4.3.
COUPLINGS
Vibration may cause failure if a quick change coupling is connected directly to the needle scaler. To overcome this, connect a leader
hose to the needle scaler (Sealey ref: AH2R or AH2R/38). A quick change coupling may then be used to connect the leader hose to
the air line recoil hose (fig.2 & fig.3).
5. OPERATION
WARNING! Ensure you read, understand and apply Section 1 safety instructions.
5.1.
Connect the needle scaler to the air supply as described in Section 3.
5.2.
To start the scaler, depress the trigger.
8
DO NOT
allow the needle scaler to free run for an extended period of time as this will shorten its life.
6. MAINTENANCE
NOTE:
Numbers in brackets refer to the parts list and diagram.
WARNING!
Disconnect needle scaler from air supply before servicing or performing maintenance. Replace or repair damaged
parts.
Use genuine parts only. Unauthorised parts may be dangerous and will invalidate the warranty.
Numbers refer to attached Parts List.
6.1.
To replace the needles, unscrew the body from the scaling head (refer fig.1).
6.2.
Unscrew the Front Cover (23) from the Body (17) and remove the old Needles (19) and Needle Holder (20). Remove the old
needles from the needle holder and replace them with a new set of needles. Reassemble the scaling head in the reverse
order of that described above. Screw the reassembled scaling head back onto the pistol body.
6.3.
Lubricate the needle scaler daily with a few drops of Sealey air tool oil dripped into the air inlet.
6.4.
Clean the needle scaler after use.
6.5.
Loss of power or erratic action may be due to the following:
6.6.
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 Section 3.
6.7.
b)
Grit or gum deposits in the needle scaler may also reduce performance. Flush the needle scaler out with gum solvent oil or an
equal mixture of SAE10 oil and paraffin. Allow to dry before use.
6.8.
For a full service contact your local Sealey service agent.
6.9.
When not in use, disconnect from air supply, clean needle scaler and store in a safe, dry, childproof location.
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): 4.9m/s²
Uncertainty value (k):2.45m/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 HSE website
