FUNCTIONAL DESCRIPTION

CAUTION: 

• Always be sure that the tool is switched off and 

unplugged before adjusting or checking function on the 
tool. 

Switch action (Fig. 1)

CAUTION: 

• Before plugging in the tool, always check to see that 

the switch trigger actuates properly and returns to the 
"OFF" position when released. 

To start the tool, simply pull the switch trigger. Tool speed 
is increased by increasing pressure on the switch trigger. 
Release the switch trigger to stop. 

Lighting up the lamps

For Models HR2811F, HR2811FT (Fig. 2)

CAUTION: 

• Do not look in the light or see the source of light 

directly.

To turn on the lamp, pull the trigger. Release the trigger to 
turn it off. 

NOTE: 

• Use a dry cloth to wipe the dirt off the lens of lamp. Be 

careful not to scratch the lens of lamp, or it may lower 
the illumination. 

Reversing switch action (Fig. 3)

This tool has a reversing switch to change the direction of 
rotation. Depress the reversing switch lever from the A 
side for clockwise rotation or from the B side for 
counterclockwise rotation. 

CAUTION: 

• Always check the direction of rotation before operation. 

• Use the reversing switch only after the tool comes to a 

complete stop. Changing the direction of rotation 
before the tool stops may damage the tool. 

• When you operate the tool in counterclockwise 

rotation, the switch trigger is pulled only halfway and 
the tool runs at half speed.

Changing the quick change chuck for 
SDS-plus

For model HR2810T, HR2811FT 

The quick change chuck for SDS-plus can be easily 
exchanged for the quick change drill chuck. 

Removing the quick change chuck for SDS-plus 
(Fig. 4)

CAUTION: 

• Before removing the quick change chuck for SDS-plus, 

always remove the bit. 

Grasp the change cover of the quick change chuck for 
SDS-plus and turn in the direction of the arrow until the 
change cover line moves from the   symbol to the   
symbol. Pull forcefully in the direction of the arrow. 

Attaching the quick change drill chuck 
(Fig. 5)

Check the line of the quick change drill chuck shows the 

 symbol. Grasp the change cover of the quick change 

drill chuck and set the line to the   symbol. Place the 
quick change drill chuck on the spindle of the tool. 
Grasp the change cover of the quick change drill chuck 
and turn the change cover line to the   symbol until a 
click can clearly be heard. 

Selecting the action mode

For Model HR2800 (Fig. 6)

This tool employs an action mode changing knob. Select 
one of the two modes suitable for your work needs by 
using this knob. 
For rotation only, turn the knob so that the arrow on the 
knob points toward the   symbol on the tool body. 
For rotation with hammering, turn the knob so that the 
arrow on the knob points toward the 

 symbol on the tool 

body. 

CAUTION: 

• Always set the knob fully to your desired mode symbol. 

If you operate the tool with the knob positioned halfway 
between the mode symbols, the tool may be damaged. 

• Use the knob after the tool comes to a complete stop.

For models HR2810, HR2810T, HR2811F, HR2811FT
Rotation with hammering (Fig. 7)

For drilling in concrete, masonry, etc., rotate the action
