Bandit INTIMIDATOR 15XP/1390 Operating & Parts Manual page 73

MODEL 15XP/1390
NOTICE
Knives should be replaced in sets. These sets are
determined by the amount of resharpening done to
the knives. It should be reinstalled with another knife
of comparable usage. It helps to keep the disc/drum
balanced, and it helps maintain chip quality.
NEVER allow these knives to wear or be sharpened
beyond absolute specified minimum distance from
the center line of bolt.
TROUBLE SHOOTING CHIPPER PROBLEMS
1. Chipper makes poor quality chips or does
not feed properly.
A. Knives have lost their edge. Sharpen or
replace knives. DO NOT operate the Bandit
with dull knives.
B. Knife anvil worn or needs adjustment. Rotate,
repair or replace (see Figure 1).
C. Feedwheel(s) are not operating correctly.
(SEE HYDRAULIC TROUBLE SHOOTING).
D. The throat/base opening is a high-wear area.
The feed plate anvil takes much of this wear
but other areas wear as well. Attention must
be paid to any areas where outer, noncutting
edges of chipper knife are exposed. These
areas must be built up with weld to maintain
the original integrity.
E. Knives are at the wrong angle. Knives must
be ground at a 30° to 30 1/2° angle.
F. Feedwheel teeth worn (REPLACE).
G. Material being chipped is very small, dry or
rotting. This type of material does not produce
good chip quality.
2. Chipper Knife Hits Anvil.
A. Check the anvil clearance at both sides of the
knife by using a feeler gauge, the clearance
should be approximately .120" (3.0 mm) from
the highest knife.
B. Check the chipper bearing bolts for tightness
(SEE TORQUE CHART).
FIGURE 1
If anvil is not too worn, the two
working edges can be ground or
machined to repair.
NOTE: Make sure the anvil clearance will still be
obtainable after grinding or machining.

Through various tests, Bandit has found that using
the Knife Saver will increase the life span of chipper
knives if used during the recommended times.
Each knife installed in every new machine at Bandit
has the Knife Saver used on it before leaving the
factory. The Knife Saver can be purchased from
your local Bandit dealer.
- Use the Knife Saver on brand new knives.
- Use the Knife Saver on freshly resharpened knives.
- Use the Knife Saver every day during the Daily
- Use the Knife Saver when the machine is shut

Properly.
A. Lugging engine on large material - keep
engine RPM up.
B. Knives are dull or worn to minimum size.
C. Obstruction in discharge chute. Patches
welded into the chute can cause obstruction
of chip flow. Anything causing an obstruction
will cause the chute to plug.
D. Chipping rotting material that has little
substance can also plug the discharge chute.
E. Worn fan blades.
A. Improper lubrication - purge bearings once a
day with EP-2 Lithium type grease.
B. Chipper drum operating at too high RPM's. DO
NOT exceed recommended RPM's.
C. Bearings worn out (REPLACE).
