The air hose leaks .
The air pressure drops .
There is a worn rotor blade in the motor .
There is a worn ball bearing in the motor .

Solution
Flush the tool with air tool oil or gum solvent .
Lubricate the tool according to the lubrication
instructions in this manual .
□ Adjust the regulator on the tool to the
maximum setting .
□ Adjust the compressor regulator to the tool's
maximum setting of 90 psi .
Tighten and seal the hose fittings with pipe thread
tape if leaks are found .
□ Ensure the hose is the proper size . Long
hoses or tools using large volumes of air may
require a hose with an I .D . of ½" or larger
depending on the total length of the hose .
□ Do not use a multiple number of hoses
connected together with a quick connect
fitting . This causes additional pressure drops
and reduces the tool power . Directly connect
the hoses together .
Replace the rotor blade .
Remove and inspect the bearing for rust, dirt, and
grit . Replace or clean and grease the bearing with
bearing grease .
Drain the tank . (See the air compressor manual
for instructions .) Lubricate the tool and run it until
water is not evident . Lubricate the tool again and
run for 1-2 seconds .
Lubricate the air motor and the impact mechanism
according to the lubrication instructions in this
manual .
Adjust the regulator on the tool to the maximum
setting .
Replace the worn impact mechanism components .
Replace the broken impact mechanism
components .
