 Groove 

2.

 Hook 

3.

 Screw

The hook is convenient for temporarily hanging the tool. 

This can be installed on either side of the tool.

To install the hook, insert it into a groove in the tool 

housing on either side and then secure it with a screw. 

To remove, loosen the screw and then take it out.

OPERATION

CAUTION:

 

Always use the side grip (auxiliary 

handle) and firmly hold the tool by both side grip 

and switch handle during operations.

CAUTION:

 

Always make sure that the work-

piece is secured before operation.

NOTE:

 If the battery cartridge is in low temperature, 

the tool’s capability may not be fully obtained. In this 

case, warm up the battery cartridge by using the 

tool with no load for a while to fully obtain the tool’s 

capability.

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 opera-

tions.

 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 auto-

matically centers itself during operation. This does not 

affect the drilling precision.

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.

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. When installing it, refer to the 

section “Installing or removing drill bit”.
