MAINTENANCE
1. To check the bump bar trip force, a tension
gauge or similar tool must be used.
2. Make sure the engine is at full RPM and the
machine has been pre-run to warm up the
hydraulic oil.
3. With a tension gauge or similar tool trip the
bump bar at fi ve separate spots as shown in
Figure 1. Testing of the trip force needs to be
done in a swift, continuous motion straight into
the bump bar.
4. Record the trip force at each individual spot and
calculate the average.
5. The bump bar trip force from the factory is
approximately 30 lbs. (13.6 kg). This can vary
depending on items such as the width of the
infeed tray, hydraulic oil fl ow, if the parts are
worn, if the pivot points need lubrication, etc.
The trip force of the bump bar should not exceed
50 lbs. (22.7 kg). If the trip force does exceed
50 lbs. (22.7 kg) check for binding of any parts,
worn hydraulic valve, or any obstructions. If the
required force can not be obtained contact your
local dealer or Bandit Industries Inc.
1. The reveal distance is the distance that the
bump bar protrudes from the infeed tray while
in the feed position.
2. Check the reveal distance on each end of the
bump bar. Measure and make sure it protrudes
approximately 1 1/4” (31.8 mm) from the infeed
tray (see Figure 2).

The hydraulic bump bar valve may trip at diff erent
forces, depending on the temperature of the
hydraulic fl uid.
