IMPORTANT SAFETY INSTRUCTIONS
FOR USE OF THE CUT-OFF MACHINE
WARNING: Death or serious bodily injury could result from improper or unsafe use
of the cut-off machine. To avoid these risks, follow these basic safety
instructions:
1. Never operate these power tools without wheel guards
2. Use only cutting wheels with a "Safe Speed" at least as high as the "No-Load RPM"
indicated on the power tool nameplate.
REPLACEMENT PARTS
When servicing use only identical replacement parts.
Repairs should be conducted only by a Hitachi authorized service center.
POLARIZED PLUGS
To reduce the risk of electrick shock, this equipment has a polarized plug (one blade is wider
than the other).
This plug will fit in a polarized outlet only one way.
If the plug does not fit fully in the outlet, reverse the plug.
If it still does not fit, contact a qualified electrician to install the proper outlet.
Do not change the plug in any way.
7
English
USE OF EXTENSION CORD
Make sure your extension cord is in good condition. When using an extension cord, be sure
to use one heavy enough to carry the current your product will draw.
An undersized cord will cause a drop in line voltage resulting in loss of power and
overheating. Table shows the correct size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the
heavier the cord.

WARNING: Avoid electrical shock hazard. Never use this tool with a damaged or
frayed electrical cord or extension cord.
Inspect all electrical cords regularly. Never use in or near water or in any
environment where electric shock is possible.

English
DOUBLE INSULATION FOR SAFER OPERATION
To ensure safer operation of this power tool, HITACHI has adopted a double insulation
design. “Double insulation “ means that two physically separated insulation systems have
been used to insulate the electrically conductive materials connected to the power supply
from the outer frame handled by the operator. Therefore, either the symbol “
and “Double insulation” appear on the power tool or on the nameplate.
Although this system has no external grounding, you must still follow the normal electrical
safety precautions given in this Instruction Manual, including not using the power tool in wet
environments.
To keep the double insulation system effective, follow these precautions:
䡬 Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assemble this
power tool, and only genuine HITACHI replacement parts should be installed.
䡬 Clean the exterior of the power tool only with a soft cloth moistened with soapy water,
and dry thoroughly.
Never use solvents, gasoline or thinners on plastic components; otherwise the plastic
may dissolve.

PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms to the power source requirements
specified on the product nameplate.
2. Power switch
Ensure that the switch is in the OFF position. If the plug is connected to a receptacle while
the switch is in the ON position, the power tool will start operating immediately and can
cause serious injury.
3. Extension cord
When the work area is far away from the power source, use an extension cord of sufficient
thickness and rated capacity. The extension cord should be kept as short as practicable.
WARNING: Damaged cord must be replaced or repaired.
4. Check the receptacle
If the receptacle only loosely accepts the plug, the receptacle must be repaired. Contact
a licensed electrician to make appropriate repairs.
If such a fautly receptacle is used, it may cause overheating, resulting in a serious hazard.
11
English
5. Confirming condition of the environment:
Confirm that the work site is placed under appropriate conditions conforming to
prescribed precautions.
6. Fitting and adjusting the wheel guard
The wheel guard is a protective device to prevent injury should the cutting wheel shatter
during operation. Ensure that the guard is properly fitted and fastened before commencing
cutting operation. By slightly loosening the setting screw, the wheel guard can be turned
and set at any desired angle for maximum operational effectiveness. Ensure that the
setting screw is thoroughly tightened after adjusting the wheel guard.
7. Cutting wheel
Ensure that the cutting wheel to be utilized is
the correct type and free of cracks or surface
defects. Also ensure that the cutting wheel is
properly mounted and the wheel nut is securely
tightened. Refer to the section on “Cutting Wheel
Assembly”.
Wheel nut
Inner washer
8. Conducting a trial run
Before commencing cutting operation, the
machine should be given a trial run in a safe
area to ensure that it is properly assembled and
that the cutting wheel is free from obvious
defects.
Recommended trial runs durations are as
follows:
After replacing
cutting wheel ......... 3 minutes or more
Prior to starting
routine work ...........1 minute or more
9. Confirming the lock pin.
Confirm that the lock pin is disengaged by
pushing lock pin two or three times before
switching the power tool on (See Fig. 2).

PRACTICAL CUT-OFF MACHINE APPLICATION
1. Cutting force
To prolong the life of the machine and ensure a first class finish. It is important that the
machine should not be overloaded by applying too much force.
2. Precautions immediately after finishing operation
After switching off the machine, do not put it down until the cutting wheel has come to
a complete stop. Apart from avoiding serious accidents, this precaution will reduce the
amount of dust and swarf sucked into the machine.
CAUTION:
After operation, always place the machine so that the cutting wheel faces upward.
When the machine is not in use, the power source should be disconnected.
12
CUTTING WHEEL ASSEMBLY
English
1. Assembling (Fig. 2, 3)
(1) Turn the machine upside down so that the
spindle is facing upward.
(2) Mount the wheel washer onto the spindle.
(3) Fit the protuberance of the cutting wheel onto
the wheel washer.
(4) Put the inner washer on the cutting wheel, and
screw the wheel nut onto the spindle.
(5) Insert the lock pin to prevent rotation of the
spindle, and tighten the wheel nut with accessory
wrench, as shown in Fig. 3.
CAUTION:
After attaching the cutting wheel, check that the cutting wheel does not come into
contact with wheel guard and base.
Wrench
Lock pin

2. Disassembling
Follow the above procedures in reverse.
MAINTENANCE AND INSPECTION
WARNING: Be sure to switch power OFF and disconnect the plug from the receptacle
during maintenance and inspection.
1. Inspecting the cutting wheel
Ensure that the cutting wheel is free of cracks and surface defects.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened.
Should any of the screws be lossened, retighten them immediately.
WARNING: Using this cut-off machine with loosened screws is extremely dangerous.
13
English
3. Inspecting the carbon brushes (Fig. 4)
Wear limit
The Motor employs carbon brushes which are
consumable parts. When they become worn to
or near the ”wear limit“, it could result in motor
trouble. When an auto-stop carbon brush is
equipped, the motor will stop automatically. At
that time, replace both carbon brushes with

new ones which have the same carbon brush
Numbers shown in the figure. In addition,
always keep carbon brushes clean and ensure
that they slide freely within the brush holders.
NOTE: Use HITACHI carbon brush number

be easily removed.
SERVICE AND REPAIRS
All quality power tools will eventually require servicing or replacement of parts because of
wear from normal use. To assure that only authorized replacement parts will be used, all
service and repairs must be performed by a HITACHI AUTHORIZED SERVICE CENTER,
ONLY.
NOTE:
Specifications are subject to change without any obligation on the part of the HITACHI.
