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.
- User must determine potential hazard relating to age of paint to be removed (modern paints do not have lead content).
- 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.
- We recommend personal protection by using the following safety items: Paint Spray Respirator (SSP1699), Hooded Coverall (SSP267), Latex Gloves (SSP24).
- Take adequate measures to contain the paint dust, flakes and scrapings.
- Continue to wear safety equipment and thoroughly clean all areas when task is complete. Ensure paint waste is disposed of in sealed bags or containers.

PREPARING TOOL FOR USE
4.1. AIR SUPPLY
4.1.1. Ensure the sander trigger is in the “Off” position before connecting to
the air supply.
4.1.2. You will require an air pressure of 90psi, and an air flow according to
the specifications.
‰ WARNING! 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.
4.1.3. Drain the air tank daily. Water in the air line will damage the sander
and will invalidate your warranty.
4.1.4. Clean air inlet filter weekly. Recommended hook-up procedure is shown
in fig.1.
4.1.5. Line pressure should be increased to compensate for unusually long air
hoses (over 8 metres).
4.1.6. The minimum hose diameter should be 1/4” I.D. and fittings must have
the same inside dimensions. Keep hose away from heat, oil and sharp edges.
Check hoses for wear and make certain that all connections are secure.
4.2. COUPLING
4.2.1. 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.
OPERATION
‰ WARNING! Ensure you read, understand and apply the safety instructions
in Section 1 before use.
5.1. ASSEMBLY
5.1.1. Screw the backing pad into the sander spindle, then tighten with
supplied spanner (fig.3B). Apply the sanding disc, use only discs with speed
ratings equal to or higher than the speed rating of the sander.
x DO NOT use cloth backed sanding discs.
5.1.2. Connect air supply to sander and press the trigger (fig.3C) to check
that the sander is working correctly.
5.2. OPERATING
5.2.1. The sander is designed to provide a combined “rotary” and “random
orbit” action.
5.2.2. The sander speed can be changed by switching the thumb control on the
side of the sander (fig.3A).
5.2.3. Operate the sander by depressing the trigger (fig.3C).
5.2.4. Always use a grit appropriate for the job. Work progressively from
coarse grades to finer grades.
x DO NOT go from coarse to fine in one step as it may be difficult to remove
swirl marks left by the coarse grit.
x 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.
5.2.5. 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.
x DO NOT allow sander to run in “idle rotation” for an extended period of time
as this will reduce bearing life.
MAINTENANCE
‰ WARNING! Disconnect sander from air supply before changing accessories,
servicing or performing maintenance. Replace or repair damaged parts. Use
genuine parts only. Unauthorized parts may be dangerous and will invalidate
the warranty.
6.1. 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.
6.2. Clean the sander after use and change pads when required.
6.3. 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.
6.4. For a full service contact your local Sealey service agent.
6.5. When not in use, disconnect from air supply, clean sander and store in a
safe, dry, childproof location.
