Always refuel in a well ventilated area.
Make sure to stop the engine and wait until the engine cools down when refueling.
Select a flat surface area with no flammable material around for refueling. Be careful
not to spill the fuel. Wipe off well if there is any spill.
Never put fire near the machine during refueling. (Especially, be careful about
smoking.)
If you fill to the top of the fuel tank inlet, fuel might spill out from the tank, and it
becomes dangerous
After refueling, tighten the tank cap well.
Do not run the machine in an unventilated location, such as indoors or inside a tunnel.
The exhaust gas from the engine contains toxic gases such as carbon monoxide and
is very hazardous.
Do not operate the machine near open flames.
Check the clamping condition of each part. Cause the big failure that does not think
that a screw loosens by vibration. Tighten the screw well.
Confirm that the diamond blade does not have anomaly such as deficit of the blade
chip or the crack of the board.
If the machine were not run more than 3 months, be sure to start at low speed in a
few minutes to warm up thoroughly,
for the reason to avoid engine seizure by oil film shortage.
When starting and working with the machine, confirm that neighboring people and
obstruction are safe.
Always pay attention to foothold and work in easy position that allow to keep your
machine in good balance.
Be careful not to touch muffler and engine body as it becomes hot in operation or just
after operation.
Discontinue operation promptly whenever your machine goes deficient or you notice
any abnormality.
Be sure not to make the cutter with blade stand-by for work.
In the case to be without avoidance, be sure to run the engine at low speed possibly
in a short time.
(In case of running the engine at high speed at the above position for long time, it
might occur the engine seizure by oil film shortage.)
Be sure to stop engine before leaving the machine. Also shutdown engine for
transporting the machine, and close the fuel cock.
Mount blade cover by all means, and use it.
Because engine turns blade when start, be careful enough. Do not bring legs close
especially.
Be careful enough so that be not rolled up your hand or clothes in reel (inside of the
belt cover).

When you use machine on inclined area, various risk is accompanied. Adhere
rigidly to the following precautions to a minimum, and try for further safety
retention. When you cannot get safety, never use it.
Do not leave machine in the inclined area. There is danger to cause a serious
accident when machine begins to move by any chance.
In the inclined area, grasp a handle well, and never separate a hand from machine.
Machine begins to move in tare weight at the moment when you separated a hand,
and there is danger to cause a serious accident.
Because there is the danger that machine runs uncontrollably when a grip falls out
from the handle, warn you enough.
When you work in inclined area, be located in the upper part of the slope for machine
by all means, and let machine face straight it below for a slope, and work.
When put ring stopper, never go in the front side of the machine. When machine has
begun to move by any chance. There is the danger of serious injury or decease, by
the physical truncation with blade and the conflict of machine.
If hand touches the blade when put ring stopper, there is danger injured seriously. Put
ring stopper from the non blade cover side of the machine by all means.
In case of stop, when water is in the water tank, the center of gravity rises and the
balance worsens . Even if you put ring stopper to the front wheel at the time, it is very
dangerous that the front wheel climbs over ring stopper and begins to move. In this
case pull water out of the water tank by all means.
When a road surface gets wet in inclined area, ring stopper in itself slips depending
on an angle, and effect is gone. Stop on the dry road surface by all means, when you
stop it in inclined area out of necessity.
Do not work on blade installation disassembly in inclined area, because it is
dangerous.
Do not work on to cross the slope. There is danger that tumble of the machine or the
damage of the blade cause a serious accident.
Be sure to work with sling by crane license holder.
Before work of lifting, check any damage of body parts (especially, Lifting hook, etc)
or looseness / omission of screws, and be sure safe.
Stop the engine at the time of the lifting, and close the fuel cock.
Use enough strength of wire rope.
The work of lifting uses only one-point lifting hook, and do not lift in other point
(handles).
Never put any person or animal under the lifted machine.
For safety, do not lift up the machine more than required height.
Stop the machine at flat space. When you stop machine in
inclined area out of necessity, lower straight machine after
having stopped the engine by all means, do ring stopper to the
front wheel for safe retention by all means. When be collided by
an automobile and be shaken in right and left, even if you put on
ring stopper down the front wheel, the machine climbs ring
stopper and begins to move, and be careful this risk is very likely.
Even if you put on ring stopper down the back wheel, there is not
effect. In addition, a parking brake of the rear wheel is not a thing
to guarantee certain fixation of the machine. Use ring stopper for
a front wheel on the occasion of a stop by all means.

