Thank you for having the manual I needed for an older model Aiwa stero I had found on Ebay --- I wanted the Aiwa because I had tapes and cd's but I did not have a manual as to how to operate the system... I found what I needed and it has enabled me to set the system up for my enjoyment.
I wished detailed information of the JBL S310 and here I found it! Very happy with the service from this site!

SAFETY INSTRUCTIONS
Adjusting the cutting height
Shut down the engine before changing the cutting height. Set the cutting height using the cutting height control on the right-hand side of the lawn mower. On lawn mowers with the type designation M48 Pro, proceed as follows: � To raise the cutting height move the lever to the left and then forward
�
To lower the cutting height move the lever to the left and then backward
On lawn mowers with the type designation M53 S Pro, proceed as follows: � To lower the cutting height move the lever to the left and then forward
�
To raise the cutting height move the lever to the left and then backward
Do not set the cutting height too low as there is a risk that the cutters might hit slopes with unevenness.
