Outrigger Wheel Assembly: (Optional)
Outrigger wheel assembly (Figure 5) is designed to al-
low the drum to follow the contour of the slab. Wheels
are aligned with cutting drum to follow highs and lows
of the slab removing a consistent depth over the entire
surface. Can be used with all accessories but highly
recommended for diamonds and heavy duty roto peen,
removing traffic lines or thin coatings.
Do Not Bottom Cutter Assembly
If front wheels are not in contact with slab surface when
planing you are bottoming the cutter head. You are riding
on the drum & cutter wheels. Cutter wheels will wear
uneven or break if this is continued. (Figure 6)
Re-adjust depth - turn fine adjustment in “up” direction
until cutters are free and cutting is being accomplished
by “hammering” action only.
Failure to follow these instructions will cause undue cut-
ter wear, breakage, bearing failure or excessive vibration
that will be transmitted back to the machine frame and
engine eventually causing a virtual self-destruction of
the unit.

Cutter Wheel
Uneven wear on cutter wheel
caused by cutting too deep or
cutting very hard concrete
“Full Up Position”
Cutter wheels raised from surface for preparation in starting
engine or to stop cutting operation. (Figure 7a)
“Pre-selected Depth”
Depth of cut determined by the hardness of the surface. Cutter
wheels should swing free on shaft.(FIgure 7b)
“Bottomed Out”
This can cause severe damage to equipment or cause cutters
to flatten or break. (Figure 7c)
Cutter wheels are jammed or forced up against shaft by trying
to remove too much in one pass. Wheels are raised from the
surface and front rides on the drum flanges.
