ELECTRICAL INFORMATION

I N D U S T R I A L
POWER TOOLS
In the United Kingdom, 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. The HEALTH & SAFETY AT WORK ACT 1974 makes owners of electrical appliances
responsible for the safe condition of the appliance and the safety of its operator. If in any doubt about
electrical safety, contact a qualified electrician.
ELECTRICAL SAFETY
An RCCB (Residual Current Circuit Breaker) should be fitted in the mains electricity distribution board. If the
power supply is not protected by an RCCB, it is highly recommended that an RCD (Residual Current Device) is
used with all portable electrical products.
PLUG FITTING
A moulded UK 3 pin plug with ASTA/BS approval is already fitted for your safety.
If it becomes damaged, and needs replacing, cut off the plug and prepare the
wires. Use the following instructions:
a) Connect the GREEN/YELLOW earth wire to the earth terminal marked either
' E' or with the earth symbol' '.
b) Connect the BROWN live wire to the live terminal marked ' L'.
c) Connect the BLUE neutral wire to the neutral terminal marked ' N'.
d) After wiring, check there are no bare wires, that all wires have been correctly
connected, that the cable external insulation extends beyond the cable
restraint and that the restraint is tight.
EXTENSION REELS
When a cable extension reel is used it should be fully unwound before being
connected. Use at least 1.5mm 2 section cable or to be absolutely sure use 2.5mm
section cable.

GENERAL GUIDELINES FOR DRILLING
Always centre punch the position for driIIing. A centre punch is a pointed tool that marks the material to be
drilled with a small indent. It stops the drill bit moving from the desired position. Always start by drilling a
small pilot hole and gradually progress in drill diameter. When drilling metal, lubricate the drill tip with oil.
NEVER cool with water or water based lubricant otherwise an electric shock could occur.
DO NOT use oil when drilling copper or brass. Care should be taken when drilling copper and brass as the
drill bit will be prone to jamming. Small diameter drills require a higher speed and as the drill diameter
increases the slower the speed required. The following drilling speed chart is a guide only and only covers
the more common materials, drill diameters and speeds.
