This GRUNDIG UV5A Owner Manual is not only an instruction manual but a total functional circuit description of the Multimeter and includes circuit diagram at the end pages. It is very helpful for repairing and calibrating the instrument. It is written in two languages English and German for international support. It was very easy to repair my unit with this document. Regards, Regis Pauly, Electrical Engineer.
The owner's manual was evetything I thought it would be. I was able to print it out using both sides of the paper in quick order, saving me a search online for a used one.
Was happy to find the complete owners manual... It's all in there, just like the original...

MAINTENANCE
Checking the inertia brake release
Throttle lock
Place the chain saw, with the engine switched off, on a stump or other stable surface. Release the front handle and let the saw fall by its own weight, rotating around the rear handle towards the stump.
�
Make sure the throttle control is locked at the idle setting when the throttle lock is released.
�
Press the throttle lock and make sure it returns to its original position when you release it.
When the bar hits the stump the brake should be applied.
�
Check that the throttle control and throttle lock move freely and that the return springs work properly.
Checking the brake trigger
Place the chain saw on �rm ground and start it. Make sure the chain does not touch the ground or any other object. See the instructions under the heading Start and stop. � Start the chain saw and apply full throttle. Release the throttle control and check that the chain stops and remains stationary. If the chain rotates when the throttle control is in the idle position you should check the carburettor idle adjustment.
Chain catcher
Grasp the chain saw �rmly, wrapping your �ngers and thumbs around the handles.
Check that the chain catcher is not damaged and is �rmly attached to the body of the chain saw.
Apply full throttle and activate the chain brake by tilting your left wrist forward onto the front hand guard. Do not let go of the front handle. The chain should stop immediately.
