STR46SPVG — SILICOSIS/RESPIRATORY HAZARDS
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.

STR46SPVG — GENERAL INFORMATION
STR46SPVG Ride-On Trowel Familarization
The STR46SPVG Ride-On Power Trowel is designed for the
floating and finishing of concrete slabs.
Take a walk around the STR46SPVG Ride-On Power Trowel.
Take note of all the major components like the engine, blades,
air cleaner, fuel system, fuel shut-off valve, ignition switch etc.
Check that there is always oil in the engine, and gear oil in the
gear box assembly.
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
STR46SPVG Ride-On Power Trowels.
Look at the operator control levers. Grab the control levers and
move them around a bit. Look to see how moving the control
levers causes the gearboxes and frame to move.
Notice the foot pedal which controls the engine 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 STR46SPVG Ride-On Power 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
The STR46SPVG 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 from Stow. Please contact your nearest Multiquip
Dealer for a replacement should the original manual disappear.
gearbox assemblies that are enclosed in rugged cast aluminum
gear cases. The main gear is a high quality bronze and steel
composite. The worm gear is composed of hardened steel.
Cooling fins and fans are integrated into the gearbox to provide
maximum cooling for the gearbox oil. The gearbox casing holds
50% more oil capacity than competitors, which allows more
lubrication to be provided to critical points.
Steering Assist
Dual control levers located in front of the operator's seat are
provided for steering the STR46SPVG Ride on Power Trowel.
The control levers are linked to two spring loaded cylinders.
Push the left control lever forward and pull the right control lever
backward and the trowel will rotate clockwise on approximately
a center axis. Pull the left control lever backward and push the
right control lever forward and the trowel will rotate
counterclockwise.
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 training, please use the “TRAINING 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.
Figures 2 and 3 show the location of the controls, indicators and
general maintenance parts. Each control may perform more than
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
