Operation (Continued)
Using fittings or air hoses which are too small
can create a pressure drop and reduce the
power of the tool. A 3/8" (I.D.) fitting with
1/4" NPT threads is recommended. Most
compressors are shipped with a short, 1/4"
I.D. hose. For proper performance and more
convenience, use a 3/8" I.D. hose. Hoses
longer than 50 feet should have a 1/2" I.D.

Never carry a
tool by the hose
or pull the hose to move the tool or
a compressor. Keep hoses away from
heat, oil and sharp edges. Replace any
hose that is damaged, weak or worn.
Possible Cause(s)
1. Grit or gum in tool
2. No oil in tool
3. Low air pressure
4. Air hose leaks
5. Pressure drops
6. Regulator set too low
1. Water in tank
2. Water in the air lines/hoses

The air tool must be lubricated before
storing. Follow the air motor lubrication
instructions with an exception to step 4. Run
the sander for only 2 to 3 seconds so more oil
will remain in the air tool when storing.

Corrective action
1. Flush the tool with Campbell Hausfeld air tool oil, gum
solvent, or an equal mixture of SAE 10 motor oil and
kerosene. If Campbell Hausfeld oil is not used, lubricate
the tool after cleaning
2. Lubricate the tool according to the lubrication
instructions in this manual
3a. Adjust the regulator on the tool to the maximum setting
(If applicable)
3b. Adjust the compressor regulator to tool maximum while
the tool is running free
4. Tighten and seal hose fittings if leaks are found
5a. Be sure the hose is the proper size. Long hoses or tools
using large volumes of air may require a hose with an
I.D. of 1/2" or larger depending on the total length of
the hose
5b. Do not use multiple number of hoses connected together
with quick connect fittings. This causes additional
pressure drops and reduces the tool power. Directly
connect the hoses together
6. Adjust regulator until tool reaches maximum speed
1. Drain tank. (See air compressor manual). Oil tool and
run until no water is evident. Oil tool again and run 1-2
seconds
2a. Install a water separator/filter (PA2121). NOTE: Separators
only work properly when the air passing through the
separator is cool. Locate the separator/filter as far as
possible from the compressor
2b. Install an air dryer
2c. Anytime water enters the tool, the tool should be oiled
immediately
