ALWAYS inspect the rubber track before each use. Be
sure to check the tension and maintain the prescribed
(regulated) tension.
ALWAYS drive slowly in areas where the road surface is
unstable such as forests, some construction sites, and/or
unpaved roads. High speed in these areas can result in
breakage of the rubber track.
Remove any foreign objects such as tree branches, leaves,
etc. caught between the frame and the rubber track, after
each operation.
lf foreign objects are not removed between the frame and
the rubber track, the gap between the rubber track and
the frame will shorten, and this can make the rubber track
more susceptible to cracks and wear.
Regularly inspect the condition of the sprocket, track
roller, idler, and the imbedded metal guide for abrasion.
Excessive or unusual abrasion or scarring can shorten
the life span of the rubber track.
Enlarge the turning radius when turning and changing
directions, in areas of high friction, such as asphalt, to
avoid premature breakage of the rubber track.
In cases where the job site location is far away, transport
the machine on a fl atbed truck or similar towing vehicle.
Continuous operation over long distances for an extended
period of time is not recommended.
Driving the rubber track through narrow passages on job
sites can fold the edges of the rubber track. Excessive
bending of the track can Iead to breakage.

GENERAL INFORMATION
The MQ Whiteman Track Power Buggy, WTB-16 is intended
for the transportation of concrete, concrete spreading and
spot pouring. In addition, this power buggy is designed for
landscaping applications, material sub-base distribution,
job site cleanup and material transport.
The Power Buggy is equipped with a 10-inch dump height
which provides clearance and enables the operator to
maneuver over any form height. In addition, it has a unique
polyethylene tub design that reduces concrete splatter.
A low center of gravity has been incorporated into the
design which provides added safety when maneuvering the
buggy in tight areas. A 5.0-gallon (20-liter) fuel tank allows
for extended uninterrupted use. The maximum speed of the
power buggy is rated at 5.1 mph (8.2 km/h).
This buggy employs 16-inch-wide rubber tracks to traverse
the terrain. The tracks allow the buggy to travel over soft
ground such as sand and wet surfaces. The rubber track
design increases the overall traction of the buggy.
Hand and foot controls are provided for ease of dumping
and stopping of the power buggy. Multiple lift points have
been provided to allow for easy access of a forklift when
lifting is required.
The WTB-16 model is powered by a Honda GX690
air-cooled, gasoline engine rated at 22 hp at 3,600 rpm.
The operator controls the forward and reverse machine
travel by manually shifting the control levers which directs
the hydraulic fluid flow to the drive motors. The fluid flow
to the dump cylinder is controlled by a manually operated
control valve.
This hydraulic system incorporates a closed loop
configuration operating at a maximum of 4,300 psi (300 bar).
The hydraulic oil is filtered by a screen-type filter located in
the hydraulic tank, then double-filtered within the system
by a 10-micron cartridge spin-on return filter.
WARNING
All operators must have training before operating the
power buggy. For your safety, warnings are on the
machine and in this manual. Failure to obey these
warnings can cause severe injury or even death.
CAUTION
DO NOT attempt to operate the power
buggy until the Safety Information, General
Information, and Inspection sections of this
manual have been read and thoroughly
understood.
The engine drives a variable displacement hydrostatic axial
piston pump.

BATTERY
This unit is of negative ground. DO NOT connect in reverse.
ALWAYS maintain battery fluid level between the specified
marks. Battery life will be shortened if the fluid levels are
not properly maintained. Add only distilled water when
replenishment is necessary. DO NOT overfill.
Check to see whether the battery cables are loose. Poor
contact may result in poor starting or malfunctions.
ALWAYS keep the terminals firmly tightened. Coat the
terminals with an approved battery terminal treatment
compound. Replace the battery with only the recommended
type battery. The battery type used in this power buggy is
BCI Group U1.
The battery is sufficiently charged if the specific gravity
of the battery fluid is 1.28 (at 68°F). If the specific gravity
should fall to 1.245 or lower, it indicates that the battery is
dead and needs to be recharged or replaced.
Before charging the battery with an external electric source,
be sure to disconnect the battery cables.
CAUTION
ALWAYS disconnect the negative terminal FIRST and
reconnect negative terminal LAST.
Battery Cable Installation
ALWAYS be sure the battery cables (Figure 8) are properly
