3. AIR SUPPLY
3.1. Ensure the jack pneumatic switch is in the "off" position before connecting to the air supply.
3.2. You will require an air pressure of more than 100PSI (max 145PSI) and an air flow of 14cfm to get the best performance from this jack.
3.3. p WARNING! Ensure the air supply does not exceed 145psi 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).
3.5. Drain the air tank daily. Water in the air line will damage the jack.
3.6. Clean the air inlet filter screen weekly.
3.7. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose diameter should
be 3/8" I.D. and fittings must have the same inside dimensions.
