LEAD PAINT WARNING!
Paint once contained lead as a traditional ingredient. Contact with the toxic dust from the removal of
such paint 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 work 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 Respirators (Our ref SSP1604, SSP1699)
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. Seal paint waste in bags or containers for disposal according to local regulations.

3. PREPARING SANDER FOR USE
3.1.
Air Supply
3.1.1. Ensure the air valve (or throttle) is in the "off" position before connecting to the air supply.
3.1.2. You will require an air pressure and an air flow (cfm) according to the specification listed above.
3.1.3. WARNING! Ensure that the air supply is clean and does not exceed the pressure quoted while
operating the sander. Too high an air pressure and/or unclean air will shorten the life of the sander due to
excessive wear and may be dangerous causing damage and/or personal injury.
3.1.4. Drain the compressor air tank daily. Water in the air line will damage the sander.
3.1.5. Clean the compressor air inlet filter weekly. Recommended hook-up 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 bore.
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 fit coupling is connected directly to the air tool.
To overcome this, connect a leader hose to the tool. A quick fit coupling may then be used to connect the
leader hose to the air line recoil hose. See figs. 1 & 2.

3.3.
Dust Collection
3.3.1. All models except MA90SC & MA150SC
The dust outlet tube of the sander must be connected to a dust-free system in accordance with COSHH,
and any other regulations that may apply to the work area. For information on dust-free systems, contact
your local Sealey dealer.
3.3.2. Models MA90SC & MA150SC only
These models have a dust bag included. Attach the dust extraction pipe to the machine outlet and insert
into the small opening at the bag head. Push the tube half way into the bag.
To empty the bag, wear appropriate dust mask, etc., open the velcro end and empty contents
according to disposal regulations. Do not place any liner in the bag as this will inhibit the air flow.
4. OPERATING INSTRUCTIONS
4.1.
Attach the correctly rated pad to the sander. Round pads screw into the under side of the sander head
and rectangular pads are held under the clamps located at each end of the sander.
4.2.
Model MA90SC has an alternative metal plate which may be placed between the sanding pad and the
soft sanding plate for additional pressure.
4.3.
Connect the sander to the air supply and the dust free system (not MA90SC or MA150SC).
Press the control valve (ON/OFF) lever and check that the unit is working correctly. Some models will
have an air flow control knob. Turn the knob to increase or decrease the air flow.
Note: The sander is designed for dry use only. DO NOT use with water or any other liquids.
5. MAINTENANCE
WARNING! Disconnect sander from air supply before changing accessories, servicing or performing
maintenance. Replace or repair damaged parts. Use recommended parts only.
Unauthorised parts may be dangerous and will invalidate the warranty.
5.1. DO NOT oil the sander, or connect to an air supply which incorporates an oiler. Oiling will result in
damage to teflon surfaces within the sander.
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 tool 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 tool out with gum solvent oil or an equal mixture of SAE 10 oil and kerosene.
Allow to dry before use.
c) If you continue to experience problems, 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 and store in a safe, dry, childproof location.
