Dust cup set (optional accessory)

NOTICE:

If you purchase the dust cup set as 

optional accessory, the standard side grip cannot 

be used with the dust cup set being installed on 

the tool.

 When the dust cup set is installed on the 

tool, remove the grip from the standard side grip, and 

then attach it to the optional grip base set.

NOTICE:

Do not use the dust cup set when drill-

ing in metal or similar.

 It may damage the dust cup 

set due to the heat produced by small metal dust or 

similar. Do not install or remove the dust cup set with 

the drill bit installed in the tool. It may damage the 

dust cup set and cause dust leak.

Before installing the dust cup set, remove the bit from 

the tool if installed.

Install the spacer so that the grooves on the spacer fit 

in the protrusions on the tool barrel while widening it. 

Be careful for the spring not to come off from the slit of 

spacer.

Install the side grip (optional grip base set and the grip 

removed from standard side grip) so that the groove on 

the grip fit in the protrusion on the spacer. Turn the grip 

clockwise to secure it.

NOTE:

 If the cap comes off from the dust cup, attach 

it with its printed side facing up so that groove on the 

cap fits in the inside periphery of the attachment.

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.

Fig.21

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”.
