WARNING! YOU’RE RESPONSIBLE FOR ARCHERY SAFETY Please read the following safety information. Disregarding these rules may cause serious injury to yourself, 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 energy can cause severe damage to your bow and possible injury to the shooter or others nearby. Let-down the bow slowly and carefully from any drawn position. 2.
4. BE SURE OF YOUR BACKSTOP. Make sure that the backstop you use is large enough to catch a stray arrow and that it is thick enough that the arrow cannot completely penetrate it. Make sure that it is positioned in a safe direction away from dwellings and other people. 5. BE SURE OF YOUR TARGET. Make sure that there are no persons, livestock, buildings or other objects behind or near your target. Be absolutely sure of your target in low light conditions. 6. INSPECT ALL ARROWS.
WARNING This 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 subject to wear and need of periodic inspection, adjustment and service. Hoyt recommends that you take your bow to a Hoyt authorized pro shop at least once a year for a yearly professional maintenance and inspection.
Insist that Hoyt string and cables be used on your bow. Some Hoyt bow models come equipped with the FUSE Custom String System. In those cases, always replace your strings with FUSE brand strings. Beware of lesser quality string and cables as they may alter the performance of your bow or cause damage to it. ECCENTRIC LUBRICATION Cam & 1/2 System bows feature sealed ball bearings which do not require lubrication.
Presses the bow in two places fig 1 (An Example of a Double Pull Bow Press) Always use a double bow press like that shown in figure 1 when working on your bow. Never use a single pull bow press.
Before putting your bow in a bow press, loosen both the top and bottom weight lock screws and weight adjustment bolts 5 to 7 turns from maximum weight (when limb bolts are fastened all the way down). When putting your bow in the press, never put pressure on the riser! Always position the rollers at the base of the limbs (where the limbs enter the limb pockets). (See fig 3) fig 3 COMPOUND BOW SETUP REST SELECTION There are three basic types of arrow rests: Shoot Through, Fall Away, and Shoot Around.
NOCK SET INSTALLATION A nock point is a reference on the string that marks the exact location for you to nock your arrow. The arrow’s nock is positioned under the nock set. To install the nock set at the proper position begin by slipping the nock set on the string. Then, using your rest as a reference, position the nock set just above level. A finger shooter should initially position the nock set at approximately 3/16” above level.
CABLE GUARD INSTALLATION All Hoyt bows are designed with a built in cable guard bar attachment. Before mounting the cable guard bar, you must remove the rubberbands used only for shipping purposes. To insert the cable guard bar, simply slide the bar through the two mounting holes on the riser making sure that the bar is pushed completely through and flush with the end of the front mounting hole. After the bar has been inserted fasten with the 1/4-20 x 1/2” set screws provided.

Control Cable TILLER ADJUSTMENT Tiller is the difference in distance between the upper limb to the string and lower limb to Buss the string measured from the Cable base of the limbs (where the limb and riser meet) at a 90 degree angle to the string. (See fig 6) The main function of tiller is to allow the archer to more easily and comfortably aim during the draw and release of the shot.
Example: If you have too much tiller on the bottom limb, decrease the weight on the top limb or increase the weight on the bottom. Hoyt re c o mmends that you initially set tiller equal top and bottom. CENTERSHOT Centershot is the alignment of the arrow in the power path of the string. This is accomplished by moving the arrow rest left or right. Release shooters should line the arrow up with or just slightly outside of the power path of the string.
FLETCH CLEARANCE Fletch clearance is the ability of your vanes or fletchings to pass cleanly by or through your arrow rest without impacting the rest so severely that the arrow’s flight path is disrupted. It is necessary that you have adequate vane clearance to achieve proper arrow flight. (See fig 9) fig.
of the pocket. (See fig 10) When adjustments are completed, re-tighten the pocket locking screws. DRAW LENGTH ADJUSTMENT (INNERCAM ADJUSTABLE MODULES) Many Hoyt bows utilize the inner- c a m adjustable module for draw length adjustment. The inner-cam can generally be adjusted without the aid of a bow press. CAM & 1/2 DRAW LENGTH ADJUSTMENT TOP CAM: To adjust the draw length on Hoyt’s Cam & 1/2 (inner-cam) model bows, use a standard allen key to loosen the fastening screw and to remove the draw length screw.

