3Avoid unintentional starting.
pWARNING! Ensure correct air pressure is maintained and not exceeded. Recommended pressure 70-90psi.
3Keep air hose away from heat, oil and sharp edges. Check air hose for wear before each use and ensure
that all connections are secure.
3Prolonged exposure to vibration from this sander poses a health risk. It is the owner’s responsibility to
correctly assess the potential hazard and issue guidelines for safe periods of use and offer suitable
protective equipment.
7DO NOT use the sander for a task it is not designed to perform.

INSTRUCTIONS FOR:
AIR ORBITAL SANDER
MINI DISC 50mm
MODEL No: SA70
Original Language Version SA70 Issue: 1 - 23/05/11

2. INTRODUCTION & SPECIFICATION
3.1. Air Supply
3.1.1. Ensure the sander air valve (or throttle) is in the "Off" position before connecting to the air supply.
3.1.2. You will require an air pressure between 70-90psi, and an air flow according to the specification above.
3.1.3. pWARNING! Ensure the air supply is clean and does not exceed 90psi while operating the sander.
Too high an air pressure and/or unclean air will shorten the product life due to excessive wear, and may
be dangerous, causing damage and/or personal injury.
3.1.4. Drain the air tank daily. Water in the air line will damage the sander and will invalidate your warranty.
3.1.5. Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig. 1.
3.1.6. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres).
The minimum hose diameter should be 1/4” I.D. and fittings must have the same inside dimensions.
3.1.7. Keep hose away from heat, oil and sharp edges. Check hoses for wear and make certain that all
connections are secure.
3.2. Couplings
Vibration may cause failure if a quick change coupling is connected directly to the
air sander. To overcome this, connect a leader hose to the sander. A quick change
coupling may then be used to connect the leader hose to the air line recoil hose.
See figs. 1 & 2.
3. PREPARING SANDER FOR USE
1.2. LEAD PAINT WARNING!
Paint once contained lead as a traditional ingredient. The dust caused by the removal of such paint is
toxic and must therefore be avoided. The following action must be taken before using the sander on
a surface that you suspect may contain lead paint.
1. User must determine potential hazard relating to age of paint to be removed (modern paints do
not have lead content).
2. DANGER! Keep all persons and pets away from the working area. The following are particularly
vulnerable to the effects of lead paint dust: Pregnant women, babies and children.
3. We recommend personal protection by using the following safety items:
a) Paint Spray Respirator (Our ref SSP16EN)
b) PE Coated Hooded Coverall (Our ref SSP267). c) Latex Gloves (Our ref SSP24).
4. Take adequate measures to contain the paint dust, flakes and scrapings.
5. Continue to wear safety equipment as in (3) and thoroughly clean all areas when task is complete.
6. Ensure paint waste is disposed of in sealed bags or containers.

p WARNING!Disconnect sander from air supply before changing accessories, servicing or performing
maintenance.Replace or repair damaged parts. Use genuine parts only. Unauthorised parts may be
dangerous and will invalidate the warranty.
5.1. If the air supply does not have an oiler lubricate the air sander daily with a few drops of good grade air
tool oil such as Sealey ATO/500 or ATO/1000, dripped into the air inlet before use.
5.2. Clean the sander after use and change pads when required.
5.3. Loss of power or erratic action may be due to the following:
a) Excessive drain on the air line. Moisture or restriction in the air pipe. Incorrect size or type of hose
connectors. To remedy check the air supply and follow instructions in Section 3.
b) Grit or gum deposits in the sander may also reduce performance. If your model has an air strainer
(located in the area of the air inlet), remove the strainer and clean it. Flush the sander out with gum
solvent oil or an equal mixture of SAE No 10 oil and kerosene. Allow to dry before use.
If problems continue, contact your local Sealey service agent.
5.4. For a full service contact your local Sealey service agent.
5.5. When not in use, disconnect from air supply, clean sander and store in a safe, dry, childproof location.
4. OPERATING INSTRUCTIONS
5. MAINTENANCE
pWARNING! Ensure you read, understand and apply the safety instructions in Section 1 before use.
4.1. Assembly
4.1.1. Fit backing pad and sanding disc. Use only discs with speed ratings equal to or higher than the speed
rating of the sander. DO NOT use cloth backed sanding discs.
4.1.2. Connect air supply to sander, press the control valve lever and check that the sander is working correctly.
4.1.3. The air flow may be regulated by adjusting the regulator valve in the back of the handle.
4.2. Operating
The sander is designed to provide a combined “rotary” and “random orbit” action.
Always use a grit appropriate for the job. Work progressively from coarse grades to finer grades.
DO NOT go from coarse to fine in one step as it may be difficult to remove swirl marks left by the coarse
grit.
DO NOT apply excessive pressure, let the sander do the work for you. Start the sander and bring the
sanding disc to the work surface evenly and slowly. Move the sander back and forth in overlapping
areas. Remove the sanding disc from the work surface before stopping the sander. Regularly check the
sanding disc for wear, always change if cracked or damaged.
DO NOT allow sander to run in “idle rotation” for an extended period of time, as this will reduce bearing
life.
