4. AIR SUPPLY
4.1.
Air Supply. (Recommended hook-up procedure is shown in fig.1.)
4.1.1.
Ensure sander air valve (or 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 specification.
‰
WARNING! Ensure the air supply is clean and does not exceed 90 psi while operating the wrench. 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 compressor air tank daily. Water in the air line will damage the wrench.
4.1.4.
Clean compressor air inlet filter weekly.
fig 1
4.1.5.
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.
4.1.6.
Keep the hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are secure.
4.2.
Couplings. Vibration may cause failure if a quick change coupling is connected directly to the wrench. 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 & fig.2.
5. OPERATION
‰
WARNING! Ensure you read, understand and apply safety instructions before use.
5.1.
Assembly.
5.1.1.
Your SA18/S comes with one handle, two spanners and a backing disc.
5.1.2.
The handle may be screwed into the left or right-hand side of the head.
5.1.3.
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.
5.1.4.
Remove the disc locking nut from the sander hub. Screw the backing disc onto the central spindle and secure with the locking nut. Use
spanners supplied to hold the hub and tighten the lock nut.
5.1.5.
Connect air supply to sander and press the control valve lever to check that the sander is working correctly.
5.2.
Operating.
5.2.1.
The air flow may be regulated by turning the control valve screw on top of the handle.
5.2.2.
Always use grit pad appropriate for the job. Work progressively from coarse grades to finer grades.
8
DO NOT go from coarse to fine in one step as it may be difficult to remove swirl marks left by the coarser grit.
8
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. 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.
8
DO NOT allow sander to run in "idle rotation" for an extended period of time as this will shorten life of bearings.
6. MAINTENANCE
‰
WARNING! Disconnect sander from air supply before changing accessories, servicing or performing maintenance. Replace or repair
damaged parts. Use genuine parts only. Unauthorised 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 ATO1000, 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 4.
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.
6.4.
For a full service contact your local Sealey stockist.
6.5.
When not in use, disconnect from air supply, clean sander and store in a safe, dry, childproof location.
