Intended Use

This tool is intended for cutting ferrous materials with an appropriate cut-off wheel. Observe the laws and regulations in your country concerning dust and workplace health and safety.

Power Supply

Connect the tool exclusively to a single-phase AC power source with a voltage matching that shown on the nameplate. The tool is double insulated, so it can be operated from an outlet without an earth conductor.

For use in public low-voltage distribution systems with voltages between 220 V and 250 V.

Voltage fluctuations may occur when switching on electrical equipment. Operating this device under unfavorable power supply conditions may adversely affect the operation of other equipment. If the mains impedance is 0.26 Ohm or less, negative phenomena are unlikely. The mains connection used for this device must be protected by a fuse or a circuit breaker with a slow-release characteristic.

Noise

Typical A-weighted sound pressure level, as determined by EN61029:

• Sound pressure level (LpA): 99 dB(A)
• Sound power level (LWA): 109 dB(A)
• Uncertainty (K): 3 dB(A)

Wear hearing protection.

Vibration

Vibration total value (triaxial vector sum) determined by EN61029:

• Vibration emission (ah): 4.0 m/s²
• Uncertainty (K): 1.5 m/s²

The vibration emission value has been measured according to the standard test procedure and can be used to compare electric power tools. The vibration emission value can be used for preliminary estimation of exposure. CAUTION: The vibration emission of the tool during actual use may differ from the stated value depending on the way it is used. Determine the operator protection measures based on the estimated exposure to vibration under actual operating conditions (considering elements of the work cycle, such as the frequency of machine shutdown and idling, as well as the number of starts).

Installation

Securing the Cut-off Saw

This tool must be secured to a horizontal and stable surface using the holes in the tool's base plate with two screws. This will prevent it from tipping over and causing personal injury.

Operating Instructions

CAUTION: Always ensure the tool is switched off and disconnected from the power supply before checking or adjusting it.

Using the Switch

CAUTION: Before connecting the tool to the power supply, always check that the switch trigger moves freely and returns to the OFF position when released.

Tool with Lock-off Button

To switch on the tool, simply pull the trigger. Release the trigger to stop. For continuous operation, pull the trigger and then press the lock-off button. To switch off the tool from the locked position, pull the trigger completely and then release it.

Tool with Release Button

A release button prevents the trigger from being accidentally pulled. To switch on the tool, press the release button and pull the trigger. Release the trigger to stop.

Spark Guard Adjustment

The spark guard is factory-fitted so its lower edge touches the base plate. Operating the tool in this position may cause sparks to scatter widely. Loosen the screw and adjust the spark guard to a position where the amount of scattering sparks is minimized.

Gap Between Clamp and Guide Plate

The original distance or gap between the clamp and the guide plate is 0 - 170 mm. If you need a larger distance or gap for your work, proceed as follows: Remove the two hex socket screws that secure the guide plate. Move the guide plate as shown in the diagram, then secure it with the hex socket screws. The following distance adjustments are possible: 35 - 205 mm, 70 - 240 mm.

CAUTION: Remember that narrow workpieces cannot be securely clamped if you use the wider distance settings.

Assembly

CAUTION: Always ensure the tool is switched off and disconnected from the power supply before performing any work on it.

Mounting and Removing the Cut-off Blade

To remove the blade, lift the safety guard. Press the spindle lock completely to prevent the blade from rotating, and loosen the hex socket screw with the socket wrench in a counter-clockwise direction. Then remove the hex socket screw, outer flange, and blade. (Note: Do not remove the inner flange, ring, and O-ring.) When installing the blade, follow the removal procedure in reverse order.

CAUTION: Ensure the hex socket screw is tightened firmly. Insufficient tightening of the hex socket screw can cause serious injury. Use the supplied socket wrench to ensure proper tightening.

Always use the appropriate inner and outer flanges supplied with the tool. Always lower the safety guard after changing the blade.

Securing the Workpiece

By turning the clamp handle counter-clockwise and tilting the clamp bolt to the left, the clamp is released from the thread and can be moved outwards and inwards quickly. To clamp workpieces, push the clamp lever until the clamp plate contacts the workpiece. Tilt the clamp bolt to the right, then turn the clamp handle clockwise to secure the workpiece.

CAUTION: Always move the clamp bolt fully to the right when clamping the workpiece. Failure to do so will result in improper clamping. This can cause the workpiece to be ejected or the blade to break dangerously.

When the cut-off blade is significantly worn, use a spacer block made of a solid, non-flammable material behind the workpiece as shown in the diagram. The worn blade can be used more effectively by cutting with the center of the blade's edge.

When cutting workpieces larger than 65 mm at an angle, attach a straight piece of wood (spacer) that is 190 mm long x 45 mm wide, or larger, to the guide plate as shown in the diagram. Screw the spacer to the guide plate using the holes provided.

If using a spacer block that is slightly narrower than the workpiece, as shown in the diagram, the blade can be used economically.

Long workpieces should be supported with blocks made of non-flammable material on both sides, so that they are level with the top surface of the machine's base plate.

Operation

Hold the tool firmly. Switch on the tool and wait for the blade to reach full speed before lowering it for the cut. When the blade contacts the workpiece, gradually apply pressure to the handle to complete the cut. After finishing the cut, switch off the tool and WAIT FOR THE BLADE TO STOP COMPLETELY before returning the handle to the fully raised position.

CAUTION: The correct handle pressure and maximum cutting efficiency can be determined by the amount of sparks produced during the cut. The pressure applied to the handle should be adjusted to produce the maximum amount of sparks. Do not force the cut by applying excessive pressure to the handle. Reduced cutting efficiency, premature blade wear, and damage to the tool, cut-off blade, or workpiece may result.

Cutting Performance

Maximum cutting performance depends on the cutting angle and the shape of the workpiece. Applicable blade diameter: 355 mm.

Maintenance

CAUTION: Always ensure the tool is switched off and disconnected from the power supply before performing any inspection or maintenance.

Never use gasoline, benzine, thinner, alcohol, or similar substances. These can cause discoloration, deformation, or cracking.

Replacing Carbon Brushes

Replace and inspect the carbon brushes regularly. Replace them when they are worn down to the limit mark. Keep the carbon brushes clean and ensure they can move freely in their holders. Replace both carbon brushes at the same time. Use identical carbon brushes.

Remove the brush holder caps using a screwdriver. Remove the worn carbon brushes, insert the new ones, and replace the brush holder caps.

For the safety and reliability of the product, repairs, any other maintenance, or adjustment should be performed by Makita Authorized Service Centers, always using Makita replacement parts.
