English

COLD WEATHER CARE

Do not store the Stapler in a cold weather
environment.
Keep the Stapler in a warm area until beginning the
work.
If the Stapler is already cold, bring it in a warm area
and allow the Stapler to warm up before use.
1 Reduce the air pressure to 40 psi (2.8 bar 2.8 kgf/
2
cm ).
2 Remove all staples from the Stapler.
3 Connect the air hose and free-fire (blank-fire) the
Stapler.
The lowered air pressure will be enough to free-fire
the Stapler.
Slow speed operation tends to warm up the
moving part.
CAUTION:
Do not free-fire the Stapler at high pressure.
