REMOVING SPARE WHEEL AND TIRE FROM TIRE CARRIER
(M915, M916, AND M915A1)
WARNING
Exercise caution when raising or lowering spare wheel and
tire assembly. All personnel must stand clear during lifting
operations. Should wheel and tire assembly fall over or drop
from lift, serious injury to personnel may result. Failure to
comply may result in injury to personnel. Seek medical
attention in the event of an injury.
Do not touch hot clutch disc when raising or lowering spare
wheel and tire assembly winch brake. Failure to comply may
result in injury to personnel. Seek medical attention in the
event of an injury.
Ensure winch cable drum has a minimum of four full turns
of cable prior to lifting spare wheel and tire assembly.
Failure to comply may result in cable pulling off cable drum
and injury to personnel or damage to equipment. Seek

assembly, you must pull on cable and turn handle in a
counterclockwise direction at the same time. Do not pull out
more cable than needed.
