Tension Adjustment; Removal And Replacement - Garaventa STAIR-TRAC SA-2 Owner's Manual

Tension Adjustment

Removal and Replacement

At a point halfway between the Idler
Roller and the Drive Roller, press down
firmly with your hand. At the closest
point the track cogs should be 70mm
3mm (2 3/4 in 1/8 in) away from the
part of the Drive Frame. You'll note that
tracks will touch the motor housing, but
is taken into consideration in the
measurements. Check and adjust each track to obtain this measurement.
To adjust tension use two 19 mm
wrenches to slightly loosen the rear
axle. Then use a 17 mm wrench and a
5 mm allen key to loosen the Tension
Locking Nuts and turn the Tension
Adjusting Screw; clockwise to increase
tension, or counter-clockwise to
decrease tension.
When decreasing tension, after turning the Adjusting Screw, press down on the
tracks to remove any slack in them and to relocate the rear axle.
Wear on Stair-Trac's tracks should be minimal and track life will be determined
by natural environmental conditions. The tracks contain hundreds of steel wires
to eliminate any possibility of stretching, and are covered by a thick coat of
rubber. They are very durable, but should be replaced if they are cut or cracked
in any way, or show signs of deterioration.
