TRANSPORTING THE PASSENGER DOWN STAIRS - CONTINUED
7 . Both operators - Maintaining the angle, guide the Stryker
Evacuation Chair over the edge of the stairs, allowing the Stair-
TREAD™ system to engage the first step .
8 . Both operators - Glide down the stairs until the treads are level
across the edges of two or three steps .
9 . Head end operator - Apply slight downward pressure on the
extendable upper control handle while the foot end operator
applies slight upward pressure on the foot end lift handles to
keep the chair from rocking forward as it glides down the stairs .
WARNING
• The Stair-TREAD™ system may not work the same on all
stair surfaces and in all environmental conditions . Based on
conditions, varying amounts of resistance may be encountered .
Avoid getting dirt or other obstructions inside the tracks . Water, ice
and/or debris on the stairs can affect operator footing and proper
operation of the Stair-TREAD™ system . To avoid injury, clear the
path or consider an alternate route . Condensation, water, ice and/
or debris on the Stair-TREAD™ system can cause unpredictable
performance, resulting in a sudden change in the weight the
operators must support .
• To avoid injury, and to aid proper operation of the Stair-TREAD™
system, ensure the belts are clean and dry before transporting the
passenger .
• To avoid injury to the operators and/or the passenger, operators
should never attempt to transport passenger loads greater than
what they can safely lift .
10 . Foot end operator (if necessary) - when the track reaches the
last step, release the front handles . Head end operator - allow the
chair to tip forward until all four wheels are on the ground . Roll
the chair as described on
11 . To fold the Stair-TREAD™ system, pull the red track release bar
toward the black cross bar and fold the track up toward the chair .
Verify the Stair-TREAD™ system is locked in place .
CAUTION
Release the red track release bar before clicking the Stair-TREAD™
system into the locked position . Failure to follow this procedure could
result in the track failing to lock . Always verify the Stair-TREAD™
system is locked by trying to fold it before descending stairs .
If, while descending the stairs, either operator needs to pause or rest,
tilt the chair forward just enough to allow the rear wheels to rest in
the crook of the stair . To continue down the stairs from the resting
position, the head end operator exerts slight downward pressure on
the upper control handle while the foot end operator provides slight
upward pressure to tilt the chair back and engage the Stair-TREAD™
system .