Stop the engine at the time of transportation.
Carry it after engine and body got cold well.
By all means drain fuel before transporting the machine .
Fix the machine well not to move and fall down.
Appropriate maintenance is always required for safety operation and to maintain
performance of the machine. Pay full attention in the condition of the machine, and
maintain good condition. Especially improper maintenance of lifting-related part
becomes cause of serious accident.
Do work after lower temperature of machine. Especially muffler becomes high
temperature, and there is danger that burn itself. In addition, be careful not to burn
itself enough, because engine or engine oil become hot.
Do the check alignment in situation that stopped engine by all means. There is badly
injured danger when you are rolled up in a reel.
After maintenance fulfillment, check the installation of safety protection parts and
safety of the machine. Especially, check bolts and nuts thoroughly.
When you do maintenance with dismantlement, refer to maintenance manual
regularly, and work safely.

Engine oil (Fig.1)
With the engine positioned horizontally, check
oil-with oil gauge.
Replenish through filler port as necessary. Use
following oil
(10W-30 is in use when shipped).
SAE#30 (for normal temperature)
SAE#20 (for 10 or lower)
SAE#10W-30
This oil can be used throughout the year
regardless of ambient temperature (up to
ambient temperature -20 䉝㻌).
When it is used in normal temperature, its
consumption tends to increase. Pay additional
attention at the time of daily check. As for quality
of oil, be sure to use SE grade or better.
Degraded quality or decreased quantity may
induce damage by seizure.
Fuel
Use lead-free automobile gasoline. For
replenishment, be sure to shutdown engine and
use strainer provided at filler port. Wipe off any
spilled fuel clean.
V-belt
Check V-belt for any slack or damage. Tension is
proper if the belt bends about 10mm when
pressed with your finger at midway between two
shafts. Retighten as necessary but when
replacing, replace both of them simultaneously.
Place the usable one in stand-by parts. For
adjusting the tension, slide engine longitudinally.
Adjusting the belt
A With 4 bolts removed, take off belt cover.
(Fig.2)
B Loosen 4 engine mounting bolts.
Caution: Bolts should be just loosened;
not removed.
C Rotating it clockwise increases the belt
tension. (Fig.3)

Sprinkling pipe
Open the cock to make sure that sprinkler pipe is not
clogged.
(Fig.4).
Installing the blade:
Disconnect water pipe at the nipple of water tank side.
Remove the blade cover by lifting it upward.
Place flange (IN), diamond blade and flange (OUT)
around the blade shaft in such order, and install
washerbeforetighteningsufficientlywithnut(left-hand
thread). (Fig.5, 6)
Afterinstallingthe blade, replace blade covertobase ,
before replacing water hose to nipple firmly. And
check the cooling water.
Cutting depth adjustment:
To unlock, set the knob to shallow groove.
This will enable you to exactly adjust the cutting depth
by turning the lifting handle.
To lower (feed motion) the machine body, rotate lifting
handle clockwise.
To raise the body, rotate the lifting handle counter-
clockwise.
When decided the cutting depth, set the knob at lock
position for lock the position of machine. (Fig.7)

Cut depth reading method
Cut depth is distance from the reading point of
Fig. 9 to blade tip.
There is blade tip in circumference of blade.
When you cut asphalt or concrete road with
diamond blade, the line trace (trace of line) of turn
happens on the side surface of blade.
Search the line trace of reading point, and read
distance from circumference to it with the scale of
blade cover. (Fig.9)
