3. PREPARING SANDER FOR USE
3.1. Air Supply
3.1.1. Ensure the air valve (or throttle) is in the "off" position before connecting to the air supply.
3.1.2. You will require an air pressure and an air flow (cfm) according to the specification listed above.
3.1.3. WARNING! Ensure that the air supply is clean and does not exceed the pressure quoted while
operating the sander. Too high an air pressure and/or unclean air will shorten the life of the sander due to
excessive wear and may be dangerous causing damage and/or personal injury.
3.1.4. Drain the compressor air tank daily. Water in the air line will damage the sander.
3.1.5. Clean the compressor air inlet filter weekly. Recommended hook-up 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 bore.
3.1.7. Keep hose away from heat, oil and sharp edges. Check hoses for wear and make certain that all
connections are secure.
3.2. Couplings
Vibration may cause failure if a quick fit coupling is connected directly to the air tool.
To overcome this, connect a leader hose to the tool. A quick fit coupling may then be used to connect the
leader hose to the air line recoil hose. See figs. 1 & 2.

3.3. Dust Collection
3.3.1. Models MAT150AS & MAT110AS.
The dust outlet tube of the sander must be connected to a dust-free system in accordance with COSHH,
and any other regulations that may apply to the work area. For information on dust-free systems, contact
your local Sealey dealer.
3.3.2. Model MAT150SC only
This model has a dust bag included. Attach the dust extraction pipe to the machine outlet and secure it
with the worm drive clip provided. Insert the other end into the small opening at the bag head. Push the
tube half way into the bag. Secure with the ties. To empty the bag, wear appropriate dust mask, etc., open
the velcro end and empty contents according to disposal regulations. Do not place any liner in the bag as
this will inhibit the air flow.
4. OPERATING INSTRUCTIONS
4.1. Attach a suitable sanding material to the velcro backing disc / pad.
4.2. Connect the sander to the air supply and to a dust free system if required (MAT150AS & MAT110AS).
Press the control valve (ON/OFF) lever and check that the unit is working correctly. Some models will have
an air flow control knob. Turn the knob to increase or decrease the air flow.
Note: The sander is designed for dry use only. DO NOT use with water or any other liquids.
5. MAINTENANCE
WARNING!Disconnect sander from air supply before changing accessories, servicing or performing
maintenance.Replace or repair damaged parts. Use recommended parts only.
Unauthorised parts may be dangerous and will invalidate the warranty.
5.1. DO NOT oil the sander, or connect to an air supply which incorporates an oiler. Oiling will result in damage
to teflon surfaces within the sander.
5.2 Clean the sander after use and change pads when required.
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 Section 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 10 oil and kerosene. Allow to dry before use.
c) If you continue to experience problems, contact your local Sealey service agent.

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.
