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
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
death.

2. DO NOT smoke while operating the machine.
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. 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.
3. ALWAYS keep the machine clean and labels legible. Replace all missing and
hard-to-read labels. Labels provide important operating instructions and warn of
dangers and hazards.
4. ALWAYS check all external fasteners at regular intervals.
5. ALWAYS handle blades carefully. The blades can develop sharp edges which
can cause serious cuts.
6. 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 3 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

STARTING ENGINE
1. Turn engine switch to “ON”.
2. Choke engine if necessary (you may not need to choke a warm engine).
3. Pull starter rope repeatedly until engine starts.
4. If choke was moved to the closed position to start, gradually move it to the open
position as the engine warms up.
5. 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 electric valve
Warning! Always stop the engine before:
1. Cutting electric.
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.

Tel:[phone] www.mastermachinerys.com

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.
