Sealey SA50 - Manual (Page 2)

3.1. Assembly
3.1.1. Screw the scaling head fully onto the body as indicated above in fig.1.
3.1.2. Tighten the 3 grub screws located around the scaling head.
3.2. Air Supply
3.2.1. Ensure needle scaler trigger is not depressed before connecting to the air supply.
3.2.2. You will require an air pressure of 90psi, and a minimum air flow of 2.8cfm.
3.2.3.  WARNING! Ensure the air supply is clean and does not exceed 90psi while operating the needle
scaler. 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.
3.2.4. Drain the air tank daily. Water in the air line will damage the needle scaler.
3.2.5. Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig.2.
3.2.6. 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 inside dimensions.
3.2.7. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all
connections are secure.
3.3. Couplings
Vibration may cause failure if a quick change coupling is connected directly to the needle scaler. To
overcome this, connect a leader hose to the needle scaler. A quick change coupling may then be used to
connect the leader hose to the air line recoil hose. See fig.2 & 3.
3. PREPARING FOR USE
4. OPERATING INSTRUCTIONS

WARNING! Ensure you read, understand and apply safety instructions before use.
4.1. Connect the needle scaler to the air hose as in section 3.
4.2. To start the scaler, depress the trigger.
DO NOT allow the needle scaler to free run for an extended period of time as this will shorten its life.
4.3. Air flow may also be regulated by the air flow valve at the bottom of the handle (fig.1A).
