3.1. Ensure the jack pneumatic switch (or trigger) is in the "off" position before connecting to the air supply.
3.2. You will require an air pressure of at least 100psi (max 140psi) and an air flow of 9.5cfm to get the best
performance from this jack. Use a compressor of 3HP or above.
3.3.
❐
WARNING!
Ensure the air supply does not exceed 140psi while operating the jack. Too high an air
pressure and unclean air will shorten the products life due to excessive wear, and may be dangerous
causing possible damage and personal injury.
3.4. Keep the air hose between the compressor and the air jack as short as possible, and install an air filter
and oiler (fig 1).
