Usage Features
The manual outlines various usage features and safety precautions for different operations:
General Operation:
- Firm Grip: Always hold the tool firmly with both hands, one on the housing and the other on the auxiliary handle.
- Dust Collection: For clean concrete-planing, connect a Makita vacuum cleaner to the tool. The dust collecting wheel guard is specifically designed for this purpose.
- Corner Planing: The front-edge cover can be removed by sliding it to allow planing in corners.
Accessory Installation:
- Loop Handle: Installs securely with bolts and a hex wrench, only in a specified direction.
- Dust Collecting Wheel Guard: Must be installed before operation as a concrete planer. It aligns with a protrusion on the bearing box and is secured with a screw.
- Offset Diamond Wheel: Mounts onto the spindle with an inner flange and a lock nut. For thinner wheels (4 mm or less), the convex section of the lock nut faces upwards. Requires a genuine Makita offset diamond wheel.
- Side Grip (Handle): Screws securely onto the tool.
- Wheel Guard (for depressed center wheel, flap disc, flex wheel, wire wheel brush / abrasive cut-off wheel, diamond wheel):
- For depressed center wheels, flap discs, flex wheels, and wire wheel brushes, the closed side of the guard must point towards the operator.
- For abrasive cut-off/diamond wheels, a special wheel guard designed for cut-off wheels must be used (though in some European countries, an ordinary guard may be used for diamond wheels, depending on local regulations).
- Mounts with protrusions aligning with notches on the bearing box, then rotates to protect the operator. Some models feature a clamp lever for adjustment.
- Depressed Center Wheel or Flap Disc: Mounts with an inner flange and a lock nut. The inner flange's dented part must fit the straight part at the bottom of the spindle.
- Ezynut (Optional, M14 spindle thread only): Mounts with an inner flange, abrasive wheel, and Ezynut (Makita logo facing outside). Tightened by turning the abrasive wheel clockwise. Loosened by turning the outside ring counterclockwise, possibly with a lock nut wrench.
- Flex Wheel: Requires the supplied guard. Mounts with a back-up pad over the wheel, following instructions for depressed center wheels.
- Abrasive Disc: Mounts with a rubber pad and a sanding lock nut.
- Wire Cup Brush: Threads directly onto the spindle.
- Abrasive Cut-off / Diamond Wheel: Requires a special wheel guard. The direction for mounting the lock nut and inner flange varies by wheel type and thickness.
Operation Specifics:
- Grinding and Sanding: Do not force the tool; its weight provides adequate pressure. Avoid banging the disc/wheel, bouncing, or snagging, especially in corners. Never use wood cutting or saw blades.
- Wire Cup Brush: Check operation with no load. Avoid excessive pressure to prevent premature wire breakage.
- Abrasive Cut-off / Diamond Wheel: Do not "jam" the wheel or apply excessive pressure. Do not start cutting in the workpiece; let the wheel reach full speed first. Maintain a consistent angle (perpendicular for diamond wheels).
Maintenance Features
Regular maintenance is crucial for the tool's safety and reliability.
- Cleaning Air Vents: The tool's air vents must be kept clean to prevent obstruction.
- Replacing Dust Cover Brush: Worn brushes can be pulled off and new ones inserted into retaining grooves, ensuring they are fully hooked onto the outer edges of the grooves.
- General Maintenance: All repairs, carbon brush inspection and replacement, and other maintenance should be performed by Makita Authorized or Factory Service Centers using genuine Makita replacement parts.
- Cleaning Agents: Never use gasoline, benzine, thinner, alcohol, or similar substances, as they can cause discoloration, deformation, or cracks.
Safety Reminders:
- Always switch off and unplug the tool before any adjustments, accessory changes, or maintenance.
- Wear appropriate personal protective equipment, including safety goggles, ear protection, and a dust mask.
- Ensure the work area is clean, well-lit, and free of flammable materials.
- Keep children and bystanders away from the operating area.
