4. PREPARATION
4.1. Air Supply
4.1.1. Before connecting to an air supply ensure that the trigger catch release slide is not depressed (see fig.3).
4.1.2. You will require an air pressure between 60-120psi.
4.1.3.  WARNING! Ensure the air supply is clean and does not exceed 120psi while operating the nail gun.
Too high an air pressure and unclean air will shorten the product life due to excessive wear and may be dangerous, causing damage
and/or personal injury.
4.1.4. Drain the air tank daily. Water in the air line will damage the nail gun and will invalidate your warranty.
4.1.5. Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig.1.
4.1.6. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres).
The minimum hose diameter should be 1/4" I.D. and fittings must have the same bore.
4.1.7. Keep hose away from heat, oil and sharp edges. Check hoses for wear, and make certain that all
connections are secure.
4.2. Couplings.
Vibration may cause failure if a quick change coupling is connected directly to the air nail gun.
To overcome this, connect a leader hose to the nail gun. A quick change coupling may then be
used to connect the leader hose to the air line recoil hose (see figs 1 & 2).
