Palmgren Operating Manual & Parts List 9681109 & 9681108
OPERATION (CONTINUED)
•
For optimum performance, do not stall motor or reduce speed.
Do not force the work into the abrasive.
•
Support workpiece with belt table when sanding with belt, with
disc table when sanding with disc.
•
Never push a sharp corner of workpiece rapidly against belt or
disc. Abrasive backing may tear.
•
Replace abrasives when they become loaded (glazed) or frayed.
•
When grinding metal, move workpiece across abrasive to
prevent heat build-up.
•
Never attempt wet sanding. If workpiece becomes too hot to
handle, cool it in water.
POSITION BELT TABLE
Refer to Figure 7.
The belt table can be tilted from 0° (at right angle to the table) to
45°. To adjust belt table position:
1. Unlock the handle on the right side of table.
2. Set the belt table to any angle between 0° and 45° using the
scale.
2. Lock the handle to secure belt table position.
WORK STOP
The work stop can be used instead of the belt table.
1. Remove belt table from the belt housing by loosening and re-
moving handle.
2. Mount workstop using bolt and washer which are located on
belt housing.
ADJUSTING BELT HOUSING
The belt housing can be positioned at a full vertical position, a full
horizontal position, or at any angle in between which is convenient
for the sanding operation.
To adjust belt housing position:
1. Loosen and remove four knobs.
2. Remove dust hoods.
3. Loosen hex nuts.
4. Move to the rear of the sander.
5. Gently push belt housing to move to the desired angle.
•
A positive stop bolt is provided to stop the belt housing at the
full horizontal position.
6. Tighten both hex nuts to secure belt housing position.
7. Replace dust hoods using the knobs.
HORIZONTAL BELT SANDING
Refer to Figure 8.
1. Adjust the belt housing to full horizontal position as described
in the above section, “Adjusting Belt Housing”.
2. Remove the belt table by removing handle.
3. Install work stop as described in “Work Stop”.
•
Idler drum can be used as a contact drum to sand curved sur-
faces. (Removing belt guard will be required.)
ABRASIVE BELT FINISHING
•
Finishing flat surfaces: Hold workpiece firmly with both hands;
keep fingers away from abrasive belt.
•
Use work stop. Work stop is used to position and secure work
being sanded. Keep end butted against work stop and move
work evenly across abrasive belt. Use extra caution when finish-
ing very thin pieces.
•
Finishing long pieces: remove work stop. Apply only enough
pressure to allow abrasive belt to remove material.
•
Finishing curved edges: Finish outside curves on flat portion of
abrasive belt. Finish inside curves on idler drum portion of abra-
sive belt.
•
Finishing end grain: It is more convenient to finish ends of long
workpieces with the abrasive belt in a vertical position.
•
Move work evenly across the belt.
•
For accuracy use miter gauge.
•
Adjust belt table angle for beveled work.
USING MITER GAUGE
•
The miter gauge is used on either the disc or belt table. Use the
miter gauge for securing the work and holding the proper
angle while sanding.
•
Adjust angle by repositioning the miter gauge. Loosen the knob
to reposition miter gauge.
•
Tighten the knob to secure miter gauge position.
•
Miter gauge assembly has a positive stop set-up for 90° and 45°
on either side.
•
To use the positive stop, loosen the knob, retract the indexing
pin, turn the miter gauge slightly, slide in indexing pin and turn
the miter gauge until the edge of the screw is stopped by the
indexing pin.
•
Check accuracy of miter gauge scale.
•
Use a combination square to adjust miter gauge square to disc.
Scale should be at zero. Loosen screw and reposition scale if
necessary.
