2 - Safety Precautions

The following instructions must be adhered to, in order to ensure a safe working environment

and the safety of the user.

Note: When unpacking or manoeuvring the searchlight into its fixing position, suitable

lifting points must be used in order to prevent damage to the equipment or personal

injury.

◼Prevent rain, snow, condensation and water droplets from contacting the lamp as this may

cause bulb failure and possible shattering;

◼Quartz halogen bulbs run with a high internal pressure in excess of atmospheric. Whilst the

construction is inherently strong, there is a slight risk of the bulb shattering;

◼Never look directly into an illuminated searchlight as this may cause severe damage to

eyesight. If it is necessary to inspect a lamp whilst in operation, always wear suitable

protective goggles;

◼Should it be necessary to examine the lamp with the lid removed, always use a protective

shield and wear goggles to ensure a safe working environment;

◼Never attempt to clean a lamp whilst in use;

◼Searchlights get hot. Never touch the unit when lit and always allow 15 to 20 minutes for

cooling down after turning the searchlight off;

◼Never place anything on or cover the searchlight when in use;

◼Ensure the lamp has cooled sufficiently before removal;

◼If undue force appears necessary to remove the lamp, the equipment should be inspected

by a competent person or contact the manufacturer;

◼When breaking a lamp for disposal, care must be taken to ensure the glass fragments are

safely contained. This operation must be performed out of doors in free air. In all

circumstances refer to the lamp manufacturers instructions packed with the lamp;

◼Due to the vast range of lamps available it may appear possible that more powerful lamps

can be used in the equipment than for which it was designed. Even when the unit will

physically accept a higher wattage or voltage lamp, this substitution is not recommended

and is dangerous. This action will also void any warranties on the equipment.

Always refer to the lamp manufacturer’s technical data when dealing with lamps.
