6. 

Do not leave the tool running. Operate the tool 
only when hand-held.

7. 

Do not touch the drill bit or the workpiece 
immediately after operation; they may be 
extremely hot and could burn your skin.

8. 

Some material contains chemicals which may 
be toxic. Take caution to prevent dust inhala-
tion and skin contact. Follow material supplier 
safety data.

9. 

If the drill bit cannot be loosened even you 
open the jaws, use pliers to pull it out.

 In such a 

case, pulling out the drill bit by hand may result in 

injury by its sharp edge.

10. 

If something wrong with the tool such as 
abnormal sounds, stop operating immediately 
and ask your local Makita Service Center for 
repair.

11. 

Before operation, make sure that there is no 
buried object such as electric pipe, water pipe 
or gas pipe in the ground.

 Otherwise, the tool 

may touch them, resulting an electric shock, elec-
trical leakage or gas leak.

Safety instructions when using long drill bits

1. 

Never operate at higher speed than the max-
imum speed rating of the drill bit.

 At higher 

speeds, the bit is likely to bend if allowed to rotate 
freely without contacting the workpiece, resulting 

in personal injury.

2. 

Always start drilling at low speed and with the 
bit tip in contact with the workpiece.

 At higher 

speeds, the bit is likely to bend if allowed to rotate 
freely without contacting the workpiece, resulting 

in personal injury.

3. 

Apply pressure only in direct line with the bit 
and do not apply excessive pressure.

 Bits can 

bend causing breakage or loss of control, resulting 

in personal injury.

SAVE THESE INSTRUCTIONS.

WARNING:

 

DO NOT let comfort or familiarity 

with product (gained from repeated use) replace 
strict adherence to safety rules for the subject 
product. MISUSE or failure to follow the safety 
rules stated in this instruction manual may cause 
serious personal injury.

battery cartridge.

 Such conduct may result in a 

fire, excessive heat, or explosion.

9. 

Do not use a damaged battery.

10. 

The contained lithium-ion batteries are subject 
to the Dangerous Goods Legislation require-
ments. 

For commercial transports e.g. by third parties,

it from the tool and dispose of it in a safe 
place. Follow your local regulations relating to 
disposal of battery.

12. 

Use the batteries only with the products 

specified by Makita.

 Installing the batteries to 

non-compliant products may result in a fire, exces

-

sive heat, explosion, or leak of electrolyte.

13. 

If the tool is not used for a long period of time, 
the battery must be removed from the tool.

During and after use, the battery cartridge may 
take on heat which can cause burns or low 
temperature burns. Pay attention to the han-
dling of hot battery cartridges.

15. 

Do not touch the terminal of the tool imme-
diately after use as it may get hot enough to 
cause burns.

16. 

Do not allow chips, dust, or soil stuck into the 
terminals, holes, and grooves of the battery 
cartridge.

 It may cause heating, catching fire, 

burst and malfunction of the tool or battery car-

tridge, resulting in burns or personal injury.

17. 

Unless the tool supports the use near 
high-voltage electrical power lines, do not use 
the battery cartridge near high-voltage electri-
