Preparing the Mounting Surface
HEAVY OBJECT
To avoid personal injury and damage to the lightbar, an assistant should help handle
the lightbar assembly.
IMPORTANT: Planallcableroutingbeforecompletingtheinstallation.
1. Placethelightbaronthevehicleroofattheselectedlocation.Thelightbarshouldtypicallybe
installedapproximatelyoverthedriver’shead.
2. Adjustbothmountingbracketassembliesinoroutuntiltherubbermountingpadsrestnear
theedgeoftheroof,orgutter,wheretheroofismostrigid.
3. Centerthelightbarassemblysothattheendoftheassemblyandedgeoftheroofare
equidistantoneachsideofthevehicle(Figure 3onpage4).Tightenthe3/8-16hexnuts
(twooneachmountingbracket)installedinPreparing the Lightbar for Installation,steps2
and3.

4Vista Model XAPK-SC, -SD or XPK-SC, -SD Permanent Mount Kit
4. Tomaximizeaerodynamicefciencyandhigh-speedstability,itisrecommendthatthe
lightbarbemountedwithaone-inchorgreatergapbetweenthebottomedgeofthelightbar
andtheroof.Onahigh-crownedroof,oneinchmaynotbepossible.Inthiscase,adjustthe
lightbarashighaspossible.Adjustthemountingfeetonthemountingbracketasneeded.
5. Checktoensurethatthelightbarislevelfront-to-back.Ifitisnot,adjustthelevelby
rotatingthelightbarinthemountingbracketslots.Tightenalleight5/16Torxheadboltsthat
fastenthemountingfeettothemountingbrackets.
6. Usingthemountingbracketsasatemplate,scribetwodrill-positionmarksoneachsideof
thelightbar.
7. Removethelightbarassemblyfromthevehicleroof.Toavoidmarringtheplasticdomes,
placethelightbaronsoftragsorcardboard.
8. Turnthelightbarassemblyoversothatthebottomoftheassemblyfacesup.Securethe
mountingassemblytothelightbarusingtheeight#10hexheadthread-formingscrews.
9. Tightenthe3/8-16hexnuts(twooneachmountingbracket)installedinstep7ofPreparing
the Lightbar for Installation.Placethelightbarassemblyonthevehicleroofinthepreviously
determinedposition.

DRILLING PRECAUTIONS
Before drilling holes, check the area you are drilling into to be sure you do not damage
vehicle components while drilling. All drilled holes should be deburred and all sharp
edges should be smoothed. All wire routings going through drilled holes should be
protected by a grommet or convoluted/split loom tubing.
1. Beforedrilling,movethelightbarassemblyoutoftheway.Drillfour1/2-inchdiameterholes
atthescribeddrillpositionmarks.
2. InsertatoggleboltineachofthefourdrilledholesandsealtheholeswithRTV.Slidetwo
rubbermountingpadsovereachboltasyouinsertit(Figure 4onpage5).Usecautionto
avoiddroppingtheboltsthroughtheholesbeforetherubbermountingpadsareinstalled.
3. Placethemountingbracketsdownovertheendsofthetoggleboltsandsecurethemwiththe
jamnuts(Figure 4 on page 5).Tightenthejamnutjustuntiltherubberpadbeginstobulge.
Donotexceedatorqueof60in-lb.
