SP1G CONCRETE SAW • OPERATION MANUAL — REV. #3 (09/07/17) — PAGE 27
11. When blade has reached full cutting depth, slowly walk
behind the saw at a rate that will allow the engine to
operate without losing optimum RPM.
12. When the end of the cut has been reached, raise the
blade out of the cut by pulling back on the handlebars
(using a downward pressure) until the raise/lower rod
drops into its slot with the blade in the raised position.
13. If cutting is complete, shut the saw down using the
following shutdown procedure.
STOPPING THE ENGINE
Stopping the engine under normal conditions:
1. Place the engine throttle lever (Figure 20) in the slow
position, and listen for the engine speed to decrease.
Allow engine to run for 2 or 3 minutes for proper
cooldown.
2. Turn the engine shutdown switch (Figure 16) to the
OFF position. Shutting the engine off using this switch
confirms that is functioning properly.
3. Turn the engine ON/OFF switch (Figure 17) to the
OFF position.
4. Place the fuel valve lever (Figure 22) to the OFF
position.
Figure 22. Fuel Valve Lever (OFF)
CAUTION
DO NOT
try to cut faster than the blade will allow.
Cutting too fast will cause the blade to rise up out of
the cut. Improper cutting rate can decrease the life of
the engine and blades.

RESTARTING AFTER INTERVENTION
If cutting is interrupted where the engine stops or is
turned off while the blade is still in the cut:
1. Turn engine shutdown switch (next to the handle lock)
to the OFF position.
2. Raise the blade out of the cut.
3. Restart the engine as described in the Startup section.
If cutting is interrupted where the blade is stuck in
the cut:
1. Turn engine shutdown switch (next to the handle lock)
to the OFF position.
2. Remove the blade guard.
3. Remove blade mounting bolt and outer flange.
4. Maneuver the saw away from the stuck blade.
5. A parallel cut made next to the blade may be necessary
to free it.
6. Once the blade is freed inspect the blade for damage.
Discard if damaged.
7. Ensure an undamaged, useable blade is installed on
the saw before cutting is resumed with the saw.
CAUTION
The only acceptable method for freeing a stuck blade
is to remove the saw from the stuck or pinched blade.
DO NOT
try to get the blade unstuck using the Raise/
Lower system or by lifting the saw by the lifting bale, etc.
