INSTALLING THE ALTERNATE END-OF-TRAVEL LIMITER
The STAR TRAC INSTINCT LEG EXTENSION can be configured with one of two end-of-travel limiters. The end-of-travel lim-
iter limits the retracted (starting) position of the lower leg pad. You may choose to configure the INSTINCT LEG EXTENSION
with either the large end-of-travel limiter or the small end of travel limiter.
The small end-of-travel limiter configures the unit to accomodate users with less massive legs. When installed, the start-
ing position of the user's feet will be closer to the seat. This leaves less room for ingress and egress, but results in a longer
range-of-motion for the lower leg.
The large end-of-travel limiter allows for easier ingress and egress, but results in a shorter range of motion. The large end-
of-travel limiter is generally recommended for units installed in physical therapy clinics or rehabilitation facilities for use
by "less conditioned" users.
By default, the unit is pre-configured with the small end-of-travel limiter.
Small End-of-Travel Limiter
The end-of-travel limiter is most easily replaced during assembly, prior to performing step 2 (see page 15). When replacing the
end-of-travel limiter on a fully assembled machine, use caution to avoid pinching the fingers during installation. Use a twisting
and pulling motion to remove the currently installed limiter. Use a pushing and twisting motion to install the new limiter.

Insert the belt retainer (36) into the belt clamp. BE SURE the tapped hole in the belt retainer is aligned with the mating
hole in the belt clamp.
CAUTION: BE SURE to keep the weight belt straight when installing the retaining screw (51) in the belt
retainer (36). Misalignment of the weight belt may bias the top plate, which can cause excessive contact of
the top plate shaft with the weights, resulting in excessive noise during use, and potential hazards to the
user or other bystanders.
Thread the retaining screw (51) through the belt clamp and into the belt retainer (36). Tighten the retaining screw to 400
inch-pounds.
Route the weight belt (15) over three pulleys and the leverage arm cam, as illustrated.
Insert the free end of the weight belt (15) through the slot in the leverage arm belt clamp, and pull through the opposite
slot just until force is applied against the top plate (42). This will eliminate any slack in the belt and ensure proper ten-
sioning.
While maintaining tension on the weight belt, press down on the free end of the belt so it lays flat against the inside of
the belt clamp.
Insert the belt retainer (36) into the belt clamp. BE SURE the tapped hole in the belt retainer is aligned with the mating
hole in the belt clamp.
Thread the retaining screw (51) through the belt clamp and into the belt retainer (36). Tighten the retaining screw to 400
inch-pounds.
Check for proper tensioning of the weight belt by applying lateral pressure to the belt at a point midway between two pul-
leys. Deflection of the weight belt should be less than 25 mm. Loosen the retaining screw (51) and adjust belt tension as
needed.
5. Install the Handgrips and Cushion
Brackets
Hold the handgrips (5) in position on the
underside of the main frame (2) and align the
five drilled holes in the handgrips with the
mating holes in the main frame. Secure the
handgrips to the main frame using two screws
(59), four washers (66), two lock nuts (63), one
screw (54), one spring washer (67) and one
washer (66). Tighten the attaching parts
securely.
Hold the seat cushion support (8) in place on
the main frame (2). Secure the seat cushion
support to the main frame using four screws
(52), washers (66) and lock nuts (63). Tighten
the nuts securely.
Hold the back cushion support (7) in place on
the seat post (6) (factory installed). Secure the
back cushion support to the seat post using
two screws (56), four washers (66) and two lock
nuts (63). Tighten the nuts securely.