WARNING: Never remove the stainless steel control cable peg unless the string is relaxed in a bow press.
TOP CAM Buss Cable Yoke Bowstring Reference Hole Control Cable Reference Hole fig 13 cable should lie over the reference hole as shown in fig 14. It is not necessary to have the cables c e n t e red over the re f e rence holes. Module position will not affect the re f e rence hole location. Due to various limb configurations, some 2005 and later models are optimized with the cables slightly off the re f e rence holes.
Zephyr Cam & 1⁄2 Hoyt's Zephyr Cam & 1⁄2 is a high performance draw length specific cam system. Cams are available in 1⁄2 inch draw-length increments. Zephyr cams are also available in either 65% or 80% ATA let-off. Both top and bottom cams must be swapped out to change the bow's let-off. Adjustable Valley Technology (AVT) The Zephyr Cam & 1⁄2 features AVT, which allows the shooter to customize how the cam feels at full draw. An optional draw stop peg is included.
Zephyr Cam & 1/2 Optimization Zephyr Cam & 1/2 features performance marks on the bottom cam to indicate the optimum performance range for the cam. The limb should lie somewhere between the lines when the bottom cam is viewed from the logo side at brace. (See fig 16) In some cases the limb will not be exactly centered. This is by design since each individual cam/limb combination is factory optimized for performance and draw length.
OPTIMIZING SPIRAL CAM & 1/2 PERFORMANCE To verify factory Bowstring Buss Cable setting of bows featuring Hoyt’s Performance Control Spiral Cam & Marks Cable 1/2 System, you should examine the cams’ builtin performance Limb marks. On both the top and bottom cam, the limb should lie s o m e w h e re in STRING SIDE between the fig 17 marks. (See fig 17) It is not necessary to have the limb exactly centered between the marks. The let-off of your Spiral Cam & 1/2 bow can be adjusted using a standard allen key.
Simply remove the draw-stop peg from its original position, place it in the desired position, and tighten. Each Hoyt Spiral Cam & 1/2 System bow is shipped 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 appro ximately 1/8” for each draw-stop hole. Draw length will be shortened when changing to a lower let-off position and lengthened in higher let-off positions.
weight and may reduce the performance of the wheels on your bow. Hoyt recommends staying within the optimum performance range shown in Figure 19. If your draw length requires a cam position well outside the range shown in Figure 20, you may consider changing to a smaller or larger cam as needed. Please consult your local authorized Hoyt dealer. Start by setting the bottom wheel position as shown in Figure 19.
WHEEL & 1/2 OPTIONAL DRAW STOP The draw stop on the Wheel & 1/2 system can be utilized to customize the feel of the back wall. If you prefer a hard wall, install the peg in the threaded 632 hole in the bottom cam as shown in Figure 19. If you prefer a softer wall and more of a "valley," shoot the wheel without the draw stop installed. The use of any non-Hoyt draw stop will void the product warranty and may damage the product.

the draw length screw and the module fastening screw. Note that the draw length of the top cam is indicated by the number closest to the draw length screw (Figure 23). Ensure both screws are installed and tightened prior to drawing or shooting the bow to prevent damaging the product.
LOCATING YOUR BOW’S SERIAL NUMBER The seven-digit serial number on all aluminum Hoyt compound bows is located on the riser between the top limbs and under the pocket. (See fig 24) To find the serial number on magnesium bows, look at the rest mount surface. (See fig 25) If you have already attached a rest to your riser, you may have to remove it to see the serial number.
TUNING YOUR BOW There are numerous methods you can use when tuning your Hoyt bow. Hoyt recommends working closely with your local pro shop when tuning your bow to ensure best results. For detailed tuning information, download Easton’s tuning guide at www.eastonarchery.com/downloads. BROADHEADS Most archers discover that they must make slight tuning adjustments when switching from practice points to broadheads (even at the same weight). Broadheads create a dramatic aerodynamic change in arrow flight.
You must have the following items in order to obtain warranty work: 1. A dated proof of purchase (sales receipt). 2. Products must be purchased through a Hoyt authorized dealer (no exceptions!) 3. All compound bows must have a serial number. (See page 26 for information on serial number location) Buying a Hoyt bow over the Internet voids all warranty.
Before any bow is returned a Return Authorization Number must be obtained through an authorized Hoyt pro shop. Bows returned to the factory without a Return Authorization number will be sent back. Do not send accessories with bow unless otherwise instructed to. Write the RA number on the outside of the shipping box and send the Hoyt bow requiring factory service to: Hoyt 543 N.
