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 an area with proper
ventilation. 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.
DUST PROTECTION: Wear OSHA specified
dust mask or respirator.
OPERATOR: Keep children and bystanders
off and away from the equipment.
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).

2. Apply moderate thumb pressure to belt about half
way between pulleys. When properly adjusted the
belt should deflect approximately 3/8” (9mm). If the
belt is adjusted correctly reinstall belt guard and
hardware.
3. To adjust belt tension loosen (do not remove) the (4)
engine bolts.
4. Push engine towards the back of the plate. While
holding pressure on the engine retighten the (4)
engine bolts.
5. Recheck belt tension as described in step 2 and
readjust if necessary until the proper tension is
reached.
6. Reinstall roll cage assembly.
Checking Exciter Oil
WARNING
Exciter and oil is hot after machine has been
running. Allow machine to cool before servicing
unit.
1. Let exciter cool before checking oil.
2. Place plate on a level surface.
3. Remove roll cage assembly by removing (4) flange
screws securing roll cage to engine deck. If machine
is equipped with water tank disconnect hose from
spray bar on front of plate. Now entire roll cage
assembly, including roll cage, handle, water tank and
belt guard, can be removed (see Figure 1).
4. Clean all dirt and debris from exciter to prevent
contamination of exciter oil.
5. Remove pipe plug from top of exciter housing.
6. Rotate exciter shaft so a metal dip stick can be
inserted into exciter (see Figure 2).
7. Place a clean metal rod through the oil fill hole as
shown in figure 2.
8. Exciter should have approximately 3/4” (2000 plate)
7/8 to 1” (3550 plate) oil.
9. If oil need to be added, refer to Fluid Levels page of
this section for type of oil to be used. DO NOT
OVERFILL, over filling can cause excessive heat in
exciter.
10. Apply pipe sealant to pipe plug and reinstall into top
of exciter housing.
11. Reinstall roll cage assembly and re-attach hose to
spray bar.
Changing Exciter Oil
WARNING
Exciter and oil is hot after machine has been
running. Allow machine to cool before servicing
unit.
1. Let exciter cool before changing oil.
2. Remove roll cage assembly by removing (4) flange
screws securing roll cage to engine deck. If machine
is equipped with water tank disconnect hose from
spray bar on front of plate. Now entire roll cage
assembly, including roll cage, handle, water tank and
belt guard, can be removed (see Figure 1).
3. Remove 1/2” hex head cap screws and lock washers
from side of bottom plate. Remove belt and engine
deck assembly. Refer to figure 3
