GENERAL SAFETY WARNINGS
IMPORTANT SAFETY INSTRUCTIONS
WARNING
Before using this tool orany of itsaccessories, read this manual and follow
all Safety Rules and Operating Instructions. The important precautions, safeguards
and instructions appearing in this manual are not meant to cover all possible situations.
It must be understood that common sense and caution are factors which cannot
be built into the product.
EYE, EAR & LUNG PROTECTION
SYMBOL MEANING
ALWAYS WEAR EYE PROTECTION THAT CONFORMS
WITH CSA Z94.3 or ANSI SAFETY STANDARD Z87.1
FLYING DEBRIS can cause permanent eye damage.
Prescription eyeglasses ARE NOT a replacement for proper
eye protection. The usage of a safety standard compliant
face shield placed over proper safety glasses or goggles
can reduce the risk of facial injury.
Non-compliant eyewear can cause serious injury if broken
during the operation of a power tool.
Use hearing protection, particularly during extended periods
of operation of the tool, or if the operation is noisy.
WEAR A DUST MASK THAT IS DESIGNED TO BE
USED WHEN OPERATING A POWER TOOL IN A
DUSTY ENVIRONMENT.
Dust that is created by power sanding, sawing, grinding,
drilling, and other construction activities may contain
chemicals that are known to cause cancer, birth defects,
or other genetic abnormalities. These chemicals include:
• Lead from lead-based paints
• Crystalline silica from bricks, cement, and other
masonry products
• Arsenic and chromium from chemically treated lumber
The level of risk from exposure to these chemicals varies,
according to how often this type of work is performed. In
order to reduce exposure to these chemicals, work in a
well-ventilated area, and use approved safety equipment,
such as a dust mask that is specifically designed to filter
out microscopic particles.

WARNING
Read all safety warnings, instructions, illustrations and specifications provided
with this power tool. Failure to follow all instructions listed below may result
in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
Always use safety glasses, ear protection and a dust mask when operating the tool.
The term “power tool” in the warnings refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any way.
Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your body
is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging
the power tool. Keep cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
e) When operatinga power tool outdoors, usean extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in adamp location is unavoidable, use a residual current
device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use common sense when operating
a power tool. Do not use a power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inattention while operating power
tools may result in serious personal injury.

5" RANDOM ORBIT SANDER
c)
connecting to power source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the switch or energizing power
tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on.
A wrench or a key left attached to a rotating part of the power tool may result
in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair and
clothing away from moving parts. Loose clothes, jewellery or long hair can
be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of dust collection
can reduce dust-related hazards.
h) Do not let familiarity gained from frequent use of tools allow you to become
complacent and ignore tool safety principles. A careless action can cause
severe injury within a fraction of a second.
4) Power tool use and care
a)
Do not force the powertool. Use the correct power tool for your application.The correct
power tool will do the job better and safer at the rate for which it was designed.
b)
tool that cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or remove the battery pack,
if detachable, from the power tool before making any adjustments, changing
accessories, or storing power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained users.
e) Maintain power tools and accessories. Check for misalignment or binding
the power tool’s operation. If damaged, have the power tool repaired before
use. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in accordance with these
instructions, taking into account the working conditions and the work to be
could result in a hazardous situation.
h) Keep handles and grasping surfaces dry, clean and free from oil and grease.
Slippery handles and grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
5) Service
Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power tool
is maintained.

GUIDELINES FOR EXENSION CORDS
Make sure your extension cord is the proper size. When using an extension cord,
be sure to use one heavy enough to carry the current the tool will draw. An undersized
cord will cause a drop in line voltage resulting in loss of power and overheating.
The table below showsthe correct size to use according to cord length and
nameplate ampere rating. Ifin doubt, use the next heavier gauge.The smaller
the gauge number the heavier the cord.
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 electrician before
using it. Protect your extension cord from sharp objects, excessive heat and damp
or wet areas.
Use a separate electrical circuit for your power tools. This circuit must not
be less than 14 gauge wire and should be protected with either a 15A time delay
fuse or circuit breaker. Before connecting the power tool to the power source,
make sure the switch is in the OFF position and the power source is the same
as indicated on the nameplate. Running at lower voltage will damage the motor.
When operating a power tool outdoors, use an outdoor extension cord marked
“W-A” or “W”. These cords are rated for outdoor use and reduce the risk of electric
shock.
WARNING
Keep the extension cord clear of the working area. Position the cord so it will
not get caught on the workpiece, tools or any other obstructions while you are
working with the power tool.
WARNING
Repair or replace damaged or worn extension cords immediately.
Select the appropriate extension cord gauge and length using the chart below.

