WARNING!YOURE RESPONSIBLE FOR ARCHERY SAFETY

Please read the following safety information.Disregarding these rules may cause serious injury toyourself, others, or property.

1. NEVER DRY FIRE YOUR BOW. Dry fire means

to draw and release the bowstring without an arrow.Firing a bow without an arrow to absorb the energycan cause severe damage to your bow and possibleinjury to the shooter or others nearby. Let-down thebow slowly and carefully from any drawn position.

2. NEVER EXPOSE YOUR BOW TO EXTREME

HEAT OR PROLONGED EXTREME DAMP.

Excessive heat, such as that experienced on a sunnyday inside a closed vehicle, could cause limb failure.Prolonged storage in a hot dry attic or damp base-ment could also be damaging. Store the bow prop-erly when it is not in use.

3. CAREFULLY INSPECT YOUR BOW BEFORE

EACH USE. Carefully note the condition of the bow-string, limbs and riser before you shoot. Frayed bow-strings should be replaced. Damaged or suspectlimbs should be reported to your local dealer for

inspection or replacement.

4. BE SURE OF YOUR BACKSTOP. Make sure thatthe backstop you use is large enough to catch a strayarrow and that it is thick enough that the arrow can-

not completely penetrate it. Make sure that it is posi-tioned in a safe direction away from dwellings andother people.

5. BE SURE OF YOUR TARGET. Make sure thatthere are no persons, livestock, buildings or other

objects behind or near your target. Be absolutelysure of your target in low light conditions.

6. INSPECT ALL ARROWS. Before shooting,inspect your arrows for defects. Discard cracked ordented shafts. Replace damaged or loose fletchingand nocks.

7. ALWAYS BE SAFE. Never shoot straight up. Becareful around strings and cables when using broad-heads. Cutting strings and cables can cause seriousdamage to your bow and possible injury to you orothers. Do not draw the bow beyond its maximum

draw length. Never point or aim a drawn bow atanother person. Children mustbe supervised by anadult.

8. READ AND HEED ALL WARNINGS. Hoyt USAcannot be held responsible for injuries suffered or

caused by misuse, unsafe or improper arrow and bow combinations. Hoyt USA cannot be heldresponsible for injuries sustained when using analtered or modified Hoyt USA bow.

WARNINGThis bow is a deadly weapon.

Always abide by all safety advisements.Children must be supervised by an adult.

COMPOUND BOW MAINTENANCE

Your bow is a mechanical device and as such, is sub-

ject to wear and need of periodic inspection, adjust-ment and service. Hoyt USA recommends that youtake your bow to a Hoyt authorized pro shop at leastonce a year for a yearly professional maintenance andinspection. Areas to be inspected are axles, spacers,lubrication of axle bushings (Hoyt Cam & 1/2 Systembows do not require axle bushing lubrication), e-clips,

strings, cables, limbs and riser.

The following information provides helpful instruc-tion on the proper care and maintenance of your newHoyt bow. Keep this manual as a handy guide forfuture reference.

STRINGS AND CABLESApply a light coat of bowstring wax to your bowscables and string on a regular basis. Hoyt USA sug-gests once every two weeks during peak use. Use ahigh quality bowstring wax available at your localHoyt pro shop. This will keep your bows strings and

cables in good condition. To assure best resultsreplace your string and cables when wear is evidentor every two years under normal use conditions.


9/24

Insist that Hoyt USA string and cables be used onyour bow. Beware of lesser quality string and cablesas they may alter the performance of your bow or

cause damage to it.

ECCENTRIC LUBRICATIONFor conventional bearings or bushings, a light spotlubrication of the axles where they pass through theeccentric should be done on a regular basis (1,500 -

2,000 shots). In adverse hunting conditions wheredirt, dust or moisture are encountered, lubricationmay be done on a daily basis. Hoyt USA recommendsyou use a silicone or Teflon based lubrication or anyother quality grease available at your local Hoyt USAPro Shop. It is not recommended that you usePenetrating Oils such as WD-40, EZ-#7, Fast Break,

etc.

Note: Cam & 1/2 System bows feature sealed stain-less steel ball bearings which do not require lubrica-tion.

