Operation
If the saw should stall for any reason, raise the blade out of the cut before
restarting the engine!
When lowering the blade into a partially made cut, the blade must be
perfectly aligned within the cut before starting to saw again.
DO NOT
force the blade into the material by lowering the blade too fast.
5.10 Sawing a Straight Line
The following items should be considered for best economy and efficiency
in sawing:
With the water on, engine at the correct throttle setting, and
the blade lowered, push the saw forward referring to the pointer
alignment.
The saw has a natural tendency to pull towards the side on
which the blade is mounted. To assure straight line cutting, apply
pressure to the appropriate handle. If excessive pressure is required
back off on the forward speed of the saw. If excessive pressure is
still required to make the saw travel straight, the saw may need to
have the arbor shaft adjusted.
Avoid sudden corrective actions when the saw deviates from the
intended line of cutting. Sudden and severe corrections can cause
the blade to be damaged or broken.
If the saw stalls in the cut, raise the blade out of the cut and check
the blade shaft nut before restarting the engine.
Always raise the blade completely out of the cut before stopping the
engine or turning off the water supply.
When sawing joints, be careful not to let the blade cut into the forms.
The forward speed of the saw, during cutting, should be regulated by the
operator. Driving the saw too fast while cutting may cause the front wheels
to lift causing the blade to cut at uneven depths.
The three controlling factors of cutting economy are: a) Depth of cut,
b) Forward speed of the saw and c) Blade cutting ability.
Experimental adjustment of these items, with respect to the specific
concrete aggregate being cut will result in the best cutting economy.
As new blades wear, the cutting ability usually improves. It is best to start
at a slow forward speed with a new blade and work up to a desired cutting
speed gradually.
5.11 Finishing a Cut
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.
