DIE GRINDER SAFETY WARNINGS
Safety Warnings Common for Grinding Operation:
- This power tool is intended to function as a grinder. Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
- Operations such as sanding, wire brushing, polishing or cutting-off are not recommended to be performed with this power tool. Operations for which the power tool was not designed may create a hazard and cause personal injury.
- Do not use accessories which are not specifically designed and recommended by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation.
- The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories running faster than their rated speed can break and fly apart.
- The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately controlled.
- The arbour size of accessories must properly fit the collet of the power tool. Accessories that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
- Mandrel mounted accessories must be fully inserted into the collet or chuck. If the mandrel is insufficiently held and/or the overhang of the wheel is too long, the mounted accessory may become loose and be ejected at high velocity.
- Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks. If power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute. Damaged accessories will normally break apart during this test time.
- Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
- Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation.
- Hold power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
- Always hold the tool firmly in your hand(s) during the start-up. The reaction torque of the motor, as it accelerates to full speed, can cause the tool to twist.
- Use clamps to support workpiece whenever practical. Never hold a small workpiece in one hand and the tool in the other hand while in use. Clamping a small workpiece allows you to use your hand(s) to control the tool. Round material such as dowel rods, pipes or tubing have a tendency to roll while being cut, and may cause the bit to bind or jump toward you.
- Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory.
- Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the surface and pull the power tool out of your control.
- After changing the bits or making any adjustments, make sure the collet nut, chuck or any other adjustment devices are securely tightened. Loose adjustment devices can unexpectedly shift, causing loss of control, loose rotating components will be violently thrown.
- Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your clothing, pulling the accessory into your body.
- Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.
- Do not operate the power tool near flammable materials. Sparks could ignite these materials.
- Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged rotating accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation. For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on direction of the wheel’s movement at the point of pinching. Abrasive wheels may also break under these conditions.
Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.
a) Maintain a firm grip on the power tool and position your body and arm to
allow you to resist kickback forces. The operator can control kickback
forces, if proper precautions are taken.
b) Use special care when working corners, sharp edges etc. Avoid bouncing
and snagging the accessory. Corners, sharp edges or bouncing have a tendency
to snag the rotating accessory and cause loss of control or kickback.
c) Do not attach a toothed saw blade. Such blades create frequent kickback
and loss of control.
d) Always feed the bit into the material in the same direction as the
cutting edge is exiting from the material (which is the same direction as the
chips are thrown). Feeding the tool in the wrong direction causes the
cutting edge of the bit to climb out of the work and pull the tool in the
direction of this feed.
Safety Warnings Specific for Grinding:
a) Use only wheel types that are recommended for your power tool and
only for recommended applications.
b) Do not position your hand in line with and behind the rotating wheel.
When the wheel, at the point of operation, is moving away from your hand, the
possible kickback may propel the spinning wheel and the power tool directly at
you.
Additional Safety Warnings:
21. The tool is intended for use with bonded abrasive wheel points
(grinding stones) permanently mounted on plain, unthreaded mandrel
(shanks).
22. Make sure the wheel is not contacting the workpiece before the switch
is turned on.
23. Before using the tool on an actual workpiece, let it run for a
while. Watch for vibration or wobbling that could indicate poor
installation or a poorly balanced wheel.
24. Use the specified surface of the wheel to perform the grinding.
25. Watch out for flying sparks. Hold the tool so that sparks fly away
from you and other persons or flammable materials.
26. Do not leave the tool running. Operate the tool only when hand-
held.
27. Do not touch the workpiece immediately after operation; it may be
extremely hot and could burn your skin.
28. Observe the instructions of the manufacturer for correct mounting
and use of wheels. Handle and store wheels with care.
29. Check that the workpiece is properly supported.
30. If working place is extremely hot and humid, or badly polluted by
conductive dust, use a shortcircuit breaker (30 mA) to assure operator
safety.
31. Do not use the tool on any materials containing asbestos.
32. Always be sure you have a firm footing. Be sure no one is below
when using the tool in high locations.

Speed adjusting dial (Fig. 2)
The tool speed can be changed by turning the speed adjusting dial to a given
number setting from 1 to 5.
Higher speed is obtained when the dial is turned in the direction of number 5.
And lower speed is obtained when it is turned in the direction of number 1.
Refer to the table for the relationship between the number settings on the
dial and the approximate tool speed.
CAUTION:
- If the tool is operated continuously at low speeds for a long time, the motor will get overloaded, resulting in tool malfunction.
- The speed adjusting dial can be turned only as far as 5 and back to 1. Do not force it past 5 or 1, or the speed adjusting function may no longer work.
ASSEMBLY
CAUTION:
- Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.
Installing the side handle (Fig. 3)
Always use the side handle to ensure operating safety.
Install the side handle on the tool barrel, then tighten the handle by turning clockwise at the desired position.
Installing or removing wheel point (Fig. 4 & 5)
Loosen the collet nut and insert the wheel point into the collet nut. Use the
smaller wrench to hold the spindle and the larger one to tighten the collet
nut securely.
The wheel point should not be mounted more than 10 mm from the collet nut.
Exceeding this distance could cause vibration or a broken shaft.
To remove the wheel point, follow the installation procedure in reverse.
CAUTION:
- Use the correct size collet cone for the wheel point which you intend to use.
