INSTALLING AIR FILTERS

See figure 5.

Attach one air filter to the cylinder cover on each side. Screw in a 
clockwise direction to fasten securely.

CHECKING/ADDING OIL

See figure 6.

 WARNING

To avoid damage to the compressor, add oil before starting and 
check oil level before each use.

Always check the oil when the unit is sitting on a level surface and 
before first use.

1. 

There is a red dot in the centre of the sight glass.

2.  An oil level at the top of the red dot indicates oil is at maximum 

level.

3.  An oil level at or below the bottom of the red dot indicates oil is 

below desired level, and oil should be added.

To add oil:

1. 

Unscrew the cap of oil fill hole.

2.  Using a funnel, carefully pour oil into the oil fill hole. Fill only with 

SAE-30 oil.

NOTE:

 Avoid using too much oil. Ensure that the level of the oil 

does not exceed the top of the red dot at sight glass.

3.  Tighten the cap securely into the oil fill hole.

Replace the oil after the first 10 hours of operation and every 50 hours 
following the first oil change. Refer to the Replacing oil section for 
details.

OPERATION

 DANGER

Do not disassemble check valve, tank drain valves or safety relief 
valve with air in tank — bleed tank.

 WARNING

Always wear eye protection with side shields. Failure to do so could 
result in objects being thrown into your eyes resulting in possible 
serious injury.

 WARNING

Do not attach any tools to the open end of the hose until start-up 
has been completed.

 CAUTION

Do not use in an environment that is dusty or otherwise 
contaminated. Using the air compressor in this type of environment 
may cause damage to the unit.

TRANSPORTING THE AIR COMPRESSOR

See figure 7a.

The air compressor should be moved as instructed. This will help 

you avoid damaging the wheel or the air compressor by rolling it over 
items in its path.

Ensure the air compressor is unplugged the power cord is secured 
from free movement.

To move the air compressor:

1. 

Grasp the front handle firmly with two hands.

2.  Lift the air compressor toward you. Make sure the compressor is 

balanced on the wheels.

3.  Push the unit along to the desired location.

4.  Lower the air compressor until it sits securely on a flat surface.

To transport the air compressor up or down stairs:

See figure 7b.

1.  Grasp the front handle and rear handle firmly. Lift the unit into a 

safe and comfortable carrying position.

NOTE:

 Use good lifting techniques and get help if needed.

2.  With proper footing and balance, carry the unit one step at a time.

3.  Use care in transporting the unit down or up stairs to avoid 

damage to the stairs, damage to unit and personal injury. Pay 
extra attention to the drain valve which is under the tank during 
transportation, to avoid any damage.

4.  Lower the air compressor until it sits securely on a flat surface.

ATTACHING/DISCONNECTING AIR HOSE

See figure 8.

NOTE:

 For operation using pressures above 7 bar, 

(102 psi) delivery hoses should be fitted with a safety cord, e.g., wire 
rope.

1. 

Make sure the air compressor is off and unplugged.

2.  Rotate pressure regulator knob fully counterclockwise.

3.  Rotate pressure regulator locking ring fully counterclockwise.

4.  Confirm that the outlet pressure is at zero (0) bar.

5.  Attach hose with quick connect air fitting to 6.35 mm (1/4 in.) 

quick connect coupler (regulated pressure) on air compressor. 
Make sure to push the hose adapter end fully into the coupler 
until the sleeve springs forward to lock it in place.

To disconnect an air hose or an air tool:

1. 

Rotate pressure regulator knob fully counterclockwise. 

2.  Confirm that the outlet pressure is at zero (0) bar.

3.  When disconnecting a hose from 6.35 mm (1/4 in.) quick coupler, 

always firmly hold release end of hose.

4. Pull back on the release sleeve on the 6.35 mm 

(1/4 in.) quick coupler.

5.  With a firm grip, pull out the quick connect air fitting that is 

attached to the quick coupler.

TURNING THE AIR COMPRESSOR ON/OFF

See figure 10.

1.  With the air compressor plugged in, pull the power switch to the 

ON position to power the compressor on.

2.  To turn the air compressor off, push the power switch to the OFF 

position.

NOTE:

 When the compressor is in the ON position, the air 

compressor will automatically turn on when the designated tank 
air pressure drops below the preset pressure limit. It will also shut 
off again when the desired pressure is reached.
