IMPORTANT SAFETY CONSIDERATIONS
DISC SANDER USE AND CARE
•Do not modify the Disc Sander in any way. Unauthorized modification may impair the function
and/or safety and could affect the life of the equipment. There are specific applications for which
the Disc Sander was designed.
•Always check of damaged or worn out parts before using the Disc Sander. Broken parts
will affect the Disc Sander operation. Replace or repair damaged or worn parts immediately.
•Store idle Disc Sander. When Disc Sander is not in use, store it in a secure place out of the
reach of children and other untrained persons. Tools are dangerous in the hands of untrained
users. Inspect it for good working condition prior to storage and before re-use.
•Use clamps (not included) or other practical ways to secure and support the workpiece to
a stable platform. Holding the work by hand or against your body is unstable and may lead to
loss of control.
•Do not force the tool. Use the correct tool for your application. The correct tool will do the
job better and safer at the rate for which it is designed.
•Do not use the power tool if the Power Switch does not turn it on or off. Any tool that cannot
be controlled with the Power Switch is dangerous and must be replaced.
•Disconnect the Power Cord Plug from the power source before making any adjustments,
changing accessories, or storing the tool. Such preventive safety measures reduce the risk
of starting the tool accidentally.
•Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools with
a sharp cutting edge are less likely to bind and are easier to control. Do not use a damaged tool.
Tag damaged tools “Do not use” until repaired.
•Check for misalignment or binding of moving parts, breakage of parts, and any other
condition that may affect the tool’s operation. If damaged, have the tool serviced before
using. Poorly maintained tools cause many accidents.
•Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool may become hazardous when used on another
tool.
SPECIFIC SAFETY RULES FOR DISC SANDER
•Maintain labels and nameplates on the Disc Sander. These carry important information.
•Always wear eye goggles and heavy work gloves when using the Sander. Using personal
safety devices reduce the risk for injury.
•Maintain a safe working environment. Keep the work area well lit. Make sure there is
adequate surrounding workspace. Always keep the work area free of obstructions, grease, oil,
trash, and other debris. Do not use a power tool in areas near flammable chemicals, dusts, and
vapors. Do not use this product in a damp or wet location.
•Avoid unintentional starting. Make sure you are prepared to begin work before turning on the
Disc Sander.

•Do not force the Sander. This tool will do the work better and safer at the speed and capacity
for which it was designed.
•Always unplug the Sander from its electrical outlet before performing any inspection,
maintenance, or cleaning procedures.
•Never leave the Sander unattended while running. Turn power off if you have to leave the
Disc Sander.
•Before each use, check all nuts, bolts, and screws for tightness. Vibration during mixing
may cause these to loosen.
•Keep extension cord off the ground and away from water.
•Always connect the Line Cord to a Ground Fault Circuit Interrupter protected electrical
outlet.
•Install this product on a proper surface. Locate on a flat, level, and solid surface that is
capable of supporting the weight of the Disc Sander.
•Always maintain a maximum of 1/16 inch clearance between the table and the sanding
Disc.
•Do not use the right side of the disc for sanding. The material could kick back.
•Hold material securely while sanding to avoid kick back.
•Use sander in a well ventilated area.
Work Area
•Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
•Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power tools create sparks, which may ignite the dust or
fumes.
•Keep bystanders, children, and visitors away while operating a power tool. Distractions
can cause you to lose control. Protect others in the work area from debris such as chips and
sparks. Provide barriers or shields as needed.
Electrical Safety
•Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and
refrigerators. There is an increased risk of electric shock if your body is grounded.
•Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
•Grounded tools must be plugged into an outlet properly installed and grounded in
accordance with all codes and ordinances. Never remove the grounding prong or modify
the plug in any way. Do not use any adapter plugs. Check with a qualified electrician if
you are in doubt as to whether the outlet is properly grounded. If the tools should electrically
malfunction or break down, grounding provides a low resistance path to carry electricity away
from the user.
•Do not abuse the Power Cord. Never use the Power Cord to carry the tools or pull the
Plug from an outlet. Keep the Power Cord away from heat, oil, sharp edges, or moving
parts. Replace damaged Power Cords immediately. Damaged Power Cords increase the risk
of electric shock.
•When operating a power tool outside, use an outdoor extension cord.

5
Personal Safety
•Stay alert. Watch what you are doing, and use common sense when operating a power
tool. Do not use a power tool while tired or under the influence of drugs, alcohol, or
medication. A moment of inattention while operating power tools may result in serious personal
injury.
•Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair,
clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be
caught in moving parts.
•Remove adjusting keys or wrenches before turning the power tool on. A wrench or a key
that is left attached to a rotating part of the power tool may result in personal injury.
•Do not overreach. Keep proper footing and balance at all times. Proper footing and balance
enables better control of the power tool in unexpected situations.
•Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard
hat, or hearing protection must be used for appropriate conditions.
Service
•Tool service must be performed only by qualified repair personnel. Service or maintenance
performed by unqualified personnel could result in a risk of injury.
•When servicing a tool, use only identical replacement parts. Follow instructions in the
“Inspection, Maintenance, And Cleaning” section of this manual. Use of unauthorized parts
or failure to follow maintenance instructions may create a risk of electric shock or injury.
GROUNDING INSTRUCTIONS
ELECTRICAL REQUIREMENTS
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.
The conductor with green insulation (with or without yellow stripes) is the equipment-grounding
conductor. If repair or replacement of the electric cord or plug is necessary, 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.

grounding provides a path of least resistance for electrical shock.
·GUIDELINES FOR EXTENSION CORDS
USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. 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 cause overheating.
Be 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 or wet areas.
ASSEMBLY INSTRUCTIONS
1. After unpacking the unit, fit the worktable to its mountings by means of two 1/4” bolts and
washers/spacers provided locating it with the two 1/4” studs, which allow the table to swivel.
2. The table may be set at any angle of depression from 0-45. To lower the table, unlock the 6 bolts
securely to lock the table in position. Next, fit the miter gauge, if required, by sliding it into the groove
provided on the worktable. To vary angel, unlock the 1/4” nut and set according to the scale.
3. If desired, the rubber suction pad supports on the base can be removed and the unit be secured
permanently to the bench by means of four wood screws and washers.
4. Never leave it running unattended. Always switch it off between operations or when inserting the
workpiece. Before attempting to adjust the worktable or change the grinding face. Always ensure
that the electricity supply is disconnected.
5. After switching off the motor allow the grinder to free wheel to a stop. Never attempt to stop it by
braking rotation with pressure applied to the disc.
6. Your universal grinder is designed so that cuts extracted away from the work surface, and therefore
requires only occasional cleaning. For this task, a paint brush or vacuum is recommended.
Otherwise, the unit is completely maintenance free and requires no further attention or inspection.