BOW PRESS USENever allow your bow to be put into a bow pressunless it is operated by a knowledgeable bow techni-cian. Hoyt USA recommends that all necessaryadjustments requiring the use of a bow press be doneby an authorized Hoyt pro shop.

fig 1 (An Example of a Double Pull Bow Press)

Always use a double bow press like that shownin figure 1 when working on your bow. Never

use a single pull bow press. (See fig 2)

COMPOUND BOW SETUP

REST SELECTIONThere are two basic types of arrow rests: ShootThrough and Shoot Around. (See fig 4) Shootthrough rests are designed for release shootersas arrows shot using a release bend vertically.

Before putting your bow in a bow press, loosenboth the top and bottom weight lock screws andweight adjustment bolts 5 to 7 turns from maxi-mum weight (when limb bolts are fastened all theway down). When putting your bow in thepress, never put pressure on the riser! Alwaysposition the rollers at the base of the limbs (wherethe limbs enter the limb pockets). (See fig 3)

fig 3


12/24

Shoot around rests are designed for finger shoot-ers as arrows shot by fingers bend horizontally.Hoyt USA recommends that you seek the adviceof a qualified pro shop for the proper rest selec-tion for your style of shooting.

NOCK SET INSTALLATIONA nock point is a reference on the string thatmarks the exact location for you to nock yourarrow. The arrows nock is positioned under thenock set. To install the nock set at the proper

position begin by slipping the nock set on thestring. Then, using your rest as a reference, posi-tion the nock set just above level. A finger shoot-er should initially position the nock set atapproximately 3/16 above level. The releaseshooter should position the nock set so that the

arrow sits at a 90 degree angle with the stringand adjust height as needed. (See fig 5) Once thenock set is at the desired location use a special set

of nocking pliers to crimp the nock set into place.NEVER shoot a bow without a nock set or with anock set that has not been properly crimped. Forproper installation Hoyt USA recommends thatthis be done by a qualified pro shop.

CABLE GUARD INSTALLATION

All Hoyt USA bows are designed with a built incable guard bar attachment. Before mounting thecable guard bar, you must remove the rubber-bands used only for shipping purposes. To insertthe cable guard bar, simply slide the bar throughthe two mounting holes on the riser making sure

that the bar is pushed completely through andflush with the end of the front mounting hole.

After the bar has been inserted fasten with the1/4-20 x 1/2 set screws provided. (See fig 6)

CABLE GUARD GLIDE INSTALLATIONTo prevent your bows cables from rubbingagainst each other, Hoyt USA uses a specially

designed cable glide that hasoff-set cable slots. To correctly

install the glide on all Hoyt bows, first place the glide onthe cable guard bar. (See fig 7)Next, push the control cableinto the shorter front slot.Then, push the buss cable into

the longer rear slot.CAUTION: Do not pull bowback without proper installation of cable guardbar and glide.

TILLER ADJUSTMENT

Tiller is the difference in distance between theupper limb to the string and lower limb to thestring measured from the base of the limbs(where the limb and riser meet) at a 90 degreeangle to the string. (See fig 8)

The main function of tiller is to allow the archer tomore easily and comfortably aim during the drawand release of the shot. Most bows will shoot best

near even tiller whichmeans the distance fromthe string to the limb isthe same on top and bot-tom. Tiller adjustmentsare made by adjustingeither limb weightadjustment bolt. (Seedraw weight adjustmentsection pg. 15) Example:If you have too muchtiller on the bottom limb,decrease the weight onthe top limb or increasethe weight on the bot-tom. Hoyt USA recom-mends that you initially

set tiller equal top and bottom.

CENTERSHOTCentershot is the alignment of the arrow in thepower path of the string. This is accomplished by moving the arrow rest left or right. Releaseshooters should line the arrow up with or justslightly outside of the power path of the string.(See fig 9) Finger shooters should position thearrow so that the tip is just to the outside of thepower path of the string. (See fig 9)

Centershot is critical to how accurately a bowwill perform. These are initial centershot set-tings, for proper alignment Hoyt USA recom-mends this be done by a qualified pro shop.

