 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 sander 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. To remove backing pad disc, use16mm spanner to hold spindle and rotate pad anticlockwise.
5.5. For a full service contact your local Sealey service agent.
5.6. When not in use, disconnect from air supply, clean sander and store in a safe, dry, childproof location.
4. OPERATING INSTRUCTIONS
5. MAINTENANCE

WARNING! Ensure that you read, understand and apply the safety instructions before use.
4.1. Assembly.
4.1.1. Apply appropriate sanding disc to the backing pad. 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 knurled throttle knob on the side of the handle.
4.2. Operating.
The sander is designed to provide a “rotary” or “random orbit” action, see fig.4 for method.
Always use sanding disc with grit 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 change a cracked or damaged pad.
DO NOT allow sander to run “idle” for an extended period of time as this will shorten bearing life.
Slacken, adjust thumbwheel, tighten.
