SAFETY INFORMATION
Introduction
This Safety Alert Symbol is used to call attention
to items or operations which may be dangerous
to those operating or working with this equipment.
The symbol can be found throughout this manual
and on the unit. Please read these warnings and cautions,
along with all decals, carefully before attempting to operate
the unit. Make sure every individual who operates or works
with this equipment is familiar with all safety precautions.
WARNING
GENERAL WARNING. Indicates information
important to the proper operation of the equipment.
Failure to observe may result in damage to the
equipment and/or severe bodily injury or death.
CAUTION
GENERAL CAUTION. Indicates information
important to the proper operation of the equipment.
Failure to observe may result in damage to the
equipment.
Safety Precautions
LETHAL EXHAUST GAS: An internal
combustion engine discharges carbon
monoxide, a poisonous, odorless, invisible
gas. Death or serious illness may result if
inhaled. Operate only in a properly ventilated
area. NEVER OPERATE IN A CONFINED
AREA!
DANGEROUS FUELS: Use extreme caution
when storing, handling and using fuels, as
they are highly volatile and explosive in vapor
state. Do not add fuel while engine is running.
Stop and cool the engine before adding fuel.
DO NOT SMOKE!
SAFETY GUARDS: It is the owner's
responsibility to ensure that all guards and
shields are in place and in working order.
IGNITION SYSTEMS: Breakerless, magneto,
and battery ignition systems can cause severe
electrical shocks. Avoid contacting these units
or their wiring.
SAFE DRESS: Do not wear loose clothing,
rings, wristwatches, etc. near machinery.
NOISE PROTECTION: Wear OSHA specified
hearing protection devices.
EYE PROTECTION: Wear OSHA specified
eye shields, safety glasses, and sweat bands.
FOOT PROTECTION: Wear OSHA specified
steel-tipped safety shoes.
HEAD PROTECTION: Wear OSHA specified
safety helmets.
OPERATOR: Keep children and bystanders
off and away from the equipment.
DUST PROTECTION: Machining, crushing or
handling of stone, concrete, masonry, metal
and other materials may generate dust, mist
and fumes containing chemicals such as
silica, known to cause serious or fatal injury or illness, such
as respiratory disease, silicosis, cancer, birth defects, or
other reproductive harm.
• Control dust, mist and fumes at the source where possible.
Water should be used to control dust whenever feasible.
• Use good work practices and follow the recommendations
of the manufacture, OSHA/NIOSH and other occupational
trade associations.
• When hazards cannot be eliminated the operator and any
bystanders should always wear a OSHA specified respirator
for materials being handled.
REFERENCES: For details on safety rules and regulations
in the United States, contact your local Occupational Safety
and Health Administration (OSHA) office. Equipment
operated in other countries must be operated and serviced
in accordance and compliance with any and all safety
requirements of that country. The publication of these safety
precautions is done for your information. MBW does not by
the publication of these precautions, imply or in any way
represent that these are the sum of all dangers present near
MBW equipment. If you are operating MBW equipment, it is
your responsibility to insure that such operation is in full
accordance with all applicable safety requirements and
codes. All requirements of the United States Federal
Occupational Safety and Health Administration Act must be
met when operated in areas that are under the jurisdiction
of that United States Department.
Safety Decals
Carefully read and follow all safety decals. Keep them in
good condition. If decals become damaged, replace as
required. If repainting the unit, replace all decals. Decals are
available from authorized MBW distributors. Order the decal
set listed on the following page(s).

