    Echo 1 AK CPM AEG Variable Hop Up System

    By producing a back-spin to the BB bullets, this system allows for straighter and longer distance shooting than normal air gun. Unlike the fixed type, the variable hop up system permits one-touch adjustments using the dial and lever, making it an ideal hop up system.
    Echo 1 AK CPM AEG  Variable Hop Up System Adjustment Procedure (Adjust by carry out trial firing)
    Graduall turn the adjustment dial towards Hop to give hop up to bullets. (The best setting is where bullets fly horizontally.)
    Turning excessively adversely affects the trajectory. So stop turning the hop adjustment lever when bullets fly horizontally.
    Echo 1 AK CPM AEG  Variable Hop Up System The best position is where the bullets fly horizontally, and the longest flying distance is obtained.
    Too much hop-up (return the lever towards NORMAL)

    Straight best position
    Not enough hop-up (return the lever towards NORMAL)

    Echo 1 AK CPM AEG  Variable Hop Up System

    Operational Caution: Strictly observe the following caution)

    Moving the lever too much towards HOP causes bullets to clog. Firing the gun with clogged bullets damages the piston and gears.

    If bullet clogging occurs, immediately stop firing the gun, return the hop lever to the Normal positioning and remove clogged bullets using cleaning rod.

    Make sure to return the hop adjustment lever to the Normal position when removing clogged bullets or cleaning. (Otherwise, the chamber packing is damaged.)

    Never use used or dirty bullets. (Otherwise, the chamber becomes dirty, resulting in unstable hopping up.)

    When about 10,000 rounds are fired, spray silicone oil into the chamber for 0.5 to 1 sec. (See 11 on page 8. The hopping up operation may be unstable for 200 to 300 rounds after spraying the silicone oil, this is the normal operation of the gun.)

    We will not be held responsible for any damage or accidents arising from wrongful operation, disassembly and modification of the gun. Any costs for repair of such damage shall be paid by the user.

    Caution: If the hop-up is adjusted excessively causing clogging of bullets, immediately stop operating the gun. Return the lever to Normal, fire to 2 or 3 shots and readjust.

    Since a precision tight barrel is used, use of dirty bullets or those with burrs causes clogging of bullets and possible fatal damage to the mechanical box and system.

    Warning: Never hold the gun side ways the Bb bullets will curve right or left. This is due to the HOP-UP adjustment.
