Changing to Machine Operation
Rotate each by-pass valve clockwise and hand tighten
them (torque of approximately 71 in-lb (8 N⋅m))
(Figure 26).
Note: Do not over tighten the by-pass valves.
The machine will not drive unless by-pass valves are
turned in.
Loading Machines
Use extreme caution when loading units on trailers or
trucks. One full width ramp that is wide enough to
extend beyond the end of the tracks is recommended
instead of individual ramps for each side of the unit
(Figure 27). The lower rear section of the machine
frame extends back between the rear wheels and serves
as a stop for tipping backward. Having a full width ramp
provides a surface for the frame members to contact if
the unit starts to tip backward. If it is not possible to
use one full width ramp, use enough individual ramps
to simulate a full width continuous ramp.
The ramp should be long enough so that the angles do
not exceed 15 degrees (Figure 27). A steeper angle may
cause attachment components to get caught as the unit
moves from ramp to trailer or truck. Steeper angles
may also cause the unit to tip backward. If loading on
or near a slope, position the trailer or truck so it is on
the down side of the slope and the ramp extends up the
slope. This will minimize the ramp angle. The trailer or
truck should be as level as possible.
2. Left by-pass valve
Important: Do not attempt to turn the unit while
on the ramp; you may lose control and drive off the
side, or the tracks may come off.
Avoid sudden acceleration when driving up a ramp and
sudden deceleration when backing down a ramp. Both
maneuvers can cause the unit to tip backward.
Loading a unit onto a trailer or truck increases
the possibility of backward tip-over and could
cause serious injury or death.
• Use extreme caution when operating a unit
on a ramp.
• Use only a single, full width ramp; Do not
use individual ramps for each side of the
unit.
• If individual ramps must be used, use
enough ramps to create an unbroken ramp
surface wider than the unit.
• Do not exceed a 15 degree angle between
ramp and ground or between ramp and
trailer or truck.
• Avoid sudden acceleration while driving unit
up a ramp to avoid tipping backward.
• Avoid sudden deceleration while backing
unit down a ramp to avoid tipping backward.
