Diamond core drilling

When performing diamond core drilling operations,

always set the change lever to the position to use "rotation only" action.

CAUTION:

•If performing diamond core drilling operations using "rotation with hammering" action, the diamond core bit may be damaged.

MAINTENANCE

CAUTION:

For Model HR2800, HR28010, HR2810F

Use the optional drill chuck assembly. When installing it, refer to "Installing or removing the bit" described on the previous page.

Set the action mode changing knob so that the pointer points to the symbol.

For model HR2810T, HR2811FT

Use the quick change drill chuck as standard equipment. When installing it, refer to "changing the quick change chuck for SDS-plus " described on the previous page.

Hold the ring and turn the sleeve counterclockwise to open the chuck jaws. Place the bit in the chuck as far as it will go. Hold the ring firmly and turn the sleeve clockwise to tighten the chuck. To remove the bit, hold the ring and turn the sleeve counterclockwise.

Set the action mode changing knob to the symbol. You can drill up to 13 mm diameter in metal and up to 32 mm diameter in wood.

CAUTION:

•Never use "rotation with hammering" when the quick change drill chuck is installed on the tool. The quick change drill chuck may be damaged.

Also, the drill chuck will come off when reversing the tool.

•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 performance and shorten the service life of the tool.

•There is a tremendous twisting force exerted on the tool/bit at the time of hole breakthrough. Hold the tool firmly and exert care when the bit begins to break through the workpiece.

•Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.

•Never use gasoline, benzine, thinner, alcohol or

the like. Discoloration, deformation or cracks may result.

To maintain product SAFETY and RELIABILITY, repairs, carbon brush inspection and replacement, any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts.
