ADJUSTMENTS
Warning: To avoid possible serious personal injury, user must unplug power cord
from power source before attempting to do any of the following adjustments.
SANDING DRUM ALIGNMENT
The following section will describe the verification and adjustment if needed of
the tightness of the elevation tension adjustment nylon hex. nuts and the sanding
drum to feed belt alignment.
Verification and adjustment of the tightness of the elevation tension
adjustment screws
1) The elevation tension adjustment nylon hex. nuts (A) Fig.13 set the
smoothness of the height adjustments. If these nylon hex. nuts are loose, the
drum will deflect during use. If the nylon hex. nuts are too tight, it will be very
difficult to set the desired height.
2) To verify and adjust the elevation tension adjustment nylon hex. nuts (A)
Fig.13, loosen or tighten each adjustment nylon hex. nut as required, turning
only a 1/4 turn at a time until the correct adjustment is obtained.
Verification and adjustment of the alignment of the sanding drum
When checking the alignment of the sanding drum in relation to the feed belt, the
goal is to obtain equal distances at point A and point B as shown in Fig.14. Place
two identical blocks of wood (A & B) Fig.14 under the drum on the feed table, one
at each end as shown. Lower the drum until the drum touches one or both of the
wood blocks. If point A and point B are not equal proceed as follows:
1) Loosen the 4 nylon hex. nuts (A) Fig.15.
2) If the Open Drum Sander is installed on the stand or bolted to a workbench,
loosen the mounting hardware (B) Fig.15 at the motor end of the machine.
3) If the drum is touching at point A but not point B.
- loosen hex. nuts (C), adjust hex. bolts (D) by turning them clockwise. Verify
adjustment, lower the drum until point A and point B are at equal distances,
retighten hex. nuts (C). Retighten 4 nylon hex. nuts (A) and mounting
hardware (B).
4) If the drum is touching at point B but not point A.
- loosen hex. nuts (E), adjust hex. bolts (F) by turning them clockwise. Verify
adjustment, lower the drum until point B and point A are at equal distances,
retighten hex. nuts (E). Retighten 4 nylon hex. nuts (A) and mounting
hardware (B).

ASSEMBLY & ADJUSTMENTS
ADJUSTMENTS
ADJUSTING FEED BELT (CONVEYOR)
Warning: To avoid possible serious personal injury, user must unplug power cord
from power source before attempting to do any of the following adjustments.
Due to feed belt stretching, it may be required to adjust the feed belt tracking/
tension.
1) The feed belt tracking/tension adjustment screw mechanisms are located on
the infeed side of the feed belt, one on each end of the feed belt.
2) To tighten the tension, turn the adjustment screw (A) Fig.16 clockwise while
holding the hex. nut (B) in place with an open end wrench. To loosen the feed
belt tension, turn the adjustment screw (A) Fig.16 counterclockwise while
holding the hex. nut in place with an open end wrench. It is important to make
identical adjustments to the tracking/tension adjustment screw mechanisms on
both sides of the feed belt.
3) If the feed belt is tracking towards the motor side, add tension to the
adjustment screw (A) Fig.16 on that side of the machine.
Note: Due to the width of the feed belt, tracking adjustments may not become
apparent right away. Increase the feed belt speed so the adjustment is easier to
see. Make small measured corrections of approximately 1/4 turn increments and
evaluate the results. Readjust as needed until feed belt is tracking properly.
SETTING UP AND USING THE DIGITAL DEPTH GAUGE
A digital depth gauge for sanding thickness is included as standard equipment
with this Open Drum Sander. A digital depth gauge offers the most precise
reading of sanded thickness and allows for accurate repeatability of a thickness.
This is ideal when making parts that must be an exact thickness or when
matching a thickness.
1) To set up and operate the digital depth gauge (A) Fig.17, first install the battery
(CR2032) in the battery compartment (B). Then press the ON/OFF button (C)
and then use the MM/IN button (D) to select between the standard metric
millimeter or inch settings.
2) With the sanding belt installed, lower the drum until it touches the feed belt.
Then press the Zero button (E) Fig.17 to calibrate the digital depth gauge to
absolute zero. The digital depth gauge is now set to read sanding thickness.
3) The ABS button (F) Fig.17 selects Absolute (ABS) mode. ABS mode is used
to read the actual thickness of the workpiece.
4) To turn off the digital depth gauge, press the ON/OFF button (C) Fig.17. It is
recommended to remove the battery when not in use.
ADJUSTING THE TENSION ROLLERS
Figure 16
Figure 17
Figure 18
The tension roller pressure is factory set and should be adequate. However, the pressure of each roller can be adjusted as needed.
1) To increase the front tension roller tension turn the tension adjusting screw (A) Fig.18 clockwise 1/4 turn at a time at both ends of the front
tension roller. To decrease tension turn the tension adjusting screw (A) counterclockwise 1/4 turn at a time.
2) To increase the rear tension roller tension turn the tension adjusting screw (B) Fig.18 clockwise 1/4 turn at a time at both ends of the rear
tension roller. To decrease tension turn the tension adjusting screw (B) counterclockwise 1/4 turn at a time.
OPERATION
OPERATION
SETTING DRUM HEIGHT/DEPTH OF CUT
Determining the depth of cut is the most important operating procedure decision.
It may take some experimentation to determine the proper depth of cut. Variables
to keep in mind are abrasive grit, type of wood, type of project, and conveyor feed
belt speed. We highly recommend practicing on a scrap of wood prior to sanding
a final project.
