◊ ADDITIONAL SAFETY – WIDE ..
BELT SANDERS
The use of a wide belt sander is a source of serious
injury if basic safety rules are not followed. Be aware of
the following warnings:
◊ Pinch hazards
Be cautious when feeding a piece in the machine. Do
not place your fingers under the piece while feeding so
they could get caught between the piece and the
conveyor belt.
◊ trangulation hazards
Do not wear loose clothing, jewelry, large gloves and
tie back long hair. They could get pinched by rotating
parts.
◊ Contact with rotating sandpaper
Rotating sandpaper can cause important injuries very
rapidly. Keep hands away from rotating sandpaper at
all times during operation.
◊ Kickback
A piece can be ejected by the machine and hit the
operator. Do not stand in-line with the piece when
feeding, make sure the height is adjusted with respect
to the thickness of the piece so the pressure roller
maintains proper contact, and be careful about feeding
more than one piece at a time as the thickness might
be different and the pressure roller will not hold the
thinnest piece.
◊ Minimum dimensions
Never sand pieces that are below the minimum
dimensions to avoid kickback.
◊ Material
Do not sand any material other than wood.
◊ Dust
Sanding dust represents a health hazard and must be
seriously considered. Never operate the sander without
adequate dust collection system running. Wear eye
protection. Use respiratory protection if appropriate.

3. Remove the pad lock lever (B) by turning it
counterclockwise and pull it up.
4. Remove the pad block (C)
5. Remove existing belt (if present).
6. Make sure the direction of the arrows on the inside
of the belt matches the direction of rotation of the
machine (counter-clockwise). The edges of the
sanding belt should not be chipped or torn. Insert the
new belt starting first on the upper roller, then the lower
roller and center the belt while avoiding contact with the
limit switch fingers located on each side of the belt.
NOTE: the sanding belt must be centered between
the limit switches (D) and the edge of the belt must
be between the tongs of the oscillation controller
(E) before tensioning the belt, or damage may
occur tothe belt or to the sander when turned ON.
7. Replace pad block (C) and tighten pad lock lever (B).
8. Turn ON the belt tension knob (A).

Table Start key (J): oves the table to the entered value
Table Stop key (K): Stops table movement
etric/Imperial unit key (L): Press and hold the key for
10 seconds to switch between metric and imperial unit.
Press and hold the key for 3 seconds to calibrate the
display at the current board thickness.
ADJ STMENTS
◊ ANDING BELT TRACKING
The sanding belt tracking is the side movement
of the sanding belt while oscillating. The travel should
be equal on both ways and remain inside its normal
track, or the machine will stop.
Tracking was set at the factory, but might require
adjustment for example, after replacing sandpaper.
Tracking depends on the stream of air in the air fork
gap, on oscillation timing and on oscillation speed.
Adequate stream of air is required through the air flow
controller;
keep the holes clear as, if the jet of air is weak, the belt
will track away from the controller and into the limit
switch on the opposite end of the roller.

Page 13
The oscillation timing is the time it takes for the sanding
belt to oscillate from right-to-left and from left-to-right. This
oscillation should take the same amount of time. If
oscillation time to the left is, say 2 seconds, but time to the
right is longer, loosen the oscillation adjustment knob (M)
and move it to the right, until correct tracking is obtained.
Then tighten the adjustment knob.
The oscillation speed can be adjusted by means of the
speed controller (N) on the cylinder:
Loosen the fixing nut on the speed controller, then turn
the controller clockwise to decrease oscillation speed, or
turn counter-clockwise to increase. Tighten the fixing nut.
Different oscillating speeds give different sanding results,
some experiments might be required to obtain desired
result.
◊ ANDING PLATEN
The combi head has an adjustable felt platen with a
graphite pad. It is used during the finish sanding passes,
so during the rough sanding passes or dimensioning,
the platen is up and not used.
To adjust platen position, unlock the platen lock lever (A)
and adjust height by mean of the height lever (B). A
scale, divided in 0.1mm increments (approx. 0.004”),
helps in adjusting.
When at above 0, the platen is up and not used (for
roughing passes). Typically set at 1.5 mm up.
At 0, the platen is even with the sanding drum and is
used for intermediate finishing passes (typically 100-150
grit).
Under 0, the platen is lower than the sanding drum. It is
then doing the finish sanding (typically 180 and finer
grit). The platen should not be lowered by more than
0.2mm as burn marks and premature graphite wear will
occur.
During finish sanding passes, it is not necessary to use
the table height handwheel; adjusting the platen height
alone will be sufficient.
NOTICE:
The platen should always be kept clean after
sanding. If the workpiece has straight notches
across it, the graphite cloth and felt have worn out
and should be replaced immediately.

