•This grinder is equipped with an approved 3-conductor cord rated at 300V
and a 3-prong, grounding type plug (See Figure 1) for your protection
against shock hazards.
•Grounding plug should be plugged directly into a properly installed and
grounded 3-prong grounding-type receptacle (See Figure 1).
•Do not remove or alter grounding prong in any manner. In the event of a
malfunction or breakdown, grounding provides a path of least resistance
for electrical shock.
WARNING: Do not permit fingers to touch the terminals of plug
when installing or removing from outlet.
•Plug must be plugged into matching outlet that is properly installed and
grounded in accordance with all local codes and ordinances. Do not
modify plug provided. If it will not fit in outlet, have proper outlet installed
by a qualified electrician.
•Inspect tool cords periodically, and, if damaged, have repaired by an
authorized service facility.
•Green (or green and yellow) conductor in cord is the grounding wire. If
repair or replacement of the electric cord or plug is necessary, do not
connect the green (or green and yellow) wire to a live terminal.
•Where a 2-prong wall receptacle is encountered, it must be replaced with
a properly grounded 3-prong receptacle installed in accordance with
National Electric Code and local codes and ordinances.
WARNING: This work should be performed by a qualified electrician.

•A temporary 3-prong to 2-prong grounding adapter (See Figure 2) is
available for connecting plugs to a two pole outlet if it is properly
grounded.
•Do not use a 3-prong to 2-prong grounding adapter unless permitted by
local and national codes and ordinances.
(A 3-prong to 2-prong grounding adapter is not permitted in Canada.)
Where permitted, the rigid green tab or terminal on the side of the adapter
must be securely connected to a permanent electrical ground such as a
properly grounded water pipe, a properly grounded outlet box or a properly
grounded wire system.
•Many cover plate screws, water pipes and outlet boxes are not properly
grounded. To ensure proper ground, grounding means must be tested by
a qualified electrician.
EXTENSION CORDS
•The use of any extension cord will cause some drop in voltage and loss of
power.
•Wires of the extension cord must be of sufficient size to carry the current
and maintain adequate voltage.
•Running the unit on voltages which are not within ±10% of the specified
voltage may cause overheating and motor burn-out.
•Use the table to determine the minimum wire size (A.W.G.) extension
cord.
•Use only 3-wire extension cords having 3-prong grounding type plugs and
3-pole receptacles which accept the tool plug.
•If the extension cord is worn, cut or damaged in any way, replace it
immediately.

MAINTENANCE
A properly maintained machine will give you years of satisfactory service,
whereas an abused machine will not. We strongly recommend that you observe
the following procedures for your own benefit and safety.
WARNING: Eye protection should always be worn by the operator
and others in the work area when servicing the machine.
Eye protection is required for protection from flying
debris and dust, which could cause eye injury.
DAILY AND WEEKLY MAINTENANCE
1. Clean your Supreme Bench Sander daily.
2. Shake dust bag and empty it daily.
The cleaner you keep the dust bag, the less likely you are to burn a hole in
them. Failure to shake the dust bag and empty it daily will only increase
this likelihood, but also cause a significant loss of dust extraction.
WARNING: Dust from Sander is combustible. Do not smoke while
cleaning the machine and dust collector.
Damaged dust bag will allow the escape of combustible
materials causing a fire hazard around the machine.
Check damaged parts. Before further use of a tool,
guard or other part that is damaged, check carefully to
determine that it will operate properly and perform its
intended function. Check for mounting or any other
condition that may affect its operation. A tool, guard or
other part that is harmfully damaged should be properly
repaired or replaced.
If the electrical cord, plug or wiring should become
frayed or damaged, replace it at once.
After making adjustments, remove all wrenches and
other tools before operating the Sander.
Use extra caution when starting the Sander for the first
time after installing a new tool or part.

MONTHLY MAINTENANCE
1. Take off the hose from the blower housing and look at the fan to see if
there are small particles stuck to the fan.
N.B. Those small particles can create vibrations of the bench sander.
2. Clean your dust bag with a shop vac or a vacuum cleaner.
N.B. You should change your dust bag at least every 2 years to increase the
efficiency of the dust collector.
LUBRICATION
Your Supreme Sander is equipped with sealed bearings throughout, which
should be replaced if they ever wear out.
Other parts should not require any lubrication, only cleaning the parts is required.
Lubrication will only attract dust and would be more harmful than helpful.
MOTOR REPLACEMENT
WARNING: Motor replacement requires working with electrical
wiring and can be hazardous. If you are not familiar with
electrical procedures, please call a qualified electrician.
To remove the motor, these procedures should be followed:
1. Disconnect the electrical power supply.
