4. PREPARATION
4.1. AIR SUPPLY
4.1.1. Ensure tool 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 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.
4.1.3. Drain the air tank daily. Water in the air line will damage the tool.
4.1.4. Clean air inlet filter weekly. Recommended hook-up procedure is shown in 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 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 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.
5. OPERATION
WARNING! Ensure you read, understand and apply safety instructions before use.
Note: Numbers in brackets refer to item numbers in the parts diagram.
5.1. FLUX CHIPPER
5.1.1. Fit the spring (4) onto the rounded end of the chisel (15) before tting the chisel into the barrel sleeve (12).

5.2.2. Fit the needle driver (14) and ensure the spring (18) is located in the needle tube (19).
5.2.3. Ensure the needle holder (17) is tted with needles (16) such that the heads of the needles do not protrude above the surface of
the needle holder.
5.2.4. Fit the needle holder (17) into the needle tube (19), screw the needle tube (19) onto the barrel sleeve (12) and tighten.
5.2.5. To start the tool, depress the throttle lever.
8 DO NOT allow the tool to free run for an extended period of time as this will shorten its life.
6. MAINTENANCE
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.
Note: Numbers in brackets refer to item numbers in the parts diagram.
6.1. To replace the needles (16), unscrew the needle tube (19) from the barrel sleeve (12). Remove the needle holder (17) and replace

WARNING! – Risk of Hand Arm Vibration Injury.
This tool may cause Hand Arm Vibration Syndrome if its use is not managed adequately.
This tool is subject to the vibration testing section of the Machinery Directive 2006/42/EC.
This tool is to be operated in accordance with these instructions.
Measured vibration emission value (a): 8.56 m/s²
Uncertainty value (k): 1.34 m/s²
Please note that the application of the tool to a sole specialist task may produce a different average vibration emission. We recommend that a
specific evaluation of the vibration emission is conducted prior to commencing with a specialist task.
A health and safety assessment by the user (or employer) will need to be carried out to determine the suitable duration of use for each tool.
NB: Stated Vibration Emission values are type-test values and are intended to be typical.
Whilst in use, the actual value will vary considerably from and depend on many factors.
Such factors include; the operator, the task and the inserted tool or consumable.
NB: ensure that the length of leader hoses is sufficient to allow unrestricted use, as this also helps to reduce vibration.
The state of maintenance of the tool itself is also an important factor, a poorly maintained tool will also increase the risk of Hand Arm Vibration
Syndrome.
Health surveillance.
We recommend a programme of health surveillance to detect early symptoms of vibration injury so that management procedures can be modified
accordingly.
Personal protective equipment.
We are not aware of any personal protective equipment (PPE) that provides protection against vibration injury that may result from the
uncontrolled use of this tool. We recommend a sufficient supply of clothing (including gloves) to enable the operator to remain warm and dry and
maintain good blood circulation in fingers etc. Please note that the most effective protection is prevention, please refer to the Correct Use and
Maintenance section in these instructions. Guidance relating to the management of hand arm vibration can be found on the HSC website
www.hse.gov.uk - Hand-Arm Vibration at Work.
