WARNING: Maintenance not covered by this manual MUST be carried out by an authorised GMC technician.
Attempting such maintenance or repairs will void the guarantee.
WARNING: Some of the maintenance procedures described in this manual require some general technical
skills and expertise. This compressor MUST ONLY be serviced by people with the necessary skill level. If in
doubt, have the machine serviced at an authorised GMC service centre.
Cleaning
•
Keep your tool clean at all times. Dirt and dust will cause internal parts to wear quickly, and shorten the
machine's service life. Clean the body of your machine with a soft brush, or dry cloth. If available, use
clean, dry, compressed air to blow through the ventilation holes
•
Use a mild detergent and a damp cloth to clean parts contaminated with oil. Rinse with fresh water and
dry thoroughly
•
Keep all electric and electronic components dry at all times
Depressurising the air tank
•
If it is necessary to release residual air pressure from the air tank, disconnect the compressor from the
mains power supply and pull the ring in the centre of the Pressure Release Valve (8) outwards
•
Residual air will escape from the valve until the ring is released, or all air pressure is released
Draining
•
During use, atmospheric moisture will condense in the air storage tank. The tank should be drained of
moisture on a regular basis to avoid corrosion damage
•
To drain moisture, open the Drain Cock (13), located on the underside of the tank, approximately 3 turns
anti-clockwise
•
Allow all moisture to drain and retighten plug
Air filter maintenance
WARNING: Never run this compressor without the air filter element fitted, as this would lead to rapid wear of
internal components, causing permanent internal damage and shorten the service life of this compressor.
1.
Detach the Air Filter (15) from the Cylinder Head (4), by turning it anticlockwise
2.
Remove the wing nut from the top of the Air Filter assembly, and remove the air filter element from the
inside of the assembly
3.
Wash the filter element thoroughly in a solution of warm water with non-foamy household detergent, or
clean with a specialised non-flammable solvent
WARNING: DO NOT use petrol or other flammable solvents to clean the filter element, as this could lead to
fire or explosion.
4.
Dry the filter element thoroughly
WARNING: DO NOT wring out the element, as this would damage the sponge material.
WARNING: NEVER install a wet filter element, as water in the air intake will lead to permanent motor damage.
5.
Immerse the dried filter element in clean motor oil, or alternatively, apply specialised air filter oil to the
filter element. Gently squeeze (but DO NOT wring out) to remove excess oil.
Note: If the filter element is installed soaked in excessive amounts of oil, the motor will produce large
amounts of smoke after being started.
6.
Reinstall the Air Filter to the Cylinder Head. Ensuring that the Air Filter is securely tightened into the
intake port.
Motor oil maintenance
WARNING: Motor oil is a major pollutant and MUST NOT be allowed to enter the environment. Dispose of
according to local laws and regulations.
WARNING: Used motor oil can cause dermatitis and other skin disorders, including skin cancer, if repeatedly
left in contact with skin for prolonged periods of time. Wear suitable gloves and thoroughly wash your hands
and other exposed skin with soap and water as soon as possible after handling used oil.
Note: Motor oil is best drained when the compressor is still warm. If the compressor is cool, start and let it run
for a few minutes, before changing the oil. This will lead to more rapid and complete draining.
WARNING: Take special care not to touch hot motor parts.
Note: Motor oil is extracted and poured through the Crankcase Breather (3) hole
1.
Ensure the On/Off Switch (6) is in the 'OFF' position
2.
Remove the Crankcase Breather from the crankcase to reveal the Crankcase Breather hole
3.
Place an oil suction gun (or syphon pump) receiver into the Motor Oil Fill Point. Operate the oil removal
tool to extract the oil
4.
Refer to 'Filling with motor oil' for information on refilling
Storage
WARNING: Ensure the On/Off Switch (6) is in the 'Off' position, the power cord is disconnected from the
mains, and the air Reservoir Tank (1) is depressurised, before transporting or storing the air compressor.
Transporting the air compressor
•
This air compressor provides a Transport Handle (9) located at the front. Due to its weight and size, the
device should always be moved using the transportation handle and wheels.
Storing the compressor
•
Store carefully in a secure, dry place out of the reach of children
Preparation for long-term storage
•
Whenever the machine is out of use for an extended period of time, proceed as follows:
•
Give the unit an overall cleaning and a thorough check
•
Clean the air filter as described in 'Air filter maintenance'
•
Change the motor oil as described in 'Motor oil maintenance'
•
Protect all metal parts from corrosion by coating them with oil or a machinery preservative
Disposal
Always adhere to national regulations when disposing of power tools that are no longer functional and are
not viable for repair.
•
Do not dispose of power tools, or other waste electrical and electronic equipment, with household waste
•
Contact your local waste disposal authority for information on the proper way to dispose of tools
•
Oil must not be disposed of with household waste. Improper disposal may be regarded a criminal offence
in your country. Contact your local authority or dealer for correct disposal procedures for oil
