Grease Fittings
Your shredder-chipper was greased at the Factory. The operator needs to lubricate the Chipper Side and Drive Side Bearings
periodically.
Tools and Supplies Needed:
•
Flexible hose grease gun
•
Grease
•
Clean cloth
•
5/32" Allen Wrench
•
Loctite
®
243 (if set screws are loose)
1. Wipe all dirt, etc., from the Grease Fittings on both Bearings with a clean cloth
(
Figure 9 ).
2. Apply no more than three pumps of quality general-purpose grease with a hand-
pumped grease gun to each Grease Fitting, one on the Chipper Side Bearing, and
one on the Drive Side Bearing (not shown). To access the Drive Side Bearing, you
will have to remove the Belt Guard (see below).
3. After greasing, check the Side Bearing Collar Set Screws ( Figure 11 ) for tightness
with a 5/32" Allen Wrench. There are two Set Screws per Bearing. If they are
loose, reset them with Loctite
®
243, obtainable at most hardware stores.
Tensioning, Replacing, and Aligning the Drive Belt
Use only a factory Belt on your machine. The Belt has been thoroughly tested and
proven for many hours of use.
CHECKING AND SETTING BELT TENSION
Tools and Supplies Needed:
•
Two 1/2" Wrenches
•
Straight Edge
1. Remove the Belt Guard by removing the two Locknuts and four Washers
with a 1/2" Wrench (
Figure 10) .
NOTE: One Washer is located under the Belt Guard Bracket and one on top of
the Bracket. Make sure you install the Washers in these same positions.
2. Place a straight edge onto the full length of the Belt ( Figure 11).
3. Push on the Belt with about three pounds of pressure. The Belt should
move approximately 3/8". If the distance is close to 3/8" no tension
adjustment is needed. If it is not close to 3/8" adjust per the following
directions.
4. Remove the Nut and Baffle Rod and set the Baffle Plate aside for better
access under the Engine (
Figure 10) .
