INSTRUCTIONS FOR:
AIR KNIFE
MODEL No: WK025
Original Language Version WK025 Issue: 2 - 11/11/09

3.1. Air Supply
Recommended hook-up procedure is shown in fig 1.
3.1.1. Ensure tool air valve (or trigger) is in "Off" position before connecting to the air supply.
3.1.2. You will require an air pressure of 90psi, and an air flow according to specification.
3.1.3. 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.
3.1.4. Drain the air tank daily. Water in the air line will damage the tool.
3.1.5. Clean air inlet filter weekly.
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 tool.
To overcome this, connect a leader hose to the tool. A quick change coupling may
then be used to connect the leader hose to the air line recoil hose. See fig 1 & 2.

 WARNING! Disconnect tool 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.
5.1. If the air supply does not have an oiler, lubricate the air tool daily with a few drops of Sealey
air tool oil dripped into the air inlet to prolong its life.
5.2. Clean the tool 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 tool 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
tool 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.

4.2.2. To start the tool, hold firmly and push the trigger locking lever forward whilst depressing trigger.
4.2.3. The blade must be oscillating at its maximum speed before attempting to cut.
4.2.4. Slowly and smoothly bring the blade toward the workpiece (avoid jerky movements).
4.2.5. Exert adequate pressure on the tool to allow cutting according to the type and size of the
material you are working with. Avoid subjecting blade to excessive strain, always hold tool
firmly and ease blade against workpiece. Maintain a controlled progression.
DO NOT allow tool to free run for an extended period of time as this will shorten its life.
