5.1.3
Basic setting without limiter cap
.
Starting from the tight position of the adjusting
screws:
Open
H = 2
turns
Open
L = 3 1/2
turns
Set the specified speeds within the tolerance range
of +/– 200 rpm.
1. Set speed to 3,300 rpm with idle speed
adjusting screw (LA).
2. Turn the low-speed adjusting screw (L)
clockwise or anticlockwise to set the highest
speed.
If this speed is greater than 3,700 rpm, stop and
start again with step 1.
3. Set the speed to 3,300 rpm again with idle
speed adjusting screw (LA).
4. Set the speed to 2,500 rpm with low-speed
adjusting screw (L).
5. Set the maximum speed with the high-speed
adjusting screw (H):
BR 500: 5,500 rpm
BR 550: 6,100 rpm
BR 600: 7,200 rpm
If you make the setting too lean it will increase the
risk of engine damage through lack of lubrication
and overheating.
