The Hi/Low Switch
THE CONTROLS
The On/Off Switch is on top of the sander. Turning the switch to “ON” starts the machine. Turning it
to “OFF” stops the machine.
The Hi/Low Switch is on the top-left hand side of the machine. Turn it to “High” and the machine
runs at maximum speed. Turn it to “Low” and the machine runs at a lower speed.
Use the high-speed setting for faster wood removal. Use the low-speed setting for finish cuts and
custom work.
The On/Off Switch

Page 4 Galaxy Floor Sanding Machines, Operator’s Manual
The Disc Guard is the lower casing that houses the sanding pad. It makes it possible to sand to the
edges of surfaces and along baseboards.
.
The Sandpaper Disc Holder is on the bottom of the sanding pad. It consists of a center bolt and
beveled washer and connects the sandpaper disc to the sanding pad.
The Special Wrench is held in the clamp on the back of the machine. It is used for changing the sandpaper
discs.

The Dust Bag is a high quality dust collector. It has a special wear-reducing surface on its floor-facing
side. You can attach it to the output end of the dust pipe by using the bag’s attached drawstring. Check
to ensue the bag is securely attached and the drawstring is not loosely hanging. You attach the bag’s
inlet to the dust pipe, draw the string and tie it. You can also attach it with the supplied bag clamp. You
place the bag’s inlet over the dust pipe’s output end and attach the bag clamp.
HOW TO PREPARE THE MACHINE FOR OPERATION
Warning: Always make sure the power switch is in the “OFF” position and the machine is unplugged
from the electrical source prior to doing any maintenance.
How To Install Sandpaper Discs
Always use the right sized sandpaper discs. This unit requires 7” diameter paper with a 7/8”center hole. To
replace the sandpaper disc follow these steps:
• Take off the special wrench that is clamped to the back of the machine.
• Put the machine upside down.
• Use the special wrench and remove the center bolt and beveled washer of the sandpaper holder. (To
loosen turn it counterclockwise). Take off the used sandpaper disc and place a new one on the sanding
pad. Fasten it with the sandpaper holder.

Types of Sandpaper Discs
• If you want to remove surface coatings from old floors such as varnish, wax polishes and stain
use 12 Grit. Do not use it on new even floors!
• If you want to do a first sanding of a new even floor use 36 Grit. You can use also use it for a
second sanding of old wood floor.
• If you want to do a final sanding on a new or old wooden floor use 80 Grit.
• If you want a very fine finish on any kind of floor use 120 Grit.
How to Adjust the Angle of the Sanding Pad to the Floor
The goal is to adjust the angle of the Sanding Pad so its front center part slightly touches the floor.
The process is the same on both sides. Follow these steps:
• Make sure you are on a flat surface. Use a ¾” crescent or open-ended wrench to twist off the
cap nuts on top of each caster adjusting shaft. (Turn counterclockwise).
• Loosen the locking nuts to provide for adjustment. Fit a flat screwdriver into the screw-slot of
an adjusting shaft. Turn it clockwise to heighten the caster. This puts more pressure towards the
outer edge of the sanding pad. Turn it counterclockwise to lower the caster. This puts more
pressure towards the center of the sanding pad. Adjust both sides until you have the desired
angle.
• Tighten the locking nuts. (Turn clockwise).
• Replace the cap nuts.
HOW TO OPERATE THE MACHINE
Operation Procedure
• Move the machine to your area of work. Inspect the area to ensure it is safe to work in. Remove
any obstacles and flammable substances. Use a hammer and punch to sink any floorboard nails.
• With the power switch in the “OFF” position connect the machine’s plug to the extension cord
and then to the electrical power source.
• Choose either the high or low speed position by flicking the high/low switch.

• Tilt the machine back by holding both handles so the sandpaper disc does not touch the floor.
• Put the power switch to the “ON” position.
• Keep the machine moving slightly from side to side as you lower the sandpaper disc to the
floor surface. Keep the machine moving as you sand the floor.
• Do not press down or apply weight to the machine. Its weight is sufficient for all types of
sanding.
MAINTENANCE
Warning: Only trained people should do routine maintenance. Repairs should only be done
at authorized service centers.
Warning: Always turn the power switch to the “OFF” position and disconnect the machine’s
electrical plug prior to doing any maintenance.
The Dust Control System
If you do not remove the dust from the dust bag when it is 1/3 full it can decrease the efficiency of the
dust control system. Always remove the dust each time you finish using the machine.
Removing Dust Pipe Obstructions
• Turn the power switch to the “OFF” position and unplug the machine from its electrical power
source.
• Remove the dust bag and empty the dust in an outside containable garbage disposer.
• Remove the screws that attach the dust pipe to the machine’s casing.
• Remove the dust pipe and inspect it for any clogs or obstacles. Clean the dust pipe and its port.
• Re-install the dust pipe.

How to Check and Replace the Carbon Brushes
The electric motor has two carbon brushes, one behind a front vent plate and the other behind a rear
vent plate. If replacement is required always replace both carbon brushes. Follow these steps:
• Turn the power switch to the “OFF” position and unplug the machine from its electrical power
source.
• Remove the screw on one of the vent plates. Slide it out of its grooved channel.
• Put your finger on the exposed metal tab. Push and release it to remove the Brush Holder
Spring. Pull on the copper shunt wire and the carbon brush will come out. Inspect it. If it is over
¼” in length and its wear is even it does not need to be replaced. Wipe it with a clean dry cloth
and push it back in. Push the Brush Holder Spring in and release it. It should stay locked in.
• If the carbon brush is less than ¼” in length or its wear is uneven it needs to be replaced. Pull
down on the wire as near as you can to the terminal. It will slide out. Reverse the procedure.
• Always replace both carbon brushes even if only one requires replacement.
