This is one of four manuals I have downloaded recently.
Purchase was very straight forward and the authorising email arrived in about 4 hours.
The quality of the scan is good. Print is clear and square to the page edges.
Exactly as advertized. High quality digital copy of the Nak 610 user manual. Easy download and access. Highly recommended.

GENERAL SAFETY PRECAUTIONS
â¢ The chain brake (A) can either be activated manually (by your left hand) or automatically by the inertia release mechanism. The brake is applied when the front hand guard (B) is pushed forwards. â¢ To release the chain brake pull the front hand guard backwards, towards the front handle.
â¢ â¢ This movement activates a spring-loaded mechanism that tightens the brake band (C) around the engine drive system (D) (clutch drum).
Kickback can be very sudden and violent. Most kickbacks are minor and do not always activate the chain brake. If this happens you should hold the chain saw ï¬rmly and not let go.
â¢ â¢ The front hand guard is not designed solely to activate the chain brake. Another important feature is that it reduces the risk of the chain hitting your left hand if you lose grip of the front handle.
The way the chain brake is activated, either manually or automatically by the inertia release mechanism, depends on the force of the kickback and the position of the chain saw in relation to the object that the kickback zone of the bar strikes. If you get a violent kickback while the kickback zone of the bar is farthest away from you the chain brake is designed to be activated by the inertia in the kickback direction.
The chain brake must be engaged when the chain saw is started to prevent the saw chain from rotating.
If the kickback is less violent or the kickback zone of the bar is closer to you the chain brake will be activated manually by the movement of your left hand. â¢ Use the chain brake as a âparking brakeâ when starting and when moving over short distances, to reduce the risk of moving chain accidentally hitting your leg or anyone or anything close by.
