Screwdriving Operation; Drilling Operation; Maintenance - Makita BDF459 Instruction Manual

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.

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.
There is a tremendous force exerted on the tool/bit
•
at the time of hole break through. Hold the tool
firmly and exert care when the bit begins to break
through the workpiece.
A stuck bit can be removed simply by setting the
•
reversing switch to reverse rotation in order to back
out. However, the tool may back out abruptly if you
do not hold it firmly.
Always secure small workpieces in a vise or with a
•
similar hold-down device.
If the tool is operated continuously until the battery
•
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.
Do not pull the switch trigger repeatedly when the
•
motor is locked. It may damage the tool.
Drilling in wood
When drilling in wood, the best results are obtained with
wood drills equipped with a guide screw. The guide
screw makes drilling easier by pulling the bit into the
workpiece.
Drilling in metal
To prevent the bit from slipping when starting to make a
hole, make an indentation with a center-punch and
hammer at the point to be drilled. Place the point of the
bit in the indentation and start drilling.
Use a cutting lubricant when drilling metals. The
exceptions are iron and brass which should be drilled dry.

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,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
