1. SAFETY INSTRUCTIONS

1.2 GENERAL SAFETY

pWARNING! Disconnect drill from mains power before changing accessories, servicing or performing any maintenance.

3Maintain the drill in good condition (use an authorised service agent).

pWARNING! Keep all guards and holding screws in place, tight and in good working order. Check regularly for

damaged parts. A guard or any other part that is damaged should be checked, before the tool is used, to

ensure that it will operate properly and perform its intended function. The safety guard is a mandatory fitting

where drill is used in premises covered by the Health & Safety at Work Act.

3Check alignment of moving parts and check for possible broken parts.

3Replace or repair damaged parts. Use recommended parts only. Non-authorised parts may be dangerous and will

invalidate the warranty.

3Ensure the set screws of the head frame are screwed tight before using the drill.

3Secure the drill to a supporting structure to avoid the machine tipping, sliding or walking. Drill is designed for use

with drill bits only. No other accessory may be used.

3Ensure the chuck is securely fastened to the spindle.

3Remove adjusting keys and wrenches from the machine and working area before switching on.

3Use clamps or a vice (not included) to secure the workpiece. Available from your Sealey dealer. DO NOT secure

the workpiece by hand.

3Refer to speed chart for recommended drilling speeds.

pWARNING! Always wear approved eye or face protection when operating this drill. Use a face or dust

mask if dust is generated.

7DO NOT wear gloves when drilling.

1.1. ELECTRICAL SAFETY. p WARNING! It is the users responsibility to read, understand and comply with the following:

You must check all electrical equipment and appliances to ensure they are safe before using. You must inspect power supply leads, plugs and

all electrical connections for wear or damage. You must ensure the risk of electric shock is minimised by the installation of appropriate safety

devices. An RCCB (Residual Current Circuit Breaker) should be incorporated in the main distribution board. We also recommend that an RCD

(Residual Current Device) is used with all electrical products. It is particularly important to use an RCD with portable products that are plugged

into an electrical supply not protected by an RCCB. If in doubt consult a qualified electrician. You may obtain a Residual Current Device by

contacting your Sealey dealer. You must also read and understand the following instructions concerning electrical safety.

1.1.1. The Electricity At Work Act 1989 requires all portable electrical appliances, if used on business premises, to be tested by

a qualified electrician, using a Portable Appliance Tester (PAT), at least once a year.

1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of those appliances

and the safety of appliance operators. If in any doubt about electrical safety, contact a qualified electrician.

1.1.3. Ensure the insulation on all cables and the product itself is safe before connecting to the mains power supply.

See 1.1.1. & 1.1.2. above and use a Portable Appliance Tester (PAT).

1.1.4. Ensure that cables are always protected against short circuit and overload.

1.1.5. Regularly inspect power supply leads and plugs for wear or damage and connections to ensure that none is loose.

1.1.6. Important: Ensure the voltage marked on the product is the same as the electrical power supply

to be used, and check that plugs are fitted with the correct capacity fuse. A 13 amp plug may require

a fuse smaller than 13 amps for certain products.

1.1.7. DO NOT pull or carry the powered appliance by its power supply lead.

1.1.8. DO NOT pull power plugs from sockets by the power cable.

1.1.9. DO NOT use worn or damage leads, plugs or connections. Immediately replace or have repaired by

a qualified electrician. Where a U.K. 3 pin plug with ASTA/BS approval is fitted, in case of damage, cut off

and fit a new plug according to the following instructions (discard old plug safely).

(UK only - see diagram at right). Ensure the unit is correctly earthed via a three-pin plug.

a) Connect the GREEN/YELLOW earth wire to the earth terminal E.

b) Connect the BROWN live wire to the live terminal L.

c) Connect the BLUE neutral wire to the neutral terminal N.

After wiring, check there are no bare wires, that all wires have been correctly

connected, that the cable outer insulation extends past the cable restraint and that the cable restraint is tight.

Double insulated products are often fitted with live (BROWN) and neutral (BLUE) wires only. Double insulated products are always marked with

this symbol . To re-wire, connect the brown & blue wires as indicated above. DO NOT connect the brown or blue wires to the earth terminal.

1.1.10. NOTE: If this product requires more than a 13 amp electrical supply, then NO plug is fitted. You must therefore contact a qualified electrician to

ensure a 30 amp fused supply is available. We recommend you discuss the installation of a industrial round pin plug and socket with your electrician.

1.1.11. Cable extension reels. When a cable extension reel is used it should be fully unwound before connection. A cable reel with an RCD

fitted is recommended since any product which is plugged into the cable reel will be protected. The section of the cores in the cable

is important and should be at least 1.5mm2, but to be absolutely sure that the capacity of the cable reel is suitable for this product and

for others that may be used in the other output sockets, the use of 2.5mm2section is recommended .

7DO NOT allow untrained persons to operate the drill.

7DO NOT get the drill wet or use in damp or wet locations or areas where there is condensation.

7DO NOT operate the drill if damaged.

7DO NOT use drill in an area where paint fumes, solvents or flammable liquids pose a potential hazard. Keep flammable material away from

the drill when operating. Flammable waste, such as wiping or cleaning rags, must be placed in a closed metal container and disposed of correctly.

7DO NOT exceed the rated capacity of the drill.

7DO NOT operate the drill if any parts are missing as this may cause failure or possible personal injury.

7DO NOT leave the drill operating unattended.

7DO NOT operate the drill when you are tired, under the influence of alcohol, drugs or intoxicating medication.
