MQ SP-3035 CONCRETE SAW
Starting and Stopping the Engine
WARNING
Do not leave the saw unattended while the engine is running.
Do not start, park, or leave the saw unattended on a slope.
CAUTION
If the saw has an optional water pump, do not run the saw dry
with the water pump switch ON — otherwise the pump impellers
will be damaged.
In normal operation, do not stop the engine abruptly when hot!
Reduce the throttle to idle and allow the engine to run one or two
minutes before turning the ignition switch off.
1. Check Oil levels in engine and hydraulic system
2. If water pump option is installed, start water supply to blade.
3. Move the speed control joystick to NEUTRAL position.
4. Set the throttle to ½ open
5. Turn on/off switch to “START” position and at the same time pull out choke cable only
sufficient to start the engine. Release choke cable after engine starts. Re-choke if engine tends
to stall. When engine starts, release switch to “RUN” position. Allow engine to warm up
before applying load.
6. Ensure that water lines are attached and water is flowing to the saw.
7. Set the throttle to the recommended engine RPM to match the recommended blade speed of
the attached blade.
8. Lower the blade to the cut depth.
9. Move the joystick FORWARD to advance the cut.
10. When finished cutting, allow the engine to cool down by running at 1000 to 1200 RPM for 3
to 5 minutes depending on how hot the engine has been. This will reduce the chance of
engine damage or vapor lock.
WARNING
Make sure the operator knows how to turn the engine off in case of an
emergency.
Do not go near rotating parts (blade, belts, pulleys, or wheels) while
the saw is running.
To stop the engine, turn the “ON-OFF” switch to the “OFF” position.