ASSEMBLING AND OPERATING
SANDING DISC SELECTION
Make sure you select the correct size and style of sanding disc for your sander.
The correct disc will:
• Have a diameter of 5"
• Have a row of eight 3/8" holes that match the hole pattern in the sander base.
• Have a backing for use with the hook & loop disc attachment system.
Selecting the correct grit and type of sandpaper is extremely important in achieving
a high-quality sanded finish. Aluminum oxide, silicon carbide and other synthetic
abrasives are best for power sanding. Natural abrasives such as flint and garnet
are too soft for economical use in power sanding.
In general, coarse grit will remove most material. Fine grit will produce the best
finish in all sanding operations. The condition of the surface to be sanded will
determine which grit will do the best job.
NOTE:
Where the sanding disc grits are shown numerically, higher numbers indicate
finer grit and lower numbers indicate coarser grit.
If the surface is rough, start with a coarse grit and sand until the surface is uniform.
Medium grit may then be used to remove scratches left by the coarser grit.
Fine grit should be used for finishing the surface.Always continue sanding with
each grit until the surface is uniform.
SANDING
Clamp or otherwisesecure your workpiece to prevent it from moving under
the sander while being sanded. Secure the workpiece in a vice if possible.
WARNING
Any unsecured workpiece could be thrown toward the operator causing injury.
Place the sander on the workpiece so the complete sanding disc surface is in
contact with the workpiece. Turn the sander ON by pressing on the left-hand side
of the ON/OFF switch. Move the sander slowly over the workpiece making successive
passes in parallel lines, circles or crosswise movements. Because the random
orbital motion of the sanding disc moves in tiny circles, it is not necessary to move
the sander with the grain or in the same direction for successive passes (Fig. 6).
CLEAN THE DUST BAG OFTEN
sanding dust.
DO NOT FORCE THE SANDER. The weight of the sander usually provides adequate
pressure. Let the sander and the sanding disc do the work. Applying added pressure
will slow the motor, increase the wear on the sandpaper and greatly reduce the
sander speed. Excessive pressure will overload the motor causing possible damage
from the motor overheating. It will also create an inferior finish on sanded work.
Any finish or resin on wood will soften from the frictional heat, causing sandpaper
to become clogged quickly. Do not sand in one spot too long as the sander’s rapid
action may remove too much material, making the surface uneven.

14
1262-000
5" RANDOM ORBIT SANDER
Clean the Dust Bag Often – Continued
Extended periods of sanding may tend to overheat the motor. If this occurs,
turn the sander OFF, wait until the sanding disc comes to a complete stop
and remove it from the workpiece. Check to make sure your hands have not
been covering the cooling vents. Let the motor cool before continuing the
sanding operation.
MAINTENANCE
WARNING
When servicing, use only identical replacement parts. The use of any other part
may create a hazard or cause product damage.

Maintenance – Continued
NOTE:
It has been found that electric tools are subjected to accelerated wear and possible
premature failure when they are used on fiberglass boats and sports cars, wallboard,
spackling compounds or plaster. The chips and grindings from these materials
are highly abrasive to electric tool parts such as bearings, brushes, commutators,
etc. Consequently, it is not recommendedthat this tool be used for extended
work on any fiberglassmaterial, wallboard, spackling compounds or plaster.
During any use on these materials it is extremely important that the tool is cleaned
frequently by blowing it out with an air jet.
WARNING
Always wear safety goggles or safety glasses with side shields during all sanding
operations. It is criticalthat you also wear safety goggles or safety glasses
with side shields and a dust mask while blowing dust out of the sanderwith
an air jet. Failure to take these safety precautions could result in permanent eye
or lung damage.
LUBRICATION
