the roller to maintain parallel orientation to the front
drum.
5. Replace the upper guard to its original position over
the drums.
NOTE: For proper operation of the machine, the dial
settings at both ends of the drum must be identical.
IMPORTANT: The chart at the right shows the proper
settings based upon sanding grits.
FIG. 13
OPERATION
The basic operating procedure for the Dual Drum Sander is as follows:
1. Establish the depth of wood removal and set table height.
2. Start drums.
3. Start feed belt and select proper feed rate.
4. Ensure dust collection system is running.
5. Feed stock through machine.
OPERATING TIPS
DETERMINING DEPTH OF
WOOD REMOVAL
Given the variables of grit abrasion, wood type, and
feed rate, determining proper depth of removal may
take some experimentation. For best results, use
scrap wood to practice sanding and to develop skill
and familiarity with the machine before doing finish
work. Also consider any cups and/or crowns in the
workpiece.
A good rule of thumb when sanding with grits finer than
80 is to lower the drum so it contacts the workpiece
but drum can still be rotated by hand. For grits coarser
than 80, lower the drum slightly more.
SANDING IMPERFECT STOCK
When sanding stock with a cup or crown, place the
crown up. This will stabilize the stock to help prevent
tipping or rocking during sanding. After the crown has
been removed and the top is flat, turn the stock over
and sand the opposite side. To avoid personal injury,
take special care when sanding stock that is twisted,
bowed, or otherwise varies in thickness from end to
end.
If possible, support such stock as it is being sanded
to keep it from slipping or tipping. Use an extra roller
stand, help from another person, or hand pressure on
the stock to minimize potentially hazardous situations.

13
OPERATING TIPS
STOCK FEEDING ANGLE
Some pieces, because of their dimensions, will need
to be fed into the machine at a 90-degree angle
(perpendicular to the drums). However, even a slight
offset angle of the stock will provide for more effective
stock removal. The optimum feeding angle is about
60-degrees. Angling the workpiece for stock removal
provides other advantages, such as less loading of
certain areas of the drums due to glue lines or mineral
streaks in the stock, more even wear of abrasive strips,
potentially faster feed rates, and lighter loads on the
motor. For the best final finish, however, the stock
should be fed with the grain on the final one or two
passes.
MULTIPLE-PIECE SANDING
When sanding multiple pieces simultaneously, make
sure to stagger (step) the pieces across the width of
the feed belt. Multiple pieces should also be of similar
thickness and this helps to ensure consistent contact
with the pressure rollers.
SANDING FACE FRAMES AND
RAISED PANEL DOORS
It is important to have the proper abrasive contact
when doing this type of sanding. If the machine is set
to take an excessive depth of cut, the result can be a
gouge or dip as the drum goes from sanding the rails
at full width to sanding just a few inches of width of the
stiles.
EDGE SANDING
When edge sanding, the sander will mimic the opposite
edge of the stock which is lying on the feed belt.
Because of this, it is important for the stock edge to
have been ripped at the proper angle to the face before
the sanding process. When edge sanding small stock,
clamp several pieces together to prevent them from
slipping on the feed belt.
The abrasive material you choose will have a
substantial effect on the performance of your sander.
Variations in paper type, weight, coating and durability
all contribute to achieving your desired finish.
As with any sanding operation, first begin sanding
with a coarser grit, depending on the roughness of
the stock or the amount of stock to be removed. Then
progressively work toward finer grits. This means if you
are using two different grits on your 31-481 Dual Drum
Sander, the coarser grit should always be placed on
the front drum.
The amount of stock to be removed is a major
consideration when initially choosing the grit grade.
Grits 36 and 60 are primarily designed for stock
removal; grits over 100 are primarily finishing grits
designed to remove the scratch pattern from the
previous grit used.
For best results, never skip more than one grit grade
when progressing through a sanding sequence.
For fine work, such as furniture, try not to skip any
grit grades during the sanding process. In general,
premium quality abrasives will produce a better finish
with a less noticeable scratch pattern.
CAUTION: Grits that are too fine can sometimes
burnish the wood and leave a glossy surface which will
not accept stains evenly. This will vary by type of wood.
Oak, for example, is susceptible to burnishing because
of its open pores.

RECOMMENDED MAINTENANCE PROCEDURES
ROUTINE INSPECTION
It is recommended that you periodically inspect your
DELTA®Dual Drum Sander as a precautionary action.
During this time, check all hardware such as bolts,
nuts and screws to ensure they are properly tightened.
Also verify that the sanding belts and drive belts are
mounted properly and have not become loose or torn.
Also take this opportunity to inspect for dust and/or
wood particles that may have accumulated on or in the
machine.
LUBRICATION
The table height adjustment screw shafts, located at
either end of the machine must be well lubricated with
grease at all times. In order to access, inspect and
lubricate the screw shafts, it is necessary to remove
the two side guards located on either end of the
machine.
To remove the side guards:
1. Remove the elevation cursor by unscrewing the
retaining screw.
2. Remove the eight Phillips head bolts and washers
securing the left and right side guards to the
machine and remove the guards. See Fig. 14.
3. Re-attach side guards and elevation cursor.
CLEANING THE SANDING BELTS
Regularly clean the sanding belts on the drums with
commercially available cleaning sticks, following the
manufacturer’s directions. When cleaning, also brush
the stick crumbs from the sanding drum while it is still
rotating.
