LIMITED WARRANTY

Your Booster bow is warranted to be free of defects in materials and workmanship for two full years when purchased from an Authorized Retailer. This warranty includes all bow parts, except the string, buss cable, cable glide and cosmetic appearance.

SAFETY FIRST

In order to ensure your personal safety and the safety of those around you, it is necessary to read, understand and follow all of the warnings and safety guidelines before beginning to use or work on your bow or any other archery equipment used with the bow.

WARNING: This bow is strictly intended for recreational use only.

WARNING: Booster shall not be liable for injuries suffered or caused by misuse, unsafe or improper arrow and bow combinations or for injuries sustained when using an altered or modified bow or by unconventional use.

IMPORTANT SAFETY WARNINGS

WARNING: Never work on or attempt to shoot your bow while on medication or while using drugs or alcohol which may impair judgment, physical abilities or reflexes. Doing so can result in damage to the bow, serious injury or even death.

WARNING: Your bow is a precision instrument. It requires specific care and handling to maintain and achieve maximum performance. Booster recommends that all maintenance and repair of your bow be performed by an authorized retailer. Failure to comply with this warning may void your warranty, cause damage to your bow, serious injury or even death. Booster will not assume any liability if this warning is ignored.

BEFORE SHOOTING YOUR BOW

WARNING: Be sure to take the following actions to carefully inspect the condition of your bow each time before use:

• Inspect the condition of the bowstring and cables.
• Inspect the condition of the string servings, nocking point or string loop.
• Inspect that the limbs, cams and riser are in proper condition and orientation.
• Always keep your bow string and cables waxed.
• Inspect the condition of the arrows, nocks, fletching, arrow rest and bow sight.

GENERAL SAFETY GUIDELINES

Damaged strings and cables will adversely affect the performance of your bow. This can result in further damage to other bow components and may cause serious injury to yourself and those around you. Any damaged bow parts or accessories should be reported to your authorized retailer for inspection or replacement.

WARNING: Always be extremely careful when handling sharp objects around the bow's string and cables. A string or cable that is cut or frayed should be replaced immediately. A cut string or cable can result in instantaneous separation and may cause serious injury to yourself and those around you.

WARNING: NEVER DRY-FIRE YOUR BOW. To dry-fire means to draw and release the bowstring without an arrow nocked to the string. Dry-firing your bow can drastically reduce its life expectancy and can cause immediate damage to the bow and possibly serious injury to yourself and those around you.

WARNING: Always shoot the recommended minimum arrow weight. Do not shoot an arrow weighing less than five grains (0.33 grams) for every pound of draw weight. For example, if your bow is set at 50lbs, do not shoot an arrow weighing less than 250 grains (16 grams). Shooting an arrow below five grains per pound of the bow's draw weight can cause damage to your bow and may cause serious injury to yourself and those around you.

Damage caused by shooting an arrow that is too light will not be covered under warranty. Shooting an underweight arrow has an effect similar to that of a dry-fire and may cause serious injury to yourself and those around you. If unsure about arrow compliance to your bow, contact your authorized retailer or the arrow manufacturer.

WARNING: Shoot arrows with a suitable length to prevent the arrow from falling off the rest when drawing your bow. Always follow the inspection recommendations provided by the manufacturer of your arrows. Immediately discard any dented, split, splintered or otherwise damaged arrows. Replace cracked, damaged or broken nocks. NEVER SHOOT A DAMAGED ARROW. Shooting a damaged arrow may cause serious injury to yourself and those around you.

SHOOTING YOUR BOW

WARNING: ALWAYS BE SAFE!

• NEVER shoot an arrow straight up.
• DO NOT draw the bow beyond its specified draw length.
• NEVER draw or attempt to shoot your bow unless certain that no part of the bow can come into contact with another object during the shooting process.
• NEVER aim or point a drawn bow at another person or object you do not intend to shoot.
• ALWAYS use the correct shooting form to avoid arm injury caused by the string.

TARGET SAFETY AND MAINTENANCE

WARNING: ALWAYS BE SURE OF YOUR TARGET! Make sure that there are no people, animals, buildings, roads or other objects behind or near your target. Ensure that your backstop is large enough to catch a stray arrow and thick enough so that the arrow will not be able to penetrate completely through it. When shooting with others, never retrieve arrows or allow others to retrieve arrows until all arrows have been shot and the shooting lane is clear.

WARNING: STORING AND MAINTAINING YOUR BOW

Never expose your bow to excessive heat or prolonged moisture. Avoid storing your bow for extended periods in places such as a garage, attic, or in the trunk of a vehicle, as this can subject your bow to extreme heat or moisture. This could cause damage to your limbs, strings, and other parts of the bow which may not be covered under the manufacturer's warranty.

If your bow becomes exposed to moisture, ensure it is completely dry before storing. Keep your bow (especially the cams) clean and free from dust. If your bow is wet, dry it using a soft cloth. Do not heat dry.

Avoid the use of solvents, sprays, or cleaners such as mineral spirits or acetone on or around your bow, as these can adversely affect the finish.

Regularly check the condition of screws and bolts, and replace them once they begin to wear out.

DRAW WEIGHT ADJUSTABILITY

You can adjust the draw weight in a range of 15lbs (e.g., 60lbs possible adjustment from 45lbs to 60lbs). Draw weight adjustments can be made by turning the limb bolt clockwise or counter-clockwise using an Allen wrench. It is important to adjust both limb bolts in equal amounts. Do not exceed the recommended turns out from the maximum draw weight.

Maximum opening: 5 complete turns starting from closed position.

Diagram showing the draw weight adjustment mechanism. The limb bolt is shown, with arrows indicating 'decreasing draw weight' (counter-clockwise) and 'increasing draw weight' (clockwise). The limb pocket bolt is also indicated.

BOOSTER DUAL SYNCRO CAM

The BOOSTER XT 38.1 is equipped with a dual 'auto syncro' cam with two cam system options. The draw length adjustability range for cam 1 is from 26.5"-30.5" without a bow press. For cam 2, the adjustability range is from 24.5"-27.5".

To adjust draw length, loosen the fastening screw (red marking), remove the draw length screw (green marking) from the module, and rotate the draw module to the desired draw length hole (see page 10). Reinsert the draw length screw, snug the screw into position, and retighten the fastening screw clockwise (do not overtighten). Repeat this process on the second cam, making sure both modules are set in the same draw length position.
