PREF ACE
THE STRONG INTERNATIONAL XENON GLADIATOR II Model 47050 is a direct cur­rent follow spotlight complete with a xenon lamphouse, power supply , optical system, color boomerang, and base stand assembly. The spotlight assembly consists of the arc lamp, variable focus lens system, color boomer­ang, and base. The separate xenon power supply completes the installation.
ONLY THE SPECIAL XENON POWER SUPPLIES manufactured by Strong International can be used with the Gladiator II. For installation and operation of the power supply , see the instruction manual furnished separately .
THE XENON LAMPHOUSE utilizes a 2500 watt xenon bulb designed for horizontal opera­tion, and a deep ellipse metal reflector as a light source. The reflector is designed to operate in a fixed position, and is dichroic (“cold”) coated to reduce heat in the projected light. A lens blower and heat filters, mounted in the spotlight optical system, further reduce heat at the projection lens and color media.
ONL Y XENON BULBS designed for horizontal operation should be used in this follow spot.
®
Those bulbs presently approved for the Gladiator II include the Hanovia
XH2500HS, the Osram XBO2500W/HS OFR, and the ORC® XM2500HS. All required bulb cabling is provided in the xenon lamp­house, and bulb adapters are not required.
ADJUSTMENT CONTROL for the xenon bulb is located at the rear of the lamphouse behind
the access panel. The adjustments control the horizontal, vertical and focal movement of the bulb.
INSTRUMENTATION of the lamphouse includes a running time meter and a DC ammeter. The running time meter indicates the number of hours the bulb has been in operation. The ammeter displays the operating current of the lamp. A push button switch, located below the ammeter, changes the meter reading to indicate the DC voltage at the arc.
THE LAMPHOUSE COOLING BLOWERS are internally wired and operate on AC voltage derived from the xenon power supply . These blowers are required to maintain a safe operating temperature at the bulb seals. The blowers operate continuously until the xenon power supply is de-energized. Air flow interlock switches prevent operation of the lamp if the intake or exhaust blowers are not operating or failing to move adequate air.
THE IGNITER is equipped with an emergency ignition switch, located on the top of the lamp­house below the plug button. Pressing this switch bypasses the relay contacts on the igniter printed circuit board. DO NOT hold this switch for longer than one second to prevent transformer damage.
THE TWO ROCKER SWITCHES on the instrument panel are labeled MODE and LAMP. The MODE switch permits operation of the lamphouse from a remote location when placed in the “AUTO” position, or by the operator at the lamphouse when in “MAN.” The normal setting for this switch, in a follow spot application, is in the “MAN.” position.
®
THE LAMP SWITCH is provided for manual bulb ignition when the MODE switch is in the “MAN.” position. The LAMP switch must also be “ON” to complete the ignition circuit when operating from a remote location.
XG2/001
THE LAMPHOUSE is supplied with a 13 foot cable containing the DC leads, the AC control wires, and the ground wire. The cable terminates in a multiple pin MS connector keyed to mate with the receptacle on the power supply .
WHEN TRANSPORTING THE SPOTLIGHT, it is necessary to remove the xenon bulb and place it in its original shipping container to prevent breakage. See the SAFETY PROCEDURES section following, and permit only authorized personnel to handle the xenon bulb.
IF AT ANY TIME you have a suggestion, or desire aid in securing anticipated results, write directly to STRONG INTERNATIONAL, 4350 McKinley Street, Omaha, Nebraska 68112.

INSTALLATION AND SETTING UP SPOTLIGHT
THE XENON GLADIA TOR II is shipped in sections which must be assembled. Lifting straps
on the yoke assembly permit assembling the spotlight on the floor and later hoisting it to an elevated position.
ASSEMBLE THE FOUR BASE LEGS to the lower square section of the base column using the 3/8-16 x 2-3/4 inch hex head cap screws and lockwashers provided. Insert a leveling foot and locknut in each of the four leg brackets and level the base before continuing the installation.
WHEN INSTALLED in a permanent location, the leveling feet must be removed, and the clearance holes in the base leg brackets used for hardware (user supplied) to bolt the base to the floor or platform. If it is desired to have the unit portable, when operating, the leveling feet must be adjusted down until the weight of the spotlight has been shifted from the casters to the leveling feet.
