Safety chain brake

A

The models DCS 340/DCS 341/DCS 400 and DCS 401 comes with an inertia chain brake as standard equipment. The chain brake will automatically stop the chain if the kickback is sufficiently strong, which is caused by the tip contacting wood while the saw is running (see "SAFETY PRECAUTIONS", page 9). The chain will stop within a fraction of a second.

The chain brake is installed to block the saw chain before starting it and to stop it immediately in case of an emer- gency.

Engaging the chain brake (braking)

In case of kickback the chain brake is engaged automatically by inertial motion of the hand guard ((B/3).

To engage the chain brake manually, simply push the hand guard (B/3) forward (towards the tip of the saw) with your left hand (arrow 1).

Releasing the chain brake

Pull the hand guard (B/3) towards you (arrow 2) until you feel it catch. The brake is now released.

Fuel mixture

The engine of the chain saw is a high-efficiency two-stroke engine. It runs on a mixture of gasoline and two-stroke engine oil. The engine is designed for unleaded regular gasoline with a min. octane value of 91 ROZ (research octane number). In case no such fuel is available, you can use fuel with a higher octane value. This will not affect the engine.

In order to obtain an optimum engine output and to protect your health and the environment use unleaded fuel only. Gasoline which contens alcohol should not used in MAKITA products.

For lubricating the engine use a two-stroke engine oil (quality grade: TC-3), which is added to the fuel. The engine has been designed for use of MAKITA high-performance two-stroke engine oil and a mixture ratio of only 50:1 to protect the environment. In addition, a long service life and reliable oper- ation with a minimum emission of exhaust gases are ensured. MAKITA high-performance two-stroke engine oil is available in the following sizes to suit your individual requirements:

1 l	order number	980 008 607
100 ml	order number	980 008 606

In case MAKITA high-performance two-stroke engine oil is not available, it is urgently recommended to use a mixture ratio of 40:1, as otherwise optimum operation of the engine cannot be guaranteed.

The correct mixture ratio:

50:1 when using MAKITA high-performance two-stroke en- gine oil, i. e. mix 50 parts gasoline with 1 part oil.

40:1 when using other two-stroke engine oils, i. e. mix 40 parts gasoline with 1 part oil.

Handling and storage

Utmost care is required when handling with fuel. Fuel can contain substances which have a behavior similar to that of solvents. Fill the tank only outside or ventilated rooms. Do not inhale vapors, avoid any fuel contact with your skin. Fuel cannot be stored. Purchase only the quantity needed for a period of 4 weeks. Use licensed fuel containers only.

For preparing the fuel-oil mixture first mix the entire oil quantity with half of the fuel required, then add the remaining fuel. Thoroughly shake the mixture before pouring it into the chain saw tank.

NOTE:

It is not wise to add more engine oil than specified to ensure safe operation. This will only result in a higher production of combus-tion residues which will pollute the environment and clog the exhaust channel in the cylinder as well as the muffler. In addition, fuel consumption will rise and performance will decrease.

Chain oil

Use an oil with adhesive additive for lubricating the chain and guide bar. The adhesive additive prevents the oil from being flung off the chain too quickly.
