STM1 Mast Installation:
The machine should be positioned on a flat level surface with the blade on the ground. Make sure
that all mast-mounting bolts are accessible with the appropriate tools when the mounting assembly
is complete.
Caution: Before welding turn the master disconnect off and disconnect any computer module.
1. Observe all safety practices recommenced by the machinery manufacturer while installing and
using the mast.
a) Turn off engine and engage parking brake.
b) Rest blade on the ground.
c) Take precautions to avoid lifting or falling injuries. Mast weight is
57 Lbs. (26 kg.)
2. To minimize elevation errors due to changing cut depths:
a) The masts should be positioned to place the laser receivers as
close as possible vertically over the cutting edge of the blade.
b) The masts should be vertical "front-to-back" when the blade is in
its normal operating position.
3. To minimize elevation errors due to changing blade tilt, the masts
should be vertical "side-to-side" when the blade is in its normal
operating position.
4. Weld the optional mast mounting plates (ATI-010766) to best meet
the above recommendations, and:
a) Not interfere with blade movement or linkages.
b) Provide clearance for pin removal, or other service
requirements.
c) Follow all machine manufacturer precautions for welding to the
machine.
d) Several pieces of material are usually required to stand the plates
slightly above a dozer blade. These pieces are not included with the
mounting plate.
5. Attach the masts to the mounting plates with provided (1) 3/4-10
x 2-1/2 inch long grade 8 screws and lock washers. Torque to 265
ft-lbs. (37 mkg)
6. Attach the laser receivers to the masts as shown. Wrap the
electrical cable around the masts to keep it out of harm from blade
linkages or material near the blade. Attach the cables to the laser
receivers.
7. Loosen the mast clamp and extend the mast to the desired
elevation to clear laser obstructions such as the machine's cab.
Tighten the mast clamp.
a) Pull out on the clamp handle to reposition the handle.
