Operation - Makita DHP459 Instruction Manual

Adjusting the fastening torque
Fig.9
The fastening torque can be adjusted in 16 steps by turning
the adjusting ring so that the graduations are aligned with
the arrow on the tool body. The fastening torque is
minimum when the number 1 is aligned with the arrow, and
maximum when the number 16 is aligned with the arrow.
Before the actual operation, drive a trial screw into your
material or a piece of duplicate material to determine
which torque level is required for a particular application.
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.
Installing or removing the driver bit or drill bit
Fig.10
Turn the sleeve counterclockwise to open the chuck jaws.
Place the bit in the chuck as far as it will go. Turn the
sleeve clockwise to tighten the chuck.
To remove the bit, turn the sleeve counterclockwise.
Installing the hook
Fig.11
The hook is convenient for temporarily hanging the tool.
This can be installed on either side of the tool.
To install the hook, insert it into a groove in the tool
housing on either side and then secure it with a screw. To
remove, loosen the screw and then take it out.
Installing the bit holder (Optional accessory)
Fig.12
Fit the bit holder into the protrusion at the tool foot on
either right or left side and secure it with a screw.
When not using the driver bit, keep it in the bit holders.
Bits 45 mm long can be kept there.

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.
Hold the tool firmly with one hand on the grip and the
other hand on the bottom of the battery cartridge to
control the twisting action.
CAUTION:
Do not cover vents, or it may cause overheating
•
and damage to the tool.

Hammer drilling operation
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.
First, turn the action mode changing ring so that the
arrow on the tool body points to the
adjusting ring can be aligned in any torque levels for this
operation.
Be sure to use a tungsten-carbide tipped bit.
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.
Blow-out bulb (optional accessory)
Fig.14
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
Screwdriving operation
Fig.15
First, turn the action mode changing ring so that the
arrow on the tool body points to the
the adjusting ring to the proper torque level for your work.
Then proceed as follows.
Place the point of the driver bit in the screw head and
apply pressure to the tool. Start the tool slowly and then
increase the speed gradually. Release the switch trigger
as soon as the clutch cuts in.
CAUTION:
Make sure that the driver bit is inserted straight in
•
the screw head, or the screw and/or bit may be
damaged.
NOTE:
When driving wood screw, predrill a pilot hole 2/3
•
the diameter of the screw. It makes driving easier
and prevents splitting of the workpiece.
Drilling operation
First, turn the adjusting ring so that the pointer points to
the marking. Then proceed as follows.
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.
