WBH-16EAWD POWER BUGGY — RULES FOR SAFE OPERATION
■ NEVER touch the hot exhaust manifold, muffler or cylinder. Allow
these parts to cool before
servicing engine or AWD
Power Buggy.
■ The engine section of this AWD Power Buggy requires an
adequate free flow of cooling air. Never operate the AWD
Power Buggy in any enclosed or narrow area where free flow
of the air is restricted. If the air flow is restricted it will cause
serious damage to the AWD Power
Buggy or engine and may cause injury
to people. Remember the power
buggy's engine gives off DEADLY
carbon monoxide gas.
■ HighTemperatures – Allow the engine to cool before adding
fuel or performing service and maintenance functions. Contact

WBH-16EAWD POWER BUGGY — OPERATION AND SAFETY DECALS
Machine Safety Decals
The WBH-16EAWD Power Buggy is equipped with a number of safety decals (Figure 1). These decals are provided for operator
safety and maintenance information. The illustrations below show these decals as they appear on the AWD Power Buggy. Should
any of these decals become unreadable, replacements can be obtained from you dealer.
Figure 1. WBH-16EAWD Power Buggy Decals

PAGE 16 — MQ-WHITEMAN WBH-16EAWD POWER BUGGY — PARTS & OPERATION MANUAL — REV. 5 (01/05/07)
WBH-16EAWD POWER BUGGY — GENERAL INFORMATION
The MQ Whiteman All-Wheel Drive AWD Power Buggy, Model
WBH-16EAWD (electric start) are intended for the transportation
of concrete and material handling.
The AWD 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 the AWD Power Buggy has a
unique tub design that reduces concrete splatter outside the
polyethylene tub (bucket)
A low center of gravity has been incorporated into the power
buggy's design which will provide added safety when
maneuvering the buggy in tight areas. A 5.5-gallon fuel tank
allows for extended uninterrupted use. Maximum speed of the
AWD Power Buggy is rated at 7.25 MPH in standard mode and
6.2 MPH in AWD mode.
.
The maximum weight capacity
drops to 1,100 lbs. (499 kg)
when using single wheels on the
AWD Power Buggy.
NOTE
WARNING:WARNING:
WARNING:WARNING:
WARNING:
All AWD Power Buggy operators must have training
instructions before operating AWD Power Buggy. For your
safety, warnings are on the buggy and in this manual.Failure
to obey these warning can cause severe injury or even
death..
The maximum weight capacity of the AWD Power Buggy is 2,500
lbs. (1,136 kg). The outer wheels can be removed to allow the
buggy to pass a 32 in. (81.28 cm.) door.
Hand and foot controls are provided for ease of dumping and
stopping of the AWD Power Buggy. Multiple lift points have been
provided on the AWD Power Buggy.These lifting points allow for
easy access of a forklift when lifting is required.
The AWD Power Buggy is powered by an Briggs and Stratton
Vanguard air cooled gasoline engine rated at 18 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 AWD Power Buggy drive system is controled by the
AWD/2WD toggle switch, located on the console. This switch
allows the operator to quickly change from standard drive model
(2WD) to All-Wheel Drive mode (AWD). Toggling the switch to
AWD mode supplies power to the 12 volt solenoids and traction
assist switch. When operating in AWD mode, the top speed of
the AWD Power Buggy is reduced to 6.2 MPH.
A Traction Assist button located on the handle allows the operator
to momentarily force hydraulic fluid to both drive motors for
improved traction. Engaging the traction assist system while in
AWD mode provides enhanced traction control by using a
specialized hydraulic circuit.This hydraulic circuit provides equal
power distribution to the front drive motors, greatly improving
performance in poor traction conditions such as sand, mud or
loose gravel. This system should only be used as needed and
for short periods of time to prevent damaging your
AWD Power Buggy.
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 AWD 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.
Understand the operation and features of the AWD Power Buggy
and what conditions it will be operated in. Know the rated load
capacity, speed range, braking and steering characteristics,
turning radius and operating clearances.
Remember that the rain, snow, ice, loose gravel, soft ground,
etc., can change the operating characteristics and capabilities
of the AWD Power Buggy.
Inspect the surface over which you will travel. Look for holes,
drop offs and obstacles. Look for rough spots. Look for weak
spots on docks, ramps or floor. Look for oil spills, wet spots and
slippery surfaces. Look for soft soil, deep mud and standing
water. Watch for anything that might make you lose control or
cause the Buggy to tip over.
When transporting the AWD Power Buggy on a truck or trailer,
know the overall height to avoid contacting overhead obstruc-
tions such as bridges, power lines, etc. Make sure all tie-downs
and blocks are in place and the bucket is completely lowered
and securely latched. If the AWD Power Buggy is to be hauled
by truck, check the truck and ramp capacities.
DO NOT leave the AWD Power Buggy in the vicinity of ovens,
furnaces or radiant heaters. Heat could raise the pressure of the
fuel and open the relief blow-off valve, so that vented gas could
ignite.
See Code of Federal Regulation’s Occupational Safety & Health
Administration (OSHA) 29CFR Part 1910.178 to determine
permissible areas where these Buggies can be operated.
This AWD Power Buggy is equipped with a spark arrestor/spark
arresting muffler and cannot be operated in areas with
flammable or explosive atmospheres. Use of the AWD Power
Buggy in these areas can result in fires and/or explosions which
could result in serious injury or death.
Understand the DANGER, WARNING, or CAUTION safety
signs on the AWD Power Buggy. READ this entire manual
before operating the AWD Power Buggy.

filled with fuel prior to operation. Refer to the manufacturers Engine
manual for instructions & details of operation and servicing.
1. Oil Fill Cap – Remove cap to refill or replace oil with
recommended type as listed in Table 3. Make sure cap is
tightened securely. DO NOT over fill.
2. Oil Dipstick – Remove to check amount and condition of
oil in crankcase.
3. Fuel Pump – Draws fuel from the fuel tank into the engine.
4. Spark Plugs – Provides spark to the ignition system. Set
spark plug gap to 0.70- 0.76 mm (0.028 - 0.030 in.) Clean
spark plug once a week.
5. Electric Starter – Starts engine when ignition key is rotated
to the “ON” position.
6. Oil Drain Plug – Remove to drain crankcase oil.
7. Recoil Starter (pull rope) – Manual-starting method. Pull
the starter grip until resistance is felt, then pull briskly and
smoothly.
8. Throttle Lever – Used to adjust engine RPM speed (lever
advanced forward
SLOW , lever back toward operator
FAST ).
9. Choke Lever – Used in the starting of a cold engine, or in
cold weather conditions. The choke enriches the fuel
mixture.
Operating the engine without
an air filter, with a damaged air
filter, or a filter in need of
replacement will allow dirt to
enter the engine, causing rapid
engine wear.

the fuel system. Release the latches on the sides of the air
filter cover to gain access to filter element.
12. Exhaust Manifold – Used to reduce noise and emissions.
NEVER touch the muffler while it is hot! Serious burns can
result.
NEVER operate the engine with the muffler removed.
13. Oil Filter – Prevents dirt and other debris from entering the
engine. Service the oil filter as recommended in the
maitenance section of this manual.
