Note:
Ensure that the engine is at a normal
operating temperature before you adjust the
throttle cable.
2. Start the engine and use the throttle control to
decrease the engine speed to low idle.
3. Observe the low-idle engine speed on your
tachometer.
The ideal range for low idle is 1,800 to 2,000
rpm.
4. Loosen the screw on the cable-conduit clamp
(Figure 35).

5. Move the cable conduit until you observe 1,900
rpm on the tachometer.
6. Tighten the screw on the cable-conduit clamp.
Adjusting the High-Idle Engine
Speed
Note:
Use a tachometer to observe the engine
speed.
1. Park the machine on a level surface and engage
the parking brake.
Note:
Ensure that the engine is at a normal
operating temperature before you adjust the
throttle cable.
2. Start the engine and use the throttle control to
increase the engine speed to high idle.
3. Observe the high-idle engine speed on your
tachometer.

The ideal range for high idle (for use in
non-CE-compliant countries) is 3,350 to 3,550
rpm. If the tachometer shows a speed below
3,350 or above 3,550 rpm, perform steps
through 6
rpm is attained.
If you use the machine in a country that complies
to CE standards, adjust the high idle speed to
the following specifications:
•
Flex 1018 machines: 3,000 rpm
•
Flex 1021 machines: 3,150 rpm
4. Shut off the engine.
5. Adjust the throttle-control stop per the high-idle
reading on your tachometer.
•
To increase the high-idle-speed threshold,
move the throttle-control stop up.
•
To decrease the high-idle-speed threshold,
move the throttle-control stop down.

6. Start the engine and observe the new high-idle
reading.
If the tachometer shows the appropriate
speed as detailed in step 3, the adjustment is
completed.
