Operation; Maintenance - Makita HR160D Instruction Manual

NOTE:
The depth gauge cannot be used at the position
•
where the depth gauge strikes against the gear
housing.
Dust cup
001300
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 as shown in the
figure. The size of bits which the dust cup can be
attached to is as follows.
Dust cup 5
Dust cup 9

OPERATION

Hammer drilling operation
Position the bit at the desired location for the hole, then
pull the switch 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 the bit partially from the hole. By
repeating this several times, the hole will be cleaned out
and normal drilling may be resumed.
CAUTION:
There is a tremendous and sudden twisting force
•
exerted on the tool/bit at the time of hole
break-through, when the hole becomes clogged
with chips and particles, or when striking reinforcing
rods embedded in the concrete. Always use the
side grip (auxiliary handle) and firmly hold the tool
by both side grip and switch handle during
operations. Failure to do so may result in the loss of
control of the tool and potentially severe injury.

Use the optional drill chuck assembly (consisting of drill
chuck and chuck adapter assembly). When installing it,
refer to "Installing or removing drill bit" described on the
previous page.
Set the action mode changing knob to "rotation only".
You can drill up to 13 mm diameter in metal and up to 20
mm diameter in wood.
CAUTION:
Never use "rotation with hammering" when the drill
•
chuck assembly is installed on the tool. The drill
chuck assembly may be damaged.
Also, the drill chuck will come off when reversing
the tool.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before attempting to
perform inspection or maintenance.
Never use gasoline, benzine, thinner, alcohol or the
•
like. Discoloration, deformation or cracks may
result.
To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by
Makita Authorized Service Centers, always using Makita
replacement parts.
