Hybrid Cam Timing & Draw Adjustment
- Place bow in double-pull bow
press with the control wheel to the left and the cam to the
right. Do not use
a single-pull or center-pull press. To do so risks damaging the
bow and will void the warranty.
- Adjust draw length using the module
installed on the lower cam. All Pearson bows are shipped from
the factory with attached specification sheets. Use the module
chart on the specifications sheet to determine which module to
use and which of the lettered holes correspond to the desired
draw length. Install mod screw in the correct lettered hole
first, then another in the only other hole that will accept a
screw.
- Then, move the string post on the
upper control wheel to the lettered position matching the letter
on the draw length module. Release pressure on the riser.
- Observe the position of the control
cable in relation to the timing marks on the control wheel and
the buss cable in relation to the timing marks on the cam.
- Increasing the number of twists in
the control cable will have the effect of rotating the control
wheel upward into the string. Increasing the number of twists in
the buss cable will rotate the cam upward into the string.
Correspondingly, decreasing twist will rotate the control wheel
and/or cam downward.
- Increasing or decreasing twist in
the string affects both control wheel and cam rotation equally.
- In general, approximately four
twists will move the control wheel or cam fully from one timing
mark to the next.
The timing can be fine-tuned to the
individual bow to find the best balance of speed and efficiency for
the shooter.

Pathfinder & Sidewinder Cam Timing & Draw Adjustment
- Place bow in double-pull bow
press with the control wheel to the left and the cam to the
right. Do not use
a single-pull or center-pull press. To do so risks damaging the
bow and will void the warranty.
- Adjust draw length using the modules
installed on the top and bottom cams. You will notice that the
modules are labled with the numbers one through eleven. One
equaling the shortest draw, and eleven equaling the longest.
Each position gives you one inch difference in draw. Equaling
ten full inches of total draw length adjustment.
- Draw the bow slowly observing the
cables as they make contact with the back wall of the module at
full draw. If the top and bottom cams reach the full draw
postion simutaneously the bow is timed.
- If one cam reaches the full draw
position before the other you must adjust the twist in the bus
cables in order to time the bow. Take notice to which end is
open (last to reach full draw). If the bottom cam is open, then
add twist to the bus cable connected to the top cam. If the top
cam is open, then add twist to the bus cable connected to the
bottom cam.

Z-7 Cam
Timing & Draw Adjustment
- Place bow in double-pull bow
press with the control wheel to the left and the cam to the
right. Do not use
a single-pull or center-pull press. To do so risks damaging the
bow and will void the warranty.
- To adjust the timing of the Z-7 cam
simply manipulate the bus cable by either adding or subtracting
twist in the cable. Take notice to the timing mark on the back
side of the cam in relation to the bus cable. If you adjust the
mark below the cable this is the smooth positon of the cam. If
you adjust the mark above the bus cable this is the speed
position of the cam. The timing can be fine-tuned to the
individual bow to find the best balance of speed and efficiency
for the shooter.
- With the Z-7 cam draw length
adjustment is easily acomplished (NO BOW PRESS NEEDED). Simply
remove the two screws attaching the module to the cam. Replace
it with the proper module, and reinsert the screws.
- All Pearson bows are shipped from
the factory with attached specification sheets. Use the module
chart on the specifications sheet to determine which module to
use for your desired draw lenght.
