    For further reference on the safe operation of skid-steer loaders, Gehl Company suggests that equipment owners obtain the Gehl “Skid-Steer Loader Safety” video, which is available through Gehl dealers. In addition, be sure that everyone who operates or works with this machine, whether family member or employee, is familiar with these safety precautions.
  • Page 10 To ensure safe operation, replace damaged or worn-out parts with genuine Gehl service parts. Gehl skid-steer loaders are designed and intended to be used only with Gehl attachments or approved referral attachments. Gehl cannot be responsible for operator safety if the loader is used with a non-approved attachment.
  • Page 11 During Operation Machine stability is affected by: the load being carried, the height of the load, machine speed, abrupt control movements and driving over uneven terrain. DISREGARDING ANY OF THESE FACTORS CAN CAUSE THE LOADER TO TIP, THROWING THE OPERATOR OUT OF THE SEAT OR LOADER, RESULTING IN DEATH OR SERIOUS INJURY.
  • Page 12 The skid-steer loader has decals that provide safety information and precautions around the loader. These decals must be kept legible. If missing or illegible, they must be replaced promptly. Replacements can be obtained from your Gehl dealer. New equipment must have all decals specified by the manufacturer affixed in their proper locations.
