Shock Absorbers (A, A1, A2)
Adjustable shock absorbers are provided when this option is
specified. Shocks dissipate kinetic energy over a wide range
of velocities and weights. Cylinder stroke is adjusted by
moving the threaded stroke adjuster. It is important to
adjust the threaded stroke adjuster to prevent the shock
from "bottoming". Maximum adjustment is 1".
Shock Absorber Adjustment Procedure: Proper
adjustment is important to maximize a shock absorber's
performance. With a range of zero to ten, shocks are factory
pre-set at five. Cycle the slide to impact the shock absorber.
Rotate the shock's adjustment knob to achieve smooth
deceleration. Adjusting towards zero increases resistance.
If the initial impact is too hard, rotate the knob towards ten to
lessen the resistance. If the final setting is less than one, a
larger shock and/or slide should be considered. Tighten the
adjusting knob set screw to maintain resistance.

NOTE: A standard HBBY unit includes mounting holes in the
end plates to allow field installation of the shock absorbers.

If A1 or A2 option is specified, bumpers will be provided in the
opposite direction.

Threaded shock absorbers are included when shock
absorbers are specified.
