Cold Weather Operation

WARNING: Read the section titled Important Safety Instructions
at the beginning of this manual. Always wear eye and ear protection
when operating this tool. Keep the nailer pointed away from yourself
and others. For safe operation, complete the following procedures
and checks before each use of the nailer.
When operating tools at temperatures below freezing, complete
preparation procedures outlined above and follow the directions below.
1. Make sure compressor tanks have been properly drained prior
to use. Always drain the compressor tanks at least once daily
while using the nailer. This is especially important in cold weather
because any moisture in the air in the tanks will condense in the
cold temperature.
2. Keep the tool as warm as possible prior to use.
3. Put 5 to 10 drops of D
pneumatic oil containing ethylene glycol in the end cap.
4. Lower air pressure to 80 psi or less.
5. Actuate the tool 5 or 6 times into scrap lumber to lubricate o-rings.
6. Turn pressure up to operating level (not to exceed 120 psi) and
use tool as normal.
7. Re-lubricate with D
pneumatic oil containing ethylene glycol in the end cap at least
twice a day or after 4 hours of use.
Hot Weather Operation

Tool should operate normally. However, keep tool out of direct
sunlight as excessive heat can damage bumpers, o-rings and other
rubber parts.
