After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
Screwdriving operation
First, slide the action mode change lever so that it
points to the
marking. Adjust 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.
NOTE:
•
Make sure that the driver bit is inserted straight in
the screw head, or the screw and/or bit may be
damaged.
•
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.
•
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.
Drilling operation
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
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.
First, slide the action mode change lever so that it
points to the
marking. The adjusting ring can be
aligned in any torque levels for this operation. Then
proceed as follows.
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 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.
