7) Additional Safety instruction for Air Sanders
1. Hold air tool by insulated gripping surfaces, as the sanding pad may contact its own air hose. Cutting a “live” air hose may
cause hose to rupture and pose a hazard to yourself and others.
2. Disposing of dust. 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.
3. Always wear eye protection and a dust mask for dusty applications and when sanding overhead. Sanding particles can be
absorbed by your eyes and inhaled easily and may cause health complications.
4. Use special precautions when sanding chemically pressure treated timber, paint that may be lead based, or any other
materials that may contain carcinogens. A suitable breathing respirator and protective clothing must be worn by all persons
entering the work area. Work should be sealed by plastic sheeting and persons not protected should be kept out until work area
is thoroughly cleaned.
5. Do not ‘wet sand’ with this sander. Liquids entering the motor housing will cause corrosion.
6. Do not use sandpaper intended for larger sanding pads. Larger sandpaper will extend beyond the sanding pad causing
snagging, tearing of the paper or kick-back. Extra paper extending beyond the sanding pad can also cause serious lacerations.
WARNING! Some dust created by power sanding, sawing, grinding, drilling and other construction activities contain
chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
• Lead from lead-based paints;
• Crystalline silica from bricks, cement and other masonry products, and;
• Arsenic and chromium from chemically-treated timber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals:
work in a well-ventilated area and work with approved safety equipment, such as dust masks that are specially designed to filter out
microscopic particles.
8) Before Starting
TO PREVENT SERIOUS INJURY FROM EXPLOSION:
Verify compressor is off before setup. Use only clean, dry, regulated,
compressed air to power this tool. Do not use oxygen, carbon dioxide,
combustible gases, or any other bottled gas as a power source for
this tool.
1. It is recommended a filter, regulator with pressure gauge, oiler,
in-line shut-off valve, and quick coupler be fitted for optimal
operation, as shown on Figure A.
2. An in-line shut-off ball valve is an important safety device,
it will shut-off the air supply even if the air hose is ruptured.
The shut-off valve should be a ball valve because it can be
closed quickly.
Note: If an automatic oiler system is not used, add a 4 to 5 drops of
Kincrome Air Tool Oil to the air inlet (7) before operation.
Add 1-2 more drops every hour of continual use.
3. Attach an air hose to the compressor’s air outlet. Connect the air hose to the air inlet (7) of the tool. Other components, such as
a quick connect fitting and quick connect coupler, will make operation more efficient, but are not required.
WARNING! Do not install a quick coupler directly on the tool. Couplers contains an air valve that will allow the air tool to
retain pressure and inadvertently operate after the air supply is disconnected.
4. The air hose must be long enough to reach the work area and allow free movement while working.
5. Turn on the air compressor according to the manufacturer’s directions and allow the tank to build up pressure until it cuts-off.
6. Adjust the air compressor’s regulator so that the air output is at the tools recommended working pressure, the output must not
exceed the tool’s maximum air pressure at any time. Adjust the pressure gradually, while checking the air output gauge to set
the optimal pressure range.
7. Inspect all air connections for leaks. Repair any leaks.
8. If the tool is not be used, turn off and detach the air supply, safely discharge any residual air pressure, and release the
trigger (9) and/or turn the tools switch to its off position to prevent inadvertent operation.

9) Assembly
Assembling the Dust Bag directly to the sander.
1. Disconnect the air hose from the air inlet (3) and feed the air hose through the loop on the dust bag (1).
Note: This will keep the dust bag (1) away from the sander while in operation.
2. Get the dust bag (1) and feed the open end over the vacuum port (8).
3. Once it has been fed over the vacuum port (8), tie up the dust bags (1) laces to secure the dust bag (2) to the sander.
Note: Do not leave hanging dust bag (1) laces free, as they will get caught by the hook & loop pad (5)
Assembling the Dust Bag Via the Extraction Hose
1. Get the vacuum hose (2) and fit either end of it over the vacuum port (8) of the sander.
2. Get the dust bag (1) and feed the open end over the vacuum hose (8).
3. Once it has been fed over the vacuum hose (2), tie up the dust bags (1) laces to secure the dust bag (1) to the hose.
Assembly for use with Auxiliary Dust Extraction system.
1. Get the vacuum hose (2) and fit either end of it over the vacuum port (8) of the sander.
2. Get the free end of the vacuum hose (2) and feed into your vacuum wand.
Note: All vacuum wands vary, so an adaptor may be required.
Note: You must turn on your vacuum for the vacuum hose (2) to operate effectively.
