PROPOSITION 65 WARNING
Engine exhaust and some of
its constituents, and some dust created
by power sanding, sawing, grinding,
drillingandotherconstructionactivities
contains chemicals known to the State
of California to cause cancer, birth
defects and other reproductive harm.
Some examples of these chemicals are:
Leadfromlead-basedpaints.
Crystallinesilicafrombricks.
Cementandothermasonryproducts.
Arsenicandchromiumfrom chemically
treatedlumber.
Your risk from these exposures varies,
dependingonhowoftenyoudothistype
of work. To reduce your exposure to
these chemicals: work in aALWAYS
well ventilated area, and work with
approved safety equipment, such as
dust masks that are specially designed
to filter out microscopic particles.

SILICOSIS/RESPIRATORY WARNINGS
WARNING
SILICOSIS WARNING RESPIRATORY HAZARDS
Grinding/cutting/drilling of masonry, concrete, metal and
other materials with silica in their composition may give
off dust or mists containing crystalline silica. Silica is a
basic component of sand, quartz, brick clay, granite and
numerous other minerals and rocks. Repeated and/or
substantial inhalation of airborne crystalline silica can
cause serious or fatal respiratory diseases, including
silicosis. In addition, California and some other
authorities have listed respirable crystalline silica as a
substance known to cause cancer. When cutting such
materials, always follow the respiratory precautions
mentioned above.
WARNING
Grinding/cutting/drilling of masonry, concrete, metal and
other materials can generate dust, mists and fumes
containing chemicals known to cause serious or fatal
injury or illness, such as respiratory disease, cancer,
birth defects or other reproductive harm. If you are
unfamiliar with the risks associated with the particular
process and/or material being cut or the composition of
the tool being used, review the material safety data
sheet and/or consult your employer, the material
manufacturer/supplier, governmental agencies such as
OSHA and NIOSH and other sources on hazardous
materials. California and some other authorities, for
instance, have published lists of substances known to
cause cancer, reproductive toxicity, or other harmful
effects.
Control dust, mist and fumes at the source where
possible. In this regard use good work practices and
follow the recommendations of the manufacturers or
suppliers, OSHA/NIOSH, and occupational and trade
associations. Water should be used for dust
suppression when wet cutting is feasible. When the
hazards from inhalation of dust, mists and fumes cannot
be eliminated, the operator and any bystanders should
always wear a respirator approved by NIOSH/MSHA for
the materials being used.

SAFETY INFORMATION
CAUTION
NEVER allow any person or animal to
stand underneath the equipment while
lifting.
Ride-on trowels are very heavy and
awkward to move around. Use proper
heavy lifting procedures and DO NOT
attempt to lift the trowel by the guard rings.
NOTICE
The easiest way to lift the trowel is to utilize the lift loops
that are welded to the frame. These lift loops are located
to the left and right sides of the operator’s seat.
A strap or chain can be attached to these lift loops,
allowing a forklift or crane to lift the trowel up onto and
off of a slab of concrete. The strap or chain should have
a minimum of 2,000 pounds (1,000 kg) lifting capacity
and the lifting gear must be capable of lifting at least this
amount.
NEVER transport trowel with fl oat pans attached unless
safety catches are used and are specifi cally cleared for
such transport by the manufacturer.
NEVER hoist the trowel more than three feet off the
ground with fl oat pans attached.
Before lifting, make sure that the lift loops are not
damaged.
Always make sure crane or lifting device has been
properly secured to the lift loops of the equipment.
ALWAYS shutdown engine before transporting.
CAUTION
Check with your local county or state safety
towing regulations, in addition to meeting
Department of Transportation (DOT)
Safety Towing Regulations, before towing
your trowel.
In order to reduce the possibility of an accident while
transporting the trowel on public roads, ALWAYS
sure the trailer that supports the trowel and the towing
vehicle are mechanically sound and in good operating
condition.
ALWAYS shutdown engine before transporting

