MK-20 SERIES
BLADE SPEED AND THROTTLE SETTING
Since diamond blades cut best at specific rim-speeds, blades of different diameters
must be turned at different blade shaft rpm's.
The MK-2013/14 will run either a 16" or 18" blade and the MK-2020/24/22 HSP will run
a 16" through 20" blade.
Safe, efficient, economical cutting performance will occur at the engine rpm (as read on
the tachometer) stipulated on the following chart.
The MK-20 Series engine shaft to blade shaft ratio is 1:895.
WARNING
Operating saw blades at rotational speeds greater than those recommended
by the manufacturer can cause blade damage and possibly subsequent per-
sonal injury.
Never exceed 3600 rpm blade shaft speed.
* The MK-20 Series, it is possible to cause overspeeding of the blade at throttle
settings above those stipulated on the above chart; DO NOT EXCEED THESE
ENGINE RPM SETTINGS!