Attaching/Removing a sanding pad
1. Firstly detach the Random Orbit Sander from the air supply.
2. Carefully peel paper backing from the pressure sensitive adhesive type sanding disc.
3. Align holes on sanding disc with holes on the hook & loop pad (5) , then carefully press sticky side of disc against pad as
tight as possible.
Note: Holes in sanding disc must line up with holes in the hook & loop pad (5) in order for the self generating vacuum feature of your
sander to function properly.
Note: It is recommended that you clean the hook & loop pad (5) occasionally by brushing lightly with a small brush, or micro-fibre
cloth. Dust build-up on the hook & loop pad (5) could cause sanding disc not to stick properly.
10) Operation
Sandpaper Selection
Selecting the correct grit of sandpaper is an important step in achieving optimum results. Coarse grit will remove the most material.
Finer grit will produce a smoother finish. The condition of the workpiece will determine the grit of the sandpaper to be used. The
higher the grit number, the finer the grade of sandpaper.
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. Finer grit is then used to finish the surface. Always continue sanding with each grade of sandpaper
until the surface is uniform.
Sanding Tips
Never force the sander. The weight of the sander supplies adequate pressure, allowing the sandpaper to do the work.
Applying additional pressure will greatly reduce the sander speed, rapidly wear the sandpaper. This will slow the removal rate,
sander’s rapid action may remove too much material, creating an uneven surface and a poor finish
The random orbital action of your sander allows you to sand with the grain, or at any angle across it for most sanding jobs. In the final
stages a better finish will be achieved by sanding with the grain.
1. Screw in Nitto Style Fitting (9) to the air inlet (3). Thread (teflon) tape may be required to ensure a leak free seal.
2. The ultimate speed of the sander can be adjusted up or down by turning the speed lever (4) to the left or right.
3. Select the most suitable sanding paper for the job at hand, and attach to hook & loop pad (5) as stated in the
“Assembly; Adding/Remvoing Sanding Pads section of this manual”.

INDUSTRIAL RANDOM ORBITAL SANDER INDUSTRIAL RANDOM ORBITAL SANDER
4. Once you have selected the suitable abrasive disc start the random orbit sander by holding down the trigger (7) and bring the
hook & loop pad (5), slowly and evenly to the surface of the material. Moving the sanding disc back and forth overlapping the
desired area.
5. Remove the sander from the work surface before stopping the sander.
6. Note: Regularly check the hook & loop pad (5) for wear, always change a cracked or damaged disc.
7. If random orbit sander requires more power to accomplish task, ensure that the tool is receiving sufficient, un-obstructed
airflow and/or increase the speed of the sanding pad, by rotating the speed lever (4) to the left or right.
8. Increase/decrease the pressure (PSI) output of regulator ensuring you do not exceed the rated maximum inlet air pressure of
the tool (90PSI).
Caution: If tool still does not have sufficient force at maximum pressure and sufficient airflow, then a larger
tool may be required.
11) Cleaning, Maintenance, and Lubrication
Note: These procedures are in addition to the regular checks and maintenance explained as part of the regular operation of the
air-operated tool. The air motor and bearing uses compressed air to power the tool. Moisture in compressed air will rust the motor
components, you must lubricate the motor with Kincrome Air Tool Oil daily.
Cleaning
1. Regularly blow dirt and dust out of all air vents with clean, dry air at least once a week. To minimize the risk of eye injury,
always wear approved eye protection.
WARNING! Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the tool.
These chemicals may weaken the plastic materials used in these parts. Use a cloth dampened only with water and mild
soap. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.
Lubrication
Note: Remove vacuum hose (2) from vacuum port/exhaust (8) before lubricating the Random Orbital Sander.
1. Disconnect the tool from the air supply holding it so the air inlet (3) faces up.
2. Hold the trigger (7) down and put 4 to 5 drops of Kincrome Air Tool Oil in the air inlet. Holding the trigger (7) down helps
circulate oil in the motor.
3. Connect the tool to air supply, cover the vacuum port/exhaust (8) with a towel and run for a few seconds.
WARNING! Any excess oil in the motor is immediately expelled from the vacuum port/exhaust (8) .Always face the
vacuum port/exhaust (8) away from people or objects.
Storage
1. Avoid storing the tool in a location subject to high humidity. If the tool is left as it is used, the residual moisture inside the tool
can cause rust. Before storing and after operation, oil the tool and run it for a short time.
2. Regular inspection should be carried out of sanding pads, spindles, threads, and clamping devices irrespect of wear.
