Thank you for purchasing a Sealey product. Manufactured to a high standard, this product will, if used according to these instructions, and properly maintained, give you years of trouble free performance.
IMPORTANT: PLEASE READ THESE INSTRUCTIONS CAREFULLY. NOTE THE SAFE OPERATIONAL REQUIREMENTS, WARNINGS & CAUTIONS. USE THE PRODUCT CORRECTLY AND WITH CARE FOR THE PURPOSE FOR WHICH IT IS INTENDED. FAILURE TO DO SO MAY CAUSE DAMAGE AND/OR PERSONAL INJURY AND WILL INVALIDATE THE WARRANTY. KEEP THESE INSTRUCTIONS SAFE FOR FUTURE USE.
SAFETY
- WARNING! Ensure health & safety, local authority, and general workshop practice regulations are adhered to when using this equipment.
- WARNING! Disconnect from air supply before changing accessories or servicing.
- Maintain the needle scaler in good condition and replace any damaged or worn parts. Use genuine parts only. Unauthorised parts may be dangerous and will invalidate the warranty.
- WARNING! Check correct air pressure is maintained and not exceeded. We recommend 90psi.
- Keep air hose away from heat, oil and sharp edges. Check air hose for wear before each use and ensure that all connections are secure.
- Only use needles which are specifically designed for use with a needle scaler.
- Wear approved safety eye/face shield, ear defenders, and hand protection.
- Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip shoes.
- Keep children and non-essential persons away from the working area.
- DO NOT use the needle scaler for a task it is not designed to perform.
- WARNING! DO NOT use needle scaler if damaged or thought to be faulty. (Contact Sealey service agent).
- DO NOT use needle scaler unless you have been instructed in its use by a qualified person.
- DO NOT carry the needle scaler by the air hose, or yank the hose from the air supply.
- DO NOT operate needle scaler if you are tired or under the influence of alcohol, drugs or intoxicating medication.
- DO NOT carry needle scaler with your hand on the power trigger in order to avoid unintentional starting.
- DO NOT direct air from the air hose at yourself or others.
- When not in use disconnect from air supply and store in a safe, dry, childproof location.
INTRODUCTION
Generation series pistol type scaler suitable for cleaning heavy paint and rust scale from metal surfaces. Removable needle head allows use as a standard air hammer but requires additional chisel set and spring retainer (not included). Features variable speed trigger control. Spring retainer, needle and chisel sets available separately.
SPECIFICATION
- Model No: SA50
- Air Consumption: 4cfm
- Inlet Size: 1/4”BSP
- Noise Power/Pressure: 111/100dB(A)
- No-Load Speed: 4500bpm
- Operating Pressure: 90psi
- Stroke: 43mm
- Vibration/Uncertainty: 13/5.2m/s²
ASSEMBLY
- Screw the scaling head fully onto the body as indicated in fig.1.
- Tighten the 3 grub screws located around the scaling head.
AIR SUPPLY
- Ensure needle scaler trigger is not depressed before connecting to the air supply.
- You will require an air pressure of 90psi, and a minimum air flow of 2.8cfm.
WARNING! Ensure the air supply is clean and does not exceed 90psi while
operating the needle scaler. 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. Drain the air tank daily. Water in the air line
will damage the needle scaler. Clean air inlet filter weekly. Recommended
hook-up procedure is shown in fig.2.
- 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.
- Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are secure.
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. A quick change coupling may then be used to connect the leader hose to the air line recoil hose. See fig.2 & 3.
OPERATION
- WARNING! Ensure you read, understand and apply safety instructions before use.
- Connect the needle scaler to the air hose as in section 4.
- To start the scaler, depress the trigger. DO NOT allow the needle scaler to free run for an extended period of time as this will shorten its life.
- Air flow may also be regulated by the air flow valve at the bottom of the handle (fig.1A).
MAINTENANCE
WARNING! Disconnect needle scaler 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. To
replace the needles, remove the large cir-clip from the back opening of the
main sleeve and loosen the three grub screws. Take hold of the sleeve and
press the needles firmly onto a hard surface to ease the plastic retainer out
of the sleeve. Remove the hammer followed by the needle supporter, needles and
the spring. Remove the old needles from the needle supporter and replace them
with a new set. Reassemble the scaling head in the reverse order to that
described above. Refer to the parts diagram. Screw the reassembled scaling
head back onto the pistol body. Lubricate the needle scaler daily with a few
drops of Sealey air tool oil dripped into the air inlet. Clean the needle
scaler after use. Loss of power or erratic action may be due to the following:
- 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 4.
- 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 SAE No 10 oil and paraffin. Allow to dry before use. For a full service contact your local Sealey service agent. 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): 13 m/s² Uncertainty
value (k): 5.2 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.
