Keep work area clean and well lit. Cluttered or 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 children and bystanders away while operating a power
tool. Distractions can cause you to lose control.
Power tool plugs must match the outlet. Never modify the plug
in any way. Do not use any adapted plugs with earthed(grounded)
power tools. Modified plugs and un-matching outlets will increase
the risk of electric shock.
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.
Do not expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep it away from heat, oil, sharp edges
or moving parts.
When operating a power tool outdoors, use an extension cord
suitable for outdoor use. Use of a cord suitable for outdoor use
reduces the risk of electric shock.

This power tool is intended for sanding drywall for home use
only. Using this tool for professional purposes will reduce the
tool’s lifespan and cause parts to wear down sooner.
Do not force the machine to do other jobs, such as grinding,
cutting off, grooming, etc. Operations for which the tool is not
designed, including modification of the machine, may cause
machine damage, personal injuries, and invalidate the warranty.
Use of personal protective equipment is recommended to
reduce the risk of personal injuries. Use Safety goggles with side
shields, Ear protection such as plugs or muffs, Face mask or dust
mask to fight the debris produced by operation, Heavy-duty work
gloves to protect your hands and Safety non-slip work boots.
Keep bystanders and all other living creatures, away from the
work area. Do not operate the tool in the presence of flammable
liquids or gases. Do not operate the tool in wet or damp conditions.
Always hold your tool firmly with both hands to maintain
control and to avoid kickback. Never place your hand near the
rotating accessory. Do not position your body in the area where
power tool moves. The operator can control torque reactions or
kickback forces, if proper precautions are taken.
The rated speed of the accessories (rotating) must be at least
equal to the maximum speed of the power tool. Accessories
running faster than their rated speed can break and fly apart.
The outside diameter and the thickness of your accessory must
be within the capacity rating of your power tool. Incorrectly
sized accessories cannot be adequately guarded or controlled.
Keep the work area well ventilated. There is an LED Option on the
product itself. Ensure that the workplace lighting is adequate,
and/or provide extra lighting for the immediate work area.
DRYWALL SANDER SAFETY WARNINGS

Position the power supply cord out of rotating accessory. Do
not abuse the cord, never use the cord to carry the tools or pull
the plug from the outlet. Always make sure that any extension
cord you use is in good condition, and if used outdoors is of a
suitable type, and so labelled.
Use the vacuum dust extraction accessory in conjunction with
this sander. The workplace should be kept as clean and dust free
as possible. Do not connect a domestic vacuum cleaner to this
machine.
Use special care when working corners, sharp edges etc. Avoid
bouncing and snagging the accessory. Corners, sharp edges or
bouncing have a tendency to snag the rotating accessory and
cause loss of control or kickback.
Do not use accessories which are not specifically designed and
recommended by the tool manufacturer. Just because the
accessory can be attached to your power tool, it does not assure
safe operation.
Never lay the power tool down until the accessory has come to
a complete stop. The rotating accessory may grab the surface
and pull the power tool out of your control.
Do not use a damaged accessory. Before each use inspect the
accessory such as abrasive discs for chips and cracks, backing
pad for cracks, tear or excess wear. If power tool or accessory is
damaged, inspect for damage or install with a replaced accessory.
Threaded mounting of accessories must match the spindle
thread. Accessories that do not match the mounting hardware of
the power tool will run out of balance, vibrate excessively and
may cause loss of control.
Be extremely careful of dust disposal, materials in fine particle
form may be explosive. Do not throw sanding dust on an open
fire. Spontaneous combustion, may in time, result from a mixture
of oil or water with dust particles.
Regularly clean the power tool’s air vents. The motor’s fan will
draw the dust inside the housing and excessive accumulation of
powdered metal may cause electrical hazards.

The Drywall sander is a hand-held power tool suitable for
sanding plastered walls, ceilings, and interior walls, as well as
for removing paper residues, paint layers, coatings, adhesive
residues, and loose plaster. The device can also be used to sand
the floor as well. This is way durable, cost effective, easy to
install and use, altogether saves a lot of money and time.
The tool has a large surface area, a wide base. This makes
tackling those big walls easier as you are able to attack a larger
section of the wall at once.
This drywall sander has an in-built dust extraction accessory,
designed to collect all those fine plasterboard dust particles away
from the motor and then expel them into the attached bag.
There is an LED attachment on this product which shines light on
pits and imperfections on the wall, making it easy to re-sand
those problematic areas the minute you saw.
DS80-90 has an adjustable edge guard (a portion can be
detached from the guard), making it suitable for corners and all.
Unpack all parts and lay them on flat, stable surface. Remove all
packing materials. If you find that parts are missing or show
damage, do not use the product but contact your dealer.
Check if the tool is in good conditions by performing a quick
visual inspection. Ensure that you have all the accessories and
tools needed for assembly and operation.

extraction system.
The system is powered by an internal
fan attached to the motor, therefore
will only function while the tool is in
operation.
Rotate the extraction control to set the desired extraction speed.
Rotate the control clockwise fully for maximum suction and
counter clockwise for reduced suction.
EMPTYING THE DUST:
We recommend emptying dust bag after every sanding operation.
Remove the dust hose with dust bag from the sander’s dust port.
Hold the dust bag over a trash can. Remove the clasp (plastic slide
fastener) beneath the bag and empty the dust bag.
Attach the clasp back onto the rails of the dust bag, and re-attach
the dust hose and dust bag to the tool.

The Drywall Sander should always be held with both hands, one
on the trigger switch handle, and other on the side handle.
Adjust the carry straps on the dust bag for operator convenience
and comfort. Adopt the correct posture for the operation.
Let the sanding disc come to full speed before applying it onto
the work.
Switch the machine ON and position the sanding base lightly
against the work surface, and apply just enough pressure to align
the base with the work surface.
Gently apply more pressure to engage the rotating abrasive disc
onto the work surface.
Move the sander across the work surface in long overlapping
sweeps. Apply only enough pressure to keep the abrasive disc flat
against the work surface.
Excessive pressure should be avoided as it can cause swirl marks
and unevenness in the work surface.
Keep the sander in constant motion while the abrasive disc is in
contact with the work surface. Use a steady, sweeping motion,
allowing the rotating abrasive disc to float over the work surface.
Moving the sander erratically or concentrating for too long on one
area can cause swirl marks in the surface.
Once the sanding task has been completed, turn OFF the sander
by releasing the trigger. If the sander has been locked ON, press
down the lock button and trigger to release them, and your tool
will turn OFF. Wait for the base pad to stop rotating before setting
the tool down.
GENERAL OPERATION
