Electronic Function - Makita HR008G Instruction Manual

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 switches or trigger-lock (if supplied)
from operating properly.
13. Avoid getting tangled in the lanyard.
14. Keep lanyard away from the drilling area of the
tool.
15. Use a locking carabiner (multi-action and
screw gate type). Do not use single action
spring clip carabiners.
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.
Accidental restart preventive
function
If you install the battery cartridge while pulling the
switch trigger, the tool does not start. To start the tool,
release the switch trigger, and then pull the switch
trigger.
Torque limiter
NOTICE:
As soon as the torque limiter actuates,
switch off the tool immediately. This will help pre-
vent premature wear of the tool.
NOTICE:
Drill bits such as hole saw, which tend
to pinch or catch easily in the hole, are not appro-
priate for this tool. This is because they will cause
the torque limiter to actuate too frequently.
The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the
output shaft. When this happens, the drill bit will stop
turning.

Electronic function

The tool is equipped with the electronic functions for
easy operation.
• Electric brake
This tool is equipped with an electric brake. If the
tool consistently fails to quickly cease to function
after the switch trigger is released, have the tool
serviced at a Makita service center.
• Constant speed control
The speed control function provides the constant
rotation speed regardless of load conditions.
• Active Feedback sensing Technology
If the tool is swung at the predetermined accelera-
tion during operation, the motor is forcibly stopped
to reduce the burden on the wrist.
NOTE: This function does not work if the acceleration
does not reach the predetermined one when the tool
is swung.
NOTE: If the bit is swung at the predetermined
acceleration during chipping, scaling, or demolishing,
the motor is forcibly stopped. In this case, release
the switch trigger, and then pull the switch trigger to
restart the tool.
ASSEMBLY
CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.
