Maintenance - General International AC1105 Operating Manual

To install an air hose, equipped with a 1/4" male
coupler:
1. Pull back on Air Chuck outer sleeve to allow
coupler to be fully inserted into Air Chuck.
2. Insert coupler into Air Chuck.
3. Release outer sleeve of Air Chuck.
4. Verify that air hose is securely connected to Air
Chuck by pulling lightly on air hose.
Adjusting the Air Pressure
Your Air Compressor is supplied with an Air
Pressure Regulator. This Regulator adjusts the air
pressure.
To increase air pressure, turn Air Regulator
clockwise.
To decrease air pressure, turn Air Regulator
counterclockwise.
Cold Weather Starting
Temperatures below freezing (32°F) cause the
metal parts of your Air Compressor to contract and
that makes starting more difficult. To assist the Air
Compressor in starting in cold weather, follow
these tips:
1. Try to keep Air Compressor stored in
temperatures above 32° fahrenheit.
2. Open the Air Tank Drain Valve and release all air
pressure from the Air Tank before attempting to
start in cold weather. (After air is released from
Air Tank, close Drain Valve.)
3. Plug Air Compressor directly into a 120 volt
electrical outlet. Do not use an extension cord
when starting your Air Compressor in cold
weather.

MAINTENANCE

Daily (or before each use)
1. Check oil level
2. Drain condensation from the air tank.
3. Check for any unusual noise or vibration.
4. Be sure all nuts and bolts are tight.
Weekly
1. Clean breather hole on Oil Breather Cap.
Monthly
1. Inspect air system for leaks by applying soapy
water to all joints. Tighten these joints if leaks
are discovered.
6 Months (or after 250 hours of operation -
whichever comes first)
1. Change Air Compressor Oil.
Note: Change oil more often if Air Compressor is
used near paint spraying operations or in dusty
environments.
Checking the Air Compressor Oil
1. Place Air Compressor on level surface. The oil
level should be at the red dot on the Oil Sight
Glass.
2. If oil level is low, remove Oil Breather Cap and
add enough oil to bring the oil level to the red
dot on the Oil Sight Glass.
3. Replace Oil Breather Cap before starting
compressor.
Changing the Air Compressor Oil
Note: This compressor uses only SAE 5W-30 oil.
1. Remove the Oil Sight Glass by turning counter
clockwise with wrench.
Note: Oil will begin to drain as Oil Sight Glass is
loosened. Place a funnel and oil pan under the Oil
Sight Glass BEFORE loosening.
2. Once Oil Sight Glass is removed, tilt Air
Compressor backwards to allow all of the oil to
drain out of the crankcase.
3. Once oil is drained, replace Oil Sight Glass
and securely tighten in place with a wrench. Be
careful not to overtighten the Oil Sight Glass, as
this could damage the rubber seal.
4. Place Air Compressor on level surface.
5. Remove the Oil Breather Cap.
6. Slowly pour the oil into the oil fill hole, until the
oil level rises to the center of the red dot on the
Oil Sight Glass.
7. Install the Oil Breather Cap into the oil fill hole.
Firmly hand tighten the Oil Breather Cap by
turning clockwise.
Always inspect the tool before use, and make sure it
is in good working condition. Make sure all air vents
are clear, (use compressed air to clean the machine
where possible). Check the power cable to make
sure it is intact and free from cracks, bare wires etc.
Avoid using solvents when cleaning plastic parts,
most plastics are susceptible to damage from the
various types of commercial solvents.
