Troubleshooting - GMC GAC1500 Manual Del Usario

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
