Before drilling holes in box, make sure there is enough room
for tarp to roll up around tarp axle. Measure box and compare
measurements with those shown.
NOTE: Install mounting brackets directly across from each
other, in line on opposite sides of box/cab guard.
STEP 1: Determine tarp axle mounting location on cab pro-
tector. Location must keep spring-loaded arms from
interfering with cab doors and exhaust stacks. Arms
must not interfere with loading process.
STEP 2: Prepare to cut holes to mount electric motor and axle
bearing. At desired location on each side of cab protec-
tor, measure down 2" from top of cab protector side
rail and mark location for center of tarp axle. Center of
motor shaft hole and axle bearing hole must be aligned.
