sToraGE
The impact wrench must be lubricated
before storing . Follow the air motor
lubrication instructions with an
exception to step 4 . Only run the impact
wrench for 2 to 3 seconds instead of 20
to 30 seconds because more oil needs
to remain in the impact wrench when
storing . The tool should be stored in a
cool dry place .

or an equal mixture of SAE 10 motor oil
and kerosene . If air tool oil is not used,

found
5 . a . 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 inch or larger depending on the
total length of the hose
b . Do not use a 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

and grit or worn race . Replace or clean and
regrease bearing with bearing grease
