3. PREPARING TOOL FOR USE
3.1.
Assembly
3.1.1. Screw the scaling head fully onto the body as indicated above in fig.1.
3.2.
Air Supply
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.
3.2.1. Ensure needle scaler trigger is not depressed before connecting to air supply.
3.2.2. You will require an air pressure of 90psi, and a minimum flow of 6cfm.
3.2.3. Drain the air tank daily. Water in the air line will damage the needle scaler.
3.2.4. Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig.2.
3.2.5. Line pressure should be increased to compensate for unusually long air hoses (over 8
metres). The minimum hose diameter should be 1/4" internal diameter and fittings must
have compatible dimensions.
3.2.6. 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 (Sealey ref: AH2R or
AH2R/38). A quick change coupling may then be used to connect the leader hose to the air
line recoil hose. See fig.2 & fig.3.

4. OPERATING INSTRUCTIONS
WARNING! Ensure you read, understand and apply Section 1 safety instructions.
4.1.
Connect the needle scaler to the air supply as described 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.
