Hammer drilling operation

CAUTION: There is tremendous and sudden twisting force exerted on the tool/drill bit at the time of hole break-through, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations. Failure to do so may result in the loss of control of the tool and potentially severe injury.

Set the action mode changing knob to the symbol. Position the drill bit at the desired location for the hole, then pull the switch trigger. Do not force the tool. Light pressure gives best results. Keep the tool in position and prevent it from slipping away from the hole.

Do not apply more pressure when the hole becomes clogged with chips or particles. Instead, run the tool at an idle, then remove the drill bit partially from the hole. By repeating this several times, the hole will be cleaned out and normal drilling may be resumed.

NOTE: Eccentricity in the drill bit rotation may occur while operating the tool with no load. The tool automatically centers itself during operation. This does not affect the drilling precision.

Set the action mode changing knob to the symbol. 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.

Fig.36

Drilling in wood or metal

CAUTION: Hold the tool firmly and exert care when the drill bit begins to break through the workpiece. There is a tremendous force exerted on the tool/drill bit at the time of hole break through.
CAUTION: A stuck drill bit can be removed simply by setting the reversing switch to reverse rotation in order to back out. However, the tool may back out abruptly if you do not hold it firmly.
CAUTION: Always secure workpieces in a vise or similar hold-down device.

NOTICE: Never use “rotation with hammering” when the drill chuck is installed on the tool. The drill chuck may be damaged.
Also, the drill chuck will come off when reversing the tool.
NOTICE: 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 drill bit, decrease the tool performance and shorten the service life of the tool.

Set the action mode changing knob to the symbol.

Installing drill chuck set

Optional accessory

Attach the chuck adapter to a keyless drill chuck to which 1/2″-20 size screw can be installed, and then install them to the tool. For details on how to install the adapter into the chuck, refer to the instructions on installing drill bit.

Beating dust on the filter

Optional accessory

CAUTION: Do not turn the dial on the dust case while the dust case is removed from the dust collection system. Doing so may cause dust inhalation.
CAUTION: Always switch off the tool when turning the dial on the dust case. Turning the dial while the tool is running may result in the loss of control of the tool.

By beating the dust on the filter inside the dust case, you can keep the vacuum efficiency and also reduce the number of times to dispose of the dust.
Turn the dial on the dust case three times after collecting every 50,000 mm3 of dust or when you feel the vacuum performance declined.

NOTE: 50,000 mm3 of dust equivalents to drilling 10 holes of ø10 mm and 65 mm depth.
