equal mixture of SAE # 10 motor 011 and kerosene.

tructions in this manual.

while the tool is running free.
4. Tighten and seal hose fittings if leaks are found.
5-1. 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 12.7 mm (1/2") or larger
depending on the total length of the hose.
5-2. Do not use a multiple number of hoses connec-
ted together with quick connect fittings. This causes
additional pressure drops and reduces the tool power
Directly connect the hoses together.
6. Remove and inspect bearing for rust, dirt and grit
or worn race. Clean and regress bearing with bearing
grease.
1. Drain tank. (See air compressor manual).
Oil tool and run until no water is evident.
