ENGLISH

CAUTION:

 

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.

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.

CAUTION:

 

Avoid drilling in material that you 

suspect contains hidden nails or other things that 
may cause the drill bit to bind or break.

CAUTION:

 

If the tool is operated continuously 

until the battery cartridge has discharged, allow 
the tool to rest for 15 minutes before proceeding 
with a fresh battery.

Lanyard (tether strap) connection

Safety warnings specific for use at height

Read all safety warnings and instructions.

 Failure 

to follow the warnings and instructions may result in 

serious injury.

1. 

Always keep the tool tethered when working 
"at height". Maximum lanyard length is 2 m 
(6.5 ft).
The maximum permissible fall height for lan-
yard (tether strap) must not exceed 2 m (6.5 ft).

2. 

Use only with lanyards appropriate for this tool 
type and rated for at least 5.0 kg (11.0 lbs).

3. 

Do not anchor the tool lanyard to anything on 
your body or on movable components. Anchor 
the tool lanyard to a rigid structure that can 
withstand the forces of a dropped tool.

4. 

Make sure the lanyard is properly secured at 
each end prior to use.

5. 

Inspect the tool and lanyard before each use 
for damage and proper function (including 
fabric and stitching). Do not use if damaged or 
not functioning properly.

6. 

Do not wrap lanyards around or allow them to 
come in contact with sharp or rough edges.

7. 

Fasten the other end of the lanyard outside 
the working area so that a falling tool is held 
securely.

8. 

Attach the lanyard so that the tool will move 
away from the operator if it falls.

 Dropped tools 

will swing on the lanyard, which could cause injury 

or loss of balance.

9. 

Do not use near moving parts or running 
machinery.

 Failure to do so may result in a crush 

or entanglement hazard.

10. 

Do not carry the tool by the attachment device 
or the lanyard.

11. 

Only transfer the tool between your hands 
while you are properly balanced.

12. 

Do not attach lanyards to the tool in a way that 

keeps guards, switches or lock-offs from oper

-

ating properly.

13. 

Avoid getting tangled in the lanyard.

14. 

Keep lanyard away from the cutting area of the 
tool.

15. 

Use multi-action and screw gate type cara-
bineers. Do not use single action spring clip 
carabineers.

16. 

In the event the tool is dropped, it must be 
tagged and removed from service, and should 
be inspected by a Makita Factory or Authorized 
Service Center.

MAINTENANCE

CAUTION:

 

Always be sure that the tool is 

switched off and the battery cartridge is removed 

before attempting to perform inspection or 
maintenance.

alcohol or the like. Discoloration, deformation or
