1. This sander is designed to sand wood or
wood-like products only. Sanding or grinding
other materials could result in fire, injury, or
damage to the workpiece.
2. Use the sander on horizontal surfaces only.
Operating the sander when mounted on non-
horizontal surfaces may result in motor damage
or injury.
3. Make sure the sanding belt is installed in the
correct direction. See directional arrow on back
of belt. Feed workpieces against the direction of
the rotation for maximum safety.
4. Keep hands away from the drum and belt
during operation. Do not touch moving pieces.
If cleaning is necessary, use a brush to remove
sawdust and chips instead of your hands.
5. Do not use sanding belts or drums that are
damaged, torn, or loose. Use only the correct
size sanding belt.
6. Always hold the workpiece firmly when
sanding. Keep hands away from sanding belt or
spindle. Sand only one workpiece at a time.
7. Always hold the workpiece firmly on the table
when using the sander.
8. Allow spindle to reach full speed before
sanding. Do not forcefully jam a workpiece into
the sanding surface. Firmly hold the workpiece
and lightly ease it against the spindle.
9. Always maintain a minimum clearance of
1/16 inch (1.6 mm) or less between the table
and the sanding belt.
10. Replace worn or damaged belts before

Section 2: Electrical Information
Electrical Requirements
Power Supply And Motor Specifications:
Warning: To avoid electrical hazards, fire
hazards, or damage to the tool, use proper
circuit protection. Use a separate electrical
circuit for your tools. To avoid shock or fire, if
power cord is worn or cut, or damaged in any
way, have it replaced immediately.
Grounding Instructions:
Warning: This tool must be grounded while
in use to protect the operator from electrical
shock.
In The Event Of A Malfunction Or Breakdown,
grounding provides a path of least
resistance for electric current and reduces
the risk of electric shock. This tool is equipped
with an electric cord that has an equipment-
grounding conductor and a grounding plug.
The plug MUST be plugged into a matching
receptacle that is properly installed and
grounded in accordance with ALL local codes
and ordinances.
Do Not Modify The Plug Provided. If it will not
fit the receptacle, have the proper receptacle
installed by a qualified electrician.
Improper Connection of the equipment-
grounding conductor can result in risk of
electric shock.
Do Not connect the equipment-grounding
conductor to a live terminal.
Check with a qualified electrician or service
person if you do not completely understand the
grounding instructions, or if you are not sure the
tool is properly grounded.
Electrical Information
Extension Cords
Grounded Tools require a three wire
extension cord.
Double Insulated Tools can use either a two or
three wire extension cord.
As the distance from the supply outlet
increases, you must use a Heavier Gauge
Extension cord.
Using extension cords with Inadequately
Sized Wire Causes A Serious Drop In Voltage,
Resulting In Loss Of Power And Possible Tool
Damage. Refer to the table shown to determine
the required minimum wire size.
The smaller the gauge number of the wire, the
greater the capacity of the cord. For example,
a 1.628mm(14 gauge) cord can carry a higher
current than a 1.291mm(16 gauge) cord.
When using More Than One Extension Cord
to make up the total length, be sure each
cord contains at least the minimum wire size
required.
If you are using One Extension cord for more
than one tool, add the nameplate amperes
and use the sum to determine the required
minimum wire size.
10
Guidelines & Recommendations
for Extension Cords
When Using An Extension Cord, be sure to
use one heavy enough to carry the current
your product will draw. An undersized cord will
cause a drop in line voltage resulting in loss of
power and overheating. The table below shows
the correct size to be used according to cord
length and ampere rating. When In Doubt, Use
A Heavier Cord. The smaller the gauge number,
the heavier the cord.
Make sure your extension cord is Properly
Wired And In Good Condition. Always replace a
damaged extension cord or have it repaired by
a qualified person before using it. Protect your
extension cords from sharp objects, excessive
heat and damp/wet areas.

Section 5: Opperation
Operation
16
Spindle Sanding
Spindle sanding is the preferred method of
removing material from inside curves and
irregular edges. The oscillating spindle moves up
and down as it rotates to help smooth surfaces
more quickly and evenly than a non-oscillating
sander.
To use the spindle sander, you must first
configure the machine for spindle sanding by
installing the appropriate sanding drum/sleeve
for your operation.
Installing A Sanding Drum And
Sleeve (Fig. F)
To ensure the workpiece is supported during
spindle sanding operations, make sure to use
the table insert and throat plate that best
matches the drum and sleeve that you’ll be
working with.
The following table can help ensure that you are
using the proper sizes of throat plates, drums
and washers for each respective sanding sleeve.
Keep in mind the smallest size sanding sleeve
does not include a drum. It instead goes directly
onto the bare spindle.
1. Disconnect the machine from the power
source.
2. Use the table to the right to select the
required size of components for the sanding
drum and sleeve size you have chosen.
3. Place the table insert into the table opening.
Install the preferred drum onto the spindle
shaft, followed by the corresponding
sanding sleeve and throat plate (Fig. F).
4. Secure the sanding drum in place with
the corresponding washer and nut (Fig.F).
Tighten the nut until the sanding drum
creates equal pressure to all sides of the
sanding sleeve. The sleeve should not be
able to freely rotate without also rotating
the sanding drum.
Fig. F.
Fig. G.
Operation
