Important Safety Demands For Sanders

Covington Engineering designs machines with safety in mind. Please read our Safety Demands Sheet carefully
and follow for your safety and the safety of others.

ELECTRICAL

Have your licensed electrician electrically ground your machines and equipment (against electrical shock) by
complying with federal, state, and local laws. Locate electrical and in-line switch or switches so operator can
immediately shut them off in an emergency.

DO NOT allow more than one person to operate a machine, unless you have a switch for each person, which is
wired so that any one of the switches will stop the machine in an emergency.

Keep children, visitors, and pets away from electrical devices and machinery.

DO NOT work in wet environments where electricity is present.

DO NOT plug into electricity until the motor switch is off and the proper voltage is supplied.

DO NOT leave motors running when not in use.

DO NOT wear jewelry or rings around electricity.

Keep all electrical cords away from moisture, rain, and moving parts.

Periodically check all cords for worn or frayed spots and replace or repair to code if needed.

Thermally protected motors will stop if overloaded. When they cool, they will start automatically without warning.
If the motor stops, shut the switch off for your protection.

USER SAFETY PRECAUTIONS

To avoid injury, protect yourself and others using the following guidelines. These are not exhaustive so please use
discretion and take every safety precaution when operating machinery.

1. Wear tight clothing. Loose clothes can be drawn into machinery.

2. Wear closed-toe shoes.

3. Wear safety goggles to protect your eyes from ying particles.

4. Loose hair is very dangerous because it can easily get caught in moving parts. Use a net or cap that will secure
your hair inside so it is not exposed to the machinery.

5. Keep your hands and ngers away from “danger spots” or “pinch points” where they might be injured.

6. Keep children, visitors, and pets away from machinery.

7. Use a respirator to protect yourself from particle inhalation.

8. Take off loose jewelry before using machines.

9. Be sure that all moving parts are shielded and all guards are in place before operating any equipment.

CHEMICAL

California Proposition 65 Warning -- For more information: www.P65Warnings.ca.gov

WARNING: Some of our products contain chemicals known to the State of California to cause

cancer and birth defects or other reproductive harm.

Very few people are allergic to lapidary and glass chemicals such as polishes, grits, abrasives, sawing solutions,
etc. If you show signs of rash or allergies of any kind when using any of the products, determine which one it is
and stop using it. Check with your doctor.

Keep all chemicals away from children and pets; never eat or drink these chemicals.

Keep all lapidary chemicals, grits, and glass sediment out of your sewer drains or they may clog.

MECHANICAL

IMPORTANT: NEVER MODIFY COVINGTON MACHINES – This will void all warranties and can be
very dangerous.

PINCH POINTS – Pinch points on machines can be varied and numerous. These include but are not limited to

areas with blades, belts, wheels, pulleys, discs, arbors, bearings, shafts, and other moving parts. This list is not
exhaustive so please use discretion and take every safety precaution when operating equipment or performing

maintenance. Specic pinch points on Covington’s vertical sanders also include the area behind the belt, between
the drums, as well as in front of the belt between the tool rest and the belt. Keep your ngers away from these

areas and do not wear loose clothes or hanging/dangling items near this machine as they can get caught and cause
severe injury.

Keep rags and foreign objects away from machines.

Be sure that all guards and/or covers are in place before running machines. Do not run your sander without the
belt guard securely attached to your machine.

Instructions For Vertical Sanders

INTRODUCTION

Covington’s Vertical Belt Sanders are designed for convenience

and versatility. These multi-purpose machines are among our most
popular sellers. Vertical sanders allow artists to create softer edges
on their pieces by using the space above the rigid backing plate, or

long ats by utilizing the backing plate behind the belt. Whether
you’re working glass or gemstones, Covington Sanders will take

you through deburring, shaping, cleaning, sharpening, smoothing,
and polishing your workpieces. These versatile units are an excellent
choice for beginners and professionals alike.

DESCRIPTION

Covington sanders are constructed of a heavy cast aluminum upright
and a base tank. Both bearings are shielded, double neoprene-sealed,
and greased for the life of the bearing. Each sander comes equipped with a 220g silicon carbide sanding belt. We

recommend purchasing a belt kit (one of each grit + an extra 100g) with your sander in order to experiment
with all of the grits. All Covington sanders come equipped with a backing plate and a brass valve for water hook-

up. Model numbers 464WBS and 466WBS accept 3” x 24” sand belts. Models 760WBS, 761WBS, and 764WBS
accept our 3” x 41-1/2” sand belts. We recommend purchasing a plumbing kit to make water hook-up easy.

SET UP

Safety: Before plugging in your unit, read the rst section of this packet labeled
Important Safety Demands for Sanders.

• Place your sander on a sturdy workbench or a Covington Sander Stand. If you
are using a sander stand, you will need to secure your sander to the stand using
the screws supplied with the purchase of the stand (see image 2 for proper

installation of screws). The stand can be anchored to the oor using lag-bolts

from your local hardware store (these are not provided with the purchase of the
stand).

• If you are using your sander for wet applications (ie. grinding glass or gemstones) you will need to hook up
your brass valve to a water supply. We also recommend replacing the plug on the front of your sander with

a drain kit. This allows you to have a “fresh water in - dirty water away” system that keeps your unit clean

and prevents cross-contamination issues. Your sander does not come with plumbing supplies for water hook
up or drainage. If you purchased a plumbing kit, everything you need will be included in the plumbing kit

box. You may also choose to hook up directly to a house water supply. The following installation instructions

will only apply to the hook-up of the tubing to the sander and will not cover
connection to your house water supply since that can vary widely.

• Your Covington Vertical Sander comes with a brass valve like the one pictured

in image 3. This style of valve accepts 1/4” O.D. tubing. In order to make your

valve water-tight, you will also need a brass insert (A) like the one sticking out
of the end of the tubing. To connect the tube to your valve, you must remove

the nut (B) and ferrule (C) from the valve (D), slide the nut onto the tube rst,

slide the ferrule onto the tube second, and slide the insert into the tube. Press
the tubing into the valve, push the nut up to the threads, and tighten the nut
