FEATURE
This machine is used of cutting the expansion joint on concrete floor.
Meanwhile, it can cut and groove all standard manufactures of concrete,
marble and granite. It is a necessary machine in the construction of
road. Super-rigid box frame ensures straight cuts while resisting
warping and vibration-prolongs saw life; extends blade life. Height
adjustment handle with comfortable grip handles, easy crank for
raising/lowing cutting depth. Hinged front lift-up blade guard is designed
to provide easy blade replacement; easy-remove, rustless poly water
tank provides an optimum flow and volume of water to the blade. It uses
sheet diamond, which has the virtues of quick cutting speed, and even

cut. Meanwhile, sheet diamond could cut the steal beams in concrete. It
has simply, safety construction, easy and flexible operations.
SAFETY PRECAUTIONS
1. Before starting operation, the operator has to check that all control
and safety devices function properly.
2. To prevent fire hazards and to provide adequate ventilation for
stationary equipment applications keep the engine at least 3 feet (1
meter) away from building walls and other equipment during
operation.
3. Don't allow children to operate the engine. Keep children and pets
away from the area of operation.
4. Know how to stop the engine quickly, and understand the operation
of all controls. Never permit anyone to operate the engine without
prior instructions.
5. Do not place flammable objects close to the engine.
6. The max gradient of 30° must not be exceeded.
7. Wear safety shoes, and eye protection glasses in case of trench
operation where falling sand stones maybe ejected.
8. Keep anyone away from the cutting sheet when the machine
working.
9. It is possible that this cutting machine exceeds the admissible
sound lever of 89 dB (A). According to the rules for the prevention of
accidents regarding emission of noise, the employees have to wear
protection if the sound levels reaches 89 dB (A) or more.
10. Be careful the handle can't keep away of the handle when operate
the machine.
11. Refuel the engine must always be stopped, using all necessary
safety precautions. When refilling fuel tank, do not allow fuel to
come into contact with the hot parts of the engine or spill onto the

Tel:[phone] www.mastermachinerys.com
5
ground.
12. The tank lid must fit tightly. Shut off fuel lever, if available when
stopping the engine. For long distance transports of machine
operated by fuel or fuel-mixtures, the fuel tank has to be drained
completely.
13. Do not smoke or handle open fire near this machine.
SAFETY CHECKS
1. Before install the sheet saw, wipe up hole of the saw and plywood.
2. Keep the cutting blade guard in the bottom most location before the
starting engine.
3. Keep the cutting blade away from roadblock when the starting
engine.
4. Check V-belt tension-retension when the machine working.
5. The cutting blade is in proper condition before starting operation
machine. Keep the machine balanced when the working.
6. Check the water lever when the machine working. Refill the water
tank when the water falling half of the water tank, or straight using
another wellhead to water the cutting blade.
7. To avoid the machine librating from portrait swaying, the main shaft
must be tie in with saw.
8. The sheet diamond is used for cutting bitumen, water concrete
(from 48hrs to 28days), sandstone, sandiness brick, hatchway brick,
and sandiness limestone and so on. Do not cut material as follows:
long-playing water concrete, rigidity brick or harden surface,
savageness stone.
9. Make sure the cutting blade straight cuts forward.

OPERATION
1. Check the cutting blade
1) Check the cutting blade rotate way accord with direction indicator.
2) Check the cutting for arrow and nut tension-retension before start the
machine.
2. Cutting
1) Open the switch of the water tank, and then check water whether it is
spray the blade of side face or not, after filing up in the water tank. Make
sure enough water in tank when operate the machine. Please water the

3) Starting the engine
Be sure to stop the engine prior to refueling.
Do not overfill the fuel tank.
If fuel is spilt, wipe it away carefully and wait until the fuel has dried
before starting the engine. When changing oil, Make sure that the fuel
cap is secure to prevent spillage.
A．Check the oil level and supplies
Level placed gasoline engine, check the oil level, if necessary, oil
supplies
1、Be sure to start the engine prior to check the oil .
Check oil level of machine whether it is between upper and low limit.
Wipe oil spill
2、Oil capacity is 1.65 L

C、running
①Preheat the machine for five minutes at no load .
②Set the speed governor lever of the engine at required speed
position .
③Check ,when the machine is running
a. Whether there is abnormal sound and vibration?
b. Whether combustion is not good or over speed?
c. Whether the color of exhaust gas is normal (black or too white)?
If any of above phenomena is detected, stop the engine immediately
and contact professionals.
3) Andante turn handle, the blade will cut in one spot. The operator can

low cutting depth through turn handle. (turn a handle with a lap the
same as add the cutting depth about 9mm), Keep eyes on guide wheel
forward and hold the handle, and then slowly force on the handle to
make the machine forward. Make sure the cutting blade straight cuts
forward while resting warping and vibration.
NOTICE! You must be stop or slow forward speed at once when the
blade cutting extremely harden roadblock.
3. Stopping the engine
a. Clockwise turn wheel to keep the blade away from work position.
The operator can step on the rod that is fixed on bed plate and then
forcibly downward pressure on the handle if necessary the cutting
stopping.
b. At first set the speed governor lever at low speed position before
stopping the engine ，and then run the engine at no-load for five
minutes.
c. Set the speed governor lever at “stop” position ，Do not stop
engine with decompression lever.
d. Set the fuel cock at “s”（stop position）
e. Pull out the recoil handle slowly until pressure is felt by you hand
(that means at the point of compression stroke，where the intake
and exhaust valves are closed)and then let the handle back to its
natural position so that it can prevent rust when the engine is not
used.

compression stroke, where the intake and exhaust valves are
closed, which can prevent engine from rust.
5、Clean out machine oil and dirt from the engine, and to put the
engine at a dry place.
PARTS SERVICE
V-belt
Check V-belt tension-retension at every week. The correct operation:
Release bolts and nuts that they are setting engine, remove the engine
to V--belt tension, and then tighten nuts.

Disassembly blade
Change the cutting blade with the engine stopped. Remove two bolts
that are setting the protective hood, and then rotate protective hood.
You need to use wrench lock the main shaft to prevent it from
circumgyrating before clockwise sense remove the nut (Leftl). Clean the
blade from dust and dunghill after the finish operation. Check the cutting
blade whether it is normal use or not.
Assembly blade
Check new blade
Make sure the same new cutting blade of style as primary blade. Refer
to the blade of style, please see operation manual.
NOTICE! Please pay attention to the blade rotate way accord with
direction indicator. Clean the blade and check the blade stability after
assembly the blade, and then screw the nut.
TRANSPORT
Do not place the cutting blade on the ground, to avoid possible
damages during transport of the same. To protect the cutting blade,
swing the blade its maximum upward position by way of the height
adjustment/cutting depth adjustment and lower down the protective
hood as far as possible. If need be, take off cutting blade from protective
hood.
When being transported on vehicles protective hood have to be
secured against rolling, slipping or overturning.
ATTENTION! The engine must be stopped when using the integrated
transport device. Lubrication of the engine is not guaranteed if the
engine is running when the cutting is in transport position. This could
lead to serious engine damages. Furthermore the danger exists that oil
will spill out of the crankcase breather.
