CHECK INTERLOCK SYSTEM
The safety interlock system's purpose is to prevent the
engine from cranking or starting unless the traction drive
lever is disengaged and the coring head is raised. It also
interrupts engine operation if a handle-mounted interlock
lever is not activated when the coring head is lowered.
To check the interlock system:
1.
Position the machine on a flat, open area. Start the
engine; refer to Starting and Stopping instructions.
2.
Check the clutch switch (Fig. 14) with a continuity
tester or ohm meter and replace it if damaged. The
switch must be closed when the gear shift lever is in
a gear. The switch must open when shifting between
Neutral, First, and Second gears.
3.
To adjust the switch, loosen the mounting screws and
reposition the switch as required.
4.
If the coring head is in the raised position and the
engine will not start, or continues to run when the
coring head is down and the interlock lever(s)
released, there is a defect in the interlock system, pro-
ceed to step 5.
5.
Check the coring head switch (Fig. 15) with a conti-
nuity tester or ohm meter and replace if damaged.
The switch plunger must be depressed when the cor-
ing head is in the raised position.
