GENERAL SAFETY RULES
(For All Tools)
WARNING! Read and understand all instructions. Failure to follow all
instructions listed below, may result in electric shock, fire and/or serious
personal injury.
SAVE THESE INSTRUCTIONS
READ ALL INSTRUCTIONS.
-
Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
-
Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
-
Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to loose control. -
Double Insulated tools are equipped with 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 a polarized outlet. Do not change the plug in any way. Double insulation H eliminates the need for the three wire grounded power cord and grounded power supply system.
-
Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.
-
Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
-
Do not abuse the cord. Never use the cord t o carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.
-
When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W.” These cords are rated for outdoor use and reduce the risk of electric shock.
-
Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
-
Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
-
Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch on invites accidents.
-
Remove adjusting keys or switches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.
-
Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.
-
Use safety equipment. Always wear eye protection. Dust mask, nonskid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.
-
Use clamps or other practical way t o secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.
-
Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.
-
Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
-
Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.
-
Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
-
Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with sharp cutting edges are less likely to bind and are easier to control.
-
Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tools operation. If damaged, have the tool service before using. Many accidents are caused by poorly maintained tools.
-
Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool.
-
Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.
-
When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of electric shock of injury.
Specific Safety Rules
-
Always use proper guard with grinding wheel. A guard protects operator from broken wheel fragments.
-
Accessories must be rated for at last the speed recommended on the tool
warning label. Wheels and other accessories running over rated speed can fly apart and cause injury. -
Hold tool by insulated gripping surfaces when performing an operation where
the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator. -
Keep guards in place.
-
Use only wheels having a maximum operating speed at least as high as “No Load RPM” marked on the tool’s nameplate. When using depressed center wheels, be sure t o use only fiberglass-reinforced wheels.
-
Check the wheel carefully for cracks or damage before operation. Replace cracked or damaged wheel immediately.
-
Use only flanges specified for this tool.
-
Be careful not t o damage the spindle, the flange (especially the installing surface) or the lock nut. Damage t o these parts could result in wheel breakage.
-
Hold the tool firmly.
-
Keep hands away from rotating parts.
-
Make sure the wheel is not contacting the workpiece before the switch is turned on.
-
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.
-
Use the specified surface of the wheel to perform the grinding.
-
Watch out for flying sparks. Hold the tool so that sparks fly away from you and other persons or flammable materials.
-
Do not leave the tool running. Operate the tool only when hand-held. 16.Do not touch the workpiece immediately after operation; it may be extremely hot and could burn your skin.
SAVE THESE INSTRUCTIONS.
SYMBOLS
The followings show the symbols used for tool.
Installing wheel guard
When using a depressed center wheel or an abrasive cut-off wheel, always use a
wheel guard. Mount the wheel guard with the tab on the wheel guard band
aligned with the notch on the bearing box Then rotate the wheel guard 160
degrees counterclockwise.
Installing side grip (auxiliary handle)
Always install the side grip on the tool securely before operation. The side
grip can be installed in any of three positions on the sides of the tool,
whichever is convenient and keeps the guard properly positioned. Always hold
the tool’s switch handle and the side grip firmly with both hands during
operation.
WARNING:
Side grip only in such a way that grinding wheel will not contact any part of
your body and that wheel guard always remains positioned as a barrier between
the grinding wheel and the operator. Failure t o do so may result in serious
injury.
Installing or removing depressed center wheel
CAUTION: Always be sure that the tool is switched off and unplugged before
installing or removing the wheel.
Mount the inner flange onto the spindle. Fit the wheel on over the inner
flange and screw the lock nut onto the spindle.
To tighten the lock nut, press the shaft lock firmly so that the spindle
cannot revolve, then use the lock nut wrench and securely tighten clockwise.
To remove the wheel, follow the installation procedure in reverse
Switch action
To start the tool, simply pull the trigger.
Release the trigger to stop. For continuous operation, pull the trigger and
then push in the lock lever. To stop the tool from the locked position, pull
the trigger fully, then release it.
CAUTIO N: Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.
Operation
Hold the tool firmly. Turn the tool on and then apply the wheel or disc to the
workpiece. In general, keep the edge of the wheel or disc at an angle of about
15O to the workpiece surface.
During the break-in period with a new wheel, do not work the grinder in the B
direction or it will cut into the workpiece. Once the edge of the wheel has
been rounded off by use, the wheel may be worked in both A and B directions.
WARNING:
- It should never be necessary to force the tool. The weight of the tool applies adequate pressure. Forcing and excessive pressure could cause dangerous wheel breakage.
- Continued use of a worn-out wheel may result in wheel explosion and serious personal injury. Depressed center wheel should not be used after it has been worn down to 115 mm (4-1/2″) in diameter. Use of the wheel after this point is unsafe and it should be removed from service and rendered unusable by intentional destruction.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and unplugged before attempting t
o perform inspection or maintenance.
Replacing carbon brushes
When the resin insulating tip inside the carbon brush is exposed t o contact
the commutator, it will automatically shut off the motor. When this occurs,
both carbon brushes should be replaced at the same time. Use only identical
carbon brushes.
Use a screwdriver to remove the brush holder caps. Take out the worn carbon brushes, insert the new ones and secure the brush holder caps.
To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts.
ACCESSORIES
CAUTION: These accessories or attachments are recommended for use w i t h your Makita tool specified in this manual. The use of any other accessories or attachments might present a risk of injury to persons. The accessories or attachments should be used only in the proper and intended manner.
