BOSCH GCM 18V-216 PROFESSIONAL (01) PDF DOCUMENT

Note: Speed measured at 20−25 °C with rechargeable battery ProCORE18V 8.0Ah. Weight depends on the battery in use. Limited performance at temperatures <0 °C.

Noise emission values are determined according to EN 62841-3-9.

Typically, the A-weighted noise level of the power tool is:

Sound pressure level 95 dB(A); sound power level 104 dB(A). Uncertainty K = 3 dB.

Wear hearing protection!

The noise emission value given in these instructions has been measured in accordance with a standardised measuring procedure and may be used to compare power tools. It may also be used for a preliminary estimation of noise emissions.

The noise emission value given represents the main applications of the power tool. However, if the power tool is used for other applications, with different application tools or is poorly maintained, the noise emission value may differ. This may significantly increase noise emissions over the total working period.

To estimate noise emissions accurately, the times when the tool is switched off, or when it is running but not actually being used, should also be taken into account. This may significantly reduce noise emissions over the total working period.

Check to ensure that all the parts listed below have been supplied before using the power tool for the first time:

Sliding mitre saw with mounted saw blade

Dust bag (2)

Transport handle (4), two screws for assembly

SDS bolt (46)

Screw clamp (26)

Hex key (41)

Use only the chargers listed in the technical data. Only these chargers are matched to the lithium-ion battery of your power tool.

Note: The battery is supplied partially charged. To ensure full battery capacity, fully charge the battery in the charger before using your power tool for the first time.

The lithium-ion battery can be charged at any time without reducing its service life. Interrupting the charging process does not damage the battery.

The lithium-ion battery is protected against deep discharge by the “Electronic Cell Protection (ECP)”. When the battery is discharged, the power tool is switched off by means of a protective circuit: The application tool no longer rotates.

Do not continue to press the On/Off switch after the power tool has automatically switched off. The battery can be damaged.

Removing the Battery

The battery (34) is equipped with two locking levels to prevent the battery from falling out if the battery release button (35) is pressed unintentionally. The battery is held in place by a spring when fitted in the power tool.

To remove the battery, press the release button and pull the battery out of the power tool. Do not use force to do this.

Battery charge indicator

The green LEDs on the battery charge indicator indicate the state of charge of the battery. For safety reasons, it is only possible to check the state of charge when the power tool is not in operation.

Press the button for the battery charge indicator to show the state of charge. This is also possible when the battery is removed.

If no LED lights up after pressing the button for the battery charge indicator, then the battery is defective and must be replaced.

Fitting the transport handle

Screw the transport handle (4) into the corresponding threads with the screws supplied.

Stationary or flexible mounting

To ensure safe handling, the power tool must be mounted on a flat, stable work surface (e.g. work bench) before use.

Mounting on a work surface

Use suitable screw fasteners to secure the power tool to the work surface. Use the holes (16) to do this.

Mounting on a Bosch saw stand

With the height-adjustable legs, Bosch GTA saw stands provide firm support for the power tool on any surface. The workpiece supports of the saw stand are used for underlaying long workpieces.

Flexible installation (not recommended)

If, in exceptional circumstances, it is not possible to mount the power tool on a flat and stable work surface, you can improvise by setting it up with the tilt protector (21).

Without the tilt protector, the power tool will not be stable and can tip over especially when sawing maximum mitre and/or bevel angles.

Rotate the tilt protector (21) inwards or outwards until the power tool is positioned straight on the work surface.

Self-generated dust extraction

For basic chip collection, use the dust bag (2) provided.

1. Attach the dust bag (2) to the chip ejector (3).

2. During sawing, the dust bag must not come into contact with moving tool components.

3. Always empty the dust bag in good time.

4. Check and clean the dust bag each time after using.

5. When sawing aluminium, remove the dust bag to avoid the risk of fire.

External Dust Extraction

You can also attach a dust extraction hose (35 mm diameter) to the chip ejector (3) for extraction.

1. Connect the dust extraction hose to the chip ejector (3).

2. The dust extractor must be suitable for the material being worked.

3. When extracting dry dust that is especially detrimental to health or carcinogenic, use a special dust extractor.
