Additional Safety Rules - Makita HR2300 Instruction Manual

Safety instructions when using long drill bits with
rotary hammers
1. 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.
2. 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.

ADDITIONAL SAFETY RULES

1. Wear a hard hat (safety helmet), safety glasses
and/or face shield. Ordinary eye or sun glasses
are NOT safety glasses. It is also highly recom-
mended that you wear a dust mask and thickly
padded gloves.
2. Be sure the bit is secured in place before opera-
tion.
3. Under normal operation, the tool is designed to
produce vibration. The screws can come loose
easily, causing a breakdown or accident. Check
tightness of screws carefully before operation.
4. In cold weather or when the tool has not been
used for a long time, let the tool warm up for a
while by operating it under no load. This will
loosen up the lubrication. Without proper warm-
up, hammering operation is difficult.
5. Always be sure you have a firm footing. Be sure
no one is below when using the tool in high loca-
tions.
6. Hold the tool firmly with both hands.
7. Keep hands away from moving parts.
8. Do not leave the tool running. Operate the tool
only when hand-held.
9. Do not point the tool at any one in the area when
operating. The bit could fly out and injure some-
one seriously.
10. Do not touch the bit, parts close to the bit, or
workpiece immediately after operation; they may
be extremely hot and could burn your skin.
11. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.
12. Do not touch the power plug with wet hands.
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 instruc-
tion manual may cause serious personal injury.
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. For continuous opera-
tion, pull the switch trigger and then push in the lock but-
ton and then release the switch trigger. To stop the tool
from the locked position, pull the switch trigger fully, then
release it.
Reversing switch action (Fig. 2)
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.
• If the switch trigger can not be depressed, check to see
that the reversing switch is fully set to position
side) or (B side).
This tool has a reversing switch to change the direction
of rotation. Move the reversing switch lever to the
position (A side) for clockwise rotation or to the
tion (B side) for counterclockwise rotation.
Selection action mode (Fig. 3)
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
m
For rotation with hammering, turn the knob so that the
arrow on the knob points toward the
tool body.
CAUTION:
• Always set the knob fully to your desired mode symbol.
If you operate the tool with the knob positioned half-
way between the mode symbols, the tool may be dam-
aged.
• Use the knob after the tool comes to a complete stop.
Torque limiter
The torque limiter will actuate when a certain torque level
is reached. The motor will disengage from the output
shaft. When this happens, the bit will stop turning.
CAUTION:
• As soon as the torque limiter actuates, switch off the
tool immediately. This will help prevent premature wear
of the tool.
• Bits such as hole saw, which tend to pinch or catch
easily in the hole, are not appropriate for this tool. This
is because they will cause the torque limiter to actuate
too frequently.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
