OPERATION
MOVING THE AIR COMPRESSOR
See Figure 22, page 27.
 Raise the handle to the up position.
 Make sure the air compressor is off.
 Close the fuel valve.
 With your foot on the rear of the frame, tilt the machine
toward you until it balances on the wheels, then roll the
machine to the desired location.
 Allow 30 minutes of "cool down" time before storing the
machine.
CHANGING COUPLERS AND FITTINGS
FROM 1/4 IN. SIZE TO 3/8 IN. SIZE
See Figures 23 - 24, page 27.
This air compressor is equipped with high flow 3/8-in. air line
construction, but features couplings and fittings with 1/4-in.
internal diameter on all the air outlets since this is the most
common fitting size in use.
For optimal performance, you can replace these 1/4-in. cou-
plings with 3/8-in. internal diameter couplings and fittings
(not provided). This will allow you to achieve higher volume
air flow with lower pressure drop.
To replace the fittings:
 Turn off the air compressor and release all pressure from
both air tanks.
 Using an adjustable wrench, remove the 1/4-in. quick
connect couplers and air reducers.
 Apply pipe sealant to new 3/8-in. couplers and then install.
Tighten securely.
 Disconnect the unregulated air fitting from the unregulated
air intake coupler.
 Remove the 1/4-in. unregulated air intake coupler and air
reducer.
 Apply pipe sealant to new 3/8-in. coupler and then install.
Tighten securely.
 Remove the 1/4-in. unregulated air fitting and air reducer.
 Apply pipe sealant to new 3/8-in. air fitting and then install.
Tighten securely.
 Connect the new unregulated air fitting into the new
unregulated air intake coupler.
