GENERAL INFORMATION

The MQ Whiteman Power Buggy, Models WBH16 (recoil
start) and WBH16E (electric start) are intended for the
transportation of concrete, concrete spreading and spot
pouring. In addition, the WBH16/WBH16E is designed for
landscaping applications, material sub-base distribution,
job site cleanup and material transport.

The Power Buggy is equipped with a 6-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 5.5-gallon fuel tank allows for
extended uninterrupted use. Maximum speed of the power
buggy is rated at 7.25 MPH.

The maximum weight capacity of the Power Buggy is 2,500
lbs. (1,136 kg). The outer wheels can be removed to allow
the buggy to pass through a 32 in. (81.28 cm.) door.

Hand and foot controls are provided for ease of dumping
and stopping of the WBH16/WBH16E. Multiple lift points
have been provided to allow for easy access of a forklift
when lifting is required.

The WBH16/WBH16E is powered by a HONDA GX390
air cooled gasoline engine rated at 11.7 HP at 3600 RPM

The engine drives a variable displacement hydrostatic
transmission which is activated by a cable controlled
hand lever. The hydraulic fluid flows to a divider valve
which directs the fluid to the forward reverse and dumping
systems.

The operator controls the forward and reverse machine
travel by manually shifting the control valve which directs
the hydraulic fluid flow to the two drive wheel motors. The
flow to the dump cylinder is also controlled by a manually
operated control valve.

This hydraulic system uses a parallel loop configuration,
operating at a maximum of 1450 PSI. The system also
features a neutral position which allows the power buggy
to be moved in the event of an emergency.

The hydraulic oil is filtered by a screen type filter located in
the hydraulic tank, then doubled filtered within the system
by a 10 micron cartridge spin-on return filter.

WARNING

All operators must have training before operating the
WBH16/WBH16E. 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.

of about 1/32" to 1/16". If the wheels are creeping,
turn the adjusting bolt in very slight increments. If
wheels are creeping in reverse, turn the adjusting bolt
counterclockwise. If wheels are creeping forward, turn
the adjusting bolt clockwise.

TIRES/WHEELS/LUG NUTS

Tires and wheels are very important an

d critical components of the buggy. When specifying or
replacing the wheels, it is important that the wheels, tires,
and axle are properly matched.

CAUTION

Table 4. Tire Wear Troubleshooting

LUG NUT TORQUE REQUIREMENTS

It is extremely important to apply and maintain proper wheel
mounting torque on the trailer. Be sure to use only the
fasteners matched to the cone angle of the wheel. Proper
procedure for attachment of the wheels is as follows:

1. Start all wheel lug nuts by hand.

2. Torque all lug nuts in sequence. See Figure 25. DO
NOT torque the wheel lug nuts all the way down.
Tighten each lug nut in 3 separate passes as defined
by Table 5.

DO NOT attempt to repair or modify a wheel. DO NOT
install an inner tube to correct a leak through the rim.
If the rim is cracked, the air pressure in the inner tube
may cause pieces of the rim to explode (break-off) with
great force and can cause serious eye or bodily injury.

TIRES WEAR/INFLATION

Tire inflation pressure is the most important factor in tire life.

1. Check tire pressure when the tires are cold before
operation.

2. Do not bleed air from tires when they are hot.

3. Check inflation pressure weekly during use to ensure
the maximum tire life and tread wear.

4. Refer to Table 4 (Tire Wear Troubleshooting) to pinpoint
the causes and solutions of tire wear problems.
