2-15. OPERATION OF RESCUE SAW (Continued)
(3)
Check controls.
(a)
Check that when you release the
throttle control (7, figure 2-7) en-
gine rpm drops and returns to idle
"by itself". Check that the wheel
does not move when the engine is
idling.
(b)
Check that the stop control (3, fig-
ure 2-7) does stop the engine.
d.
Operating.
The following techniques are general in
nature. Check instructions for each type
of wheel for individual cutting character-
istics. (Diamond blades, for example,
need less feed pressure than abrasive
wheels.)
(1)
Support work piece so that you know
what to expect while cutting so that it will
not bind.
(2)
Always cut at wide open throttle.
Absolutely never cut with the side of the
wheel; it almost certainly will be dam-
aged, break, and is likely to cause se-
vere injury. Use cutting edge only.
(3)
Start cut gently, do not bump or jam
wheel.
(4)
Use high wheel speed.
(5)
Move wheel slowly back and forth.
(6)
Use small portion of wheel's cutting
edge.
(7)
Use only the cutting edge of the wheel
for cutting.