THE INNER TUBE and support yoke has three holes to permit adjusting the height of the spotlight. The three holes are on four inch centers and will allow an optical height of approximately 53 inches, 57 inches, and 61 inches above floor level to the optical center of the lamphouse and lens system. The leveling feet may be adjusted through an additional two inch range. Insert the height location pin through the hole in the outer tube and one of the holes in the inner tube.
THE HORIZONT AL SWING and vertical tilt locking knobs are on the right hand (operating) side of the yoke assembly . Tighten both of these locking devices securely before attempting to place the lamp­house and lens system on the support yoke.
PLACE THE LAMPHOUSE and lens system on the yoke assembly , with the spot size control handle to the right hand (operating) side, the same as the locking controls on the yoke. Line up the four mounting holes in the bottom of the base rail with the four mating holes in the support yoke and secure using the four sets of 3/8-16 screws, nuts and washers.
A TTACH THE LAMPHOUSE CABLE CONNECTOR to the mating receptacle on the power supply . The lamphouse and power supply connectors are keyed for correct pin alignment; make certain pins are seated before tightening the locking ring. DO NOT energize the xenon power supply before the xenon bulb is correctly installed into the lamphouse.
EARLIER MODELS of Strong xenon spotlights included a heavy-gauge green ground wire in the lamphouse cable assembly . This ground wire was attached to a ground stud connected to the power supply cabinet. Current models of Strong power supplies include a 1/4-20 stud in the cabinet adjacent to the MS connector to allow ground termination of older spotlights.

SAFETY PROCEDURES
READ CAREFULLY BEFORE INSTALLING XENON BULB
THE XENON BULB is highly pressurized. When ignited, the normal operating temperature of the bulb increases the pressure to a level at which the bulb may explode if not handled in strict accordance to the manufacturer’s operating instructions.
THE BULB is stable at room temperature, but may still explode if dropped or otherwise mis­handled. Breakage resulting from transport and handling is not covered by the bulb manufacturer’s warrranty , and it is strongly recommended to dismaount the xenon bulb when transporting the spotlight.
REFER bulb replacement and service to QUALIFIED PERSONNEL with adequate protective clothing (face shield, clean cotton gloves, welder’s jacket). For routine lamphouse service, observe the follow­ing rules:
1. Allow the bulb to cool to room temperature before opening the lamphouse. Put on protective clothing
described above.
2. De-energize the xenon power supply at the AC source before opening the lamphouse compartment.
3. When possible, encase the bulb in its protective cover when cleaning or servicing the lamphouse inte-
rior. The bulb, when outside the lamphouse, must be encased in the cover.
4. Clean the bulb after it has cooled to room temperature. Do not touch the quartz envelope of the bulb;
fingerprints will burn in and create hot spots which may shorten bulb life. If fingermarks are made, they should be carefully removed with methyl alcohol and cotton prior to bulb operation.
5. Never view an ignited bulb directly. BLINDNESS OR PERMANENT EYE DAMAGE MAY BE
INCURRED.
6. Use only xenon bulbs designated as OZONE FREE. When possible, vent the lamphouse exhaust to
outside atmosphere.
7. Maintain the lamphouse blower in good operating condition. Keep the blower inlet clean for unre-
stricted air flow .
8. To insure maximum bulb life, operate the lamphouse blower and the exhaust system for at least ten
minutes after extinguishing the bulb.
9. If returning a bulb for warranty adjustment, pack it in its original shipping container. Complete and
return all required warranty information.
XG2/005
10. Dispose of expired bulbs that are beyond warranty in the following manner: Wrap the bulb tightly in several layers of canvas or heavy cloth. Place it on a hard surface and shatter the envelope with a sharp hammer blow . DO NOT place an unshattered bulb in an ordinary refuse container.
11. DO NOT PERMIT UNAUTHORIZED PERSONNEL TO PERFORM OR A TTEMPT ANY PHASE OF XENON BULB HANDLING OR SERVICE.

BULB INSTALLATION
OBSER VE ALL SAFETY PROCEDURES when working around the xenon bulb. Open the lamphouse access door by removing the tamperproof screws using the special screwdriver supplied. The igniter lead and contact clamp are tied off for shipping. Free the clamp and slide it over the rear bulb support collet.
