Adjusting the fastening torque
(screwdriver mode “ ”) (Fig. 10)
The fastening torque can be adjusted in 21 steps by
turning the adjusting ring so that its graduations are
aligned with the pointer on the tool body.
First, slide the action mode change lever to the position of
symbol.
The fastening torque is minimum when the number 1 is
aligned with the pointer, and maximum when the marking
is aligned with the pointer. The clutch will slip at various
torque levels when set at the number 1 to 21. Before
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.
NOTE:
• The adjusting ring does not lock when the pointer is
positioned only halfway between the graduations.
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 side grip (auxiliary handle)
(Fig. 11)
Always use the side grip to ensure operating safety.
Insert the side grip so that the groove on the arm fit in one
of the counter parts on the tool. Then tighten the grip by
turning clockwise.
Depending the operations, you can install the side grip
either right or left side of the tool.
Installing or removing driver bit or drill bit
(Fig. 12)
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 bit holder (Fig. 13)
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.
Hook (Fig. 14)
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.
OPERATION (Fig. 15)
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
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.
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.
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.
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.
