Sealey SA620 - Manual (Page 2)

3.1. Air Supply
p
WARNING! Ensure the air supply is clean and does not exceed 90psi while operating
the drill. 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.
3.1.1. Ensure drill air 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. Drain the air tank daily. Water in the air line will damage the drill.
3.1.4. Clean air inlet filter weekly. Recommended hook-up procedure is shown in fig 1.
3.1.5. 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.
3.1.6. 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 drill. To
overcome this, connect a leader hose to the drill (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 1 & fig 2.

WARNING! Ensure you read, understand and apply Section 1 safety instructions.
4.1. Turn front of chuck head to open, insert drill bit and turn chuck head to lock drill bit.
4.2. Connect the drill to the air hose as in Section 3.
4.3. The drill direction is changed by switching the forward-reverse lever above motor housing.
Check that the drill is set to operate in the required direction.
4.4. Depress the trigger to operate the drill accordingly.
DO NOT allow drill to free run for an extended period of time as this will shorten its life.
