Lubricate the T-bolt
Terex specifi cations require that this procedure be
performed every 250 hours or quarterly, whichever
comes fi rst.
Maintaining the T-bolt is essential to good machine
performance and safe operation. An unsafe
working condition exists if the T-bolt has excessive
wear and/or does not operate smoothly, free of
hesitation and binding.
1 Using the illustration as a guide, locate the
T-bolt at the bottom of the mast assembly.
Remove the T-bolt from the mast.
2 Remove all dust, dirt and oil residue from the
threaded surfaces of the T-bolt, and apply a few
drops of light oil or thread lubricant onto the
threaded surfaces.
3 Fully install the T-bolt into the mast.

Inspect and Adjust the Brakes
(if equipped)
Axle specifi cations require that this procedure
be performed every 3000 miles or quarterly,
whichever comes fi rst.
Maintaining the axle brakes in good condition is
essential to safe operation and good performance.
Brakes which are out of adjustment can result in
longer stopping distances and excessive brake
wear on the towing vehicle. Component damage
may also result if problems are not discovered and
repaired in a timely fashion.
Note: Perform this procedure with the machine
on a fi rm, level surface with the machine in the
stowed position.
1 Select a wheel. Chock the front and rear of the
tire at the opposite side of the machine.
2 Loosen the wheel lug nuts. Do not remove
them.
3 Place a lifting jack under the axle near the
wheel to be removed. Lift the axle until the
wheel is off the ground and place a jack stand
under the axle. Lower the axle onto the jack
stand and remove the wheel.
4 Remove the dust cap from the hub. Remove the
cotter pin from the castle nut.
5 Remove the castle nut and washer.
