4.1 Safety Warnings Common for Grinding, Sanding, Wire Brushing or Cutting-Off Operations:

This power tool is intended for specific operations. Do not use for polishing or any unintended purpose. Use only Metabo-specified accessories. Ensure accessory speed rating is adequate. Accessory diameter and thickness must match tool capacity. Mounting dimensions must fit. Do not use damaged accessories. Inspect accessories before each use. Wear appropriate PPE. Keep bystanders away.

4.2 Kickback and related warnings:

Kickback is a sudden reaction to a pinched or snagged rotating accessory. Maintain a firm grip with both hands and position your body to resist kickback forces. Use the auxiliary handle. Never place your hand near the rotating accessory. Do not position your body in the area where the tool might move if kickback occurs. Use special care with corners, sharp edges, and avoid bouncing. Do not use saw chain woodcarving blades or segmented diamond wheels with gaps greater than 10 mm.

4.3 Safety warnings specific for grinding and cutting-off operations:

Use only specified wheel types and guards. Mount depressed wheels below the guard lip. Ensure the guard is securely attached and positioned for maximum safety. Use wheels only for specified applications; do not grind with the side of cut-off wheels. Use undamaged wheel flanges. Do not use worn wheels from larger tools. Use the correct guard for dual-purpose wheels.

4.4 Additional safety warnings specific for cutting-off operations:

Do not “jam” the cut-off wheel or apply excessive pressure. Do not attempt excessively deep cuts. Do not position your body in line with and behind the rotating wheel. When the wheel binds or a cut is interrupted, switch off the tool and wait for it to stop. Never attempt to remove a wheel while it is in motion. Restart cutting operations carefully. Support large workpieces to minimize pinching and kickback. Use extra caution for pocket cuts. Do not attempt curved cutting.

4.5 Safety warnings specific for sanding operations:

Use proper sized sanding disc paper. Ensure it does not extend too far beyond the sanding pad.

4.6 Safety warnings specific for wire brushing operations:

Be aware that wire bristles can be thrown. Do not overstress the brush. Ensure wire wheels or brushes do not interfere with the guard.

4.7 Additional Safety Instructions

Always wear protective goggles and ear protectors. Always operate the power tool with two hands. Do not use the guard for cutting-off operations; use the parting safety guard. Use only specific types of guards for dual-purpose wheels. Protect wheels from grease or impact. Store and handle accessories with care. Never use cut-off wheels for roughing or deburring. Secure small workpieces. Ensure ventilation openings are not blocked in dusty conditions.

4.8 Safety instructions for battery packs:

Protect battery packs from water and moisture. Do not expose to naked flame. Do not use faulty or deformed packs. Do not open packs. Avoid touching or short-circuiting packs. If battery fluid leaks, rinse skin immediately with water and seek medical attention if necessary. Remove battery pack if the machine is defective. Follow laws for shipping Li-ion battery packs.

6.3 Battery pack

Charge the battery pack before use. Recharge if performance diminishes. Refer to the Metabo charger's operating instructions for charging details. Battery packs have a capacity and signal display; press the button to view the charge level. A flashing LED indicates the battery pack is almost flat.

6.4 Removing and inserting the battery pack

Hold the machine to prevent accidental switching on. Press the battery pack release button to remove. Slide the battery pack in until it engages to insert.

7. Attaching the grinding wheel

Before any modifications, remove the battery pack and ensure the machine is switched off and the spindle is at a standstill. Attach the safety guard for cut-off grinding operations if necessary.

7.1 Locking the spindle

Press the spindle locking button and turn the spindle by hand until it engages.

7.2 Placing the wheel in position

Fit the support flange on the spindle. Ensure it does not turn. Place the grinding wheel flat on the support flange. The metal flange on cut-off wheels must also lay flat. Note: The support flange is secured; use some force if necessary for removal.

7.3 Securing/releasing the (tool-free) clamping nut

Only tighten the tool-free clamping nut manually. The clip must always lie flat on the clamping nut. Do not use the tool-free clamping nut if the accessory has a clamping shank thicker than 6 mm; use the clamping nut with a 2-hole spanner instead. Lock the spindle, flip up the clip, fit the clamping nut, and tighten manually clockwise. Flip down the clip. To release, lock the spindle, flip up the clip, and unscrew anticlockwise.

7.4 Securing/releasing the clamping nut (depending on features)

For thin grinding wheels, the edge of the clamping nut faces upwards. For thick grinding wheels, the edge faces downwards. Lock the spindle and turn the clamping nut clockwise using the 2-hole spanner to secure. To release, lock the spindle and turn anticlockwise.
