Operation
CAUTION:
• Always insert the battery cartridge all the way until it locks in
place. If you can see the red part on the upper side of the
button, it is not locked completely. Insert it fully until the red
part cannot be seen. If not, it may accidentally fall out of the
tool, causing injury to you or someone around you.
• When operating overhead, always make sure the battery
cartridge is locked securely so that it will not be fallen out of
the tool. If not, it may accidentally fall out of the tool, causing
injury to you or someone around you.
Hammer drilling operation (Fig. 16)
Set the change lever to the
location for the hole, then pull the trigger. Do not force the tool.
Light pressure gives best results. Keep the tool in position and
prevent it from slipping away from the hole.
Do not apply more pressure when the hole becomes clogged
with chips or particles. Instead, run the tool at an idle, then
remove from the hole. By repeating this several times, the
hole will be cleaned out.
CAUTION:
• When the bit begins to break through concrete or if the bit
strikes reinforcing rods embedded in concrete, the tool may
react dangerously. Maintain good balance and safe footing
while holding the tool firmly with both hands to prevent
dangerous reaction.
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.
Chipping/Scaling/Demolition (Fig. 17)
Set the change lever to the
both hands. Turn the tool on and apply slight pressure on the
tool so that the tool will not bounce around, uncontrolled.
Pressing very hard on the tool will not increase the efficiency.
Drilling operation (Fig. 18)
Use the optional drill chuck assembly. When installing it, refer
to ''Installing or removing drill bit'' described on the previous
page. You can drill up to 13 mm diameter in metal and up to
27 mm diameter in wood.
Set the change lever so that the pointer points to the
symbol.
Use a cutting lubricant when drilling metals. The exception is
brass which should be drilled dry.
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 bit, decrease the tool performance
and shorten the service life of the tool.
• Never use ''rotation with hammering'' when the drill chuck
assembly is installed on the tool. The drill chuck assembly
may be damaged.
symbol. Position the bit at the
symbol. Hold the tool firmly with
Blow-out bulb (Fig. 19)
Use the blow-out bulb to clean out the hole.
Dust cup (Fig. 20)
Use the dust cup to prevent dust from falling over the tool and
on yourself when performing overhead drilling operations.
Attach the dust cup to the bit. The size of bits which the dust
cup can be attached to is as follows.
Dust cup 5
Dust cup 9
Foot
Remove the foot when you use the battery cartridge B2417.
This will help to place the tool steady. (Fig. 21)
Install the foot when you use the battery cartridge B2430.
This will help to place the tool steady. (Fig. 22)
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and the battery
cartridge is removed before carrying out any work on the tool.
Replacement of carbon brushes (Fig. 23 & 24)
Remove and check the carbon brushes regularly. Replace
when they wear down to the limit mark. Keep the carbon
brushes clearn and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only
identical carbon brushes.
Use a screwdriver to remove the brush holder caps. Take out
the worn carbon brushes, insert the new ones and secure the
brush holder caps.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
