Aim
• If you have the Launcher mounted on the top position, you can adjust the angle of inclination above the hori-
zontal by loosening the two thumbscrews and rotating the Launcher barrel to the desired angle. Use the plumb
bob and the protractor on the label to select the angle. Tighten both thumbscrews when the angle is set.
• You can ‘bore-sight’ through the barrel at a target, such as the ME-6853 Shoot-The
Target. Look through the back end of the barrel when the Launcher is not loaded.
There are two ‘tripod’ (three-spoke) sights inside the barrel, one at the end of the
barrel and one at the end of the piston (about midway in the barrel). Each sight has a
sighting hole at its center. Loosen the thumbscrews and C-clamp and adjust the
angle and position of the Launcher to align the centers of both sights on your target.
Tighten the thumbscrews and C-clamp when the Launcher is aimed.
Load
• To load a ball in the Launcher when its mounted on the low position, either hold the
Ballistic Pendulum out of the way or rotate the pendulum until the rod is horizontal
and it catches in the component clip on the underside of the yoke.
• Place a ball in the muzzle of the Launcher. NOTE: Always cock the piston with a ball in the piston. You may
damage the piston if you use the ramrod without a ball in the piston.
• Remove the ramrod from its storage place on the edge of the upright. While looking through the range-setting
slots on the top side of the Launcher, push the ball down the barrel with the ramrod until the trigger catches
the edge of the piston at the desired range setting. (The trigger will “click” into place.)
• When the yellow indicator tape on the piston is visible in the mid-
dle range-setting slot, the piston is in the SHORT RANGE position.
When the indicator tape on the piston is visible in the next
range-setting slot (fourth from the muzzle), the piston is in the
MEDIUM RANGE position, and when the tape is visible in the last
range-setting slot, the piston is in the LONG RANGE position.
• Remove the ramrod and return it to the storage place on the edge of the upright.
• When the Projectile Launcher is loaded, the yellow indicator tape is visible through one of the range-setting
slots on the upper side of the barrel. Never look down the barrel! To check whether the Launcher is loaded,
look through the range-setting slots on the barrel.
Shoot
• Before shooting the ball, make certain that no one is in the way.
• To shoot the ball, pull straight up on the trigger string that is attached to the trig-
ger. You only need to pull about one centimeter.
• The trigger will automatically return to its initial position after you release the
string.
Maintenance and Storage
• The Ballistic Pendulum/Projectile Launcher does not need any special mainte-
nance. Do not oil the Launcher!
• To store the Launcher in the least amount of space, align the barrel vertically.
One way is to mount it in one of the two vertical slots. Tighten the thumbscrews
to hold the Launcher in place.
