Safety warnings for angle grinders

Select the right disc

CAUTION • Never use discs with bigger diameter than the size required in the tool.
WARNING • Use only discs or accessories for minimum or more than 11000 RPM speeds.
CAUTION • Use only discs or accessories with an orifice that fits perfectly in the tool spindle.
CAUTION • Use only discs or accessories specifically designed for the chosen material.

Before operating the grinder

• Set apart some time and assess the job you are about to do. Pay attention to all the necessary cautions before starting to grind.
  DANGER • Remove all the fastening wrenches from the tool. Otherwise they can shoot away causing sever injuries to the user.
  WARNING • Double-check the guard. It should be perfectly fastened and in good working condition. Do not use the tool without a guard.
  CAUTION • Double-check the disc. It should not be broken or cracked. Tap the disc gently with a wooden hammer and listen for a strange sound to learn if is cracked.
  DANGER • Before plugging the tool, see if is in the OFF position. Otherwise the tool could start unexpectedly causing severe injuries.
  CAUTION • Run the tool 30 seconds before using, to detect important vibration or any type of unusual movement. If detected, unplug the tool and take it to a TRUPER Authorized Service Center.
  CAUTION • See if the disc rotates freely. • Do not tighten the disc. It could brake.
  WARNING • To work with small work pieces fasten with wrenches. Never use your hands to hold the piece.

While operating the grinder

CAUTION • Do not start the tool when the disc is touching the work piece.

WARNING • Wear safety glasses, gloves and an apron when using the tool.

WARNING • Keep the power cable or extension in the back of the tool. Avoid accidentally damaging the cables with the disc.

WARNING • Never hold the tool by the power cable. Hold by the housing or auxiliary handle.

CAUTION • Hold the tool by the isolated parts.

The cutting tool could come into contact with hidden wiring or its own cable. Making contact with a "live" wire causes the metal parts to electrify and give an electric shock to the user.

- Never hit the work surface with the disc.

CAUTION • To get the best result with the grinding process, the inclination of the disc and the working surface should have an angle measuring 15^ to 30^

DANGER • When the disc is rotating never use the spindle lock to stop it. It is very dangerous and may cause injuries to the user.

CAUTION • Do not touch the disc or the working piece after grinding. Wait for them to cool down. Never try to cool them down using water or oil.

WARNING • Before checking, adjusting or changing discs, double-check the tool is not plugged in.

DANGER • Sparks caused when grinding may be dangerous. Use caution. Make sure sparks do not get into contact with skin or flammable substances.

Auxiliary Handle Assembly

- For a safer operation use the auxiliary handle. Fit it into any of the two mounting orifices. Use the one that make your job easier.

Start Up

The angle grinder is a manual power tool. It is used to grind and cut steel, pipes, and angles in iron, bricks, tiles, stone and/or ceramic pieces. Also to remove burr from metal surfaces, to level and smoothing out soldering. When changing the tool accessory, it can be used to clean rust and to buff metal surfaces and other materials.

Switch On

- Intermittent operation: Connect the plug into the power outlet. Press switch (A) to start the tool. To stop, just release the switch.

- Continuous operation: Connect the plug into the power outlet. Press switch (A) and block it pressing the continuous use button (B). To stop, press and then release the switch

How to correctly hold the tool

Always hold the tool using both hands. One hand holds the handle and the other hand on the auxiliary handle. Use care not to obstruct the ventilation slots.

- Grinding: For better results hold the tool at an angle of 15^ to 30^ with regards to the work piece. Move backward and forward with a constant rhythm and a slight pressure. This way the work piece will not get too hot, will not fade and rough edges will not appear. - Cutting: Do not press, tilt or oscillate the tool. Use a moderate speed. The disc should always rotate in a movement opposite to the cutting movement. Never the other way around, as there is danger that the tool shoots out of control. For cutting hard stone, using a diamond disc is recommended.

Useful Tips

• To prevent damaging the disc work using the disc into the right position.
- Press onto the work piece using less force than the tool's weight to avoid overload and damaging the motor and disc.
- After installing a new disc allow it to rotate with no load at least during one minute. If it vibrates, replace immediately.

CAUTION • Avoid working onto wood or soft materials like lead. These materials saturate the disc very fast and make it unusable.

Maintenance

• Before cleaning the tool disconnect the tool.
- Never use water or other liquids. Use only a brush.
• To avoid motor overheating clean the ventilation slots regularly.
- Double-check all the tool components are securely fastened.
• The housing should not be cracked or damaged.
- Double-check the power cable is not cut or peeled.
• After a prolonged use the grease on the tool head should be replaced in a
TRUPER Authorized Service Center.

Repairs

Use only spare parts and accessories recommended by the manufacturer. In the event the tool is not working, repairs should be carried out in a

TRUPER Authorized Service Center.

Carbon Brush Replacement

• Replace worn (burnt, broken or smaller than 0.19" long) carbon brushes. Use new carbons.
• When replacing carbons always replace both carbons at the same time.
• Remove worn carbons from the housing. Clean accumulated dust with compressed air.
• Set the new carbons in a reverse order. Carbons should easily fall into the carbon housing.
  • After setting up new carbon brushes let the grinder running a couple of minutes unloaded. This way the carbon brushes will adjust better.
• Use only original TRUPER spare carbon brushes, designed specifically with the right strength and electric resistance for each type of motor. Carbon brushes with different specifications may damage the motor.

Storage

Store the tool neatly in a dry place. Protect against dust and water.