THE BULB SUPPORT YOKE in front of the reflector has three horizontal positioning holes to permit setting the height of the yoke. The Gladiator II uses only the upper two holes. The spotlight is shipped set up for use with the Hanovia XH2500HS bulb normally supplied with the unit, and the spring pin is through the top hole. Because of a different end cap dimension, the bulb yoke must be raised and the pin installed in the center hole if an Osram XBO2500W/HS bulb is used. The yoke may be repositioned by loosening the 8-32 set screw in the support post. Tighten the set screw after setting the yoke position.
REMOVE THE PLASTIC PROTECTIVE COVER from the xenon bulb only if necessary. Handle the bulb by the metal end caps only. Insert the bulb into the lamphouse, passing the anode (+) end cap through the center hole of the reflector. Take care not to bump or scratch the surface of the reflector.

INSERT THE ANODE (+) PIN into the rear support collet and contact clamp. Rest the cathode (-) end cap in the front bulb support yoke. Seat the anode (+) pin into the rear support collet as far as possible for correct focus travel. Securely tighten the socket head clamping screw in the anode contact.
REST THE CATHODE END CAP in the “V” of the bulb yoke. Install the cathode contact clamp over the cathode (-) pin. Firmly tighten the socket head clamping screw for a secure electrical contact. Dress the negative DC lead attached to the contact clamp directly in front of the bulb support yoke to minimize the projected shadow .
RECORD the bulb serial number, date, and lamphouse hours on the Xenon Bulb Record on the inside back cover of this manual. This information will be needed in the event of a bulb warranty adjustment.
IT IS RECOMMENDED to use the above-mentioned lamphouse cables when installing the xenon bulb. Anode leads supplied with bulbs are generally removable. If it is necessary to use the bulb anode lead, remove the lamphouse igniter lead, and use the clamp to secure the bulb to the support collet. Attach the bulb lead terminal to the igniter post; insulate the lead well and dress the lead away from grounded lamphouse components.
XG2/007
ESTABLISH A ROUTINE of periodically checking all electrical connections for tightness.
Loose contacts, particularly in the DC circuit, will cause overheating and damage the xenon bulb and other components. Normal xenon bulb warranties allow no credit for bulb damage caused by overheating.
REFER TO THE BULB MANUFACTURER’S INSTRUCTIONS regarding bulb rotation. Most bulb manufacturers recommend rotating the bulb 180° at 50% of warranty hours. After rotating the bulb, operate at maximum allowable current for several hours, and then return to the nominal operating current.
IN THE EVENT of a bulb warranty claim, the bulb must be packaged in its original shipping container, and returned with all required warranty forms completed. Contact the dealer through whom the bulb was originally purchased for correct procedures and Return Authorizations.
IT IS A COMMON PRACTICE to replace the bulb at the expiration of its warranty period. If a xenon bulb explodes in operation, the reflector and other lamphouse components are frequently damaged. The xenon bulb manufacturer will extend no credit for a replacement reflector if the defective bulb is beyond war­ranty. Explosion-damaged reflectors are to be returned to the bulb supplier, NOT Strong International, unless the bulb was supplied by Strong.
ARC STABILIZATION MAGNET
THE XENON BULB used in the Gladiator II lamphouse requires an arc stabilization magnet. This magnet is located on the lamp base behind the reflector. This magnet is preset at the factory and should not require adjustment. Should it become necessary to adjust the magnet, the following procedure must be followed. Observe all bulb safety procedures when working in the lamphouse compartment.
THE NORMAL ARC, when viewed through the arc viewing port, will appear as in Figure “A.” This represents the correct magnet position. Figure “B” shows the position of the arc when the magnet is too low . Raise the magnet on its adjustment bracket to lower the arc to the position illustrated in Figure “A.” Figure “C” shows the position of the arc when the magnet is too high. Lower the magnet to raise the arc to the position illustrated in Figure “A.”
THE MAGNET must always be installed with the longest portion of the magnet nearest the bulb, and with the NORTH (N) pole pointing to the operator side access door. Reversing the magnet will cause bulb flicker, and may inhibit bulb ignition. In new equipment, the magnet is normally in the center of the adjustment range. Changes in the magnet position are required only to correct an improperly burning arc (Figure “B” or “C”).
ANY REPLACEMENT MAGNET should first be installed in the center position of the adjustment range. Raise or lower the magnet as required to center the arc as illustrated in Figure “A.”
