Maintenance record
Preventative maintenance and routine service plan
This vibratory screed has been assembled with care and will provide
years of service. Preventative maintenance and routine service are
essential to the long life of your Master Vibratory screed. Your dealer is
interested in your new trowel and has the desire to help you get the
most value from it. After reading through this manual thoroughly you will
find that you can do some of the regular maintenance yourself. However,
when in need of parts or major service be sure to see your Master
dealer. For your convenience we have provided this space to record
relevant data about your ride-on Trowel. When in need of parts or
service be prepared to provide your trowel serial number. Locate the
serial number now and record in the space below.
FOREWARD
◇For your own safety and protection from bodily injuries, carefully read, understand
and follow the safety instructions in this manual.
◇Please operate and maintain your machine in accordance with the instructions in
this manual.
◇Defective machine parts are to be replaced as soon as possible.
◇Keep this owner's manual handy, so you can refer to it at any time.
◇No part of this publication may be reproduced without written permission.
◇We expressly reserve the right to technical modifications- even without express
due notice - which aim at improving our machines or their safety standards.
APPLICATION
This screed is a modern, high production machine intended to provide accurate
strike-off of concrete slabs with or without the support of grade stakes or forms. The
vibrations produced by the eccentric weight are equally transmitted along the beam
length and will provide adequate consolidation of unreinforced slabs up to eight

4
inches in depth. Multiple blade lengths and variable exciter weight positions allow
for optimum compaction and production of the slab placement.
SAFETY PRECAUTIONS
1. Before starting operation, the operator has to check that all control and safety
devices function properly.
2. NEVER allow anyone to operate this equipment without proper training. People
operating this equipment must be familiar with the risks and hazards associated
with it.
3. NEVER touch the engine or muffler while the engine is on or immediately after it
has been turned off. These areas get hot and may cause burns.
4. NEVER operate this machine in applications for which it is not intended.
5. ALWAYS wear protective clothing appropriate to the job site when operating
equipment.
6. ALWAYS remain aware of moving parts and keep hands, feet, and loose clothing
away from the moving parts of the machine.
7. ALWAYS operate the machine with all safety devices and guards in place and
in working order.
OPERATOR SAFETY WHILE USING INTERNAL COMBUSTION
ENGINES
Danger! Internal combustion engines present special hazards during operation and
fueling. Read and follow the warning instructions in the engine owner’s manual and
the safety guidelines below. Failure to follow the warnings and safety guidelines
could result in severe injury or death.
1. DO NOT run the machine indoors or in an enclosed area such as a deep trench
unless adequate ventilation, through such items as exhaust fans or hoses, is
provided. Exhaust gas from the engine contains poisonous carbon monoxide gas;
exposure to carbon monoxide can cause loss of consciousness and may lead to

Tel:[phone] www.mastermachinerys.com
5
death.
2. DO NOT smoke while operating the machine.
3. DO NOT smoke when refueling the engine.
4. DO NOT refuel a hot or running engine.
5. DO NOT refuel the engine near an open flame.
6. DO NOT run the engine near open flames.
7. ALWAYS refill the fuel tank in a well-ventilated area.
8. ALWAYS replace the fuel tank cap after refueling.
9. ALWAYS check the fuel lines and the fuel tank for leaks and cracks before
starting the engine. Do not run the machine if fuel leaks are present or the fuel
lines are loose.
SERVICE SAFETY
Warning! Poorly maintained machines can become a safety hazard! In order for the
machine to operate safely and properly over a long period of time, periodic
maintenance and occasional repairs are necessary.
1. DO NOT attempt to clean or service the machine while it is running. Rotating
parts can cause severe injury.
2. DO NOT crank a flooded engine with the spark plug removed on
gasoline-powered engines. Fuel trapped in the cylinder will squirt out the spark
plug opening.
3. DO NOT test for spark on gasoline-powered engines if the engine is flooded or
the smell of gasoline is present. A stray spark could ignite the fumes.
4. DO NOT use gasoline or other types of fuels or flammable solvents to clean parts,
especially in enclosed areas. Fumes from fuels and solvents can become
explosive.
5. ALWAYS keep the area around the muffler free of debris such as leaves, paper,
cartons, etc. A hot muffler could ignite the debris and start a fire.
6. ALWAYS keep the machine clean and labels legible. Replace all missing and

6
hard-to-read labels. Labels provide important operating instructions and warn of
dangers and hazards.
7. ALWAYS check all external fasteners at regular intervals.
8. ALWAYS handle blades carefully. The blades can develop sharp edges which
can cause serious cuts.
9. ALWAYS turn engine off before performing maintenance or making repairs.
OPERATION
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 2 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 engine requires regular grade unleaded gasoline. Use only
fresh, clean gasoline. Gasoline containing water or dirt will damage fuel system.
Consult engine Owner’s Manual for complete fuel specifications.
◇FUEL FILTER - If clogged or damaged, replace.
STARTING ENGINE
1. Turn engine switch to “ON”.

2. Press the primer bulb repeatedly until fuel can be seen in the clear plastic return
tube.
3. Choke engine if necessary (you may not need to choke a warm engine).
4. Pull starter rope repeatedly until engine starts.
5. If choke was moved to the closed position to start, gradually move it to the open
position as the engine warms up.
6. Allow engine to warm up for one or two minutes.
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.
4. Turn off fuel valve
Warning! Always stop the engine before:
1. Adding fuel.
2. Leaving the equipment unattended for any amount of time.
3. Before making any repairs or adjustments to the machine.
Warning! Never run the Screed above idle when the float blade is not in contact
with concrete. This can damage the float blade.
USER SCREED
The Screed can be used with or without forms. The following describes the use of
the Screed without forms.
1. Use a hand float to make a 300-500mm diameter wet pad (A) at the desired
grade in the four corners of the area you wish to screed. The outer extents of
the wet pads should not exceed the length of the float blade being used.
NOTE: Use a laser receiver, transit level, or grade stakes to help establish the
correct grade.

2. Run the Screed between the wet pads to create two parallel strips (B) that define
the grade for the remainder of the wet screeding. These strips should be 300-500
wide.
2. Place one end of the float blade on each of the parallel strips (B) and screed
the concrete (C) in between the strips. Be sure the float blade follows the
contour of the parallel strips

TRANSPORTING
It is recommended to transport the Screed with the float bar removed. The float
bar is more likely to be damaged if attached to the main unit during transport.
STORAGE
The following steps should be taken to prepare your Screed for extended storage.
1. Close fuel shut off valve.
2. Siphon excess gasoline from tank.
3. Start engine until it stops from lack of fuel. This will use up all the fuel in the
carburetor and prevent formation of deposits due to evaporation of fuel.
4. Remove spark plug and pour 2 oz. of SAE-30 or SAE-40 motor oil into the
cylinder. Slowly crank the engine 2 or 3 times to distribute the oil throughout the
cylinder. This will help prevent rust during storage. Replace spark plug.
5. Store the unit in an upright position in a cool, dry, well ventilated area.
