5. OPERATION
fig.2
5.1. Air Supply
Recommended hook-up procedure is shown in fig.2.
5.1.1. Ensure the Air Die Grinder is in the "OFF" position (fig.3) before connecting to the air supply.
5.1.2. 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 90psi while operating the tool. 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.
5.1.3. Drain the air tank daily. Water in the air line will damage the tool.
5.1.4. Clean the air inlet filter weekly.
5.1.5. 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.
5.1.6. Keep the hose away from heat, oil and sharp edges. Check the hose for wear, and make certain that all connections are secure.
WARNING! Ensure that you read, understand and apply the safety instructions in Section 1.

"OFF"/"ON" Knurled Section
5.2. Grinding
WARNING! Disconnect from the air supply before changing the grinding wheel bits.
5.2.1. Choose the appropriate grinding wheel bit and check it is not flawed. Flawed grinding wheel bits must not be used.
5.2.2. Use the supplied chuck spanners to loosen the collet locking collar. Insert the bit full depth and lock in position with the spanners.
5.2.3. Ensure that the workpiece is properly secured and, if necessary, marked out.
5.2.4. To start, hold the grinder firmly, away from the workpiece and twist the knurled section in fig.3 to the "ON" position.
5.2.5. The bit must be running at its maximum speed before attempting to grind the workpiece.
5.2.6. Always hold the die grinder firmly (fig.4) and ease the grinding wheel against the workpiece with controlled progression. Avoid
subjecting the grinding wheel to jerky or excessive forces; let the grinding wheel do the work.
DO NOT allow the air tool to run free for any length of time, as this will shorten the life of wearing parts.

6. MAINTENANCE
WARNING! Disconnect the die grinder from the air supply before changing the bits, servicing or performing maintenance. Replace
damaged parts. Use genuine parts only. Unauthorised parts may be dangerous and will invalidate the warranty.
6.1. Unless the air supply system includes an oiler, lubricate the air grinder daily with a few drops of air tool oil, dripped into the in line
oiler before use. [Item 4 in parts list or Sealey part no’s. ATO500S (500ml) or ATO1000S (1 Litre)].
6.2. 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 line. Incorrect size or type of hose connectors. To remedy, check
the air supply and follow instructions in Section 5.
b) Grit or gum deposits in the grinding wheel bit 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 grinder 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.
6.3. For a full service, contact your local Sealey service agent.
6.4. When not in use, disconnect from the air supply, clean the grinder with a brush or dry cloth. Wipe clean the sheath with a moist cloth
and mild detergent. Store all in a safe, dry, childproof location.