OPERATION
Introduction
MBW equipment is intended for use in very severe
applications. They are powered by four cycle engines and
are available in different sizes and a selection of engines.
This parts manual contains only standard parts. Variations
of these parts as well as other special parts are not included.
Contact your local MBW distributor for assistance in
identifying parts not included in this manual.
Before Starting & Operating
• REMEMBER! It is the owner’s responsibility to
communicate information on the safe use and proper
operation of this unit to the operators.
• Review ALL of the Safety Precautions listed on page 1 of
this manual.
• Familiarize yourself with the operation of the machine
and confirm that all controls function properly.
• Know how to STOP the machine in case of an
emergency.
• Make sure hands, feet, and clothing are at a safe
distance from any moving parts.
• OIL LEVEL - Check the oil level in the engine. For more
information see “Lubrication” under the respective
engine’s “Owners Manual” or the Maintenance section
of this manual.
• AIR CLEANER - Check to ensure element is in good
condition and properly installed.
• FUEL SUPPLY - The engines on MBW equipment
require an automotive grade of clean, fresh, unleaded
gasoline.
• FUEL FILTER - If clogged or damaged, replace.
Starting Engine
1. Open fuel valve.

6. Move choke lever to open position.
7. Allow engine to warm up for one or two minutes.
Operating
1. Open throttle fully.
2. Compactor will begin vibrating and moving in a
forward direction.
3. Maximum compaction of soil has been reached when
excessive kickback is noticed in the compactor. The
number of passes needed to reach compaction level
desired will depend on soil type and moisture.
4. When using the compactor on asphalt use the water
sprinkling system to keep the plate bottom from
adhering to the hot asphalt.
Stopping Engine
1. Move throttle to idle position.
2. Let engine idle for one or two minutes.
3. Turn switch on engine to “STOP” position.

listed in the Specifications section of this manual.
Refer to the engine owner’s manual for procedure on
setting operating speed if necessary.
2. The idle speed of the engine must not exceed 1800
rpm. If the idle speed is greater the clutch may not
disengage. Check engine owner’s manual for
procedure on setting idle speed.
Cleaning Plate
Remove any excess debris which may get into the housing
of the unit.

Checking Exciter Oil
WARNING
Exciter and oil in exciter is hot after machine has
been running.
These instructions are written for a GP3000. The procedure
for a GP3000-15 is very similar.
Reference the figure on page 12.
1. Let exciter cool before changing exciter oil.
2. Remove the belt guard (#5) and v-belt (page 18, #3).
3. Remove the bolts (#29) that hold the deck (#2) to the
housing (#1).
4. Lift entire deck with engine from housing.
5. Remove pipe plug (page 16, #23) on top of exciter.
6. Rotate exciter shaft so a metal dip stick kind can be
inserted into exciter (see Figure 1).
7. The oil level should be between 7/8” to 1” deep on
bottom of exciter (see Figure 1).
8. If oil needs to be added refer to Fluid Levels, page 6
for the type of oil to be used.
9. Reinstall pipe plug.
10. Reinstall deck, v-belt and belt guard.
Changing Exciter Oil
WARNING
Exciter and oil in exciter is hot after machine has
been running.
These instructions are written for a GP3000. The procedure
for a GP3000-15 is very similar.
Reference the figure on page 12.
1. Let exciter cool before changing exciter oil.
2. Remove the belt guard (#5) and v-belt (page 18, #3).
3. Remove the bolts (#29) that hold the deck (#2) to the
housing (#1).
4. Lift entire deck with engine from housing.
5. Remove drain screw (page 16, #19) and brass
washer (page 16, #22) from the rear cover (page 16,
#9).
6. Tilt housing upside down so oil drains from exciter
(#3). (Examine oil for metal chips as a precaution to
future problems.)
7. Tip housing upright and replace drain screw and
brass washer.
8. Remove pipe plug (page 16, #23) on top of exciter.
9. Fill exciter according to Fluid Levels, page 6.
10. Reinstall pipe plug.
11. Reinstall deck, v-belt and belt guard.

SERVICE
Assembly and disassembly should be performed by a
service technician who has been factory trained on MBW
equipment. The unit should be clean and free of debris.
Pressure washing before disassembly is recommended.
• Prior to assembly, wash all parts in a suitable cleaner or
solvent.
• Check moving parts for wear and failure. Refer to the
Replacement section in this manual for tolerance and
replacement cycles.
• All shafts and housings should be oiled prior to pressing
bearings. Also, ensure that the bearings are pressed
square and are seated properly.
• All bearings should be replaced when rebuilding any
exciter or gearbox.
• All gaskets and seals should be replaced after any
disassembly.
