Miscellaneous Installation Information
STM1 Telescoping Manual Mast Installation Notes:
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.)
To minimize elevation errors due to changing cut depths:
a) The mast should be positioned to place the laser receive
The mast should be positioned to place the laser
The mast should be positioned to place the laser
r
as close as possible vertically over the cutting edge of the
blade.
b) The mast should be vertical "front-to-back" when the blade is in
its normal operating position.
To minimize elevation errors due to changing blade tilt on
single laser receiver systems:
a) The mast should be mounted near the center of the
blade.
b) The mast should be vertical "side-to-side" when the blade is in its
normal operating position.
Weld the optional mast mounting plate (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 plate
slightly above a dozer blade. These pieces are not included with
the mounting plate.
Attach the mast to the mounting plate with provided (1) 3/4-
10 x 2-1/2 inch long grade 8 screw and lockwasher. Torque
to 265 ft-lbs. (37 mkg)
Attach the laser receiver to the mast as shown. Wrap the
electrical cable around the mast to keep it out of harm from
blade linkages or material near the blade. Attach the cable
to the laser receiver.
Loosen the mast clamp and extend the mast to the desired
elevation to clear obstructions such as the machines cab.
Tighten the mast clamp.
a) Pull out on the clamp handle to reposition the handle.
