PREPARING SCREWDRIVER
3.1.
Air Supply
3.1.1. Ensure screwdriver air valve (or trigger) is in "off" position before connecting to air supply.
3.1.2. You will require an air pressure of 90psi, and an air flow according to specification.
3.1.3. p WARNING! Ensure the air supply is clean and does not exceed 90 psi while operating the
screwdriver. 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 screwdriver.
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 hose 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
screwdriver. To overcome this, connect a leader hose to the screwdriver. A quick change
coupling may then be used to connect the leader hose to the air line recoil hose. See fig 1 & 2.

4. OPERATING INSTRUCTIONS
WARNING! Ensure you read, understand and apply safety instructions before use.
p
4.1.
Push driver bit into self locking chuck. To release bit, push chuck collar forward and pull bit out.
4.2.
Connect the screwdriver to the air hose as in chapter 3.
4.3.
The screwdriver direction is changed by switching the reverse lever behind the trigger. Check
that the screwdriver is set to operate in the required direction.
4.4
Depress the trigger to operate the screwdriver accordingly.
DO NOT allow screwdriver to free run for an extended period of time as this will shorten its life.

4.5.
To change the torque.
4.5.1.
Remove clutch housing (fig 3.1.) from main motor housing (4) by turning hand grip (2)
clock-wise, to expose the cam assembly (3). Note: the clutch housing is packed with grease.
4.5.2.
Place a wrench on nut (X) and turn to adjust torque as follows:
INCREASE TORQUE .....by tightening nut.
DECREASE TORQUE.....by loosening nut.
4.5.3.
Re-pack with heavy grease and re-assemble.
5. MAINTENANCE
WARNING! Disconnect screwdriver from air supply before changing accessories, servicing or
performing maintenance. Replace or repair damaged parts. Use genuine parts only. Non-
p
authorised parts may be dangerous and will invalidate the warranty.
5.1.
Lubricate the air screwdriver daily with a few drops of Sealey air tool oil dripped into the air
inlet to prolong its life.
5.2.
Clean the screwdriver after use.
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 screwdriver 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 screwdriver out with gum solvent oil or an equal mixture of SAE No 10 oil and
paraffin. Allow to dry before use.
5.4.
For a full service contact your local Sealey service agent.
5.5.
When not in use, disconnect from air supply, clean screwdriver and store in a safe, dry,
childproof location.
