4.4.5 Throttle Cable Adjustment
1. With the engine OFF, lightly depress the accelerator
pedal (1) to the full-throttle position.
2. Block the accelerator pedal to the full throttle position,
check the throttle position on the fuel injector pump on
the engine. The throttle lever should be bottomed
against the limit-stop screw.
3. If there is an adjustment needed, return to the cab
and adjust the throttle cable (2) so the lever on the
fuel injector pump bottoms against the limit-stop just
before the throttle pedal bottoms against the limit-
stop (3) in the cab.
4. Remove the block holding the throttle before starting
machine.
4.4.6 High Idle Adjustment
Note: Engine coolant temperature must be between
10 and 38° C (50 and 100° F).
ANSI Machines
1. Start the machine and allow engine to low idle for
approximately 30 seconds.
2. Verify low idle (900 ± 50 rpm). Low idle is a factory
non-adjustable setting.
3. Bring engine to full throttle. If high idle rpm is not
2335 ± 75 rpm, readjust the throttle cable at the
throttle pedal in the cab.
CE Machines
1. Start the machine and allow engine to low idle for
approximately 30 seconds.
2. Verify low idle (900 ± 50 rpm). Low idle is a factory
non-adjustable setting.
3. Bring engine to full throttle. If high idle rpm is greater
than or equal to 2340 rpm, a thick throttle stop will
need to be installed. If high idle rpm is less than
2340 rpm, a thin throttle stop will need to be
installed.
4. Return engine to low idle and shut engine OFF.
5. Allow the engine to cool. Install proper throttle stop
(4) and verify high idle is correct.
6. Restart engine, bring engine to high idle. High idle
must be between 2005 and 2090 rpm.
Note: For the proper throttle stop, contact the local JLG
dealer.
