PREPARING NEEDLE PULLER FOR USE
3.1.
Air Supply
3.1.1. Ensure needle scaler valve (or trigger) is in the "off" position before connecting to the air
supply.
3.1.2. You will require an air pressure of 90psi, and an air flow according to specification.
3.1.3. 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.
3.1.4. Drain the air tank daily. Water in the air line will damage the needle scaler.
3.1.5. Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig 1.
3.1.6. 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
inside dimensions.
3.1.7. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that
all connections are secure.
3.2. 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.1 & 2.

4. OPERATING INSTRUCTIONS
WARNING! Ensure you read, understand and apply safety instructions before use.
4.1.
Remove the SA51 from the package. The tool should be assembled and ready to use.
4.2.
Connect the needle scaler to the air hose as in chapter 3.
4.3.
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.