FLETCH CLEARANCEFletch clearance is the ability of your vanes or fletch-ings to pass cleanly by or through your arrow restwithout impacting the rest so severely that the arrowsflight path is disrupted. It is necessary that you haveadequate vane clearance to achieve proper arrow

flight. (See fig 10)

COMPOUND BOW ADJUSTMENT

DRAW WEIGHT ADJUSTMENT

Weight adjustments can easily be made by turning theweight adjustment bolt clockwise to increase weightor counter clockwise to decrease weight. Note: Alwaysturn the top and bottom adjustment bolts in equalamounts. Some Hoyt USA model bows are equippedwith a Dual Locking Pocket System. Before draw

weight adjustments are made onthese models you must firstloosen the pocket locking screwslocated on both sides of thepocket. (See fig 11) Whenadjustments are completed, re-tighten the pocket locking

screws.

DRAW LENGTH ADJUSTMENT (INNER-CAMADJUSTABLE MODULES)Many Hoyt bows utilize the inner-cam adjustablemodule for draw length adjustment. The inner-cam

can generally be adjusted without the aid of a bowpress.

CAM & 1/2 DRAW LENGTH ADJUSTMENTTOP CAM: To adjust the draw length on Hoyts Cam& 1/2 (inner-cam) model bows, use a standard allenkey to loosen the fastening screw and to remove the

draw length screw. (see fig 12) Rotating the inner-camin the (+) direction will lengthen the draw. Rotatingthe inner-cam in the (-) direction will shorten the

draw. Each let-tered position willprovide approxi-

mately l/2 inchlonger/shorterdraw than theprevious setting.Once the inner-cam is in thedesired location,reinstall andtighten the drawlength screw first

and then the fastening screw.

BOTTOM CAM: Remove the draw length screw,

rotate module to the same lettered position as the topmodule, and replace. (see fig 13) Note: You mustmake the same adjustments to the top and the bot-tom inner-cams or the bow will not tune properly.

OPTIMIZING CAM & 1/2 PERFORMANCEIn order to verify the factory setting of your Cam &1/2 System bow you should examine the cam's

built-in reference holes. When viewing the module

side of the top cam, at least part of the control cableshould lie over the reference hole (see fig14). Whenviewing the module side of the bottom cam, at leastpart of the buss cable should lie over the reference

hole as shownin fig 15. It is

not necessaryto have thecables exactlycentered overthe referenceholes. Moduleposition will

not affect thereference holelocation.

OPTIMIZING SPIRAL CAM & 1/2 PERFORMANCETo verify factorysetting of bows

featuring HoytsSpiral Cam &1/2 System, youshould examinethe cams built-in performancemarks. On boththe top and bot-tom cam, thelimb should liesomewhere in

between themarks. (See fig

16) It is not necessary to have the limb exactly cen-tered between the marks. The let-off of your SpiralCam & 1/2 bow can be adjusted using a standardallen key. The ATA let-off values of the Spiral Cam& 1/2 System vary from 55% to 65%. You will noticethe four draw-stop holes on the bottom cam num-

bered 1 through 4. (See fig 17) For 55% let-off, the

draw-stop pegshould be placedin hole #4.Simply removethe draw-stop pegfrom its original

position, place it inthe desired posi-tion, and tighten.CABLE

Each Hoyt Spiral Cam & 1/2 System bow wasshipped in the 65% let-off (draw stop peg position#1). Note: changing the draw-stop position to

manipulate let-off will alter draw length by approx-imately 1/8 for each draw-stop hole; draw lengthwill be shortened when changing to a lower let-offposition and lengthened in higher let-off positions.

TUNING YOUR BOWThere are numerous methods you can use when tuningyour Hoyt USA bow. Hoyt USA recommends working

closely with your local pro shop when tuning yourbow to ensure best results.

BROADHEADSMost archers discover that they must make slight tun-ing adjustments when switching from practice points

to broadheads (even at the same weight). Broadheadscreate a dramatic aerodynamic change in arrow flight.For this reason, slight adjustments may need to bemade in nocking point height, rest position or bowweight to achieve desired broadhead flight. Alwaystest shoot broadheads before hunting to ensure propersight settings. Even expandable broadheads may

require different sight settings than field points.
