valve is turned o.
4. Place a pan under the drain plug.
5. Remove the drain plug and allow oil to
drain for 10 minutes.
6. Install the engine drain plug and tighten.
7. Dispose of the oil in an approved contain-
er.
8. Add the specied type and amount of mo-
tor oil. Refer to Section 5.1.1 or the engine
manual.

5.2.2 ENGINE SPEED SETTING
Every engine is shipped from the engine fac-
tory without gas or oil because of re hazards
during shipping. They are all set with a high
idle of 3500 RPM. Since no uids are added at
the Mixer factory, the RPM is not reset. When
the Mixer is delivered, the uids must be
added and the RPM reset. To reset the RPM,
follow this procedure:
1. Read the engine manual supplied with
the machine.
2. Add fuel and the specied motor oil to
the crankcase and oil to the gearbox.
3. Start the engine and run at wide open
throttle.
4. Use a screwdriver to reset the high idle
stop screw.
5. Count the mixing element revolutions to
determine engine RPM. Set the engine
speed to give 30-35 RPM for the paddles
and 40-45 RPM for the spiral when mixing.
6. Load the drum and count the mixing ele-
ment rotational speed again.
7. Reset if the speed changes as required.
