Permobil TiLite CR1 Service Manual
Important Safety Information
Warnings and Cautions
-DO NOT perform any adjustment, removal or installation without rst carefully and thoroughly reading and understanding all of the instructions provided
in this service manual. If unable to perform any tasks in the service manual, seek assistance by contacting a clinician, equipment provider, or contact
TiLite Customer Support.
-The wheelchair is made from carbon ber tubing. While carbon ber is extremely strong, it is imperative that a torque wrench is properly used when
adjusting components clamped around the frame. Improper clamp force can destroy the wheelchair and is not covered under warranty!
-DO NOT use water-based lubricants on or around the front caster and fork or rear wheel axle as they can cause damage to the bearings.
-Only install replacement parts that were manufactured by Permobil.
-Make sure side to side symmetry is maintained when adjusting components of the wheelchair.
-Fasteners with thread patches can be removed and re-installed a maximum of two times before they need to be replaced. If in doubt, use Loctite 242 or
equivalent on the last three threads to replicate thread patch functionality.
-Make sure that all detachable or small parts are handled with care. Keep small hardware components out of the reach of children and any individuals
who have a tendency to place inedible objects in their mouth. Swallowing or inhalation may lead to serious injury or death. IMMEDIATELY seek
emergency medical assistance.

2. 3mm Hex Wrench
3. Torque Wrench
Adjustment:
The CR1 allows for minor adjustment to the center of gravity to fine tune the wheelchair’s feel
and responsiveness to the user’s preference. If an adjustment is desired, follow these steps:
1. Loosen, but do not remove, the bottom clamp screws located at the base of the strut
assembly on both sides.
2. Loosen the frame clamp screws located on the inside of the assembly where the strut
bracket connects to the frame on both sides. It is recommended to undo the rear strap of
the seat upholstery and lift the back portion of the seat sling off of the support straps.
This helps to allow their repositioning after the adjustment to the center of gravity position
is complete.
3. Make the desired adjustment forward or backward.
4. Retighten the frame clamp bracket screws. Torque to 8Nm / 6 ft lbs. It is important to make sure the
left and right strut assemblies are adjusted symmetrically to ensure proper alignment and performance.
If a large enough adjustment is made, it will be necessary to add (if adjusting forward) an additional strut
spacer to both vertical struts to ensure the caster forks remain square. If adding a spacer, it is important to
make sure the strut clamp sits flush with the strut, just below the spacers, to ensure proper tightening of the
strut onto the lower CG Bracket. If a large enough adjustment is made backward, it will be necessary to
remove the existing strut spacer to ensure squareness. To determine if adding or removing a spacer is
required for the desired change to the center of gravity position, please refer to the chart at the bottom of
this page. The extra spacers (2) are included in the Owner’s Packet.
a. If strut spacers were added or removed, make sure the strut clamp is torqued to 4Nm / 3.0 ft lbs.
5. Install the replacement camber tube with camber tube bracket and bottom clamp screws into the strut.
6. Tighten the bottom clamp screws enough to secure the camber tube, but DO NOT fully torque. Check that the
camber tube is centered and that the wheels are properly towed.
7. Progressively torque screws in 2Nm / 1.5 ft lb increments, switching between screws until torque listed in the images below pertaining to type of clamp
on the wheelchair is achieved. If clamp gaps are significantly different, loosen screw on smaller clamp gap side by at least one turn, re-torque opposite bolt
to specified value, then re-torque loosened bolt to specified value. It is acceptable to exceed specified torque value by 2Nm / 1.5 ft lb to achieve better
equivalence in clamp gaps or until clamp gaps are nearly equal.
8. Re-check that the camber tube is centered and that the wheels are properly towed.
