3. PREPARING SANDER FOR USE
4. OPERATING INSTRUCTIONS
5. MAINTENANCE
LEAD PAINT WARNING!
Paint once contained lead as a traditional ingredient. Contact with the dust from 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 have contained lead in the 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
persons are particularly vulnerable to the effects of lead paint dust: Expectant 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 SSP266).
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) above, and thoroughly clean all areas when
task is complete. Ensure paint waste is disposed of according to local authority regulations. 4.1 Select the appropriate arm (fig 3.1) and push it onto the sander sleeve (2) ensuring the locking
hole clips over locking stud (3).
4.2 Attach the appropriate sanding disc to the arm accordingly.
4.3. Press trigger (4) to start the sander.
4.4. The air flow may be adjusted by turning control
knob (5).
NOTE: The sander is designed for
dry use only. DO NOT use with
water or any other liquids.

3.1. Air Supply
pWARNING! Ensure the air supply is clean and does not exceed 90 psi while operating the drill.
Too high an air pressure and unclean air will cause excessive wear, and may be dangerous, causing
damage and/or personal injury.
3.1.1. Ensure the sander air valve (or trigger) is not depressed 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. Drain the air tank daily. Water in the air line will damage the drill and invalidate your warranty.
3.1.4. Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig 1.
3.1.5. 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.
3.1.6. 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 - Sealey model number AH2R or AH2R/38 - to the drill. A quick
change coupling may then be used to connect the leader hose to the air line recoil hose. See figs. 1 & 2.