Avoid sharp turns to prevent rolling.
Trailer should be adjusted to a level position at all times
when towing.
Raise and lock trailer wheel stand in up position when
towing.
SAFETY INFORMATION
Place chock blocks underneath wheel to prevent rolling
while parked.
Place support blocks underneath the trailer’s bumper to
prevent tipping while parked.
Use the trailer’s swivel jack to adjust the trailer height to
a level position while parked.
ENVIRONMENTAL SAFETY
NOTICE
Dispose of hazardous waste proper ly.
Examples of potentially hazardous waste
are used motor oil, fuel and fuel fi lters.
DO NOT use food or plastic containers to dispose of
hazardous waste.
DO NOT pour waste, oil or fuel directly onto the ground,
down a drain or into any water source.

GENERAL INFORMATION
HHX RIDE-ON TROWEL FAMILARIZATION
The HHX is designed for the floating and finishing of
concrete slabs.
Take a walk around your trowel. Take notice of all the
major components like the engine, blades, air cleaner,
fuel system, fuel shut-off valve, ignition switch etc. Ensure
engine and gearbox lubricant levels are within proper
operating range and maintain a proper level of hydraulic
fluid in the hydraulic fluid reservoir.
Read all the safety instructions carefully. Safety instructions
will be found throughout this manual and on the machine.
Keep all safety information in good, readable condition.
Operators should be well trained on the operation and
maintenance of the trowel.
Look at the operator Control Joysticks. Grasp the Control
Joysticks and move them around a bit. Observe how
moving the Control Joysticks cause the gearboxes and
frame to move.
Notice the foot pedal which controls the engine and blade
speed. Also take a look at the main driveline of the trowel.
Take note and reference how the belts look, this is the way
the belts should look when adjusted properly.
Before using your trowel, test it on a flat watered down
section of finished concrete. This trial test run will increase
your confidence in using the trowel and at the same time it
will familiarize you with the trowel’s controls and indicators.
In addition you will understand how the trowel will handle
under actual conditions.
ENGINE HHXG5
The HHXG5 Ride-On Power Trowel is equipped with a liquid
cooled 31 HP Vanguard gasoline engine. Refer to the engine
owner’s manual for specific instructions regarding engine
operation. This manual is included with the ride-on trowel at
the time of shipping. Please contact your nearest Multiquip
Dealer for a replacement should the original manual disappear.
GEARBOXES
The HHX consist of two separate gearbox assemblies that
are enclosed in rugged cast aluminum gear cases.
The gearbox casing holds 50% more oil capacity than
competitors, which allows more lubrication to be provided
to critical points.
HYDRAULIC STEERING
Dual palm grip joystick controls located to the left and
right of the operator are provided for steering the HHX.
The joysticks are linked to three hydraulic steering
cylinders located within the frame of the machine. Detailed
explanation of how the joystick controls affect the steering
of the trowel can be found in the Operation section of this
manual.
See the steering chart (Table 3) for infomation on the effect
the steering joysticks have upon the steering direction of
the machine.
CONSTANT VELOCITY JOINTS (CV-JOINTS)
Constant velocity joints insure the efficient transfer of power
to the drive shaft and maintains the timing of the gearboxes
without any chance of slippage.
TRAINING
For proper train ing , plea se us e the “TR AIN ING
CHECKLIST” located in the front of this manual. This
checklist will provide an outline for an experienced operator
to provide training to a new operator.
Figure 2, Figure 3, and Figure 4 show the location of the
controls, indicators and general maintenance parts. Each
control may perform more than one function.
BLADES
The blades of the ride-on power trowel finish the concrete as
they are swirled around the surface. Blades are classified as
combination (10 or 8 inches wide), finish (6 inches wide). The
HHX is equipped with five blades per rotor equally spaced
in a radial pattern and attached to a vertical rotating shaft by
means of a spider assembly.
