ANTI-TIPPERS (FIGURE 1)
WARNING
Anti-tippers are an option on this wheel-
chair. Invacare strongly recommends or-
dering the anti-tippers as an additional
safeguard for the wheelchair user.
Anti-tippers must be fully engaged and
spring button protruding out of locking
hole BEFORE using the wheelchair.
Installing the Anti-Tippers
1. Press the release buttons IN and insert the anti-tip-
pers with the anti-tipper wheels pointing toward the
ground/floor into the rear frame tubing until the but-
tons lock in place.
2. Measure the distance between the bottom of the anti-
tipper wheels and the ground/floor.
NOTE: a 1-1/2 to 2-inch clearance between the bottom of
the anti-tipper wheels and the ground/floor MUST be main-
tained at all times.
3. If the distance between the bottom of the anti-tipper
wheels and the ground/floor is not 1/1/2 to 2-inches,
adjust the anti-tippers. Refer to ADJUSTING THE
ANTI-TIPPERS in this section of the manual.
Adjusting the Anti-Tippers
1. Press the spring button on the wheeled portion of the
anti-tipper and slide it up or down to achieve the 1-1/2
to 2-inch clearance.
2. Check to make sure that the spring buttons are fully
engaged in adjustment holes.