XG2/008
OPERATION
INSTALL THE GLASS HEAT FILTER into the bracket mounted on the rear of the fadeout
and douser support housing. NOTE: The coated side of the filter, with the XX or other marking, must be facing the reflector. Reach through the side door and nose opening of the lamphouse, slide the filter into the slot in the top angle bracket, and lower it into the bottom slotted bracket.
REMOVE THE PLASTIC COVER from the xenon bulb. DO NOT ignite the lamp with the
cover on the bulb. Store the cover for future re-use.
CLOSE AND SECURE the lamphouse door using the tamperproof screws and special screw­driver supplied with the lamphouse. Engage the cam lock and install the security screw. The door must be completely secured to actuate the interlock switch and permit lamp ignition. Place the MODE switch in the “MAN.” (manual) position.
TURN ON THE MAIN LINE SWITCH and/or circuit breaker to energize the xenon power supply. The lamphouse blowers will start and the blower interlock switches will be actuated to permit lamp ignition. The blowers will operate continuously until the xenon power supply is de-energized.
PLACE THE LAMP SWITCH in the “ON” position and the lamp will ignite. If ignition does not occur, or the high voltage pulse is not apparent, press the emergency ignition switch on the top of the lamphouse under the plug button. Do not hold more than one second; release immediately upon lamp ignition. Use of the emergency ignition switch indicates an abnormal condition; see the TROUBLESHOOTING section following.
CHECK THE READING on the lamphouse ammeter. Nominal current for the 2500 watt xenon bulb is 90 amperes. DO NOT , AT ANY TIME, exceed 100 amperes. Output current is adjusted at the power supply; see power supply manual for instructions. Operation of a new bulb is normally started at the lower end of its range (80 A.), and current is gradually increased as the bulb ages to maintain light output.
PRESS THE SMALL PUSH BUTTON SWITCH located below the ammeter to read the DC voltage at the arc. This permits immediate calculation of the power at which the lamp is operating (volts x amperes = wattage). Holding this switch in during the ignition cycle will also briefly indicate the “no load” (open circuit) DC voltage applied to the xenon bulb for ignition.
REMOVE THE REAR COVER PLATE below the instrument panel by withdrawing the two plastic plungers. This exposes the bulb positioning controls in the lamphouse back casting.
TO FOCUS THE XENON BULB and obtain the best light on the stage, the two methods outlined below are the most suitable.
MOVE THE SPOT SIZE CONTROL HANDLE (trombone) on the large lens carriage all the way forward to project the smallest spot possible; place the iris, masking shutters (choppers) and the fadeout douser blades in their full open positions. Project a spot to a wall or similar flat perpendicular surface opposite the spotlight position.
XG2/009
THE CENTER SECTION of the bulb positioning controls is a threaded member that focuses the bulb in relation to the reflector. T urning this adjustment moves the bulb in only one plane, into or away from the reflector. T urning this section clockwise moves the bulb away from the reflector . The small knurled screw to the left of this section can be tightened to lock the focusing mechanism after the following procedures have been completed.
THE LARGE THUMB SCREWS, on either side of the focusing control, lock the horizontal and vertical adjustment mechanism in position.
TURN THE CENTER FOCUSING SECTION of the bulb positioning control counterclock­wise until a small black spot is projected onto the wall. It may be best to run this adjustment both directions to permit positive identification of the spot.
LOOSEN THE TWO THUMB SCREWS, one on either side of the center focusing section, just enough to permit manual movement of the complete assembly. The bulb positioning control will now move around these two thumb screws, and as this control is shifted, the smooth shadow of the bulb electrode can be seen extending beyond the projected center hole in the reflector. The shadow of the electrode (black spot) must be centered in the projected hole of the reflector (shaded, less dense dark area).
MOVE THE CONTROL SECTION around the two screws until the black spot is as round as possible to project. It may be necessary to again turn the focus control to project a sharply defined black spot.
AFTER THE BLACK SPOT is as even around the outside as possible to project, and appears centered in the shaded reflector center hole, tighten the two large thumb screws to lock the position of the mechanism. Turn the center focus control to obtain the brightest light with the best light distribution. Rotate the lens spot focus control knob, located at the extreme front of the lens mechanism, to obtain the sharpest edge possible on the projected spot.
THE SECOND METHOD of focusing the xenon bulb is to project the spot to the stage, and working with the above lamphouse controls, adjust these controls to obtain a “hot spot” on the projected spot. Then center this “hot spot” on the projected light by moving the entire control section around the two thumb screws. Once this “hot spot” is centered in the projected light, lock the control in position with the two thumb screws and turn the center section to obtain a spot with an even distribution of light. Rotate the lens spot focus control knob to obtain a sharp edge on the projected spot.