counter-clockwise to increase it.
IMPORTANT:
CHANGE THE FEED PEED ONLY WHILE
THE MACHINE I RUNNING.
FAILURE TO DO O MAY CAU E GEARBOX
DAMAGE.
◊ CONVEYOR BELT
The belt should always run at the center of the contact
drum. The belt tracking and tension are adjusted at the
factory.
However, should they require correction the adjustment
bolts are located on each side of the conveyor front
roller. Disconnect the machine from power. Turn the
bolts to increase/decrease the tension or correct the belt
tracking.
◊ V-BELT TEN ION
After the machine has been in operation for some time,
the V-belts might need to be re-adjusted.
Disconnect the machine from power. Remove the lower
right access door. Check the belt tension; each belt
should deflect by about 3/4”-1’’ when pushed moderately
at mid distance between the motor pulley and the roller
pulley.
If correction is required, raise or lower the motor base-
plate by mean of the tensioning bolt (P) and/or correct
the tension on the intermediate bender (Q).
NOTE: Keep V-belts correctly tensioned to
ensure proper functionality of emergency stop
brake (R). The emergency disc brake must be
able to stop the sanding drum.

◊ OVERVIEW
This section is only to provide a basic understanding on
how the sander is used. This supposes that the sander
is carefully checked, adjusted and in ready-to-run
condition.
This is not meant to be instructional. Should training be
required, ask your dealer for advice on sources that can
provide adequate training on use of a wide belt sander.
The basic operating procedure is as follows:
1. Place the workpiece on the conveyor belt and
underneath the sanding belt.
2. Raise the table to approximate workpiece thickness.
3. Remove the workpiece. Start the dust collector, the
sanding belt, then start the conveyor belt.
4. Carefully feed workpiece into the sander, supporting the
back of the piece until supported by pressure rollers.
5. During initial pass with a new piece, adjust the table
height so the piece has a very light contact with the
sanding belt.
Determining the depth of wood removal is one of the
most important procedures for the sander. It may take
some experimentation to determine the proper depth,
given the variables of abrasive grit, type of wood, feed
rate, platen position. The ammeter also helps in
estimating the load applied to the abrasive. To prevent
unnecessary wear of the sanding belt, the wood piece
should be surface planed before sanding.
Never remove lots of material in a single pass. As a
general rule, 1/64” (0.4mm) is suggested for coarser
grits and softer woods, while 1/128” (0.2mm) may be
preferable with finer grits and harder woods. For best
results, use scrap pieces of wood to practice on. This
will help you develop a familiarity with the machine
before doing finish work on good pieces.
6. Receive the workpiece from the outfeed side of the
conveyor.
7. If needed, raise the conveyor table by a small amount
and repeat feeding process through the sander.
8. Stop the machine and change the sandpaper to a finer
grit and repeat feeding process.
9. When sanding is complete, stop the sander and the dust
collector; disconnect the sander from the power.
◊ U ING THE PLATEN
The sander is equipped with a platen with a graphite
pad. It is used during finish sanding to create a buffed
like look and prepare the piece for final hand sanding
and finish coat.
Please refer to previous section Adjustments/Platen.
◊ GRIT ELECTION
The grit size of the sandpaper designates the
coarseness of the abrasive. The lower the grit number,
the coarser the abrasive. With coarser grit papers, such
as 60 grit, very aggressive material removal and surface
scratching occur.
With finer grit abrasives, very little material is
removed and a buffed like look begins to appear.
The table below shows different types of grit and their
uses.
ABRA IVE NORMAL U E
60 Grit surfacing and dimensioning boards,
truing warped boards
80-100 Grit surfacing, light dimensioning,
removing planer ripples
120 Grit light surfacing, minimal stock removal
150 Grit finish sanding, minimal stock removal
180 Grit finish sanding only, no stock removal
The general rule of thumb is to sand a workpiece with
gradually higher grit numbers, with no one grit increase
higher than 50 (ex. 100-150). The type of wood and the
desired finish will determine the grit to use.

MAINTENANCE
◊ LUBRICATION AND MAINTENANCE
1. The machine interior should be thoroughly cleaned
every day after work. Remove the sanding belts before
cleaning and replace them afterwards.
2. The bearings should be greased after every 100 hrs of
use.
3. The water should be drained from the filter cups
regularly.
4. onthly, apply a good amount of grease on the table
elevation screws, and apply grease to the chain and
gears mechanism. Pay attention not to put grease on
the V-belts.
5. The oil in the gear reducer should be changed after the
first 300 hours, and every 2500 hours of use thereafter.
6. Test the safety features on a regular basis.
7. Check for damaged or worn sanding belts. Replace if
required.
