HARD SURFACE.
CAUTION: Prevent possible injury from flying
chips if compressed air is more than 210 kPa
(2.1 bar) (30 psi). Reduce compressed air to
less than 210 kPa (2.1 bar) (30 psi) when using
for cleaning purposes. Clear area of bystanders,
guard against flying chips, and wear personal
protection equipment including eye protection.
2. If this does not remove dust, use compressed air under
210 kPa (2.1 bar) (30 psi).
3. Direct air up and down the pleats from inside to