XG2/010
THESE ADJUSTMENTS should not be disturbed until it is necessary to replace the xenon bulb. At that time, the procedure on obtaining a smooth, round black spot, or “hot spot,” may have to be repeated. Replace the cover plate over the bulb positioning controls.
BECAUSE OF NORMAL BULB AGING, and manufacturing tolerances between individual xenon bulbs, it may be necessary to operate lamps at slightly higher or lower current settings to maintain uniform light output when two or more spotlights are used in one installation. This entails a slight current output adjustment at the xenon power supplies. See the power supply manual.
TO EXTINGUISH the arc, place the LAMP switch on the instrument panel to “OFF.” The lamphouse blowers will continue to operate until the xenon power supply is de-energized. Allow the blowers to operate for ten minutes before turning off the power supply; a forced-air bulb cooling cycle is required by all bulb manufacturers.
DAILY OPERATION in the “Manual” mode requires only that the xenon power supply be energized, the MODE switch be left in the “MAN.” position, and the lamp switched ON and OFF by means of the LAMP switch. No bulb alignment or “warm up” are necessary. Always allow for the ten minute bulb cooling cycle.
OPERA TION IN THE “AUT O” MODE is intended for use only if the spotlight is to be used as a fixed spot without an operator at the equipment. Place the MODE switch in the “AUTO” position, and the LAMP switch to “ON.” The lamp will ignite when a sustained dry contact is made between the automation leads 3 and 6, and extinguish when the contact is opened. See the INST ALLATION DIAGRAM in the power supply manual. The lamphouse blowers will operate until the xenon power supply is de-energized; allow for ten minutes bulb cooling.
BEFORE OPENING the lamphouse enclosure for servicing, allow the blowers to operate for twenty minutes, or until the bulb has cooled to room temperature.
HANDLING THE SPOTLIGHT
GENERALLY THE BEST POSITION for the operator to stand is hear the center of the spot­light on the right side. The angle of tilt, the size of the porthole, and the layout of the spotlight position may dictate another location.
EACH OPERATOR will, after a few minutes of operation, generally develop his own system and position for most convenient operation.
THE HORIZONTAL SWING and vertical tilt are individually adjustable to give the desired degree of friction to suit the operator. The locking clamps are located on the right side of the yoke assembly.
THE EASE with which the spot size control handle (“trombone”) can be operated may be adjusted by means of the nylon friction brake screw in the outrigger of the large lens carriage casting. T o access this adjustment, open the color boomerang and remove the gel frames. Slide the large lens carriage to the extreme rear position. Reach through the boomerang housing and loosen the nylon friction screw locknut. Turn the nylon friction screw clockwise to increase drag, or counterclockwise to relieve. Tighten the locknut after the desired adjustment is reached.
XG2/011
OPERATION OF OPTICAL SYSTEM
THE IRIS CONTROL is the front lever which projects through the top of the optical system housing. When this lever is to the left (as viewed from the rear of the unit), the largest aperture is provided. Smaller apertures are obtained as the lever is moved to the right.
THE SPOT SIZE CONTROL HANDLE is located on the right hand side of the optical system just above the base rail. A variation of spot sizes from full flood to small spot can be obtained by moving the spot size control handle from one extreme to the other. Beam intensity is increased by this optical system when reducing from flood to spot, and maximum intensity is reached when the spot size control handle is in the extreme forward position.
THE MAXIMUM FLOOD SPOT is obtained with the iris control lever to the left (away from operating side) for the largest aperture and with the spot size control handle moved as far to the rear as possible.
SMALLER SIZED SPOTS are projected as the spot size control handle is moved forward. Most of the spot sizes needed will be produced with the iris in its maximum open position.
FOR A “HEAD SPOT,” or any spot smaller than can be obtained with the spot size control handle in its extreme forward position, shift the iris control lever to the right (toward operating side) for a smaller aperture. The iris control lever should always be returned to its extreme left position before the spot size control handle is again moved to obtain larger spots.
THE MASKING SHUTTER (chopper) lever is the middle lever projecting through the top of the optical system housing. The masking shutter blades are operated by this lever to shape the projected spot to a rectangle, strip spot, or dousing.
