INTRODUCTION & SPECIFICATION
3.1.
Air Supply
Recommended hook-up is shown in fig 1.
3.1.1. Ensure that the grinder 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.
p
WARNING!
Ensure the air supply is clean and does not exceed 90 psi while operating the grinder.
Too high an air pressure and/or unclean air will cause 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 grinder and invalidate your warranty.
3.1.5. Clean air inlet filter weekly.
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 grinder. To prevent this, connect
a leader hose to the grinder. A quick change coupling may then be used to connect the leader hose to the air line
recoil hose. See figs. 1 & 2.
p
WARNING!
Disconnect the grinder from air supply before changing the disc, 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.
Lubricate the grinder daily with a few drops of good grade air tool oil, such as Sealey ATO/500 or
ATO1000, dripped into the air inlet before use or dispensed automatically through an air system oiler, such
as Sealey model SA100L.
5.2. Clean the grinder after use and change the disc when worn or damaged.
5.3. Loss of power or erratic action may be due to the following:
a)
Excessive drain on the air supply. Moisture or restriction in the air line. 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 grinder may also reduce performance. Flush the grinder with gum solvent
oil or an equal mixture of SAE No 10 oil and kerosene. Allow to dry before use.
If you continue to experience problems, contact your local Sealey service agent.
5.4.
When not in use, disconnect from air supply, clean grinder and store in a safe, dry, childproof location.

MAINTENANCE
1.2.
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
grinder 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 people 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 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 work is complete.
Ensure that paint waste is disposed of in sealed bags or containers according to local regulations.

WARNING! Ensure that you read, understand and apply the safety instructions before use.
4.1.
Assembly
4.1.1. The SA16 comes with a handle, one spanner and a hex key.
4.1.2. The handle screws into the left side of the head.
4.1.3. Remove the disc locking flange clamp screw from the spindle. Use the spanner and hex key supplied to
hold the spindle and loosen/tighten the lock nut.
4.1.4. Fit the grinding disc to the spindle and retain with the flange nut. Use only discs with speed ratings equal
to, or higher than, the speed rating of the grinder.
4.1.5. Connect air supply to grinder. Push safety lever with thumb and squeeze the throttle lever to check that
the grinder is working correctly.

WARNING!
DO NOT USE DISCS THAT ARE DAMAGED, OR SUSPECTED OF DAMAGE.
Before using a grinding disc ensure there are no fissures or cracks. Once mounted on the grinder test
the disc before use by facing the grinder in a safe direction (pointing away from yourself, others and
vulnerable items) and operate for a short time.
s
DANGER!
Use of damaged discs may cause damage and/or personal injury.
Grinding discs used in association with this machine shall be of an adequate speed rating and
suitable for the job in hand. The discs shall be made in accordance with BS ISO 525.
Only persons holding a grinding wheel certificate are authorised to change grinding discs.
4.2.
Operating
DO NOT
apply excessive pressure, let the grinder do the work for you. Start the grinder and bring the disc
to the the work surface evenly and slowly. Move the grinder back and forth in overlapping areas.
Remove the grinding disc from the work surface before stopping the grinder. Regularly check the
condition of the disc and always change if worn, cracked or otherwise damaged.
DO NOT
run the grinder off the workpiece for extended periods as this will shorten the life of the bearings.
