Installing or removing the bit (Fig. 8)
To remove the bit, pull the locator. Then grasp the bit with
a pair of pliers and pull the bit out of the magnetic bit
holder. Sometimes, it helps to wiggle the bit with the pliers
as you pull. (Fig. 9)
To install the bit, push it firmly into the magnetic bit holder.
Then install the locator by pushing it firmly back.
Installing hook
WARNING:
• Use the hanging/mounting parts for their intended
purposes only, e.g., hanging the tool on a tool belt
between jobs or work intervals.
• Be careful not to overload the hook as too much
force or irregular overburden may cause damages
to the tool resulting in personal injury.
CAUTION:
• When installing the hook, always secure it with the
screw firmly. If not, the hook may come off from the
tool and result in the personal injury.
• Make sure to hang the tool securely before
releasing your hold. Insufficient or unbalanced
hooking may cause falling off and you may be injured.
(Fig. 10)
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
Screwdriving operation (Fig. 11)
Fit the screw on the point of the bit and place the point of
the screw on the surface of the workpiece to be fastened.
Apply pressure to the tool and start it. Withdraw the tool
as soon as the clutch cuts in. Then release the switch
trigger.
CAUTION:
• When fitting the screw onto the point of the bit, be
careful not to push in on the screw. If the screw is
pushed in, the clutch will engage and the screw will
rotate suddenly. This could damage a workpiece or
cause an injury.
• Make sure that the bit is inserted straight in the screw
head, or the screw and/or bit may be damaged.
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.

NOTE:
• Some items in the list may be included in the tool
package as standard accessories. They may differ from
country to country.
Noise
The typical A-weighted noise level determined according
to EN62841-2-2:
Model DFS441
Sound pressure level (L
Uncertainty (K): 3 dB (A)
The noise level under working may exceed 80 dB (A).
Model DFS451
Sound pressure level (L
Uncertainty (K): 3 dB (A)
The noise level under working may exceed 80 dB (A).
• The declared noise emission value(s) has been
measured in accordance with a standard test method
and may be used for comparing one tool with another.
• The declared noise emission value(s) may also be
used in a preliminary assessment of exposure.
WARNING:
• Wear ear protection.
• The noise emission during actual use of the power
tool can differ from the declared value(s)
depending on the ways in which the tool is used
especially what kind of workpiece is processed.
• Be sure to identify safety measures to protect the
operator that are based on an estimation of
exposure in the actual conditions of use (taking
account of all parts of the operating cycle such as
the times when the tool is switched off and when it
is running idle in addition to the trigger time).
Vibration
The vibration total value (tri-axial vector sum) determined
according to EN62841-2-2:
Work mode: screwdriving without impact
Vibration emission (a
Uncertainty (K): 1.5 m/s
• The declared vibration total value(s) has been
measured in accordance with a standard test method
and may be used for comparing one tool with another.
• The declared vibration total value(s) may also be used
in a preliminary assessment of exposure.
