INTRODUCTION & SPECIFICATIONS
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.
p
WARNING!
Ensure the air supply is clean and does not exceed 90 psi while operating the sander.
Too high an air pressure and 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 fig 1 & 2.

WARNING!
Disconnect sander from air supply before changing accessories, servicing or performing
maintenance. Replace or repair damaged parts.
Use genuine parts only. Non-authorised parts may be
dangerous and will invalidate the warranty.
5.1.
Lubricate the air sander 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.
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 chapter 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 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 sander and store in a safe, dry, childproof location.

5. 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
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 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 in sealed bags or containers.
p
WARNING! Ensure you read, understand and apply safety
instructions fore use.
4.1.
Assembly.
4.1.1. Apply appropriate sanding pad to the backing disc. Use only pads with speed
ratings equal to or higher than the speed rating of the sander. DO NOT use cloth
backed sanding pads.
4.1.2. Connect air supply to sander and press the control valve lever and check
that the sander is working correctly.
4.1.3. The air flow may be regulated by turning the control knob on the side of the handle.
4.2.
Operating.
The sander is designed to provide two sanding actions, rotary and random orbit. These actions are controlled
by the spindle lock position (fig 3). For a random orbit, turn the spindle lock so that the flat (A) faces the drive
spindle (B). For rotary action turn the spindle lock so the flat is away from the drive spindle.
Always use grit pad 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 coarser grit.
DO NOT apply excessive pressure, let the sander do the work for you. Start the sander and bring the sanding
disc to the 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 pad for wear, always
changed a cracked or damaged pad.
DO NOT allow sander to run in idle rotation for an extended period of time as this will shorten life of bearings.
