c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging
the power tool.
Keep cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for
outdoor use.
Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a residual
current device (RCD) protected supply.
Use of an RCD reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use common sense when operating a
power tool.
Do not use a power tool while you are tired or under the influence of drugs,
alcohol or medication.
A moment of inattention while operating power tools may result in serious personal
injury.
b) Use personal protective equipment. Always wear eye protection.
Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the offposition before
connecting to power source and/or battery pack, picking up or carrying the
tool.
Carrying power tools with your finger on the switch or energising power tools that have
the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on.
A wrench or a key left attached to a rotating part of the power tool may result in
personal injury.
e) Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair,
clothing and gloves away from moving parts.
Loose clothes, jewellery or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used.
Use of dust collection can reduce dust-related hazards.
4) Power tool use and care
a) Do not force the power tool. Use the correct power tool for your application.
The correct power tool will do the job better and safer at the rate for which it was
designed.
b) Do not use the power tool if the switch does not turn it on and off.
Any power tool that cannot be controlled with the switch is dangerous and must be
repaired.

a) Always keep your hands from the cutting area and the diamond saw blade.
If you hold the cutter with both hands, you will not be cut by the diamond saw blade.
b) Do not touch the space below a workpiece.
The fixed guard cannot protect the diamond saw blade below the workpeice.
c) Always use a diamond saw blade with well matched size and axis shape (diamond-
shaped or round).
Poor matching between the diamond saw blade and the clamping part of the cutter may
result in an eccentric operation and further loss of control.
d) Do not use any washers or bolts that are damaged or have incorrect sizes.
This may result in loss of control.
PRECAUTIONS ON USING CUTTER
1. Do not use any cutting tool other than a diamond wheel.

APPLICATIONS
○ Cutting and scribing of concrete.
○ Cutting and scribing various types of stones.
○ Cutting and scribing various types of tiles.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms to the power requirements specified
on the product nameplate.
2. Power switch
Ensure that the power switch is in the OFF position. If the plug is connected to a receptacle
while the power switch is in the ON position, the power tool will start operating immediately,
which could cause a serious accident.
3. Extension cord
When the work area is removed from the power source, use an extension cord of sufficient
thickness and rated capacity. The extension cord should be kept as short as practicable.
4. Mounting the diamond wheel
For details, refer to the item “Mounting and dismounting the diamond wheel”.
5. Confirm that the cutting depth adjusting lever is securely clamped.
6. Cutting depth adjustment (Fig. 1)
Lowering the lever will loosen and raising it will
tighten. Loosening the lever and moving the
base will allow adjustment of the cutting depth.
CAUTION
○ Leaving the lever loosened may result
in injury. Securely tighten the lever after
adjusting the cutting depth.
○ When the cutting depth exceeds 20 mm,
concrete, and so on must be cut in two
steps. Never try to cut in one step;
otherwise, the motor is liable to be overloaded and damage may result. Also,
cutting efficiency will be lowered in such an instance.
MOUNTING AND DISMOUNTING THE DIAMOND
WHEEL

(2) As shown in Fig. 2, the concave portions of
washers (A) and (B) must be on the
diamond wheel side.
(3) Thoroughly clamp the bolt.
2. Dismounting the diamond wheel
Use the provided wrench and box wrench to
remove the bolt. (Fig. 3)
CAUTION
A diamond wheel for mounting on this
equipment must have 20 mm internal
diameter. No other sized diamond wheel
should be used.
CUTTING PROCEDURES
1. Set the machine body (base) on the
material to be cut; use the side on the base
to align the diamond wheel with the cutting
line. (Fig. 4)
2. Turn the switch ON with the diamond wheel
initially kept offthe material to be cut.
The power switch is turned ON when the
trigger is pulled by one’s finger, and is
turned OFF when the trigger is released. If
the stopper is depressed after the trigger is
pulled, the power switch becomes locked,
even though the trigger is released, proving
particularly convenient for continuous operation. When the power switch is to be turned
OFF, the stopper can be released by pulling the trigger, and the power switch is turned OFF
upon releasing the trigger.
CAUTION
○ Do not use the diamond wheel for cutting along curves or at angles; otherwise, it
may be damaged, resulting in extremely shortened service life.
○ Before starting to cut, confirm that the diamond wheel has attained full-speed
revolution.

MAINTENANCE AND INSPECTION
1. Inspecting the diamond wheel
Since use of a dull diamond wheel will cause motor malfunctioning and degraded
efficiently, replace with a new one without delay when abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened. Should
any of the screws be loose, retighten them immediately. Failure to do so could result in
serious hazard.
3. Maintenance of the motor
The motor unit winding is the very “heart” of the power tool. Exercise due care to ensure the
winding does not become damaged and/or wet with oil or water.
4. Inspecting the carbon brushes (Fig. 5)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with a new one having the same carbon brush
No. shown in the figure when it becomes worn to or
near the “wear limit”. In addition, always keep carbon
brushes clean and ensure that they slide freely within
the brush holders.
5. Replacing carbon brushes
Loosen the set screw and remove the tail cover. Remove the brush caps and carbon
brushes. After replacing the carbon brushes, do not forget to tighten the brush caps
securely and to install the tail cover.
6. Replacing supply cord
If the replacement of the supply cord is necessary, this has to be done by HiKOKI
Authorized Service Center in order to avoid a safety hazard.
If the supply cord of this power tool is damaged, it must be replaced by a specially prepared
cord available through the service organization.
