• 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
• 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 base. 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 base.
• 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 trigger. 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 Projectile Launcher does not need any special maintenance.
• Do not oil the Launcher!
• To store the Launcher in the least amount of space, loosen the thumbscrews and align the barrel parallel to the
base by adjusting the angle to 90°. Tighten the thumbscrews to hold the barrel in place.
Installing the Optional Photogate Bracket (ME-6821A)
The Photogate Bracket is an optional accessory for mounting one or two photogates on the Projectile Launcher to
measure the muzzle speed of the ball.
• Prepare the Photogate Bracket by loosening the thumbscrew near the end of the bracket. Leave the square nut
in place on the end of the thumbscrew. Use the smaller (0.75 in) thumbscrews that are stored on the bottom
side of the bracket to mount one or two photogates to the bracket
