Lubrication
The four drum bearings in the bearing blocks
need to be lubricated every 20 hours of
operation. However, all other bearings used on
this machine are shielded and permanently
lubricated. Simply leave them alone until they
need to be replaced. DO NOT lubricate them, as
this will only attract dust and cause possible
premature bearing failure.
DO NOT apply grease on any exposed areas on
the sander like the feed conveyor chain,
sprockets, and the table lead screws. If you do,
sanding dust and abrasives will collect on these
parts and create a gummy mixture that can
hamper proper movement of components and
increase wear. Use a light machine oil and a dry
graphite lubricant.
To lubricate the sander, do these steps:
1. Unplug the double drum sander.
2. Clean the sander as outlined in General
Cleaning procedures on Page 34.
3. Open the dust hood to gain access to the four
drum-bearing-housing grease zerks. See
Figure 57.
4. Remove the grease zerk cap from the bearing
block housing, wipe all contamination off of
the zerk, and squirt two pumps of high-
quality lithium-base grease into the bearing.
DO NOT over-grease the bearing.
5. Coat the exposed areas of the table lead
screws with dry powdered graphite.
6. Coat the feed conveyor chain and sprockets
with a light machine oil, and use a rag to
wipe-off the residual oil. See Figure 52.
7. Put three drops of the machine oil in the
handwheel bushing oil port and a couple of
dabs of lithium-base grease on the
handwheel gears. See Figure 53.
8. Wipe off any loose grease and replace the
dust cap.
9. Repeat Steps 1 through 6 for the three
remaining drum bearings.
10.Close the dust hood and close the latches.

MAINTENANCE
If any part of the sander becomes difficult to
operate, it is most likely caused by an
accumulation of sawdust. Immediately
troubleshoot the area and remove any
sawdust. Or contact
