1. Safety instructions

In the interest of promoting the safest and most efficient use of the Models CS 33EDT and CS 33EDTP

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

salespersons carefully ensure that the buyer seriously recognizes the importance of the instruction manual,

and fully understands the meaning of precautions listed on the caution plate and name plate attached to

each tool.

Have the customers refer to the instruction manual for how to properly handle, maintain, inspect and store

the product, with emphasis placed on periodic inspection.

Also advise customers to utilize our replenishment and repair systems for spare parts.

A. Instruction manual

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 instruction manual 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 instruction manual in order to give pertinent advice to the customer.

B. Caution plate

The name plate and caution plates attached to the product describe cautions requiring special attention to

ensure safe use of the product.

2. Thorough instruction to the customers

A. Thorough instructions on start/stop methods

Thoroughly instruct the customers on how to start and stop the product.

Regarding startup, emphasize the difference between “when the engine is cool” and “when the engine

is warm,” and focus on cautions regarding chain blade rotation with the choke fully open after initial

combustion at choke startup and at startup with the throttle open halfway.

B. Fuel used

This product is equipped with a two-cycle gasoline engine; instruct the customers how to use the

fuel mixed adequately at a ratio of [25 to 50] to one for gasoline and two-cycle dedicated oil.

Using plastic bottles such as polyethylene and PET bottles to store fuel will lead to trouble due to

dissolved plastics components. Instruct customers to only use bottles specifically designed to store

fuel.

The fuel deteriorates and changes in quality when stored for a long time. Improper storage

conditions such as a loose plug in summer may cause deterioration even in one day. Therefore,

instruct the customers not to store prepared fuel, but only prepare fuel on an as-needed basis.

C. Chain oil

Instruct the customers to use Hitachi chain saw oil (1 liter) sold separately or commercially available

SAE20 or SAE30 engine oil.

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

D. Adjusting saw chain tension

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

under extremely low tension. In particular, new saw chain tend to quickly elongate; therefore, advise

the customers to frequently adjust saw chain tension.

E. Storage

When the chain saw is not to be used for a prolonged period, instruct the customers to empty the fuel

tank and run the chain saw in idling mode until it stops in order to empty the carburetor.

The carburetor must be emptied since the gasoline component of mixed fuel left in the carburetor will

vaporize over an extended period of time, thereby inhibiting engine startup next season due to the fuel

line being clogged by a film of two-cycle dedicated oil.

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

(TROUBLESHOOTING GUIDE) as the context below follows it.

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.

When performing 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

assembly diagram for the Model CS 33EDT; <Bold> numbers correspond to those in the Parts List and

exploded assembly diagram for the Model CS 33EDTP.

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

1. How to check for sparks generated by the spark plug

CAUTION:

• Be careful not to touch the metallic portion of the spark plug when pulling the starter handle;

otherwise, you run the risk of electric shock. Wear gloves to avoid electric shock.

• Carefully wipe off any fuel around the plug to avoid a

sudden breakout of fire.

(a) Remove Spark Plug BPMR7A [94]<94> from the

Cylinder [93]<93>.

Use a wire brush to clean off carbon accumulated on

the Spark Plug BPMR7A [94]<94> electrodes, as

needed. Adjust the gap between the electrodes if

necessary. Use a cloth to wipe off any fuel on the

electrodes. Remove the fuel left in the Crank Case

[77]<77> according to the procedure below.

(1) With Spark Plug BPMR7A [94]<94> removed from

the Cylinder [93]<93>,

(2) Open the Choke Lever [49]<49> (with the Stop

Switch [128]<128> in the stop position),

(3) Open the throttle (with the Throttle Lever

[131]<131> pulled), and

(4) Pull the starter handle several times.

(b) Insert Spark Plug BPMR7A [94]<94> into the spark

plug cap, and then place the electrodes in contact with

the metallic portion of the engine. Under these

conditions, set the Stop Switch [128]<128> to the

startup position and pull the starter handle.

2. Adjusting the gap formed between the magneto

rotor and ignition coil

(a) Remove the Tapping Screw (W/Flange) D4 x 20

(Black) [169]<168>, and then remove the Recoil Starter

[168]<167>.

(b) Loosen the Hex. Socket Hd. Bolt (W/Washers) M4 x 18

[103]<103> so that the Ignition Coil [95]<95> is

temporarily tightened.

Magneto Rotor [86]<86> and the Ignition Coil [95]<95>

The following diagram shows the wiring.

(a) Insert the high voltage cord of the Ignition Coil [95]<95> through the Spark Plug Cap [101]<101> with a

small amount of oil applied to its tip. Then penetrate through the core wire of the high voltage cord with

the metal fitting of Plug Cap (A) [99]. Pull back the high voltage cord, and hold the metal fitting of Plug

Cap (A) [99]<99> within the Spark Plug Cap [101]<101>.

(b) Connect Cord (A) [100]<100> to the connector of the Ignition Coil [95]<95> and Stop Switch

[128]<128>.

Ignition Coil [95]<95> by using Hex. Socket Hd. Bolt (W/Washers) M4 x 18 [103]<103>.

4. Adjusting the carburetor

(a) Use the screw to adjust the carburetor.

• Idle adjust screw

Use the screw for adjusting engine speed during idling.

Turning the screw clockwise increases engine speed;

turning it counterclockwise decreases engine speed.

(b) Standard setting of the carburetor

2,800 to 3,200 min

(Confirm that the saw chain does not rotate.)

• Idling adjustment

(i) By using the Idle Adjust Screw [41]<41>, set the

revolutions so that the saw chain does not start

5. Cleaning the chain oil filler ports

(a) Remove the chain bar and remove any sawdust

clogging the filler ports.

(b) Remove sawdust from the groove on the chain bar

along which the saw chain travels, and from the chain

oil filler holes.

(a) With the Cylinder [93]<93>, Piston (M) [80]<80>, and Piston Ring [81]<81> removed, remove any

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

assembly.

(b) When assembling the Crank Case [77]<77>, be sure to apply liquid gasket (Three-Bond 1207C).
