Tightening the saw chain

-Slightly lift the end of the guide bar and turn the chain adjusting screw (I/6) to the right (clockwise) until the chain rests against the bottom side of the guide bar.

-While still holding up the tip of the guide bar, tighten the retaining nuts (H/3) with the universal wrench.

-The tension of the chain is correct if the chain rests against the bottom side of the guide bar and can still be easily turned by hand. While doing so the chain brake must be released.

-Every new chain has to be broken in for about 2 to 3 minutes. Ample chain lubrication is essential during this period. After breaking in, check chain tension and adjust, if necessary.

-When checking the chain tension the engine must be switched off.

NOTE: Check the chain tension frequently - chains tend to get longer during use! If this is not done, there is a risk of the chain jumping off the bar. It is recommended to use 2-3 chains alternatively.

In order to guarantee uniform wear of the guide bar the bar should be turned over whenever replacing the chain.

The MAKITA models comes with an inertia chain brake as standard equipment. If kickback occurs due to contact of the guide-bar tip with wood (see SAFETY PRECAUTIONS), the chain brake will stop the chain through inertia if the kickback is sufficiently strong. 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 emergency.

Engaging the chain brake (braking)

If the kickback is strong enough the sudden acceleration of the guide bar combined with the inertia of the hand guard (L/3) will automatically actuate the chain brake.

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

Releasing the chain brake

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