Since diamond blades cut best at specific rim-speeds, blades of different diameters must be turned at different blade shaft rpm’s.
The PA2013HSP will run either a 14 or 18” blade and the PA2020HSP 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.
Operating saw blades at rotational speeds greater than those recommended by the manufacturer can
cause blade damage and possibly subsequent personal injury.
Never exceed 3600 rpm blade shaft speed.
* The PA2013HSP 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!
blade speed and throttle setting
Warning
blade diameter set engine rpm to
14” full throttle (3500)
16” 3200-full throttle
18” 2850-3300
20” 2550-3000
The PA20 Series engine shaft to blade shaft ratio is 1:.895.
Raise the blade out of the cut by cranking the depth control wheel counter-clockwise. Raise the blade high enough out of the cut to
clear the pavement and allow maneuvering of the saw.
Move the engine throttle to the slow position then turn the kill switch off.
Turn off the water valve.
finishing a cut
cutting with the blade on the left side
Left side cutting can be easily accomplished by moving the blade guard to the left hand side of the saw belt guard using the following
steps:
1. Turn kill switch to off position.
2. Disconnect water hose from blade guard.
3. Remove shaft guard, from the left side of the saw frame and set aside.
4. Remove blade guard from the right side of the saw frame and reassemble on the left side of the saw belt guard.
5. Reassemble shaft guard on the right side of the saw frame.
6. Connect water hose to blade guard.
When attaching a blade to the left blade shaft, use the outside flange from the right side and the left side nut.
Do not operate saw with any guards removed. Turn kill switch to off position to avoid accidental starts when removing guards.
