1. DISCLAIMER –NO WARRANTY
Due to the unavoidable danger associated with the use of a parachute system, neither the manufacturer of
the canopy nor the manufacturer and/or seller of the harness/container assy makes any warranty, neither
expressed or implied.
Parachuting is associated with great risks and can lead to serious bodily injury or death.
We cannot advise using Slimfit parachutes, unless the user agrees to assume the risks associated with it
and have the appropriate and required training and insight into the use of parachute equipment.
Parachutes can sometimes operate inadvertently, even though they are designed, manufactured, assem-
bled, packed, maintained and used in accordance with all regulations. Malfunctions can result in disability
or death.
Because of the risks associated with the use of parachutes, neither Free Flight Inc, Cahoma Aps nor
Lite-Flite Aps assumes no liability and makes no warranty, either expressed or implied.
Free Flight Inc, Cahoma Aps and Lite-Flite Aps disclaims any liability in tort for damages, direct or conse-
quential, including personal injuries, resulting from malfunction or from defects in design, manufacturing,
materials or workmanship caused by the use of parachute equipment and does not provide any form of
compensation.
The liability of Cahoma and Lite Flite is limited to replacement of defective parts found upon examination by

4. CANOPY INSPECTION
Inspections to be done by a licensed parachute rigger or master rigger only.
Ensure that the canopy is assembled properly according to Cahoma/Lite Flite manual.
Check that the connector links are properly tightened. Never over tightened.
Ensure that steering toggles are installed on steering lines routed through guide rings.
Check for any damage to canopy material or suspension lines.
Canopy and harness/container material is sensible to acid and UV-rays and other violent influence.
Check for any stains or possible soiling by chemicals.
Make sure that no foreign objects are inside the canopy or entangled with lines.
If the assembly fails inspection, it must be removed from service and repaired as described in section 5 or
scrapped.
5. REPAIRS
No major repairs or any alterations are authorized.
If repairs are required, the parachute must be returned to Cahoma/Lite Flite.
Cahoma/Lite Flite will determine further action.
6. ACTUAL USE
After leaving the aircraft, pull hard the chrome opening handle positioned on the shoulder strap at the left
side of the chest.
The canopy is steerable.
By pulling left or right red steering toggles on risers, the canopy can be turned into the wind to optimize the
safest possible landing.
Larger steering effect may be accomplished by pulling the right or left rear riser.
To minimize landing injuries:
- land into the wind
- keep your feet together
- protect your face
- keep your elbows together in front of your chest.