1) The height of the drum is raised or lowered by turning the drum height control
handwheel (A) Fig.19. To raise the drum, turn drum height control handwheel
clockwise. To lower drum, turn drum height control handwheel counter-
clockwise.
2) A 1/4 turn of the drum height control handwheel will raise or lower the drum
approximately 1/64”. One complete turn is 1/16”. Never attempt to remove
more than 1/64” of material in one pass
3) Depth setting can be measured using the digital depth gauge (B) Fig.19. See
setup and operation instructions on the previous page.
A good rule of thumb when sanding is to place the workpiece under the drum and
lower the sanding drum until the workpiece makes contact with the drum, but the
drum can still turned by hand.
DUST COLLECTION
When using this Open Drum Sander, dust collection is required for a safe work
environment and to extend abrasive life. Make sure this Open Drum Sander is
connected properly to a dust collector before operating. See Fig.12.
SETTING THE FEED BELT FEED RATE
After the depth of cut has been determined, selecting the proper feed belt feed
rate is essential. To achieve best finish a slow to moderate feed rate is
recommended. This allows for the most revolutions of the drum per inch of sanding.
Figure 19
Figure 20
Faster feed rates can be used as long as the machine is not over-stressed. When finish sanding with grits finer than 80, the best finish can
usually be obtained if you make another sanding pass without changing the thickness setting and sand again.
1) The feed belt (A) Fig.20 feed rate is controlled by the variable speed dial (B). Turn the dial clockwise to activate the feed belt, turn dial until
desired feed rate is obtained.
2) The feed rate range is 0 to 31 inches per minute. The dial nameplate indicates numbers which approximately translate as follows:
Setting 2 (7” per/min), Setting 4 (13” per/min), Setting 6 (19” per/min), Setting 8 (25” per/min) and Setting 10 (31” per/min).
STARTING SANDING DRUM
Warning: Make sure the workpiece is not in contact with the drum before turning on the drum motor. The drum and feed belt motors must be
running before attempting to feed a workpiece through the Open Drum Sander.
1) To start the Open Drum Sander, press the green start button (C) Fig.20. To stop the Open Drum Sander, press the red stop button (D).
OPERATIONAL GUIDELINES
When feeding workpiece through the Open Drum Sander, stand to the side and rest and hold the workpiece to be sanded on the feed belt.
Allow the feed belt to carry the workpiece into the drum. Once the workpiece is halfway through, reposition yourself to the outfeed side of the
Open Drum Sander to receive and control the workpiece as it exits the Open Drum Sander.
Support long workpieces with the folding infeed and outfeed tables in the up position. Never apply upward or downward pressure on the
workpiece as it is fed throught the Open Drum Sander, doing so may produce snipe in the sanded workpiece. To avoid bodily injury take special
care when sanding a workpiece that is twisted, bowed or otherwise varied in thickness from one end to another.
MAINTENANCE
MAINTENANCE
REPLACING DRUM SANDING BELT
Preparing and installing a new sanding belt on the drum is critical. The end of the
sanding belt gets installed to the left side of the drum first. Then the new sanding
belt is wrapped tightly around the drum, and fixed to the right side of the drum.
Once it is necessary to replace the sanding belt, obtain a replacement belt
through your nearest King Canada distributor. Follow these steps to cut the new
sanding belt, and then to remove the old belt and install a new sanding belt.
1) Refer to Fig.21 illustration as to how to cut the new sanding belt, the belt must
be cut at 15-3/4” diagonally, then cut the tapered end approximately 3” from the
edge as shown. Repeat for the opposite end of the sanding belt.
2) Open the top drum cover to access the used sanding belt. Squeeze the belt
retaining clip (A) Fig.22, do the same at the opposite end of the drum, now the
belt can be unwrapped and removed from the drum.
3) Now you are ready to install the new sanding belt. Start on the left (outboard)
side of the drum. Pinch or squeeze the retaining clip (A) Fig.22 and insert the
tapered end of the sanding belt through the slot and into the fastener so that it
uses most of the width of the slot. Release the retaining clip (A) to securely hold
the tapered end in the fastener.
4) Wrap the sanding belt around the drum, being careful not to overlap the
windings. Continue to wrap the sanding belt in a spiral fashion by rotating the
drum with your left hand and guiding the sanding belt with your right hand, refer
to Fig.23.
5) Pinch or squeeze the retaining clip (A) Fig.24 on the right (inboard) end of the
drum to open the clip, and pull the tensionner lever (B) to the top. Tightly insert
the tapered end of the sanding belt through the slot in the inboard (right) end
of the drum.
6) The inboard retaining clip fastener is designed to automatically take up any
slack caused by stretching of the sanding belt. If during use the sanding belt
stretches enough to allow the tensionner lever to reach its lowest position and
no longer maintain tension on the sanding belt, an adjustment is needed. If this
occurs then the tension is no longer maintained on the sanding belt. To fix this
reset the tensionner lever (B) Fig.24 by raising it, pushing the sanding belt
further into the slot and then releasing the clip.
HOW TO MAXIMIZE THE LIFEOFYOUR SANDING BELT
An Abrasive Cleaner (King accessory model KW-043) may be used to remove
deposits and help extend the life of the sanding belt. To use the cleaning stick,
operate the sanding drum with the dust cover open and dust collection on.
1) Hold the Abrasive Cleaner against the rotating drum and move it along the
drum surface.
2) Use a shop brush to remove any Abrasive Cleaner remnants from the drum
before resuming sanding operations.
