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 first 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.
