3. Wear ear protectors when using the tool for
extended periods. Prolonged exposure to high
intensity noise can cause hearing loss.
4. Wear a hard hat (safety helmet), safety glasses
and/or face shield. It is also highly recom-
mended that you wear a dust mask and thickly
padded gloves.
5. Be sure the bit is secured in place before opera-
tion.
6. 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.
7. In cold weather or when the tool has not been
used for a long time, let the tool warm up for sev-
eral minutes by operating it under no load. This
will loosen up the lubrication. Without proper
warm-up, hammering operation is difficult.
8. Always be sure you have a firm footing.
9. Be sure no one is below when using the tool in
high locations.
10. Hold the tool firmly with both hands.
11. Keep hands away from moving parts.
12. Do not leave the tool running. Operate the tool
only when hand-held.
13. Do not point the tool at any one in the area when
operating. The bit could fly out and injure some-
one seriously.
14. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
SAVE THESE INSTRUCTIONS.
OPERATING INSTRUCTIONS
Installing or removing battery cartridge (Fig. 1)
• Always switch off the tool before insertion or removal of
the battery cartridge.
• To remove the battery cartridge, pull out the set plate
on the tool and grasp both sides of the cartridge while
withdrawing it from the tool.
• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Snap the set plate back into place. Be sure
to close the set plate fully before using the tool to pre-
vent the battery cartridge from accidentally falling out of
the tool.
Installing or removing drill bit (Fig. 2, 3, 4)
CAUTION:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before installing or removing
the bit.
Clean the bit shank and apply the bit grease provided to
it before installing the bit.
Insert the bit into the tool. Turn the bit and push it in until
it engages.
If the bit cannot be pushed in, remove the bit. Pull the
chuck cover down a couple of times. Then insert the bit
again. Turn the bit and push it in until it engages.
After installing, always make sure that the bit is securely
held in place by trying to pull it out.
To remove the bit, pull the chuck cover down all the way
and pull the bit out.
Depth gauge (Fig. 5)
The depth gauge is convenient for drilling holes of uni-
form depth. Insert the depth gauge into the hole in the
grip base. Adjust the depth gauge to the desired depth
and then tighten the clamp screw to secure the depth
gauge.
NOTE:
The depth gauge cannot be used at the position where
the depth gauge strikes against the gear housing.
Switch action (Fig. 6)
CAUTION:
Before inserting the battery cartridge into 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 trigger. Tool speed is
increased by increasing pressure on the trigger. Release
the trigger to stop.
Reversing switch action
This tool has a reversing switch to change the direction of
rotation. Move the lever to the n position for clockwise
rotation or the o position 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.
• Do not pull the switch trigger when the reversing switch
lever is in the neutral position. If you pull the trigger
forcibly, the switch may be damaged.
Selecting the action mode (Fig. 7)
This tool employs an action mode changing knob. Select
one of three 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
body. For hammering only, turn the knob so that the
arrow on the knob points toward the x mark on the tool
body. For rotation with hammering, turn the knob so that
the arrow on the knob points toward the
tool body.
CAUTION:
• The action mode changing knob may not be turned to
your desired mode mark when the tool is not running.
In this case, pull the switch trigger half-way and turn the
knob while the tool is running under no load at low
speed.
• Always set the knob fully to your desired mode mark. If
you operate the tool with the knob positioned half-way
between the mode marks, the tool may be damaged.
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.
• Hole saws, core bits, diamond core bits, etc. cannot be
used with this tool. They tend to pinch or catch easily in
the hole. This will cause the torque limiter to actuate
too frequently.
