions on Maintenance, Inspection and Repair

• The fuel used readily ignites; therefore, never bring the product near a flame.

• Use new gaskets at reassembly.

• Prior to disassembly for repair, remove the fuel and chain oil into separate containers, and allow the

engine to cool down.

• During repair, startup or running, use adequate care for portions posing the risk of burn injury or electric

shock, such as hot areas including the muffler, high voltage cord and spark plug.

• Before running the product with the chain bar and chain blades attached, make sure that there are no

other people nearby.

• Ensure proper ventilation when performing repair in a small room or other poorly ventilated space.

• After completing repair, always return the throttle lever to the idling position and set the stop switch to the

engine stop position.

[Bold] numbers in the descriptions below correspond to item numbers in the Parts List and exploded

Always stop the engine prior to disassembly or when replacing the saw chain.

1. Checking the spark of the Spark plug

CAUTION: • Be careful not to touch the metallic portion of the

Spark Plug [13] when pulling the starter handle;

otherwise, you run the risk of electric shock.

• Carefully wipe off any fuel around the plug to

avoid a sudden breakout of fire.

(1) Remove the Spark Plug [13] from the Cylinder Ass’y [63].

Use a wire brush to clean off carbon accumulated on the

Spark Plug [13] electrodes, as needed. Adjust the gap

between the electrodes if necessary. Use a cloth to wipe off

any fuel on the electrodes. Remove fuel left in the Crank

Case Set [69] according to the procedure below.

(a) With the Spark Plug [13] removed from the Cylinder Ass’y [63]:

(b) Open the Choke Button [92] (by pushing it) and set the

top Switch [93] to the s

top position.

(d) Pull the Starter Knob several times.

(2) Insert the Spark Plug [13] into the plug cap, and then place

the electrodes in contact with the metallic portion of the

engine. Under these conditions, set the Stop Switch [93] to

the startup position and pull the Starter Knob.

(3) When all the above are normal, the Spark Plug [13]

electrodes make a snapping sound to generate sparks.

2. Adjustment of air gap (clearance)

(1) Remove the Tapping Screw (W/Flange) D5 x 20 (Black) [39] and then the Recoil Starter [174].

(2) Loosen the two Hex. Socket Hd. Bolt (W/Flange) M4 x 18 [51] to the extent that the Ignition Coil [50] is

temporarily secured.

(3) Insert a clearance gauge between the magnetic steel portion around the perimeter of the Magneto Sub

Ass’y [80] and the Ignition Coil [50], and then adjust the position of the Ignition Coil [50] so that the

clearance becomes 0.3 mm to 0.4 mm.

(4) Under this condition, firmly tighten the Hex. Socket Hd. Bolt (W/Flange) M4 x 18 [51].

5. Cleaning the chain oil filler ports

(1) Remove the Chain Bar and remove any sawdust clogging the filler ports.

(2) Remove sawdust from the groove on the Chain Bar (along which the saw chain travels) and from the

chain oil filler holes.

(1) With the Cylinder Ass’y [63], Piston (M) [67] and Piston Ring [65] removed, remove carbon accumulated

on the cylinder exhaust port and piston, and use gasoline to thoroughly clean the disassembled

components. Apply two-cycle dedicated oil to the bearings and sliding sections for reassembly.

(2) Make sure that the Clutch [158] is left-threaded in the Crank Shaft [77].
