4. AIR SUPPLY
4.1.
Recommended hook-up procedure is shown in fig.1.
4.2.
Ensure the grinder air valve (or throttle) is in the "off" position before connecting to the air supply.
4.3.
You will require an air pressure of 90psi and an air flow according to the specification above.
WARNING! Ensure the air supply is clean and does not exceed 90psi while operating the grinder.
‰
4.4.
Too high an air pressure and unclean air will cause excessive wear, and may be dangerous, causing damage and/or personal
injury.
4.5.
Drain the air tank daily. Water in the air line will damage the grinder and invalidate your warranty.
4.6.
Clean air inlet filter weekly.
4.7.
Line pressure should be increased to compensate for unusually long air hoses (over 8 metres).
4.8.
The minimum hose diameter should be 1/4" I.D. and fittings must have the same inside dimensions.
4.9.
Keep hose away from heat, oil and sharp edges. Check hoses for wear, and make certain that all connections are secure.
4.10.
Couplings
4.10.1.
Vibration may cause failure if a quick change coupling is connected directly to the air grinder. To overcome this, connect a leader hose
- Sealey model number AH2R or AH2R/38 - 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.

5. OPERATION
WARNING! Ensure that you read, understand and apply the safety instructions before use.
‰
5.1.
Assembly: - The SA151.V2 comes with a handle, a spanner and a hex key.
5.1.1.
The handle screws into the left or right-hand side of the head.
5.1.2.
Remove the disc locking hex bolt from the grinder spindle. Use the spanner supplied to hold the lower flange and loosen/tighten the
hex bolt.
5.1.3.
Fit the grinding disc (not supplied) to the spindle in between the two flanges and secure with the hex bolt. Use only discs with speed
ratings equal to, or higher than the speed rating of the grinder.
5.1.4.
Connect air supply to grinder. Push safety button (adjacent to trigger) with thumb and squeeze the control valve lever to check that the
grinder is working correctly.
5.2.
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 free-run the grinder off the workpiece for extended periods as this will shorten the life of the bearings.

6.
MAINTENANCE
WARNING! Disconnect grinder from air supply before changing disc, servicing or performing maintenance.
‰
6.1.
Replace or repair damaged parts. Use genuine parts only. Unauthorised parts may be dangerous and will invalidate the warranty.
6.2.
Lubricate the grinder daily with a few drops of good grade air tool oil, such as Sealey ATO1000S, dripped into the air inlet before
use or dispensed automatically through an air system oiler, such as Sealey model SA2001/L.
6.3.
Clean the grinder after use and change the disc when worn or damaged.
6.4.
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.
