Torque limiter

The torque limiter will actuate when a certain torque level is reached. The motor will disengage from the output shaft. When this happens, the bit will stop turning.

CAUTION:

As soon as the torque limiter actuates, switch off the tool immediately. This will help prevent premature wear of the tool.

Chipping/Scaling/Demolition (Fig. 16)

Set the change lever and the shift lever to the gsymbol. Hold the tool firmly with both hands. Turn the tool on and apply slight pressure on the tool so that the tool will not bounce around, uncontrolled. Pressing very hard on the tool will not increase the efficiency.

Drilling operation (Fig. 17)

Use the optional drill chuck assembly. When installing it, refer to “Installing or removing drill bit” described on the previous page. You can drill up to 13 mm diameter in metal and up to 30 mm diameter in wood.

Set the change lever and the shift lever to the symbol.

Drilling in wood

When drilling in wood, best results are obtained with wood drills equipped with a guide screw. The guide screw makes drilling easier by pulling the bit into the workpiece.

Drilling in metal

To prevent the bit from slipping when starting a hole, make an indentation with a centerpunch and hammer at the point to be drilled. Place the point of the bit in the indentation and start drilling.

Use a cutting lubricant when drilling metals. The excep- tion is brass which should be drilled dry.

CAUTION:

Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pressure will only serve to damage the tip of your bit, decrease the tool perfor- mance and shorten the service life of the tool.

Never use “rotation with hammering” when the drill chuck assembly is installed on the tool. The drill chuck assembly may be damaged.

Depth gauge (Fig. 18)

The depth gauge is convenient for drilling holes of uni- form depth. Loosen the clamp screw and adjust the depth gauge to the desired depth. After adjusting, tighten the clamp screw firmly.

NOTE:

The depth gauge cannot be used at the position where the depth gauge strikes against the gear housing/motor housing.

Indicator lamp (Fig. 19)

The green power-ON indicator lamp lights up when the tool is switched ON. If the indicator lamp is lit but the tool does not start, the carbon brushes may be worn out, or the electric circuit or the motor may be defective. If the indicator lamp does not light up and the tool does not start, the ON/OFF switch or the mains cord may be defective.

The red service indicator lamp lights up when the carbon brushes are nearly worn out to indicate that the tool needs servicing. After approx. 8 hours of use, the motor will automatically be shut off.

MAINTENANCE

CAUTION:

Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.

Replacement of carbon brushes (Fig. 20 & 21)

Whenever carbon brushes must be replaced, they cut out the tool automatically. When this occurs, remove the screws which secure the brush holder cover. Remove the brush holder cover and brush holder cap. Then replace both carbon brushes at the same time. Use only identical carbon brushes.

Lubrication

This tool requires no hourly or daily lubrication because it has a grease-packed lubrication system. Lubricate the tool every time the carbon brushes are replaced.

Run the tool for several minutes to warm it up. Switch off and unplug the tool.

Loosen the six screws and remove the handle. Note that the top screws are different from other screws. (Fig. 22) Disconnect the connector by pulling it. (Fig. 23)

Remove the crank cap using a hex wrench. (Fig. 24) Rest the tool on the table with the bit end pointing upwards. This will allow the old grease to collect inside the crank housing. Wipe out the old grease inside and replace with a fresh grease (30 g). Use only Makita genu- ine hammer grease (optional accessory). Filling with more than specified amount of grease (approx. 30 g) can cause faulty hammering action or tool failure. Fill only with the specified amount of grease. Reinstall the crank cap and tighten with the hex wrench. (Fig. 25)

Connect the connector and reinstall the handle. (Fig. 26)

CAUTION:

Be careful not to damage the terminals or lead wires especially when wiping out the old grease or installing the handle.

Do not tighten the crank cap excessively. It is made of resin and is subject to breakage.

To maintain product safety and reliability, repairs, mainte- nance or adjustment should be carried out by a Makita Authorized Service Center.