THE DISENGAGED POSITION of the masking shutter lever is to the extreme right (toward operating side) and varying degrees of masking to complete cutoff are obtained by moving the lever to the left (away from operating side).
THE ANGLE of the masking shutter blades can be adjusted to compensate for the horizontal projection angle. Remove the color boomerang and optical system housing, and loosen the screws holding each of the masking shutter blades enough to allow adjustments. Ignite the bulb and adjust the angle of the bottom blade by tapping with a screwdriver so its projected edge lies parallel to the footlights. Tighten the screw. Operate the masking shutter lever to close the blades. Adjust the upper blade to close in line with the bottom blade and tighten the screw .
THE FADEOUT MECHANISM AND DOUSER CONTROL is the rear lever projecting through the top of the optical system cover. This lever controls the intensity of light from complete fadeout when the lever is to the left, to full intensity when the lever is to the right.
THE SPOT FOCUSING CONTROL KNOB is located on the operating side of the optical system at the forward end above the base rail. This control is used to adjust the optical system for the length of throw . When making an adjustment, rotate the spot focusing control knob until the sharpest edge is obtained on the projected spot.
XG2/012
OPERATION OF COLOR BOOMERANG
THE COLOR BOOMERANG is equipped with six color holders and an ultraviolet filter.
Additional filter holders can be supplied by an authorized Strong International Dealer.
TO OPERATE INDIVIDUAL COLOR FILTERS, lower the desired filter selector lever. A
rocker catch located in the color disc housing holds the filter in position.
TO RELEASE A COLOR, push the filter release button or engage another color , thus releas-
ing the previous color automatically.
TO REPLACE A FIL TER HOLDER, open the hinged top of the color disc housing and lift out
the desired filter holder.
HIGH TEMPERATURE FILTERS (RoscoLux
®
or equivalent) cut to nine inch diameter are
required, and are secured in the filter holders with paper fasteners.
NOTE: WHEN PLACING COLOR FIL TERS in the boomerang, the less dense colors (pink,
amber) should be placed in the holders toward the rear of the boomerang (toward arc), and those of greater density (red, green) should be placed in the holders toward the front of the boomerang (away from the arc).
COLOR TEMPERATURE REDUCTION FILTERS, required for use with television and
videotape, are available from theatrical supply dealers.
XG2/013
MAINTENANCE
THE XENON GLADIATOR II SPOTLIGHT requires very little maintenance to keep it in good working order.
THE REFLECTOR should be cleaned periodically with a soft, clean, lint-free cloth to remove dust from the reflecting surface. If excessively soiled, the reflector may be cleaned with Windex
®
or an equiva­lent glass cleaner. DO NOT use abrasive cleaners of any kind. Clean the heat filter glass; replace with the coated surface toward the lamphouse.
CHECK ALL ELECTRICAL CONNECTIONS for tightness on a regular basis. Loose con-
nections, particularly in the DC circuit, may cause premature bulb failure and damage lamphouse components.
LUBRICA TE the bulb seal blower and the lens blower with two or three drops of non-detergent
oil once every six months. The exhaust blower is permanently lubricated.
THE XENON BULB should be checked occasionally for the presence of dust or foreign mate­rials. If necessary, clean the quartz envelope of the bulb with alcohol, and wipe dry with a clean, lint-free cloth. Observe all safety procedures when working with the exposed bulb.
THE INSIDE OF THE LAMPHOUSE and the blower squirrelcages should be cleaned peri­odically, depending on the dust conditions at each installation. Keep the blower inlet and outlet grilles clean to permit free air flow . Clean the actuator arms of the air flow switches to prevent dust build-up.
THE LENS SYSTEM should be kept clean to prevent any light reduction in the projected spot. Tighten the horizontal swing and vertical tilt locking clamps. Remove the color gels to reach and clean the back surface of the large lens. Remove the cover casting over the fadeout, chopper, and iris controls to remove the small projection lens which is held in place with a large spring-type retainer ring at the front of the lens barrel.
CLEAN THE PROJECTION LENS and large lens with with any cleaner approved for use on coated projection lenses. Replace the projection lens with the end with the FL marking ring toward the iris; secure with the retainer ring.
BEFORE TRANSPOR TING the spotlight, remove the xenon bulb from the lamphouse. Place the bulb in its plastic cover and original shipping container.
