Maintenance Schedule
• Before each use, always check for any worn, loose or 
  damaged parts on the MoJack 750XT. If any damaged parts  
  are present, do not use the MoJack 750XT and contact 
  MoJack at 1-877-575-3173.
• Clean and oil the screw thread after every 50 uses or at 
  least once a year using light machine oil.
• Place lithium grease between the Crank Handle Base and 
  the brass bearing after every 50 uses or once a year. 
  Without weight on carrier, lift the Crank Handle to create 
  a small gap between the brass bearing and the Crank 
  Handle Base. Use a small brush to apply the lithium 
  grease between the two surfaces.
• Place lithium grease on or around Screw Thread Bottom, 
  Roll Pin and Screw Thread Bottom Washer after every 50 
  uses or at least once a year.
• Spray grease or lube in Locking Pin holes and shaft after 
  every 50 uses or at least once a year.
• (Optional) Check for Carrier Locking Pin operation. Turn 
  top Crank Handle to raise the Lift Arm to the rst Safety 
  Hole and listen for click as pin pops into hole. After a 
  click is heard, reverse direction of Crank Handle rotation 
  without pulling on the Carrier Locking Pin ring. Pin 
  should hold Carriage at height. Do not force the handle 
  past the lock point, as this may damage the Screw 
 Thread. If Carrier Locking Pin does not hold Lift Arm 
  height, do not use the MoJack 750XT and contact MoJack 
  at 1-877-575-3173. After checking Carrier Locking Pin 
  operation, proceed to lower by pulling out on the Carrier 
  Locking Pin ring.
