SAFETY INFORMATON
1.3 Blade Safety
Use appropriate steel centered diamond blades manufactured for use on concrete saws.
ALWAYS inspect diamond blades before each use. The blade should exhibit no cracks, dings,
or flaws in the steel centered core and/or rim. Center (arbor) hole must be undamaged and
true. Examine blade flanges for damage, excessive wear and cleanliness before mounting
blade. Blade should fit snugly on the shaft and against the inside/outside blade flanges.
Ensure that the blade is marked with an operating speed greater than the blade shaft speed of
the saw.
Only cut the material that is specified by the diamond blade. Read the specifications of the
diamond blade to ensure the proper tool has been matched to the material being cut.
ALWAYS keep blade guards in place. Exposure of the diamond blade must not exceed 180
degrees.
Ensure that the diamond blade does not come into contact with ground or surface during
transportation. DO NOT drop the diamond blade on ground or surface.
The engine governor is designed to permit maximum engine speed in a no-load condition.
Speeds that exceed this limit may cause the diamond blade to exceed the maximum safe
allowable speed.
Ensure that the blade is mounted for proper operating direction.
1.4 Transportation Safety
Use the lifting bail and appropriate lifting equipment to ensure the safe movement of the saw.
DO NOT use the handle bars and/or front pointer as lifting points.
NEVER tow the saw behind a vehicle.
Ensure that both pointer bars are positioned appropriately to minimize their exposure during
transportation.
Safeguard against extreme saw attitudes relative to level. Engines tipped to extreme angles
may cause oil to gravitate into the cylinder head making the engine difficult to start.
NEVER transport the saw with the blade mounted.
1.5 Service Safety
NEVER lubricate components or attempt service on a running machine.
ALWAYS allow the machine a proper amount of time to cool before servicing.
Keep the machinery in running condition.

OPERATION
2.2 Application
Floor saw has been specifically designed as the ideal machine for the professional contractor
who is engaged in concrete and asphalt flat cutting. It is the most common type of diamond blade
cutting. it is possible to cut both concrete (green or cured, with or without rebar) or asphalt with a
floor saw. Our saw utilized for jobs requiring precision cutting including floors, pavements,
walkways, ramps and other flat sawing applications. This type of cutting is described as “flat”
because the pavement is cut somewhere close to a horizontal plane.
2.3 Operating Principle
The following instructions were compiled to provide you information on how to obtain long and
trouble free use of the unit. Periodic maintenance of this unit is essential. Read the manual in
its entirety and follow the instructions carefully. Failure to do so may injure yourself or a
bystander.
2.4 Assembling the Blade
1. Water hose coupler – Disconnect the water hose coupler.
2. Inner Flange (Collar) – This flange is fixed upon the blade shaft. The inside surface of the
flange must be free of debris and permit a tight closure on the surface of the blade.
3. Diamond Blade – Ensure that the proper diamond blade has been selected for the job.
Pay close attention to the directional arrows on the blade. The blade’s operating
directional arrows must point in a “ down – cutting “ direction to perform correctly. When
placing the blade onto the blade shaft, ensure the arbor hole of the blade matches the
diameter of the shaft.
4. Outside Blade Flange (Collar) – Ensure that the outside blade flange is placed flush
against the diamond blade. The inside surface of the flange must be free of debris and
permit a tight closure on the surface of the blade core.
5. Blade Hex Nut – Unscrew the blade shaft nut, DO NOT overtighten the nut when finalizing
the assembly.
6. Blade Guard – Pull the cover on, tighten the screw beside the blade guard cover
2.5 To Start
1. Turn the throttle control level to the middle position.
2. Set the engine ON/OFF switch to the “ON” position.
3. If it is cold start, turn the choke lever to close position.
4. Grip the recoil starter handle and pull it until you feel slight resistance. Then pull sharply
and quickly. Return the recoil starter handle to the starter case before releasing.
5. Grip the recoil starter handle and pull it a little to feel a slight resistance. Then pull it
powerfully from there. To release the handle do not release it at the position where it has
been pulled to, but release it after returning closely to the starter case.
9
OPERATION
6. If the engine has started, while listening to explosion sounds, return the choke lever slowly
to full-open position. Be sure to perform a warm-up run for the period 3 to 5 minutes at low
speed, while paying careful attention to gasoline leakage or abnormal sound.
7. If it is difficult to start the engine by repeatedly pulling the starter rope, pull off the spark
plug and check the sparking performance. If the plug is wet due to excessive fuel intake or
soiled, replace the coil or clean sufficiently to its internals. With the ignition plug removed,
pull the recoil starter handle 2-3 times to discharge excessive blended gas.
2.6 Cutting
1. Before the saw is placed into operation, run the engine for several minutes. Check for fuel
leaks, and noises that would associate with a loose blade guard covers.
2. Rotate the throttle lever to “rabbit” position.
3. To begin sawing, lower the rotating blade allowing it to cut to the present depth.
4. When blade has reached full cutting depth, slowly walk behind the saw at a rate that will
allow the engine to operate without losing optimum RPM.
5. When the end of the cut has been reached, raise the blade out of the cut by pulling back
on the handlebars (using a downward pressure) until the raise/lower rod drops into its slot
with the blade in the raised position.
6. If cutting is complete, shut the saw down using the following “ To Stop Procedures”.
2.7 To Stop
Stop the engine under normal conditions:
1. Place the engine throttle lever in the slow position, and listen for the engine speed to
decrease. Allow engine to run for 2 or 3 minutes for proper cool down.
2. Turn the engine ON/OFF switch to the “OFF” position.
3. Place the fuel valve lever to the “tortoise” position.

2. Ensure the Engine ON/OFF switch on the engine are turned to the “OFF“ position.
3. Place the PMF14 Saw on a stable level working surface.
4. Ensure the blade is raised and the raise/lower rod is locked into position.
5. Raise the blade by rotating the handlebars
6. Loose the screw, lifting up the blade guard cover to gain access to the diamond blade.
7. Use the provided blade nut and blade shaft locking wrenches to replace the diamond
blade.
8. While holding the blade shaft with the locking Wrench, remove the blade hex nut
(counter-clockwise direction) and outer blade flange.
9. Remove the old blade and install a new blade in the same rotational direction as marked
on the blade.
10. Reinstall the outer blade flange and hex nut. Tighten the nut firmly (clockwise direction).
DO NOT OVER TIGHTEN.
3.2 Blade Guard Check
1. Ensure the capacity of the blade guard matches the diameter of your diamond blade.
2. Check that the guard is bolted firmly upon the saw frame.
3.3 V-belt Alignment and Tension
1. Remove the bolts that secure the V-belt cover to the saw frame.
2. Check uniform parallelism of V-belt and pulley (sheaves). Use a straight-edge or
machinist’s square against both pulleys and adjust both pulleys until equally aligned.
3. DO NOT over or under tighten the V-belt. Severe damage can occur to the saw and engine
crank shaft if the belt is over-tensioned. A decrease of power to the blade and poor
performance will result if the belt is under-tensioned (loose on pulleys).
